Abstract

The utility model discloses an external marked computer cell counting board, which is mainly used for microscopically counting cells and particles in medicine test. The external marked computer cell counting board comprises a base board and a counting cell cover plate, wherein, a counting cell mirror face and a cell height holding table are arranged on the base board; the counting cell mirror surface is a smooth plane without grid; a liquid adding pool is opened on the counting cell mirror surface; the counting cell cover plate is fixed on the cell height holding table compared with glass counting boards widely used, the external marked computer cell counting board has the advantages of accurate counting results, low manufacturing cost, disposable usage, safety, sanitation, etc. The utility model is an upgrade and generation-replacing product of the glass counting boards.

Description

External standard formula computer cell counting count board

The utility model relates to a kind of external standard formula computer cell counting count board, is mainly used in the microscopic count of pair cell and particle in the work for inspection.

In medical laboratory work to countings such as red blood cell, leucocyte, blood platelet, sperms, extensively adopt glass counting count board, the counting chamber cover plate of this tally can separate with substrate, can be repeatedly used, but glass counting count board exists the counting grid directly to be engraved on the counting chamber minute surface, and the degree of accuracy of counting grid is difficult to guarantee; Counting region is little and fixing, and only 9 square millimeters, count results representative relatively poor; When being to use, the counting chamber cover plate is placed on the high saddle in pond temporarily, dust and filament easily are clipped between the high saddle of counting chamber cover plate and pond, make the counting chamber height produce problems such as error, influenced the accuracy of glass counting count board count results, cost is higher simultaneously, be repeatedly used and also allow tally carry various pathogen easily, prestige is assisting that the work for inspection personnel's is healthy.

It is wide that the purpose of this utility model provides a kind of counting region, and the counting chamber height is accurate, and count results is accurate, do not carry pathogen, cheap external standard formula computer cell counting count board.

For achieving the above object, the utility model comprises substrate and counting chamber cover plate, on substrate, have the step trough of symmetry, the counting chamber minute surface is formed in the bottom surface of step trough, the ladder of counting chamber minute surface both sides is formed the high saddle in pond, the high saddle in pond is parallel with the counting chamber minute surface, and the counting chamber minute surface is smooth no grid plan, and the counting chamber cover plate is fixed on the high saddle in pond.

Described external standard formula computer cell counting count board has liquid-adding cell on the counting chamber minute surface, the part of this liquid-adding cell is counted the pond cover plate and covers.

Described external standard formula computer cell counting count board, end face is higher than end face on the counting chamber cover plate that is fixed on the high saddle in pond on the substrate.

Because the counting chamber minute surface of the utility model computer cell counting count board is smooth no grid plan, the counting grid is the standard counting size beyond this external standard formula computer cell counting count board, this standard counting size comprises independent standard length or standard grid, also comprise stickup or be printed on standard length or the standard grid beyond the counting chamber minute surface on the utility model external standard formula computer cell counting count board, therefore, arbitrary region can be counted in whole counting chamber scope, enlarged counting region, guarantee that easily count results is representative, and avoided the error of counting grid, and the counting chamber cover plate is fixed on the accuracy that has also guaranteed the counting chamber height on the high saddle in pond, therefore, the utility model external standard formula computer cell counting count board has count results more accurately than existing widely used glass counting count board; In addition, owing to do not need delineation counting grid, the manufacturing cost of the utility model external standard formula computer cell counting count board is reduced greatly, have cheap price advantage, thereby can disposable use promptly change, avoided being repeatedly used the worn-out end of portable various pathogen.

An embodiment of the present utility model now is described in detail in detail in conjunction with the accompanying drawings.

Figure 1 shows that the utility model external standard formula computer cell counting count board schematic perspective view.

Fig. 2 is the vertical view after shown in Figure 1 external standard formula computer cell counting count board removes the counting chamber cover plate.

As shown in the figure, the middle part has step trough on substrate [1], counting chamber minute surface [5] is formed in the bottom surface of this step trough, on counting chamber minute surface [5], have " H " type isolation channel [3], isolation channel [3] is divided into two counting chambers with counting chamber minute surface [5], also design has liquid-adding cell [4] on each counting chamber, the part of liquid-adding cell [4] is in the scope that counting chamber cover plate [6] covers, the ladder of counting chamber minute surface [5] both sides is formed the high saddle in pond [2], the high saddle in pond [2] is parallel with counting chamber minute surface [5], counting chamber cover plate [6] is fixed on the high saddle in pond [2], and at this moment, substrate [1] is gone up end face and is higher than upward end face of counting chamber cover plate [6].Before the use, earlier standard is counted size and put into the counting grid that the microimaging camera lens that is connected with computer is calibrated computer program down, to drip this external standard formula computer cell counting count board that test liquid is arranged then and put under the same microimaging camera lens, can from computer, calculate assay.

The counting chamber minute surface of the utility model external standard formula computer cell counting count board can be separated into a plurality of counting chambers by isolation channel, opens liquid-adding cell on each counting chamber.
