Safe leakage-proof ureter

Abstract

The invention discloses a safe leakage-proof ureter. The ureter comprises a ureter body, a urine catheterization cavity and a leakage-proof airbag which is sleeved at the front end of the ureter body, wherein a urine inlet communicated with the urine catheterization cavity is formed on the ureter body, and positioned at the front end of the leakage-proof airbag; the leakage-proof airbag is of a conical structure and gradually reduced from the front to the back. The front end of the ureter body is provided with the leakage-proof airbag, and the leakage-proof airbag is designed to be a conical structure, the relatively large part of the leakage-proof airbag can be attached to the internal opening of urethral canal by pulling the ureter body outward when urine is leaked because the internal opening of the urethral cannel is loose and the ureter is not effectively attached to the internal opening of the ureter, so that urine leakage is prevented. According to the safe leakage-proof ureter guarantees more scientific and safer urine catheterization and good leakage-proof effect, so that the incidence rate of complications is effectively reduced, the comfort of a patient in the treatment process is guaranteed, and the safe leakage-proof ureter is simple in structure and low in use cost.

Description

technical field [0001] The invention belongs to the field of medical catheterization, in particular to a safe leak-proof urinary catheter. Background technique [0002] In medicine, catheterization is to insert a catheter through the urethra into the bladder to drain urine. It is mainly divided into two types: retention catheterization and intermittent catheterization. Retention catheterization is a common clinical diagnosis and treatment method, which refers to keeping the catheter in the patient's body all the time, and pulling it out or replacing it with a new tube regularly when the condition permits. [0003] At present, urine leakage often occurs in the process of clinical retention catheterization, especially in elderly patients. Its reason mostly is that the catheter balloon that uses at present can't evenly and tightly seal the internal opening of the urethra. When the internal urethral orifice tissue is relatively tense, it can rely on the retraction of the inter...

AI Technical Summary

Problems solved by technology

Leakage of urine may cause retrograde infection of bacteria through the urinary tract, resulting in an increased risk of urinary system infection. At the same time, it will cause the patient's clothes to be wet and polluted, and the perineum to be soaked in urine. Patient discomfort and perineal skin damage

[0004] The current urinary catheter does not have the function of preventing urine leakage, so when leakage occurs, only external assistance can be used, such as increasing the protection of the perineum or urethral orifice, changing the clothes in time and other remedial measures.

Its operation is cumbersome and wastes manpower and is not conducive to the recovery of patients

[0005] At present, there is a urinary catheter "three-chamber three-bag leak-proof catheter (application number: 01251737.2)" on the market. The leak-proof catheter in this patent mainly includes an inner balloon and two outer balloons. At the same time, it acts to prevent urine leakage, but the structure of the leak-proof catheter is relatively complicated, the cost is high, the volume is large, and the leak-proof effect is not very ideal.
