Description

Technical Field

[0001] The utility model relates to the technical field of ascites drainage devices, and in particular to a portable ascites drainage device with precise constant speed and quantitative function. Background Art

[0002] The commonly used method of ascites puncture and drainage is to place an abdominal drainage tube and then connect a drainage bag to collect ascites. The speed control of ascites drainage is adjusted by a speed regulator attached to the drainage tube. The principle of the speed regulator is to control the inner diameter of the drainage tube through a pulley-like device to adjust the flow and speed of ascites drainage. This commonly used speed regulator that controls the inner diameter of the drainage tube has many shortcomings. First, the drainage speed can only be roughly estimated by the outflow rate of ascites in the drainage bag, which is highly subjective and has large errors. Secondly, its drainage speed is related to the intra-abdominal pressure. The drainage speed will change due to changes in the intra-abdominal pressure, resulting in the daily ascites drainage target volume not being easy to achieve. In addition, sometimes when drainage is not smooth, it cannot be discovered in time, resulting in delayed ascites drainage and affecting the treatment effect. The most important thing is that for patients with decompensated cirrhosis, their internal environment is already seriously disordered. After the occurrence of diuretic-resistant ascites, uncontrolled rapid ascites drainage is likely to aggravate the condition. For example, a large amount of ascites drainage in a short period of time will lead to further disorder of the internal environment and a sharp drop in intra-abdominal pressure, which will in turn aggravate the further production of ascites, circulatory failure, renal damage and other consequences.

[0003] Therefore, for patients with decompensated cirrhosis, after a large amount of ascites effusion occurs, accurately controlling the drainage speed and amount of ascites is a very important part of treatment, which is likely to affect the patient's condition, prognosis, mortality rate, etc. Therefore, it is necessary to design a drainage device with precise speed and quantity for ascites drainage, which can accurately control the speed and amount of ascites drainage, has great advantages and broad application prospects. And this precise speed and drainage volume control can effectively implement clinical research on the impact of ascites drainage speed on the patient's internal environment, and further explore related clinical effects.

[0004] An ascites drainage device disclosed in the publication number CN220344823U comprises a bottom plate, a lifter is fixedly connected to the upper end of the bottom plate, a lifter is dynamically connected to a lift shaft, a lift shaft is fixedly connected to a drainage box, a motor cavity is arranged in the drainage box, a placement cavity with front and rear openings is arranged at the lower end of the motor cavity, a support plate is fixedly connected to the left and right end walls of the placement cavity respectively, a negative pressure device is fixedly connected to the lower end wall of the placement cavity, a collector can be placed on the support plate, the collector has upper and lower openings, and a drainage module is fixedly arranged on the left end wall of the placement cavity; symmetrical baffles are respectively arranged at the front and rear ends of the motor cavity, and the collector can be conveniently installed and disassembled by the negative pressure device and the installable collector, and the collected ascites can be more conveniently stored and destroyed uniformly after the patient drains the ascites by installing and disassembling the collector; the two baffles can block the collector when the patient drains the ascites to avoid the collision of the collector to drive the puncture needle to shake and prevent the puncture needle from being taken out of the patient.

[0005] However, the ascites drainage device has the following disadvantages: when drainage is poor or the set total drainage volume target is reached, it is not easy to give an alarm, which makes it inconvenient for medical staff, patients or family members to discover and deal with the problem in time, and it is easy to delay ascites treatment; when in use, it is not easy to drain smoothly, thereby reducing the impact of the patient's intra-abdominal pressure, and it is easy to produce drastic changes; it is not convenient for patients to carry it with them during daily activities.
