Pressure measurement urethral catheter

Abstract

The invention provides a pressure measurement urethral catheter. The urethral catheter is mainly used for clear intermittent catheterization patients or long-term indwelling catheterization patients.The urethral catheter comprises a main catheter body and a pressure measurement module, the main catheter body is in a tube shape with two open ends and a hollow interior, the hollow interior is a urinary catheterization cavity, a urine inlet is formed in the top of the main catheter body, and a urine outlet is formed in the tail end of the main catheter body; a hollow interior of the pressure measurement module is a pressure measurement cavity, one end of the pressure measurement module is connected with the main catheter body, and a one-way valve is arranged at a pressure measurement openingin the other end; a segment of pressure transmission catheter with a small cavity inner diameter is arranged between the main catheter body and the pressure measurement module, and the urinary catheterization cavity is communicated with the pressure measurement cavity through a pressure transmission cavity of the pressure transmission catheter. By means of the pressure measurement urethral catheter, the bladder pressure during urination can be detected, the safe bladder pressure is determined, and a personalized urinary continence and urination mechanism is formed.

Description

technical field [0001] The invention relates to a pressure-measuring catheter, in particular to a catheter capable of measuring bladder pressure, and belongs to the technical field of medical devices. Background technique [0002] Catheterization is divided into two types: intermittent catheterization and indwelling catheterization. Intermittent catheterization is a method of catheterization in which a catheter is inserted into the bladder from the urethral opening, and the catheter is removed immediately after the urine in the bladder is emptied. Interstitial catheterization can relieve excessive bladder filling, reduce the pressure in the bladder, restore the blood circulation of the bladder wall, reduce the incidence of urinary tract infection, and reduce the incidence of vesicoureteral reflux, hydronephrosis and urinary stones. To improve the psychological barrier of patients, intermittent catheterization is the gold standard for assisting bladder emptying. Because pati...

[0003] Chinese Patent Announcement No. CN 203989396 discloses a disposable connecting tube for urination, including a urine tube connected to a three-way joint. The two branches of the three-way joint are respectively connected with a connecting tube and a pressure measuring tube. The end of the pressure measuring tube is provided with a machine-end connector connected to the air pressure sensor on the bladder training instrument. The connector is equipped with a hydrophobic membrane. The hydrophobic membrane can only ventilate but not liquid, but when the urine approaches the hydrophobic membrane, the hydrophobic membrane Block the urine from continuing to flow, and the hydrophobic membrane itself has limited deformation, and the air inside the pressure measuring tube cannot be pushed to the pressure sensor by the urine, so this method of measuring bladder pressure has the disadvantage of inaccurate measurement data

[0004] Chinese patent announcement number CN 104856665 discloses a bladder pressure detection device, including an expansion end, a pressure detection end, and a pressure gauge. When in use, liquid or gas needs to be injected into the expansion end, and the pressure is received through the expansion end located inside the bladder, and then transmitted to the The pressure gauge at the pressure detection end, this technical solution uses the expansion end to receive and transmit pressure, and liquid or gas needs to be injected during use, which is cumbersome to use and reduces the work efficiency of medical staff

However, the buffer airbag in this technical solution has a complicated structure and high processing cost, which is not conducive to long-term use by patients.
