Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intravenous infusion solution preparation, in particular to a modular infusion solution preparation device and method. BACKGROUND

[0002] Intravenous infusion is a common treatment method, and the use rate of intravenous infusion for inpatients in hospitals at the second level and above is about 90%, and the infusion process is mainly concentrated in the infusion center. At present, automatic and intelligent infusion equipment has begun to be used in hospitals, and is continuously optimized with different use environments and patient needs.

[0003] Automatic infusion is divided into three independent workstations, a medicine loading station, an infusion station, and a medicine dispensing station. The medicine loading station uses ampoules (5-50ml) and penicillin bottles (1-30ml) placed in a tray, which is then placed in a flower basket rack. The flower basket rack has four layers, each layer holding one appropriate tray. The infusion station then injects the liquid in the medicine bottles into the liquid bag, and finally the medicine dispensing station takes out the liquid bag for use.

[0004] However, in actual use, the staff places the medicine bottles (ampoules, penicillin bottles) and liquid bags into the tray according to the prescription. The tray needs to be manually taken down, the medicine bottles are placed and fixed in the slot holes on the tray, and then the tray is manually lifted and placed in the flower basket rack. If the amount of medicine in the prescription is small, only one or two trays need to be taken down. If the amount of medicine in the prescription is large, the staff needs to take down all four trays from the flower basket rack, place the medicine bottles in the trays according to the prescription, and then place the four trays in the flower basket rack. This method is particularly inconvenient and time-consuming for large amounts of medicine, which affects the subsequent infusion and use of the medicine.

[0059] like Figures 1 to 24 As shown, an embodiment of the present invention 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 stations via a conveyor line and transports medicine bottles. The liquid dispensing station module automatically dispenses liquid and sets up dedicated stations as needed. The drug dispensing station module transports 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 bearing ring 7 is fixedly connected to the middle of the outer wall 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. 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 time according to the actual size of the ampoules and vials. Several slots are opened on the side of the basket rack 3, and the number and size of the slots on different sides are different. The size of the slots 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 slots 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.

[0060] The liquid preparation system is mainly composed of three parts: the medicine feeding station, the liquid preparation station and the medicine outlet station. Figure 1 It can be used as a reference, but it is not a complete process chart for liquid preparation. The medicine feeding station 2 is located on the left side, the two liquid preparation stations are in the middle position, and the medicine outlet station is on the right side. The optimal combination is one medicine feeding station, three liquid preparation stations and one medicine outlet station.

[0061] Specifically, the medicine feeding station is mainly composed of medicine bottle tray feeding and conveying line, medicine bottle carrying module, intelligent liquid bag library, liquid bag robot, pre-labelling module and tool conveying module. It can adapt to 50ml-500ml infusion bags, support various specifications of medicine bottles such as 5-50ml syringe bottles and 1-30ml ampoule bottles, and can feed up to 48 sets of medicine bottle trays at a time. The medicine bottles and liquid bags of the same prescription are placed on the same tray, and the prescription information checking function can be selected. The whole equipment is light-proof, which can effectively protect the medicine. The carrying mechanism places the medicine bottles and liquid bags according to the prescription on the medicine tool, and the tool can be transferred to the corresponding liquid preparation station for liquid preparation operation according to the needs.

[0062] The liquid preparation station is mainly composed of ampoule liquid preparation robot, syringe liquid preparation module, syringe oscillation table, syringe carrying module, ampoule opening module, liquid bag carrying module, tool conveying module, weighing module and syringe conveying module. It is recommended that automatic liquid preparation equipment can meet most of the prescription requirements, and special prescriptions can be prepared by manual or offline special equipment. It can adapt to syringe bottles / ampoule bottles, can be mixed and matched, and can be made into a syringe liquid preparation special station or an ampoule liquid preparation special station according to the needs, with simplified structure, saving space and cost. The visual module is standard, the medicine bottle information is checked, the weighing table is checked to extract the liquid volume, the syringe or ampoule liquid preparation module is independent, the liquid preparation work can be carried out at the same time, the work efficiency is improved, the syringes are fed from the medicine outlet station and conveyed to the station by the syringe conveying module, the medicine tool is conveyed from the previous station to the liquid preparation station, the liquid bag is carried to the liquid preparation position by the tool carrying module, and the medicine tool flows to the next station after the liquid preparation is completed.

[0063] The medicine outlet station is mainly composed of liquid bag carrying module, label feeding module, tool circulating module and syringe feeding module. It can generate a two-dimensional code label in real time, which is convenient for tracing the liquid preparation information. The weighing module can be selected to check the liquid preparation dose. The syringe feeding module is matched to pull off the needle cap of the syringe, adjust the angle and put it into the syringe tool, which is transferred to the liquid preparation station. The same syringe is used for syringe and ampoule liquid preparation. The medicine tool is conveyed from the previous station to the medicine outlet station, the liquid bag is taken out by the medicine outlet robot, the label is pasted and then flows out of the equipment, and the tool is circulated by the tool circulating module and flows back to the medicine feeding station.

[0064] The main working mode is that the staff first starts the device, then installs the medicine tray and liquid bag syringe in the related device, and after the preparation work is completed, the medicine loading module in the medicine loading station takes out the tray, puts the ampoule and liquid bag into the medicine bottle tooling, and similarly, if there is a vial, the same processing is performed, then the tray is put back to the original place, and the liquid preparation module in the liquid preparation station starts to work. The information of the related medicine bottles is checked and automatically transported to the bottle opening module. Then the ampoule is automatically opened and the bottle is broken. The robot grabs the syringe to extract the liquid medicine. After the end, the syringe is disposed of in the collection box. Finally, the liquid bag is put into the discharge conveying line through the conveying module in the medicine discharging station. Finally, the label is automatically printed and attached. The liquid bag flows out of the device. The above is the complete process of the whole liquid preparation system.

[0065] Through the above structure, the staff determines the number of ampoules and vials of the medicine according to the prescription. After determining the number of medicine bottles, the tray 4 is rotated clockwise to 90°, so that the tray 4 is transferred from the inner wall of the basket frame 3 to the outer wall of the basket frame 3. After placing the medicine bottles, the reverse direction is reset counterclockwise. This method can avoid the situation that when there are too many medicines, the tray 4 is taken out one by one to place the medicine bottles and then the tray 4 is placed back on the basket frame 3. It saves time and effort, improves the comfort of the staff placing medicine bottles, and improves the efficiency of placing medicine bottles. It ensures the subsequent liquid preparation and use of medicines, and in the whole modular liquid preparation device, the auxiliary rotating assembly can improve the medicine loading efficiency of the medicine loading station module, which is convenient for the liquid preparation efficiency in the subsequent liquid preparation station module and the outflow of the medicine bottles in the medicine discharging station module.

[0066] As Figures 14 to 20 , Figure 23 and Figure 24As shown, the auxiliary rotating assembly comprises a resisting column 502 attached to the middle position of the reinforcing block 5, a rotating column 501 rotatably connected to the middle position of the reinforcing block 5, a hollow column 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 column 503, a stress platform 505 fixedly connected to the inner wall of the middle position of the reinforcing block 5, a weakening portion 506 provided at the end of the stress platform 505, a supporting bin 508 fixedly connected to the inner wall of the groove block of the flower basket frame 3, a clamping block 507 fixedly connected to the top of the reinforcing block 5, an adaptive pad 701 attached to the inner wall of the bearing ring 7, a placing ball 703 attached to the inner wall of the adaptive pad 701, a deformation pad 702 fixedly connected to the outer wall of the placing ball 703, the adaptive pad 701 is clamped to the outer wall of the flower basket frame 3 near the end 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 clamping groove is provided at the position of the placing ball 703 close to the tray 4, and the size of the clamping groove is matched with the size of the tray 4, the rotating column 501 penetrates through the middle position of the reinforcing block 5, the upper and lower ends of the rotating column 501 are fixedly connected to the middle position of the flower basket frame 3, the resisting column 502 is a solid body, the balance side plate 504 is symmetrically fixedly connected to the outer wall of the hollow column 503, the top of the clamping block 507 is attached to the inner wall of the groove block of the flower basket frame 3, the bottom of the supporting bin 508 is attached to the top of the rotating column 501, the top and bottom of the rotating column 501 are fixedly connected to the groove block of the flower basket frame 3, the reinforcing block 5 rotates on the rotating column 501, the resisting column 502, the hollow column 503, the balance side plate 504, the stress platform 505 and the weakening portion 506 are symmetrically distributed on the middle position of the side surface of the reinforcing block 5, and are divided into an upper part and a lower part, the distance between the resisting column 502, the hollow column 503 and the stress platform 505 is consistent with the thickness of the tray 4, the bottom of the clamping block 507 is fixedly connected to the top of the reinforcing block 5, and the bottom of the supporting bin 508 is attached to the top of the reinforcing block 5.

[0067] Through the above structure, in the initial state, the tray 4 is located on the inner wall of the basket frame 3, and the position of the basket frame 3 is consistent with the position of the tray 4, one end of the outer wall of the tray 4 is fitted in the groove strip on the side of the reinforcing block 5, and the abutting column 502, the balance side plate 504 and the stress platform 505 firmly fix the tray 4, the other end of the outer wall of the tray 4 is clamped and fitted on the clamping groove of the placing ball 703, and the clamping groove of the placing ball 703 is provided with a friction pad, under the action of the friction pad, the fixing capacity of the tray 4 is improved and the tray 4 will drive the movement of the placing ball 703 when it moves, the tray 4 will not slide horizontally at will under the above three structures, when it is needed to place the medicine bottle on the tray 4, the staff manually rotates the tray 4, the rotation direction is clockwise, in the process of rotation, the abutting column 502 and the stress platform 505 inside the groove strip of the reinforcing block 5 are the main fixing conditions, and the abutting column 502 and the stress platform 505 are hard materials, the rotation of the tray 4 will not cause its deformation, in the process of continuing to rotate the tray 4, the reinforcing block 5 and the tray 4 are deflected synchronously, and the placing ball 703 located at the opposite end of the tray 4 also rotates, the rotation center is the rotating column 501, the rotation process is manually rotated by the staff, and at this time there is also the liquid bag 6 on the tray 4, the height of the liquid bag 6 is consistent with the length of the slot opening on the basket frame 3, and will not block the rotation of the tray 4, such as Figure 23In order to rotate the tray 4 to a state of 45°, at this time only the liquid bag 6 is on the tray 4, and no medicine bottle, the entire load support of the tray 4 mainly relies on the contact of the end of the tray 4 with the abutting column 502, the hollow column 503, the stress platform 505 and the weakened part 506, and after rotation, the other end of the tray 4 is placed with the ball 703, and the inner wall of the bearing ring 7 is also separated, so that the tray 4 will appear to sink and tilt, and the sinking and tilting end is the end close to the ball 703, and the other end is the case of upward tilting, when the tray 4 is tilted, the end of the tray 4 will extrude and deform the stress platform 505 and the weakened part 506, especially the deformation and extrusion of the weakened part 506, and the effect of the deformed and extruded weakened part 506 in the middle position is greater than that on both sides, so that after the end of the tray 4 contacts the middle part of the weakened part 506, the lifting of both sides will increase the friction between the tray 4 and the weakened part 506, combined with the fact that at this time the tray 4 is in an invisible inclined state in the middle position of the groove of the reinforcing block 5, the lower hollow column 503 is on the outside and receives the maximum downward pressure value, and the upper weakened part 506 is on the innermost side and receives the maximum upward extrusion force value, in this state, the tray 4 cannot slide out of the groove of the reinforcing block 5, and in the case of sliding, the stress platform 505, the balance side plate 504 and the hollow column 503 in the upper part can all use the form of blocking to fix the position of the tray 4 in the groove of the reinforcing block 5, and the above-mentioned interval size formed between the abutting column 502, the hollow column 503 and the stress platform 505 is consistent with the thickness size of the tray 4, which further effectively avoids the tray 4 from sliding out of the groove of the reinforcing block 5, and after the tray 4 is rotated to the outside of the flower basket frame 3 (such as Figure 24), at this time, the tray 4 has been completely rotated from the inner wall position of the basket frame 3 to the outer wall position of the basket frame 3, and the rotated tray 4 is just fitted between the groove blocks of the basket frame 3, at this time, the support bin 508 fixed on the outer wall of the top of the rotating column 501 also successfully clamps the clamping block 507, which can further stabilize the tray 4 when placing the medicine bottles. Finally, start placing the medicine. During the placement process, the up and down and left and right shaking of the tray 4 will not affect the placement of the medicine bottles. After the placement is completed, rotate the tray 4 counterclockwise in the original return mode. When rotating back to the original position, the deformation pad 702 will contact the inner wall of the adaptive pad 701, and because the inner diameter of the adaptive pad 701 is smaller than the placement ball 703, the adaptive pad 701 will be directly squeezed when returning, so that the inner diameter of the adaptive pad 701 increases in the squeezed state. The increased diameter of the adaptive pad 701 is just capable of clamping the placement ball 703 inside the adaptive pad 701, and one end of the adaptive pad 701 is clamped on the outer wall of the basket frame 3, so that the adaptive pad 701 has a certain flexibility and cannot be in a fixed state. Thus, the adaptive pad 701 can better adapt to the placement ball 703. The function of the deformation pad 702 is that after the placement ball 703 is clamped into the adaptive pad 701, if the entire basket frame 3 shakes during transportation, in order to avoid the impact of the shaking of the entire basket frame 3 on the medicine bottles, the force generated by the shaking is fed back to the deformation pad 702, and the buffering effect can further reduce the shaking effect, thereby reducing the collision between the medicine bottles on the tray 4. It is worth mentioning that the way to take out the placement ball 703 from the adaptive pad 701 is to rotate the tray 4 with force, so that the outer wall of the placement ball 703 is squeezed on the outside of the adaptive pad 701, thereby increasing the diameter of the adaptive pad 701. After that, the placement ball 703 will come out under the action of the rotating force. The size and shape of the bearing ring 7 and the adaptive pad 701 will not completely wrap the placement ball 703, but will wrap most of it without squeezing deformation. This can improve stability while ensuring that the placement ball 703 can be normally clamped and taken out. Until it returns to the initial position, it is convenient and fast during the placement of the medicine bottles, and the staff does not need to carry the tray 4 up and down, which improves the subsequent liquid preparation progress. Compared with the previous carrying and placing of medicine bottles, the rotating method can save the staff's placement process of subsequent medicine bottles. When there are more prescription sheets or patients take medicine more frequently, the placement progress of the medicine bottles can be ensured, and the overall equipment size is moderate. The production and connection between parts are relatively simple, which will not cause production difficulties and time-consuming and labor-intensive.

[0068] It is worth mentioning that when the tray 4 is rotated back to the original position after the medicine bottle is placed, the medicine bottle on the tray 4 will not contact the right angle of the basket frame 3, and the diameter of the circle surrounded by the rotation track of the tray 4 is greater than half the length of the basket frame 3. It is particularly pointed out that 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 basket frame 3, the distance of half the length of the basket frame 3 as a diameter should be less than the distance from the rotating column 501 to the edge of the liquid bag 6 as a diameter, so that when the tray 4 is rotated to Figure 23 , the right angle of the tray 4 will not rub and contact with the medicine bottle on the tray 4, thereby avoiding the tray 4 from being unable to rotate normally and affecting the subsequent normal use.

[0069] As shown in Figures 14 to 16 , the middle position of the basket frame 3 is provided with a notch, the inner wall of the notch is provided with a connecting groove 302, the inner wall of the connecting groove 302 is fixedly connected with a buffer plate 301, the outer wall of the buffer plate 301 is fixedly connected with a connecting spring 303, the outer wall of the buffer plate 301 is fixedly connected with a friction pad 304, the buffer plate 301 is symmetrically distributed on the upper and lower and is in an arc shape, the top and bottom of the connecting spring 303 are fixedly distributed on the outer wall of the buffer plate 301, the buffer plate 301 and the connecting groove 302 are symmetrically distributed on the groove block of the basket frame 3, the connecting spring 303 is in a hollow shape, the buffer plate 301 is made of a hard material, the friction pad 304 is fixed on the buffer plate 301 and is distributed in two on the upper and lower, that is, a total of four, through the above structure, when the tray 4 is rotated to the outside of the basket frame 3, the outer wall of the tray 4 will contact the buffer plate 301, and the extended outer end of the buffer plate 301 is bent to the two sides, the tray 4 is easily entered into the buffer plate 301 when rotating, without deliberately adjusting the position to enter, and the distance between the upper and lower buffer plates 301 is slightly smaller than the thickness size of the tray 4, after the tray 4 enters the buffer plate 301, the thickness of the tray 4 will support the upper and lower buffer plates 301, and the buffer plates 301 will drive the connecting spring 303 to be straightened in the upward and downward directions, and when the tray 4 enters the buffer plate 301, the friction pad 304 will further limit the movement of the tray 4, under the condition of limiting the movement, the tray 4 begins to reduce the speed when rotating to contact the buffer plate 301, which relieves the impact on the outer wall groove block of the basket frame 3 after rotating a circle due to the too fast speed of the staff rotating the tray 4, avoids the damage to the basket frame 3 and the tray 4, and also avoids the damage to the reinforcing block 5, thereby ensuring the stable state between the parts.

[0070] The application also provides a liquid preparation method of the modular liquid preparation device.

[0071] Step one, manual operation: start the equipment and load the medicine tray, liquid bag and syringe into the related equipment.

[0072] Step two, medicine station: the tray is placed in the pulling mechanism, the liquid bag is placed in the medicine tool by the carrying module, then the medicine is placed in the medicine tool by the carrying module, and finally the tray is placed back by the pulling mechanism;

[0073] Step three, liquid preparation station: automatically review the medicine bottle information and carry to the bottle opening module, ampoule automatic bottle opening and bottle breaking, vial automatic cap opening, robot liquid extraction, liquid preparation module injects liquid into the liquid bag, and weighs and judges;

[0074] Step four, medicine outlet station: the liquid bag is taken by the carrying module and placed in the discharge conveying line, the label is automatically printed and pasted, and finally the liquid bag flows out of the equipment.

[0075] The working principle of the technical scheme provided by the application is as follows:

[0076] In the initial state, the tray 4 is located on the inner wall of the basket frame 3, and the position of the basket frame 3 is consistent with the position of the tray 4, one end of the outer wall of the tray 4 is fitted in the groove of the reinforcing block 5, and the abutting column 502, the balance side plate 504 and the stress platform 505 firmly fix the tray 4, the other end of the outer wall of the tray 4 is clamped and fitted in the clamping groove of the placing ball 703, and the clamping groove of the placing ball 703 is provided with a friction pad, under the action of the friction pad, the fixing capacity of the tray 4 is improved and the tray 4 will drive the movement of the placing ball 703 when moving, the tray 4 will not slide horizontally at will under the above three structures, when it is needed to place the medicine bottle on the tray 4, the staff manually rotates the tray 4, the rotation direction is clockwise, in the process of rotation, the abutting column 502 and the stress platform 505 in the groove of the reinforcing block 5 are the main fixing conditions, and the abutting column 502 and the stress platform 505 are hard materials, the rotation of the tray 4 will not cause deformation, in the process of continuing to rotate the tray 4, the reinforcing block 5 and the tray 4 are deflected synchronously, and the placing ball 703 at the opposite end of the tray 4 also rotates, the rotation center is the rotating column 501, the rotation process is manually rotated by the staff, and at this time, the tray 4 also has the existence of the liquid bag 6, and the height of the liquid bag 6 is consistent with the length of the slot opening in the basket frame 3, and will not block the rotation of the tray 4, such as Figure 23In order to rotate the tray 4 to a state of 45°, at this time only the liquid bag 6 is on the tray 4, and no medicine bottle, the entire load support of the tray 4 mainly relies on the contact of the end of the tray 4 with the abutting column 502, the hollow column 503, the stress platform 505 and the weakened part 506, and after rotation, the other end of the tray 4 is placed with the ball 703, and the inner wall of the bearing ring 7 is also separated, so that the tray 4 will appear to sink and tilt, and the sinking and tilting end is the end close to the ball 703, and the other end is the case of upward tilting, when the tray 4 is tilted, the end of the tray 4 will extrude and deform the stress platform 505 and the weakened part 506, especially the deformation and extrusion of the weakened part 506, and the effect of the deformed and extruded weakened part 506 in the middle position is greater than that on both sides, so that after the end of the tray 4 contacts the middle part of the weakened part 506, the lifting of both sides will increase the friction between the tray 4 and the weakened part 506, combined with the fact that at this time the tray 4 is in an invisible inclined state in the middle position of the groove of the reinforcing block 5, the lower hollow column 503 is on the outside and receives the maximum downward pressure value, and the upper weakened part 506 is on the innermost side and receives the maximum upward extrusion force value, in this state, the tray 4 cannot slide out of the groove of the reinforcing block 5, and in the case of sliding, the stress platform 505, the balance side plate 504 and the hollow column 503 in the upper part can all use the form of blocking to fix the position of the tray 4 in the groove of the reinforcing block 5, and the above-mentioned interval size formed between the abutting column 502, the hollow column 503 and the stress platform 505 is consistent with the thickness size of the tray 4, which further effectively avoids the tray 4 from sliding out of the groove of the reinforcing block 5, and after the tray 4 is rotated to the outside of the flower basket frame 3 (such as Figure 24), at this time, the tray 4 has been completely rotated from the inner wall position of the basket frame 3 to the outer wall position of the basket frame 3, and the rotated tray 4 is just fitted between the groove blocks of the basket frame 3, at this time, the support bin 508 fixed on the outer wall of the top of the rotating column 501 also successfully clamps the clamping block 507, which can further stabilize the tray 4 when placing the medicine bottles. Finally, start placing the medicine. During the placement process, the up and down and left and right shaking of the tray 4 will not affect the placement of the medicine bottles. After the placement is completed, rotate the tray 4 counterclockwise in the original way, and when rotating back to the original position, the deformation pad 702 will contact the inner wall of the adaptive pad 701, and because the inner diameter of the adaptive pad 701 is smaller than the placement ball 703, the adaptive pad 701 will be directly squeezed when returning, so that the inner diameter of the adaptive pad 701 increases in the squeezed state. The increased diameter of the adaptive pad 701 is just capable of clamping the placement ball 703 inside the adaptive pad 701, and one end of the adaptive pad 701 is clamped on the outer wall of the basket frame 3, so that the adaptive pad 701 has a certain flexibility and cannot be in a fixed state. Thus, the adaptive pad 701 can better adapt to the placement ball 703. The function of the deformation pad 702 is that after the placement ball 703 is clamped into the adaptive pad 701, if the entire basket frame 3 shakes during transportation, in order to avoid the impact of the shaking of the entire basket frame 3 on the medicine bottles, the force generated by the shaking is fed back to the deformation pad 702, and the buffering effect can further reduce the shaking effect, thereby reducing the collision between the medicine bottles on the tray 4. It is worth mentioning that the way to take out the placement ball 703 from the adaptive pad 701 is to rotate the tray 4 with force, so that the outer wall of the placement ball 703 is squeezed on the outside of the adaptive pad 701, thereby increasing the diameter of the adaptive pad 701. After that, the placement ball 703 will come out under the action of the rotating force. The size and shape of the bearing ring 7 and the adaptive pad 701 will not completely wrap the placement ball 703, but will wrap most of it without squeezing deformation. This can improve stability while ensuring that the placement ball 703 can be normally clamped and taken out. Until it returns to the initial position, it is convenient and fast during the placement of the medicine bottles, and the staff does not need to carry the tray 4 up and down, which improves the progress of subsequent liquid preparation. Compared with the previous carrying and placing of medicine bottles, the rotating method can save the staff's placement process of subsequent medicine bottles. When there are more prescription sheets or patients take medicine more frequently, the progress of placing medicine bottles can be ensured, and the overall equipment size is moderate. The production and connection between parts are relatively simple, which will not cause production difficulties and time-consuming and labor-intensive.

[0077] It is worth mentioning that when the tray 4 is rotated back to the original position after the medicine bottles are placed, the medicine bottles on the tray 4 will not contact the right angle of the basket frame 3, and the diameter of the circle surrounded by the rotation track of the tray 4 is greater than half the length of the basket frame 3. It is particularly pointed out that since the center of the rotation of the tray 4 is the rotating column 501, which is located at the center of the length of the basket frame 3, the distance of half the length of the basket frame 3 as a diameter should be less than the distance from the rotating column 501 to the edge of the liquid bag 6 as a diameter, so that when the tray 4 is rotated to Figure 23 , the right angle of the tray 4 will not rub and contact the medicine bottles on the tray 4, thereby avoiding the tray 4 from being unable to rotate normally and affecting the subsequent normal use.

[0078] When the tray 4 is rotated to the outside of the 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 is curved to both sides, the tray 4 can easily enter the buffer plate 301 when rotating without deliberately adjusting the position to enter. In addition, 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, the thickness of the tray 4 will prop up the upper and lower buffer plates 301, and the propped-up buffer plates 301 will drive the connecting spring 303 to be straightened in the upward and downward directions. When the tray 4 enters the buffer plate 301, the friction pad 304 will further limit the movement of the tray 4. Under the condition of limiting the movement, the tray 4 will start to slow down when it rotates to contact the buffer plate 301, thereby relieving the impact on the outer wall groove block of the basket frame 3 after rotating a full circle due to the excessive speed of the staff rotating the tray 4, avoiding damage to the basket frame 3 and the tray 4, and also avoiding damage to the reinforcing block 5, thereby ensuring the stable state between the various components.
