Abstract

The invention provides a blood purifier blood loop master clip valve protection cover. The protection cover comprises a clip valve main piece, a clip valve protection cover base, a clip valve protection cover main piece, a clip valve protection cover lid, a steering engine, a clip valve connecting plate, and a clip valve tongue piece, wherein the output shaft of the steering engine is provided with an output gear, the output gear is inserted into the bottom of the clip valve tongue piece and then fixed; the clip valve main piece is fastened with the steering engine through a fixing piece; the clip valve connecting plate, and the clip valve protection cover base and the clip valve protection cover main piece penetrate through a blood purifier box body and are installed together with the clip valve main piece; the clip valve protection cover lid is connected with the clip valve protection cover base through a fine shaft, and a suction device is installed at the portion, corresponding to the clip valve protection cover base, of the clip cover protection cover lid. The blood purifier blood loop master clip valve protection cover is high in clip valve control precision and reliable in control, thus a blood leakage sensor, a bubble sensor and a clip valve are further integrated into one, and thus the treatment process effect and the safety of a patient are guaranteed.

Description

technical field [0001] The invention relates to the technical field of blood purification, in particular to a protective cover for a main pinch valve of a blood circuit of a blood purification instrument. Background technique [0002] Blood purification is to lead the patient's blood out of the body, remove certain pathogenic substances, and purify the blood to achieve the purpose of treating diseases. [0003] Before blood purification, the arteriovenous channel is first established, and the blood at the arterial end is introduced into the plasma separator. After separation, the blood is purified, and then the purified blood is returned to the body through the venous end. [0004] In the process of returning to the human body, when the blood circuit is mixed with air, the patient may experience dyspnea, chest pain, cough, drop in blood pressure, asthma, and severe cases will cause coma and death. At the same time, if the membrane of the dialyzer ruptures and a large amount...
