Bladder fistulation tube

Abstract

The invention discloses a bladder fistulation tube. The bladder fistulation tube comprises a duct, a water sac, an extension hose and a leakproof assembly, wherein an urine guiding channel and a watersac channel are formed in the duct; an urine guiding outlet corresponding to the urine guiding channel and a water filling opening corresponding to the water sac channel are formed in the rear part of the duct; an elastic pressure valve is arranged in the urine guiding channel; one end of the extension hose communicates with an inlet of the urine guiding channel, and a plurality of first urine inlets are formed in the side wall of the other end of the extension hose; a through hole is formed in the center of the leakproof assembly, and the leakproof assembly can be movably arranged on the duct in a penetrating manner; and a gel layer is arranged on one side of the leakproof assembly, so that the leakproof assembly can be attached on the skin. The bladder fistulation tube disclosed by theinvention can enable urine in the urinary bladder to be completely drained, the problem of urine leakage infection can also be effectively prevented; unidirectional flow of the urine can be realized,and the pressure of the fistulation tube can be controllable; and the duct can also be bent, so that the bladder fistulation tube is convenient for a patient to use and fix.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a cystostomy tube. Background technique [0002] In the actual clinical work of urology, permanent bladder fistula caused by various reasons is very common. Currently, for cystostomy, a dedicated cystostomy tube is generally used. The cystostomy tube in the prior art generally includes a ostomy tube, on which a water bag is arranged, the tube head of the ostomy tube is provided with a urine inlet, and the tail end of the ostomy tube is provided with a urine outlet and a water filling port. A baffle or fixing sheet is also arranged on the ostomy tube to fix the ostomy tube. When in use, insert the tube head of the ostomy tube into the appropriate position of the bladder, fill the water bag with water, gently pull the ostomy tube to make the water bag fit the inner wall of the bladder, and then stick the block or fixed piece to the body surface to fix it. Usually wrapped with me...

AI Technical Summary

Problems solved by technology

[0003] But also there are following problems in existing cystostomy tube: 1, leakage of urine: can not be closed completely between ostomy tube and abdominal wall fistula opening, and urine flows out from the slit between ostomy tube and ostomy opening, makes patient be full of urine. Bad smell, affecting the quality of life and the environment

2. The drainage is incomplete. The cystostomy tube on the abdominal wall cannot completely drain the urine out of the bladder due to gravity. Only part of the urine in the bladder is drained out each time. The residual urine in the bladder will cause infection and bladder stones for a long time

3. The ostomy tube cannot be bent, and the stoma opening is in the middle of the lower abdomen. The current ostomy tube is a urinary catheter, which cannot be bent, which affects dressing and quality of life

4. The pressure is uncontrollable: the pressure of the current cystostomy tube is uncontrollable. If the fistula tube is blocked or under pressure, the pressure in the bladder exceeds the safe pressure, which may cause hydronephrosis and functional damage of the upper urinary tract
