self-control catheter

Abstract

The invention discloses an auto-controlled catheter. A switch device on the auto-controlled catheter is formed by connecting a switch valve and a switch assembly into a whole through a valve rod sleeved with a spring shaft, wherein the switch valve is formed by matching of a steel ball and a valve seat; the steel ball is connected with one end of the valve rod into a whole; the valve seat is connected with a silica gel sleeve; the switch valve is arranged in one end of a pipe body; the switch assembly is formed by mounting a button and a cross shaft connected with a spring in an evacuating catheter and connecting a spring seat, a fixed seat and the evacuating catheter; the switch assembly is arranged in the other end of the pipe body; the button and one end of the cross shaft are in tight fit connection; and the other end of the valve rod is fixed on the other end of the cross shaft. The auto-controlled catheter is inserted into the urethra for use without carrying of a urine bag; a urine opening directly faces a urinal or a toilet only by lifting the button; and the button returns to the normal position by loosening the hand after the urine is discharged. The auto-controlled catheter can be used by people of all ages and both sexes; the secret sorrow of patients with diseases of urinary systems is solved; the auto-controlled catheter is simple and convenient to operate, is made of silica gel and a stainless steel material, and is durable in use; the mental stress and economical burden of the patients are greatly reduced; and the living quality of the patients with diseases of urinary systems is greatly improved.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a self-control urinary catheter which can be used without wearing a urine bag. Background technique [0002] The urinary catheter used in the existing hospital also needs to be used in conjunction with the urine bag. In clinical work, indwelling the urinary catheter is also for finding out the cause of disease except catheterization.
