Problems solved by technology

[0005] On the one hand, the blood treatment equipment currently on the market cannot simulate the physiological environment of the human body to purify the blood. Not only the blood purification ability is insufficient, but also the blood treatment efficiency is low when the pressure is not enough, and the excessive pressure treatment and filtration when the pressure is too high cause blood The destruction of some blood cells or platelets in the blood will seriously affect the quality of the blood returned to the body, so it is urgent to improve the above aspects

Abstract

The invention provides negative pressure blood processing equipment for surgery operations. By setting a processing pipeline, the blood processing equipment can not only simulate the human physiological environment to purify blood, but also effectively remove plasma, air bubbles and suspended impurities in the blood. At the same time, normal saline is supplemented to the blood by exchange, so as to improve the quality of the blood returned and human body comfort after injecting the blood that has extracorporeally circulated to the human body. According to the present invention, simultaneous multiple blood processing steps are realized through the special structure design of the processing pipeline, a hollow casing pipe and spacer columns, and the efficiency of blood processing is improved.

Description

technical field [0001] The invention belongs to the field of blood treatment equipment, and in particular relates to a negative pressure surgical blood treatment equipment. Background technique [0002] As early as the 1970s, there were many documents in the Soviet Union about the exploration of the application of negative pressure to treat refractory wounds and wounds. Negative pressure acts on the cell membrane to expand and distort it. The cells are considered to be damaged and conduct damage. The information to the nucleus, through signal transduction, causes the cells to secrete pre-healing growth factors, including vascular proliferation factors, thereby stimulating the tissue to produce more new blood vessels. Negative pressure suction absorbs the exudation from the wound surface, helps to establish the liquid balance of the wound surface, can provide a moist environment, remove necrotic tissue, reduce the number of bacteria on the wound surface, reduce edema, increas...
