Problems solved by technology

[0002] At present, in order to solve the urinary incontinence of male patients or the inconvenience of urination caused by paraplegia, fractures, etc., most of them use a urine sheath catheter that is left in the catheter or glued to the outside of the penis, but it is easy to cause urinary tract infection and penile erosion. It is not easy to fix and needs to be replaced from time to time, the drainage is not smooth, and it is easy to contaminate clothes with urine

Embodiment 1

[0031] Such as Picture 1-1 with Figure 1-2 As shown, the external male urinary catheter according to Embodiment 1 of the present invention includes a sleeve body 1 for being placed outside the patient's penis, a catheter connector 3 for connecting a urine bag, a ventilation tube 4 and a one-way valve 5. The upper end of the sleeve body 1 is open, and the lower end is connected to the catheter connector 3. Both the sleeve body 1 and the catheter connector 3 are made of medical polymer materials and their inner and outer walls are covered with a coating 2. The coating Membrane 2 is dipped and molded on sheath 1 and catheter joint 3 by medical high elastic liquid polymer material, wherein the inner wall of sheath 1 is coated with a layer of annular spacer perpendicular to the axial direction of sheath 1, The annular release agent can prevent the covering film 2 from being bonded to the sleeve body 1 at the position where the release agent is coated, so that the covering film 2 ...

Embodiment 2

[0042] Such as figure 2 As shown, the external male urinary catheter of the second embodiment of the present invention is basically the same as the first embodiment, and their difference is that the external male urinary catheter of the second embodiment is additionally provided with one or more annular airbags Q, each The annular airbags Q are evenly spaced along the axial direction of the sleeve body 1; the ventilation pipe 4 is provided with a nozzle corresponding to each additional annular airbag Q, and the nozzles added by the ventilation pipe 4 are all fixed on the outer wall of the sleeve body 1 and communicated with each other. The corresponding annular airbag Q. The uppermost one of the annular airbags Q is preferably set close to the upper opening of the sleeve body 1 .

[0043] The preparation method of the external male urinary catheter of the second embodiment of the present invention is basically the same as that of the first embodiment. agent, and each layer ...

Abstract

The invention discloses an external male catheter and a preparing method thereof. The external male catheter comprises a sleeve, a catheter connector, an air tube and a one-way valve. An opening is formed in the upper end of the sleeve, and the catheter connector is connected with the lower end of the sleeve. The sleeve and the catheter connector are both integrally made of medical polymer materials, and the inner wall faces and the outer wall faces of the sleeve and the catheter connector are all covered with covering films. The covering films are formed in the mode that the sleeve and the catheter connector are dipped into liquid polymer materials. The inner wall face of the sleeve is coated with a layer of annular parting agents perpendicular to the axial direction of the sleeve, the portion, coated with the parting agents, of the corresponding covering film can be prevented from being spliced to the sleeve through the annular parting agents, and an annular air bag is formed by the portion, coated with the parting agents, of the corresponding covering film and the sleeve. A tube opening in one end of the air tube is fixed to the outer wall face of the sleeve and communicated with the annular air bag, a tube opening in the other end of the air tube is connected with the one-way valve, and therefore the annular air bag can be inflated or deflated through the air tube and the one-way valve. The external male catheter has the advantages of being high in use safety and easy to fix.

Description

technical field [0001] The invention relates to a medical device and a preparation method thereof, in particular to an external male urinary catheter and a preparation method thereof. Background technique [0002] At present, in order to solve the urinary incontinence of male patients or the inconvenience of urination caused by paraplegia, fractures, etc., most of them use a urine sheath catheter that is left in the catheter or glued to the outside of the penis, but it is easy to cause urinary tract infection and penile erosion. It is not easy to fix and needs to be replaced from time to time, the drainage is not smooth, and it is easy to contaminate clothes with urine. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an external male urinary catheter and a preparation method thereof. [0004] To solve the problems of the technologies described above, the technical scheme adopted in the present invention is as fo...
