Anti-leakage urinary catheterization device

Abstract

The invention discloses an anti-leakage urinary catheterization device, and relates to the technical field of medical instruments, and the anti-leakage urinary catheterization device is characterized in that a collecting cavity is formed in the end part of a urinary catheterization hose, a plurality of liquid inlet holes are formed in the side wall of the collecting cavity, an expansion bag is arranged at the position, close to the collecting cavity, of the urinary catheterization hose, and a catheter, a liquid injection pipe, a lubricating liquid chamber, a branch pipe I and an annular overflow pipe are arranged in the catheterization hose; a branch pipe is arranged on the side wall of the urinary catheterization hose, and a branch pipe II is arranged in the branch pipe; a sealing switch is arranged in the branch pipe II; the end of the catheter is connected with the collecting cavity, the end, away from the collecting cavity, of the catheter sequentially penetrates through the expansion bag and the lubricating liquid cavity, and the end, away from the collecting cavity, of the catheter is located outside the catheterization hose. According to the urinary catheterization device, collected urine can be used for filling the expansion bag, the structure is simple, and operation is convenient; meanwhile, the urinary catheterization device can lubricate the urethra in real time, and the pain of the patient in the urinary catheterization process is relieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to an anti-leakage catheterization device. Background technique [0002] A urinary catheter is a tube inserted through the urethra into the bladder to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC), which can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is a balloon near the tip of the catheter to fix the catheter The tube stays in the bladder and does not come out easily, and the drainage tube is connected to a urine bag to collect urine. [0003] There are following problems in existing catheterization device: [0004] 1. The expansion bag of the fixed catheterization device is often filled with liquid or gas through an external device, which has a complex structure and is inconvenient to operate; [0005] 2. The fixed catheteriza...
