[0022] See also Figures 1 to 7 The embodiment of the present invention provides a drawer-type injection dispensing mechanism, comprising a drawer body 1, two drawer rails 2 installed in the medicine adding port of the automatic medicine dispensing device and respectively located on both sides of the drawer body 1, and a plurality of storage and dispensing small drawers 3 installed side by side in the drawer body 1, and the drawer body 1 can slide along the two drawer rails 2 to open or close the drawer body 1. A plurality of first medicine outlets 101 are arranged side by side at the bottom end of the drawer body 1. A dispensing conveyor belt 4 and a conveyor belt driving assembly 5 for driving the dispensing conveyor belt 4 to rotate are installed between the two side plates of the storage and dispensing small drawer 3, and a plurality of medicine storage slots 601 for storing injection medicines are evenly arranged on the outer surface of the dispensing conveyor belt 4 in the circumferential direction, and a second medicine outlet 301 is arranged at the bottom end of the storage and dispensing small drawer 3, and the end of the dispensing conveyor belt 4 is located above the second medicine outlet 301, and the second medicine outlet 301 corresponds to the position of the first medicine outlet 101 one by one.

[0023] When adding medicine, the medicine adding drawer is opened, and then the medicine adding personnel place the injection medicine in the medicine storage slot 601 located on the upper part of the dispensing conveyor belt 4 inside each storage and dispensing small drawer 3, and one bottle of injection medicine is placed horizontally in one medicine storage slot 601. After adding medicine, the drawer body 1 is closed. Among them, the size of the medicine storage slot 601 of each storage and dispensing small drawer 3 can be freely customized according to the size of the injection medicine, so that a drawer-type injection dispensing mechanism can simultaneously distribute injection medicines of multiple different sizes, thereby enhancing the flexibility and applicability of the mechanism.

[0024] When dispensing medicine, the conveyor drive assembly 5 drives the distribution conveyor 4 to rotate, and the injectable medicines in the medicine storage tank 601 located at the upper end of the distribution conveyor 4 rotate downward with the distribution conveyor 4 until they fall from the corresponding second medicine outlet 301 and the first medicine outlet 101 in sequence under the action of gravity onto the medicine dispensing conveyor belt of the automatic medicine dispensing equipment, and then are transported to the medicine outlet through the medicine dispensing conveyor belt.

[0025] The above-mentioned drawer-type injection dispensing mechanism realizes the storage and automatic distribution of one or more injection medicines by arranging multiple storage and distribution small drawers 3 in the drawer body 1, and cooperating with the distribution conveyor belt 4 and the conveyor belt driving assembly 5 arranged in the storage and distribution small drawer 3, thereby solving the shortcomings of the existing automatic medicine dispensing machines in the distribution of injection medicines, expanding the application scope of the automatic medicine dispensing machines, and enabling them to more comprehensively meet the needs of hospital pharmacies; by installing multiple storage and distribution small drawers 3 side by side, the space in the drawer body 1 is effectively utilized, so that the mechanism can store more medicines in a limited volume, saving space resources in the pharmacy; the overall structure is compact, which is not only convenient for installation and maintenance, but also convenient for integration in automatic medicine dispensing equipment, and will not occupy too much internal space of the equipment.

[0026] See also Figure 6 In one embodiment, the outer surface of the dispensing conveyor belt 4 is covered with a medicine storage sponge 6 and bonded and fixed to the medicine storage sponge 6, and a plurality of medicine storage slots 601 are evenly arranged on the outer surface of the medicine storage sponge 6 in the circumferential direction. The softness and elasticity of the medicine storage sponge 6 can effectively protect the injection medicine, reduce the collision and friction of the injection medicine during the transmission process, and prevent the injection medicine from being damaged or the label from being worn. The bonding and fixing of the medicine storage sponge 6 to the dispensing conveyor belt 4 ensures the stability of the medicine storage slot 601 during the transmission process, and reduces the risk of the injection medicine slipping or falling out during the movement.

[0027] See also Figure 6 In one embodiment, the medicine storage slot 601 is U-shaped. The setting of the U-shaped slot forms a certain barrier on both sides of the injection medicine, effectively preventing the injection medicine from falling out of the slot during the rotation of the distribution conveyor belt 4, improving the reliability of distribution, and ensuring that when the medicine storage slot 601 rotates downward driven by the rotation of the distribution conveyor belt 4, the injection medicine in the medicine storage slot 601 can fall smoothly under the action of gravity. In addition, the setting of the U-shaped slot can also be arranged more compactly on the distribution conveyor belt 4, so as to accommodate more medicines in a limited space, thereby improving space utilization.

[0028] See also Figure 5 , Figure 6In one embodiment, the conveyor belt drive assembly 5 includes a drive motor 501, a transmission gear 502, a driving shaft 503 and a driven shaft 504. The drive motor 501 is fixed on one of the side panels of the storage and distribution small drawer 3 and is located inside the distribution conveyor belt 4. The driving shaft 503 and the driven shaft 504 are movably installed between the two side panels of the storage and distribution small drawer 3 through a bearing seat 505. The drive motor 501 is connected to the driving shaft 503 through a transmission gear 502. The distribution conveyor belt 4 is sleeved on the driving shaft 503 and the driven shaft 504 to form a closed-loop transmission path, so that the distribution conveyor belt 4 can run smoothly and continuously. The conveyor belt drive assembly 5 set up as above has a very compact structure and makes full use of the internal space of the storage and distribution small drawer 3 to improve space utilization and system integration. In addition, the setting of the bearing seat 505 not only adjusts the tension of the distribution conveyor belt 4, but also facilitates the disassembly and assembly of the driving shaft 503 and the driven shaft 504.

[0029] See also Figure 4 , Figure 5 In one embodiment, a pair of through-beam sensors 7 for counting are arranged outside the two side panels of the storage and distribution small drawer 3, one of which is a transmitter and the other is a receiver. A first sensing avoidance opening 302 is opened on the two side panels of the storage and distribution small drawer 3 at the position corresponding to the through-beam sensor 7. The first sensing avoidance opening 302 allows the light emitted by the transmitter to pass through and reach the receiver, so as to ensure that the through-beam sensor 7 can accurately detect the passage of the medicine storage slot 601 without affecting the normal operation of the distribution conveyor belt 4. As the distribution conveyor belt 4 rotates, the medicine storage slot 601 located at the lower part of the conveyor belt will pass through the detection area of ​​the through-beam sensor 7 in sequence. When the medicine storage slot 601 blocks the light of the transmitter, the through-beam sensor 7 will output a trigger signal, indicating that a medicine storage slot 601 has passed through the detection area. By recording the number and time interval of these trigger signals, the position and number of the medicine storage slots 601 on the distribution conveyor belt 4 can be accurately calculated, thereby realizing accurate control of the drug distribution process.

[0030] Specifically, the through-beam sensor 7 is fixed to the side panel of the storage and distribution small drawer 3 through the sensor bracket 8. Since the through-beam sensor 7 is installed outside the storage and distribution small drawer 3, it is relatively easy to access and maintain. If it is necessary to replace or upgrade the sensor, it only needs to be simply disassembled and reinstalled, without large-scale disassembly and reorganization of the entire distribution system. In addition, it is fixed to the side panel of the storage and distribution small drawer 3, does not occupy the internal space of the storage and distribution small drawer 3, and can make the structure of the storage and distribution small drawer 3 more compact.

[0031] See also Figures 3 to 5In one embodiment, a medicine drop sensor 9 is provided at one side of the inner end of the drawer body 1, and a second sensing avoidance opening 303 is provided on the two side panels of the storage and distribution small drawer 3 at the position corresponding to the medicine drop sensor 9. The second sensing avoidance opening 303 ensures that the medicine drop sensor 9 is not blocked by the side panels of the storage and distribution small drawer 3, and is ready to accurately detect the injection medicine dropped from each storage and distribution small drawer 3, thereby ensuring the accuracy and timeliness of the distribution process.

[0032] See also Figure 1 , Figure 5 , Figure 7 In one embodiment, a small drawer cover 10 that can slide back and forth is provided at the top opening of the small storage and distribution drawer 3 to open or close the small storage and distribution drawer 3. The setting of the small drawer cover 10 can effectively prevent dust, moisture or other contaminants from entering the inside of the drawer when the small storage and distribution drawer 3 is closed, and reduce the occurrence of misoperation to a certain extent, thereby improving the safety of the drawer. Since the cover needs to slide to open the drawer, the person adding medicine will be more cautious when operating to avoid adding the wrong medicine, spilling or damaging the medicine due to carelessness. The sliding setting of the small drawer cover 10 makes it easier and faster to open and close the drawer. The person adding medicine only needs to simply slide the cover to complete the operation without having to lift or close the entire drawer laboriously, thereby improving work efficiency and convenience of operation.

[0033] Specifically, both sides of the top opening of the storage and distribution small drawer 3 are provided with limit strips 304 that limit the small drawer cover 10 from sliding forward and backward, so as to prevent the small drawer cover 10 from shaking left and right when sliding forward and backward. A first lock buckle 11 is provided at the top end of the small drawer cover 10, and an electromagnetic lock fixing plate 12 is provided at the top end of the storage and distribution small drawer 3. The end of the electromagnetic lock fixing plate 12 is provided with a first electromagnetic lock 13 that matches the first lock buckle 11 at the position corresponding to each storage and distribution small drawer 3. By controlling the power on and off state of the first electromagnetic lock 13, the system can accurately unlock the small drawer cover 10 of each storage and distribution small drawer 3 when adding medicine, so as to prevent the medicine adding personnel from putting the wrong medicine storage tank 601 when adding medicine. When the small drawer cover 10 slides to the closed position, the first lock buckle 11 can cooperate with the corresponding first electromagnetic lock 13 to firmly lock the small drawer cover 10 in the closed state, ensuring that the small drawer cover 10 will not be accidentally opened due to vibration or bumps during the pulling process, and can also effectively prevent unauthorized personnel from arbitrarily accessing the interior of the drawer, thereby enhancing the safety of the drawer.

[0034] In addition, the top of the first lock buckle 11 is higher than the electromagnetic lock fixing plate 12, and a pulley 14 is provided on one side of the top of the first lock buckle 11, and the pulley 14 cooperates with the linear slide rail provided at the medicine adding port of the automatic medicine dispensing device to further limit the forward and backward sliding of the small drawer cover 10. By designing the top of the first lock buckle 11 to be higher than the electromagnetic lock fixing plate 12, this design cleverly utilizes the spatial position relationship to enhance the stability and accuracy of the forward and backward sliding of the small drawer cover 10. When the small drawer cover 10 is in a closed state, the first lock buckle 11 not only cooperates with the first electromagnetic lock 13 to achieve locking, but its higher position can also provide a certain support force for the small drawer cover 10 through the cooperation of the pulley 14 and the linear slide rail, reduce the friction and resistance during the sliding process, and prevent the problem of the end being suspended in the air and tilting up and down or shaking during the forward and backward sliding process.

[0035] See also Figure 7 In one embodiment, a pull-out hole 1001 is provided at the front end of the small drawer cover 10. The pull-out hole 1001 provides an intuitive and easy-to-operate handle position for the medication adding personnel. The medication adding personnel can easily slide the small drawer cover 10 forward and backward through the pull-out hole 1001 to open or close the storage and dispensing small drawer 3 without having to find other difficult-to-identify operation points.

[0036] In one embodiment, the small drawer cover 10 is made of a transparent material. The transparent small drawer cover 10 allows the user to directly observe the amount, state, or abnormality of the injection medicines stored in the small drawer 3 without opening the small drawer cover 10 frequently.

[0037] See also Figure 1 , Figure 2 In one embodiment, a second electromagnetic lock 15 is provided at the end of the side panel of the drawer body 1, and the second electromagnetic lock 15 cooperates with a second lock buckle provided at the medicine adding port of the automatic medicine dispensing device to lock the drawer body 1. The provision of the second electromagnetic lock 15 can effectively prevent unauthorized personnel from accessing the interior of the drawer at will, enhance the safety of the drawer, and help enhance the stability of the drawer body 1 in the automatic medicine dispensing device. When the drawer body 1 is locked, the magnetic force generated by the second electromagnetic lock 15 can ensure that the drawer body 1 will not accidentally slide out or loosen during the movement or vibration of the dispensing conveyor belt 4, thereby ensuring the normal operation of the equipment and the safe dispensing of medicines.

[0038] See also Figure 1 In one embodiment, a dosing indicator light 16 is provided at the front end of the drawer body 1 corresponding to each storage and distribution small drawer 3. The dosing indicator light 16 can intuitively display the dosing status of each storage and distribution small drawer 3. When a storage and distribution small drawer 3 needs to be dosed, the corresponding indicator light will light up to remind the staff to add medicine in time.
