Description

Technical Field

[0001] This utility model belongs to the field of medical research, specifically relating to an automated device for mixing medicines for medical research. Background Technology

[0002] In the field of medical research, drug mixing is a crucial step in drug development, formulation optimization, and pharmacological experiments. It places extremely high demands on mixing accuracy, efficiency, and safety. As a core piece of equipment, the drug mixing device provides a stable mixing system for experiments by quantitatively proportioning, uniformly stirring, and controlling the reaction environment of various drug raw materials. This directly affects the accuracy of research data and the reliability of experimental results, making it an important tool for promoting the efficient conduct of medical research.

[0003] Currently, related drug mixing devices lack readily replaceable metering drug storage bottles, making it difficult to quickly replace and accurately add various raw materials, and the operation is cumbersome when changing drugs; in addition, there is a lack of effective control mechanisms for the high-pressure gas generated by chemical reactions during the mixing process, which poses safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide an automated drug mixing device for medical research, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automated drug mixing device for medical research includes a medicine bottle, a mixing tank, and a temperature sensor. A motor is fixedly connected to the top of the mixing tank, and a mixing shaft is fixedly connected to the bottom of the motor inside the mixing tank. Metering valves are fixedly connected to the top of the mixing tank on both sides of the motor. Limiting blocks are fixedly connected to the top of the mixing tank on both sides of the metering valves. A manual butterfly valve is movably installed on the top of the metering valve, and a medicine bottle is fixedly connected to the top of the manual butterfly valve. A pressure limiting valve is fixedly connected to the top of the mixing tank at one end of the motor, and a gas collecting tank is fixedly connected to one end of the mixing tank. A gas guide pipe is provided on the top of the gas collecting tank surrounding the pressure limiting valve, and a sealing butterfly valve is fixedly connected to one end of the gas collecting tank.

[0007] Preferably, support blocks are fixedly connected to both sides of the bottom of the medicine bottle, and the support blocks are fitted into the limiting blocks.

[0008] Preferably, a sealing ring is fixedly connected to the bottom of the manual butterfly valve, and the sealing ring is fitted with the metering valve.

[0009] Preferably, a threaded tube is fixedly connected to the top of the medicine bottle, and a sealing cap is movably installed on the top of the threaded tube.

[0010] Preferably, one end of the sealing butterfly valve is fixedly connected to a flange, and the flange has a bolt hole inside.

[0011] Preferably, a fixing frame is fixedly connected to one end of the mixing tank surrounding the gas collecting tank, and the fixing frame is made of stainless steel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes a quick-detachable combination structure of medicine bottle and metering valve, along with a sealing ring design, to achieve precise metering and rapid replacement of various drug ingredients. Operators can flexibly adjust the metering valve according to the mixing ratio, controlling the timing and amount of material added. Furthermore, the interlocking positioning of the support block and limit block significantly simplifies the medicine bottle replacement process, improving the efficiency and convenience of drug mixing and preparation. Simultaneously, the motor-driven mixing shaft ensures uniform mixing of the ingredients, meeting the mixing precision requirements of medical research.

[0014] This invention effectively ensures the safety of the device operation by combining the synergistic effect of the pressure relief valve and the gas collection tank with the real-time monitoring function of the temperature sensor. When high pressure is generated during the mixing process, the pressure relief valve automatically opens and guides the gas into the gas collection tank for temporary storage through the gas guide pipe, avoiding the risk of leakage caused by high pressure. The temperature sensor monitors the temperature inside the mixing tank in real time, making it easy to control the reaction status in a timely manner, while the sealing butterfly valve enables the safe discharge of gas, further improving the stability and reliability of operation.

Detailed Implementation

[0021] 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.

[0022] 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.

[0023] 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.

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] Example 1: This example provides an automated drug mixing device for medical research, including a medicine bottle 1, a mixing tank 6, and a temperature sensor 7. A motor 5 is fixedly connected to the top of the mixing tank 6. A mixing shaft 501 is fixedly connected to the bottom of the motor 5 inside the mixing tank 6. Metering valves 2 are fixedly connected to the top of the mixing tank 6 on both sides of the motor 5. Limiting blocks 3 are fixedly connected to the top of the mixing tank 6 on both sides of the metering valves 2. A manual butterfly valve 103 is movably installed on the top of the metering valve 2. The medicine bottle 1 is fixedly connected to the top of the manual butterfly valve 103. A pressure limiting valve 8 is fixedly connected to the top of the mixing tank 6 at one end of the motor 5. A gas collecting tank 11 is fixedly connected to one end of the mixing tank 6. A gas guide pipe 4 is provided on the top of the gas collecting tank 11 around the pressure limiting valve 8. A sealing butterfly valve 9 is fixedly connected to one end of the gas collecting tank 11. Support blocks 104 are fixedly connected to both sides of the bottom of the medicine bottle 1, and the support blocks 104 are fitted with the limiting blocks 3. A sealing ring 105 is fixedly connected to the bottom of the manual butterfly valve 103, and the sealing ring 105 is fitted with the metering valve 2.

[0026] The staff first stores the raw materials to be mixed into multiple medicine bottles 1. The support block 104 at the bottom of the medicine bottle 1 is engaged with the limiting block 3 at the top of the mixing tank 6 to fix the medicine bottle 1 above the metering valve 2. At the same time, the sealing ring 105 at the bottom of the manual butterfly valve 103 is engaged with the metering valve 2 to achieve a seal. According to the preset mixing ratio, the valve stem of the metering valve 2 is turned to adjust the amount of raw materials added. The manual butterfly valve 103 is opened to allow the raw materials to enter the mixing tank 6. If the raw materials need to be replaced, the medicine bottle 1 is pulled upward to separate the support block 104 from the limiting block 3, so that the medicine bottle 1 containing other raw materials can be quickly disassembled and replaced. The operation is convenient. After the raw materials enter the mixing tank 6, the motor 5 is connected to an external power source. The motor 5 drives the mixing shaft 501 inside the mixing tank 6 to rotate, so as to uniformly stir and mix the various raw materials.

[0027] When the drug reaction generates high pressure during the mixing process, the pressure relief valve 8 at the top of the mixing tank 6 automatically opens to release the pressure, guiding the high-pressure gas inside through the gas guide pipe 4 into the gas collection tank 11 for temporary storage. This prevents leakage or damage to the device due to excessive pressure and improves operational safety. At the same time, the detection probe of the temperature sensor 7 extends into the mixing tank 6 to monitor the temperature changes during the mixing process in real time. After the mixing is completed, the operator can turn and open the sealing butterfly valve 9 to safely discharge the gas in the gas collection tank 11, ensuring stable operation of the device.

[0028] Example 2: This example is basically the same as the previous example, except that a threaded tube 101 is fixedly connected to the top of the medicine bottle 1, and a sealing cap 102 is movably installed on the top of the threaded tube 101.

[0029] Staff members feed the raw materials for medical research drugs into the medicine bottle 1 through the threaded tube 101, and the sealing cap 102 can seal the threaded tube 101.

[0030] Specifically, one end of the sealing butterfly valve 9 is fixedly connected to a flange 901, and the flange 901 has a bolt hole inside.

[0031] The operator connects the external gas outlet pipe to flange 901, then screws the external fixing bolts between the gas outlet pipe and flange 901 and through the bolt holes, thus connecting the external gas outlet pipe to the sealing butterfly valve 9 and performing the venting operation.

[0032] Specifically, a fixing frame 10 is fixedly connected to one end of the mixing tank 6 surrounding the gas collecting tank 11, and the fixing frame 10 is made of stainless steel.

[0033] The fixing frame 10 increases the contact area and friction between the gas collecting tank 11 and the mixing tank 6, thereby improving the stability of the gas collecting tank 11 installation.
