Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely is dialysis machine pipeline and dialysis machine of preventing air from entering. BACKGROUND

[0002] Hemodialysis is a common treatment method, and is widely applied to kidney function substitution treatment of patients. Waste and excess liquid in blood are removed through an artificial method to maintain electrolyte balance and acid-base balance in the body.

[0003] Due to the sensitivity difference of dialysis machines and system metering problems, liquid bags are often empty, and air enters if not replaced in time. On the other hand, the input end pipeline is not smooth, and blood is difficult to draw, which leads to air entering the input end. After the air enters, it is driven by the blood pump and flows into the backflow end (venous jug and backflow pipeline) with the blood. When the air in the liquid flowing from the venous jug to the backflow pipeline is detected by the air detector, the machine backflow pipe clamp automatically clamps the backflow pipeline, and the dialysis treatment is interrupted. The pipeline used in the current dialysis machine has certain airtightness and integrity, and it is difficult to discharge the air, even if it is forced to discharge, it takes a long time, which leads to machine coagulation being forced to get off, delays treatment, increases patient cost and nurse workload.
