Preferably, the catheter head includes a sealing gasket that fits with the inner cavity wall of the front end of the catheterization sleeve body and a plug connector that is provided on the sealing gasket and can be inserted into the socket. Urine is directed to the catheterization port of the external urine bag.

Preferably, the front end surface of the gasket is formed with several convex rings arranged at intervals.

Preferably, the rear end surface of the sealing gasket is a spherical surface formed according to the outline of the glans head.

Preferably, the gasket and the plug connector are integrally formed.

Preferably, the urinary catheter is a circular through hole.

Preferably, the urinary catheter is in the shape of a cone with a small diameter at the rear end and a large diameter at the front end.

Preferably, the catheter body can be rolled up along its length.

Preferably, a protruding edge extends from the front end of the urethral sleeve body from the socket, and the plug connector protrudes from the protruding edge.

Preferably, the flange and the plug connector are sealed by wrapping tape.

It can be seen from the above technical solutions that the elastic catheter body of the present invention can be directly sleeved on the male penis, and its structure is similar to that of a condom, which can avoid the occurrence of complications caused by intubation; The sealed connection of the catheter head can guide urine into the external urine bag, which is not only convenient to use, but also simple to operate.

Detailed ways

The present invention will be described in detail below with reference to FIG. 1 . The exemplary embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

As shown in Figure 1, the present invention provides a male urinary catheter, which comprises an elastic catheter cover body 1 that can be sleeved on the male penis, the front end of the urinary catheter cover body is closed, and the rear end has an opening 11 for the insertion of the penis; The material of the catheter body can be made of silicone, rubber or other materials with elastic functions, and the structure is similar to that of a condom, so it can be worn for a certain period of time, and the safety is guaranteed. The edge of the opening 11 at the rear end of the catheter cover body of the present invention is formed with an elastic fixing ring 2. When the catheter cover body is sleeved on the penis, the fixing ring has greater elasticity, which can fix the penis and prevent the catheter cover. The body slides or slides off the penis; the front end of the catheter cover body is provided with a socket 12 communicating with the inner cavity of the catheter cover, and a catheter head 3 that can guide urine to an external urine bag is sealed and inserted in the socket. Therefore, in the present invention, the catheter head is used to introduce urine into the external urine bag, and there is no need to insert a urinary catheter, and complications can be avoided. When in use, the catheter head is put into the inner cavity from the opening of the catheter cover body, then inserted into the socket, and then the catheter cover body is put on the penis, which is not only convenient to use and simple to operate, but also the catheter head and catheter The sleeve body can be produced separately, and the processing is simple and the cost is low.

The catheter head 3 of the present invention includes a sealing gasket 31 that is fitted to the inner cavity wall of the front end of the catheterization sleeve body, and a plug connector 32 disposed on the sealing gasket and inserted into the socket. The plug connector and the sealing gasket are formed with a The urine is directed to the catheter port 33 of the external urine bag. In the implementation process, the sealing gasket can prevent urine leakage, and the plug connector can export the urine, thereby realizing the exporting of the urine and avoiding the need to insert a urinary catheter. Preferably, the front end surface of the gasket is formed with several convex rings 34 arranged at intervals. On the one hand, it can increase the friction between the gasket and the catheter body to prevent the gasket from sliding; on the other hand, the convex ring is provided with a Multiple turns can further improve sealing. Preferably, the rear end surface of the sealing gasket is a spherical surface shaped according to the outline of the glans head, so as to avoid bumping the glans head and ensure comfortable wearing; the sealing gasket and the plug joint are integrally formed to ensure that the sealing gasket and the plug joint are tightly connected.

The urinary catheter of the present invention is a circular through hole, which can prevent urine leakage; preferably, the urinary catheter has a tapered shape with a small diameter at the rear end and a large diameter at the front end, which can prevent the backflow of urine. The catheter cover body of the present invention can be rolled up along its length direction, when not in use, the catheter cover body can be rolled up on the fixing ring, and its volume is small, which is convenient for storage and transportation; when in use, it is only necessary to stretch the catheter The urinal body can be put on the penis after inserting the catheter head, and the use and operation are more convenient.

Preferably, a protruding edge 13 extends from the front end of the catheter body from the socket 12, and the plug connector extends out of the protruding edge, which can be more convenient for the plug connector to be inserted. The raised edge and the plug connector are sealed by wrapping the tape 4, which further prevents the urine from being exposed and improves the sealing performance of the device. The present invention adopts the separate arrangement of the catheter cover body and the catheter head to realize the export of urine during the operation.
