Cystostomy drainage device capable of measuring pressure and warning

Abstract

The invention relates to a cystostomy drainage device capable of measuring pressure and warning. The drainage device comprises a stoma tube, a disc body is connected with the tube tail of the stoma tube, the stoma tube is provided with a drainage channel, the drainage channel is provided with a horizontal opening at the tube head, a clamping air bag is arranged outside the tube wall at the front end of the stoma tube, a long seal air bag is arranged outside the tube wall on the middle section of the stoma tube, and a pressure sensor is arranged in the horizontal opening at the tube head of the stoma tube in an attached mode; the disc body is of a hollow structure, a hollow cavity of the disc body is internally provided with a pressure control and collection module and a power supply module, the upper end surface of the disk body is provided with a pressure displayer, an alarm apparatus, a clamping air bag gas injection hole and a long seal air bag gas injection hole, and a urination opening is formed in the side wall of the disc body. By means of the device, bladder pressure measuring and alarming can be conducted, when the pressure in the bladder is within a safe range, urine can be stored in the bladder, when the urine pressure in the bladder is out of the safe range, the pressure control and collection module controls the alarm apparatus to give an alarm, and then a patient can open the urination opening for urination.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a cystostomy drainage device capable of measuring pressure and alarming. Background technique [0002] Cystostomy is often used in patients with severe urinary retention caused by neurogenic bladder and lower urinary tract obstruction, who are accompanied by severe diseases who cannot tolerate surgery, and patients who undergo total urethrectomy for urethral tumors. Cystostomy can relieve acute urinary tract obstruction, eliminate the adverse effects of chronic urinary retention on the upper urinary tract, and ensure urethral healing after lower urinary tract surgery. After cystostomy, it is necessary to wear the fistula tube and drainage bag for a long time, which brings great inconvenience to the daily life of the patient. Most patients with cystostomy have impaired bladder sensory function and cannot feel the normal urge to urinate, and are prone to excess...

Problems solved by technology

After cystostomy, it is necessary to wear the fistula tube and drainage bag for a long time, which brings great inconvenience to the daily life of patients

Most patients with cystostomy have impaired bladder sensory function and cannot feel the normal urge to urinate, and prone to excessive pressure in the bladder, resulting in vesicoureteral reflux of urine and impairing normal renal function

[0003] The uncontrolled long-term drainage of urine in the prior art is likely to cause bladder contracture, and patients with severe bladder irritation and vesicoureteral reflux will damage normal renal function in the later stage; the regular clamping of the ostomy tube in the prior art When the patient has the urge to urinate, a fistula tube is opened to drain urine, which cannot keep the pressure in the bladder within a safe range, and high pressure in the bladder is prone to occur. In the later stage, urine reflux in the bladder and ureter may also occur, which will damage normal renal function.

Foley catheters commonly used in clinical practice at present, such as the cystostomy catheter without urine collection bag introduced by Chinese authorized patent: ZL201110211032.2, can play the role of drainage of urine, but cannot further evaluate the pressure in the bladder
