[0002] During the dialysis process, the liquid flow on both sides of the dialyzer membrane needs to maintain relative flow stability; however, in outdoor disaster relief, many devices are required, and the power consumption is large. The current power supply is often unstable, which makes the hemodialysis machine prone to instability, especially the liquid flow on both sides of the dialyzer membrane; therefore, in response to this situation, we propose an emergency auxiliary hemodialysis device that can avoid unstable equipment operation and maintain relative flow stability.

[0011] Compared with the prior art, the present application can be driven by a foot-operated pressure mechanism, which can free the operator's hands to better respond to the patient's condition. At the same time, it uses a double-gear reverse transmission to drive the rotating parts and the interference shaft to operate, thereby realizing the relative flow of blood and dialysate, so as to effectively realize blood dialysis treatment, and the components are easy to fold and fix for easy carrying.

In actual preparation, the tooth ratio on the first gear and the second gear and the diameter ratio between the second linkage wheel and the first linkage wheel are set according to the situation, which can effectively control the rotation between the first linkage shaft and the second linkage shaft to ensure that the ratio between the blood flow and the dialysate flow can be controlled to meet the treatment requirements and ensure the stable progress of the dialysis treatment.

When the contact disk and the arc-shaped part conflict, it can push the synchronous belt to operate along the arc-shaped trajectory of the arc-shaped part, so as to effectively complete the circular rotation of the synchronous belt, thereby driving the synchronous wheel to rotate; during actual production and preparation, the staff controls the diameter of the synchronous wheel, the diameter of the arc inside the arc-shaped part, and the specifications of the contact disk, so as to ensure that the contact disk can contact the arc inside the arc-shaped part to drive the positioning shaft to operate, and at the same time the positioning shaft can push the sliding part to move in the moving frame, complete the circular operation of the synchronous belt, and ensure that the synchronous wheel and the synchronous belt can operate.
