Description

Technical Field

[0001] The utility model relates to the technical field of urinary care, and more specifically, to a leakage-proof urinary catheterization device for urinary care. Background Art

[0002] Catheterization is a very basic clinical procedure and is widely used in urology. A urinary catheter is a tube made of natural rubber, silicone rubber or polyvinyl chloride that is inserted through the urethra into the bladder to drain urine.

[0003] For patients with various urinary problems who are bedridden, urinary catheterization equipment is required during the treatment process. Traditional urinary catheterization equipment is difficult to fix the urine bag after the catheter is inserted into the patient's bladder, and urine leakage is likely to occur when the patient turns over, stands up, or walks.

[0004] The Chinese patent application number CN202023188157.1 discloses a leak-proof catheterization device for urological nursing care, comprising a fixing strap, a Velcro strap provided on the front of the fixing strap, a fixing rod fixedly connected to the lower surface of the fixing strap, a fixed tube box movably connected to the bottom end of the fixing rod, and a box cover movably connected to the lower surface of the fixed tube box via a movable shaft. The leak-proof catheterization device for urological nursing care is easy to fix to the patient's body by providing the fixing strap and Velcro strap. By providing a storage pocket, a urine bag can be placed in the storage pocket to fix the urine bag, preventing the urine bag from falling off the patient when the patient turns over, stands up, or walks, thereby avoiding urine leakage.

[0005] However, it can be seen from the drawings in the specification that the connection between the drainage tube and the urine bag is directly fixed by a connector. When the patient turns over, stands up, or walks, the connection between the drainage tube and the urine bag will be stretched, which can easily cause the connection to loosen, causing the urine inside the urine bag to flow out through the connection, resulting in urine leakage, which affects the use effect.

[0016] The technical effects and advantages of this utility model are:

[0017] 1. The present invention first connects the threaded tube at one end of the drainage tube to the threaded insertion rod through the buffer connection mechanism. When the drainage tube drives the threaded tube to be pulled, the threaded insertion rod can be brought into the internal limit ring to squeeze the first spring, thereby performing buffering and preventing the connection from loosening and affecting the sealing effect. At the same time, the second spring pushes the insertion rod to make the sealing pad seal the opening of the fixed tube, thereby preventing the liquid inside the urine bag from flowing back into the middle of the fixed tube and preventing the liquid inside the urine bag from flowing out through the connection, thereby improving the anti-leakage effect.
