However, when using this type of mixing device, various drug stock solutions need to be added through the device's liquid addition tube. During this process, the stock solution will remain on the inner wall of the liquid addition tube, resulting in inaccurate drug preparation quantity.

[0003] A Chinese patent with the publication number "CN214051254U" discloses a liquid medicine dispensing device for a hospital pharmacy. By setting up a liquid adding hopper, an extension block, an extrusion spring, a rebound limiting block and a rubber pad, the bottom end of the liquid adding hopper is inserted into the insertion gap between the two sets of rubber pads. This can stabilize the liquid adding hopper, effectively avoid drug residue in the liquid adding tube, and make the amount of drug dispensed more accurate.

[0004] During the stirring and mixing process of the above-mentioned liquid medicine preparation device, the stirring structure cannot completely and comprehensively cover the inner bottom of the preparation box, which easily leads to the formation of stirring dead corners, so that the medicine cannot be fully stirred, and thus causes uneven stirring. In addition, the stirring structure lacks the function of transporting the medicine up and down. During the stirring process, when the medicine is located inside the preparation box, the medicine at the bottom cannot be quickly and evenly mixed with the medicine at the top, making it impossible to achieve uniform and efficient mixing during the overall stirring and mixing period, and the performance in terms of mixing performance and uniformity is poor.

The lifting mechanism 3 on the upper end of the back of the preparation tank 5 cooperates with the sealing cover 4 on the front side to facilitate the installation and maintenance of the stirring mechanism 6. When cleaning is required, the stirring mechanism 6 can be easily pulled out of the preparation tank 5, thereby improving the maintainability of the device.

[0026] The stirring mechanism 6 includes a first motor 61, which is fixedly connected to the middle of the top of the sealing cover 4. The output end of the first motor 61 passes through the sealing cover 4 and is fixedly installed with a rotating shaft 62. The rotating shaft 62 is vertically arranged. The upper end of the outer surface of the rotating shaft 62 is fixedly installed with a stirring side frame 63. The lower end of the outer surface of the rotating shaft 62 is fixedly connected with a stirring auger 64. The first motor 61 in the stirring mechanism 6 can provide powerful power for stirring. The first motor 61 drives the rotating shaft 62 to rotate. The stirring side frame 63 on the upper end of the outer surface of the rotating shaft 62 can stir the mixture in the preparation tank 5. The medicine at the upper end is efficiently stirred and mixed, and the stirring auger 64 at the lower end of the outer surface of the rotating shaft 62, on the one hand, can perfectly fit with the bottom of the preparation tank 5 due to its special shape, and can assist in rolling the medicine liquid upward during the stirring process, so that the medicine liquid is stirred and mixed up and down at all times, which greatly improves the stirring efficiency and uniformity. In addition, the discharge valve 7 at the bottom of the preparation tank 5 facilitates the discharge of the prepared medicine liquid, and the internal electric heating coil 8 can heat the medicine as needed to meet the preparation requirements of different medicines, providing reliable guarantee for the uniform mixing and preparation of the medicine.

[0027] Specific as Figure 2-Figure 4 As shown, the stirring auger 64 is set in an inverted cone shape, the preparation tank 5 is set in an inverted cone shape, the top side of the sealing cover 4 is fixedly connected with a regulating valve 9, the top of the regulating valve 9 is fixedly connected with a guide bucket 10, and the bottom of the regulating valve 9 passes through the sealing cover 4. The stirring auger 64 is in an inverted cone shape, which perfectly matches the overall inverted cone shape of the preparation tank 5, so that the stirring auger 64 can fit the inner wall of the preparation tank 5 to the greatest extent during the rotation process, thereby more effectively stirring the medicine in the tank. The conical design can also promote During the stirring process, the medicine naturally gathers toward the center, which improves the uniformity and efficiency of stirring. The regulating valve 9 on the top side of the sealing cover 4 can accurately control the amount and speed of medicine addition. The guide bucket 10 on the top of the regulating valve 9 can easily guide the medicine into the regulating valve 9, ensuring that the medicine flows accurately into the preparation tank 5. The bottom of the regulating valve 9 passes through the sealing cover 4, making the medicine addition process smoother and more controllable. This design not only improves the accuracy of medicine preparation, but also facilitates operation, providing a strong guarantee for the uniform mixing and preparation of medicines.

[0028] like Figure 1-Figure 3As shown, the lifting mechanism 3 includes a vertical rail 31, which is fixedly mounted on the top of the support frame 2 located in the middle of the rear side, and a second motor 32 is fixedly connected to the bottom of the vertical rail 31. The output end of the second motor 32 passes through the vertical rail 31 and is fixedly connected to a screw rod 33. The outer surface of the screw rod 33 is threadedly connected to a slider 34. The slider 34 is slidably connected to the inner side of the vertical rail 31. The front side of the slider 34 is fixedly connected to a connecting frame 35. The front end of the connecting frame 35 is fitly connected to the top of the sealing cover 4. The vertical rail 31 is fixedly mounted on the top of the support frame 2 located in the middle of the rear side, providing a stable support structure for the entire lifting mechanism 3. The second motor 32 at the bottom of the vertical rail 31 serves as a power source and can accurately drive the screw rod 33 to rotate. The screw rod 33 and the slider 3 The threaded connection design of 4 enables the rotational motion of the motor to be converted into the linear motion of the slider 34. The slider 34 is slidably connected to the inner side of the vertical rail 31, ensuring the stability and directionality of the slider 34 during the up and down movement. When the stirring mechanism 6 needs to be maintained or cleaned, the second motor 32 is started, and the screw rod 33 drives the slider 34 to move upward in the vertical rail 31. The connecting frame 35 on the front of the slider 34 rises accordingly, and the front end of the connecting frame 35 is fitted and connected with the top of the sealing cover 4, so that the sealing cover 4 and the stirring mechanism 6 can be smoothly pulled out of the preparation tank 5, which greatly improves the maintainability and operational convenience of the device, reduces the difficulty and workload of manual operation, and provides a strong guarantee for the long-term stable operation of the drug preparation device.

[0029] like Figure 2-Figure 4As shown, the top view shape of the slider 34 and the overall cross-sectional shape inside the vertical rail 31 are both set as convex shapes, making the sliding of the slider 34 in the vertical rail 31 more stable, not prone to deviation or shaking, ensuring the reliability of the operation of the lifting mechanism 3. A wear-resistant gasket is fixedly connected to the outer surface of the slider 34, which can reduce the friction between the slider 34 and the vertical rail 31, reduce the wear degree, and extend the service life of the slider 34 and the vertical rail 31. A sealing washer is fixedly connected to the bottom of the sealing cover 4, enhancing the sealing performance, preventing the leakage of drugs during the stirring process, and ensuring the safety and accuracy of the preparation process. A number of stirring rods 65 are fixedly connected at equal intervals on the inner side of the stirring side frame 63. The outer shape of the stirring side frame 63 is set as a shape like a reverse slash that is inclined towards the rotating shaft 62. Installation holes 11 are opened at the four corners of the top of the base frame 1, and the installation holes 11 are all set as countersunk holes. The outer edges of the base frame 1 and the support frame 2 are all set as arc-shaped. The stirring rods 65 at equal intervals on the inner side of the stirring side frame 63 can further improve the stirring effect and make the drug mixture more uniform. The outer side of the stirring side frame 63 is set as a shape like a reverse slash that is inclined towards the inside, which can better guide the flow of drugs during the stirring process and improve the stirring efficiency. The installation holes 11 at the four corners of the top of the base frame 1 are set as countersunk holes, making the installation of the device more beautiful and tidy, and at the same time enhancing the installation stability. The outer edges of the base frame 1 and the support frame 2 are set as arc-shaped, which is not only softer and more beautiful in appearance, but also can effectively reduce the risk of personnel being injured due to accidental collisions during the operation process.

[0030] The specific working principle is as follows: First, it is guided by the guiding hopper 10, so that the drug is added into the regulating valve 9. After the regulating valve 9 is opened, the drug can be smoothly transported into the preparation tank 5. When the drug addition is completed, the first motor 61 is started to operate. The first motor 61 can drive the rotating shaft 62 to rotate. When the rotating shaft 62 rotates, it will带动 the stirring side frame 63, the stirring auger 64 and the stirring rods 65 to rotate together. The drugs at the upper end in the preparation tank 5 can be efficiently stirred and mixed. During the stirring process, the drugs will flow downward. At this time, the inverted conical stirring auger 64 fits perfectly with the bottom of the preparation tank 5. As the rotating shaft 62 drives the stirring auger 64 to rotate, it can assist in driving the liquid medicine to roll upward. During the period when the liquid medicine rolls upward, it can be stirred again through the stirring side frame 63 and the stirring rods 65. During the stirring process, the liquid medicine can always be in a state of being stirred up and down, prompting the liquid medicine to roll up and down efficiently and evenly. While the stirring efficiency is higher, the stirring uniformity is also stronger. And after the stirring and mixing are completed, only by opening the discharge valve 7 at the bottom can the prepared liquid medicine be discharged.

[0031] When cleaning is required, start the driving motor to drive the screw rod 33 to drive the slider 34 to move upward, and then the connecting frame 35 can be pulled out and moved upward from the sealing cover 4 to open the preparation tank 5, and at the same time the stirring mechanism 6 can also be taken out. The overall cleaning and maintenance are relatively convenient and easy to use.
