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

Embodiment 1

[0040] Such as figure 1 , 3 As shown, a urinary catheterization device includes a urinary catheter 1. The urinary catheter 1 is made of one of natural rubber, silicone rubber or polyvinyl chloride using an injection molding process of an injection molding machine, and is relatively soft as a whole. Good biocompatibility. The urinary catheter 1 has a catheter body 11 with a hollow tube inside. The urinary catheter body 11 is provided with a urine inlet 111 and a urine outlet 112, and one end close to the urine inlet 111 is The insertion end 12 is provided with a balloon for fixing the urinary catheter 1 on the insertion end 12. The balloon is filled with a balloon filling member 14 provided on the catheter body 11, and the end close to the urine outlet 112 is the discharge end 13 The urinary catheterization device also includes a drainage tube 2, the drainage tube 2 is made of polyvinyl chloride material using an extrusion process, the drainage tube 2 also has an internal hollow ...

Embodiment 2

[0048] Such as Figure 8 , 9 As shown, the auxiliary seal main body 33 is provided with a buckle fitting 355, the buckle fitting 355 is in a square convex shape, the auxiliary seal cover 34 is provided with a buckle 354, and the buckle 354 is provided with the aforementioned buckle The square frame of the buckle fitting 355 matching the square protrusions can be sleeved outside the square protrusions, so that the auxiliary seal body 33 and the auxiliary seal cover 34 are in close contact. The auxiliary seal body 33 and the auxiliary seal cover 34 are connected as a whole through a bendable connecting part 353. When the auxiliary seal body 33 and the auxiliary seal cover 34 need to be sealed and buckled, they are bent downward Fold the auxiliary seal cover 34 until the auxiliary seal cover 34 contacts the auxiliary seal main body 33, and then use the force of the buckle 354 to be fixed on the buckle fitting 355 to realize the auxiliary seal main body 33 and the auxiliary seal cov...

Embodiment 3

[0050] Such as Picture 10 , 11 As shown, the connecting portion 353 is specifically a bendable connecting piece, one end is fixed on the auxiliary seal main body 33, the other end is fixed on the auxiliary seal cover 34, and the force applying member 352 is specifically a spring leaf. The spring piece is in a bent state, one end is connected with the end of the connector fixed on the auxiliary seal body 33, and the other end is connected with the end of the connector fixed on the auxiliary seal cover 34. The spring leaf of the force component 352 can exert force to the inner side of the auxiliary seal body 33 and the auxiliary seal cover 34, so that the auxiliary seal body 33 and the auxiliary seal cover 34 are in a sealed state when they are buckled, and the auxiliary seal needs to be opened When the main body 33 and the auxiliary seal cover 34 are bent to a certain angle, the auxiliary seal main body 33 and the auxiliary seal cover 34 are in an open state. In the above-menti...

Abstract

The invention provides a urinary catheter, which includes a catheter, a drainage tube, and an auxiliary seal. The main body of the catheter is provided with a urine inlet and a urine outlet. One end of the liquid outlet is the discharge end, the discharge end of the catheter is used to communicate with the connection end on the top of the main body of the drainage tube, and the end of the main body of the drainage tube is connected to the container for storing urine; the auxiliary seal is used to accommodate the catheter the discharge end and the connection end of the drainage tube, and isolate and seal the discharge end and the connection end from the outside world. The auxiliary seal solves the technical problem of the contamination of the joint between the catheter and the drainage tube. It can not only effectively isolate and seal the joint from the external environment, but also facilitate the replacement of the urine bag. After the urine bag is replaced again, the joint will still remain In a sealed state of protection.

Description

Technical field [0001] The invention relates to a urinary catheterization device, which is used for urine drainage in the human bladder, and belongs to the technical field of medical device manufacturing. Background technique [0002] Catheterization technology has been used clinically for a long time, and it has been widely used during surgery and in the treatment of urinary retention caused by various urinary tract obstruction. Specifically, when performing urine drainage care for patients clinically, the drainage device used is composed of a urinary catheter, a drainage tube, and a urine container. The hollow inner cavity of the urinary catheter connects the bladder cavity with the outside world, Urine is led out through the urinary catheter and drainage tube and stored in the urine container connected to it, thereby forming a relatively closed urine drainage and storage system. At present, the urinary catheter and the drainage tube are not connected before use, and the two a...
