Novel bladder fistulization tube for urinary surgery

Abstract

The invention discloses a novel bladder fistulization tube for urinary surgery, and relates to the technical field of medical instruments. The novel bladder fistulization tube is characterized in that the novel bladder fistulization tube comprises a first expansion bag and a second expansion bag, the top of the second expansion bag is in contact with the bottom of the first expansion bag, a through hole penetrating through the top and the bottom of the second expansion bag is formed in the center of the second expansion bag, and an annular flow guiding device is arranged at the bottom of the second expansion bag. According to the fistulization tube, the expansion bag can press the bladder without being filled with normal saline, so that urine leakage is prevented; the design of the double expansion bags is adopted, the inner bladder section of the bladder fistulization tube can be effectively fixed, and stimulation to the triangular area of the bladder is prevented or reduced; meanwhile, in the replacement process of the bladder fistula, one expansion bag and the bladder are always in a pressed state, and the phenomenon of urine leakage in the replacement process is avoided; and finally, the double balloons designed by the invention have the aim of storing urine, so that a patient does not need to hang a urine collection bag all the time within a certain time, and the effect of being convenient to carry is achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to a novel urological 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. [0003] 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 proper position of the bladder, fill the water bag with water, and gently pull the ostomy tube so that the water bag fits the inner wall of the bladder, and then fix it with wrapped medical tape...

AI Technical Summary

Problems solved by technology

[0005] 1. Existing cystostomy catheters usually use a dilatable bladder to prevent urine leakage. By filling the dilated bladder with physiological saline, the dilated bladder can be pressed against the bladder, thereby achieving the leak-proof effect. A water injection tube is connected to the fistula, which has a complex structure and requires a larger stoma

[0006] 2. At present, the fistula tube after cystostomy is not fixed, or the fixation is not firm, which may easily cause the bladder tube to not be close to the anterior wall of the bladder, which will cause the bladder trigone to be stimulated by the bladder tube, resulting in urinary tract irritation symptoms, and Bladder spasm pain, etc., affecting the patient's quality of life

[0007] 3. The cystostomy tube generally needs to be replaced once a month. When replacing it, the cystostomy tube needs to be taken out, but after taking it out, some urine will flow out from the stoma, which is easy to cause infection to the surrounding tissues

[0008] 4. The current cystostomy tube needs to be connected with the urine bag, and the fistula tube itself does not have the function of storing urine, so the patient needs to carry the urine bag all the time, which affects daily life
