Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a medical external delivery tube or catheter (
The present invention relates to a locking device for holding a catheter (hereinafter simply referred to as a catheter) inside a patient's body.

The present invention is particularly useful for retaining hypogastric catheters within the body.

It is often necessary to insert a catheter into a patient's body and maintain the catheter in the inserted position for a relatively short period of time.

In connection with the aforementioned need, it is an object of the present invention to provide an improved retention or engagement device which is simple in construction, inexpensive and disposable.

Accordingly, the present invention comprises a disc suitable for positioning and securing on the body of a patient, a clamp extending from one side of the disc, and a lock, the disc having an opening through which a catheter can pass, said clamp a first clamp portion secured to the disc adjacent the opening; and attached to the first clamp portion by a hinge and adapted to be folded over the first clamp portion. a second clamp portion, each clamp portion having a longitudinal groove that cooperates to allow passage of an open-ended catheter when the clamp portions are folded over. It is designed to define the passage,
The present invention provides a locking device for holding a catheter in a patient's body, wherein the lock is adapted to fix the two clamp parts together when the two clamp parts are folded together. be. The locking device of the present invention does not exert much force beyond the clamping force required to hold the catheter, thereby reducing the risk of deformation and occlusion of the catheter lumen.

Hereinafter, the present invention will be explained in more detail using the accompanying drawings.

The locking device for retaining a catheter in the body of a patient, shown in the accompanying drawings, is integrally molded from a suitable plastic material, such as polyethylene or polypropylene, and has a disc 1 or face plate which can be placed in the body of the patient. . The disc 1 has a plurality of holes 2 through which it can be fixed to the patient's body by means of sutures.

Alternatively, the disc can be secured to the patient's body by suitable surgical adhesive or surgical adhesive tape passed over the disc or other suitable means.

The disc 1 has a central opening 3 through which a catheter C can pass. A clamp extends from one side of the disk in contact with the opening 3. This clamp has two parts 4, 5, which are joined by a hinge part 6.

An opening 7 passing through the hinge 6 provides provision for the clamp.

Catheter C is inserted through opening 7 as described below.

The clamping part 5 remote from the disc 1 can be folded over the clamping part 4 or closed. Each clamping part has a semi-cylindrical groove 8,9. When the two clamp parts are folded over, these grooves cooperate to provide a cylindrical passageway which accommodates the catheter C which enters the opening 7 and extends through the opening 3. The groove 9 of the clamping part 5 has a small section at the V end remote from the disc 1. When the two clamping parts are folded together, this end of the clamping part 5 adjoins the disc 1; The passage defined by the two grooves clamps the contained catheter at this end to prevent the locking device from slipping over the catheter.

The lock for fixing the two clamp parts together is provided by teeth 10 of a pair of jaws 11 provided at the end of the clamp part 5 remote from the disk 1 in the open position. When the clamp part 5 is folded over the clamp part 4, these teeth engage the clamp part 4, as shown in FIG. 1, to hold the two clamp parts in the folded or closed position.

When the clamp part is in this position, the catheter O is firmly secured by the locking device.

In use, a hypogastric or other catheter C is inserted through the openings 7 and 3 and then into the patient's body. Once the catheter has reached the desired position, the locking device is slid over the catheter until the disc 1 contacts the patient's body. Then, secure disc 1 to the body. Clamp part 5 is then folded over clamp part 4 and secured in the closed position by means of teeth 10. In this way, the catheter is placed at the desired location within the body. 14. When removing the catheter from the body. The catheter can be moved with the locking device.

In the variant embodiment shown in FIG.
is the preparation. Ear 12 has an opening 13 through which a suture can be passed to fasten ear 12 and disc 1 to the patient's body. The ears 12 and discs 1 can also be attached to the body with adhesive tape.

In FIG. 3 I indicates a reinforcing spring 1.1 which can be attached to the clamp and is conveniently made of plastic material. Because the catheter C passes through this spring, the possibility of catheter bending upon exiting the clamp is reduced. Alternatively, the spring 14 can be placed loose so that the clamp can be slid out after it has been closed.
