Description

Technical Field

[0001] The utility model belongs to the technical field of medicament mixing, and in particular relates to a pharmaceutical preparation liquid mixing device. Background Art

[0002] Pharmaceutical preparation liquid mixing devices are used in the pharmaceutical field to fully mix liquid medicines with different ingredients to ensure the uniformity and stability of the preparations, thereby ensuring the efficacy and safety of the medicines.

[0003] The pharmaceutical preparation mixing device in the prior art is generally used by fixing the mixing barrel on the mixing device. However, in actual application, it is not convenient to replace the mixing barrel for flexible use. For example, the amount of medicine that needs to be mixed each time may be different. When the amount of medicine is large, the mixing barrel may not be able to mix it at one time and needs to be mixed in batches, resulting in low mixing efficiency. When the amount of medicine is small, the mixing barrel may be large relative to the amount of medicine that needs to be mixed, which will waste more space and may also make it difficult to mix the medicine liquid evenly. Therefore, in response to the above problems, we propose a pharmaceutical preparation liquid mixing device. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a pharmaceutical preparation liquid mixing device, which is convenient for replacing the mixing barrel of appropriate size according to the amount of medicine to be mixed, thereby improving the quality and efficiency of medicine mixing.

[0006] The beneficial effects of the utility model are as follows: by placing the mixing barrel on the telescopic support frame, the driving component drives the clamping component to clamp and fix the mixing barrels of different diameters, and then the motor drives the stirring rod to stir, so that the solution is fully mixed and evenly mixed, thereby improving the quality and efficiency of medicine mixing.

[0007] In order to drive the clamping assembly to clamp and fix the mixing barrel;

[0008] As a further improvement of the above technical solution: the driving assembly includes a bidirectional screw and a second motor arranged on the telescopic support frame, both ends of the bidirectional screw are rotatably connected to the inner wall of the cavity, and one end of the bidirectional screw extends to the outside of the cavity and is connected to the second motor.

[0009] The beneficial effect of this improvement is that when the mixing barrel needs to be clamped and fixed, the motor is started, and the motor drives the bidirectional screw to rotate, thereby controlling the clamping assembly to clamp and fix the mixing barrel.

[0010] In order to clamp and fix the mixing barrel;

[0011] As a further improvement of the above technical solution: the clamping assembly includes two clamping parts arranged opposite to each other, the open ends of the two clamping parts are arranged opposite to each other, and the bottoms of the two clamping parts are provided with movable seats, and the two movable seats are threadedly connected to the bidirectional screw.

[0012] The beneficial effect of this improvement is that when the mixing barrel is placed on the telescopic support frame, the bidirectional screw rotates, driving the two movable seats to move relative to each other. At this time, the two clamping parts move relative to each other and jointly clamp the mixing barrel, so that the position of the mixing barrel remains unchanged and remains stable.

[0013] In order to adapt to mixing barrels of different diameters;

[0015] The beneficial effect of this improvement is that since mixing barrels of different sizes need to be used, when a smaller mixing barrel is used, the adjusting plate 1 and the adjusting plate 2 are adjusted to the shortest length and fixed by a locking screw. Then, when a larger mixing barrel is used, the length between the adjusting plate 1 and the adjusting plate 2 is adjusted to an appropriate length and fixed by a locking screw.
