Counter and flow-type cell analyzer

Abstract

A counter assembly, sheath flow impedance count device, and flow cytometer analyzer are disclosed.

Description

technical field [0001] The invention relates to a sheath current impedance counting device. Background technique [0002] Sheath flow impedance counting is a technology commonly used in blood analyzers, and the structure of the key component counter is as follows figure 1 and figure 2 shown, where figure 1 is the vertical section of the counter, figure 2 A horizontal section view of the counter. The counter includes a front cell housing 1 , a cathode 2 , a sample needle 3 , a separator 4 , a sample needle base 5 , a rear cell housing 6 , a capture tube 7 and an anode 8 . The forebay housing 1 forms a forebay 17 , and the forebay housing 1 is also provided with a front sheath inlet 9 , a sample liquid inlet 10 and a forebay cleaning inlet 11 all connected to the forebay 17 . The rear pool housing 6 forms a rear pool 18 , and the rear pool housing 6 is opened with a rear sheath inlet 13 passing through the rear pool 18 . The capture pipe 7 is fixed inside the rear tank...

AI Technical Summary

Problems solved by technology

[0007] In this way, there is a problem: on the one hand, the rear sheath should not be actually connected to the front sheath; It enters in the way of dripping, and the outlet also flows out in the way of dripping

The first problem is the liquid level initialization problem, that is, how to ensure that the liquid level is within an acceptable range when the counter is working

The second problem is: due to changes in pressure and temperature, and the impact of droplet dripping, gas will inevitably overflow or dissolve from the liquid, which will cause changes in the liquid level, which may lead to loss of the liquid level during long-term continuous work. control
