Description

Technical Field

[0001] This utility model relates to a pharmaceutical container, specifically a low-residue pharmaceutical preparation container. Background Technology

[0002] Pharmaceutical preparation tanks are typically used in clean environments that comply with Good Manufacturing Practices (GMP) for pharmaceuticals. Temperature, humidity, and air cleanliness are strictly controlled to minimize contamination risks. These tanks effectively control the mixing, dissolving, and reaction processes of materials, ensuring uniform and stable drug composition that meets pharmaceutical quality standards. The tanks and piping are cleaned and sterilized before raw materials and solvents are added sequentially according to process requirements. Stirring, heating, or cooling promotes dissolution and reaction, with real-time temperature monitoring throughout the process. Finally, the mixture is filtered or transferred to the next process to complete the preparation. The sealed design reduces external contamination, ensuring drug safety, and offers excellent scalability to adapt to different production scales, improving pharmaceutical efficiency and product consistency.

[0003] In the prior art, 201920654733.5 discloses a buffer solution preparation tank. This utility model discloses a buffer solution preparation tank, belonging to the technical field of buffer solution preparation equipment. It includes a tank body with rotating shafts on both sides and a motor at the top. The motor is electrically connected to an external power switch. A rotating column is mounted on the output shaft of the motor, and an upper stirring blade is mounted on the rotating column. A lower stirring blade is located below the upper stirring blade, and a baffle is located on the outer side of the lower stirring blade. This buffer solution preparation tank enhances the clamping effect on the solution by setting the lower stirring blade and the baffle. The lower stirring blade can move the solution upwards, and the corresponding upper stirring blade can move the solution downwards, thereby causing the solution to convection towards the center, enhancing the stirring and mixing effect. Simultaneously, the baffle diverts the convection and collision of the solution, allowing for continuous convection. By enhancing the stirring efficiency, the buffer solution preparation time is shortened.

[0004] Existing pharmaceutical preparation tanks cannot effectively spray the pharmaceutical solution into finer particles, making it impossible to control the flow rate of the solution. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a low-residue preparation tank for pharmaceutical use.

[0006] This utility model is achieved using the following technical solution: a low-residue pharmaceutical preparation tank, comprising a preparation tank body, a preparation space within the preparation tank body, a driving component (a drive motor) at the bottom of the preparation tank body, a drive guide rod with drive blades on the drive guide rod, a top platform at the top of the preparation tank body, a pharmaceutical solution preparation chamber on the top platform, a liquid transfer channel between the pharmaceutical solution preparation chamber and the preparation tank body, a drive control pump on the liquid transfer channel, and a top spray component (a top spray plate) with multiple spray nozzles on the top spray plate.

[0007] The top spray plate is provided with a threaded opening, and a spray nozzle is installed on the threaded opening by means of threads. The spray nozzle is provided with a liquid spray hole.

[0008] The mixing tank body has a mixed liquid outlet on one side, and a control valve is provided on the mixed liquid outlet. The control valve is a manually controlled rotary valve.

[0009] The bottom of the preparation tank body is provided with a support component, which is a support leg. The bottom of the preparation tank body is provided with an assembly end, and the support leg is inserted into the assembly end. The support leg and the assembly end are fixed by bolts.

[0010] The preparation tank body is provided with a secondary injection port, the secondary injection port is provided with a movable end cap, and the secondary injection port is provided with an injection liquid flow channel.

[0011] The drive blade is divided into a main blade and a secondary blade. The main blade has a side space, and the secondary blade is installed in the side space.

[0012] The secondary blade has a slender strip structure, and a stirring head is provided on the secondary blade. The stirring head is a stirring head with stirring teeth.

[0013] Compared to existing technologies, the preparation tank of this utility model achieves uniform spraying and coverage of the medicine liquid through the cooperation of the top spray plate and the multi-hole spray nozzle. Combined with the main and secondary blades driven by the drive motor, the main blades are responsible for the main mixing, while the stirring heads with stirring teeth on the slender secondary blades can refine the mixing of the medicine liquid. A liquid transmission channel is set between the medicine liquid preparation chamber and the preparation tank body. The medicine liquid is transported to the inner wall of the preparation tank through the spray nozzle via the liquid transmission channel. In this way, the flow rate and speed of the liquid transmission channel can be precisely controlled by the drive control pump during the medicine liquid transmission, ensuring that the medicine liquid is fully circulated and mixed in the preparation space. The bottom support legs are fixed to the assembly end with bolts, which makes the structure stable and easy to disassemble and maintain. The mixed medicine liquid outlet is equipped with a manual rotary valve, which is simple to operate and has good sealing performance, which is conducive to controlling the discharge process. The secondary injection port is equipped with a movable end cap, which can replenish the injection liquid without compromising the overall airtightness, which helps to improve the convenience of the pharmaceutical process.
