Technical Field

[0001] This application relates to the technical field of pharmaceutical preparation tanks, and in particular to a pharmaceutical preparation tank with a movable stirring paddle. Background Technology

[0002] Pharmaceutical preparation tanks are used to mix and stir different materials to achieve processes such as chemical reactions, dissolution, or crystallization, as well as heating and cooling. Furthermore, the tanks can be heated or cooled according to production and process requirements to adapt to different material characteristics. Moreover, the pharmaceutical preparation tanks maintain stable material temperatures through heat preservation, which is beneficial for reaction progress or material storage. Therefore, a pharmaceutical preparation tank with a movable stirring paddle is proposed for use.

[0003] The existing Chinese utility model patent with publication number CN206500078U discloses a pharmaceutical preparation tank based on a movable stirring paddle. This pharmaceutical preparation tank includes a tank body, a stirring device mounted on the tank body, a drive motor for rotating the stirring device, and an inlet and outlet on the tank body. The stirring device includes a stirring shaft mounted on the motor shaft of the drive motor via a coupling, a groove along the axial direction of the stirring shaft, a sliding member within the groove and matching its shape, a stirring paddle fixed to the sliding member, a bolt extending from the groove through the sliding member onto the stirring shaft, and a nut at the other end of the bolt for fixing the sliding member to the stirring shaft. This utility model has advantages such as facilitating the mixing of pharmaceutical solutions of different heights.

[0004] The existing movable agitator-driven drug preparation tanks do not allow for separate proportioning of drugs during preparation, which can easily lead to over- or under-addition of drugs, affecting their efficacy. This issue needs improvement. Utility Model Content

[0005] The purpose of this application is to provide a pharmaceutical preparation tank with a movable agitator to improve the accuracy of drug addition.

[0006] The present application provides a movable stirring paddle pharmaceutical preparation tank with the following technical solution: it includes a mixing tank, a stirring mechanism connected inside the mixing tank, and a pharmaceutical preparation mechanism connected to the mixing tank. The pharmaceutical preparation mechanism includes a dispensing pipe connected to the mixing tank, a preparation tank connected to the dispensing pipe, several dispensing pipes connected to the preparation tank, and dispensing bottles connected to each dispensing pipe. The end of the dispensing pipe away from the preparation tank is connected to the mixing tank. Each dispensing pipe is connected to a first control valve for controlling the on / off state of the corresponding dispensing pipe, and the dispensing pipe is connected to a second control valve for controlling the on / off state of the dispensing pipe.

[0007] By employing the above technical solution, different drugs are added to different dispensing bottles. A first control valve opens the corresponding dispensing tube, allowing the drug in the dispensing bottle to flow into the preparation tank. When a certain amount of drug has flowed through the dispensing bottle, the first control valve closes the corresponding dispensing tube, thereby controlling the amount of different drugs added to the preparation tank and improving the accuracy of drug addition. After the different drugs are added to the preparation tank, they are initially mixed. A second control valve then opens the flow pipe, allowing the drug from the preparation tank to be added to the mixing tank for stirring.

[0008] Optionally, the preparation tank is rotatably connected to the flow pipe, and the preparation tank is connected to a first handle.

[0009] By adopting the above technical solution, after the drugs from each bottle are added to the preparation tank, the preparation tank can be rotated by the first handle to ensure that different drugs are dispersed in different areas of the preparation tank, fully mixed, and avoiding local concentrations that are too high or too low.

[0010] Optionally, each of the bottle segments is connected to a vibrating ring for driving the vibration of the corresponding bottle segment.

[0011] By adopting the above technical solution, the vibrating ring drives the corresponding bottle to vibrate, so that the drugs inside the bottle are initially mixed.

[0012] Optionally, the stirring mechanism includes a rotating rod rotatably connected inside the ingredient barrel and a driving component for driving the rotating rod to rotate. The driving component is connected to the ingredient barrel, and the rotating rod is connected to a plurality of stirring fans.

[0013] By adopting the above technical solution, the driving component drives the rotating rod to rotate, that is, the stirring fan rotates. During the rotation of the stirring fan, the medicine in the mixing tank is mixed to avoid local concentrations being too high or too low.

[0014] Optionally, the stirring mechanism further includes a bending rod, and the driving member is used to drive the bending rod to rotate. One end of the bending rod is connected to the output end of the driving member, and the other end is connected to the rotating rod. The axis of the rotating rod is located at the eccentricity of the output end of the driving member.

[0015] By adopting the above technical solution, the driving component drives the bent rod to rotate, that is, both the rotating rod and the stirring fan rotate around the axis of the output end of the driving component, which increases the rotation range of the stirring fan in the mixing tank, that is, increases the contact area between the stirring fan and the drug, and improves the stirring effect of the drug.

[0016] Optionally, the rotating rod is connected to a plurality of connecting rods, and each of the connecting rods is connected to a stirring rod.

[0017] By adopting the above technical solution, when the rotating rod rotates, several connecting rods rotate along with the rotating rod, increasing the contact area with the material and improving the stirring effect of the drug.

[0018] Optionally, the connecting rod and the stirring rod are inclined relative to the axis of the rotating rod.

[0019] By adopting the above technical solution, the inclined connecting rod and stirring rod can drive the medicine in the mixing tank to move in different directions during rotation, increasing the area on which the medicine moves in the mixing tank and improving the stirring effect of the medicine.

[0020] Optionally, each of the stirring rods is movably connected to a telescopic rod, and a movable rod is connected to the end of the telescopic rod away from the stirring rod.

[0021] By adopting the above technical solution, the telescopic rod and the interactive rod extend to a certain length according to the rotation speed of the rotating rod. The extended movable rod can mix the medicine in the mixing tank at different positions, increasing the contact area with the medicine and improving the stirring effect of the medicine.

[0022] Optionally, it also includes a base, the mixing barrel is connected to a rotating column, the base is provided with a rotating groove for rotating with the rotating column, and the mixing barrel is connected to a second handle.

[0023] By adopting the above technical solution, the mixing effect of the medicine in the mixing tank is improved by rotating the mixing tank with the second handle. During the rotation of the mixing tank, the rotating column rotates within the rotating groove. The rotation of the rotating column and the rotating groove cooperate to guide and limit the rotation of the mixing tank, thereby improving the stability of the mixing tank's rotation.

[0024] Optionally, the ingredient container is connected to an observation mirror.

[0025] By adopting the above technical solution, the condition inside the ingredient tank can be observed through an observation mirror.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Different drugs are added to different dispensing bottles. The first control valve opens the corresponding dispensing tube, allowing the drug in the bottle to flow into the preparation tank. When a certain amount of drug has flowed through the dispensing bottle, the first control valve closes the corresponding dispensing tube, thereby controlling the amount of different drugs added to the preparation tank and improving the accuracy of drug addition. After the different drugs are added to the preparation tank, they are initially mixed. The second control valve then opens the flow pipe, allowing the drug from the preparation tank to be added to the mixing tank for stirring.

[0028] 2. After the drugs from each vial are added to the preparation container, rotating the preparation container with the first handle can ensure that different drugs are dispersed in different areas of the preparation container, are fully mixed, and avoid local concentrations that are too high or too low.

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0036] This application discloses a pharmaceutical preparation tank with a movable agitator.

[0037] Combination Figure 1 and Figure 2 As shown, the container includes a mixing tank 1 and a base 2.

The separate drug solution mixing mechanism 3 includes a flow pipe 31 fixedly connected to the cover plate 12, a preparation tank 32 rotatably connected to the flow pipe 31, several dispensing pipes 33 fixedly connected to the preparation tank 32, and dispensing bottles 34 fixedly connected to each dispensing pipe 33. The flow pipe 31 passes through the cover plate 12. Each dispensing pipe 33 is fixedly connected to a first control valve (not shown in the figure) for controlling the opening and closing of the corresponding dispensing pipe 33. The first control valve is externally connected to a controller (not shown in the figure). The signal output terminal of the controller is connected to the signal input terminal of the first control valve. The flow pipe 31 is fixedly connected to a second control valve (not shown in the figure) for controlling the opening and closing of the flow pipe 31. The signal output terminal of the controller is connected to the signal input terminal of the second control valve. The outer surface of the preparation tank 32 is fixedly connected to a first handle 321. Each bottle 34 is connected to a vibrating ring for driving the vibration of the corresponding bottle 34. A motor is installed inside the vibrating ring. When the motor rotates inside the vibrating ring, the equipment rotates around the motor core, which will cause the center of gravity to shift, thereby generating vibration.

[0039] Combination Figure 1 and Figure 4 As shown, the mixing tank 1 is connected to a stirring mechanism 4. The stirring mechanism 4 includes a bent rod 41 rotatably connected in the stirring chamber 111 and a driving component 42 for driving the bent rod 41 to rotate. The driving component 42 is fixedly connected to the cover plate 12. The driving component 42 is a motor. The signal output terminal of the controller is connected to the signal input terminal of the driving component 42. The end of the bent rod 41 near the driving component 42 is fixedly connected to the output terminal of the driving component 42. The axis of the bent rod 41 away from the driving component 42 is located at the eccentricity of the output terminal of the driving component 42. A rotating rod 43 is fixedly connected to the end of the bent rod 41 away from the driving component 42. The axis of the rotating rod 43 is also located at the eccentricity of the output end of the driving component 42. Three sets of stirring fans 431 are connected to the outer circumferential surface of the rotating rod 43. The three sets of stirring fans 431 are distributed along the length direction of the rotating rod 43. The distance between two adjacent sets of stirring fans 431 is equal. Each set of stirring fans 431 has six stirring fans 431. The six stirring fans 431 are fixedly connected to the outer circumferential surface of the rotating rod 43 and are evenly distributed around the outer circumferential surface of the rotating rod 43.

[0040] Combination Figure 4 and Figure 5As shown, three sets of connecting rods 432 are connected to the outer surface of the rotating rod 43. The three sets of connecting rods 432 are distributed along the length of the rotating rod 43, and the distance between each adjacent set of connecting rods 432 is equal. There is one set of connecting rods 432 between two adjacent sets of stirring fans 431, and one set of stirring fans 431 between two adjacent sets of connecting rods 432. Each set of connecting rods 432 has six connecting rods 432, which are fixedly connected to the outer circumference of the rotating rod 43. The six connecting rods 432 are evenly distributed around the axis of the rotating rod 43. Each connecting rod 432 is inclined relative to the axis of the rotating rod 43, and the end of the connecting rod 432 away from the rotating rod 43 is lower than the end of the connecting rod 432 closer to the rotating rod 43. Each connecting rod 432 has a stirring rod 433 fixedly connected to one end away from the rotating rod 43, and a telescopic rod 434 movably connected to one end of the stirring rod 433 away from the connecting rod 432. A movable rod 435 is fixedly connected to one end of the telescopic rod 434 away from the stirring rod 433.

[0041] The implementation principle of the drug preparation tank with a movable stirring paddle in this application embodiment is as follows:

[0042] Different drugs are added to different dispensing bottles 34, and the vibrating ring drives the corresponding dispensing bottle 34 to vibrate. The controller controls the first control valve to open, so that the drugs in the dispensing bottles 34 flow into the preparation tank 32 through the dispensing pipe 33. When a certain amount of drugs have flowed through the dispensing bottles 34, the first control valve controls the corresponding dispensing pipe 33 to close, thereby controlling the amount of different drugs added to the preparation tank 32. Rotating the preparation tank 32 by the first handle 321 initially mixes the drugs within it. The controller then opens the second control valve, allowing the drugs from the preparation tank 32 to flow into the stirring chamber 111 and mix with the water there. The controller also activates the drive unit 42, which in turn drives the bent rod 41 to rotate. This causes the rotating rod 43, stirring fan 431, connecting rod 432, stirring rod 433, telescopic rod 434, and movable rod 435 to rotate. The telescopic rod 434 and the movable rod extend a certain length depending on the rotation speed of the rotating rod 43. The extended movable rod 435 can mix the drugs in the mixing tank 1 at different locations, increasing the contact area with the drugs and improving the mixing effect. Rotating the mixing tank 1 by the second handle 113 further enhances the mixing effect of the drugs within it.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
