technical field

The invention relates to medical aids, in particular to a ureter sealing cap.

Background technique

Patients with urostomy refer to patients with abdominal urostomy after total cystectomy for bladder tumors. It is divided into ileal cystostomy and ureterocutaneous stoma. Generally, each urostomy bag is used for 7-10 days. However, due to the continuous leakage of urine during the replacement of the urostomy, it is more difficult to change the bag. The urine leakage is also because the skin around the urostomy is wet and difficult to adhere to the ostomy bag. irritant dermatitis or skin damage; when changing the bag at home, the patient uses non-sterile items to place at the urostomy, which increases the chance of infection and the number of bag changes; increases the psychological burden and economic burden of the patient.

Therefore, how to provide an auxiliary product that prevents urine from flowing out when replacing the urostomy bag is a technical problem to be solved urgently by those skilled in the art.

Detailed ways

In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

The embodiments of the present invention are written in a progressive manner.

As shown in Figures 1 and 2, the ureteral sealing cap provided by the present invention includes a sleeve body 2 and a seal ring 1 with an adhesive layer 11 on one side. One end of the sleeve body 2 is open and the other end is closed. The socket is fixedly connected with the sealing ring 1 and the casing 2 is located on the non-adhesive side of the sealing ring 1; the casing 2 includes a casing body 21 and a water-absorbing layer 22 arranged on the inner wall of the casing body 21, and the water-absorbing layer 22 surrounds the casing The inner wall of the body body 21 is arranged to form a ureteral channel 3 matching with the ureteral body.

The ureter sealing cap provided by the present invention includes a sleeve body 2 with one end open and the other end closed, and a sealing ring 1 with an adhesive layer 11 on one side. Since the sleeve opening of the sleeve body 2 is fixedly connected with the sealing ring 1 and The body 2 is located on the side of the non-adhesive surface of the sealing ring 1. Therefore, when in use, the sleeve body 2 can be pasted and fixed on the surface of the human body through the sealing ring 1. Since the sleeve 2 includes a sleeve body 21 and a water-absorbing layer 22 arranged on the inner wall of the sleeve body 21, and the water-absorbing layer 22 is arranged around the inner wall of the sleeve body 21, a ureteral channel 3 matching the ureteral tube is formed; therefore, When in use, the ureter can be inserted into the sheath 2 through the ureter channel 3, and due to the existence of the water-absorbing layer 22, the urine flowing out of the ureter can be absorbed by the water-absorbing layer 22 in time, thereby avoiding leakage of urine. The ureter sealing cap provided by the invention can be well adapted to the ureter, can reliably temporarily seal the ureter, and is easy to operate. The sealing cap is scientific in design, simple in structure, easy to use, and low in cost. It is a disposable medical appliance, clean, hygienic, safe and reliable, and can fundamentally solve the problem of urine flowing out of the ureter when changing the urostomy belt, effectively solving the problem. It solves the problem of easy adverse reactions caused by changing the ostomy bag in a non-sterile environment after urostomy patients, and is suitable for clinical practice.

Preferably, anti-slip protrusions can be provided on the inner wall of the water-absorbing layer 22 . By arranging anti-slip protrusions on the inner wall of the water-absorbing layer 22 , it can ensure that the sheath 2 and the ureter are well and reliably matched together, and further prevent the ureter from falling off from the sheath 2 .

As one of the embodiments of the present invention, the anti-slip protrusion may be an anti-slip thread.

Preferably, the material of the water-absorbing layer 22 can be selected from superabsorbent resin materials. Due to the selection of super absorbent resin material with strong water absorption capacity, it can timely absorb the leakage of urine from the ureter when changing the stoma bag, keep the skin around the stoma dry all the time, and reduce the irritation of urine to the skin.

Certainly, the material of the water-absorbing layer 22 may also be other water-absorbing materials such as medical absorbent sponge or medical cotton cloth.

Preferably, the adhesive layer 11 can be a medical adhesive, and the adhesive surface of the adhesive layer 11 can be provided with a release film. The setting of the isolation film is conducive to maintaining the viscosity of the adhesive layer 11, and the isolation film can be torn off from the adhesive layer 11 during use; the use of medical adhesive can prevent patients from being allergic to other viscous substances, and then cause adverse reactions.

Preferably, the sheath body 21 can be made of hard medical plastic material or medical rubber material. The hard medical plastic material or medical rubber material can not only play a waterproof role, blocking the entry of external water body and causing infection, but also better protect and fix the ureter, preventing the ureter from being bumped when changing the ostomy bag. Or the extrusion causes deformation of the ureter.

Preferably, the inner diameter of the sealing ring 1 is equal to the diameter of the ureteral channel 3 , and the outer diameter of the sealing ring 1 is larger than the outer diameter of the sleeve body 21 . In this way, the sealing ring 1 isolates the water-absorbing layer 22 from the external environment, which can further reduce the possibility of external germs entering and causing infection, and at the same time further prevent the water-absorbing layer 22 from being saturated to cause urine leakage. And enlarging the area of the sealing ring 1 helps to improve the stability of pasting.

Preferably, the sealing ring 1 can be made of soft medical plastic material or medical rubber material. Compared with hard materials, soft materials can better fit the patient's skin, further improve the bonding performance of the sealing ring 1, and ensure the stability of the connection between the ureteral sealing sleeve and the human body.

The above description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
