Embodiment Construction

[0019] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0020] see figure 2 , is a partial cross-sectional schematic diagram of a preferred embodiment of the particle counter of the present invention. The counter includes a front pool part (not marked), a rear pool part (not marked) and a counting assembly 32 arranged between the front pool and the rear pool. The sample liquid containing tiny particles enters from the front pool, passes through the counting assembly 32 and then is discharged from the rear pool, thereby completing particle counting.

[0021] The forebay part includes a forebay housing 17 , a front sheath inlet 18 , a sample needle 20 , a sample needle holder 19 , a forebay cleaning inlet 23 and a forebay 22 . One end of the sample needle exposed outside the forebay includes a sample needle inlet 21 , while the other end inside the forebay includes a sample needle out...

Abstract

The invention discloses a particle counting device. The particle counting device comprises a front pool part, a rear pool part, a counting component arranged between the front pool part and the rear pool part, wherein the rear pool part comprises a rear pool shell, a rear sheath inlet, a capturing pipe, a waste liquid outlet, a rear pool cleaning outlet and a rear pool; the rear pool is formed by an internal cavity of the rear pool shell; the rear sheath inlet is arranged on the rear pool shell and is communicated with the rear pool; one end of the capturing pipe, which is close to the counting component, is provided with a capturing pipe inlet, and the other end of the capturing pipe, which is far away from a technical component, is communicated with the waste liquid outlet; and the rear pool cleaning outlet is arranged at the middle part of the capturing pipe, and is respectively communicated with the rear pool and the waste liquid outlet. The invention also discloses a blood cell analysis device adopting the particle counting device. The particle counting device and blood cell analysis device disclosed by the invention have the advantages of simple structure and high reagent utilization ratio.

Description

technical field [0001] The invention relates to the field of particle analysis, in particular to a particle counting device and a blood cell analysis device suitable for blood analyzers. Background technique [0002] In modern medical systems, it is often necessary to analyze particles in body fluids, especially blood, to obtain various parameters, such as scattergrams of various particles or specific particles, and to count the number of particles (such as cells). Particle analyzers used to analyze and count blood cells or other bodily fluid cells are also commonly referred to as cell analyzers. [0003] The sheath flow impedance technique is a commonly used counting technique in blood analyzers. see figure 1 , is a schematic cross-sectional view of a counter using sheath current impedance technology in the prior art. The counter includes a front tank 3, a rear tank 10, a front tank housing 1, a front sheath inlet 2, a sample needle 4, a sample needle holder 5, a front t...
