Description
Technical field
The present invention relates to biological equipment field, more particularly to a kind of blood counting chamber.
Background technology
Blood counting chamber is used to carry out microscopic count to red in human body, white blood cell to be used, and is also commonly used for calculating some thin
The quantity of the microorganisms such as bacterium, fungi, yeast, is a kind of common biology instrument.Especially in disease diagnosis and therapy process
In, generally require to use blood counting chamber to detect the cell in patient in blood, can be with by the counting to cell and classification
For clinical disease make a definite diagnosis or the observation for the treatment of effect provides important evidence.
Current commonly used blood counting chamber has " ox Bao tally " and " the quantitative sediment analysis plates of Fast-read10 " etc.,
By taking " the quantitative sediment analysis plates of Fast-read10 " as an example, 10 block plaids are provided with this tally altogether, each block plaid
Volume is 0.1 μ l, and every block of plate can apply to 10 cell counts of sample.But when cell number is more, work can be caused
Counting of the personnel to block plaid inner cell is difficult, so as to cause result error larger.In view of the situation, at present to " Fast-
The improvement of the quantitative sediment analysis plates of read10 ", is mainly evenly divided into 9 medium squares by each of which block plaid, then by each
Most middle medium square is subdivided into 9 lattices in block plaid, and the cell in 9 lattices is counted under high power lens,
And then the cell number contained in every liter of sample liquid can be extrapolated.
But during the grid injection sample liquid on to tally, artificial drop is taken because injection mode is mainly
Note, the sample liquid of instillation often occurs the situation overflowed grid or do not fill grid, and is according to each block plaid when counting
Volume, so as to cause deviation occur to the counting of sample liquid inner cell, causes the false diagnosis of disease come what is calculated, can be endangered when serious
Health of the evil to patient.
The content of the invention
For above-mentioned technical problem, the invention is intended to provide a kind of blood counting chamber, to solve the tally of prior art
Sample liquid injection rate does not know in grid, causes cell count the problem of deviation occur.
A kind of blood counting chamber in this programme, including base plate and cover plate, the upper surface of base plate is provided with counting chamber；On base plate
Be additionally provided with can thereon surface movement every liquid piece.
The operation principle and its advantage of this programme：Base plate be provided with can thereon surface movement every liquid piece；Use
When, after sample measuring liquid to be checked is injected in the counting chamber on base plate, allow sample liquid to overflow counting chamber a little；Then make every liquid piece in base plate
Upper movement, during being moved every liquid piece, promotes unnecessary sample liquid in counting chamber to move forward every liquid piece, until by unnecessary sample
Liquid is released outside counting chamber, so as to ensure that the sample liquid given volume in counting chamber, it is to avoid the sample liquid actual volume in counting chamber
Amount is more than or less than the situation of counting chamber volume, so as to ensure that the accuracy of sample liquid cell count.During counting, cover plate is put
Put is carried out above counting chamber, and cell count is carried out using microscope, due to the stop of cover plate, it is to avoid microscope and sample liquid
Directly contact, so as to ensure that the accuracy of microscopical health and detection.
Further, the counting chamber is provided with multiple.By setting multiple counting chambers, can be with same blood counting chamber
Multiple different types of sample liquids are detected, so as to improve the detection efficiency of sample liquid.
Further, it is provided with crisscross intake chute between the adjacent counting chamber.By setting intake chute so that every liquid piece
The unnecessary sample liquid released can be discharged by intake chute, it is to avoid sample liquid is piled up on base plate, is polluted.
Further, the cover plate is provided with button along the catching groove for coordinating with button edge around counting chamber.Cover plate is set to carry
Button edge, and coordinate with catching groove, when cell count is carried out, due to being fitted close between button edge and catching groove so that cover plate is close to meter
The top in number ponds, it is to avoid rocking for cover plate, so as to improve the accuracy of counting.
Further, the catching groove is connected with intake chute.Catching groove is connected with intake chute, many in the pushing course every liquid piece
Remaining sample liquid to being flowed into catching groove, then flows out hemocytometer by after liquid piece releases counting chamber by the intake chute connected with catching groove
Number plate, so as to reduce flowing of the unnecessary sample liquid on base plate upper surface, is conducive to keeping the cleaning of tally.
Further, it is described to be provided with through hole every liquid piece.By setting through hole, can be by through hole to injecting sample in counting chamber
Liquid, because the diameter comparative counting pond of through hole is much smaller, and is brought into close contact every liquid piece and base plate, is injected when in counting chamber
Sample liquid fill counting chamber after, can quickly be found by through hole, it is to avoid the waste of sample liquid；And due to unnecessary in counting chamber
Sample liquid content is reduced, and is also beneficial to keep the cleaning of tally.
Further, the side wall every liquid piece is provided with the fin for upwardly extending.Promoting unnecessary in counting chamber every liquid piece
Sample liquid outflow after, after unnecessary sample liquid is excessive, sample liquid can exceed every the upper surface of liquid piece being piled up every the front end of liquid piece, lead to
Cross setting fin so that sample liquid is difficult to be higher by every liquid piece, all the time every the flowing of the front of liquid piece；So as to avoid every the upper of liquid piece
End face is contaminated.
Further, the side wall every liquid piece is provided with absorbent sheet, and the bottom surface of absorbent sheet is higher than every the bottom surface of liquid piece.Pass through
Absorbent sheet is set, when promoting unnecessary sample liquid to flow every liquid piece, when the sample liquid in front of liquid piece is stacked into a certain amount of, absorbent sheet
Unnecessary sample liquid is absorbed, reduces sample liquid content, so as to reduce pollution of the sample liquid to base plate.And the bottom surface of absorbent sheet is high
In every the bottom surface of liquid piece so that the bottom surface of absorbent sheet is consistently higher than counting chamber, sample in counting chamber is absorbed so as to avoid absorbent sheet
The situation of liquid occurs, it is ensured that the sample liquid given volume in counting chamber, so as to be conducive to improving the counting precision of sample liquid.
