Abstract

The utility model provides a novel trough dyeing device provided with a base plate. Two sides of the base plate are longitudinally provided with liquid shielding strips to form a dyeing trough whose one end can be made into a flat funnel shape for recovering dyeing liquid; the front parts of the liquid shielding strips are also provided with smear blocks. The trough dyeing device is used with a method that the surface with a sample of the smear is downward covered on the dyeing trough, and the dyeing liquid is filled in a gap between the dyeing trough and the smear for dyeing. The utility model overcomes the problem that microscopic examination difficulties caused by the color dregs of dyestuff or the surface film of the dyeing liquid adhered on the smear influence microscopic examination results.

Description

Dyeing device

The utility model relates to the stain kit technical field that supplies laboratory and hospital inspection to use, and is particularly suitable for the dyeing to smear.

In the medical test technology, be one of technology of very important and widespread usage to the dyeing of smear.In-house positive ion such as cell or bacterium or negative ion can with corresponding dyestuff in have a color negative ion or positive ion combine, make tissue catch color so that microscopy, the quality of dyeing quality directly influences microscopy result's accuracy.Existing staining technique mainly is that dye liquor is directly dripped on smear, or smear is put into staining jar dye, and these two kinds of staining techniques all have certain limitation, are difficult to overcome dye dreg or dye liquor surface film attached to a difficult problem that causes difficult microscopic on the smear.

The purpose of this utility model provides novel slot type stainer and solves dye dreg or dye liquor surface film attached to a difficult problem that influences dyeing quality on the smear.

Slot type stainer described in the utility model has a substrate, is characterized in being vertically arranged with liquid blocking strip and forming a staining trough in the both sides of substrate.

Slot type stainer described in the utility model design proposal preferably is, an end of staining trough can be made into the plane funnel-form, and the height of liquid blocking strip is 0.5～1.0mm.

The better design proposal of slot type stainer described in the utility model is that the front portion of liquid blocking strip is provided with the smear block.

The also adoptable design proposal of slot type stainer described in the utility model is, is vertically arranged with two liquid blocking strips in the centre of substrate and forms two parallel staining troughs.

Adopt the advantage of slot type stainer described in the utility model to be, (1) dye liquor is arranged in the staining trough under the smear, dye dreg can not be deposited on the smear preparation, guaranteed the clear of coloration result, for some high-resolution chromoscopies, as chromosome examination, X body, when the positive object lens of graininess such as stippled red blood cell and various bacteriums are examined, more can improve accuracy.(2) draw dye liquor middle level liquid with suction pipe, can avoid sucking dye liquor superficial film or bottom residues, the dye liquor in the suction pipe is filled when dyeing in staining trough, the dye liquor expose portion is few, be difficult to dry or the formation rete, can overcome dye liquor rete adhering on smear.(3) the funnelform staining trough in plane helps the recovery that compiles of dye liquor, so that reuse, dye liquor is saved in the cost saving spending, helps clinical examination and applies.(4) if the staining trough made from metal material also can apply to heating dyeing, thermal source is placed below the metallochromy frid, just can heat dyeing, can shorten dyeing time.

With reference to the accompanying drawings slot type stainer described in the utility model is described further.

With reference to Fig. 1～2, the utility model is stated the slot type stainer a substrate 1, is vertically arranged with liquid blocking strip 2 and has formed staining trough 3 in the both sides of substrate 1, and an end of staining trough 3 is preferably made the plane funnel-form, helps the recovery that compiles of dye liquor like this; The height of liquid blocking strip 2 is preferably 0.5～1.0mm, so that under the situation that satisfies the dyeing needs, reduces the consumption of dye liquor; The front portion of liquid blocking strip is provided with smear block 4, and smear 5 slips out damage in the time of can preventing to topple over dye liquor.When the smear quantity of need dyeing more for a long time, can select dual grooved stainer shown in Figure 3 for use, it is to be vertically arranged with two liquid blocking strips 2 again and to form two parallel staining troughs in the centre of substrate 1.The using method of this slot type stainer is, one face down and cover on staining trough 3 what sample was arranged on the smear, can be close to simultaneously according to the smear amount of staining trough length and needs dyeing and to cover several smears, then with exhaling pipe to draw the middle level liquid of required dye liquor, dye liquor is filled in the space between staining trough and the smear, dyes according to time, the step of selected decoration method.During as if employing ordinary stain method, staining trough can be tilted to reclaim dye liquor after the dyeing, it is clean that the water flushing will remain dye liquor again.Specific stain then can be directly with flowing water or the flushing of specific damping fluid.
