Filtering mechanism for blood therapeutic equipment

Abstract

The invention relates to a filter mechanism used for a blood therapy instrument, which consists of a blood collecting storage box, a blood pump, a filter, a plasma storage box 7 and a pipeline. The filter mechanism is formed by the blood collecting storage box, the blood pump, a centrifugation cup, the plasma storage box, a plasma-returning pump, the filter and a filter pump connected in series by the pipeline in sequence; the blood collecting storage box is provided with a bye path which is communicated with an anticoagulant pump; the pipeline between the centrifugation cup and the plasma storage box is provided with a bye path which is communicated with a drug pump; the filter is composed of five layers of filter membranes in an overlay manner, which are as follows from up to down in sequence: a first membrane layer that is an adsorption-typed deep-layer filter membrane layer which consists of lignin and inorganic silicon; a second membrane layer that is a special deep-layer filter membrane layer which consists of lignin and filter aid on inorganic diatom; a third membrane layer that is an adsorption-typed deep-layer filter membrane layer which consists of lignin and inorganic silicon; a fourth membrane layer that is a special deep-layer filter membrane layer which consists of lignin and filter aid on inorganic diatom; and a fifth membrane layer that is a microporous membrane layer which is made from polypropylene, with the micropore of 0.2 Mum.

Description

technical field [0001] The invention relates to a filter mechanism for a blood treatment instrument, which belongs to the category of medical instruments and is suitable for taking out media from human blood for treatment. Background technique [0002] According to the view of modern medicine, the blood in the human body can transport oxygen, nutrients, hormones, etc. to maintain life and physiological activities to the tissue cells of the whole body; Blood also plays an important role in maintaining the body's acid-base balance, regulating body temperature, and resisting germs. But at the same time, it is also believed that in addition to the above-mentioned positive effects, blood also transfers the infection and disease in local organs of the human body to other healthy parts of the human body along with the operation of blood. Similarly, traditional Chinese medicine believes that qi is the commander of blood, and blood is the mother of qi. Diseases originate from blood,...
