DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model.

[0023] The utility model provides technical scheme: such as Figures 1-2 、 Figures 4-5As shown in the embodiment, the reagent classification device for radiopharmaceutical toxicology experiment includes a reagent placing box 100 and a clamping fixing assembly 200. A fixed plate 109 and an elastic plastic placing plate 108 are placed in the reagent placing box 100. The fixed plate 109 is screwed in the inside of the reagent placing box 100. The elastic plastic placing plate 108 is fixed in the inside of the reagent placing box 100 by colloid. The elastic plastic placing plate 108 is made of elastic plastic material. Small holes are arranged in the inside of the elastic plastic placing plate 108. Reagent tubes 107 are placed in the small holes of the elastic plastic placing plate 108. Different sizes of reagent tubes 107 are inserted through the small holes in the inside of the elastic plastic placing plate 108. The small holes of the elastic plastic placing plate 108 are expanded. When the test tubes are placed in the small holes, the inside of the elastic plastic placing plate 108 is contracted and tightened. The outside of the reagent tubes 107 is in contact with first clamping plates 203 and second clamping plates 204. Rubber pads are arranged on the outside of the first clamping plates 203 and the second clamping plates 204. The rubber pads are in contact with the outside of the reagent tubes 107. One end of the first clamping plates 203 and the second clamping plates 204 is connected and fixed with a telescopic rod 207 through a bolt. One end of the telescopic rod 207 is connected and fixed with a compression spring 206 through a screw. One end of the compression spring 206 is connected in the inside of a telescopic cylinder 205 through a screw. The telescopic cylinder 205 is connected in the through hole in the inside of a clamping mounting block 201 through a bolt. A sliding groove 202 is arranged in the upper end of the clamping mounting block 201. The lower end of the clamping mounting block 201 is connected with the upper end of the fixed plate 109 through a bolt. A sliding block 208 is slidably connected in the inside of the sliding groove 202. The sliding block 208 can move in the sliding groove 202. A handle 209 is fixedly installed on the upper end of the sliding block 208. In actual use, first, different sizes of reagent tubes 107 are inserted through the small holes in the inside of the elastic plastic placing plate 108. The small holes of the elastic plastic placing plate 108 are expanded. When the test tubes are placed in the small holes, the inside of the elastic plastic placing plate 108 is contracted and tightened. Then, the handle 209 is moved by the operator to drive the sliding block 208 to move in the sliding groove 202, thereby driving the telescopic rod 207 to move in the telescopic cylinder 205. The compression spring 206 is compressed. When the reagent tubes 107 are clamped and fixed, the operator only needs to support and slowly move the handle 209. The telescopic rod 207 is driven to move outward in the telescopic cylinder 205 by the elastic force and extrusion of the compression spring 206, thereby further driving the first clamping plates 203 and the second clamping plates 204 to move and clamp the reagent tubes 107. Different sizes of reagent tubes 107 can be effectively placed and clamped and fixed.

[0024] Through the elastic plastic placement plate 108 and the clamping and fixing assembly 200, the small hole of the elastic plastic placement plate 108 can be expanded, effectively adapting to different sizes of reagent tubes 107, so that the device can fix reagent tubes of various specifications. Through the elastic force and extrusion effect of the compression spring 206, the first clamping plate 203 and the second clamping plate 204 can tightly contact and clamp the reagent tube 107, avoiding experimental errors or accidents caused by shaking of the test tube. The reagent tube placement box can effectively place and clamp and fix different sizes of reagent tubes 107.

[0025] As shown in Figures 1-3 The outer side of the reagent tube 107 is sleeved with a isolation sleeve 110, which is inserted into the inside of the elastic plastic placement plate 108. The upper end of the reagent placement box 100 is provided with a moving groove 104 on both sides, and the inside of the moving groove 104 is slidably connected with a moving rod 103. The upper end of the moving rod 103 is connected and fixed with the shielding cover plate 101 through a bolt. The upper end of the shielding cover plate 101 is provided with a handle 102. In actual use, the operator inserts the radioactive drug reagent tube 107 into the corresponding isolation sleeve 110, and then inserts the isolation sleeve 110 into the inside of the elastic plastic placement plate 108. Then, the moving rod 103 is slid in the moving groove 104, which drives the shielding cover plate 101 to move, so as to cover and close the reagent placement box 100. The materials of the isolation sleeve 110 and the shielding cover plate 101 are usually lead, tungsten alloy or other high-density materials. These materials are widely used in the storage and transportation of radioactive substances due to their excellent radiation shielding performance. Lead is a commonly used radiation shielding material because it has good absorption capacity for gamma rays and X-rays. Tungsten alloy has high density and excellent mechanical properties, and performs well in applications that require higher strength and smaller size.

[0026] Through the isolation sleeve 110 and the shielding cover plate 101, the influence of the radiation released by the drug in the reagent tube 107 on the surrounding environment and personnel can be effectively reduced. The isolation sleeve 110 and the shielding cover plate 101 provide an additional physical protection layer for the radioactive drug reagent tube 107, preventing accidental breakage or leakage of the test tube, thereby avoiding the diffusion of radioactive substances.

[0027] The utility model provides a reagent classification device for radioactive treatment drug toxicology experiment, specific working principle is as follows: reagent classification device for radioactive treatment drug toxicology experiment mainly classifies based on the characteristic of radioactive nuclide and the mechanism of action of drug. Different radioactive nuclide has different decay type (such as alpha, beta, gamma ray or auger electron), and these characteristics determine their biological effect and penetration ability in vivo. The device classifies reagents into different categories by recognizing these characteristics, and the operator inserts the radioactive reagent tube 107 into the appropriate isolation sleeve 110, then places the isolation sleeve 110 inside the elastic plastic placement plate 108, then inserts the reagent tube 107 of different sizes through the small hole in the elastic plastic placement plate 108, the small hole in the elastic plastic placement plate 108 expands, and when the test tube is placed in the small hole, the inside of the elastic plastic placement plate 108 contracts, then the operator moves the handle 209, drives the sliding block 208 to move inside the sliding groove 202, and further drives the telescopic rod 207 to move inside the telescopic cylinder 205, the compression spring 206 is compressed, when clamping and fixing the reagent tube 107, the operator only needs to hold the handle 209 and move slowly, the elastic force of the compression spring 206 and the extrusion effect drive the telescopic rod 207 to move outward inside the telescopic cylinder 205, further drive the first clamping plate 203 and the second clamping plate 204 to move and contact and clamp the reagent tube 107, which can effectively place and clamp and fix the reagent tube 107 of different sizes.

[0028] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
