Problems solved by technology

The first type of constant pressure air source needs to be equipped with a set of air source and its pressure stabilizing device, the system is complex and the cost is relatively high
In the second type, each syringe needs to be driven by a separate set of motor and its driving transmission. Since the overall cost of the motor and the supporting driving transmission is relatively high, the cost of this solution is also high

Abstract

The invention relates to the technical field of human blood detection and discloses a flow cytometry fluid path system. The system consists of a motor drive sample stream injector and a sheath fluid injector, wherein the outlet of the sample stream injector is respectively connected with a diluent bucket and a sample injection port by virtue of a pipeline and a three-way solenoid valve and is also connected with a reaction tank; the outlet of the sheath fluid injector respectively passes through a two-way solenoid valve by virtue of a pipeline and a liquid pressure sensor and is connected with a flow chamber sample injection port, a flow chamber sheath fluid injection port and a fluid suction port of the sample stream injector; a hemolytic agent injector is driven by the motor, and the outlet of the hemolytic agent injector is respectively connected with a hemolytic agent bottle and the reaction tank by virtue of a pipeline and a three-way solenoid valve; the outlet of a sampling injector is connected with a sampling needle by virtue of a pipeline; and a diluent injection port in the sampling injector is connected with the diluent bucket by virtue of a pipeline. The system disclosed by the invention is simple in structure, low in cost and simple and reliable in detection method, the detection data is accurate, and machine miniaturization can be realized.

Description

technical field [0001] The invention relates to the technical field of human blood detection, in particular to a flow cytometry detection fluid circuit system and a flow cytometry detection method. Background technique [0002] Sheath flow technology, also known as flow cytometry, uses a capillary to align with a small hole in the detection tube, and the cells or particles to be tested are ejected from the capillary to form a sample flow. At the same time, the sheath fluid (a clean liquid that does not interfere with the test results) flowing out of the capillary wraps the sample flow and flows quickly through the detection area, and ensures that the cells or particles are arranged in a single line in the middle of the detection area. The fluid circuit system for flow cytometry is a fluid system applied to medical blood cell analysis instruments, and it is the control carrier for flow cytometry. Flow cytometry refers to the fluid control technology that controls cells or pa...
