example 1

[0060] The difference between Example 1 and Example 2 lies in the way the sample flow is pushed into the flow chamber. Solution 1 is to use a sheath flow syringe to assist in pushing the sample, so that the sheath flow can be quickly formed. The second scheme is that the sheath flow syringe simultaneously pushes the sample and the sheath flow to quickly push the blood sample into the flow chamber 49 .

[0061] Compared with the existing solutions, the immune cell circulation system and applicable method provided by the present invention have the following outstanding advantages:

[0062] 1) The immune analyzer of the present invention can detect small molecule items and be extended to the detection of other items such as bacteria, with high sensitivity and good item expandability;

[0063] 2) Sample pretreatment, sample reaction and sample measurement are integrated in one instrument, which is easy to operate and high in efficiency;

[0064] 3) The detection substance is labe...

Abstract

The invention discloses an immune cytometer fluid system which is characterized by comprising a sample flow and blood collection injection syringe, a hemolytic agent injection syringe, a sampling needle cleaning injection syringe, a sheath flow injection syringe, a sampling needle cleaning tank injection syringe, a blood collection needle, a reagent collection needle, a negative pressure chamber,a blood collection needle cleaning tank, a reagent collection needle cleaning tank, a reaction tank, a reagent storage bin, a flow chamber, a filter, a negative pressure sensor, a waste liquid tank and a diluent barrel, wherein each of the devices are connected through pumps, valves, joints and tubes, to form the complete cytometer fluid system. The immune cytometer fluid system can be adopted todetect small molecule items and expanded to the detection of bacteria and other items, and has the advantages of high sensitivity, good project extensibility, convenience in operation and high efficiency.

Description

technical field [0001] The invention relates to a flow cytometer, in particular to an immune cytometer fluid system. Background technique [0002] Flow cytometry is a modern cell analysis technology for rapid and multi-parameter analysis of suspended cells or particles. Flow cytometry is used to control the blood analysis equipment that cells pass through the detection area one by one. Flow cytometry usually refers to cell flow (also known as For the sample flow) under the wrapping of the sheath fluid, the cells pass through the fluid control technology of the flow chamber detection area in an orderly manner. The probability of missed detection caused by overlapping detection areas. This type of instrument is currently mainly used for cell sorting and quantification. At present, the sample flow of the flow cytometer is generally provided by a syringe, and the power source of the sheath flow is a constant pressure gas source. The advantage of the constant pressure air sour...
