Embodiment 1

[0020] Such as figure 1 The shown blood cell counting board includes a base plate 1 and a cover sheet with a buckle edge. The upper surface of the base plate 1 is provided with four counting pools 2, and the base plate 1 is provided with a buckle groove matching the buckle edge around the counting pools 2. 5; each counting pool 2 is divided into eight counting grids 3 with a volume of 0.1 mm³; two adjacent counting pools are provided with two criss-cross guide grooves 4, one of which runs through the two sides of the bottom plate 1 end; the liquid guide groove 4 and the button groove 5 are connected, and the depth of the liquid guide groove 4 is greater than the button groove 5; the inside of the liquid guide groove 4 is slidably connected with a support column 6, and the support column 6 is formed by

[0021] The "L"-shaped first support column and the second support column are composed; both sides of the support column 6 are connected with a telescopic connecting rod 7, and ...

Embodiment 2

[0024] Such as figure 2 The blood cell counting board shown is different from Embodiment 1 in that the two guide grooves 4 run through the two ends of the bottom plate 1, the support column 6 is a cylinder, and one end of the support column 6 is connected to the two guides. The intersection of the liquid tank 4; the connecting rod 7 is rotatably connected to the support column 6, and a gasket 12 is provided between the connecting rod 7 and the bottom plate 1; the liquid separator 8 is long, and the length of the liquid separator 8 is longer than that of the counting pool The longest diagonal of 2.

[0025] When manufacturing the counting boards in Embodiment 1 and Embodiment 2, the settings of the counting pool 2 and the counting grid 3 can be increased or decreased according to actual needs; the volume of the counting grid 3 can also be changed.

[0026] The difference between the hemocytometer in Example 2 and that in Example 1 is that when the liquid separator in Example ...

Abstract

The invention discloses a blood counting chamber, and belongs to the field of biological equipment. The blood counting chamber comprises a bottom plate and cover glass. Counting pools are arranged on the upper surface of the bottom plate; liquid isolating pieces capable of moving on the upper surface of the bottom plate are further arranged on the bottom plate. According to the scheme, the blood counting chamber has the advantages that redundant sample liquid in the counting pools can be pushed out of the counting pools by the liquid isolating pieces when the blood counting chamber is used, accordingly, the actual volume dose of sample liquid in the counting pools is consistent with the volumes of the counting pools, the problem that the actual volume of sample liquid in existing counting pools is larger than or smaller than the volumes of the existing counting pools can be solved, and the liquid sample counting precision can be improved.

Description

technical field [0001] The invention relates to the field of biological equipment, in particular to a blood cell counting board. Background technique [0002] The hemocytometer is used to microscopically count the red and white blood cells in the human body, and is also commonly used to count the number of some bacteria, fungi, yeast and other microorganisms. It is a common biological tool. Especially in the process of disease diagnosis and treatment, it is often necessary to use a hemocytometer to detect cells in the blood of patients. Counting and classifying cells can provide an important basis for the diagnosis of clinical diseases or the observation of diagnosis and treatment effects. [0003] Currently commonly used blood counting boards include "Niu Bao counting board" and "Fast-read10 quantitative sediment analysis board", etc., taking "Fast-read10 quantitative sediment analysis board" as an example, there are 10 large Squares, each large square has a volume of 0.1 ...
