One-way pressure valve urethral catheterization device

Abstract

The invention specifically discloses a one-way pressure valve urethral catheterization device. The one-way pressure valve urethral catheterization device comprises a tube body, wherein a urethral catheterization detection device is arranged in the tube body; one end of the outer side of the tube body is detachably connected with a urinary catheter; the urethral catheterization detection device comprises a urethral catheterization auxiliary disc; a urine pressure detection hole is formed in the urethral catheterization auxiliary disc; a pressure sensor is fixedly connected to the urethral catheterization auxiliary disc on one side of the urine pressure detection hole, wherein an annular electromagnet is arranged on the periphery of the urine pressure detection hole and in the urethral catheterization auxiliary disc; a switch disc is arranged on the other side of the urethral catheterization auxiliary disc; an auxiliary block is fixedly connected to the switch disc, wherein a second urethral catheterization hole is formed in the switch disc; a magnet is arranged on one side of the switch disc and is in magnetic connection with the annular electromagnet; and the urinary catheterization auxiliary disc and the switch disc are matched with each other, so that the urinary retention condition caused by the fact that a urinary catheter cannot be opened in time due to reduction of bladder sensitivity of a patient can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of medical catheterization, in particular to a one-way pressure valve catheterization device. Background technique [0002] With the advent of an aging society, the number of patients with neurogenic bladder caused by diabetes and other basic diseases is gradually increasing. Indwelling urinary catheter or indwelling cystostomy tube is a common way to solve the problem that patients cannot urinate on their own. However, most of these patients have dull bladder sensation, and cannot timely and accurately perceive and judge whether it is necessary to open the urinary catheter and drain urine. If the urinary catheter is opened for a long time to drain urine, the bladder will shrink, but if the catheter is clamped and the catheter is not opened in time, it will cause urinary retention, hydronephrosis, and damage kidney function. , so how to open and close the urinary catheter in time is an urgent problem for mo...

Problems solved by technology

However, most of these patients have dull bladder sensation, and cannot timely and accurately perceive and judge whether it is necessary to open the urinary catheter and drain urine

If the urinary catheter is opened for a long time to drain urine, the bladder will shrink, but if the catheter is clamped and the catheter is not opened in time, it will cause urinary retention, hydronephrosis, and damage kidney function.
