Description

Technical Field

[0001] This utility model relates to the field of intravenous drug preparation technology, and in particular to a modular preparation device. Background Technology

[0002] Intravenous medication is a common treatment method. The rate of intravenous infusion for inpatients in hospitals at level 2 and above is about 90%. The preparation process is mainly concentrated in the intravenous preparation center. At present, automated and intelligent preparation equipment has begun to be used in hospitals and is constantly being optimized with different usage environments and patient needs.

[0003] The automated solution preparation system consists of three independent stations: a drug loading station, a solution preparation station, and a drug dispensing station. The drug loading station uses ampoules (5-50ml) and vials (1-30ml) placed on a tray, which is then placed in a basket rack with four layers, each containing a suitable tray. The solution preparation station then injects the solution from the vials into a liquid bag, and finally, the liquid bag is removed and used at the drug dispensing station.

[0004] However, in actual use, staff place the medicine bottles (ampoules, vials) and liquid bags into trays according to the prescription. The trays need to be removed manually, the medicine bottles are placed in the slots on the trays, and then the trays are manually lifted and placed into the basket rack. If the prescription contains a small amount of medicine, only one or two trays need to be removed. If the prescription contains a large amount of medicine, staff need to remove all four trays from the basket rack, place the medicine bottles into the trays according to the prescription, and then place the four trays back into the basket rack. This method is particularly inconvenient, time-consuming, and labor-intensive when the dosage is large, thus affecting the subsequent preparation and use of the medicine.

[0005] Therefore, this application provides a modular liquid preparation device to meet the requirements. Utility Model Content

[0006] The technical problem this invention aims to solve is to provide a modular dispensing device that addresses the issue that existing methods require manual removal of trays, placement of medicine bottles into slots on the tray, and then manual lifting of the tray into a basket rack. If the prescription contains a small amount of medicine, only one or two trays need to be removed; however, if the prescription contains a large amount of medicine, all four trays must be removed from the basket rack, medicine bottles must be placed into the trays according to the prescription, and then the four trays must be placed back into the basket rack. This method is particularly inconvenient, time-consuming, and labor-intensive when dealing with large dosages, thus affecting the subsequent dispensing and use of the medicine.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A modular liquid dispensing device includes a dispensing station module, a loading station module, and a dispensing station module. The loading station module connects the various stations via a conveyor line and transports medicine bottles. The dispensing station module automatically dispenses the liquid and sets up dedicated stations as needed. The dispensing station module transports the dispensed liquid bags, labels them, and discharges them from the device. A basket frame is installed in the middle of the loading station module. A tray is installed on the inner wall of the basket frame. A reinforcing block is installed in the middle of the outer wall of the basket frame. A liquid bag is fixedly connected to the top of the tray. A support chamber is fixedly connected to the inner wall of the groove block on the basket frame. An auxiliary rotating component is used to change the position of the basket frame. The auxiliary rotating component is connected to the basket frame and the reinforcing block.

[0009] Optionally, the auxiliary rotation assembly includes an abutting post that fits into the middle position of the reinforcing block, a rotating post that is rotatably connected to the middle position of the reinforcing block, a hollow post that is fixedly connected to the inner wall of the middle position of the reinforcing block, a balancing side plate that is fixedly connected to the outer wall of the hollow post, a force-bearing platform that is fixedly connected to the inner wall of the middle position of the reinforcing block, and a weakening part that is provided at the end of the force-bearing platform.

[0010] Optionally, a support compartment is fixedly connected to the inner wall of the groove block on the flower basket frame, and a snap-fit ​​block is fixedly connected to the top of the reinforcing block.

[0011] Optionally, a support ring is fixedly connected to the middle position of the outer wall of the flower basket frame.

[0012] Optionally, an adapter pad is attached to the inner wall of the bearing ring, a placement ball is attached to the inner wall of the adapter pad, and a deformation pad is fixedly connected to the outer wall of the placement ball.

[0013] Optionally, a slot is provided in the middle of the flower basket frame, a connecting groove is provided on the inner wall of the slot, a buffer plate is fixedly connected to the inner wall of the connecting groove, a connecting spring is fixedly connected to the outer wall of the buffer plate, and a friction pad is fixedly connected to the outer wall of the buffer plate.

[0014] Optionally, the rotating column passes through the middle of the reinforcing block, and the upper and lower ends of the rotating column are fixedly connected to the middle of the flower basket frame. The abutting column is a solid body, and the balancing side plates are symmetrically fixedly connected to the outer wall of the hollow column.

[0015] Optionally, the top of the snap-fit ​​block is attached to the inner wall of the slot block on the flower basket frame, and the bottom of the support compartment is attached to the top of the rotating column.

[0016] Optionally, the end of the adapter pad near the flower basket frame is snapped onto the outer wall of the flower basket frame, the top of the deformation pad is fixedly connected to the inner wall at the middle position of the flower basket frame, and a snap-fit ​​groove is provided at the position of the ball placement near the tray, and the size of the snap-fit ​​groove is adapted to the size of the tray.

[0017] Optionally, the buffer plates are symmetrically distributed vertically and are arc-shaped, and the top and bottom of the connecting springs are fixed to the outer walls of the distributed buffer plates.

[0018] Compared with the prior art, this utility model has at least the following beneficial effects:

[0019] In the above scheme, by setting up an auxiliary rotating component, the staff determines the required amount of ampoules and vials of medicine according to the prescription. Then, the tray is rotated from the inner wall of the basket rack to the outer wall, the medicine bottles are placed, and then the tray is rotated counterclockwise to reset it. This method can avoid the situation where, when there is too much medicine, the tray has to be removed one by one to place the medicine bottles and then put back on the basket rack one by one. It saves time and effort, improves the comfort of the staff when placing medicine bottles, and also improves the efficiency of placing medicine bottles. This ensures the subsequent preparation and use of medicine. In addition, in the entire modular preparation device, the auxiliary rotating component can improve the medicine loading efficiency of the medicine loading station module, which is conducive to the preparation efficiency of the subsequent preparation station module and the outflow of medicine bottles from the medicine dispensing station module.

[0020] By incorporating rotating columns, contact columns, hollow columns, and a force-bearing platform into the auxiliary rotating assembly, the placement of medicine bottles becomes convenient and quick, eliminating the need for staff to move trays up and down, thus improving the progress of subsequent solution preparation. Compared to the previous method of handling and placing medicine bottles, the rotation method saves staff time and effort in the subsequent bottle placement process. When there are many prescriptions or patients take medication frequently, the placement of medicine bottles can be ensured. Furthermore, the overall size of the equipment is moderate, and the production and connection between the parts are relatively simple, avoiding production difficulties and time-consuming and labor-intensive processes.

[0021] By incorporating a buffer plate, connecting groove, connecting spring, and friction pad, the tray begins to slow down when it rotates to contact the buffer plate. This mitigates the risk of the tray hitting the outer wall groove of the flower basket frame after a full rotation due to excessive speed during rotation. This prevents damage to the flower basket frame and the tray, and also avoids damage to the reinforcing blocks from impacts, ensuring the stability of all components. Attached Figure Description

[0055] like Figures 1 to 24As shown, an embodiment of this utility model provides a modular liquid dispensing device, including a liquid dispensing station module 1, a drug loading station module 2, and a drug dispensing station module. The drug loading station module connects the various station devices via a conveyor line and conveys medicine bottles. The liquid dispensing station module automatically dispenses liquid and sets up dedicated stations as needed. The liquid dispensing station module conveys the dispensed liquid bags, labels them, and discharges them from the device. A basket frame 3 is installed in the middle of the drug loading station module 2. A tray 4 is installed on the inner wall of the basket frame 3. A reinforcing block 5 is installed in the middle of the outer wall of the basket frame 3. A liquid bag 6 is fixedly connected to the top of the tray 4. A support chamber 508 is fixedly connected to the inner wall of the upper groove block of the basket frame 3. An auxiliary rotating component is used to change the position of the basket frame 3. The auxiliary rotating component is connected to the basket frame 3 and... The reinforcing block 5 is connected. The dispensing station module 1, the medicine dispensing station module 2, and the basket rack 3 are all existing structures. The main usage is that the basket rack 3 is installed on the medicine dispensing station module 2. When placing medicine bottles, the basket rack 3 cannot be removed; instead, the tray 4 on the basket rack 3 is removed directly. Then, the intelligent drive device on the medicine dispensing station module 2 moves the basket rack 3 from one position to another. The actual size of the basket rack 3 can be changed in a timely manner according to the actual size of the ampoules and vials. Several grooves are opened on the side of the basket rack 3, and the number and size of the grooves on different sides are different. The size of the grooves on the inner side of the basket rack 3 is the same as the size of the tray 4, facilitating the sliding of the tray 4. The grooves at the four corners of the basket rack 3 are different, such as... Figure 9 As shown in the magnified view, the groove on the left side of the flower basket frame 3 has a small opening angle and does not separate the flower basket frame 3. However, the groove on the right side of the flower basket frame 3 has a large opening angle and has separated the flower basket frame 3. Therefore, the overall stable connection of the flower basket frame 3 mainly relies on the fixation on the left side of the flower basket frame 3 and the connection of a small part of the reinforcing block 5. The tray 4 is used in conjunction with the flower basket frame 3. The tray 4 is slidably attached to the flower basket frame 3, and there are four sets of trays 4 on the flower basket frame 3. The reinforcing block 5 rotates on the groove of the flower basket frame 3 and is made of rigid material. A groove is opened in the middle of one side of the reinforcing block 5 for attaching the sliding tray 4. The other side of the reinforcing block 5 is larger. The liquid bag 6 is fixed on the tray 4, and part of the top of the tray 4 is for placing ampoules and vials, and the other part is for placing the liquid bag 6. The bearing ring 7 is fixed in the middle of the flower basket frame 3 near the outer wall of the groove.

[0056] The solution preparation system mainly consists of three parts: the drug loading station, the solution preparation station, and the drug dispensing station. Figure 1 This can be used as a reference, but it is not a complete flowchart for the solution preparation process. The drug loading station 2 is located on the left, the middle position has two solution preparation stations, and the right side has a drug dispensing station. The optimal combination is one drug loading station, three solution preparation stations and one drug dispensing station.

[0057] Specifically, the drug delivery station mainly consists of a drug bottle tray loading and unloading conveyor line, a drug bottle handling module, an intelligent liquid bag storage, a liquid bag robot, a pre-labeling module, and a tooling conveying module. It can accommodate 50ml~500ml infusion bags and supports various sizes of drug bottles, including vials (5-50ml) and ampoules (1-30ml). Up to 48 sets of drug bottle trays can be loaded at a time. Drug bottles and liquid bags of the same prescription are placed on the same tray. An optional prescription information verification function is available. The entire equipment is light-proof, which can effectively protect the drugs. The handling mechanism picks up the drug bottles and liquid bags according to the prescription and places them on the drug tooling. The tooling can be transferred to the corresponding dispensing station for dispensing as needed.

[0058] The dispensing station mainly consists of an ampoule dispensing robot, a penicillin dispensing module, a penicillin shaking table, a penicillin handling module, an ampoule opening module, a liquid bag handling module, a tooling conveying module, a weighing module, and a syringe conveying module. It is recommended that the automated dispensing equipment handle most prescription needs, while special prescriptions are dispensed manually or using dedicated off-line equipment. It is compatible with both penicillin and ampoules, allowing for multiple dispensing methods or mixed dispensing. It can also be customized to be a dedicated penicillin or ampoule dispensing station, with a streamlined structure that saves space and cost. A standard vision module verifies bottle information, and a standard weighing table verifies the volume of liquid drawn. The penicillin or ampoule dispensing modules operate independently and can perform dispensing simultaneously, improving efficiency. Syringes are fed from the dispensing station and conveyed to this station via the syringe conveying module. Pharmaceutical tooling is conveyed from the previous station to the dispensing station, and the tooling handling module transports the liquid bag to the dispensing position. After dispensing, the liquid bag flows to the next station along with the pharmaceutical tooling.

[0059] The dispensing station mainly consists of a liquid bag handling module, a labeling and unloading module, a tooling circulation module, and a syringe feeding module. It generates QR code labels in real time for easy tracking of liquid preparation information. An optional weighing module can be added to verify the liquid dosage. The syringe feeding module removes the needle cap from the syringe, adjusts the angle, and places it into the syringe tooling before transferring it to the liquid preparation station. The same syringe is used for preparing penicillin ampoules. The drug tooling is transported from the previous station to the dispensing station. The dispensing robot takes away the liquid bag, labels it, and it flows out of the equipment. The tooling flows back to the loading station through the tooling circulation module.

[0060] The main operating procedure is as follows: First, the operator starts the equipment. Then, the medicine tray and liquid bag syringe are loaded into the relevant equipment. After preparation, the tray is removed from the medicine loading module in the medicine loading station, and the ampoules and liquid bags are placed into the medicine bottle fixture. Similarly, if vials are present, they are handled in the same way. The tray is then returned to its original position and enters the liquid preparation module in the liquid preparation station. The relevant medicine bottles are verified, and the system is automatically transported to the bottle opening module. The ampoules are then automatically opened and broken, and a robot picks up the syringe to extract the liquid. After extraction, the syringe is disposed of in a collection box. Finally, the liquid bag is placed into the discharge conveyor line via the transport module in the medicine dispensing station. Labels are automatically printed and affixed, and the liquid bag flows out of the equipment. This is the complete process of the overall liquid preparation system.

[0061] With the above structure, staff determine the required number of ampoules and vials based on the prescription. After determining the number of vials, rotate tray 4 clockwise to 90°, so that tray 4 moves from the inner wall of the basket rack 3 to the outer wall of the basket rack 3. After placing the vials, rotate it counterclockwise to reset it. This method avoids the need to remove tray 4 one by one to place the vials and then put tray 4 back on the basket rack 3 when there are too many vials. It saves time and effort, improves the comfort of staff when placing vials, and also improves the efficiency of placing vials. This ensures the subsequent preparation and use of the medication. In addition, in the entire modular preparation device, the auxiliary rotating component can improve the medication loading efficiency of the loading station module, which is conducive to the preparation efficiency of the subsequent preparation station module and the outflow of vials from the dispensing station module.

[0062] like Figures 14 to 20 , Figure 23 and Figure 24As shown, the auxiliary rotation assembly includes an abutment post 502 attached to the middle position of the reinforcing block 5, a rotating post 501 rotatably connected to the middle position of the reinforcing block 5, a hollow post 503 fixedly connected to the inner wall of the middle position of the reinforcing block 5, a balance side plate 504 fixedly connected to the outer wall of the hollow post 503, a force-bearing platform 505 fixedly connected to the inner wall of the middle position of the reinforcing block 5, a weakening part 506 provided at the end of the force-bearing platform 505, and a snap-fit ​​block 50 fixedly connected to the top of the reinforcing block 5. 7. A bearing ring 7 is fixedly connected to the middle position of the outer wall of the flower basket frame 3. An adapter pad 701 is attached to the inner wall of the bearing ring 7. A ball placement 703 is attached to the inner wall of the adapter pad 701. A deformation pad 702 is fixedly connected to the outer wall of the ball placement 703. The end of the adapter pad 701 near the flower basket frame 3 is snapped onto the outer wall of the flower basket frame 3. The top of the deformation pad 702 is fixedly connected to the inner wall of the middle position of the flower basket frame 3. A snap-fit ​​groove is opened on the ball placement 703 near the tray 4, and the size of the snap-fit ​​groove is... The dimensions of the rotating column 501 are adapted to the size of the tray 4. The rotating column 501 passes through the middle of the reinforcing block 5. The upper and lower ends of the rotating column 501 are fixedly connected to the middle of the flower basket frame 3. The abutting column 502 is a solid body. The balancing side plates 504 are symmetrically fixed to the outer wall of the hollow column 503. The top of the snap-fit ​​block 507 is attached to the inner wall of the groove block on the flower basket frame 3. The bottom of the support compartment 508 is attached to the top of the rotating column 501. The top and bottom of the rotating column 501 are fixed to the groove block of the flower basket frame 3. The reinforcing block 5 rotates on the rotating column 501. The abutting column 502, the hollow column 503, the balancing side plate 504, the force-bearing platform 505 and the weakening part 506 are symmetrically distributed in the middle of the side of the reinforcing block 5, divided into upper and lower parts. The spacing between the abutting column 502, the hollow column 503 and the force-bearing platform 505 is consistent with the thickness of the tray 4. The bottom of the snap-fit ​​block 507 is fixed to the top of the reinforcing block 5, and the bottom of the support compartment 508 is attached to the top of the reinforcing block 5.

[0063] With the above structure, in the initial state, tray 4 is located on the inner wall of the flower basket frame 3, and the position of the flower basket frame 3 is consistent with the position of tray 4. One end of the outer wall of tray 4 is attached to the groove on the side of the reinforcing block 5, and the abutment post 502, the balance side plate 504, and the force-bearing platform 505 firmly fix tray 4. The other end of the outer wall of tray 4 is snapped into the snap-fit ​​groove of the ball placement 703, and a friction pad is provided on the snap-fit ​​groove of the ball placement 703. Under the action of the friction pad, the fixing ability of tray 4 is improved, and when tray 4 moves, it will drive the movement of the ball placement 703. Under the above three structures, tray 4 will not slide horizontally at will. When it is necessary to place medicine bottles on tray 4, the workmanship is smooth. The operator manually rotates tray 4 clockwise. During rotation, the contact post 502 and the force-bearing platform 505 inside the reinforcing block 5 groove provide the main fixing conditions. Since the contact post 502 and the force-bearing platform 505 are made of rigid material, the rotation of tray 4 will not cause them to deform. As tray 4 continues to rotate, the reinforcing block 5 and tray 4 deflect synchronously, and the placement ball 703 located at the opposite end of tray 4 also rotates. The center of rotation is the rotating post 501. The rotation is done manually by the operator. At this time, there is also a liquid bag 6 on tray 4. The height of the liquid bag 6 is consistent with the length of the slot on the flower basket frame 3, and it does not obstruct the rotation of tray 4. Figure 23To rotate tray 4 to a half-angle (45°), at this point, tray 4 only has the liquid bag 6 on it and no medicine bottle. The entire load-bearing support of tray 4 mainly relies on the contact between the end of tray 4 and the contact post 502, the hollow post 503, the force-bearing platform 505, and the weakened part 506. After rotation, the ball 703 placed at the other end of tray 4 also detaches from the inner wall of the bearing ring 7. As a result, tray 4 will sink and tilt downwards. The sinking and tilting end is the end near the ball 703, and the other end tilts upwards. When tilting upwards, the end of tray 4 will compress and deform the force-bearing platform 505 and the weakened part 506. The deformation and compression of the weakened part 506 are particularly noticeable. The effect of the deformed and compressed weakened part 506 is greater in the middle than on the sides. Therefore, after the end of tray 4 contacts the middle of the weakened part 506, the lifting of the sides will increase the load on tray 4. The friction between the weakened parts 506, combined with the fact that the tray 4 is in an invisible tilted state within the groove of the reinforcing block 5 at the middle position, the lower hollow column 503 is on the outside and experiences the greatest downward pressure, while the upper weakened part 506 is on the inside and experiences the greatest upward compressive force, prevents the tray 4 from sliding out of the groove of the reinforcing block 5. Furthermore, if sliding occurs, the upper force-bearing platform 505, the balance side plate 504, and the hollow column 503 can all use blocking mechanisms to fix the position of the tray 4 within the groove of the reinforcing block 5. As mentioned above, the spacing between the upper and lower contact column 502, the hollow column 503, and the force-bearing platform 505 is consistent with the thickness of the tray 4, further effectively preventing the tray 4 from sliding out of the groove of the reinforcing block 5. Once the tray 4 rotates to the outside of the flower basket frame 3 (e.g., Figure 24At this point, the tray 4 has been completely rotated from the inner wall of the flower basket frame 3 to the outer wall of the flower basket frame 3. The rotated tray 4 fits snugly against the groove of the flower basket frame 3. At this time, the support chamber 508 fixed on the top outer wall of the rotating column 501 also successfully engages the locking block 507, which further stabilizes the tray 4 when placing medicine bottles. Finally, the medicines are placed. During the placement process, the up-and-down and left-and-right swaying of the tray 4 will not affect the placement of the medicine bottles. After placement, the tray 4 is rotated counterclockwise in the same way as before. When rotating back to the original position, the deformation pad 702 will contact the inner wall of the adapter pad 701. Furthermore, since the inner diameter of the adapter pad 701 is smaller than that of the ball placement 703, it will directly compress the adapter pad 701 upon return, increasing its inner diameter under compression. This increased diameter allows the ball placement 703 to be securely held inside the adapter pad 701. One end of the adapter pad 701 is also secured to the outer wall of the flower basket frame 3, providing it with some flexibility and preventing it from being fixed in place. This allows the adapter pad 701 to better accommodate the ball placement 703. The deformation pad 702 serves to prevent the ball placement 703 from being held inside the adapter pad 701 after it has been secured. If the entire flower basket frame 3 is in a feeding state... During delivery, there is some shaking. To prevent the overall flower basket frame 3 from impacting the medicine bottles, the force generated by the shaking is fed back to the deformation pad 702. The cushioning effect further reduces the shaking effect, thereby reducing the collision between medicine bottles on the tray 4. It is worth mentioning that the placement ball 703 is removed from the adapter pad 701 by forcefully rotating the tray 4. The rotational force causes the outer wall of the placement ball 703 to be compressed and deformed against the outer side of the adapter pad 701, thereby increasing the diameter of the side of the adapter pad 701. Then, the placement ball 703 will come out under the action of rotation. The size and shape of the bearing ring 7 and the adapter pad 701 do not completely cover the placement ball 703. Instead of simply wrapping, the device wraps most of the medicine bottle without compressing or deforming it. This improves stability and ensures that the placement ball 703 can be properly engaged and disengaged until it returns to its initial position. This makes placing medicine bottles convenient and quick, eliminating the need for staff to carry the tray 4 up and down, thus improving the progress of subsequent solution preparation. Compared to the previous method of carrying and placing medicine bottles, the rotation method saves staff time and effort in the subsequent placement process. When there are many prescriptions or patients take medication frequently, it ensures the progress of medicine bottle placement. Furthermore, the overall size of the equipment is moderate, and the production and connection between the parts are relatively simple, avoiding production difficulties and time-consuming and labor-intensive processes.

[0064] It is worth mentioning that when the tray 4 is rotated back to its original position after the medicine bottles are placed, the medicine bottles on the tray 4 will not touch the right angle of the flower basket frame 3. Furthermore, the diameter of the circle formed by the rotation trajectory of the tray 4 is greater than half the length of the flower basket frame 3. Specifically, since the center of rotation of the tray 4 is the rotating column 501, which is located at the center of the length of the flower basket frame 3, the diameter, calculated as half the length of the flower basket frame 3, should be less than the diameter calculated as the distance from the rotating column 501 to the edge of the liquid bag 6. Therefore, when the tray 4 rotates to its original position... Figure 23 At this time, the right angle of tray 4 will not rub or contact the medicine bottle on tray 4, thus avoiding tray 4 from being unable to rotate normally and affecting subsequent normal use.

[0065] like Figures 14 to 16 As shown, a slot is provided in the middle of the flower basket frame 3, and a connecting groove 302 is provided on the inner wall of the slot. A buffer plate 301 is fixedly connected to the inner wall of the connecting groove 302. A connecting spring 303 is fixedly connected to the outer wall of the buffer plate 301, and a friction pad 304 is fixedly connected to the outer wall of the buffer plate 301. The buffer plate 301 is symmetrically distributed vertically and is arc-shaped. The top and bottom of the connecting spring 303 are both distributed and fixed on the outer wall of the buffer plate 301. The buffer plate 301 and the connecting groove 302 are symmetrically distributed vertically in the slot of the flower basket frame 3. The connecting spring 303 is hollow. The buffer plate 301 is made of a rigid material. The friction pads 304 are fixed on the buffer plate 301, with two on the top and two on the bottom, for a total of four. With the above structure, when the tray 4 rotates to the outside of the flower basket frame 3, the outer wall of the tray 4 will contact the buffer plate 301. Combined with the fact that the outer end of the buffer plate 301 extends to both sides... When bent, the tray 4 easily enters the buffer plate 301 during rotation without needing to adjust its position. The distance between the upper and lower buffer plates 301 is slightly smaller than the thickness of the tray 4. After the tray 4 enters the buffer plate 301, its thickness supports the upper and lower buffer plates 301, which in turn pulls the connecting spring 303 straight in both directions. When the tray 4 enters the buffer plate 301, its friction pad 304 further restricts its movement. Under these restrictions, the tray 4 begins to slow down when it rotates to contact the buffer plate 301. This mitigates the risk of the tray 4 rotating too fast and then hitting the outer wall groove of the flower basket frame 3, thus preventing damage to the flower basket frame 3 and the tray 4. It also prevents damage to the reinforcing block 5 from impact, ensuring the stability of all components.

[0066] The solution preparation method of the above-mentioned modular solution preparation device includes the following steps:

[0067] Step 1, Manual Operation: Start the equipment and load the medicine tray, liquid bag syringe, and other necessary components into the equipment;

[0068] Step 2, Medicine Station: Place the tray into the pull-out mechanism, use the transport module to grab the liquid bag and place it into the medicine fixture, then use the transport module to grab the medicine and place it into the medicine fixture, and finally the pull-out mechanism puts the tray back.

[0069] Step 3, Dispensing Station: The system automatically verifies the information of the medicine bottle and moves it to the bottle opening module; the ampoules are automatically opened and broken; the vials are automatically capped; the robot extracts the medicine; the dispensing module injects the medicine into the liquid bag; and the weight is determined.

[0070] Step 4, Discharge Station: The transport module picks up the liquid bag, puts it into the discharge conveyor line, automatically prints and affixes a label, and finally the liquid bag flows out of the equipment.

[0071] The working principle of the technical solution provided by this utility model is as follows:

[0072] In its initial state, tray 4 is located on the inner wall of the flower basket frame 3, and the position of the flower basket frame 3 is consistent with the position of tray 4. One end of the outer wall of tray 4 is attached to the groove on the side of the reinforcing block 5, and the abutment post 502, the balancing side plate 504, and the force-bearing platform 505 firmly fix tray 4. The other end of the outer wall of tray 4 is snapped into the snap-fit ​​groove of the ball placement 703, and a friction pad is provided on the snap-fit ​​groove of the ball placement 703. Under the action of the friction pad, the fixing ability of tray 4 is improved, and when tray 4 moves, it will drive the ball placement 703 to move. Under the above three structures, tray 4 will not slide horizontally at will. When it is necessary to place medicine bottles on tray 4, the staff The tray 4 is manually rotated clockwise. During rotation, the contact post 502 and the force-bearing platform 505 inside the reinforcing block 5 groove are the main fixing conditions. Since the contact post 502 and the force-bearing platform 505 are made of rigid material, the rotation of the tray 4 will not cause them to deform. As the tray 4 continues to rotate, the reinforcing block 5 and the tray 4 deflect synchronously, and the placement ball 703 located at the opposite end of the tray 4 also rotates. The center of rotation is the rotating post 501. The rotation is done manually by the operator. At this time, the liquid bag 6 is also present on the tray 4. The height of the liquid bag 6 is consistent with the length of the slot on the flower basket frame 3, and it will not obstruct the rotation of the tray 4. Figure 23To rotate tray 4 to a half-angle (45°), at this point, tray 4 only has the liquid bag 6 on it and no medicine bottle. The entire load-bearing support of tray 4 mainly relies on the contact between the end of tray 4 and the contact post 502, the hollow post 503, the force-bearing platform 505, and the weakened part 506. After rotation, the ball 703 placed at the other end of tray 4 also detaches from the inner wall of the bearing ring 7. As a result, tray 4 will sink and tilt downwards. The sinking and tilting end is the end near the ball 703, and the other end tilts upwards. When tilting upwards, the end of tray 4 will compress and deform the force-bearing platform 505 and the weakened part 506. The deformation and compression of the weakened part 506 are particularly noticeable. The effect of the deformed and compressed weakened part 506 is greater in the middle than on the sides. Therefore, after the end of tray 4 contacts the middle of the weakened part 506, the lifting of the sides will increase the load on tray 4. The friction between the weakened parts 506, combined with the fact that the tray 4 is in an invisible tilted state within the groove of the reinforcing block 5 at the middle position, the lower hollow column 503 is on the outside and experiences the greatest downward pressure, while the upper weakened part 506 is on the inside and experiences the greatest upward compressive force, prevents the tray 4 from sliding out of the groove of the reinforcing block 5. Furthermore, if sliding occurs, the upper force-bearing platform 505, the balance side plate 504, and the hollow column 503 can all use blocking mechanisms to fix the position of the tray 4 within the groove of the reinforcing block 5. As mentioned above, the spacing between the upper and lower contact column 502, the hollow column 503, and the force-bearing platform 505 is consistent with the thickness of the tray 4, further effectively preventing the tray 4 from sliding out of the groove of the reinforcing block 5. Once the tray 4 rotates to the outside of the flower basket frame 3 (e.g., Figure 24At this point, the tray 4 has been completely rotated from the inner wall of the flower basket frame 3 to the outer wall of the flower basket frame 3. The rotated tray 4 fits snugly against the groove of the flower basket frame 3. At this time, the support chamber 508 fixed on the top outer wall of the rotating column 501 also successfully engages the locking block 507, which further stabilizes the tray 4 when placing medicine bottles. Finally, the medicines are placed. During the placement process, the up-and-down and left-and-right swaying of the tray 4 will not affect the placement of the medicine bottles. After placement, the tray 4 is rotated counterclockwise in the same way as before. When rotating back to the original position, the deformation pad 702 will contact the inner wall of the adapter pad 701. Furthermore, since the inner diameter of the adapter pad 701 is smaller than that of the ball placement 703, it will directly compress the adapter pad 701 upon return, increasing its inner diameter under compression. This increased diameter allows the ball placement 703 to be securely held inside the adapter pad 701. One end of the adapter pad 701 is also secured to the outer wall of the flower basket frame 3, providing it with some flexibility and preventing it from being fixed in place. This allows the adapter pad 701 to better accommodate the ball placement 703. The deformation pad 702 serves to prevent the ball placement 703 from being held inside the adapter pad 701 after it has been secured. If the entire flower basket frame 3 is in a feeding state... During delivery, there is some shaking. To prevent the overall flower basket frame 3 from impacting the medicine bottles, the force generated by the shaking is fed back to the deformation pad 702. The cushioning effect further reduces the shaking effect, thereby reducing the collision between medicine bottles on the tray 4. It is worth mentioning that the placement ball 703 is removed from the adapter pad 701 by forcefully rotating the tray 4. The rotational force causes the outer wall of the placement ball 703 to be compressed and deformed against the outer side of the adapter pad 701, thereby increasing the diameter of the side of the adapter pad 701. Then, the placement ball 703 will come out under the action of rotation. The size and shape of the bearing ring 7 and the adapter pad 701 do not completely cover the placement ball 703. Instead of simply wrapping, the device wraps most of the medicine bottle without compressing or deforming it. This improves stability and ensures that the placement ball 703 can be properly engaged and disengaged until it returns to its initial position. This makes placing medicine bottles convenient and quick, eliminating the need for staff to carry the tray 4 up and down, thus improving the progress of subsequent solution preparation. Compared to the previous method of carrying and placing medicine bottles, the rotation method saves staff time and effort in the subsequent placement process. When there are many prescriptions or patients take medication frequently, it ensures the progress of medicine bottle placement. Furthermore, the overall size of the equipment is moderate, and the production and connection between the parts are relatively simple, avoiding production difficulties and time-consuming and labor-intensive processes.

[0073] It is worth mentioning that when the tray 4 is rotated back to its original position after the medicine bottles are placed, the medicine bottles on the tray 4 will not touch the right angle of the flower basket frame 3. Furthermore, the diameter of the circle formed by the rotation trajectory of the tray 4 is greater than half the length of the flower basket frame 3. Specifically, since the center of rotation of the tray 4 is the rotating column 501, which is located at the center of the length of the flower basket frame 3, the diameter, calculated as half the length of the flower basket frame 3, should be less than the diameter calculated as the distance from the rotating column 501 to the edge of the liquid bag 6. Therefore, when the tray 4 rotates to its original position... Figure 23 At this time, the right angle of tray 4 will not rub or contact the medicine bottle on tray 4, thus avoiding tray 4 from being unable to rotate normally and affecting subsequent normal use.

[0074] When tray 4 rotates to the outside of the flower basket frame 3, the outer wall of tray 4 will contact the buffer plate 301. Combined with the fact that the outer end of the buffer plate 301 extends to both sides, tray 4 can easily enter the buffer plate 301 when rotating without needing to deliberately adjust its position. Furthermore, the distance between the upper and lower buffer plates 301 is slightly smaller than the thickness of tray 4. After tray 4 enters the buffer plate 301, the thickness of tray 4 will support the upper and lower buffer plates 301. The supported buffer plates 301 will drive the connecting spring 303 to straighten in both directions. When tray 4 enters the buffer plate 301, its friction pad 304 will further restrict the movement of tray 4. Under these restrictions, tray 4 will begin to slow down when it rotates to contact the buffer plate 301. This will prevent the tray 4 from rotating too fast and then hitting the outer wall groove of the flower basket frame 3 after one full rotation, thus avoiding damage to the flower basket frame 3 and tray 4. It will also prevent damage to the reinforcing block 5 from the impact, ensuring the stability of each component.
