Description

Supporting component and urethral catheterization device

Technical Field

The invention relates to the field of medical equipment, in particular to a supporting assembly and a urethral catheterization device.

Background

The traditional catheter is a straight-through normally open type and is designed into various diameter specifications according to the size of a urinary tract. The direct connection and the normal opening are that the catheter is directly inserted into the bladder and fixed to prevent falling off, the function of the patient for independently discharging urine is suspended, and the catheter discharges the urine. The catheter with various diameter specifications is convenient to pull and insert, and the discomfort of a patient is reduced. Because urine is discharged through the catheter inner hole, the urine bag is an indispensable spare part, and the life burden of a patient is increased. In addition, urine is often missed due to the poor seal.
