BACKGROUND OF THE INVENTION1. Field of the Invention
The invention relates to securement devices; and, more particularly, to anchoring systems for anchoring or securing medical articles to the body of a patient.
2. Description of the Related Art
It is well known in the treatment of patients to introduce fluids and medications directly into the bloodstream. Many devices are known for quickly and easily securing a catheter, tube, etc. to the skin of a patient without suturing.
Various devices have been suggested in the past which require carefully machining of parts of said medical articles to form apertured ears or tabs to anchor the securement strands to a catheter or the like. Certain securement devices require specially manufactured strands or posts with protuberances. Other securement devices are specifically adapted to a particular type of catheter or the like thus not easily accommodating catheters of different configurations.
These devices do not put tension on the strands holding the catheter in place.
There is a need for a securement device for percutaneous sheath introducers and other medical devices which uses flexible strands for securement means thus allowing versatility and flexibility and does not require careful and expensive machining of the medical articles to be secured. Such a device should easily accommodate catheters of varying configurations.
SUMMARY OF THE INVENTIONIt is an object of this invention to provide a securement device for indwelling catheters or introducers and other medical articles which uses strands of material as the securement means of tying a catheter or the like in position on the body of a patient.
It is another object of this invention to provide such a device having a base secured to a pad adapted to be secured to the body of a patient, the base holding a catheter or the like in a firm fixed position on the base.
It is still another object of this invention to carry out the foregoing objects placing tension on the strands holding a catheter or the like in place on the base.
These and other objects are preferably accomplished by providing a pad having an adhesive backing for securement to the skin of a patient. A base is mounted on the pad having a one or more holes therethrough with an elongated strand(s) extending down through said hole or holes. The strand may be wrapped around a connector mounted on the base and tied to itself or two or more such strands, the free ends thereof tied to secure the connector to the base.
Referring now to
Securement device 10 thus includes a base 14 adapted to be secured to an anchor pad 25 (
Base 14 is secured to anchor pad 25 which is configured as shown (generally referred to as a butterfly configuration) and secured thereto in any suitable manner, such as by a solvent bond adhesive.
One or more holes 26 through 29 (
In the example shown, two such strands 16, 24 are shown adapted to be fed through holes 18 through 21 (
Each strand 16, 24 may have a pointed distal end 22 (
The anchor pad 25 may be of flexible material as is well known in the art and may comprise a layer of a closed cell, low-density polyethylene foam and a bottom layer of a medical grade adhesive. A removable paper or plastic backing 30 (see
Base 14 is comprised of two parts (
Support base 32 may be of a suitable molded polymeric material having an upper surface covering with a plurality of upstanding generally conically shaped protrusions 34 (
A spring beam 35 is mounted internally or integrated into support plate 33 for reasons to be discussed.
Holes 18 through 21 in support base 32 are aligned with like holes (

As discussed, any suitable materials may be used, such as a fabric material for pad 25 with a base 14 of polycarbonate or similar material glued to pad 25. The radiused edges 38 of the holes eliminate sharp cutting edges. Strands or sutures 16, 24 may be No. 1 braided silk sutures. Support base 32 may be of any suitable polymeric material, such as a material of about 35A Durometer.

Looking at
As seen in
Connector 12 may have one or more spaced annular grooves, such as grooves 106, 107 (
Although a particular type of connector is disclosed, having annular grooves, obviously any suitable type of connector may be used as long as strands 16, 24 can be wrapped around or through the holes and tied. The hardened ends 22 allow easy insertion through the aligned holes and the apertured ear.
The concave center 100 of upper support base 32 acts as an anti-roll channel for connector 12. This also prevents folding of the base 32 in the center.
Although 2 strands 16, 24 may be used to tie connector 12 to base 32, obviously one may be used. Thus, at least one strand is sufficient utilizing the teachings of the invention.
In a further embodiment of the invention, wherein like numerals refer to like parts of
Circular holes with radiused sides have been disclosed, as seen in
In still another embodiment of the invention, as seen in
The strands may be of silk or any flexible material that is substantially non-extendible about its long axis. The flexible beam 35 conforms to the shape of a connector mounted on the base and creates and maintains tension in the strands so as to keep any knots tight and pulls or presses the connector into the conforming surface preventing rolling. Also, beam 35 may be integral with plate 33 and base 32 with the hardness of the securement base 14 varying from the top to bottom thereof or of uniform hardness to allow both the cushioning/conforming effect of said base and the springlike character of said plate.
Although a particular embodiment of the invention is disclosed, variations thereof may occur to an artisan and the scope of the invention should only be limited by the scope of the appended claims.
