The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0040] As shown in Figures 1-7 , the present embodiment provides a medicine preparation device, which comprises an operation box 1, a storage frame 2, a cup 3, a water mixing mechanism 4 and a mixing mechanism 5.

[0041] Please refer to Figure 1 and Figure 2 , one side of the operation box 1 is provided with an operation port 11, and the cup 3 containing simethicone powder is put into the operation port 11 to perform water mixing operation in the operation box 1, and the operation box 1 is provided with a water storage tank 12. In an embodiment, a heater is installed in the water storage tank 12 to keep the water temperature in the water storage tank 12 at 25-40°C, so as to facilitate rapid mixing of water and simethicone powder. A constant temperature medicine storage tank 15 is provided beside the water storage tank 12 for placing the cup 3 containing prepared medicine, and the constant temperature medicine storage tank 15 is a heat preservation tank, which is beneficial to maintaining the temperature of the medicine in the cup 3 for a long time. Preferably, a temperature display is further provided on the water storage tank 12, and the temperature display is electrically connected with the heater to visually present the temperature in the water storage tank 12, which is convenient for checking. It should be noted that the heater is a conventional heating device sold on the market, which will not be described in detail here.

[0042] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5The storage frame 2 is slidably installed in the operation box 1 along the direction close to or away from the operation opening 11 and is open on the side facing the operation opening 11. Specifically, a slide rail is installed on the inner wall of the operation box 1, and slide grooves are formed on the two sides of the storage frame 2. The storage frame 2 is slidably installed on the slide rail through the slide grooves.

[0043] In order to facilitate the operation of moving the storage frame 2, in an embodiment, an operation slot 13 is formed on one side of the operation box 1, and an operation handle 21 is arranged on one side of the storage frame 2. The operation handle 21 is movably arranged outside the operation slot 13. The movement of the storage frame 2 can be controlled by pulling the operation handle 21.

[0044] Please refer to Figure 1 , Figure 2 and Figure 6 The cup 3 can be placed in the storage frame 2. It should be noted that the cup 3 has a plurality of cups for respectively configuring the required medicines of each patient.

[0045] Please refer to Figure 2 and Figure 3 The water mixing mechanism 4 includes a water injection cylinder 41 and a piston 42. The water injection cylinder 41 is installed in the operation box 1 and is fixedly installed on the inner wall of the operation box 1 through a connecting seat. The piston 42 is movably inserted into one end of the water injection cylinder 41 close to the operation opening 11. One end of the piston 42 located in the water injection cylinder 41 has a piston head which is tightly attached to the inner wall of the water injection cylinder 41. The other end of the piston 42 is connected to the storage frame 2. The piston 42 can be moved by moving the storage frame 2. The other end of the water injection cylinder 41 is respectively provided with a first valve body 43 and a second valve body 44. The first valve body 43 is provided with a first conduit 45 and only allows water to flow from the water injection cylinder 41 to the first conduit 45. The other end of the first conduit 45 penetrates into the lower side of the top of the storage frame 2 to add water to the top of the cup 3. The second valve body 44 is provided with a second conduit 46 and only allows water to flow from the second conduit 46 to the water injection cylinder 41. The other end of the second conduit 46 is in communication with the water storage tank 12 to supplement water into the water injection cylinder 41.

[0046] Specifically, the first valve body 43 includes a first passage pipe 431. The two ends of the first passage pipe 431 are respectively in communication with the water injection cylinder 41 and the first conduit 45. A first blocking ring 432 is arranged in the first passage pipe 431. A first blocking piece 433 is rotatably connected to the side of the first blocking ring 432 away from the water injection cylinder 41. The second valve body 44 includes a second passage pipe 441. The two ends of the second passage pipe 441 are respectively in communication with the water injection cylinder 41 and the second conduit 46. A second blocking ring 442 is arranged in the second passage pipe 441. A second blocking piece 443 is rotatably connected to the side of the second blocking ring 442 close to the water injection cylinder 41.

[0047] In practical use, when the storage frame 2 is moved away from the operating port 11, the piston 42 will be pushed to squeeze the water in the water injection cylinder 41. The water will flow through the first valve body 43, through the first conduit 45, and be transported into the cup body 3. At this time, the second valve body 44 will prevent the water from flowing through. When the storage frame 2 is moved closer to the operating port 11, the piston 42 will be pulled out, forming a negative pressure that attracts the water in the water storage tank 12 through the second conduit 46 and through the second valve body 44 to replenish the water injection cylinder 41. At this time, the first valve body 43 will prevent the water from flowing through, thus completing the replenishment of water in the water injection cylinder 41 for the next drug preparation.

[0048] Preferably, in order to further improve the sealing performance of the water injection cylinder 41, an elastic element is provided at the rotatable connection of the first baffle 433 and the second baffle 443. The elastic element can provide an elastic force to make the first baffle 433 and the second baffle 443 respectively abut against the first retaining ring 432 and the second retaining ring 442. The elastic element can be a torsion spring.

[0049] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 The mixing mechanism 5 is used to drive the cup 3 inside the storage frame 2 to rotate. In one embodiment, the mixing mechanism 5 includes a rack 51, a first rotating column 52, and a second rotating column 53. The rack 51 is installed on the inner wall of the operation box 1 along the sliding direction of the storage frame 2. The first rotating column 52 is axially rotatably installed at the bottom of the storage frame 2 and is connected to the rack 51 through a gear 521. The second rotating column 53 is axially rotatably inserted through the bottom of the storage frame 2. The top end of the second rotating column 53 is located inside the storage frame 2 and is provided with a carrier plate 531, which can hold the cup 3. The bottom end of the second rotating column 53 is located below the storage frame 2 and is connected to the first rotating column 52 through a conveyor belt 532. By placing the cup body 3 onto the carrier tray 531, the first rotating column 52 rotates via the transmission of the rack 51 and gear 521 while the storage frame 2 is moved. This rotation, in turn, drives the second rotating column 53 to rotate via the conveyor belt 532, causing the carrier tray 531 to rotate the cup body 3. This agitates the dimethicone oil and water within the cup body 3, allowing them to mix quickly. It is important to note that the top of the cup body 3 should be as close as possible to the top of the inner cavity of the storage frame 2 to prevent spillage.

[0050] Furthermore, the top of the carrier tray 531 is provided with a sliding groove 5311, one end of which extends out of one side of the carrier tray 531. When the storage frame 2 is located at the end of its sliding path near the operation port 11, the extended end of the sliding groove 5311 faces the operation port 11. The bottom of the cup body 3 is provided with a slider 31 that matches the sliding groove 5311. By aligning the slider 31 at the bottom of the cup body 3 with the sliding groove 5311 and sliding it in, the cup body 3 can be horizontally fixed on the carrier tray 531. Preferably, the sliding groove 5311 can be a wedge-shaped groove that is narrower at the top and wider at the bottom. The shape of the slider 31 matches the sliding groove 5311, which is beneficial for further vertical fixation of the cup body 3. Furthermore, a handle 32 is provided on the side of the cup body 3 facing the end of the slider 31 to facilitate picking up the cup body 3 and to facilitate positioning.

[0051] In one embodiment, when the cup body 3 is fixed on the carrier plate 531, its axis of rotation is the same as the axis of the second rotating column 53, while the end port of the first conduit 45 located on the lower side of the top of the storage frame 2 is offset from the axis of the second rotating column 53. When water is poured into the cup body 3, it can be poured in from different positions on the top of the cup body 3, which is beneficial to make the dimethicone oil in the cup body 3 evenly contact the water and speed up the mixing speed.

[0052] Please see Figure 1 , Figure 2 , Figure 4-Figure 7 After the medicine in the cup body 3 is mixed, it needs to be sealed and stored for later use. Therefore, in one embodiment, an annular groove 33 is provided on the inner side of the cup body 3 near the top. Sealing rings 34 are provided on the upper and lower sides of the annular groove 33 respectively. The sealing rings 34 are made of silicone or rubber. A notch 35 communicating with the outside is opened on one side of the annular groove 33. The notch 35 is semi-circular. A matching sealing sheet 36 is detachably connected in the annular groove 33. The sealing sheet 36 can be inserted into the annular groove 33 from the notch 35 to seal the top of the cup body 3. It should be noted that the distance between the two sealing rings 34 should be slightly less than the thickness of the sealing sheet 36 to ensure the sealing effect.

[0053] Furthermore, to improve drug preparation efficiency and accelerate the sealing speed of the cup 3, in one embodiment, a first insertion port 22 is provided on one side of the storage frame 2, and a second insertion port 14 is provided on one side of the operation box 1. A sealing box 6 is provided outside the second insertion port 14, and a spring 61 is provided at the bottom of the inner cavity of the sealing box 6. Multiple sealing sheets 36 are stacked vertically on top of the spring 61 inside the sealing box 6. A third insertion port 62 is provided on the side of the sealing box 6 corresponding to the second insertion port 14, and a fourth insertion port 63 is provided on the opposite side. A pusher 64 is slidably inserted into the fourth insertion port 63. When the storage frame 2 is located away from the operation port 1 in its sliding path... When the storage frame 2 moves to the innermost part of the operating box 1 and all the water in the water filling cylinder 41 is poured into the cup body 3, the notch 35, the first socket 22, the second socket 14, the third socket 62, and the fourth socket 63 will be linearly aligned. Then, the push plate 64 is pushed, so that the topmost sealing plate 36 in the sealing box 6 is pushed into the annular groove 33 through the third socket 62, the second socket 14, the first socket 22, and the notch 35, thus completing the sealing of the cup body 3. Then, the push plate 64 is pulled out. Under the elastic force of the spring 61, the stacked sealing plates 36 will be pushed upward to fill the gap for the next sealing. It should be noted that the thickness of the first socket 22, the second socket 14, and the third socket 62 should be adapted to the sealing plate 36.

[0054] The present invention provides a drug preparation device. In specific use, the cup body 3 containing dimethicone powder is first placed on the carrier plate 531, and then the placement frame 2 is slowly pushed into the operating box 1. When the placement frame 2 moves, it pushes the piston 42 to squeeze the water in the water injection cylinder 41. The second valve body 44 will block the water flow, and the water flows from the first valve body 43 into the first conduit 45 and into the cup body 3 from the top of the placement frame 2. While the placement frame 2 moves inward, the cup body 3 will rotate under the drive of the mixing mechanism 5, so that the dimethicone powder can fully contact and mix with the water. When the placement frame 2 moves to the innermost part of the operating box 1, the water in the water injection cylinder 41 is completely poured into the cup body 3, and the notch 35, the first inlet 22, the second inlet 14, the third inlet 62 and the fourth inlet 63 will be linearly aligned, pushing the push plate 64, so that the innermost part of the sealed box 6 is completely filled with water. A sealing sheet 36 at the top is pushed into the annular groove 33 to seal the cup body 3. Then, the pusher 64 is pulled out. Under the elastic force of the spring 61, the stacked sealing sheets 36 will be pushed upward to fill the gap for the next sealing. The storage frame 2 is quickly pulled out of the operation box 1. The storage frame 2 will pull the piston 42 to create a negative pressure inside the water injection cylinder 41, so that the water in the water storage tank 12 enters the water injection cylinder 41 through the second conduit 46 and the second valve body 44. At the same time, the cup body 3 will rotate under the drive of the mixing mechanism 5, so that the dimethicone powder and water will rotate and mix. When the storage frame 2 moves to the operation port 11, the water injection cylinder 41 is filled with the same amount of water as before, for the next preparation of medicine. Take out the cup body 3 with the prepared medicine and sealed, and place another cup body 3 with preparation on the carrier tray 531. Repeat the above operation.

[0055] This invention utilizes the back-and-forth movement of the storage frame 2 within the operating box 1 to complete the preparation of dimethicone powder solution. By connecting the piston 42 in the water mixing mechanism 4 to the storage frame 2, the operation of drug dilution and the replenishment of water in the water injection cylinder 41 are seamlessly and interactively replaced by changing the direction of movement of the storage frame 2. This not only improves preparation efficiency but also ensures that the amount of water added each time is consistent, allowing medical staff to control the process. Through the mixing mechanism 5, the cup body 3 can be rotated while the storage frame 2 is moving, which not only allows the dimethicone powder to fully contact with water but also quickly completes the mixing of dimethicone powder and water, greatly improving preparation efficiency and reducing the workload of medical staff. Using the sealing box 6, the cup body 3 can be quickly sealed after all the water has been added, effectively preventing liquid splashing. This invention can simultaneously perform drug dilution and mixing operations during one back-and-forth movement of the storage frame 2 and seal the cup body 3 after dilution is complete, making the operation simple and the preparation efficiency high.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
