Abstract
The utility model discloses a blood cell counting board teaching aid and belongs to the field of teaching appliances. The blood cell counting board teaching aid comprises two mutually-perpendicular main bodies and at least two counting bodies, each main body includes two parallel strip-shaped connecting bodies, and connecting lines are uniformly arranged between the connecting bodies. The blood cell counting board teaching aid is simple in structure, easy in production and very suitable for teaching.
Description
Technical field
The utility model relates to the teaching aid field, relates in particular to a kind of blood counting chamber teaching aid.
Background technology
Blood counting chamber is used to, to use red in human body, that white blood cell carries out microscopic count, also be usually used in calculating the quantity of the microorganisms such as some bacteriums, fungi, yeast, is a kind of common biology instrument.
Blood counting chamber is a special thick type microslide, on microslide, has four grooves to form three platforms.Middle platform is wider, in the middle of it, is separated into two halves by a hyphen groove again, and each respectively is carved with a lattice net above one side of something, and each square grid is divided into nine large grids, and a large grid of central authorities, as counting use, is called count block.The scale of count block has two kinds: a kind of is that count block is divided into 16 medium squares (large grid separates with three lines), and each medium square is divided into 25 lattices; Another kind is that a count block is divided into 25 medium squares (separating with two-wire between medium square), and each medium square is divided into 16 lattices.But no matter count block is any structure, they have a common feature, and count block all is comprised of 400 lattices.The count block length of side is 1mm, and the area of count block is lmm
2, the area of each lattice is 1/400mm
2.After covered, the height of count block is 0.1mm, so the volume of each count block is 0.1mm
3, the volume of each lattice is 1/4000mm
3.
While using the blood counting chamber counting, first to measure the quantity of microorganism in each lattice, then be converted into the quantity of microbial cell in every milliliter of bacterium liquid (or every gram sample).
Yet blood counting chamber need be used under the microscope, comparatively inconvenience in teaching field, as utilize the picture mode teaching, and not only lacking vividness, the teaching process that also seems is uninteresting.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, be applicable to the teaching the blood counting chamber teaching aid.
For achieving the above object, the technical solution adopted in the utility model is: a kind of blood counting chamber teaching aid, it comprises two mutual vertically disposed bodies, at least two counting bodies, described body comprises again the connector of two strips that be arranged in parallel, evenly is provided with connecting line between described connector.
In technique scheme, connecting line adopts soft silk suture, can arbitrarily fold, and reduces the body packaging volume.
Preferred technical scheme, be provided with the through hole matched with described connecting line on described connector.
Preferred technical scheme, be provided with magnetic stripe on described connector.
Preferred technical scheme, described counting body is discoid, on described counting body, is provided with magnet.
Using method: two bodies are adsorbed on blackboard mutual vertically, make each connecting line be staggered to form a plurality of lattices; Put into the counting body in lattice, and the counting body is adsorbed on blackboard.Wherein two orthogonal bodies represent blood counting chamber, and the counting body represents the microorganisms such as red blood cell, white blood cell or bacterium, fungi, yeast.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model is more suitable for teaching, can show vividly and how the microorganisms such as blood cell, white blood cell or bacterium, fungi, yeast be counted.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model component diagram.
Wherein: 1, body; 2, counting body; 3, connector; 4, connecting line; 5, through hole; 6, magnet; 7, magnetic stripe.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment mono-:
As shown in Figure 1, 2, a kind of blood counting chamber teaching aid, it comprises two mutual vertically disposed bodies 1, at least two counting bodies 2, body 1 comprises again the connector 3 of two strips that be arranged in parallel, evenly is provided with connecting line 4 between connector 3.
Be provided with the through hole 5 matched with connecting line 4 on connector 3.
Be provided with magnetic stripe 7 on connector 3.
Counting body 2 is discoid, on counting body 2, is provided with magnet 6.
Connecting line 4 is white soft silk suture, is provided with 21 connecting lines 4 on a body 1, and wherein the 1st, 5,9,13,17,21 connecting lines 4 are red, when two bodies 1 vertically arrange, to form the red square frame of 25 lattice, the little square frame of 16 lattice will be arranged in each red square frame, always have 400 little square frames.
Using method: two bodies 1 are adsorbed on blackboard mutual vertically, make each connecting line 4 be staggered to form 400 lattices; Put into counting body 2 in lattice, and counting body 2 is adsorbed on blackboard; Start teaching explanation.
In the present embodiment, two orthogonal bodies 1 represent blood counting chamber, and counting body 2 represents the microorganisms such as red blood cell, white blood cell or bacterium, fungi, yeast.
