Abstract
CATHETER SUPPORT ASSEMBLY
ABSTRACT OF THE DISCLOSURE
A support assembly for a catheter extending from a patient's body comprising, a support member of compressible foam material having a slot extending from an outer edge of the sup-port member, and adhesive on an inner surface for securing the support member to the patient's body with the catheter received in the slot. The support member has a sufficient thickness to cushion the patient's body and prevent kinking of the catheter when the patient reclines on the support member.
ABSTRACT OF THE DISCLOSURE
A support assembly for a catheter extending from a patient's body comprising, a support member of compressible foam material having a slot extending from an outer edge of the sup-port member, and adhesive on an inner surface for securing the support member to the patient's body with the catheter received in the slot. The support member has a sufficient thickness to cushion the patient's body and prevent kinking of the catheter when the patient reclines on the support member.
Description
10~2S54 BACXGROUND OF THE INVENTION
The present invention relates to catheter assemblies.
During certain medical procedures a distal end of a catheter is positioned inside the patient's body, with a proximal end portion of the catheter extending outside the patient's body.
The catheter may remain in this position for relatively short or for extended lengths of time, and the catheter may be used to drain fluids from the patient's body or inject fluids into the patient's body at a location where the patient reclines on the catheter. For example, in a continuous epidural or caudal anes-thesia procedure an anesthetic solution is periodically injected through a catheter into the epidural space or sacral canal of the patient, respectively, while the patient may recline on his back over the catheter during a surgical procedure. Thus, it is neces-sary to prevent kinking of the catheter during the procedure,else the lumen of the catheter may become closed, preventing fur-ther injection of the anesthetic solution.
~; .
SUMMARY OF THE INVENTION
A principal feature of the present invention is the provision of an assembly of simplified construction for support-; - ing a catheter during a surgical procedure.
The support assembly of the present invention comprises, a support member of compressible foam material having a slot extending from an outer edge of the support member, and pressure-sensitive adhesive on an inner surface.
A feature of the present invention is that the support member may be secured to the patient's body by the adhesive after .
10~2554 placement of the catheter with the catheter received in the slot.
Another feature of the invention is that the support member has a sufficient thickness to prevent kinking of the catheter when the patient reclines on the support member.
Thus, a feature of the invention is that the support member may be readily placed at its support position, and the support member minimizes the possibility of catheter blockage during subsequent use of the catheter.
Further features will become more fully apparent in the following description of the embodiments of this invention and from the appended claims.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
_ Although for convenience the support assembly of the present invention will be described primarily in connection with a continuous epidural anesthesia procedure, it will be understood that the assembly may be used for other suitable procedures. For example, the support assembly of the present invention may be used in connection with a continuous caudal anesthesia procedure, or for draining body fluids from a patient, as desired.
Referring now to Figs. 1-3, there is shown a support assembly generally designated 20 having a support member 22 which is made from a relatively soft, flexible, and compressible foam material, such as urethane foam. The support member 22 may have lS a generally cylindrical shape, as shown, and has a tapered slot or slot means 24 of generally triangular configuration extending .
through the thickness of the support member between outer and inner surfaces 34 and 36, respectively, of the support member, and extending from an inner central portion of the support member ;~20 to an outer edge 26 of the support member 22. The slot 24 has an outer portion 28 of larger diameter than the outside diameter of a catheter to be received in the slot, and an inner portion 30 which may be smaller than the outside diameter of the catheter.
As shown, the apex 32 of the slot 24 may be located at the center of the support member 22.
~he support member 22 has a coating of pressure-sensi-tive adhesive 38 on its inner surface 36, and a release sheet 40 releasably attached to and covering the adhesive 38 on the sup-port member 22. With reference to Fig. 3, the release sheet 40 may be removed from the adhesive 38 in order to expose the adhe-sive and secure the support member 22 on the body of the patient, as will be described below.
The use of the support assembly of the present inven-tion for a spinal epidural anesthesia procedure is described in connection with Figs. 4-6. As shown in Fig. 4, a needle N is positioned in the patient's body according to known procedures with an opening O of the needle N being located in the epidural space E of the patient. A catheter C is advanced through the needle N and through the needle opening O until a distal end D
of the catheter C is located in the epidural space E with a prox-imal end portion P of the catheter C being located outside the patient's body. The needle N is then removed from the patient's body and from the proximal end portion P of the catheter C, while the distal end D of the catheter C remains in place in the patient's body. Next, the proximal end portion P of the catheter C is connected to a syringe (not shown) which contains an anes-- 20 thetic solution, and the syringe is utilized to periodically inject the anesthetic solution through the catheter C into the epidural space E throughout the duration of a surgical procedure.
However, if the patient reclines on his back over the catheter during the surgical procedure, it has been found that the patient's weight may cause kinking and blockage of the catheter. Thus, if further anesthesia is required during the surgical procedure and if the catheter is blocked, the surgical procedure must be inter-rupted in order to reposition the patient and open the catheter ~.()B2554 for injection of further anesthetic solution.
According to the present invention, as illustrated in Figs. 5 and 6, after placement of the catheter and after removal of the needle N from the catheter, the release sheet is removed from the adhesive 38 of the support member 22, and the support member is attached to the patient's body by the adhesive 38 with the proximal end portion P of the catheter C being received in the slot 24 of the support member. The support member 22 then serves as a cushion about the site where the catheter enters the patient's body. The support member has a sufficient thickness - -between its outer and inner surfaces 34 and 36, respectively, to prevent kinking of the catheter when the patient reclines on the support member during the surgical procedure. Thus, the support member 22 assures that the catheter is maintained with its lumen open during the surgical procedure, in order that the anesthetic solution may be injected into the epidural space without diffi- -culty at selected intervals during the surgical procedure. ~
The foregoing detailed description is given for clear- ~-ness of understanding only, and no unnecessary limitations should be understood therefrom, as modifications will be obvious to those skilled in the art.
