CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is a continuation-in-part of U.S. Ser. No.
13/134,498 filed on Jun. 9, 2011, DOW the entire contents of which
are hereby expressly incorporated by reference into the present
application. This application claims a benefit of priority under 35
USC .sctn.119 based on patent application 13/134,498 filed on Jun.
9, 2011.
BACKGROUND OF THE INVENTION
[0002] This invention relates generally to the field of devices for
securing or retaining catheters, IV tubes, drainage tubes or
similar medical lines to the skin of a patient at or near the point
of insertion, and more particularly relates to such devices
securing or retaining catheters and the like that extend generally
perpendicularly to the skin surface.
[0003] In many circumstances catheters or similar medical lines are
inserted percutaneously into the skin of a patient and must remain
in place for extended periods of time. To insure that the catheter
remains in place, it is known to create frameworks out of strips of
adhesive tape to secure the catheter tube to the patient's skin in
the proper orientation and to preclude accidental removal.
Catheters used with infants are particularly susceptible to
accidental dislodgement. In addition to the frameworks created out
of strips of adhesive tape by medical staff, dedicated catheter or
similar medical-line securement devices have been developed for
this purpose. Examples of such devices are seen in U.S. Pat. No.
3,138,158 to Gordon et al., U.S. Pat. No. 4,519,793 to Galindo,
U.S. Pat. No. 4,699,616 to Nowak et al., U.S. Pat. No. 4,767,411 to
Edmunds, U.S. Pat. No. 4,874,380 to Hesketh, U.S. Pat. No.

U.S. Pat. No. 5,232,453 to Plass et al., U.S. Pat. No. 5,370,627 to
Conway, and U.S. Pat. No. 6,866,652 to Bierman. Each of these
patented devices suffer drawbacks of one form or another, and it is
an object of this invention to provide a novel and improved
catheter securement device that addresses these drawbacks.
[0004] It is an object of this invention to provide a catheter
securement device that secures a catheter oriented generally
perpendicularly to skin of a patient, wherein the device is quickly
and easily applied to or removed from the patient and the
catheter.
SUMMARY OF THE INVENTION
[0005] The slotted catheter securement device comprises in general
a base member adhesively attachable to the skin of a patient and a
pair of bridging members connected to the base member whereby the
bridging members can be pivoted or folded upward to contact each
other, with at least one bridging member being provided with an
adhesive capable of adhering to the other bridging member and to
the portion of the catheter disposed between the two bridging
members. The bridging members are preferably defined as unattached
portions of a securing member selectively attached to a portion of
the base member, the base member and securing member being composed
of sheet material. Preferably, the securing member and the base
member have matching configurations such that both have an open
interior with a slot of greater width than the catheter diameter
extending from the interior through the body of the base and
securing members. This slotted structure allows the catheter
securement device to be positioned or removed with the catheter
already in place on the patient. Additionally, the securing member
and base member may have anchor pads that provide added stability.
The anchor pads extend perpendicular to, and in the same plane as
the securing member and base member.

DETAILED DESCRIPTION OF THE INVENTION
[0021] With reference to the drawings, embodiments of the invention
will now be described in detail with regard for the best mode and
the preferred embodiment. In general, the invention is a catheter
securement device adapted to secure and retain a percutaneously
inserted catheter or similar medical line, wherein the catheter is
oriented generally perpendicularly to the skin surface. The
catheter securement device is adhesively attached to the skin of
the patient and releasably secures the catheter. The catheter
securement device is particularly suited for use with newborns
having a catheter inserted into the umbilical stump, but the device
is not limited to this application. The term catheter as used
herein shall be taken as representing and encompassing any type of
percutaneous medical line, such as for example a catheter, an
intravenous (IV) tube, a drainage tube, etc. References herein to
the upper direction and the lower direction shall refer to the
direction away from the skin and the direction toward the skin,
respectively. The drawings are illustrative in nature, and in
particular the thickness dimension of the base member, securing
member and various adhesive layers are not to scale, the adhesive
layer thicknesses in certain figures being exaggerated relative to
the thicknesses of the base and sheet members for clarity
purposes.
[0022] The catheter securement device 10 comprises a base member 11
selectively joined to a securing member 21, as best seen in FIG. 4.
Both the base member 11 and the securing member 21 are composed of
flexible sheet material, such that each is relatively thin in
vertical cross-section. The base member 11 is adapted for adhesion
to the skin 91 of a patient and may be composed for example of a
medical grade adhesive bandage material, such as a polymer film
provided with a layer of adhesive, or a self-adhering material such
as a hydrocolloid patch, whereby the base member 11 can be applied
to the skin 91, will remain adhered for a suitable time period and
then easily removed. The base member 11 comprises an upper surface
12, a lower surface 13, an internal edge 14 and an external edge
15. The base member 11 internal edge 14 defines an interior opening
61. A slot 62 extends from the interior opening 61 completely
through and across the body of the base member 11. Preferably the
internal edge 14 and the external edge 15 are circular in
configuration as shown, such that the base member 11 is generally
C-shaped and the interior opening 61 is generally circular,
Additionally, the internal edge 14 and the external edge 15 may
feature anchor pads, for instance internal anchor pads 72a, 72b and
an external anchor pad 70a, 70b as shown in FIG. 8. These anchor
pads 70a, 70b, 72a, 72b extend generally perpendicularly away from
the internal edge 14 and external edge 15, respectively, along the
same plane as the base member 11. As shown, the anchor pads 70a,
70b, 72a, 72b are of a generally rectangular shape with rounded
edges. Other tabbed configurations could also be used. The anchor
pads 70a, 70b, 72a, 72b increase the surface area with which the
base member 11 contacts the patient's skin 91. As a result, the
base member 11 is more securely attached to the patient's skin 91.
This helps to prevent the base member 11 from pulling away from the
patient's skin 91 when the securement device is in use. As
illustrated, two internal anchor pads 72a, 72b and two external
anchor pads 72a, 72b are provided, although other configurations
could be used to achieve the same purpose. Alternatively, the
general configuration of the base member 11 could be oval,
rectangular or any other configuration.
[0023] Preferably the configuration of the securing member 21
matches that of the base member 11, such that the securing member
21 is likewise generally C-shaped. The securing member 21 may also
have internal anchor pads 72a, 72b and external anchor pads 70a,
70b as shown in FIGS. 10-15. The securing member 21 may be composed
of a flexible material suitable tar use in medical applications,
such as a tape, polymer or fabric material, and must possess
sufficient strength such that movement of the catheter 92 will be
suitably restricted, when the device is in use. The securing member
21 comprises an upper surface 22, a lower surface 23, an internal
edge 24 and an external edge 25. The internal edge 24 of the
securing member 21 also preferably defines the interior opening 61,
and slot 62 extends from the interior opening 61 completely through
and across the body of the securing member 21.
[0024] The base member 11 and securing member 21 are selectively
joined in a co-planar relationship, the junction being
non-coextensive. A mounting adhesive layer 51 is applied to
opposing sides of the either the base member upper surface 12 or
the securing member lower surface 23, preferably in the shape of a
strip extending across the interior opening 61, such that a portion
of the mounting adhesive layer 51 is on one side of the opening 61
and a portion of the mounting adhesive layer 51 is on the opposite
side of the opening 61. The mounting adhesive layer 51 is
preferably oriented at an angle of between about 20 to 60 degrees
relative to the slot 62, with an angle of about 35 degrees being
most preferable. The width of the mounting adhesive layer 51 is
preferably sized such that it does not encompass the slot 62. Any
adhesive material suitable for use in medical applications and
capable of bonding the base member 11 and securing member 21 may be
utilized. Alternatively, other joining methodologies such as heat
bonding, stitching, etc. may be used.
[0025] In this manner the securing member 21 is divided into at
least four defined segments, two of the segments being disposed on
opposite sides of the interior opening 61 and being segments
wherein the securing member 21 is joined to the base member 11, and
two of the segments likewise disposed on opposite sides of the
interior opening 61 and being segments that are not coextensively
joined to the base member 11. These latter segments are a first
bridging member 31 and a second bridging member 41. First bridging
member 31 comprises an attached end 32 that operates in a
hinge-like manner and a free end 33, with free end 33 abutting slot
62. Second bridging member 41 comprises a first attached end 42 and
a second attached end 43, both of which operate in a hinge-like
manner. An external anchor pad 70a and internal anchor pad 72a may
be located where the attached end 32 of the first bridging member
31 and the first attached end 42 of second bridging member 41 meet.
This is often helpful as this point can be subject to heightened
levels or pressure or stress. With this structure, the first
bridging member 31 is a flap-like member that is free to fold away
and upward from the base member 11 toward the center of the
catheter securement device 10. Likewise, the second bridging member
41 is a flap-like member that is flee to fold away and upward from
the base member 11 toward the center of the catheter securement
device 10, as shown in FIGS. 5, 6 and 15.
[0026] At least one of the upper surfaces 22 of the first and
second bridging members 31 and 41, and preferably both of the upper
surfaces 22, are provided with a securing adhesive layer 52 capable
of joining the first and second budging members 31 and 41 in a
releasable manner with the catheter 92 secured therebetween. Any
adhesive suitable for use in medical applications that possesses
the requisite characteristics of being able to securely yet
releasably join the two bridging members 31 can be utilized.
Preferably, a silicone-based adhesive or silicone-compatible
adhesive is utilized, since it is also desirable that the securing
adhesive layer 52 also adhere to the catheter 92 itself. The
adhesive layer 52 is not required to fully extend to the tip of the
free end 33, as shown in FIG. 7. In certain embodiments, as also
illustrated in FIG. 7, it may be necessary to provide a base,
adhesive layer 53 between the securing adhesive layer 52 and the
bridging members 31 and 41, such as for example when a particular
adhesive chosen for the securing adhesive layer 52 is not suitable
for adhesion to the material of choice for the securing member
21.
[0027] The catheter securement device 10 is preferably packaged
with a lower release liner member 80 and an upper release liner
member 82, as shown in FIGS. 8-15 and as well known in the art.
With the catheter 92 properly inserted and any lower release liner
member 80 removed from the lower surface 13 of the base member 11,
the catheter securement device 10 is properly positioned on the
patient encircling the catheter 92 by advancing the device such
that catheter 92 passes through slot 62. The base member 11 is then
adhered to the patient's skin 91 with the catheter 92 centered in
the interior opening 61. The upper release liner member 82 is then
removed to expose the securing adhesive layer 52 on one or both of
the bridging members 31 and 41 as shown in FIGS. 12-15. The
bridging, members 31 and 41 are then folded upward and together to
secure the catheter 92 in between. As seen in FIGS. 6 and 15, the
combination of the first and second bridging members 31 and 41
creates a generally stiff securing bridge connected to the base
member 11, the bridge having three legs formed by the attached end
32 of the first bridging member 31 and the first and second
attached ends 42 and 43 of second bridging member 41. Free end 33
of first bridging member 31 by necessity extends past the catheter
92 a sufficient distance to be secured to the second bridging
member 41, and further provides the means for separating the
bridging members 31 and 41, since the free end 33 can be grasped to
pull the first bridging member 31 from the second bridging member
41 to release the catheter 92.
[0028] For example only and with the express intention of not being
limiting in any manner, an embodiment of the catheter securement of
suitable size based on a circular configuration may have an
external radius of approximately 22 mm and an internal radius
defining the interior opening 61 of approximately 12 mm. The slot
62 may have a width of approximately 3 mm the width of the mounting
adhesive layer 51 may be approximately 8 mm and the width of the
securing adhesive layer 52 on each bridging member 31 and 41 may be
approximately 10 mm.
[0029] It is understood and contemplated that equivalents and
substitutions for certain elements and structures set forth above
may be obvious to one of ordinary skill in the art, and therefore
the true scope and definition of the invention is to be as set
forth in the following claims.
