DETAILED DESCRIPTION

[0018] Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of protection of the utility model.

[0019] EMBODIMENT

[0020] Please refer to Figs. 1-3 The utility model provides a kind of technical scheme: a medical in vitro diagnosis reagent quantitative preparation system;

[0021] This invention aims to provide a quantitative preparation system for medical in vitro diagnostic reagents with precise proportioning and efficient stirring. Existing medical in vitro diagnostic reagents are prone to proportioning errors and uneven stirring during the preparation process.

[0022] Based on the above issues, the components in this case include a frame 1 and a mixing chamber 2 installed in the middle part of the frame 1. The top of the mixing chamber 2 is provided with a feeding port 3. An electric push rod 4 is provided on one side of the feeding port 3. The output end of the electric push rod 4 is connected to a moving plate 5. A cylinder 6 is provided inside the feeding port 3. Pressure blocks 7 are provided on both sides of the cylinder 6. Assembly grooves are provided on the inner walls of both sides of the feeding port 3. A weighing device 8 is installed inside the assembly groove. The pressure blocks 7 are in close contact with the top of the weighing device 8.

[0023] An opening is provided on the lower side of the feeding port 3, and a sealing plate 9 is inserted into the opening. One side of the sealing plate 9 is inserted into one side of the cylinder 6, and the other side of the sealing plate 9 is slidably connected to one side of the moving plate 5. A stirring motor 10 is installed at the bottom of the frame 1, and a stirring assembly is connected to the driving end of the stirring motor 10. A discharge port 11 communicating with the bottom of the mixing chamber 2 is provided on the lower side of the frame 1.

[0024] The stirring assembly includes an assembly cover 12. A first stirring shaft 13 is connected to the upper side of the assembly cover 12 via a bearing. The bottom end of the first stirring shaft 13 is connected to the drive end of the stirring motor 10. A second stirring shaft 14 is connected to both sides of the assembly cover 12 via bearings. The second stirring shaft 14 is connected to one end of the first stirring shaft 13 by a bevel gear.

[0025] It should be noted that in the preparation of medical in vitro diagnostic reagents, the raw materials are first put into the cylinder 6 through the feeding port 3. At this time, the two sealing plates 9 located on the lower side of the cylinder 6 are in contact and the lower side of the cylinder 6 is kept sealed, so that the raw materials can stay inside the cylinder 6. The cylinder 6 and the raw materials inside the cylinder 6 are affected by gravity and generate a vertical downward force, which is squeezed by the weighing device 8 through the pressure block 7, so that the raw materials inside the cylinder 6 can be weighed.

[0026] During the weighing process, the cylinder 6 will descend slightly. At this time, the sealing plate 9 will descend with the cylinder 6 inside the opening. One side of the sealing plate 9 is slidably connected to the other side of the moving plate 5 to ensure the stability of the descent of the sealing plate 9. After the raw material inside the cylinder 6 reaches the specified weight, the electric push rod 4 will run and pull the sealing plate 9 horizontally through the moving plate 5, so that the raw material on the top of the sealing plate 9 can fall into the mixing chamber 2. The raw material of medical in vitro diagnostic reagents may be in powder form. After the sealing plate 9 opens, some raw material will stick to the top of the sealing plate 9. At this time, the lower side of the annular block 15 on the top of the sealing plate 9 will scrape off the residual material on the sealing plate 9 and continue to fall into the mixing chamber 2, ultimately achieving the purpose of accurate feeding.

[0027] After the raw materials enter into the mixing bin 2, the stirring motor 10 is operated to drive the first stirring shaft 13 to rotate, since the lower side of the first stirring shaft 13 is connected with the two second stirring shafts 14 through the bevel gears, therefore, when the stirring motor 10 is operated, the first stirring shaft 13 and the second stirring shafts 14 can be simultaneously driven to rotate, and the raw materials in the mixing bin 2 can be efficiently stirred in the horizontal and vertical directions, so as to increase the mixing effect of the raw materials;

[0028] The operator can control the vacuum pump 16 and the heating layer 17 to operate according to the use requirement, the vacuum pump 16 is used for extracting the air in the mixing bin 2, the heating layer 17 is used for satisfying the suitable temperature of the raw material mixing, meanwhile, the mixing bin 2 is provided with the feeding pipe with the one-way valve on one side, which is used for sending the liquid raw material into the mixing bin 2, meanwhile, the mixing bin 2 is provided with the exhaust port with the one-way valve inside on one side, which is used for preventing the pressure in the mixing bin 2 from being too high.

[0029] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the spirit and scope of the present application, the scope of the present application is defined by the appended claims and their equivalents.
