Technical Field
[0001] The utility model relates to the technical field of urinary catheters, in particular to a leakage-proof urinary catheter for urinary care. Background Art
[0002] A urinary catheter is a tool used by patients who cannot take care of themselves to urinate. The tube is straight throughout, and there is a hole at the end to extract the accumulated urine in the bladder. After the catheter is inserted, liquid can be injected into the balloon to expand it to prevent the catheter from slipping out, but the outlet of the urethra is prone to leakage.
[0003] Ordinary urinary catheters lack a leak-proof structure. During the insertion process of the catheter, urine is easily leaked due to friction in the gaps, and then drips onto the mattress or contaminates the medical environment. Frequent replacement of pads also consumes manpower and material resources. Therefore, the leak-proof ability of the urinary catheter should be improved.
[0004] Now, a novel urinary care leak-proof catheter is proposed to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a leak-proof urinary catheter for urinary care, so as to solve the problem of easy urine leakage mentioned in the above background technology.

Then, the release paper is torn off from both sides to expose the adhesive layer on the surface of the nanopatch and stick it to the private part to prevent urine from leaking out. If it needs to be peeled off, pinch the tear strips on both sides to easily remove the leak-proof structure, and then extract liquid from the side tube port to allow the water bag to shrink and slide out;
[0014] (2) By fixing a cylinder on the right side of the urine bag, after removing the catheter, wrap it with a nano-strip, and slightly pressing the hinged rotary block at the lower right corner to facilitate the insertion of the catheter and other objects into the waste storage chamber, and then rotating the rotary block to clamp the catheter from the bottom of the waste storage chamber with the pressing block, it can also prevent the catheter and other medical waste from falling when carrying the urine bag and walking, thus ensuring the cleanliness of the surrounding environment and preventing urine from splashing;

At this time, the pressure ring and the limiting ring are clamped to the outside of the catheter on the left and right and squeezed and locked to prevent urine from being shaken out when the urine bag is moved. If the pressure ring and the limiting ring need to be separated, just remove the card block. BRIEF DESCRIPTION OF THE DRAWINGS
