Description
BACKGROUND OF THE INVENTION
[0001] 1. The Field of the Invention
[0002] The present invention relates to biowaste containers. In
more particular, the present invention relates to a multipart
biowaste container for use in a surgical setting.
[0003] 2. The Relevant Technology
[0004] A great amount of attention has been focused on the
appropriate disposition of blood, tissue, and other biological
materials that are produced in modern surgical settings. Much of
this focus results from concerns regarding contamination, possible
infection, and exposure to such materials, as well as bioethical
considerations directed to proper disposition of human tissues.
[0005] As a result, a number of basins and other specialized
receptacles for blood, tissue, and other biological materials have
been developed. Typically, during a medical procedure such blood,
tissue, and biological materials are deposited into specially
designed containers and/or receptacles until the completion of the
procedures. After the completion of the procedure, the attending
staff can then quickly and readily identify blood, tissues, and
other biological materials that require special handling or special
disposal procedures. The attending staff can then simply discard of
the entire container without the need to separately attend to
individual biowaste elements.
[0006] Some biowaste containers suffer from a number of
deficiencies. For example, one problem presented by such biowaste
containers is that they must be sufficiently large to accommodate
the volume of biowaste that is typically produced during a typical
surgical procedure. As a result, the biowaste containers must
either have a fairly large footprint or have a sufficient depth to
accommodate the required amount of biological waste.
[0007] Due to the fact that surgical working surfaces available to
hold the biological waste container must also accommodate a number
of other surgical implements, biological waste containers covering
a large surface area are typically impractical. As a result, a
biological waste container covering a smaller surface area but
having a greater depth relative to their overall size are typically
provided in such surgical settings. While biological waste
containers having a greater height relative to their overall size
are more practical due to surgical area surface constraints, such
waste containers can be somewhat cumbersome to use. Additionally,
the greater height can make it difficult to reach other tools or
implements located close to the biological waste container. In some
circumstances, attempts to access implements positioned adjacent
the biological waste container can even result in tipping of the
biological waste container when inadvertently bumped or contacted
by a practitioner during surgery.
[0008] The size of such biological waste containers can also be
fairly cumbersome to ship and store due their overall size. This
can be particularly problematic where the biological waste
container includes a lid or other secondary member. To alleviate
this problem, the lids are sometimes shipped in place on the
biological waste container. During preparation for surgery, the
surgical staff simply removes the lid and places it to the side
until the end of surgery. While this alleviates some of the
problems with storage and shipping of the lid member, it can be
inconvenient to find a place to store the lid during surgery. After
the surgery is completed it can be difficult to locate the lid in
order to place it on biological waste container for disposal.
[0009] Some biological waste container designs utilize a lid that
nests on the underside of the biological waste container. During
the procedure the lid remains in contact with the biological waste
container until the procedure is completed. The lid can then be
removed from the bottom of the biological waste container and
placed over the top of the biological waste container to secure the
contents of the biological waste container during disposal.
Unfortunately, where the biological waste container becomes
somewhat full of blood, tissue or other biological materials,
removal of the lid from beneath the biological waste container can
result in inadvertent spillage or other issuance of such materials
from the biological waste container. As a result of the various
complications and limitations of existing biological waste
containers practitioners are forced to select biological waste
containers having the least number of deficiencies for the type of
procedure being performed. However, this can be impractical due to
the purchasing constraints and storage realities inherent in
hospital and surgical center economics.
BRIEF SUMMARY OF THE INVENTION
[0010] The present invention is directed to a multi-part biowaste
container configured to provide a low profile design while
providing sufficient storage volume to accommodate the amount of
blood, tissues, and other biological materials generated during a
typical surgical procedure. In one embodiment, the multi-part
biowaste container includes an anti-splash container, a dual
purpose lid container, and a supplemental container. The use of
three separate container members increases the total volume and
storage capacity of the biowaste containers while minimizing the
overall profile or height of the containers.
[0011] To reduce the amount of surgical space occupied by three
separate containers, the containers can be placed in various useful
or convenient locations as needed during surgery. Because the
containers have a relatively low profile relative to their overall
size, the containers are not easily bumped or tipped during the
procedure. According to one embodiment of the present invention, an
adhesive pad is provided in connection with the bottom surface of
one or more of the containers. The adhesive pad allows the
containers to be adhered to the working surface to prevent
inadvertent knocking or spilling of the container. This also allows
the containers to be positioned in unconventional locations such as
directly on the patient's chest or abdomen.
[0012] The anti-splash container includes a basin and a splash
guard positioned to cover the basin. The basin is selected to have
an overall surface area that corresponds to the surface area of
biological waste containers typically used in a surgical setting.
As previously discussed, the height of the wall of the basin is
selected to provide an overall low profile to facilitate use of the
container in a restricted surgical settings. The splash guard is
provided to cover to the basin. The splash guard allows the
introduction of fluid materials into the biological waste container
in a manner which contains the fluids from inadvertent splashing or
other release of the fluids once placed within the basin. According
to one embodiment of the present invention, the splash guard
includes a silt valve that allows for the introduction of blood,
tissues or other biological materials into the basin in a safe and
advantageous manner.
[0013] According to another embodiment of the present invention, an
absorbent pad is provided in the bottom of the basin. The absorbent
pad is configured to absorb blood, fluids, and other biological
materials in a manner to facilitate containment of the biological
materials in the basin. The absorbent pad can include chemical
properties that solidify, or coagulate the biological materials
such as in a gel form to maximize the containment of such
materials.
[0014] The dual purpose lid container is provided as a secondary
receptacle for receiving biological materials. The dual purpose lid
container has overall dimensions that are similar to the
anti-splash container. For example, the dual purpose lid container
has a somewhat low profile while conforming to the overall
footprint typically utilized biological waste containers. The dual
purpose lid container includes a pour spout positioned at a comer
of the upper rim of the dual purpose lid container. The pour spout
allows for controlled and advantageous drainage of any excess
blood, fluid, or biological materials from the dual purpose lid
container into a secondary container.
[0015] Typically such blood, fluid, or other biological materials
are drained from the dual purpose lid container into the slit valve
of the anti-splash container. In this manner, all biological
materials are consolidated in a manner allowing the containers to
be easily and quickly be disposed of through proper procedures.
Once the dual purpose lid container has been appropriately drained,
the dual purpose lid container is configured to fit over the
anti-splash container as a secondary and reliable containment
mechanism. As a result, during disposal, the anti-splash container
can be handled without leakage, splashing, or spilling of blood,
fluids, or other materials from the anti-splash container.
[0016] According to one embodiment of the present said invention,
an absorbent pad is also provided in connection with the dual
purpose lid container. The absorbent pad performs essentially the
same function as the absorbent pad of the anti-splash container. In
this embodiment, the overall depth of the dual purpose lid
container is designed such that when the absorbent pad of the dual
purpose lid container is saturated with blood, fluid, or other
materials, the saturated absorbent pad does not interfere with
proper operation of the dual purpose lid container in covering and
cooperatively engaging the anti-splash container. According to
another embodiment of the present invention, the rim of the dual
purpose lid container is slightly narrower than the rim of the
anti-splash container. As a result, the rim of the dual purpose lid
container is not inadvertently contacted and loosened relative to
the anti-splash container.
[0017] The supplementary container is provided as a tertiary
receptacle for biological materials in addition to the anti-splash
container and the dual purpose lid container. The supplementary
container also has dimensions similar to the anti-splash container
and the dual purpose lid container. According to one embodiment of
the present invention, the supplementary container is not only
provided as a supplementary biowaste container, but may be utilized
for other surgical purposes, such as a receptacle for saline or
other flushing fluids. The supplementary container may also be
utilized to hold surgical instruments, or gauze pads. The
supplementary container can also be designed to provide a lid for
the anti-splash container in the event that the volume of fluid in
the dual purpose lid container is in excess of that which can be
accommodated by the anti-splash container. According to one
embodiment of the present invention, the dual purpose lid container
and the supplementary container also utilize adhesive pads or other
gripping surfaces to minimize slippage or tipping of these
containers.
[0018] The dual purpose lid container and supplementary container
are configured to nest beneath the anti-splash container during
shipping. By having the ability to nest beneath the anti-splash
container, the dual purpose lid container and supplementary
container provide an overall low profile and efficient storage
volume for the multipart biowaste container. This can substantially
reduce the cost of packaging and storage of the multipart biowaste
containers while facilitating preparation for the surgical
procedure to be performed.
[0019] Once the multipart biowaste container is ready to be
utilized in the surgical setting, the anti-splash container, dual
purpose lid container, and supplementary container can be separated
from one another. By utilizing three separate containers, the
overall storage volume of the three containers is comparable to
that of other biowaste containers without encumbering substantial
amounts of the working surface or interfering with the use of other
instruments and materials positioned on the working surface.
According to one embodiment of the present invention, the height of
the walls of one or more of the anti-splash container, the dual
purpose lid container, and/or the supplementary container is less
than two inches. According to another embodiment, when the
anti-splash container, dual purpose lid container, the
supplementary container are nested one within another, the height
of the multipart biowaste container is less than three inches.
According to another embodiment of the present invention, the
anti-splash container, the dual purpose lid container, and the
supplementary container have an individual wall height that is less
than 1.5 inches and a total overall height when nested for shipping
of less then 2 inches.
[0020] These and other objects and features of the present
invention will become more fully apparent from the following
description and appended claims, or may be learned by the practice
of the invention as set forth hereinafter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0030] FIG. 1 illustrates the multipart biowaste container 1
including an anti-splash container 10, a dual purpose lid container
12, and a supplementary container 14. The multipart biowaste
container is configured to provide a receptacle for blood, tissue,
and other biological materials that result from a surgical
procedure being performed. Additionally, the multipart biowaste
container 1 is designed to allow safe and effective disposal of the
materials contained therein. Anti-splash container 10 is configured
to allow the introduction of blood, tissues, or other biological
wastes while preventing the inadvertent splashing or spillage of
such materials once introduced into anti-splash container 10.
[0031] Dual purpose lid container 12 provides an additional
receptacle for receiving blood, tissues, or other biological
materials. Because dual purpose lid container 12 does not include
an anti-splash component or other covering, larger biological
materials or implements that may be used during the course of the
procedure can easily be placed in dual purpose lid container 12. At
the conclusion of the procedure, dual purpose lid container 12
provides a secure lid for covering anti-splash container 10. Once
dual purpose lid container 12 is securely secured to the top of
anti-splash container 10, dual purpose lid container 12 can then be
disposed of without spillage of fluids from anti-splash container
10.
[0032] Supplementary container 14 provides yet another receptacle
for receiving blood, tissues, or fluids during the course of the
surgical procedure. The use of anti-splash container 10, dual
purpose lid container 12, and supplementary container 14 provide
the ability to hold a significant total volume of blood, tissues,
or other biological materials that may be produced during the
course of the procedure. By providing three separate biowaste
containers, multipart biowaste container 1 also allows individual
anti-splash container 10, dual purpose lid container 12, and a
supplementary container 14 to be placed in strategic locations in
the surgical work area. The ability to strategically locate
containers 10, 12, and 14 facilitates simultaneous operation of
different aspects of the procedure being performed. In the
illustrated embodiment, anti-splash container 10, dual purpose lid
container 12, and supplementary container 14 all have a low profile
relative to their overall size, to minimize spilling, tipping, or
other interference with containers 10, 12, and 14 during the course
of the surgical procedure. During shipping and storage of the
multipart biowaste container 1, anti-splash container 10, dual
purpose lid container 12, and supplementary container 14 are nested
within one another providing a single item having a relatively low
profile and overall efficient storage volume.
[0033] In the illustrated embodiment, anti-splash container 10
includes a basin 16 and a splash guard 18. Basin 16 is adapted to
receive and contain blood, fluids, and other biological materials
that are introduced to anti-splash container 10. Basin 16 includes
a multipart wall 17 and vent channels 23. Multipart wall 17 has a
relief surface configured to nest with one or both of dual purpose
lid container 12 and supplementary container 14. Multipart wall 17
has a height of less than two inches providing an overall low
profile relative to the overall size of anti-splash container 10.
This minimizes spillage or tipping of anti-splash container 10
during use. Vent channels 23 provide venting to the interior of
basin 16 allowing the passage of air from the volume of basin 16 as
blood, fluids, and other materials are introduced into basin 16.
Additionally, the configuration of vent channels 23 minimizes the
passage of fluids or other biological materials from the interior
basin the exterior of basin 16.
[0034] Splash guard 18 is configured to nest within the rim of
basin 16 in a simple and secure manner. Splash guard 18 provides a
covering to the interior of basin 16. Splash guard 18 allows the
introduction of blood, fluids, and other biological materials into
basin 16 while minimizing splashing or the inadvertent spilling of
materials within basin 16. Splash guard 18 includes an input site
20, a slit valve 21, and flow channels 22a, b, c, d. Input site 20
comprises a bore in the middle of the plastic material forming
splash guard 18. Input site allows for the introduction of fluid
and materials through the plastic guard portion of splash guard 18
and into the volume of basin 16.
[0035] Slit valve 21 is secured over the top of input site 20. Slit
valve 21 permits the introduction of blood, fluids, and other
biological materials through input site 20 while controlling
inadvertent splashing or spillage of materials from the volume of
basin 16. In the illustrated embodiment, slit valve 21 comprises a
compressible foam material which allows the passage of air while
minimizing the inadvertent flow of fluids from within the volume of
basin 16. For example, in a catheterization procedure, a catheter
is introduced through the slits of slit valve 21 and into the
volume of basin 16. When the opposing end of the catheter is
inserted into the patient, saline, blood, contrast media, or other
fluids which may be positioned in the catheter flow directly into
the volume of basin 16. Splash guard 18 and a corresponding slit
valve 21 minimize the splashing of such blood, fluids, or other
biological material to the external environment.
[0036] Flow channels 22a, b, c, d are provided at the four angular
ridges of splash guard 18. Flow channels 22a, b, c, d originate
adjacent the slit valve 21 and input site 20 and run in a funnel
type fashion to the comers of splash guard 18. Flow channels 22a,
b, c, d provide a contained and efficient mechanism for directing
the flow of fluids that contact the exterior splash guard 18 but
are not introduced into the volume of basin 16 through slit valve
21. Such blood, fluid, or other biological materials can flow along
the length of flow channels 22a, b, c, d and enter the volume of
basin 16 through corresponding vent channels 23.
[0037] As will be appreciated by those skilled in the art, a
variety of types and configurations of anti-splash containers can
be utilized without departing from the scope and spirit of the
present invention. For example, a valve member not comprising a
slit valve can be utilized in connection with the input site.
Additionally a valve formed from elastomeric or other deformable
materials can be utilized in connection with the input site. In
another embodiment, the flow channels correspond with a low
elevation portion of the splash guard such that the splash guard
facilitates funneling of fluids not introduced through the input
site. In another embodiment, the shape, size, and/or juxtaposition
of elements of the anti-splash container are varied.
[0038] Dual purpose lid container 12 is provided as an additional
receptacle for the containment of blood, tissues, or other
biological materials. Dual purpose lid container 12 includes a pour
spout 24, a waste basin 26, and absorbent pad 28. Waste basin 26 is
configured to receive and effectively hold biological materials
introduced into dual purpose lid container 12. Pour spout 24 is
provided at the corner of waste basin 26 to allow a practitioner to
safely and efficiently pour excess fluids collected in waste basin
gaffe 26 into a disposal receptacle or into anti-splash container
10. Absorbent pad 28 is provided at the inside bottom surface of
waste basin 26. Absorbent pad 28 absorbs blood, fluid, or other
biological materials which are introduced into dual purpose lid
container 12 to effectively contain such materials within dual
purpose lid container 12. According to one embodiment of the
present invention, absorbent pad 28 is imbued with chemical
properties which solidify, coagulate, or otherwise contain
biological waste materials (such as by forming a gel or other
acceptable material properties to contain such materials.)
According to one embodiment of the present invention, the absorbent
pad is imbued with Sodium Polyacrylate [sp?] or the equivalent.
[0039] Multipart wall 29 has an interior relief which is configured
to nest on the underside of anti-splash container 10. Nesting of
dual purpose lid 12 on anti-splash container 10 provides a minimal
overall size and volume of multipart biowaste container 1 during
shipping and storage of multipart biowaste container 1.
Additionally, the overall height of multipart wall 29 is less than
two inches, minimizing the potential for tipping or spillage of
dual purpose lid container 12.
[0040] Because dual purpose lid container 12 does not include a
splash guard, larger biological waste or materials imbued with
biological waste can be received by dual purpose lid container 12.
For example, a sponge utilized to absorb blood during the course of
the procedure may be temporally, or permanently placed in dual
purpose lid container 12. When the surgical procedure is completed,
any excess blood, fluid, or other biological waste not solidified
by absorbent pad 28 can be poured from waste basin 26 and into a
secondary receptacle such as anti-splash container 10. The dual
purpose lid container 12 can then be placed over the top and
securely fastened to anti-splash container 10 to secure the
biological waste during disposal of both anti-splash container 10
and dual purpose lid container 12.
[0041] The height of multipart wall 29 is designed to provide
clearance between absorbent pad 28 and splash guard 18 of
anti-splash container 10. When dual purpose lid container 12 is
securely fastened to the top of anti-splash container 10, dual
purpose lid container can accommodate splash guard 18 without
interference from absorbent pad 28, even when absorbent pad 28 is
saturated with blood, fluid, or other materials. The plurality of
grip members 30a, b, c, d are positioned at the comers of multipart
wall 17 to secure anti-splash container 10 into dual purpose lid
container 12 when dual purpose lid container 12 is nested on the
underside of anti-splash container 10.
[0042] Supplementary container 14 is provided as another receptacle
for biological waste in addition to anti-splash container 10, and
dual purpose lid container 12. Supplementary container 14 includes
a liquid basin 32 and a multipart wall 34. As with anti-splash
container 10 and dual purpose lid container 12, the multipart wall
34 of supplementary container 14 has sufficiently low profile to
minimize spilling or tipage of materials within supplementary
container 14.
[0043] Supplementary container 14 does not include an absorbent pad
as depicted with dual purpose lid container 12. This allows a
surgical staff to utilize supplementary container 14 for saline,
flushing fluids, or other liquids that may be used during the
course of the procedure. For example, in the event that a volume of
saline is used early in the procedure, when minimum amounts of
biological materials need to be disposed of, the surgical staff may
utilize supplementary container 14 as receptacle for such saline at
the early portions of the procedure. During later stages of the
procedure where more biological waste is produced and needs to be
disposed of, the surgical staff can utilize supplementary container
14 as a receptacle for such biological waste.
[0044] At the completion of the procedure, supplementary container
14 can be disposed of in connection with anti-splash container 10
and dual purpose lid container or separately as dictated by the
surgical procedure. The relief of multipart wall 34 of
supplementary container 14 is designed to nest on the underside of
dual purpose lid container 12 during shipping. This provides an
overall low profile design to optimize shipping and storing of the
multipart biowaste container 1.
[0045] As will be appreciated by those skilled in the art a variety
of types and configurations of multipart biowaste containers can be
utilized without departing from the scope and spirit of the present
invention. For example, in one embodiment, the multipart biowaste
container does not include a supplementary container but instead
utilizes only an anti-splash container and a dual purpose lid
container. In another embodiment, one or both of the supplementary
container and dual purpose lid container are configured to nest on
top of anti-splash container during shipping and storage of the
multipart biowaste container. In another embodiment, both the dual
purpose lid container and supplementary container include pour
spouts. In yet another embodiment, the supplementary container is
provided with an absorbent pad.
[0046] FIG. 2 illustrates multipart biowaste container 1 in which
anti-splash container 10, dual purpose container 12, and
supplementary container 14 are configured for shipping and storage
of the multipart biowaste container 1. In the illustrated
embodiment, anti-splash container is positioned on top of dual
purpose lid container 12 and supplementary container 14.
Positioning of anti-splash container 10 on top of the other
containers can be utilized due to the use and positioning of
anti-splash guard 18. In the illustrated embodiment, dual purpose
lid container 12 is nested beneath anti-splash container 10. The
primary visible portion of dual purpose lid container 12 when
nested with supplementary container 14 and anti-splash container is
limited to the outside rim of dual purpose lid container 12.
Supplementary container 14 is nested beneath dual purpose lid
container 12. In the illustrated embodiment, supplementary
container 14 is positioned such that bottom 70 of supplementary
container 14 provides the bottom contact surface for multipart
biowaste container 1.
[0047] Multipart wall 34 of supplementary container 14 provides the
bulk of the exposed wall surface of multipart biowaste container 1
when anti splash container 10, dual purpose lid container 12, and
supplementary container 14 are nested together for shipping and
storage purposes. In other words, the height of multipart wall 34
corresponds with the majority of the overall height of multipart
biowaste container 1 when configured for shipping and storage
purposes. In the illustrated embodiment, upper rim 36 of
anti-splash container 10 is positioned as the upper contact surface
of multipart biowaste container, when anti-splash container 10,
dual purpose lid container 12, and supplementary container 14 are
nested together for shipping and storage purposes.
[0048] In the illustrated embodiment, multipart wall 34 of
supplementary container 14 has an overall height of less than two
inches and multipart biowaste container 1 has an overall height of
less than 3 inches when anti-splash container 10, dual purpose lid
container 12, and supplementary container 14 are nested together
for shipping and storage purposes. In another embodiment, multipart
wall 34 of supplementary container 14 has an overall height of less
than 1.5 inches and multipart biowaste container 1 has an overall
height of less than two inches when anti-splash container 10, dual
purpose lid container 12, and supplementary container 14 are nested
together for shipping and storage purposes.
[0049] As will be appreciated by those skilled in the art, a
variety of types and configurations of multipart biowaste
containers can be utilized without departing from the scope and
spirit from the present invention. For example, in one embodiment
one or both of dual purpose lid container 12 and supplementary
container 14 are configured to be positioned on top of anti-splash
container 10 during shipping and storage. In another embodiment,
the splash guard 18 of the anti-splash container is configured to
be removed during shipping and storage of multipart biowaste
container. In another embodiment, the anti-splash container is
configured to be the bottom most container and nests beneath one or
both of the dual purpose lid container and the supplementary
container. In yet another embodiment, the multipart biowaste
container only utilizes two containers rather then three
containers.
[0050] FIG. 3 is a cross-sectional partial end view of anti-splash
container 10, dual purpose container 12, and supplementary
container 14 illustrating the relief surfaces allowing for nesting
and coorperative engagement between anti-splash container 10, dual
purpose lid container 12, and supplementary container 14. In the
illustrated embodiment anti-splash container 10 includes an upper
rim 36, an angular upper surface 39, an extension rim 40, an inner
wall 41, an inner rim 42, a lower vertical wall 44, and a bottom
46.
[0051] Upper rim 36 is provided as the upper most surface of
anti-splash container 10. Upper rim 36 is configured to contact a
portion of dual purpose lid container 12 when dual purpose lid
container 12 is cooperatively coupled to anti-splash container 10
to provide a lid for anti-splash container 10. Angular upper
surface 39 is positioned adjacent and to the outside of upper rim
36. Angular upper surface 39 is configured to allow for the
cooperative engagement between anti-splash container 10 and dual
purpose lid container 12. Extension rim 40 extends horizontally
from the volume of anti-splash container 10. Extension rim 40 abuts
against dual purpose lid container 12 when the dual purpose lid
container 12 is positioned over anti-splash container 10. Inner
wall 41 extends downward from upper rim 36 in an angular fashion.
The angular configuration of inner wall 41 secures splash guard 18
(not shown) in its correct position relative to the volume of basin
16.
[0052] Inner rim 42 extends horizontally from inner wall 41 in an
inward direction. Inner rim 42 provides a bottom contact surface
for splash guard 18 (not shown) securing the juxtaposition of
splash guard 18 relative to basin 16. Lower vertical wall 44
extends horizontally downward from inner rim 42. Lower vertical
wall 44 provides the volume of basin 16 for holding blood, fluid,
or other biological materials. Bottom 46 extends horizontally from
lower vertical wall 44 to provide the bottom surface of anti-splash
container 10. As will be appreciated by those skilled in the art, a
number of different types and configurations of multipart walls can
be utilized without departing from the scope and spirit of the
present invention.
[0053] Dual purpose lid container 12 is configured to nest on the
underside of anti-splash container 10 during shipping and storage
of the multipart biowaste container 1. In the illustrated
embodiment, dual purpose lid container includes an extension rim
50, a first upper angular surface 52, a second upper angular
surface 54, an inner rim 56, a lower vertical wall 58, and a bottom
59. Extension rim 50 is positioned as the upper surface of dual
purpose lid container 12. Extension rim 50 extends vertically
outward from the inner volume of dual purpose lid container 12.
Extension rim 50 is configured to contact extension rim 40 of the
anti-splash container when dual purpose lid container is positioned
over anti-splash container 10 in a lid configuration.
[0054] First upper angular surface 52 extends downward and at an
angle relative to extension rim 50. Second upper angular surface 54
extends downward and inward relative to first upper angular surface
52. The juxtaposition of first upper angular surface 52 and second
upper surface 54 are configured to fit and facilitate engagement
with angular upper surface 39 when dual purpose lid container 12 is
positioned over anti-splash container 10 in a lid configuration.
Inner rim 56 extends horizontally inward from second upper angular
surface 54. Inner rim 56 is configured to contact upper rim 36 of
anti-splash container 10 when dual purpose lid container 12 is
positioned over anti-splash container 10 in a lid configuration.
Lower vertical wall 58 extends downward from inner rim 56. Lower
vertical wall 58 is configured to be positioned adjacent lower
vertical wall 44 when dual purpose lid container is nested beneath
anti-splash container 10. Bottom 59 extends horizontally inward
from lower vertical wall 58.
[0055] Supplementary container 14 is configured to nest beneath
dual purpose lid container 12 when multipart biowaste container 1
is being shipped and/or stored. In the illustrated embodiment
supplementary container 14 includes an extension rim 60, a first
upper angular surface 62, a second upper angular surface 64, an
inner rim 66, a lower vertical wall 68, and a bottom 70. Extension
rim 60 is positioned as the upper surface of dual purpose lid
container 12. Extension rim 60 extends vertically outward from the
inner volume of dual purpose lid container 12.
[0056] First angular surface 62 extends downward and at an angle
relative to extension rim 60. Second angular surface 64 extends
downward and inward relative to first upper angular surface 62. The
juxtaposition of first upper angular surface 62 and second upper
surface 64 are configured to fit and make engagement with angular
upper surface 39 in the event that supplementary container 14 is
positioned over anti-splash container 10 in a lid configuration.
Inner rim 66 extends horizontally inward from second angular
surface 64. Inner rim 66 is configured to contact upper rim 36 of
anti-splash container 10 when supplementary container 14 is
positioned over anti-splash container 10 in a lid configuration.
Lower vertical wall 68 extends downward from inner rim 66. Lower
vertical wall 68 is configured to be positioned adjacent lower
vertical wall 44 when dual purpose lid container 12 is nested
beneath anti-splash container 10. Bottom 70 extends horizontally
inward from lower vertical wall 68.
[0057] In the illustrative embodiment supplementary container 14 is
configured to be optionally utilized with anti-splash container 10
in a lid configuration. In this embodiment, in the event that both
anti-splash container 10 and dual purpose lid container 12 are
substantially filled with biological waste, the dual purpose lid
container 12 can be disposed of and the supplementary container 14
can be utilized as a covering for the anti-splash container 10.
[0058] As will be appreciated by those skilled in the art, a
variety of types and configurations of multipart walls of
anti-splash container, dual purpose lid container, and
supplementary container can be utilized without departing from the
scope and spirit of the present invention. For example, in one
embodiment, the lower vertical walls of the anti-splash container,
dual purpose lid container, and supplementary container all are of
similar height allowing the containers to be nested within one
another. The upper angular surfaces of dual purpose lid container
and supplementary container are eliminated and a secondary
securement mechanism is provided to secure one or both of the dual
purpose lid container and the supplementary container relative to
the anti-splash container in a cover configuration.
[0059] FIG. 4 is a perspective view of the anti-splash container
according to one embodiment of the present invention. In the
illustrated embodiment, splash guard 18 is shown separated from
basin 16. Splash guard 18 is clear or transparent to allow a
practitioner to view the volume of materials positioned in basin
16. Splash guard 18 is configured to nest inside inner wall 41
while abutting against inner rim 42. Inner wall 41 slants slightly
inward to cooperatively secure splash guard 18 without requiring a
separate securement apparatus or adhesive materials.
[0060] In the illustrated embodiment, vent channels 23 are shown.
Vent channels 23 provide a passageway for air and materials to
facilitate passage of fluid into basin 16. In the illustrated
embodiment, vent channels 23 comprise a slot on the inside surface
of inner wall 41 and inner rim 42. This facilitates the passage not
only past the outside rim of splash guard 18, but also to/from the
volume of basin 16. Grip members 80a, b facilitate the cooperative
engagement of anti-splash container 10 with the dual purpose lid
container 12 and the supplementary container 14.
[0061] FIG. 5 is a bottom view of basin 16 of anti-splash container
10 according to one embodiment of the present invention. In the
illustrated embodiment, the adhesive pad 82 is secured to bottom 46
of basin 16. Adhesive pad 82 allows the surgical staff to secure
supplementary container 14 to a work surface, such as the operating
table, surgical instrument support surface, or the patient, so as
to minimize movement or tipping of anti-splash container 10 during
surgery. Adhesive pad 82, in combination with the low-profile of
anti-splash container 10, provide a safe and effective mechanism
for containing biological materials introduced into anti-splash
container 10 while preventing inadvertent spilling of the contents
of anti-splash container 10.
[0062] In the illustrated embodiment, adhesive pad 82 includes a
removable backing 84 and an adhesive layer 86. When a user is
preparing to utilize adhesive pad 82, the user grasps removable
backing 84 and pulls in a rearward direction. As removable backing
84 is pulled in rearward direction it separates from adhesive pad
82. Removable backing 84 maintains the adhesive properties of
adhesive layer 86 prior to placement of anti-splash container 10 on
the working surface. Once removable backing 84 is removed, adhesive
layer 86 is exposed and can be applied directly to the work surface
in which the practitioner desires to position anti-splash container
10.
[0063] As will be appreciated by those skilled in the art, a
variety of types and configurations of mechanisms for maintaining
the positioning of anti-splash container can be utilized without
departing from the scope and the spirit of the present invention.
For example, in one embodiment a hook and loop type device such as
Velcro.RTM. can be positioned on the bottom of the anti-splash
container. One of the hook and loop component members can be placed
on the work surface and the other can be placed on bottom of the
anti-splash container. The hook and loop members can then be mated
to secure the anti-splash container relative to the work surface.
In another embodiment, the bottom of the anti-splash container can
be textured or provided with other mechanical properties which
secure the positioning of the anti-splash container to minimize
tipping or spillage of the anti-splash container. As will
appreciated by those skilled in the art, an adhesive pad or other
acceptable alternative can be used with the dual purpose lid and
the supplementary container instead of, or in addition to, that
used with the anti-splash container.
[0064] FIG. 6 is a perspective view of the anti-splash container 10
and dual purpose lid container 12 illustrating the manner in which
materials can be poured from the dual purpose lid container 12 into
the anti-splash container 10. In the illustrated embodiment, a
volume of fluid 88 is positioned in dual purpose lid container 12.
For one or a variety of reasons a user may desire to empty the
volume of fluid 88 from dual purpose lid container 12 into
anti-splash container 10. For example, at the end of the procedure
the user may desire to position dual purpose lid container 12 over
anti-splash container 10 in a lid configuration as previously
discussed. Alternatively, the user may simply desire to consolidate
all biological waste in a single container at the end of the
procedure.
[0065] To drain the volume of fluid 88 from dual purpose lid
container 12 the user tilts dual purpose lid container 12 in an
angular fashion such that pour spout 24 is at a lower elevation
than the other corners of dual purpose lid container 12. As the
user tips dual purpose lid container 12, the volume of fluid
consolidates at the corner of the basin corresponding with pour
spout 24. As the user continues to tilt dual purpose lid container
12 the volume of fluid begins to flow through pour spout 24 to the
exterior of dual purpose lid container 12.
[0066] In the illustrated embodiment, the user has begun to tilt
dual purpose lid container 12. The user has simultaneously
positioned pour spout 24 inside slit valve 21 such that the pour
spout 24 has opened the slits of slit valve 21. The opening of slit
valve 21 allows the passage of the fluids flowing from pour spout
24. In other words, fluids pour directly from pour spout 24,
through slit valve 21, and into basin 16. This provides a simple
and effective mechanism for transferring fluids from dual purpose
lid container 12 into anti-splash container 10. Once the volume of
fluid 88 has been completely drained from dual purpose lid
container 12 into anti-splash container 10, dual purpose lid
container 12 can be positioned over anti-splash container 10 in a
lid-like fashion.
[0067] FIG. 7 illustrates the juxtaposition of dual purpose lid
container 12 and anti-splash container 10 when dual purpose lid
container 12 has been positioned over anti-splash container 10 in a
lid-like fashion. In the illustrated embodiment, dual purpose lid
container 12 has been turned upside down such that bottom 59 is
facing in an upwards direction. The extension rim 50 of dual
purpose lid container 12 is positioned directly in contact with
extension rim 40. Extension rim 50 extends outward a lesser amount
than extension rim 40 making it difficult for a user to
inadvertently grasp extension rim 50 and separate it from extension
rim 40. This provides an efficient and reliable securement between
dual purpose lid container 12 and anti-splash container 10.
[0068] First upper angular surface 52 and second upper angular
surface 54 are positioned adjacent extension rim 50. First upper
angular surface 52 and second upper angular surface 54 provide
proper engagement with angular upper surface 39 (not shown) of
anti-splash container 10. Inner rim 56 of dual purpose lid
container 12 is positioned in contact with upper rim 36 (not shown)
of dual purpose lid container 12. The overall height of anti-splash
container 10 in combination with dual purpose lid container 12 is
slightly less than the sum of the height of multipart wall 17 of
anti-splash container 10 and multipart wall 29 of dual purpose lid
container 12. This is due to the overlap and cooperative engagement
between first upper angular surface 52 second upper angular surface
54 of dual purpose lid container 12 and angular upper surface 39
(not shown) of anti-splash container 10.
[0069] FIG. 8 is a top view of an anti-splash container 90
according to an alternative embodiment of the present invention. In
the illustrated embodiment, anti-splash container 90 includes a
basin 92, a splash guard 94, slit valves 96a-c, and flow channels
98a-d. Basin 92 is utilized to provide a receptacle to receive and
contain blood, fluids, and other biological materials resulting
from the surgical procedure being performed. Splash guard 94 is
positioned over basin 92 to provide a cover to prevent spilling or
splashing of fluids and other materials positioned in basin 92.
[0070] Slit valves 96a-c are positioned on the upper surface of
splash guard 94. By providing a plurality of slit valves, a user
can deposit blood, fluid, or other materials into basin 92 in the
position or from the angle that is most convenient during the
procedure. For example, it may be easier to insert the catheter
through the slit valve 96a which is positioned centrally and at the
top of splash guard 94. However, it may be more advantageous to
pour fluids from dual purpose lid container 12, as depicted in FIG.
6 through one of the side slit valves 96b or 96c. Additionally,
utilizing a plurality of slit valves allows multiple aspects of the
procedure to be performed simultaneously. For example, one end of
the catheter may be positioned through slit valve 96a while a
practitioner is pouring fluid from dual purpose lid container 12
(not shown) through one of slit valves 96b-c. In the illustrated
embodiment, slit valves 96b, c are positioned at a slight angle
corresponding with the angle of the tapered side surfaces of splash
guard 94.
[0071] Flow channels 98a-d are positioned along the ridges flowing
from slit valve 96a to the corners of splash guard 94. Slit valves
96b-c are positioned between flow channels 98a, b, c, d such that
the positioning of slit valves 96b-c do not interfere with
operation of flow channels 98a, b, c, d. As will be appreciated by
those skilled in the art, a variety of types and configurations of
multipart biowaste containers can be utilized without departing
from the scope and spirit of the present invention. For example,
the anti-splash container can utilize only first and second slit
valves positioned on alternate sides of the splash guard. In
another embodiment, more than three waste containers are provided
as part of the multi-part biowaste container. For example, first
and second anti-splash containers can be nested within one another
with one of the splash guards being removable and replaceable in
preparation for a procedure to be performed. Additionally, first
and second dual purpose lid containers can be included to nest
beneath the first and second anti-splash containers providing four
total waste receptacles and two anti-splash container dual purpose
lid container combinations which can be disposed of separately
subsequent to the completion of the procedure.
[0072] The present invention may be embodied in other specific
forms without departing from its spirit or essential
characteristics. The described embodiments are to be considered in
all respects only as illustrative and not restrictive. The scope of
the invention is, therefore, indicated by the appended claims
rather than by the foregoing description. All changes which come
within the meaning and range of equivalency of the claims are to be
embraced within their scope.
