In the production process of ornidazole injection, the solution preparation stage is crucial to ensuring drug quality, and the performance of the solution preparation device plays a decisive role. An ideal ornidazole injection solution preparation device needs to precisely control the proportions of each component and achieve efficient and uniform mixing of materials to guarantee the homogeneity of drug components and efficacy.
[0003] Currently, most existing liquid preparation devices are equipped with conventional stirring structures. The mixing rod can only achieve rotational motion in one direction. The resulting planar stirring mode is difficult to generate effective axial material lifting and radial shear force, resulting in slow material diffusion and difficulty in achieving uniform mixing of materials. Therefore, a liquid preparation device for ornidazole injection is proposed. Utility Model Content

The resulting planar stirring mode is difficult to generate effective axial material lifting and radial shear force, resulting in slow material diffusion and difficulty in achieving uniform mixing of materials.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a solution preparation device for ornidazole injection, comprising a base plate, two side plates fixedly connected to the top edge of the base plate, a solution preparation tank rotatably connected between the two side plates, a support plate fixedly connected to the top of the solution preparation tank, a mixing motor fixedly connected to the top of the support plate, a reducer fixedly connected to the output end of the mixing motor, a rotating shaft fixedly connected to the output end of the reducer, a mixing rod fixedly connected to the outer wall of the rotating shaft, a drive assembly installed on the outer wall of the rotating shaft, two storage tanks fixedly connected to the top of the solution preparation tank, a discharge pipe fixedly connected to the bottom of the storage tank, a quantitative discharge assembly provided on the outer wall of the discharge pipe, and a swing assembly installed on the rear top of the base plate;
[0006] The quantitative dispensing assembly includes two housings. The housings are fixedly connected to the top wall of the liquid mixing tank. A connecting rod is slidably connected to the inner wall of the housing. A baffle is fixedly connected to the top of the connecting rod. A spring is sleeved on the outer wall of the connecting rod.

[0008] The drive assembly includes a wedge block, which is fixedly connected to the top of the outer wall of the rotating shaft, and a groove is provided at the bottom of the wedge block.
[0009] As a further description of the above technical solution:
[0010] The swing assembly includes a bracket and a connecting plate. The bracket is fixedly connected to the rear top of the base plate, and the connecting plate is fixedly connected to the rear outer wall of the liquid preparation tank. A swing motor is fixedly connected to the top of the bracket, and a drive plate is fixedly connected to the output end of the swing motor. A connecting rod is fixedly connected to the side of the drive plate away from the swing motor, and the end of the connecting rod away from the drive plate is rotatably connected inside the connecting plate.
[0011] As a further description of the above technical solution:
[0012] The bottom of the liquid preparation tank is fixedly connected to a discharge pipe, and a valve is installed on the outer wall of the discharge pipe.
[0013] As a further description of the above technical solution:

[0020] The end of the spring away from the baffle is fixedly connected to the inner wall of the housing.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this invention, the periodic quantitative discharge of materials from the storage tank is achieved through the cooperation of the drive component and the quantitative discharge component. When the inclined block rotates, it pushes the connecting rod through the groove, overcoming the spring force to open the discharge pipe via the baffle. After the inclined block moves away, the spring returns to its original position and closes the discharge port. This ensures that the discharge volume is controlled by the baffle stroke and the discharge pipe diameter, avoiding human error and ensuring that the proportions of each component in the ornidazole injection meet the formulation requirements, thereby improving the stability of drug quality.
[0023] 2. In this invention, the spiral structure of the mixing rod and the oscillating motion of the dispensing tank form a three-dimensional mixing system. Driven by the rotating shaft, the spiral mixing rod can not only lift the material axially but also generate radial shear force to accelerate material diffusion. At the same time, the oscillating motor drives the dispensing tank to oscillate periodically through the drive plate and connecting rod, causing the material to tumble under the action of centrifugal force and inertia, thereby increasing the mixing efficiency.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1-3This utility model provides an embodiment of an ornidazole injection preparation device, comprising a base plate 1, which serves as the basic load-bearing component of the entire preparation device, supporting all other structural components. Two side plates 2 are fixedly connected to the top edge of the base plate 1, and a preparation tank 3 is rotatably connected between the two side plates 2, forming an installation space. The preparation tank 3 can rotate between the two side plates 2, providing a motion basis for subsequent mixing of the materials within the preparation tank 3. A support plate 4 is fixedly connected to the top of the preparation tank 3, and a mixing motor 5 is fixedly connected to the top of the support plate 4. A reducer 6 is fixedly connected to the output end of the mixing motor 5. The support plate 4 supports and fixes the mixing motor 5, ensuring its stability during operation. The mixing motor 5 provides power for mixing the materials within the preparation tank 3. The reducer 6 reduces the output speed of the mixing motor 5 and increases its torque. A rotating shaft 7 is fixedly connected to the output end of the reducer 6. Driven by the rotating shaft 7, the shaft rotates, which in turn drives the components connected to its outer wall to move. A mixing rod 8 is fixedly connected to the outer wall of the rotating shaft 7. The mixing rod 8 rotates under the drive of the rotating shaft 7 to stir and mix the materials in the mixing tank 3, promoting the full integration of the materials. A drive assembly is installed on the outer wall of the rotating shaft 7. The drive assembly is used to drive the quantitative discharge assembly to work, so as to realize the quantitative discharge of the materials in the storage tank 10. Two storage tanks 10 are fixedly connected to the top of the mixing tank 3. The two storage tanks 10 are used to store different materials required for the preparation of ornidazole injection. A discharge pipe 11 is fixedly connected to the bottom of the storage tank 10. The discharge pipe 11 serves as a channel for the materials in the storage tank 10 to be discharged and transported to the mixing tank 3. A quantitative discharge assembly is provided on the outer wall of the discharge pipe 11. The quantitative discharge assembly can accurately control the amount of materials discharged from the storage tank 10 through the discharge pipe 11 to ensure the accuracy of the preparation. A swing assembly is installed on the rear side of the top of the bottom plate 1. The swing assembly is used to drive the mixing tank 3 to swing, further enhancing the mixing effect of the materials in the mixing tank 3.
[0033] Reference Figures 3-5 The quantitative discharging assembly includes two housings 12, which are fixedly connected to the top wall of the liquid preparation tank 3. The housings 12 provide installation support structures for other components of the quantitative discharging assembly. A connecting rod 13 is slidably connected to the inner wall of the housing 12. The connecting rod 13 can slide within the housing 12, thereby driving other subsequent components to slide. A baffle 14 is fixedly connected to the top of the connecting rod 13. The baffle 14 moves under the action of the connecting rod 13 to block or open the outlet of the discharge pipe 11, thereby controlling the discharge of materials. A spring 15 is sleeved on the outer wall of the connecting rod 13. The spring 15 is used to provide a reset elastic force for the connecting rod 13 and the baffle 14, so that the baffle 14 can automatically reset and close the outlet of the discharge pipe 11 when no external force is applied.
[0034] Reference Figures 3-5The drive assembly includes a wedge block 16, which is fixedly connected to the top of the outer wall of the rotating shaft 7. The wedge block 16 rotates together with the rotating shaft 7 and serves as the power component for driving the quantitative discharging assembly. A groove 17 is provided at the bottom of the wedge block 16. The groove 17 is used to cooperate with the connecting rod 13 in the quantitative discharging assembly. During the rotation of the wedge block 16, the connecting rod 13 is pushed to move through the groove 17, thereby driving the quantitative discharging assembly.
[0035] Reference Figure 1 The oscillating assembly includes a bracket 18 and a connecting plate 22. The bracket 18 is fixedly connected to the top rear side of the base plate 1 and provides an installation base for other components of the oscillating assembly. The connecting plate 22 is fixedly connected to the rear side of the outer wall of the mixing tank 3 and is used to connect the mixing tank 3 with other components of the oscillating assembly. A shaking motor 19 is fixedly connected to the top of the bracket 18 and provides power for the oscillation of the mixing tank 3. A drive plate 20 is fixedly connected to the output end of the shaking motor 19 and rotates under the drive of the shaking motor 19. A connecting rod 21 is fixedly connected to the side of the drive plate 20 away from the shaking motor 19 and is used to transmit the movement of the drive plate 20 to the mixing tank 3. The end of the connecting rod 21 away from the drive plate 20 is rotatably connected to the inside of the connecting plate 22, so that the rotation of the drive plate 20 can drive the mixing tank 3 to oscillate and achieve the shaking and mixing of the materials in the mixing tank 3.
[0036] Reference Figures 1-3 The bottom of the mixing tank 3 is fixedly connected to a discharge pipe 9, which serves as a channel for discharging materials after the mixing is completed. The mixed ornidazole injection solution in the mixing tank 3 is transported to subsequent use or storage equipment. A valve is installed on the outer wall of the discharge pipe 9, which is used to control the opening and closing of the discharge pipe 9, thereby controlling the timing and speed of material discharge.
[0037] Reference Figures 3-5 The mixing rod 8 is spiral in shape. The spiral shape of the mixing rod 8 can better stir and mix the materials during rotation, thus enhancing the mixing effect. The end of the connecting rod 13 away from the baffle 14 is slidably connected to the inner wall of the groove 17, so that the inclined block 16 can push the connecting rod 13 to move through the groove 17 when rotating, thereby driving the baffle 14 to move and realizing the control of the discharge port of the discharge pipe 11.
[0038] Reference Figure 4 and Figure 5 The height of the inclined block 16 is greater than the height of the baffle 14, ensuring that the inclined block 16 can reliably push the baffle 14 to move during rotation, thus avoiding the situation where the quantitative discharge component cannot be driven.
[0039] Reference Figure 5The outer wall of the baffle 14 is slidably connected to the inner wall of the housing 12, and the length of the baffle 14 is greater than that of the discharge pipe 11 and less than half the length of the housing 12, so that the baffle 14 can effectively block the discharge port of the discharge pipe 11, while also being able to slide reasonably within the housing 12, thereby achieving precise control of the discharge from the discharge pipe 11.
[0040] Reference Figure 5 The end of the spring 15 away from the baffle 14 is fixedly connected to the inner wall of the housing 12, ensuring that the spring 15 can provide a stable restoring elastic force for the baffle 14 and the connecting rod 13, thus ensuring the reliability of the quantitative discharge assembly.
[0041] Working principle: When using the ornidazole injection preparation device, the different materials required for ornidazole injection preparation are first stored in two storage tanks 10 respectively.
[0042] When preparing the solution, the mixing motor 5 is started. The mixing motor 5 outputs power, which is reduced in speed and increased in torque by the reducer 6, driving the rotating shaft 7 to rotate. When the rotating shaft 7 rotates, the spiral mixing rod 8 fixed on its outer wall begins to stir the space inside the solution tank 3. At the same time, the inclined block 16 fixed on the top of the outer wall of the rotating shaft 7 also rotates with the rotating shaft 7. When the inclined block 16 rotates, the groove 17 at its bottom contacts the end of the connecting rod 13 in the quantitative discharge assembly away from the baffle 14 and pushes the connecting rod 13. Since the top of the connecting rod 13 is fixedly connected to the baffle 14, and the outer wall of the connecting rod 13 is fitted with a spring 15, under the push of the inclined block 16, the connecting rod 13 overcomes the elastic force of the spring 15 and slides on the inner wall of the shell 12, causing the baffle 14 to move down, thereby opening the discharge port of the discharge pipe 11, and the material in the storage tank 10 is quantitatively discharged into the solution tank 3 through the discharge pipe 11. When the inclined block 16 continues to rotate and no longer applies a pushing force to the connecting rod 13, the spring 15 restores its elastic deformation, pushes the connecting rod 13 and the baffle 14 to reset, closes the discharge port of the discharge pipe 11, and stops the material discharge.
[0043] While the mixing motor 5 is operating, the shaking motor 19 is started. The output of the shaking motor 19 drives the drive plate 20 to rotate. The drive plate 20 transmits the rotation to the connecting plate 22 fixed to the rear side of the outer wall of the mixing tank 3 through the connecting rod 21, causing the mixing tank 3 to swing between the two side plates 2. The swinging of the mixing tank 3 and the stirring of the mixing rod 8 work together to further enhance the mixing effect of the materials in the mixing tank 3.
[0044] Once the solution is prepared, open the valve on the outer wall of the discharge pipe 9, and the mixed ornidazole injection solution will be discharged through the discharge pipe 9 and transported to subsequent use or storage equipment.
[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
