Description
BACKGROUND OF THE INVENTION
[0001] This invention relates generally to the field of medical
devices referred to as catheter securement devices, a catheter
being defined herein to include a small diameter, flexible tube
that is inserted through a person's skin and into a vein to deliver
or remove fluids such as blood, saline solutions, medications, etc.
A catheter securement device typically comprises a flexible sheet
member adhesively adhered to The patient's skin, the device having
means to retain the catheter tubing or a catheter housing, often a
coupling or junction member for connecting one tube to another or
to multiple tubes, in a relatively stable manner such that it is
less likely for the catheter to be accidentally pulled from the
patient.
[0002] Catheter securement devices are often located a short
distance from the insertion site, such that the securement device
has a minimal or reduced effect in securing the catheter tube in
place at the actual insertion site. It is an object of this
invention to provide a catheter securement device that reduces the
likelihood of accidental dislodgement of the catheter by providing
a structure that allows the securement device to be located close
to or at the insertion site, the device being provided with a pair
of opposing notches in a pad member for better securement of the
catheter.
SUMMARY OF THE INVENTION
[0003] The invention is a catheter securement device adapted to be
adhesively adhered to the skin of a patient, the device comprising
a flexible sheet-like main body member, a lower adhesive layer
disposed on the underside of the main body member, an upper
adhesive layer disposed on the upper side of the main body member,
a flexible sheet, flap or strap catheter retention member mounted
to the upper side of the main body member by a portion of the upper
adhesive layer, the flexible retention member having a fixed end
and a releasable end, and a double notched catheter pad member also
mounted on the upper side of and extending across the main body
member, preferably utilizing the upper adhesive layer, the notches
being on opposite sides of the pad member, the retention member and
pad member are arranged such that the retention member overlays the
pad member, and the retention member is provided with at least one
and preferably a pair of opposing notches, one notch preferably
larger than the other, that correspond in position to the notches
in the pad member. The pad upper surface is provided with an
adhesive layer. Preferably the main body member is also provided
with a pair of notches corresponding to the notches in the pad
member.
[0004] The catheter securement device is adhered to the patient
such that a first notch is positioned adjacent or near the catheter
insertion site. The catheter is brought up through the first notch,
positioned transversely across the main body member, and then
positioned down through the second notch. The flexible retention
member is then brought over the catheter and secured, the retention
member pressing the catheter into an exposed portion of the pad
member upper surface adhesive layer. The retention member is
provided with a notch of greater size than the pad member first
notch to reduce pressure being applied to the catheter where it
extends from the skin. The flexible retention member may be
releasably fastened utilizing the upper adhesive layer, or the
flexible retention member may be held in closed position by a hook
assembly member, the hook assembly member and the retention member
combining to form a hook-and-loop-type fastener. The retention
member may also be formed of a transparent or translucent material
to enable visual inspection of the retained catheter. The pad
member is preferably composed of a foam material.

DETAILED DESCRIPTION OF THE INVENTION
[0009] With reference to the drawings, 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 that adheres to the skin of a patient having an epidural
catheter or similar small flexible tube member inserted
percutaneously, the securement device acting to secure and retain
the catheter to prevent or reduce movement near the insertion site
or occidental dislodgement of the catheter. The securement device
in general comprises a flexible, sheet-like main body member
capable of adhering to the skin of the patient, a double notched
pad member over which the catheter is bent, and releasable
retention member lo secure the catheter onto the main body
member.
[0010] The catheter securement device comprises a main body member
11. The main body member 11 is a flexible, thin, sheet-like member,
generally elongated preferably into a dogbone-style configuration
with two sides 41, preferably concave, and two ends 42, preferably
rounded, the main body member 11 being shorter in transverse or
lateral direction than in the longitudinal direction. The main body
member 11 is preferably formed of a synthetic fabric material.
[0011] A lower adhesive layer 12, preferably composed of a
hypoallergenic pressure sensitive adhesive (PSA), is disposed on
the underside of main body member 11, and most preferably covers
the entire underside of main body member 11. The lower adhesive
layer 12 is chosen from the class of adhesives which are suitable
to removably adhere the main body member 11 to the skin of the
patient.
[0012] An upper adhesive layer 13, also preferably composed of a
hypoallergenic pressure sensitive adhesive (PSA), is disposed on
the upper side of main body member 11, and preferably docs not
cover the entire upper surface of the main body member 11 such that
portions of the main body member 11 adjacent the ends 42 are not
covered with adhesive. Most preferably, the upper adhesive layer 13
extends completely across the central portion of the main body
member 11 in the transverse or lateral direction, i.e., from one
side 41 to the other side 41.
[0013] A catheter pad member 14 is adhered to the upper surface of
the main body member 11 completely across the central portion of
the main body member 11 utilizing a portion of the upper adhesive
layer 13. The pad member 14 is preferably composed of a
compressible synthetic foam material. The pad member 14 comprises
an upper surface 31, a lower surface 32 and a pair of opposing
exposed edges 33. The pad member 14 is mounted onto the main body
member 11 such that the pad exposed edges 33 are positioned at the
sides 41 of the main body member 11. The pad member 14 is wider and
longer than the main body member edge recess 17 and upper adhesive
edge recess 16, such that a portion of the upper adhesive layer 13
will adhere to the pad lower surface 32 along the three interior
edges of the pad member 14. The pad upper surface 31 is preferably
provided with an adhesive layer 34. The transverse width of the pad
member 14 is substantially equal to the transverse width of the
main body member 11.
[0014] The pad member 14 further comprises a pair of opposing
notches 35a and 35b disposed in the exposed edges 33 and extending
completely through the depth of the pad member 14 from the upper
surface 31 of the pad member 14 to the lower surface 32 of the pad
member 14. The notches 35a and 35b extend a short distance
transversely toward the interior of the pad member 14. Preferably
the notches 35a and 35b have a generally V-shaped or U-shaped open
interior, although other shapes such as circular, oblong, rounded,
etc. are suitable alternatives. The notches 35a and 35b are
preferably the same size and configuration, but may differ. A first
notch 35a is adapted to receive or cradle the catheter 99 extending
upwardly from the insertion site 98 and bent transversely across
the pad member 14, while the second notch 35b is adapted to provide
for a downward slope to the portion of the catheter 99 extending
from the opposite exposed edge 33 of the pad member 14.
[0015] Most preferably the main body member 11 is also provided
with a pair of opposing notches 15a and 15b corresponding in
location to the pad member notches 35. The main body notches 15a
and 15b are preferably generally the same size and configuration as
the pad member notches 35a and 35b, but may also be of different
size and shape.
[0016] Connected to the main body 11 by a portion of the upper
adhesive layer 13 is a thin, flexible catheter retention member 21
in the form of a sheet, flap or strap. The retention member 21 has
a fixed end 25 and a releasable end 26, the retention member 21
being positioned such that in a closed position it overlaps
catheter pad member 14. The retention member 21 preferably is
shorter in the longitudinal direction that the main body member 11
and preferably is generally equal in width to the main body member
11 at corresponding points so as to match the peripheral
configuration. One side of the retention member 21 is provided with
a notch or recess 22a corresponding in location to the pad member
first notch 35a. the retention notch 22a preferably being of
greater size than the pad member first notch 35a. Most preferably,
the other side of the retention member 21 is provided with a second
notch or recess 22b, corresponding in location to the second pad
member notch 35b.
[0017] The catheter retention member 21 may also be provided with a
tab member 23 on its releasable end 26 for easier closing and
opening. The retention member 21 is preferably composed of a
synthetic fabric material, and in alternative embodiments the
retention member 21 may have a transparent window or be made of
transparent material in order to provide visual access to the
retained catheter 99 without need for releasing the retention
member 21.
[0018] In the embodiment as depicted, the catheter securement
device is further provided with a hook assembly member 24 mounted
onto the main body member II by a portion of the upper adhesive
layer 13. The hook assembly member 24 is positioned on the opposite
side of the pad member 14 from the fixed end 25 of the retention
member 21. The hook assembly member 24 and the underside of the
releasable end 26 of tire retention member 21 together cooperate to
form a hook-and-loop-type fastener. In an alternative embodiment,
no hook assembly member 24 is present, and the underside of the
releasable end 26 of the retention member 21 makes direct contact
with a portion of the upper adhesive layer 13.
[0019] For use the catheter securement device is packaged with
release layers positioned on the exposed adhesive surfaces, the
release layers being removed for use, as is well known in the art.
The catheter securement device is adhered to the patient's skin
such that the main body 11 is located at or adjacent the catheter
insertion site 98, such that the first notch 35a receives or
cradles a portion of the catheter 99 extending upwardly from the
insertion point 98. The catheter 99 is then bent sideways to extend
transversely across the main body member 11 above the pad member 14
and pressed into the upper adhesive layer 34. The catheter 99 is
aligned with the second notch 35b. The retention member 21 is then
brought down snuggly across the catheter member 99 and its
releasable end 26 is temporarily secured to the main body member 11
utilizing the hook assembly member 24. The retention member 21
maintains the catheter in contact with the pad upper surface 31,
thereby securing the catheter 99 in a controlled manner and
maintaining alignment of the catheter 99 with the second notch 35b
such that a downward slope can be readily imparted to the catheter
99 to bring it back onto the patient's skin for additional securing
using adhesive strips or the like. The presence of a retention
member notch 22a of greater dimension than the pad member first
notch 35a increases comfort to the patient by not tightly
compressing the catheter 99 at the bending region, thereby allowing
a larger loop to be present in the catheter 99 prior to its
compression by the retention member 21.
[0020] It is to be understood that equivalents and substitutions to
elements and structures set forth above, which are not intended to
be limiting unless necessary for patentability, may be obvious to
those 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.
