Urine leakage prevention type indwelling catheterization device

Abstract

The invention relates to the technical field of medical instruments, in particular to a urine leakage prevention type indwelling catheterization device which comprises a connecting piece, a clamping piece, a locking piece and a buffering piece, the buffering piece is clamped at one end of the connecting piece, a through hole is formed in the buffering piece in the axial direction of the buffering piece, the clamping piece is coaxially installed in the connecting piece, and the clamping piece comprises a cylindrical surface section and a conical surface section; the small end of the conical surface section is connected with the cylindrical surface section, a clamping hole is formed in the clamping piece, a plurality of contraction joints are formed in the side wall of the clamping piece, the middle of the conical surface section abuts against the inner edge of the end of the connecting piece, the locking piece is connected with the connecting piece in a threaded fit mode, and a pressing ring is arranged at the end, away from the connecting piece, of the locking piece and abuts against the end face of the large end of the conical surface section. Urine leakage caused by the fact that the ureter cannot be tightly attached to the inner urethral orifice is avoided, growth and reproduction of bred bacteria are avoided, the infection rate of the urinary system and the incidence rate of incontinence dermatitis are reduced, conditions are provided for the bacteria to retrograde to the bladder along a gap between the urethra and the ureter, physiological and psychological pains of a patient are relieved, and the workload of nurses is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-leakage type indwelling urinary catheterization device. Background technique [0002] A catheter is a tube that is inserted through the urethra into the bladder to drain urine. It is a pipeline made of natural rubber, silicone rubber or polyvinyl chloride (PVC), which can be inserted into the bladder through the urethra to drain urine. A urinary catheter remains in the bladder, and a drainage tube is connected to a urine bag to collect urine. [0003] The double-lumen balloon-type indwelling catheter is commonly used in clinical practice, but it has a high probability of urine leakage. During the indwelling catheter in critically ill and elderly patients, the urethral sphincter atrophy, the pelvic floor muscles and the urethral sphincter relax, resulting in the urinary catheter and the urethra. The mouth cannot be closely attached, resulting in leakage of urine,...

Problems solved by technology

[0003] The double-chamber balloon indwelling catheter is commonly used clinically, but it has a high probability of leakage of urine. During the indwelling catheter in critically ill and elderly patients, the urethral sphincter atrophy, pelvic floor muscle and urethral sphincter relaxation, resulting in the catheter and urethral The mouth can not be close, resulting in leakage of urine, so that the urethral orifice is in a humid environment for a long time, the growth and reproduction of bacteria, increasing the incidence of urinary system infection and incontinence dermatitis; , will also cause bacteria to retrograde along the urethra and urinary catheter space to provide conditions for the bladder, which not only increases the physical and psychological pain of the patient, but also increases the workload of the nurses
