Description

Technical Field

[0001] The utility model relates to the technical field of urinary catheters, and more specifically, to a nursing anti-leakage urinary catheter. Background Art

[0002] Catheterization refers to inserting a catheter into the bladder through the urethra to drain urine. Catheterization is divided into two types: indwelling catheterization and intermittent catheterization. In the former, the catheter is always in the patient's body and is removed or replaced regularly when the condition permits. In the latter, the catheter is catheterized every 4-6 hours and the catheter is removed after the bladder is emptied. Catheters should not be reused, otherwise the user may be infected by bacteria. The procedure for indwelling catheterization is to insert the catheter to an appropriate depth (3-5cm for women and 18-20cm for men), and then insert it 1-2cm after seeing urine flowing out. Then fix the catheter and connect the drainage bag. The specific steps are as follows: ① When laying the catheter tray, put the disposable drainage bag and the balloon catheter into the catheter tray together. ② When performing the catheterization operation, first connect the disposable drainage bag to the balloon catheter, then insert the catheter into the urethra, and insert it 2-3cm after seeing urine. ③ Properly fix it. Advantages: ① It can prevent urine from overflowing and contaminating the bedsheets due to the patient's non-cooperation. ② It can fix the catheter in the shortest time to prevent it from slipping out. ③ It is conducive to the comprehensive treatment of urine. For example, the urine of patients with hepatitis, tumors, etc. can be directly introduced into a disposable drainage bag, which is convenient for centralized treatment and prevents the occurrence of medical cross infection.

[0003] In the existing catheterization device, when the urine is poured out, when the catheter is separated from the urine holding device, the end of the catheter lacks a sealing device, which causes residual urine to flow out of the catheter, causing unnecessary trouble to the personnel. For this reason, we propose a leak-proof catheter for urological surgery nursing to solve the above problem.

[0004] In view of this, research and improvement are carried out on the existing problems, and a nursing leak-proof catheter is provided, aiming to solve the problem and improve the practical value through this technology. Utility Model Content
