UNIVERSAL FLUID CONTAINER ENCLOSURE SYSTEMS
Abstract
Various embodiments are generally directed to fluid container
enclosure systems that couple with a fluid container and enable
different systems, such as endoscopic systems, to access the
contents of the fluid container, such as via a tubing set. The
enclosure systems are configured to fit a wide range of fluid
container necks, ports, or other openings, including various
opening dimensions and thread finishes. In one embodiment, an
enclosure system may include a plug having a sleeve extending
therefrom. The plug may be deformed manually or via a plunger
system to reduce the outer dimension thereof to fit the plug in the
neck of a fluid container. Once the plug is arranged within the
neck, the sleeve may be folded down over an outer surface of the
neck to form or reinforce a seal between the enclosure system and
the neck of the fluid container. Other embodiments are
described.

Description
PRIORITY
[0001] The present application claims the benefit of priority under
35 U.S.C. .sctn. 119 to U.S. Provisional Application Ser. Nos.
63/084,274, 63/084,284, 63/084,292, and 63/084,297, each filed Sep.
28, 2020, the disclosures of which are incorporated herein by
reference in their entirety.
FIELD
[0002] The present disclosure relates generally to enclosures for
fluid containers. In particular, the present disclosure relates to
universal fluid container enclosures for endoscopic systems.
BACKGROUND
[0003] Endoscopy procedures that use typical endoscopes for both
therapeutic and diagnostic cases usually have some common
functionalities available to an operator. One of the common
functionalities includes the ability to insufflate a patient by
passing a fluid, such as air or carbon dioxide, through the
endoscope in a controlled manner into a target luminal space.
Another of the common functionalities includes the ability to flush
water across the imaging lens to clear the field of view. Yet
another of the common functionalities includes the ability to
irrigate the lumen to clean surfaces and aid in flushing/suctioning
debris during a procedure. Oftentimes, these common
functionalities, among others, are facilitated by one or more fluid
containers and/or fluid sources. For example, an air pump or carbon
dioxide source for insufflation, a water bottle for lens cleaning,
and/or a sterile water bottle for irrigation. In some cases, a
hybrid tubing set may be used for both lens cleaning and irrigation
from a sterile water bottle. The one or more fluid containers
and/or sources, each potentially with a different size and/or
configuration, must be attached to the tubing set of the endoscope.
It is with all of the above considerations in mind that the
improvements of the present disclosure may be useful.

DETAILED DESCRIPTION
[0051] The following Detailed Description should be read with
reference to the drawings, which depict illustrative embodiments.
It is to be understood that the present disclosure is not limited
to the particular embodiments described, as such may vary. All
apparatuses and systems and methods discussed herein are examples
of apparatuses and/or systems and/or methods implemented in
accordance with one or more principles of the present disclosure.
Each example of an embodiment is provided by way of explanation and
is not the only way to implement these principles but are merely
examples. Thus, references to elements or structures or features in
the drawings must be appreciated as references to examples of
embodiments of the present disclosure, and should not be understood
as limiting the present disclosure to the specific elements,
structures, or features illustrated. Other examples of manners of
implementing the disclosed principles will occur to a person of
ordinary skill in the art upon reading the present disclosure. It
will be apparent to those skilled in the art that various
modifications and variations can be made in the present disclosure
without departing from the scope or spirit of the present subject
matter. For instance, features illustrated or described as part of
one embodiment can be used with another embodiment to yield a still
further embodiment. Thus, it is intended that the present subject
matter covers such modifications and variations as come within the
scope of the appended claims and their equivalents.
[0052] The described technologies are generally directed to fluid
container enclosures configured to be coupled to a fluid container,
for example, to seal the fluid container while enabling access to
the contents of the fluid container, such as from an endoscopic
system via a tubing set. A fluid container may be or may include a
bottle or reservoir (see for example, reservoir 270). The fluid
container enclosures may be configured as a cap, lid, or other
enclosure component capable of sealing a fluid container. In some
embodiments, the fluid container enclosures may include openings,
lumens, holes, or other elements capable of allowing tubing access
to the contents of the fluid container while maintaining a seal.
Fluid container enclosures according to some embodiments are
configured to operate with fluid containers of various properties,
such as size, neck configuration, thread configuration, and/or the
like. Accordingly, fluid container enclosures according to some
embodiments may operate as universal enclosures that are able to be
used with a wide array of fluid container configurations, including
fluid contains made by different manufacturers and fluid containers
having different shapes, sizes, neck configurations, and/or the
like.
[0053] Some challenges in coupling with a fluid container and
gaining access to the contents of the fluid container may include
having a fluid container enclosure that is compatible with the
fluid container. For example, a fluid container enclosure may
include a screw cap with one or more tubes extending therethrough.
In such examples, the screw cap may couple to corresponding threads
on a neck of the fluid container with the one or more tubes
extending therethrough enabling the endoscopic system to access the
contents of the fluid container. However, there are many different
types of fluid container manufacturers that offer different fluid
container designs. Further, manufacturers may offer different fluid
container designs and/or periodically change or update fluid
container designs. For instance, manufacturers may offer designs
with different thread patterns or neck sizes around the world based
on regional preferences or demands. This presents a challenge for
manufacturers of tubing sets by requiring them to offer multiple
products with customized fluid container enclosures for each
design. Further, product acquisition and stocking by health care
facilities is complicated by necessitating that they ensure that
tubing sets have a fluid container enclosure that is compatible
with an available fluid container.
[0054] Accordingly, various embodiments of the present disclosure
include fluid container enclosures that widen the scope of
compatibility to a variety of different fluid container designs. In
many embodiments, one or more fluid container enclosures of the
present disclosure may provide an efficient, safe, and effective
way to couple with and gain access to the contents of a multitude
of fluid container designs. Enabling fluid container enclosures to
be compatible with different fluid container designs allows
manufacturers of tubing sets to offer products that are more
adaptable and appeal to a broader market. Further, enabling fluid
container enclosures to be compatible with different fluid
container designs can simplify product acquisition and stocking by
health care facilities.
[0055] For example, enclosure systems according to some embodiments
may be used with a wide variety of fluid container opening or neck
dimensions, such as an opening diameter and/or thread configuration
(for instance, Glass Packaging Institute (GPI) thread finish or "H"
dimension). In some embodiments, an enclosure system may include a
cap capable of being used to seal a fluid container having an
opening size of about 0.5 centimeters (cm), about 1 cm, about 2 cm,
about 3 cm, about 4 cm, about 5 cm, about 10 cm, about 20 cm, and
any value or range between any two of these values (including
endpoints). In some embodiments, an enclosure system may include a
cap capable of being used to seal a fluid container having a GPI
thread finish of 350, 400, 410, 415, 425, 430, 450, and any value
or range between any two of these values (including endpoints). The
described embodiments may provide additional advantages that would
be known to those of skill in the art.
[0056] It may be understood that the disclosure included herein is
exemplary and explanatory only and is not restrictive. As used
herein, the terms "comprises," "comprising," or any other variation
thereof, are intended to cover a non-exclusive inclusion, such that
a process, method, article, or apparatus that comprises a list of
elements does not include only those elements, but may include
other elements not expressly listed or inherent to such process,
method, article, or apparatus. The term "exemplary" is used in the
sense of "example," rather than "ideal." Although endoscopes and
endoscopic systems are referenced herein, reference to endoscopes,
endoscopic systems, or endoscopy should not be construed as
limiting the possible applications of the disclosed features. For
example, the disclosed features may be used in conjunction with
duodenoscopes, bronchoscopes, ureteroscopes, colonoscopes,
catheters, diagnostic or therapeutic tools or devices, or other
types of medical devices or systems.
[0057] Reference is now made to the drawings, wherein like
reference numerals are used to refer to like elements throughout.
In the following description, for purpose of explanation, numerous
specific details are set forth in order to provide a thorough
understanding thereof. It may be evident, however, that the novel
embodiments can be practiced without these specific details. In
other instances, well known structures and devices are shown in
block diagram form to facilitate a description thereof. The
intention is to cover all modification, equivalents, and
alternatives within the scope of the claims.
[0058] With reference to FIGS. 1-2, an exemplary endoscope 100 and
system 200 is depicted that may comprise an elongated shaft 100a
that is inserted into a patient. A light source 205 feeds
illumination light to a distal portion 100b of the endoscope 100,
which may house an imager (e.g., CCD or CMOS imager) (not shown).
The light source 205 (e.g., lamp) is housed in a video processing
unit 210 that processes signals that are input from the imager and
outputs processed video signals to a video monitor (not shown) for
viewing. The video processing unit 210 also serves as a component
of an air/water feed circuit by housing a pressurizing pump 215,
such as an air feed pump, in the unit.
[0059] The endoscope shaft 100a may include a distal tip 100c
provided at the distal portion 100b of the shaft 100a and a
flexible bending portion 105 proximal to the distal tip 100c. The
flexible bending portion 105 may include an articulation joint (not
shown) to assist with steering the distal tip 100c. On an end face
100d of the distal tip of the endoscope 100 is a gas/lens wash
nozzle 220 for supplying gas to insufflate the interior of the
patient at the treatment area and for supplying water to wash a
lens covering the imager. An irrigation opening 225 in the end face
100d supplies irrigation fluid to the treatment area of the
patient. Illumination windows (not shown) that convey illumination
light to the treatment area, and an opening 230 to a working
channel 235 extending along the shaft 100a for passing tools to the
treatment area, also may be included on the face 100d of the distal
tip 100c. The working channel 235 extends along the shaft 100a to a
proximal channel opening 110 positioned distal to an operating
handle 115 of the endoscope 100. A biopsy valve 120 may be utilized
to seal the channel opening 110 against unwanted fluid egress.
[0060] The operating handle 115 may be provided with knobs 125 for
providing remote 4-way steering of the distal tip via wires
connected to the articulation joint in the bendable flexible
portion 105 (e.g., one knob controls up-down steering and another
knob control for left-right steering). A plurality of video
switches 130 for remotely operating the video processing unit 210
may be arranged on a proximal end side of the handle 115. In
addition, the handle is provided with dual valve wells 135 that
receive a gas/water valve 140 for operating an insufflating gas and
lens water feed operation. A gas supply line 240a and a lens wash
supply line 245a run distally from the gas/water valve 140 along
the shaft 100a and converge at the distal tip 100c proximal to the
gas/wash nozzle 220 (FIG. 2). The other valve well 135 receives a
suction valve 145 for operating a suction operation. A suction
supply line 250a runs distally from the suction valve 145 along the
shaft 100a to a junction point in fluid communication with the
working channel 235 of the endoscope 100.
[0061] The operating handle 115 is electrically and fluidly
connected to the video processing unit 210, via a flexible
umbilical 260 and connector portion 265 extending therebetween. The
flexible umbilical 260 has a gas (e.g., air or CO2) feed line 240b,
a lens wash feed line 245b, a suction feed line 250b, an irrigation
feed line 255b, a light guide (not shown), and an electrical signal
cable. The connector portion 265 when plugged into the video
processing unit 210 connects the light source 205 in the video
processing unit with the light guide. The light guide runs along
the umbilical 260 and the length of the endoscope shaft 100a to
transmit light to the distal tip 100c of the endoscope 100. The
connector portion 265 when plugged into the video processing unit
210 also connects the air pump 215 to the gas feed line 240b in the
umbilical 260.
[0062] A water reservoir 270 (e.g., water bottle) is fluidly
connected to the endoscope 100 through the connector portion 265
and the umbilical 260. A length of gas supply tubing 240c passes
from one end positioned in an air gap 275 between the top 280
(e.g., bottle cap or enclosure) of the reservoir 270 and the
remaining water 285 in the reservoir to a detachable gas/lens wash
connection 290 on the outside of the connector portion 265. The gas
feed line 240b from the umbilical 260 branches in the connector
portion 265 to fluidly communicate with the gas supply tubing 240c
at the detachable gas/lens wash connection 290, as well as the air
pump 215. A length of lens wash tubing 245c, with one end
positioned at the bottom of the reservoir 270, passes through the
top (e.g., a cap or enclosure) 280 of the reservoir 270 to the same
detachable connection 290 as the gas supply tubing 240c on the
connector portion 265. In other embodiments, the connections may be
separate and/or separated from each other. The connector portion
265 also has a detachable irrigation connection 293 for irrigation
supply tubing (not shown) running from a source of irrigation water
(not shown) to the irrigation feed line 255b in the umbilical 260.
In some embodiments, irrigation water is supplied via a pump (e.g.,
peristaltic pump) from a water source independent (not shown) from
the water reservoir 270. In other embodiments, the irrigation
supply tubing and lens wash tubing 245c may source water from the
same reservoir. The connector portion 265 may also include a
detachable suction connection 291 for suction feed line 250b and
suction supply line 250a fluidly connecting a vacuum source (e.g.,
hospital house suction) (not shown) to the umbilical 260 and
endoscope 100.
[0063] The gas feed line 240b and lens wash feed line 245b are
fluidly connected to the valve well 135 for the gas/water valve 140
and configured such that operation of the gas/water valve in the
well controls supply of gas or lens wash to the distal tip 100c of
the endoscope 100. The suction feed line 250b is fluidly connected
to the valve well 135 for the suction valve 145 and configured such
that operation of the suction valve in the well controls suction
applied to the working channel 235 of the endoscope 100.
[0064] Referring to FIG. 2, an exemplary operation of an endoscopic
system 200, including an endoscope such as endoscope 100 above, is
explained. Air from the air pump 215 in the video processing unit
210 is flowed through the connection portion 265 and branched to
the gas/water valve 140 on the operating handle 115 through the gas
feed line 240b in the umbilical 260, as well as through the gas
supply tubing 240c to the water reservoir 270 via the connection
290 on the connector portion 265. When the gas/water valve 140 is
in a neutral position, without the user's finger on the valve, air
is allowed to flow out of the valve to atmosphere. In a first
position, the user's finger is used to block the vent to
atmosphere. Gas is allowed to flow from the valve 140 down the gas
supply line 240a and out the distal tip 100c of the endoscope 100
in order to, for example, insufflate the treatment area of the
patient. When the gas/water valve 140 is pressed downward to a
second position, gas is blocked from exiting the valve, allowing
pressure of the air passing from the air pump 215 to rise in the
water reservoir 270. Pressurizing the water source forces water out
of the lens wash tubing 245c, through the connector portion 265,
umbilical 260, through the gas/water valve 140 and down the lens
wash supply line 245a, converging with the gas supply line 240a
prior to exiting the distal tip 100c of the endoscope 100 via the
gas/lens wash nozzle 220. Air pump pressure may be calibrated to
provide lens wash water at a relatively low flow rate compared to
the supply of irrigation water.
[0065] The volume of the flow rate of the lens wash is governed by
gas pressure in the water reservoir 270. When gas pressure begins
to drop in the water reservoir 270, as water is pushed out of the
reservoir 270 through the lens wash tubing 245c, the air pump 215
replaces lost air supply in the reservoir 270 to maintain a
substantially constant pressure, which in turn provides for a
substantially constant lens wash flow rate. In some embodiments, a
filter (not shown) may be placed in the path of the gas supply
tubing 240c to filter-out undesired contaminants or particulates
from passing into the water reservoir 270. In some embodiments,
outflow check valves or other 1-way valve configurations (not
shown) may be placed in the path of the lens wash supply tubing to
help prevent water from back-flowing into the reservoir 270 after
the water has passed the valve.
[0066] A relatively higher flow rate compared to lens wash is
typically required for irrigation water, since a primary use is to
clear the treatment area in the patient of debris that obstructs
the user's field of view. Irrigation is typically achieved with the
use of a pump (e.g., peristaltic pump), as described. In
embodiments with an independent water source for irrigation, tubing
placed in the bottom of a water source is passed through the top of
the water source and threaded through the head on the upstream side
of the pump. Tubing on the downstream side of the pump 255c is
connected to the irrigation feed line 255b in the umbilical 260 and
the irrigation supply line 255a endoscope 100 via the irrigation
connection 293 on the connector portion 265. When irrigation water
is required, fluid is pumped from the water source by operating the
irrigation pump, such as by depressing a footswitch (not shown),
and flows through the irrigation connection 293, through the
irrigation feed line 255b in the umbilical, and down the irrigation
supply line in the shaft 100a of the endoscope to the distal tip
100c. In order to equalize the pressure in the water source as
water is pumped out of the irrigation supply tubing, an air vent
(not shown) may be included in the top (e.g., a cap or enclosure)
280 of the water reservoir 270. The vent allows atmospheric air
into the water source preventing negative pressure build-up in the
water source, which could create a vacuum that suctions undesired
matter from the patient back through the endoscope toward the water
source. In some embodiments, outflow check valves or other 1-way
valve configurations (not shown), similar to the lens wash tubing
245c, may be placed in the path of the irrigation supply tubing to
help prevent back-flow into the reservoir after water has passed
the valve.
[0067] FIG. 3A and FIG. 3B illustrates various features of an
embodiment of an enclosure system according to the present
disclosure. In particular, FIG. 3A depicts a side perspective view
and FIG. 3B depicts a top view of a plug-based enclosure system 505
having a plug 510 with a first (inserted or anterior) end 512
arranged to be inserted into a fluid container (see, for example,
FIGS. 4A and 4B) and a second (non-inserted or posterior) end 513
having a flexible sleeve 520 extending therefrom. In some
embodiments, sleeve 520 may be hollow, for example, formed the same
or similar to a flexible cylinder.
[0068] In various embodiments, enclosure system 505 may be formed
as a single piece. For example, plug 510 may be formed of a first
material (for instance, rigid silicone) that transitions into
sleeve 520 (for instance, a more flexible form of silicone). In
other embodiments, enclosure system 505 may be formed of separate
plug 510 and sleeve 520 portions coupled together, for example, via
an adhesive, fastener, or other coupling component.
[0069] In various embodiments, plug 510 may be formed of a rigid
yet deformable material. In some embodiments, plug 510 may be
formed of a polymer, an elastomer, silicone, rubber, cork, a wax,
variations thereof, and/or combinations thereof. In various
embodiments, plug 510 may be formed of silicone. In some
embodiments, plug 510 may be formed of a rigid form of silicone,
for example, with a durometer scale of between about 55 A to about
100 A. Plug 510 may be deformed such that its diameter (for
example, outer diameter) decreases in order to fit within a neck
(or other inlet/outlet port) of a fluid container, such as a
bottle.
[0070] In exemplary embodiments, one or more holes or openings 511
may be formed in plug 510 to accommodate, for instance, tubing 550
configured to extend into the fluid container to access the
contents thereof. In some embodiments, openings 511 may include or
may be associated with a liner or insert configured to maintain the
size and/or shape of openings 511 when plug 510 is being deformed
to fit within a neck of a fluid container. For example, a rigid
material, including, without limitation, silicone or a polymer, may
be arranged within at least a portion of openings 511 to prevent or
reduce the deformation of openings 511. Accordingly, tubes 550
extending through openings 511 may not be closed off due to the
deformation of plug 510, allowing the flow of fluid and/or gas
from/to the fluid container.
[0071] In various embodiments, sleeve 520 may be formed of a
material capable of allowing sleeve 520 to be deformed to fold down
over the neck of the fluid container after plug 510 has been
installed (see, for example, state 552 of FIG. 4B). In this manner,
sleeve 520 may operate to provide or enhance the sealing properties
of enclosure system 505. In some embodiments, sleeve may be formed
of a polymer, an elastomer, silicone, rubber, variations thereof,
and/or combinations thereof. In various embodiments, sleeve 520 may
be formed of silicone. In some embodiments, sleeve 520 may be
formed of a highly-flexible form of silicone, for example, silicone
on a low-durometer scale (for instance, between about 500 to about
50 A).
[0072] In one embodiment, to install enclosure system 505 in a
fluid container, a user may apply pressure to a portion of plug
510, such as by squeezing plug 510 at or near first end 512, to
decrease a diameter of plug 510 to fit into the neck of the fluid
container. The user may move first end 512 into the neck of the
fluid container and remove the pressure to allow the diameter of
plug 510 at the deformed portion to expand to create a seal against
the inner walls or surfaces of the neck of the fluid container.
Enclosure system 505 may be further secured to the fluid container
by rolling sleeve 520 over at least a portion of the neck of the
fluid container. In some embodiments, the sizing and/or flexibility
of sleeve 520 may facilitate sleeve 520 tightly conforming and/or
locking with any threads on an outside surface of the neck of the
fluid container (for instance, regardless of the particular thread
size, shape, or other configuration).
[0073] FIG. 4A illustrates various features of an embodiment of an
enclosure system according to the present disclosure. As shown in
FIG. 4A, plug-based enclosure system 505 may include a plunger 530
having a plunger rod 533 extending axially through plug 510 and a
stem 534 for engaging fingers of a user when pressing down on
plunger rod 533. An anchor 531 may be arranged on first end 512 of
plug 510 to affix plunger rod 533 to plug 510. For example,
movement of plunger rod 533 may push or pull on first end 512 of
plug. In FIG. 4A, enclosure system 505 is depicted in an initial
inactive state prior to installation in a fluid container.
[0074] FIG. 4B illustrates various features of installation of the
enclosure system of FIG. 4A on a fluid container. As shown in step
550, applying a force to plunger 530, for instance, by pushing on
handle 532 (e.g., using a thumb of a user similar to using a
plunger of a syringe to expel fluid from the syringe), to move
plunger rod 533 in direction A while maintaining plug 510 in the
same or substantially the same position (for instance, through an
opposing force by fingers engaging stem 534) may cause plug 510
(and sleeve 520) to deform, for example, to stretch and become
longer and decrease an outer diameter of plug 510. Once deformed by
forcing plunger 530 to a sufficient diameter, plug 510 may be moved
into a neck 182 of a fluid container 180 (for example, a bottle).
Referring to step 551, once plug 510 is positioned as desired
within neck 182, the user may release the force on plunger 530,
causing plunger rod 533 to move in direction B (for example, as
deformed plug 510 attempts to move back to its original, relaxed
shape). The outer diameter of plug 510 expands, and an outer
surface of plug 510 may press against an inner surface of neck 182
to affix plug 510 within neck 182. In some embodiments, plug 510
may form a water-tight, gas-tight, hermetic, or other type of seal
with neck 182.
[0075] Referring to step 552, once plug 510 has expanded within
neck 182 and created a seal, the user can roll sleeve 520 over the
outer surface of neck 204, for example, to provide for additional
sealing and/or holding of enclosure system 505 and fluid container
180. In addition, enclosure system may allow a user to secure
enclosure system 505 via plunger 530 using one hand (for instance,
allowing the user to steady fluid container 180 bottle with their
other hand if desired).
[0076] In some embodiments, once installed, plunger 530 or plunger
rod 533 may be removed from plug 510. For example, plunger rod 533
may be threaded to mate with anchor 531. In another example,
plunger rod 533 may form snap-fit, friction fit, or other type of
removable physical connection with anchor 531. To remove an
installed plug 510, plunger rod 533 may be re-connected with anchor
531 and then pushed in direction A to reduce an outer diameter of
plug.
[0077] Although a plunger 530 is used in the illustrative example
depicted in FIG. 4B, embodiments are not so limited. For instance,
enclosure system 505 may use any type of component capable of
deforming plug 510 to fit within neck 182, for example, a
releasable and/or removable clamp, vise, sleeve, and/or the like.
In another instance, enclosure system 505 may not use a separate
component to deform plug, instead, for instance, relying on manual
pressure by a user to deform and/or push plug 510 into neck to an
adequate position.
[0078] FIGS. 5A and 5B illustrates an embodiment of an enclosure
system according to one or more embodiments of the present
disclosure. As shown in FIG. 5A, a clamp-based enclosure system 705
may include an enclosure 710 and a clamp 720. In some embodiments,
enclosure 710 may be or may include a tube or tube portion. In
various embodiments, enclosure 710 may be formed of a flexible
material, such as a polymer, silicone, an elastomer, polyvinyl
chloride (PVC), a polyolefin, polyethylene, polyurethane,
variations thereof, and/or combinations thereof. In various
embodiments, clamp 720 may include a spring-based clamp or clip
having handles 722 and a clamp (spring) portion 721. In general,
squeezing handles 722 together may cause clamp portion 721 to open
(for instance, increase an inner diameter of the spring), releasing
handles 722 may cause clamp portion to close (for instance,
decrease the inner diameter of the spring). In general, clamp 720
may be biased toward the closed position.
[0079] FIG. 5B depicts enclosure system 705 installed on a neck 182
of a fluid container 100. In some embodiments, the original cap or
other enclosure that comes with bottle would be removed and
replaced with enclosure 710 configured to be fed over at least a
portion of neck 182. Inside of the tube formed by enclosure 710,
tubing 750 may extend into fluid container 180 to allow tubing 750
to access the contents of fluid container 180. In some embodiments,
enclosure 710 may be sized to form a friction fit with neck 182. In
addition, clamp 720 may be arranged around a portion of enclosure
710 covering neck to secure or further secure enclosure 710 to neck
182 and/or to form or enhance a seal between enclosure 710 and neck
182.
[0080] To install enclosure system 705 on fluid container 180 as
depicted in FIG. 5B, enclosure 710 may be forced or otherwise
positioned around neck 182. Clamp 720 may be initially positioned
around neck 182 in an open configuration and enclosure 710 passed
down through enclosure, or clamp may be passed down along enclosure
710 from a top portion (e.g., distal from neck 182) to the bottom
portion of enclosure 710 that will be positioned around neck 182.
Once enclosure 710 is positioned around neck 182, the opening force
on clamp 720 may be released to cause clamp portion 721 to clamp
around enclosure 710 and neck 182.
[0081] Although a spring clamp is used in the example depicted in
FIGS. 5A and 5B, embodiments are not so limited. For instance,
various other clamp or clamp-like components may be used instead of
or in combination with claim 720, such as a hose clamp, a collar, a
barbell collar-like mechanism, a clip, and/or the like.
[0082] FIGS. 6A and 6B illustrate an embodiment of an enclosure
system according to the present disclosure. As shown in FIGS. 6A
and 6B, a ball bearing (or quick disconnect) based enclosure system
805 may include a set of ball bearings 811 arranged within an
enclosure 810, such as a flexible tube. For example, ball bearings
811 may be arranged within a wall of a tube forming enclosure 810.
The enclosure 810 may be fed over a neck 182 of a fluid container
180, with ball bearings 811 floating freely (or relatively freely)
over threads 184. Once enclosure 810 is in position over neck 182,
a sleeve 820 may be forced over enclosure 810, forcing ball
bearings 811 into a position that compresses them against neck 182.
In some embodiments, ball bearings 811 may be spaced so that ball
bearings are arranged between threads 184. In various embodiments,
enclosure 810 may be formed of a flexible material, such as a
polymer, silicone, an elastomer, polyvinyl chloride (PVC), a
polyolefin, polyethylene, polyurethane, variations thereof, and/or
combinations thereof.
[0083] In various embodiments, sleeve 820 may be biased to move in
direction C, for example, by a spring or other biasing element (not
shown). Accordingly, enclosure 810 may be pushed onto neck 182
while sleeve 820 is being held in position above enclosure. Once
enclosure 810 is in proper position about neck 182, sleeve 820 may
be released, causing sleeve 820 to move in direction C, over
enclosure 810 portion around neck 182. In this manner, enclosure
system 805 may have portions that act the same or similar to a
quick connect coupling, for instance, sleeve 820 may operate the
same or similar as a spring-biased female coupling component of a
quick connect coupling.
[0084] In some embodiments, tubing 850 may extend into fluid
container 180 through enclosure system 805 to allow tubing 850 to
access the contents of fluid container 180. For example, enclosure
system 805 may include a conduit 830 for providing a passage for
tubing 850 to extend into fluid container 180.
[0085] FIGS. 6C-6E illustrate an embodiment of an enclosure system
according to the present disclosure. As shown in FIGS. 6C and 6D, a
ball bearing-based enclosure system 855 may include an enclosure
860 configured to be positioned about neck 182 of fluid container
180. Enclosure 860 may be formed of a flexible material, including,
without limitation, a polymer, silicone, rubber, and combinations
thereof. In various embodiments, enclosure 860 may form a friction
fit with neck 182. In some embodiments, enclosure system 855 may
have a sleeve 850 biased in direction D, for instance, by a spring
or other biasing element. While enclosure 860 is being positioned
about neck 182 by a user, sleeve 850 may be held in a downward
position toward neck 182 against the biasing force.
[0086] Referring to FIG. 6D, when enclosure 860 is suitably
positioned about neck 182, sleeve 820 may be released, causing
sleeve to move in direction E. In some embodiments, sleeve 820 may
move a specified distance, for example, due to a stop or a
limitation of the biasing force. When sleeve 820 slides up in
direction E, an inner surface of sleeve 820 may engage ball
bearings 811 and force ball bearings to be seated in a groove 830
or other structure of a mating element 870. In some embodiments,
mating element 870 may be the same or similar to a male quick
connect or fast-action coupler element, for example, as depicted in
FIG. 6E. Tubing 850 may extend through mating element 870 into
container 180.
[0087] When enclosure system 805 is in the installed state,
enclosure 860 may form a seal with neck 182 alone or in combination
with tube 810 and/or mating element 870. Engagement of mating
element 870 via ball bearings 811 may operate to maintain the
coupling between enclosure system 855 and fluid container 802.
Pushing down on sleeve 820 (for example, in a direction toward
fluid container 180) may allow ball bearings 811 to unseat from
groove 830 to allow for release of enclosure system 855 from fluid
container 180.
[0088] FIG. 7A-7C illustrates an embodiment of an enclosure system
according to one or more embodiments of the present disclosure.
FIG. 7A shows an external view of a sheath-based enclosure system
905 that includes an enclosure, hood, or cap 910 configured to be
arranged about a neck 182 of a fluid container 180. In some
embodiments, cap 910 may have a conical or substantially conical
shape. In various embodiments, cap 910 may be biased to a given
inner diameter by an external semiflexible sheath that will give
under force while maintaining a constant radial pressure. Cap 910
may be configured to have one or more tubes 960 extend therethrough
to access contents of fluid container 180.
[0089] FIG. 7B depicts a sectional view of enclosure system 905
showing cap in an uninstalled state. As shown in FIG. 7B, cap 910
may include internal features, such as protrusions or a ridge 911
extending from an internal bottom or base portion of cap. For
example, in some embodiments, protrusions 911 may include one or
more hooks, teeth, or other elements extending from an internal
surface of cap 910. In various embodiments, protrusions 911 may be
configured to catch or otherwise engage distended features on the
external surface of neck 182, such as threads 184.
[0090] In some embodiments, cap 910 and/or protrusions 911 may be
formed of a flexible material, such as a polymer, rubber, silicone,
and/or the like. In various embodiments, protrusions could be any
material that is acceptable from a biocompatibility perspective
while maintaining the ability to adhere to the features on neck 182
of fluid container 180. In some embodiments, protrusions 911 may
extend circumferentially or substantially circumferentially around
an inner portion of cap, for instance, forming a ridge, boss, or
shoulder. In various embodiments, a ridge, a protrusion, or a
portion of protrusions 911 may be formed at a base or bottom
portion of cap 910. In other embodiments, a ridge, a protrusion, or
a portion of protrusions 911 may be formed further up the inner
side wall or surface of cap 910.
[0091] In various embodiments, a sealing material 920 may be
arranged on an underside of cap 910, for example, on upper top
and/or side surfaces of cap 910. In some embodiments, sealing
material 920 may be formed of various malleable materials, such as
a polymer, silicone, (malleable) wax, variations thereof,
combinations thereof, and/or the like. In various embodiments,
sealing material 920 may be formed of a low durometer polymer or
silicone, such as a material with a durometer scale of about 5 A to
about 50 A. In some embodiments, sealing material 920 may have a
stickiness or tackiness characteristic. In exemplary embodiments,
sealing material 920 may circumferentially fill a top portion of
cap 910 to create a seal when cap 910 is pressed onto neck 182
(see, for example, FIG. 7C).
[0092] Referring to FIG. 7C, to install cap 910 on neck 182, cap
910 may be pressed down onto neck 182 and/or ratcheted around neck
182. The flexible material of cap 910 may allow protrusions 911 to
expand outward from neck 182 to allow cap 910 to be pressed
downward onto neck 182. For example, cap 910 may be pushed down on
neck 182, expanding out beyond threads 184. Because protrusions 911
are biased toward neck 182, protrusions 911 may become seated
within grooves between threads 184 when in the area of grooves 188.
In some embodiments, the flexible material of cap 910 and shape of
protrusions 911 (for instance, a hook or hook-like shape) may allow
biased protrusions 911 to ride or ratchet around grooves formed
between threads 184 such that cap 910 may be rotated onto necks 104
of various shapes, dimensions, and other physical characteristics
by riding through the grooves between threads 184 to become seated
as depicted in FIG. 7C. Cap 910 may be pressed down and/or threaded
down around neck to allow sealing material 920 to form a seal with
neck. In some embodiments, cap 910 may be installed on neck 182 to
maintain a certain pressure, for example, a pressure required by
fluid container 180 during operation (for instance, about 8 psi to
move fluid out of fluid container 180).
[0093] Once cap 910 is installed, movement of cap 910 away from
fluid container 180 may be prevented due to engagement of
protrusions 911 with threads 102. In addition, sealing material 920
may act the same or similar to an adhesive, particularly a weak,
temporary adhesive, to affix cap 910 to neck 182 and form a
water-tight, gas-tight, or hermetic seal between cap 910 and neck
182.
[0094] The foregoing discussion has broad application and has been
presented for purposes of illustration and description and is not
intended to limit the disclosure to the form or forms disclosed
herein. It will be understood that various additions,
modifications, and substitutions may be made to embodiments
disclosed herein without departing from the concept, spirit, and
scope of the present disclosure. In particular, it will be clear to
those skilled in the art that principles of the present disclosure
may be embodied in other forms, structures, arrangements,
proportions, and with other elements, materials, and components,
without departing from the concept, spirit, or scope, or
characteristics thereof. For example, various features of the
disclosure are grouped together in one or more features,
embodiments, or configurations for the purpose of streamlining the
disclosure. However, it should be understood that various features
of the certain features, embodiments, or configurations of the
disclosure may be combined in alternate features, embodiments, or
configurations. While the disclosure is presented in terms of
embodiments, it should be appreciated that the various separate
features of the present subject matter need not all be present in
order to achieve at least some of the desired characteristics
and/or benefits of the present subject matter or such individual
features. One skilled in the art will appreciate that the
disclosure may be used with many modifications or modifications of
structure, arrangement, proportions, materials, components, and
otherwise, used in the practice of the disclosure, which are
particularly adapted to specific environments and operative
requirements without departing from the principles or spirit or
scope of the present disclosure. For example, elements shown as
integrally formed may be constructed of multiple parts or elements
shown as multiple parts may be integrally formed, the operation of
elements may be reversed or otherwise varied, the size or
dimensions of the elements may be varied. Similarly, while
operations or actions or procedures are described in a particular
order, this should not be understood as requiring such particular
order, or that all operations or actions or procedures are to be
performed, to achieve desirable results. Additionally, other
implementations are within the scope of the following claims. In
some cases, the actions recited in the claims can be performed in a
different order and still achieve desirable results. The presently
disclosed embodiments are therefore to be considered in all
respects as illustrative and not restrictive, the scope of the
claimed subject matter being indicated by the appended claims, and
not limited to the foregoing description or particular embodiments
or arrangements described or illustrated herein. In view of the
foregoing, individual features of any embodiment may be used and
can be claimed separately or in combination with features of that
embodiment or any other embodiment, the scope of the subject matter
being indicated by the appended claims, and not limited to the
foregoing description.
[0095] In the foregoing description and the following claims, the
following will be appreciated. The phrases "at least one", "one or
more", and "and/or", as used herein, are open-ended expressions
that are both conjunctive and disjunctive in operation. The terms
"a", "an", "the", "first", "second", etc., do not preclude a
plurality. For example, the term "a" or "an" entity, as used
herein, refers to one or more of that entity. As such, the terms
"a" (or "an"), "one or more" and "at least one" can be used
interchangeably herein. All directional references (e.g., proximal,
distal, upper, lower, upward, downward, left, right, lateral,
longitudinal, front, back, top, bottom, above, below, vertical,
horizontal, radial, axial, clockwise, counterclockwise, and/or the
like) are only used for identification purposes to aid the reader's
understanding of the present disclosure, and/or serve to
distinguish regions of the associated elements from one another,
and do not limit the associated element, particularly as to the
position, orientation, or use of this disclosure. Connection
references (e.g., attached, coupled, connected, and joined) are to
be construed broadly and may include intermediate members between a
collection of elements and relative movement between elements
unless otherwise indicated. As such, connection references do not
necessarily infer that two elements are directly connected and in
fixed relation to each other. Identification references (e.g.,
primary, secondary, first, second, third, fourth, etc.) are not
intended to connote importance or priority, but are used to
distinguish one feature from another. The following claims are
hereby incorporated into this Detailed Description by this
reference, with each claim standing on its own as a separate
embodiment of the present disclosure. Reference signs in the claims
are provided merely as a clarifying example and shall not be
construed as limiting the scope of the claims in any way.
[0096] The following claims are hereby incorporated into this
Detailed Description by this reference, with each claim standing on
its own as a separate embodiment of the present disclosure. In the
claims, the term "comprises/comprising" does not exclude the
presence of other elements or steps. Additionally, although
individual features may be included in different claims, these may
possibly advantageously be combined, and the inclusion in different
claims does not imply that a combination of features is not
feasible and/or advantageous. In addition, singular references do
not exclude a plurality. The terms "a", "an", "the", "first",
"second", etc., do not preclude a plurality. Reference signs in the
claims are provided merely as a clarifying example and shall not be
construed as limiting the scope of the claims in any way.
