Description

The invention relates to a locking device for retaining a tube or

  medical or surgical catheter (hereinafter referred to as uniformly catheters) in position

in the body of a patient.

  The invention is particularly, but not exclusively, useful for holding in position in the body

a suprapubian catheter.

  It is often necessary to introduce a catheter into the body of a patient and to retain it in an inserted position for a relatively long period of time. An object of the invention is to provide an improved locking or retaining device for this purpose. , which is of construction

  simple and inexpensive and that is a disposable item.

  Accordingly, the invention provides a locking device for retaining a catheter positiion in the body of a patient and characterized in that it comprises a disc designed to be placed on the body of a patient and there to be fixed and having an opening through which a catheter may pass, a forceps extending from a face of the disc and comprising a first clamp portion attached to the disc near the opening thereof and a second clamp portion attached to the first part by a hinge so that the second gripper part can be folded over the first one, each gripper part having a longitudinal groove, these grooves cooperating when the gripper parts are folded over one another to define an open passage at each end and through which a catheter may pass, and a lock for fixing the two clamp parts together when they are folded over one another. The blocking of the invention does not exert a larger blocking force than is necessary to maintain a catheter in place. This reduces to a certain extent the possibility of distortion.

  and occlusion of the catheter lumen.

  An embodiment of the invention is represented by the accompanying diagrammatic drawings in which FIG. 1 is an elevation of a locking device according to the invention in its closed position, FIG. 2 is a perspective of the same locking device in a open position, and Fig. 3 shows a suprapublian catheter

  of a modified disk according to the invention.

  The device for retaining booklets in position in the body of a patient, as represented by the drawing, is molded in one piece

  made of a suitable plastic material, for example polyethylene

  Lenin or polypropylene and includes a disc 1 or face plate that can be placed on the body of a patient The disc 1 has several holes 2 so that it can be attached to the body by sutures passing through These holes can also be attached to the patient's body by a suitable surgical adhesive material or surgical adhesive tape.

  over the disc, or in any other appropriate manner.

  The disk 1 has a central opening 3 through which a catheter C can pass. A clip is on one side of the disc 1, near the opening 3. The clip comprises two parts 4, 5 interconnected by a hinge part. 6 An opening 7

  is provided in the clip <and passes through the hinge 6.

  Catheter C can be inserted through this opening

7 as will be described below.

  The clip part 5 located at a distance from the disk

  1 can be folded or closed on the clamp part 4.

  Each of the clamp portions has a semi-groove

  cylindrical 8, 9 When the two gripper portions are folded one upon the other, these grooves cooperate to form a cylindrical passageway accommodating a catheter

  C centered by the opening 7 and exceeding the opening 3.

  The groove 9 of the clamp portion 5 has a portion

  of reduced section at the opposite end to the disk 1.

  When the two gripper parts are folded one on the other, this end of the gripper portion 5 is adjacent to the disc 1 and a catheter housed in the passage defined by the two grooves will be pinched at this point so that the device will not be able to slide on the catheter A lock for fixing the clamp portions between them is formed by the teeth 10 of a pair of jaws 11 at one end of the clamp portion 5 located at a distance from the disc 1 When the part of clamp 5 is bent on the clamp part 4, these teeth apply to the clamp part 4 as shown in Fig 1 to hold the two clamp parts in their folded or closed position When they are in this position, catheter C is firmly blocked by

the device.

  In use a suprapubic or other catheter, C, is inserted through the openings 7 and 3 and inserted into the patient's body. When the catheter is in the desired position, the blocking device is slid over the catheter. what the disc touches

  the body of the patient One then fixes the disc 1 to the body.

  The clamp portion 5 is then folded over the clamp part 4 and they are secured in their closed position by the teeth 10. The catheter is then firmly inserted into the body, the catheter can be thrown away as well.

although the blocking device.

  In the variant shown in FIG. 3, the disc 1 is provided with lugs 12 to facilitate the attachment of the disc to the body of a patient. The lugs 12 have openings 13 through which sutures can be passed to fix the ears. and the disc to the patient's body or again, they can

  to be attached to the body with tape -

  FIG. 3 shows a reinforcing spring 14 which can be fixed to the clip and which is advantageously made of plastic. Catheter C passes through this spring, which reduces the risk of folding the catheter when it leaves the clip. , the spring 14 can be free and arranged so as to slip on

  the clip once the clip is closed.

Claims (5)

R E V E N D I C A T IO N S   A blocking device for retaining a catheter in position in the body of a patient and characterized by comprising a disc adapted to be placed on and attached to a patient's body and having an opening thereon. through which a catheter, a forceps extending from one side of the disc and comprising a first clamp portion attached to the disc near the opening thereof and a second clamp portion attached to the first part by a hinge, can be passed through so that the second gripper portion can be folded over the first, each gripper portion having a longitudinal groove, these grooves cooperating when the gripper portions are folded over one another to define an open passage at each end and through which can pass a catheter, and a lock used to secure the two clamp parts together when they are folded one on the other.   2 Device according to claim 1, characterized in that the locking is formed by teeth provided on a pair of jaws disposed at the end   the second part of the clamp that is away from the disc.   3 Device according to one of the claims   1 and 2, characterized in that a reinforcing spring is disposed at the end of the device which is remote from the disc when said device is in the closed position, so as to surround the part of the catheter which exceeds this end.   4 Suprapubic catheter, characterized in that it is provided with a locking device according to one of claims 1 to 3.
