Description

Technical Field

[0001] This utility model relates to the field of drug concentration technology, specifically a drug concentration machine for drug preparation. Background Technology

[0002] A drug concentrator works by heating the solution to evaporate the solvent (usually water), thus reducing the amount of solvent and increasing the concentration of the active ingredient. This process typically involves using an evaporator, such as an MVR evaporator, a multi-effect evaporator, or a triple-effect evaporator. These evaporators effectively remove the solvent while retaining the active ingredient in the drug.

[0003] For example, utility model application number 202420880996.9 provides a drug concentrator for drug production, including a concentrator tank for concentrating concentrated substances. A transparent observation window is provided on the outer wall of the concentrator tank, and a sampling port is provided on the top of the tank. A sealing plug is provided inside the sampling port, and a sampling mechanism for extracting concentrated liquid at different depths within the tank is inserted into the sealing plug. An indicator component is provided on the outside of the sampling mechanism to display the extraction depth. This utility model allows for the extraction of concentrated liquid at different heights within the tank through the sampling mechanism and the indicator component, facilitating real-time sampling and testing of the concentrated liquid concentration based on the concentration status. It eliminates the need for repeated start-up and shutdown for concentration operations, simplifying operation and increasing efficiency. However, drug concentrators often require adding drugs midway through the concentration process, necessitating opening the top cover of the concentrator to add the drugs, resulting in significant heat loss and cumbersome operation.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 and Figure 2As shown, a drug concentrator for drug preparation includes a concentrator body 1, a top cover 2, a gear ring 3, an auxiliary cylinder 4, an auxiliary adjustment component 5, an internal plate 501, a connecting pipe 502, a threaded rod 503, a threaded disc 504, an installation pipe 6, a valve 7, an inlet pipe 8, an adjustment component 9, a fixing plate 901, a hydraulic rod 902, an auxiliary disc 903, a pinion 10, and a drive motor 11. The gear ring 3 is rotatably mounted on the outer surface of the concentrator body 1, and the pinion 10 is meshed on the outer surface of the gear ring 3. The top cover 2 is located on the top of the concentrator body 1, and the installation pipe 6 is threadedly installed inside the top cover 2. A drive motor 11 is installed in the middle of the pinion 10. An auxiliary dispensing component 5 for assisting in the administration of medication is installed at the output end of the drive motor 11. The auxiliary dispensing component 5 includes an internal plate 501, a connecting pipe 502, a threaded rod 503, and a threaded disc 504. The connecting pipe 502 is installed in the middle of the internal plate 501, and a threaded disc 504 is provided at the bottom of the connecting pipe 502. The connecting pipe 502 has a "U"-shaped structure, and the internal plate 501 is installed at the end of the connecting pipe 502. A threaded rod 503 is threadedly installed in the middle of the threaded disc 504, and a drive motor 11 is located at the bottom of a set of threaded rods 503. 1. A pinion 10 is installed at the output end of the drive motor 11. The auxiliary cylinder 4 is located outside the built-in plate 501. The auxiliary cylinders 4 are arranged in a ring around the center of the top cover 2, and the auxiliary cylinders 4 and the auxiliary adjustment components 5 are distributed in a one-to-one correspondence. An installation tube 6 is installed at the bottom of the auxiliary cylinder 4, and a valve 7 is provided on one side of the installation tube 6. An inlet tube 8 is installed at the bottom of the installation tube 6. The auxiliary cylinder 4 contains the medicine to be added midway. The drive motor 11 is designed to drive a set of pinions 10 to rotate. Through the design of the pinion 10 meshing with the gear ring 3, the gear ring 3 moves accordingly, thus rotating the ring. The small gears 10, arranged in a circular pattern, rotate synchronously, which in turn drives the threaded rod 503 connected to the small gears 10 to rotate synchronously. The rotation of the threaded rod 503 drives the threaded disc 504, the connecting pipe 502, and the built-in plate 501 to move downward or upward inside the auxiliary cylinder 4. By opening the valve 7, the built-in plate 501 can move downward or upward inside the auxiliary cylinder 4, making it easy to add the required drugs in the concentrator body 1. This avoids the need to open the top cover 2 for drug addition in the middle, thus avoiding contamination and heat loss. The operation is simple and facilitates quick drug addition in the middle.

[0022] like Figure 1 and Figure 3As shown, the outer surface of the concentrator body 1 is provided with an adjustment component 9 for adjusting the amount of different drugs fed. The adjustment component 9 is arranged in a ring about the center of the concentrator body 1. The adjustment component 9 includes a fixed plate 901, a hydraulic rod 902 and an auxiliary plate 903. The outer surface of the fixed plate 901 is provided with the hydraulic rod 902. The output end of the hydraulic rod 902 is equipped with the auxiliary plate 903. The auxiliary plate 903 is slidably disposed on one side of the outer surface of the concentrator body 1. The fixed plate 901 is fixedly disposed on one side of the outer surface of the concentrator body 1. The design of the hydraulic rod 902 can drive the auxiliary plate 903 and the components connected to the auxiliary plate 903 to move up or down, thereby controlling the meshing of the small gear 10 at the bottom of the threaded rod 503 with the gear ring 3. This facilitates adjustment and control according to the type and amount of drugs added during the process, which is beneficial for adjusting the type of drugs added during the process according to the needs of use and reducing the limitations of use.

[0023] In summary, the drug concentration machine for drug preparation firstly... Figures 1-3 The structure shown in the diagram has the auxiliary cylinder 4 pre-stored with the medication to be added during the process. The drive motor 11 drives a set of pinions 10 to rotate. The pinions 10 mesh with the gear ring 3, causing the gear ring 3 to follow suit. This causes the ring-shaped pinions 10 to rotate synchronously, which in turn drives the threaded rod 503 connected to the pinions 10 to rotate synchronously. The rotation of the threaded rod 503 causes the threaded disc 504, connecting pipe 502, and built-in plate 501 to move downwards or upwards within the auxiliary cylinder 4. By opening the valve 7, the built-in plate 501 can move downwards or upwards within the auxiliary cylinder 4, facilitating the addition of the medication into the main body 1 of the concentrator, avoiding the need to open the top cover 2 extensively during medication addition. Furthermore, the hydraulic rod 902 can move the auxiliary disc 903 and its connected components up or down, thereby controlling the meshing of the pinions 10 at the bottom of the threaded rod 503 with the gear ring 3, allowing for adjustments based on the type and amount of medication added during the process.
