[0002] Reagents, also known as biochemical reagents or test reagents, are pure chemicals used to achieve chemical reactions, analytical tests, research experiments, teaching experiments, and chemical formulations. Medical testing reagent dispensing devices are equipment used to precisely control the dispensing of liquid reagents and are widely used in clinical laboratories, research institutions, and various occasions requiring chemical or biological analysis.

[0003] However, existing medical testing reagent dispensing devices typically use storage bottles for reagent dispensing. These devices lack effective storage bottle positioning structures. Specifically, the storage bottle is not effectively fixed or stabilized during the dispensing process, leading to shaking or tilting. This shaking or tilting directly affects the reagent dispensing process, causing uneven or unstable dispensing, further resulting in errors in the dispensing volume. Because the storage bottle is not properly positioned, the precision of reagent dispensing control cannot be guaranteed, potentially leading to inaccurate reagent usage or failure to meet experimental requirements, ultimately affecting the reagent dispensing effect and the reliability of experimental results.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1, please refer to Figures 1 to 5This utility model provides a technical solution: a reagent dripping device for medical testing, including a device body 1. A storage bottle 101 is disposed inside the device body 1. Slide grooves 102 are formed on both sides of the device body 1. Sliding sliders 103 are slidably connected to the inner surfaces of the two slide grooves 102. Two telescopic columns 104 are fixedly installed on opposite sides of the two sliding sliders 103. Two first return springs 105 are fixedly installed on opposite sides of the two sliding sliders 103. The four telescopic columns 104 and the four first return springs 105 are divided into two groups of two. Clamping plates 106 are fixedly installed at the other ends of the two groups of telescopic columns 104 and the two groups of first return springs 105. Soft pads 107 are provided on the inner sides of the two clamping plates 106. First support columns 108 are fixedly installed on the opposite sides of the two sliding sliders 103. The outer surfaces of the two first support columns 108 are movably fitted with... There are two second support columns 109, both of which are fixedly installed at the bottom of the device body 1. Two second return springs 110 are fixedly installed on opposite sides of the two first support columns 108. The other ends of the two second return springs 110 are fixedly installed inside the second support columns 109. Air pipes 111 are fixedly installed inside the two second support columns 109. Air cylinders 112 are fixedly installed at the other ends of the two air pipes 111. The two air cylinders 112 are fixedly installed on the front side of the device body 1. Movable plates 114 are movably embedded inside the two air cylinders 112. Connecting columns 113 are fixedly installed on the top of the two movable plates 114. A gantry frame 115 is fixedly installed on the top of the device body 1. Electric telescopic rods 116 are fixedly installed on both sides of the top of the gantry frame 115. Connecting plates 117 are fixedly installed at the bottom of the two electric telescopic rods 116.

[0032] In this embodiment, the operator can first place the storage bottle 101 in the device body 1. Then, through the power supply system of the electric telescopic rod 116 on the gantry 115, the electric telescopic rod 116 is activated, so that when it extends, it can push the connecting plate 117 to slide downward inside the gantry 115. The connecting plate 117 presses down the connecting column 113, thereby allowing the movable plate 114 to slide downward inside the air cylinder 112. When the movable plate 114 slides, it will compress the air inside the air cylinder 112, which will be injected into the second support column 109 through the air pipe 111. When the air enters the second support column 109, it will push the first support column 108 to slide outward inside the second support column 109 through air pressure, and pull the second return spring 110 to extend. When the second support column 109 slides, it will push the slider 103 to pass through the slide groove 102. The slide is made by the slider 103, which drives the clamping plate 106 synchronously through the telescopic column 104 and the first return spring 105. This allows the soft pad 107 to fit against the outer surface of the storage bottle 101. When the soft pad 107 fits against the storage bottle 101, the clamping plate 106 squeezes the telescopic column 104 and the first return spring 105, causing them to contract and position the storage bottle 101. The structure of the air cylinder 112 and the clamping plate 106 not only positions the storage bottle 101 to accurately fix it in the predetermined position, but also ensures that the storage bottle 101 remains stable during the dripping process, preventing the storage bottle 101 from shaking or tilting. This makes the reagent dripping more uniform and accurate. At the same time, using the soft pad 107 to fix the storage bottle 101 can effectively prevent the rigid clamp from directly contacting the bottle body, reducing potential damage or friction to the storage bottle 101.

[0033] Example 2, as Figures 1 to 5 As shown, the connecting plate 117 is movably embedded inside the gantry frame 115. The tops of the two connecting columns 113 are fixedly installed on both sides of the bottom of the connecting plate 117. A liquid storage tank 2 is fixedly installed on the top of the gantry frame 115. An inlet pipe 201 is fixedly installed on the top of the liquid storage tank 2. A pump 202 is fixedly installed on the right side of the liquid storage tank 2. An outlet pipe 203 is fixedly installed on the right side of the pump 202. The outer surface of the outlet pipe 203 is movably embedded inside the top side of the gantry frame 115. A nozzle 204 is fixedly installed at the other end of the outlet pipe 203. The nozzle 204 is fixedly embedded inside the connecting plate 117. A sealing gasket 205 is provided on the outer surface of the nozzle 204. The top of the sealing gasket 205 is located at the bottom of the connecting plate 117.

[0034] In this embodiment, when the connecting plate 117 descends, it synchronously drives the nozzle 204 to descend as well, so that the nozzle 204 can be embedded inside the storage bottle 101, and the bottom of the sealing gasket 205 can fit against the top of the storage bottle 101. After the nozzle 204 is embedded inside the storage bottle 101, personnel can inject reagent into the storage tank 2 through the inlet pipe 201, and start the pump 202 through the power supply system of the pump 202, so that when it is running, it can draw out the reagent inside the storage tank 2 and inject it into the nozzle 204 through the outlet pipe 203, thereby... The reagent is dripped into the storage bottle 101 through the nozzle 204. The structure of the nozzle 204 and the sealing gasket 205 not only ensures that the sealing gasket 205 fits tightly against the top of the storage bottle 101 to prevent leakage or reagent spillage and ensure the accuracy of the dripping process, but also, through the coordinated work of the inlet pipe 201 and the pump 202, the reagent is automatically drawn from the storage tank 2 and transported to the nozzle 204 through the outlet pipe 203 for further injection into the storage bottle 101. This automated process reduces the complexity of manual operation, improves efficiency, and ensures the accuracy and consistency of each reagent injection.

[0035] Working principle: In use, the operator first places the storage bottle 101 into the device body 1, and then activates the electric telescopic rod 116 via the power supply system on the gantry 115. During extension, the electric telescopic rod 116 pushes the connecting plate 117 downwards inside the gantry 115, pressing down the connecting column 113. This causes the movable plate 114 to slide downwards inside the air cylinder 112. As the movable plate 114 slides, it compresses the air inside the air cylinder 112, injecting it into the second support column 109 through the air pipe 111. Once the air enters the second support column 109, it pushes the first support column 108 outwards inside the second support column 109, pulling the second return spring 110 for extension. As the second support column 109 slides, it pushes the slider 103, causing it to pass through the groove 1. 02 slides, and the slider 103 drives the clamping plate 106 synchronously through the telescopic column 104 and the first return spring 105, so that the soft pad 107 can fit against the outer surface of the storage bottle 101. When the soft pad 107 fits against the storage bottle 101, the clamping plate 106 will squeeze the telescopic column 104 and the first return spring 105, causing them to contract, so as to position the storage bottle 101. Through the structure of the air cylinder 112 and the clamping plate 106, the storage bottle 101 can not only be positioned to accurately fix the storage bottle 101 in the predetermined position, but also ensure that the storage bottle 101 remains stable during the dripping process, avoiding shaking or tilting of the storage bottle 101, so as to make the reagent dripping more uniform and accurate. At the same time, using the soft pad 107 to fix the storage bottle 101 can effectively avoid the hard clamp directly contacting the bottle body, reducing potential damage or friction to the storage bottle 101. In use, when the connecting plate 117 descends, it synchronously drives the nozzle 204 to descend as well, allowing the nozzle 204 to embed itself inside the storage bottle 101. This ensures that the bottom of the sealing gasket 205 fits snugly against the top of the storage bottle 101. After the nozzle 204 is embedded in the storage bottle 101, personnel can inject reagent into the storage tank 2 through the inlet pipe 201. The pump 202 is then activated via its power supply system, allowing it to extract the reagent from the storage tank 2 and inject it into the nozzle 204 through the outlet pipe 203. The nozzle 204 drips the reagent into the storage bottle 101. The structure of the nozzle 204 and the sealing gasket 205 ensures that the sealing gasket 205 fits tightly against the top of the storage bottle 101, preventing leakage or reagent spillage and ensuring the accuracy of the dripping process. At the same time, through the coordinated work of the inlet pipe 201 and the pump 202, the reagent is automatically drawn from the storage tank 2 and transported through the outlet pipe 203 to the nozzle 204 for further injection into the storage bottle 101. This automated process reduces the complexity of manual operation, improves efficiency, and ensures the accuracy and consistency of each reagent injection.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
