Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical testing technology, specifically relating to a spray device for a colorimetric reagent in pharmaceutical testing. Background Technology

[0002] Chromogenic reagents for pharmaceutical testing are chemical reagents that react with specific components to produce a colorimetric reaction during drug analysis and detection. Their working principle involves a specific chemical reaction with the active ingredient, impurities, or specific functional groups in the drug, producing a noticeable color change (such as discoloration, color development, or fluorescence), thereby enabling qualitative or semi-quantitative analysis of the drug. These reagents must possess characteristics such as high reaction sensitivity, stable color development, and strong specificity. They are widely used in detection methods such as thin-layer chromatography and high-performance liquid chromatography, and are important tools for drug quality control and component identification.

[0003] In the process of drug testing, it is usually necessary to use a spray device to spray colorimetric reagents for testing. However, since different drugs require different colorimetric reagents, and traditional spray devices are cumbersome and time-consuming to change colorimetric reagents, this directly affects the overall efficiency of drug testing.

Detailed Implementation

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0026] Reference Figure 1-5 This embodiment of the present invention provides a spray device for a colorimetric reagent in pharmaceutical testing, comprising:

[0027] The spraying mechanism 100 includes a support platform 110, an output pump 120 and a vertical plate 130 respectively fixedly installed on the top of the support platform 110, a feed pipe 140 connected to the input end of the output pump 120, a plurality of storage bottles 150 for holding colorimetric reagents, a side frame 160 fixedly installed on the top of the support platform 110 for placing thin-layer chromatography plates, and an atomizing nozzle provided at the output end of the output pump 120 for spraying the colorimetric reagents.

[0028] The replacement mechanism 200 includes a switching component 210 for easy switching between different storage bottles 150, and a limiting component 220 for assisting in positioning the switching component 210.

[0029] The switching component 210 and the limiting component 220 work together to quickly switch the corresponding colorimetric reagent for different drugs to be tested. This solves the problem of low detection efficiency caused by the cumbersome process of changing the colorimetric reagent when traditional spray devices detect different drugs, improves the speed of colorimetric reagent changing, and achieves efficient detection of different types of drugs.

[0030] Specifically, the switching component 210 includes a turntable 211 rotatably mounted on the top of the support platform 110 via a rotating shaft, and several fixing sleeves 212 fixedly mounted on the top of the turntable 211 and used to limit the storage bottle 150. The bottom of the storage bottle 150 is engaged inside the fixing sleeve 212.

[0031] Furthermore, a number of support blocks 213 supporting the turntable 211 are fixedly installed on the top of the support platform 110. A ball bearing 214 is movably installed on the top of the support block 213. The ball bearing 214 contacts the bottom of the turntable 211. A number of jerky grooves 215 are opened on the arc surface of the turntable 211.

[0032] The number of jolt grooves 215 is the same as the number of fixed sleeves 212. Through the cooperation between the support block 213 and the ball bearing 214, they are used to support the turntable 211 and prevent the turntable 211 from tilting when rotating, thus affecting the stability of the storage bottle 150.

[0033] Preferably, the limiting component 220 includes a protruding plate 221 fixedly installed on the top of the support platform 110, a spring 222 fixedly installed on one side of the protruding plate 221, and a locking rod 223 fixedly connected to the end face of the spring 222 via a circular plate, the end of the locking rod 223 being engaged inside the jerking groove 215.

[0034] The spring 222 applies elastic pressure to the lever 223, causing the end of the lever 223 to engage with the inside of the jolt groove 215, which limits the turntable 211 and improves the stability of the storage bottles 150 on the turntable 211.

[0035] Furthermore, the end of the lever 223 is arc-shaped, and the surface of the protrusion 221 is provided with a connecting groove for use with the lever 223.

[0036] By setting the end of the lever 223 to be arc-shaped, it is convenient for the end of the lever 223 to engage with or disengage from the inside of the jerking groove 215.

[0037] Specifically, the feed pipe 140 includes a feed pipe 141 connected to the input end of the output pump 120, a cover plate 142 connected to one end of the feed pipe 141, a corrugated pipe 143 connected to the bottom of the cover plate 142, and a suction pipe 144 for sealing the opening of the storage bottle 150.

[0038] The cover plate 142 is used to extend and retract the corrugated tube 143, so that the corrugated tube 143 can extend into the interior of the storage bottle 150 to draw out the color developer, or to move the corrugated tube 143 out of the interior of the storage bottle 150 and seal the opening at the top of the storage bottle 150 under the action of the suction tube 144 to prevent the color developer from spilling out.

[0039] Furthermore, a mounting frame for placing a thin-layer chromatography plate is fixedly installed on the side of the side frame 160 near the atomizing nozzle, and a limiting groove for fixing the thin-layer chromatography plate is provided on the inner side of the mounting frame.

[0040] The mounting frame and the limiting groove are used to fix and limit the thin-layer chromatography plate, so as to prevent the colorimetric agent from being deflected when the atomizing nozzle sprays the colorimetric agent onto the thin-layer chromatography plate, which would cause inaccurate color development.

[0041] When using different color developers, it is necessary to switch the storage bottle 150 to use the color developer inside. Manually rotate the turntable 211. Under the pressure of the arc surface of the turntable 211, the end of the locking rod 223 is disengaged from the inside of the jolt groove 215. Rotate the storage bottle 150 to be used to the bottom of the bellows 143. At this time, under the elastic force of the spring 222, the end of the locking rod 223 is locked into the inside of the corresponding jolt groove 215, which limits the turntable 211.

[0042] Then pull the cover plate 142 down to extend the bellows 143 into the interior of the storage bottle 150 and close the feed pipe 141 at the opening of the storage bottle 150.

[0043] Insert the thin-layer chromatography plate into the fixed frame, start the output pump 120, and pump out the colorimetric reagent inside the storage bottle 150 under the action of the output pump 120, and spray the colorimetric reagent onto the thin-layer chromatography plate through the atomizing nozzle.

[0044] In summary, by coordinating the switching component 210 and the limiting component 220, the corresponding colorimetric reagent can be quickly switched for different drugs to be tested. This solves the problem of low detection efficiency caused by the cumbersome process of changing the colorimetric reagent when traditional spray devices detect different drugs, improves the speed of colorimetric reagent changing, and achieves efficient detection of different types of drugs.
