Urinary catheterization unit

Abstract

The utility model provides a urine catheterization device which comprises a urinary catheter, a drainage tube and an auxiliary sealing element. A urine inlet and a urine outlet are formed in the urinary catheter body. The end, close to the urine inlet, of the urinary catheter body is the inserting end, and the end, close to the urine outlet, of the urinary catheter body is the discharging end. The discharging end of the urinary catheter body is used for being communicated with the connection end at the top end of a drainage tube body, and the tail end of the drainage tube body is communicated with a container for storing urine. The auxiliary sealing element is used for containing the discharging end of the urinary catheter and the connection end of the drainage tube, isolating the discharging end and the connection end from the outside and sealing the discharging end and the connection end. According to the urine catheterization device, the auxiliary sealing element solves the technical problem of pollution to the connection position between the urinary catheter and the drainage tube and can effectively isolate the connection position from the outside and seal the connection position, a urine bag can be replaced conveniently, and the connection position is still in the seal and protection state after the urine bag is replaced again.

Description

technical field [0001] The invention relates to a catheterization device, which is used for drainage of urine in human bladder, and belongs to the technical field of medical equipment manufacturing. Background technique [0002] Urinary catheterization has been used clinically for a long time, and it is widely used in surgical procedures and in the treatment of urinary retention caused by various urinary tract obstructions. Specifically, when clinically nursing patients with urine drainage, the drainage device used is composed of a catheter, a drainage tube, and a urine container. The hollow inner cavity of the catheter communicates the inner cavity of the bladder with the outside world, and The urine is exported through the catheter and the drainage tube and then stored in the connected urine container, thus forming a relatively closed urine export and storage system. At present, the urinary catheter and the drainage tube are not connected before use, and the two are plugg...

AI Technical Summary

Problems solved by technology

At present, the urinary catheter and the drainage tube are not connected before use, and the two are plugged in or threaded during use. The contamination of pathogenic bacteria, and the urine test of catheterized patients is more frequent clinically, and the connection between the catheter and the drainage tube needs to be opened many times to collect urine. The connection will lead to contamination of the connection and further cause ascending infection of the human bladder; on the other hand, according to the relevant nursing routine, the replacement frequency of the urine container is higher than that of the catheter, and a new sterile urine When the container is connected to the end of the contaminated catheter through the drainage tube, it will be contaminated immediately, which will further increase the risk of ascending bladder infection in humans

[0003] In order to solve the above-mentioned technical problem of contamination of the joint between the catheter and the drainage tube, medical device developers urgently need to develop a device that can not only effectively isolate and seal the joint from the external environment, but also facilitate the replacement of the urine container, and re-use it. Catheters in which the connection remains sealed and protected after the urine container has been replaced
