Pressure measurement noninvasive anti-blocking urine guiding device

Abstract

The invention discloses a pressure measurement noninvasive anti-blocking urine guiding device. The pressure measurement noninvasive anti-blocking urine guiding device comprises a catheter, a bladder pressure measurement module, an internal urethral orifice blocking module, a noninvasive air sac module, a diluted liquid injection module, a sterilization module, a urine storage module and an anti-blocking urine guiding module. The pressure measurement noninvasive anti-blocking urine guiding device is delicate and reasonable in structural design, utilizes the negative pressure suction principle, can still drain urine when a few blood clots and other foreign materials are generated inside the bladder, effectively guarantees the urine guiding and drainage effects, and enables a user to visually know the condition of the pressure inside the bladder through the bladder pressure measurement module and know the urine guiding and drainage effects and the circulation condition of a drainage passage in real time when indwelled in a urethral catheter. The noninvasive air sac module wraps the catheter, can achieve the function of negative pressure suction, and can relieve the pain in urethral catheterization. The sterilization module can sterilize the indwelled catheter for long time, largely reduces the occurrence rate of infection caused by the indwelled catheter, guarantees use safety, prolongs the effective indwelling time, reduces the frequency of replacing the urethral catheter, largely saves medical cost and relieves the pain of patients.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pressure measuring non-invasive anti-blocking urinary catheterization device. Background technique [0002] Hematuria is a common symptom of urological patients, such as urinary stones, tumors, trauma, etc. When the amount of bleeding is large, the concentration of hematuria is high, and the urine tends to be retained in the bladder to form blood clots that block the urinary tract, leading to acute renal failure and life-threatening , often requiring emergency surgery to remove the clot. Therefore, once a large amount of hematuria occurs clinically, emergency treatment is often required. [0003] Although there are some medical device products for anti-clogging urinary catheters, it is not easy to implement and the effect is not exact; for example, three-lumen urinary catheters are currently used in clinical practice for flushing and drainage, and normal saline is inje...

Problems solved by technology

[0003] Although there are some medical device products for anti-clogging urinary catheters, it is not easy to implement and the effect is not exact; for example, three-lumen urinary catheters are currently used in clinical practice for flushing and drainage, and normal saline is injected into the bladder from the water inlet pipe and then diluted Urine is drained through the outflow tube, which can avoid the formation of blood clots in the bladder to a certain extent, but there are still many problems in clinical use: (1) The drainage power of the three-lumen catheter mainly comes from the pressure in the bladder, and the pressure is relatively high. The drainage tube is small, and the lumen of the drainage tube is limited. When there is a blood clot in the bladder, it is easy to block the lumen. The medical staff needs to repeatedly use the syringe to flush, sometimes it takes only a few minutes for the medical staff to flush once, which greatly increases the workload of the medical staff and wastes Medical resources; (2) Negative pressure suction can increase the drainage pressure and enhance the drainage effect, but the current clinical use of drainage tubes is soft, and the tube wall is often collapsed when connected to negative pressure, which cannot be realized; (3) The current clinical use of urinary catheter products The pressure in the bladder cannot be displayed, and for some comatose patients who cannot perceive abdominal distension, medical staff often need to observe closely regularly or even repeat B-ultrasound examinations to understand the drainage effect in the bladder, which also increases the workload of medical staff and wastes medical resources; (4) Some clinical patients require long-term indwelling urinary catheters, but the current use of urinary catheters often requires regular replacement to avoid infection, which undoubtedly increases the pain of patients and wastes medical resources
