Embodiment Construction
[0015] figure 1 It is a schematic diagram of the overall structure of the present invention, figure 2 for figure 1 A schematic diagram of the cross-sectional structure. Depend on figure 1 and figure 2 As can be seen, an inclined blood smear dyeing box includes a dyeing box body 1, a blood smear insertion port 2 placed on the upper end of the dyeing box body 1, and a body cavity 7 with a built-in blood smear, and is characterized in that: The plane of the blood smear in the inner cavity of the body 7 is inclined at an angle of α to the horizontal plane. The upper part and the bottom of the dyeing box body 1 are respectively provided with an upper liquid guide / air guide hole 3 and a bottom liquid guide / air guide hole 4 communicating with the inner cavity of the body. The outlet vertical heights of the upper liquid guide / air guide hole 3 and the bottom liquid guide / air guide hole 4 are higher than the vertical height of the blood smear insertion port.

The invention relates to a tilting blood smear dyeing box, belonging to the technical field of medical equipment. The dyeing box is characterized in that an angle alpha is kept between the blood smear plane of a dyeing box body cavity and the horizontal plane, the upper part and the bottom of the body are respectively provided with upper liquid / gas guiding holes and bottom liquid / gas guiding holes which are communicated with the body cavity, and the vertical heights of the exits of the upper and bottom liquid / gas guiding holes are all higher than that of an insertion opening of a blood smear. The invention has the beneficial effects that: the angle alpha is kept between the blood smear plane and the horizontal plane, thus the blood smear is more convenient to assemble and disassemble, the blood smear can be more fully contacted with a dye solution, and the dyeing quality is improved; the upper part and the bottom of the body are respectively provided with liquid / gas guiding holes, thus the blood smear after being dyed can be washed to be cleaner, the drying efficiency is higher, and the imaging quality of the blood smear is improved; and when the dyeing box provided by the invention is applied to an automatic blood smear manufacturing and dyeing machine, pollution to the dye solution and volatilization of the dye solution can be effectively avoided, the number of times for replacing the dye solution is reduced, the dye solution is saved, and the laboratory environment is protected.
Description
technical field [0001] The invention belongs to the technical field of medical devices, and relates to a blood smear dyeing box used in the blood smear dyeing process, in particular to an inclined blood smear dyeing box. Background technique [0002] Blood smear staining is one of the essential procedures when using a microscope for blood smear analysis. There are two types of dyeing methods: open and closed. Among them, manual staining usually adopts an open dyeing method, which is simple, but consumes a lot of dye solution and exposes a large area, causing the dye solution to volatilize and pollute the environment. Closed staining is usually used in automatic staining instruments. After the blood smear is prepared, it is placed in a relatively closed and independent staining box, and the staining is completed according to the set time and dye solution ratio. Its advantage is to avoid dyeing solution pollution and volatilization. [0003] Existing automated film-making a...
