Description

TECHNICAL FIELD

[0001] The present application relates to the field of bladder perfusion technology, in particular to a bladder timed perfusion device and system. BACKGROUND

[0002] In the medical field, bladder perfusion as a common treatment method is widely used in the treatment of bladder diseases (such as cystitis, urinary tract infection, etc.). The traditional bladder perfusion method mainly relies on manual operation, and the liquid flow rate, flow and temperature are manually controlled by medical staff. This operation method is not only easily affected by human factors, but also has problems such as inaccurate liquid perfusion, poor treatment effect, complicated operation, etc. In addition, real-time monitoring and adjustment of liquid temperature, flow, liquid level during bladder perfusion also require complex operation and equipment support.

[0003] With the development of medical technology, how to realize the automation and precision of the bladder perfusion process and the personalized needs of treatment has become a key problem to improve the treatment effect and reduce the burden of medical staff.

[0004] After searching, there are some bladder perfusion devices in the prior art, such as:

[0005] 1) The patent application with publication number CN119633241A discloses a spraying type bladder perfusion device. In this patent application, a gas bag is arranged on the inner side of the perfusion pipe body near the end, a liquid spraying bag is sleeved on the outer side of the perfusion pipe body, a liquid spraying bag is arranged in the liquid spraying bag, a solid latex head is fixedly installed at the end of the perfusion pipe body, a liquid pipe tower joint is connected to the side of the perfusion pipe body through a liquid pipe, and the liquid pipe is connected to one end of the liquid pipe passage. The present application can uniformly spray the liquid in the bladder by adding the inflatable gas bag to support the liquid spraying bag on the outer side of the perfusion pipe body, and by means of the tower joint, the chemotherapy drugs are prevented from spilling, thereby avoiding drug waste and chemotherapy drug pollution. By injecting air to increase the pressure, the drugs can form a spray through the conical valve type distribution holes, the gas and liquid are mixed to increase the contact area with the bladder mucosa, and the treatment purpose is effectively achieved. After the drug injection is completed, a certain amount of gas is injected to make the drug in the perfusion device reach the bladder, thereby maximizing the treatment effect of the drug.

[0006] 2) Patent application CN115607815A discloses a temperature-controlled urinary catheter and infusion device suitable for bladder infusion. In this patent application, it includes a heating component to heat the drug solution, a drainage component to discharge the drug solution, and a catheterization component including a housing, a liquid inlet pipe connected to the heating component, and a recovery pipe connected to the drainage component. The liquid inlet pipe has spray holes on the housing, and the recovery pipe has recovery holes on the housing. The drug solution is preheated by the heating component, and when used, the catheterization component is inserted into the patient's bladder. The liquid inlet pipe in the housing delivers the drug through the spray holes to achieve full infiltration of the bladder wall. During the process, the drug solution is circulated to the heating component through the recovery holes and the recovery pipe. The patient does not need to adjust his / her position, avoiding additional pain.

[0007] 3) Patent application CN221490952U discloses a disposable pulse-type automatic alarm pressure-controlled constant-temperature bladder infusion device. In this patent application, it includes a tube body, a urinary catheter head installed at one end of the tube body, and a pressure sensor installed near the urinary catheter head. The device uses a pressure sensor, a pressure alarm light, and a heater to better control and judge the pressure in the bladder during infusion, and can heat the irrigation fluid to avoid stimulating the urethra with cold liquid, causing patients to shiver during infusion. When the urinary catheter head is inserted, the spiral pulse massage head automatically opens for pulse massage, reducing patient pain.

[0008] Although the above-mentioned patents provide different solutions for bladder infusion devices, there are still some limitations and unsolved problems, mainly including:

[0009] Lack of real-time monitoring and feedback mechanism: In many existing devices, although some devices can heat the drug solution and control the flow of the drug solution, there is a lack of real-time monitoring of the flow, level, and temperature of the drug solution. For example, the infusion device in CN115607815A can heat the drug solution, but the temperature control and infusion fluid flow are not accurately monitored and adjusted, which may lead to unstable temperature or drug solution flow that does not meet the treatment requirements, increasing the risk of patient discomfort or treatment failure.

[0010] Manual control and inaccuracy: Some bladder infusion devices in existing technology still rely on manual or semi-automatic control of liquid flow, temperature, and other parameters. For example, the spray-type bladder infusion device in CN119633241A improves drug distribution in the bladder by adding an air bag and a drug solution spraying bag, but the flow, spraying accuracy, and temperature of the drug solution still need to be adjusted manually or by traditional methods, which is easily affected by human factors.

[0011] Deficiency of waste liquid recovery and waste liquid monitoring: Although some bladder perfusion devices involve the recovery of the drug solution, the design of waste liquid monitoring and recovery is still insufficient. How to efficiently and accurately recover the drug solution and ensure the effective discharge of waste liquid is a challenge.

[0012] Insufficient multifunctional integration and intelligent level: The current equipment has low multifunctional integration, and many devices have single function. How to integrate temperature control, liquid level monitoring, flow control, waste liquid recovery, data storage and analysis, and other functions into one, and automatically adjust through an intelligent system to improve the treatment effect and use convenience of the equipment, is still a problem to be solved.
