Abstract

Urinary catheterization is the most common clinical operation. When the urine inlet of the catheter head enters the bladder, and the urine slowly flows out from the catheter into containers such as bends due to the pressure in the bladder, it can be judged at this time After the catheter is inserted successfully, the urine drainage bag connector is inserted into the urine outlet of the catheter to form a closed system. Clinical data show that there is a great risk of infection in this way of making the urine flow out and then connecting the drainage bag connector. The invention provides a flow-stop type urinary catheter, the hydrophobic stop-flow diaphragm at the tail of which seals the inner cavity of the catheter externally and prevents the passage of liquid but not gas, so that the urine does not flow out of the catheter and does not pollute the catheter. On the premise of the urine outlet of the catheter, it can effectively judge whether the catheter has been successfully inserted, so as to minimize and avoid the risk of infection caused by the contamination of the joint between the catheter and the drainage bag.

Description

technical field

[0001] The invention relates to a urinary catheter, in particular to a flow-stop type urinary catheter, which belongs to the technical field of medical instruments. Background technique

[0002] Urinary catheter is the most common clinical medical device. After being inserted into the human body through the urethra, it can drain urine from the bladder to the outside of the body; it can be taken out after one urine drainage, or it can be left in place for multiple drainages for a long time.

[0003] The operation of catheter insertion is usually to use one hand to press the surrounding tissues of the urethral opening to make it relatively fixed, stretch and expose the external urethral opening, and hold the sterile catheter directly or with tweezers, hemostats, etc., from the outside of the urethra. Insert the catheter slowly; when the urine inlet of the catheter enters the bladder, the urine will slowly flow out from the urine outlet of the catheter to the co...
