Description

Technical Field

[0001] The utility model relates to the technical field related to hemodialysis, in particular to a shunt external device for hemodialysis. Background Art

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body and exchanges substances through the principles of diffusion, ultrafiltration, adsorption and convection. During the treatment, the blood needs to be shunted externally. However, the existing shunting external devices for hemodialysis still have certain defects when used, such as;

[0003] For example, a shunt external device for hemodialysis with publication number CN208389072U is used. When in use, the threaded interface of the first connecting pipe is connected to the dialyzer connecting tube. When blood clots or impurities appear, the sensor can detect and issue an alarm. At the same time, the information is transmitted to the solenoid valve, which will separate and close from the first connecting pipe. The blood clots or impurities enter the second connecting pipe or the third connecting pipe, thereby blocking the blood clots or impurities and allowing hemodialysis to be carried out without risk until completion. The operation is convenient and the occurrence of adverse events is reduced.

[0004] However, the hemodialysis shunt external device still has the following disadvantages during actual use:

[0005] The presence of blood clots or impurities is monitored by sensors, and the first connecting pipe is then separated and closed. In actual use, after the sensor detects blood clots or impurities, it takes a certain amount of time to notify and execute the separation and closure action. Therefore, some clots or impurities can easily enter the patient's circulatory system, causing adverse effects on the patient. In addition, a complex automation system needs to be designed as a whole to ensure that the separation and closure operation can be performed quickly and accurately when a problem is detected, which increases the complexity and maintenance cost of the equipment.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original hemodialysis shunt external device. Therefore, we proposed a hemodialysis shunt external device that can well solve the above problems. Utility Model Content

In actual use, after the sensor detects the blood clots or impurities, it takes a certain amount of time to notify and execute the separation and closure action. Therefore, some clots or impurities can easily enter the patient's circulatory system, causing adverse effects on the patient. In addition, a complex automation system needs to be designed as a whole to ensure that the separation and closure operation can be performed quickly and accurately when a problem is detected, which increases the complexity of the equipment and the maintenance cost.
