[0054] Such as Figure 1 to Figure 9 As shown, the catheterization device of this embodiment includes a catheter 1, a liquid storage bag 2, and a fixed structure 3 and a disinfection structure 4 arranged on the catheter, specifically:

[0055] The urinary catheter is a section of hollow tube, and the hollow channel of the hollow tube is the catheter channel 5. During catheterization, urine flows through the catheter channel, and one end of the hollow tube is provided with a water inlet connected to the catheter channel. Connector 6, the water inlet connector is a smooth sphere, which can avoid damage to the urinary tract. Multiple water inlets 7 are arranged on the smooth sphere, which are used to introduce urine from different angles. There is a water outlet connector 8 communicating with the catheterization channel, and the inner wall of the water outlet connector is provided with an internal thread 9 connected and fixed with the liquid storage bag,

[0074] The first embodiment discloses a laminated disinfection structure. The disinfection structure in this embodiment is in a staggered form, as shown in Figure 10:

[0075] The urinary catheter of this embodiment is provided with a first notch and a second notch at intervals in the circumferential direction, and the first notch and the second notch are arranged along the entire length of the catheter. The tube body 34 and the second tube body 35 fitted with the second notch, the first tube body is continuously or intermittently provided with a water seepage film I for seeping water into the catheter, and the second tube body is intermittently provided with a water seepage membrane I for seeping water outside the catheter Film II. In this way, the first pipe body and the water seepage membrane I form an inner seepage channel, and the second pipe body and the water seepage film II form an outer seepage flow channel. Of course, in order to realize the flow of disinfectant, the...

Abstract

The invention relates to a urethral catheterization device and a urethral catheterization method thereof, belonging to the technical field of medical instruments. The urethral catheterization device comprises a urethral catheter and a liquid storage bag, and further comprises a fixed structure and a disinfecting structure both arranged on the urethral catheter, wherein the urethral catheter is a hollow tube, and a hollow channel of the hollow tube is a urethral catheterization channel; a water inlet connector is arranged at one end of the hollow tube; the other end of the hollow tube is provided with a water outlet connector communicated with the urethral catheterization channel; the fixed structure comprises a fixed air bag and a manual air adding bag; the disinfecting structure comprisesa disinfectant storage tube and a liquid inlet; the top of the liquid storage bag is communicated with a flow guide head; and a leakage-proof seal is fixed in the water outlet connector. On one hand,the urethral catheterization device has sterilization and disinfection effects and can disinfect the urethra and urine; and on the other hand, the urethral catheterization device is firm in structure, does not leak, avoids flowing-out of residual urine, realizes no leakage during disassembling, pressing or collision, enables a medical environment to be clean, allows medical staff to be pleasant,and provides help for improving the medical care level.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a leakage-free and safe urinary catheterization device and a catheterization method thereof. Background technique [0002] The catheterization device is usually provided with a catheter and a liquid storage bag. The catheter is inserted from the urethra to the bladder to drain out the urine. The fluid storage bag is used for temporarily storing the urine. Urinary catheterization device can well solve the patient's catheterization problem, but there are also some shortcomings: the existing urinary catheter is only a simple export of urine, and there is no sterilization effect, thus: the urinary tract is affected by the length of the catheter When time is stimulated, it is easy to cause infection to the urinary tract, and the exported urine has not been sterilized, which may cause secondary pollution to medical staff or the catheterization environment; at the same time, the...
