Flushing fluid for collecting leukocyte or monocyte and collecting device

Abstract

The invention discloses a flushing fluid for collecting leukocyte or monocyte and a collecting device; the flushing liquid is prepared from sodium chloride, potassium chloride, sodium citrate, monosodium phosphate, glucose, albumin, and mannitol, wherein every 1000 ml protection liquid contains 7.02-8.95 g of sodium chloride, 0.13-0.21 g of potassium chloride, 2.52-3.57 g of sodium citrate, 3.80-5.25 g of monosodium phosphate, 3.05-4.25 g of glucose, 20-32 g of albumin, and 3.22-4.02 g of mannitol; after mixing the components, distilled water is filled in 1000 ml volumetric flask and distilled to 1000 ml. the flushing fluid has similar plasma environment, pH environment and nutrient components as plasma, and is good for prolonging the survival time of the collected leukocyte or monocyte, and also can promote the collection amount of leukocyte or monocyte; the collecting device is simple in structure, and can collect leukocyte or monocyte on line; the collection efficiency is up to 90%; the survival rate is up to 80%; the blood after collecting can be stored or re-transformed to its main body; thereby effectively avoiding blood waste.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a washing liquid for collecting white blood cells or mononuclear cells and a collection device. Background technique [0002] As we all know, white blood cells, formerly known as white blood cells, are also called immune cells. They are a type of cells in the blood. They can help the body resist infectious diseases and foreign things as part of the immune system. They are an important blood cell in the blood. They are colorless under a microscope The nucleated cells are generally spherical in shape. According to the difference in shape, it can be divided into two categories: granular and non-granular. Granulocytes (granulocytes) that contain specially stained granules that can be distinguished by staining with Wright's stain are three types of granulocytes: neutrophils, eosinophils, and basophils; agranulocytes include monocytes cells and lymphocytes. The defense and...

Problems solved by technology

At present, in order to ensure the safety of clinical blood use and avoid blood transfusion reactions, people usually filter the leukocytes in the blood before transfusion, and most of the filtered leukocytes are discarded by people, and they are extracted clinically to treat malignant tumors and blood diseases. When the basal cells of immune cells such as diseases, the amount of basal cells obtained by traditional methods is small and the activity is low, and the blood after extraction of basal cells cannot be preserved and used or reinfused into the body, resulting in a great waste
