[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: a multi-layer sampling blood smear drying rack, comprising a base 1, and a fixed frame 101 rotatably connected to the base 1; the fixed frame 101 has open sides, which can improve the air-drying effect of the blood smear inside the fixed frame 101, and can effectively prevent the blood smear from being exposed to direct sunlight, thereby improving the drying quality of the blood smear.

[0025] A plurality of fixed grooves 2 are equidistantly provided inside the fixed frame 101, and a pressure plate 201 is slidably connected inside each fixed groove 2. Two springs 203 are connected to the top of each pressure plate 201, and the other end of each spring 203 is connected to the inner wall of the fixed groove 2. The nurse inserts the blood slice to be dried into the fixed groove 2 along the front end of the pressure plate 201, and moves the bottom end of the blood slice against the inner wall of the fixed groove 2. Under the elastic action of the spring 203, the pressure plate 201 can squeeze the blood slice, so that the blood slice is stably placed inside the fixed frame 101.

[0026] A micro motor 3 is connected to the inside of the base 1, and the output end of the micro motor 3 is socketed with the bottom end of the fixed frame 101; when the nurse fixes multiple blood flakes inside the fixed groove 2 respectively, the micro motor 3 can be driven to control the rotation speed of the output shaft of the micro motor 3, so that the fixed frame 101 on the upper part of the base 1 can rotate slowly, thereby driving the air flow inside the fixed frame 101 and accelerating the drying of the blood flakes inside the fixed groove 2.

[0027] Each fixed groove 2 has two slide grooves, each of which is slidably connected to a slide rod 202. Each spring 203 is wrapped around the outer wall of the slide rod 202. By moving the pressure plate 201, the slide rod 202 can be driven to slide inside the slide groove, so that the pressure plate 201 always remains vertical during the movement without being skewed.

[0028] The top of each slide bar 202 is connected to a limit block 204 , and each limit block 204 is slidably connected to the inside of the slide slot. When the slide bar 202 slides in the slide slot, the limit block 204 can effectively prevent the slide bar 202 from leaving the slide slot.

[0029] The front end of each pressing plate 201 is configured to be arc-shaped, which enables the nurse to quickly insert the blood slice into the fixed groove 2, thereby eliminating the need to manually lift the pressing plate 201 and then insert the blood slice into the fixed groove 2, thereby improving the nurse's work efficiency.

[0030] A plurality of connecting plates 4 are equidistantly connected to the inner wall of the fixed frame 101, and a card slot 401 is opened inside each connecting plate 4. When the front end of the blood film is inserted into the fixed slot 2, the blood sample area of ​​the blood film can be placed on the surface of the connecting plate 4, thereby providing a better support for the blood sample area of ​​the blood film. Under the action of the card slot 401, the tail end of the blood film can be inserted into the card slot 401, which can further improve the stability of the blood film when it is placed flat.

[0031] The outer wall of each connecting plate 4 is connected with two connecting rods 402 , and the other end of each connecting rod 402 is connected to the inner wall of the fixing frame 101 . Under the action of the connecting rods 402 , the blood film can be supported.

[0032] A plurality of ventilation slots are provided inside the fixed frame 101, and each ventilation slot is connected to a ventilation net 5. The ventilation slots and the ventilation net 5 cooperate with each other to improve the air-drying effect of the blood sample area of ​​the blood smear, while reducing the phenomenon of foreign matter adhering to its surface.

[0033] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
