Description

Technical Field

[0001] This application relates to the field of smart medicine cabinets, and more particularly to a medicine storage box and a smart storage cabinet. Background Technology

[0002] Currently, hospitals and large pharmaceutical factories often involve the storage and retrieval of numerous and diverse medications and medical consumables. Different departments and wards require different medications, and each department has a separate medicine cabinet containing varying quantities and types of drugs. The type and quantity of each medication in these cabinets must be manually recorded. When a medication is out of stock, the doctor retrieves the missing medication from the main warehouse and updates the record accordingly. However, manual recording of medication information is prone to omissions and forgetfulness, requires a high degree of meticulousness from the record-keeper, and is inconvenient for medication management. Summary of the Invention

[0003] To facilitate drug management and reduce errors and omissions caused by manual recording, this application provides a drug storage box and an intelligent storage cabinet.

[0004] Firstly, this application provides a medicine storage box, which adopts the following technical solution:

[0005] A medicine storage box for placement in a medicine cabinet, comprising:

[0006] The box body is used to hold medicines inside, and has a medicine dispensing opening on the upper side, with a medicine dispensing door installed at the medicine dispensing opening; one end of the box body has a medicine retrieval opening, with a medicine retrieval door installed at the medicine retrieval opening;

[0007] A scanning device is installed inside the placement box body and located at one end of the placement box body. The scanning device faces the other end of the placement box body and is used to scan the information of the medicine put into the placement box body from the medicine dispensing port.

[0008] A display device is used to display information about the medicine placed inside the placement box body;

[0009] A controller, connected between the scanning device and the display device, is used to receive drug information scanned by the scanning device and transmit the acquired drug information to the display device;

[0010] A locking component is disposed between the placement box body and the medicine dispensing door, for fixing the medicine dispensing door to the placement box body or releasing the connection between the medicine dispensing door and the placement box body.

[0011] By adopting the above technical solution, when placing medicines, each type of medicine can be placed in the same storage box. When placing medicines in the storage box, the barcode of the medicine should face the scanning device. The scanning device will scan the medicine information to obtain the medicine type information. As more medicines are placed, the scanning device scans more frequently. The controller can count the number of scans to determine the quantity of medicines in each storage box, thus achieving automatic statistics on medicine type and quantity. The obtained medicine type and quantity information will also be transmitted by the controller to the display device for display, eliminating the need for manual recording. This makes medicine management more convenient, and because the medicine information is automatically acquired, it greatly reduces errors and omissions caused by manual recording.

[0012] Optionally, a push plate is slidably connected inside the placement box body, and a pushing device is provided between the push plate and the end of the placement box body away from the medicine dispensing port to push the push plate toward the medicine dispensing port. The pushing device is configured to stop when the side of the push plate away from the pushing device is subjected to a resisting force.

[0013] By adopting the above technical solution, under normal circumstances, the pushing device can drive the push plate towards the dispensing port until the push plate abuts against the medicine, causing the push plate to be subjected to a resisting force, at which point the pushing device stops. When the doctor takes the medicine from the dispensing port, the resisting force applied to the push plate disappears, and the pushing device continues to drive the push plate towards the dispensing port until the push plate abuts against the medicine again, and the medicine applies a resisting force to the push plate, at which point the pushing device stops. This cycle is repeated, ensuring that the medicine is always pushed to a position close to the dispensing port for easy dispensing.

[0014] Optionally, a first contact switch is installed on the side of the push plate away from the pushing device. The first contact switch is connected to the pushing device, and the pushing device stops when the first contact switch is pressed.

[0015] By adopting the above technical solution, when the pushing device pushes the push plate against the medicine, the medicine will be pressed against the first contact switch, and the first contact switch controls the pushing device to stop.

[0016] Optionally, the pushing device includes a linear motor fixed to the side wall of the placement box body, and the push plate is fixed to the slider of the linear motor.

[0017] By adopting the above technical solution, a linear motor can drive the push plate to move linearly.

[0018] Optionally, the pushing device is equipped with a first linear displacement sensor for detecting the movement of the push plate. The slider of the first linear displacement sensor is fixed to the push plate. The first linear displacement sensor is connected to the controller, and the controller determines the amount of medicine to be taken each time based on the data detected by the first linear displacement sensor.

[0019] By adopting the above technical solution, since the distance between the dispensing port and the pushing device is a fixed value, when the first linear displacement sensor detects the length of the distance between the push plate and the first electric push rod, the distance between the dispensing port and the push plate will be calculated. By summing the total length with the number of medicines, the length occupied by each box of medicine can be determined. When the first electric push rod pushes the push plate a certain distance, the quantity of medicine dispensed each time can be determined by the distance moved and the length occupied by each box of medicine.

[0020] Secondly, this application provides an intelligent storage cabinet, which adopts the following technical solution:

[0021] A smart storage cabinet includes a cabinet body and a medicine storage box detachably connected to the cabinet body. The cabinet body has multiple slots on one side for inserting the medicine storage box. The cabinet body is provided with a fixing device to fix the position of the medicine storage box in the slots. When the medicine storage box is placed in the slot, the cabinet body can obtain the medicine information in the medicine storage box.

[0022] By adopting the above technical solution, the medicine storage box can be fixed in the slot by the fixing device, and the cabinet can also obtain the medicine information in the medicine storage box in the slot at each position, thereby obtaining the medicine information placed at each position, which makes medicine management more convenient.

[0023] Optionally, the fixing device is located on one side of the slot and includes a fixing block slidably connected inside the cabinet and a second electric push rod that drives the fixing block to slide in the direction of the slot. The medicine storage box body has a fixing groove on the side facing the fixing device for the fixing block to be inserted.

[0024] By adopting the above technical solution, when the medicine box is inserted into the slot, the second electric push rod is operated to drive the fixing block to slide in the direction of the slot, so that the fixing block is inserted into the fixing groove, thereby fixing the position of the medicine box in the slot.

[0025] Optionally, a manual unlocking device is provided between the push rod of the second electric push rod and the fixed block. The manual unlocking device includes a first threaded rod fixed to the push rod of the second electric push rod, a second threaded rod fixed to the side of the fixed block facing the second electric push rod, and a threaded cylinder located between the first threaded rod and the second threaded rod and threadedly connected to both the first threaded rod and the second threaded rod. The thread direction on the first threaded rod is opposite to the thread direction on the second threaded rod.

[0026] By adopting the above technical solution, when the second electric push rod malfunctions, the threaded cylinder can be rotated manually, so that the first threaded rod and the second threaded rod are relatively close inside the threaded cylinder, thereby driving the fixing block to slide out of the fixing groove and releasing the fixation of the medicine placement box.

[0027] Optionally, the manual unlocking device further includes a screwing assembly with one end exposed to the outside for operation and the other end connected to the threaded cylinder to drive the threaded cylinder to rotate. The screwing assembly includes a rotating rod rotatably connected to the cabinet, a driving bevel gear slidably connected to the threaded cylinder, and a driven bevel gear fixed to the threaded cylinder. The driving bevel gear rotates synchronously with the threaded cylinder and meshes with the driven bevel gear. The end of the rotating rod away from the threaded cylinder is flush with the outer wall of the cabinet. The end of the rotating rod away from the threaded cylinder has a rotating groove for external rotating tools to be inserted.

[0028] By adopting the above technical solution, staff can directly operate an external rotating tool to insert into the rotating groove and operate the external tool to drive the rotating rod to rotate. The active bevel gear will also drive the threaded cylinder to rotate through the driven bevel gear, so that staff can unlock the medicine storage box from the outside.

[0029] Optionally, the second electric push rod is slidably connected inside the cabinet. A limit plate is fixed inside the cabinet, located on the side of the second electric push rod away from the manual unlocking device. A retaining spring is fixed between the second electric push rod and the limit plate. Several first teeth with right-angled triangular cross-sections are fixed on the lower surface of the second electric push rod. Several second teeth that mesh with the first teeth are fixed at the position where the second electric push rod is installed inside the cabinet. The first teeth and the second teeth restrict the second electric push rod to move only in a direction away from the manual unlocking device.

[0030] By adopting the above technical solution, when the ends of the first threaded rod and the second bolt rod abut against each other and manual unlocking is required, the operator can rotate the rotating rod in the opposite direction to make the first threaded rod and the second threaded rod move away from each other. At this time, the second electric push rod will squeeze the abutment spring and move it away from the medicine storage box. At this time, the first tooth also slides on the second tooth. Then the operator rotates the rotating rod in the forward direction. Due to the engagement of the first tooth and the second tooth, the first threaded cylinder and the second threaded cylinder are relatively close, which will drive the fixing block to slide out of the fixing groove, thereby unlocking.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] This application sets up a medicine storage box and installs a scanning device, which can automatically identify the information of the medicines placed in the medicine storage box through the scanning device and record the information of the medicines in the medicine storage box through the controller. This realizes automatic statistics and recording of medicines, which makes medicine management more convenient. Moreover, the entire operation process does not require manual recording and statistics. Staff only need to place each type of medicine in each medicine storage box, which greatly reduces the errors caused by manual recording and the situation of omissions and forgetting.

[0033] The first linear displacement sensor allows for the tracking of the distance the pusher moves each time. Based on the length occupied by each box of medicine, the number of medicines taken out each time can be determined, making the tracking more accurate.

[0034] The intelligent storage cabinet enables the storage and data collection of various medicines. The unlocking device allows for automatic unlocking under normal conditions, as well as manual unlocking in case of malfunction, making operation more convenient and flexible.

[0044] The following is in conjunction with the appendix Figure 1 - 8 provides further detailed description of this application.

[0045] This application discloses a medicine storage box. (Refer to...) Figure 1 and Figure 2 The medicine storage box is used to place medicines in a medicine cabinet. It includes a storage box body 1, which is a hollow box with the hollow interior used to store medicines.

[0046] A medicine dispensing opening 11 is provided on the upper side of the placement box body 1, allowing staff to easily place medicines into the placement box body 1 from above. A medicine dispensing door 12 is hinged to the medicine dispensing opening 11, which can be closed to prevent external impurities from entering the placement box body 1 when no medicine is being placed. A medicine retrieval opening 13 is provided at one end of the placement box body 1. In use, the placement box body 1 can be directly installed in a medicine cabinet, and staff can directly retrieve the medicine from the medicine retrieval opening 13 at one end of the placement box body 1, making medicine retrieval more convenient.

[0047] Reference Figure 2 A dispensing door 14 is hinged to the dispensing port 13, which closes the dispensing port 13. A locking component 2 is provided between the dispensing door 14 and the placement box body 1 to fix the relative position between the dispensing door 14 and the placement box body 1, preventing unauthorized removal of medicines. When medicines need to be taken, the locking component 2 is unlocked to open the dispensing door 14 and retrieve the medicine.

[0048] A scanning device 15 is installed inside the placement box body 1. The scanning device 15 is used to identify the information of the medicine placed through the medicine dispensing port 11. The scanning device 15 is installed at the end of the placement box body 1 away from the medicine dispensing door 14, and is positioned near the upper end of the placement box body 1 with the scanning end of the scanning device 15 facing the medicine dispensing port 13. When the medicine is placed inside the placement box body 1, the scanning device 15 is positioned above the medicine. When the medicine is placed inside the placement box body 1, the scanning device 15 can scan the barcode of the medicine box to identify the medicine information. When a new medicine is placed inside the placement box body 1, the medicine already in the placement box body 1 will not obstruct the scanning device 15.

[0049] A controller connected to the scanning device 15 is also provided. The controller can be a PLC controller. The controller can acquire the drug information scanned by the scanning device 15. The controller can be a controller with a counting function, or a controller without a counting function with a counter connected to it. When multiple boxes of drugs are continuously placed into the placement box body 1, the scanning device 15 will scan multiple times. The controller will count the number of scans by the scanning device 15 to determine the number of drugs placed.

[0050] The controller is connected to a display device 16. When the controller obtains the scanning information from the scanning device 15, it transmits the obtained information such as the type and quantity of medicines to the display device 16 for display.

[0051] The display device 16 can be a mobile phone, computer, screen, etc., and the controller can be connected to the display device 16 via wired or wireless means. In this application, the display device 16 is a display screen installed on the medicine dispensing door 14, and the controller can be installed on the back of the display screen and connected to the display screen via a wire. This allows the display screen to be exposed to the outside for easy viewing by the doctor after the medicine box is placed on the medicine cabinet.

[0052] The scanning device 15 can be a barcode scanner, which can scan the barcode and QR code information on the medicine to obtain the medicine information. Alternatively, the scanning device 15 can be a card reader, which reads the RFID electronic tag information affixed to the medicine to obtain the medicine information. This application uses a barcode scanner as an example for illustration.

[0053] Reference Figure 2 To facilitate doctors in obtaining medication, a push plate 17 is slidably connected inside the placement box body 1 to push the medication to the dispensing port 13. A pushing device 3 is provided between the push plate 17 and the end of the placement box body 1 away from the dispensing port 13 to drive the push plate 17 toward the dispensing port 13. The pushing device 3 is configured to automatically stop when the side of the push plate 17 away from the pushing device 3 is subjected to a resisting force.

[0054] Specifically, the pushing device 3 includes a first electric push rod 31 fixedly connected to the end of the placement box body 1 away from the dispensing port 13, and a push plate 17 fixedly connected to the push rod of the first electric push rod 31. A first contact switch 171 is fixedly connected to the side of the push plate 17 away from the pushing device 3. The first contact switch 171 is connected to the pushing device 3 to control the pushing device 3 to stop. When the medicine is placed in the placement box body 1, the pushing device 3 is activated. The pushing device 3 will drive the push plate 17 to move towards the dispensing port 13. The push plate 17 also pushes the medicine box dispensing port 13 until the medicine comes into contact with the placement box body 1 at the dispensing port 13. As the push plate 17 continues to move, the medicine also provides a resisting force to the first contact switch 171, causing the first contact switch 171 to close. The first contact switch 171 also controls the pushing device 3 to stop. This ensures that all medicines are located close to the dispensing port 13, making it easier to retrieve the medicine. When the medicine is taken again, the resistance force exerted on the first contact switch 171 by the medicine disappears, the first contact switch 171 is disconnected, and the pushing device 3 pushes the medicine again toward the direction of the medicine dispensing port 13, so that all medicines can be automatically pushed to a position close to the medicine dispensing port 13.

[0055] To automatically count the amount of medicine dispensed each time, a linear displacement sensor 32 is fixedly connected to the main body of the first electric push rod 31. The main body of the linear displacement sensor 32 is fixed to the main body of the first electric push rod 31 or to the placement box body 1. The slider of the linear displacement sensor 32 is fixed to the push plate 17 or the push rod of the first electric push rod 31, which can detect the distance that the first electric push rod 31 pushes the push plate 17. The linear displacement sensor 32 is connected to the controller to transmit the detected data to the controller. The controller has a first formula and a second formula preset. When the medicine is placed in the placement box body 1, the controller can calculate the length occupied by each box of medicine using the first preset formula. When the controller receives the data detected by the linear displacement sensor 32, it can calculate the amount of medicine dispensed each time according to the second preset formula.

[0056] Specifically, when the first electric push rod 31 retracts to its limit position, the push plate 17 is at its limit position away from the dispensing port 13, and the linear displacement sensor 32 displays 0 data. At this time, the distance between the dispensing port 13 and the push plate 17 is a fixed length L. The number of medicines counted by the controller during dispensing is X, and the first preset formula is L / X. The controller calculates the length occupied by each box of medicine according to the first preset formula as L / X = L1. After the medicine is dispensed, the locking component 2 fixes the position of the dispensing door 14 and the placement box body 1. The first electric push rod 31 pushes the push plate 17 towards the dispensing port 13 until the medicine touches the inner wall of the placement box body 1 at the dispensing port 13. The first contact switch 171 closes and controls the first electric push rod 31 to stop. At this time, the linear displacement sensor 32 detects L2 data. The second preset formula is L2 / (L / X), that is, L2 / L1. The controller calculates the number of medicines dispensed according to the second preset formula L2 / L1. This allows for real-time updates and statistics on the current quantity of drugs in the market.

[0057] Because the pushing stroke of the first electric push rod 31 is limited, in another example of this application, the pushing device 3 includes a linear motor (not shown in the figure) fixed to the inner wall of the placement box body 1, and the push plate 17 fixed to the slider of the linear motor. The linear motor drives the push plate 17 to move. When the pushing device 3 is a linear motor, the linear displacement sensor 32 can be fixed to the main body of the linear motor, and the slider of the linear displacement sensor 32 is still fixed to the push plate 17. The linear displacement sensor 32 can detect the distance the push plate 17 moves, and thus automatically calculate the number of medicines taken out each time according to the first preset formula and the second preset formula stored in the controller.

[0058] Reference Figure 2The locking component 2 includes an electromagnet 21 fixed to the side of the placement box body 1 facing the medicine dispensing door 14. The medicine dispensing door 14 can be made of any material that can be attracted by the electromagnet 21, such as iron; or a sheet of iron can be fixed to the side of the medicine dispensing door 14 facing the medicine dispensing port 13, so that the electromagnet 21 can attract the medicine dispensing door 14 to the outer wall of the placement box body 1.

[0059] Meanwhile, in order to facilitate doctors to open the medicine dispensing door 14 and retrieve the medicine, a first gripping groove 141 is provided on the outside of the medicine dispensing door 14 to facilitate doctors to open the medicine dispensing door 14.

[0060] Reference Figure 2 To prevent the medicine dispensing door 12 from opening under external force after the medicine is placed into the placement box body 1 through the medicine dispensing port 11, a permanent magnet 122 is provided between the medicine dispensing door 14 and the placement box body 1, and a second gripping groove 121 is provided on the outside of the medicine dispensing door 12. Under normal conditions, the medicine dispensing door 12 is attracted to the inside of the placement box body 1 by the attraction of the permanent magnet 122. When medicine needs to be placed in, the medicine dispensing door 12 can be opened by applying force through the second gripping groove 121 to overcome the attraction of the permanent magnet 122.

[0061] The implementation principle of a medicine placement box according to an embodiment of this application is as follows: In use, the medicine door 12 is opened directly, and the medicine is placed inside the placement box body 1. When the medicine is placed inside the placement box body 1, the barcode scanner scans the barcode on the medicine to obtain the medicine information and transmits the scanned information to the controller. The controller counts the number of times the information transmitted by the barcode scanner is received to determine the medicine information and quantity placed inside the placement box body 1. Simultaneously, the controller also transmits the acquired and counted medicine information to the display screen. Then, the first electric push rod 31 is activated. The first electric push rod 31 pushes the medicine towards the dispensing port 13 via the push plate 17 until the medicine abuts against the inner wall of the placement box body 1 at the dispensing port 13. At this point, the first contact switch 171 closes, and the first electric push rod 31 stops operating. When medicine needs to be retrieved, the locking component 2 is released from the dispensing door 14, and the doctor can directly take the required quantity of medicine from the dispensing port 13. After retrieval, the dispensing door 14 is closed. At this time, the first electric push rod 31 once again drives the push plate 17 to move towards the medicine dispensing port 13 until the medicine is pushed to a position close to the medicine dispensing port 13. At the same time, the first linear displacement sensor 32 also detects the movement of the push plate 17 and transmits the detection data to the controller. The controller calculates the quantity of medicine taken out by a preset formula and subtracts the quantity of medicine taken out from the medicine information stored internally, thereby obtaining the real-time information of the quantity of medicine inside the placement box body 1, and transmits the medicine dispensing information and the latest information to the display screen for display.

[0062] This application also discloses an intelligent storage cabinet. (Refer to...) Figure 3and Figure 4 The intelligent storage cabinet includes a cabinet body 4 and multiple medicine storage boxes detachably connected to the cabinet body 4. One side of the cabinet body 4 has multiple slots 41 for inserting the storage box bodies 1 into. Inside the cabinet body 4, there are fixing devices 5 for securing the medicine storage boxes within the slots 41. The number of fixing devices 5 is the same as the number of slots 41, and each fixing device 5 can secure the medicine storage box.

[0063] Reference Figure 3 and Figure 4 The slots 41 are arranged in a matrix with multiple rows and columns on one side of the cabinet 4. This application uses a four-column slot arrangement as an example. Two columns of slots 41 form a group, and an installation space 42 for installing fixing devices 5 is provided between the two columns of slots 41 in the same group. The fixing devices 5 corresponding to the two columns of slots 41 in the same group are arranged in a mirror image. The installation space 42 is connected to the side of the cabinet 4 where the slots 41 are located. At the same time, an inspection door 43 is hinged to the cabinet 4 to close the installation space 42. By opening the inspection door 43, it is convenient to perform maintenance and other work on the fixing devices 5 in the installation space 42.

[0064] Reference Figure 3 and Figure 5 A lock 44 is provided between the access door 43 and the cabinet 4 to fix the position of the access door 43 on the cabinet 4. The lock 44 can be a commercially available mechanical lock. In the embodiments of this application, the lock 44 may include a lock cylinder 441 rotatably connected to the access door 43 and a lock plate 442 fixedly connected to one end of the lock cylinder 441 located in the installation space 42. The two ends of the lock cylinder 441 pass through the inner and outer sides of the access door 43, respectively. At the same time, a L-shaped locking plate 443 is fixedly connected to the cabinet 4. The locking plate 443 is located in the installation space 42, and a locking space with an upward opening is formed between the locking plate 443 and the cabinet 4 for the locking plate 442 to be inserted. The operator can directly rotate the lock cylinder 441 from the outside to rotate the lock plate 442 into the locking space, thereby fixing the position of the access door 43. When it is necessary to open the access door 43, the staff can directly insert the key into the lock cylinder 441 and operate the lock cylinder 441 to rotate in the opposite direction, so that the lock plate 442 can be rotated out from the locking space, thereby releasing the fixed relationship between the access door 43 and the cabinet 4.

[0065] To facilitate the opening of the maintenance door 43 by staff, a third grip groove 431 is provided on the outside of the maintenance door 43.

[0066] Reference Figure 4The fixing device 5 includes a fixing block 51 slidably connected within the installation space 42 and a second electric push rod 52 that drives the fixing block 51 to slide within the installation space 42 toward the slot 41. Each medicine box body 1 has a fixing groove 18 on the side facing the installation space 42 for the fixing block 51 to be inserted into. A clearance opening 411 for the fixing block 51 to slide through is also provided on the side wall of the slot 41 facing the installation space 42. When the medicine box is inserted into the slot 41, the second electric push rod 52 is directly activated, causing the fixing block 51 to slide toward the slot 41 until it is inserted into the fixing groove 18, thus fixing the medicine box in place within the slot 41.

[0067] Reference Figure 4 and Figure 6 A fourth contact switch 412 is also installed at the closed end of each slot 41. The fourth contact switch 412 is connected to the second electric push rod 52 to control the second electric push rod 52 to start. When the placement box body 1 is inserted into the slot 41, the placement box body 1 will abut against the fourth contact switch 412, the fourth contact switch 412 will close, and the second electric push rod 52 will start automatically.

[0068] Reference Figure 4 A manual unlocking device 6 is also provided between the second electric push rod 52 and the fixing block 51. When the medicine dispensing door 14 malfunctions and cannot be opened, or when it is necessary to remove the placement box body 1 from the slot 41 and the second electric push rod 52 malfunctions, the manual unlocking device 6 can be used to release the fixing block 51 from the placement box body 1. The doctor can then remove the placement box body 1 from the slot 41 and take the medicine through the medicine dispensing port 11 or place the medicine into the placement box body 1 through the medicine dispensing port 11.

[0069] The manual unlocking device 6 includes a first threaded rod 61 fixed to the push rod of the second push rod, a second threaded rod 62 fixed to the side of the fixing block 51 facing the second push rod, and a threaded cylinder 63 located between the first threaded rod 61 and the second threaded rod 62 and threadedly connected to both the first threaded rod 61 and the second threaded rod 62. The threads on the first threaded rod 61 have opposite directions to those on the second threaded rod 62. When the threaded cylinder 63 is rotated, both the body of the second electric push rod 52 and the fixing block 51 are rectangular and one side is in contact with the bottom wall of the installation space 42. Therefore, the body of the second electric push rod 52 and the fixing block 51 will not rotate with the threaded cylinder 63, and the first threaded rod 61 and the second threaded rod 62 can move closer together or further apart. When the threaded cylinder 63 is rotated, causing the first threaded rod 61 and the second threaded rod 62 to move closer together, the fixing block 51 will slide out of the fixing groove 18 and slide in the direction of the second electric push rod 52, thus unlocking the placement box body 1.

[0070] To facilitate external operation of the threaded cylinder 63 by the doctor, the manual unlocking device 6 also includes a screwing assembly 64, one end of which extends to the outside and is connected to the threaded cylinder 63. The screwing assembly 64 includes a rotating rod 641 rotatably connected to the cabinet 4. One end of the rotating rod 641 is connected to the threaded cylinder 63, and the other end extends through the inspection door 43 to the outside, with the exposed end of the rotating rod 641 flush with the outer wall of the cabinet 4. A driving bevel gear 642 is fixed to the end of the rotating rod 641 facing the threaded cylinder 63, and a driven bevel gear 643 is provided on the threaded cylinder 63. The driven bevel gear 643 rotates synchronously with the threaded cylinder 63. When it is necessary to remove the placement box body 1 from the slot 41 and the second electric push rod 52 malfunctions, the doctor can operate the rotating rod 641 from the outside. The rotating rod 641 will drive the driven bevel gear 643 to rotate via the driving bevel gear 642, thereby causing the threaded cylinder 63 to rotate.

[0071] The hole on the inspection door 43 through which the rotating rod 641 passes is slightly larger than the diameter of the rotating rod 641, so that the rotating rod 641 will not affect the opening and closing of the inspection door 43.

[0072] Meanwhile, in order to facilitate the operation of the rotating rod 641 by the doctor, a rotating groove is provided at the end of the rotating rod 641 exposed to the outside for inserting external tools or keys. By inserting external tools or keys into the rotating groove, the rotating rod 641 can be rotated by the external tools or keys.

[0073] When the driven bevel gear 643 drives the threaded cylinder 63 to rotate, the first threaded rod 61 and the second threaded rod 62 will approach each other within the threaded cylinder 63. Since the second electric actuator and the first threaded rod 61 are stationary, the threaded cylinder 63 and the second threaded rod 62 will move in the direction of the second electric actuator 52. To prevent the threaded cylinder 63 from moving in the direction of the second electric actuator 52 and causing the driven bevel gear 643 to move, thus affecting the meshing between the driving bevel gear 642 and the driven bevel gear 643, the driven bevel gear 643 is designed to slide in connection with the threaded cylinder 63.

[0074] Reference Figure 6 and Figure 7 The driven bevel gear 643 is sleeved on the threaded cylinder 63. A locking block 644 is fixedly connected to the inner wall of the driven bevel gear 643. A sliding groove 631 is provided on the outer wall of the threaded cylinder 63 along its axial direction for the locking block 644 to slide. Through the cooperation of the locking block 644 and the sliding groove 631, the driven bevel gear 643 and the threaded cylinder 63 can be slidably connected, and the two can also rotate synchronously.

[0075] If the threaded cylinder 63 is rotated by the manual unlocking device 6 to cause the fixing block 51 to slide out of the fixing groove 18, and the threaded cylinder 63 is not rotated in the opposite direction to make the first threaded rod 61 and the second threaded rod 62 move away from each other, the fixing block 51 will be directly driven into the fixing groove 18 by the second electric push rod 52. When the manual unlocking device 6 is needed to release the fixing relationship between the fixing block 51 and the box body 1, it will be impossible to remove the fixing block 51 from the fixing groove 18 by rotating the threaded cylinder 63 again.

[0076] Reference Figure 4 Therefore, the second electric push rod 52 is designed to slide unidirectionally inside the cabinet 4, so that the second electric push rod 52 can only slide in a direction away from the threaded cylinder 63.

[0077] Specifically, a limiting plate 71 is fixedly connected inside the cabinet 4. The limiting plate 71 is located on the side of the second electric push rod 52 away from the threaded cylinder 63. An abutment spring 72 is also fixedly connected between the second electric push rod 52 and the limiting plate 71. At the same time, several first teeth 73 are fixedly connected to the lower side of the second electric push rod 52. Several second teeth 74 that mesh with the first teeth 73 are installed inside the cabinet 4. The first teeth 73 and the second teeth 74 are arranged side by side along the length of the second electric push rod 52. The first teeth 73 and the second teeth 74 are used to restrict the second electric push rod 52 to move only in the direction away from the threaded cylinder 63.

[0078] Specifically, the longitudinal sections of the first tooth 73 and the second tooth 74 are both right-angled triangles. The hypotenuse of the right-angled triangle of the first tooth 73 faces the abutting spring 72, while the hypotenuse of the right-angled triangle of the second tooth 74 faces away from the limiting plate 71. This ensures that when the first tooth 73 and the second tooth 74 are engaged, their hypotenuses are in contact. Furthermore, the right-angled side of the second tooth 74 prevents the first tooth 73 from sliding towards the threaded cylinder 63.

[0079] When the first threaded rod 61 and the second threaded rod 62 are in abutting state inside the threaded cylinder 63, and manual unlocking is required, the rotating rod 641 can be operated to rotate in the opposite direction, so that the first threaded rod 61 and the second bolt rod move away from each other. Since the second threaded rod 62 abuts against the fixing groove 18 of the box body 1 through the fixing block 51, the first threaded rod 61 will drive the second push rod to slide towards the abutting spring 72 and squeeze the abutting spring 72. At this time, the first tooth 73 also slides from one second tooth 74 to another second tooth 74 close to the abutting spring 72 through the hypotenuse of its triangle. This creates a gap between the first threaded rod 61 and the second threaded rod 62. Then, the rotating rod 641 is rotated in the forward direction, causing the first threaded rod 61 and the second threaded rod 62 to move closer together. Due to the engagement of the first tooth 73 and the second tooth 74, the second electric push rod 52 will be unable to slide in the direction of the threaded cylinder 63. At this time, the second threaded rod 62 will drive the fixing block 51 to slide in the direction of the second electric push rod 52, thereby unlocking the placement box body 1.

[0080] Reference Figure 4 and Figure 6 To prevent the second electric push rod 52 from extending further after driving the fixing block 51 into the fixing groove 18, causing the second electric push plate 17 to slide away from the fixing block 51 and affecting subsequent manual unlocking, a second contact switch 511 is installed at the end of the fixing block 51 away from the second threaded rod 62. The second contact switch 511 is connected to the second electric push rod 52 to control the second electric push rod 52 to stop. When the second electric push rod 52 drives the fixing block 51 to slide into the fixing groove 18, the bottom of the fixing groove 18 will press the second contact switch 511, causing the second contact switch 511 to close, at which point the second electric push rod 52 stops.

[0081] Meanwhile, to prevent the second electric push rod 52 from being pushed close to the limit plate 71 after repeated manual unlocking and becoming unmanually unlockable again, a detection device 8 is provided between the second tooth 74 and the limit plate 71 to detect when the second electric push rod 52 slides to its extreme position close to the limit plate 71. The detection device 8 includes a detection plate 81 fixed inside the cabinet 4 and a third contact switch 82 fixed to the detection plate 81 facing the second electric push rod 52. When the second electric push rod 52 slides to its extreme position close to the limit plate 71, it will abut against the third contact switch 82. The third contact switch 82 is connected to an alarm via a wire. The alarm can be installed on the cabinet 4 or in any other suitable location. When the second electric push rod 52 abuts against the third contact switch 82, the alarm will also sound, reminding the staff to adjust the position of the second electric push rod 52 in time. The staff can simply open the access door 43 and manually move the second electric push rod 52 away from the abutment spring 72.

[0082] Reference Figure 3 and Figure 6 A control panel 45 is installed on one side of the cabinet 4. A fiber optic connector 413 connected to the control panel 45 is fixed to the closed end of each slot 41. The fiber optic connector 413 is connected to the control panel 45 via fiber optic cable.

[0083] Reference Figure 6 and Figure 8 Meanwhile, each placement box body 1 has an optical fiber interface 191 at the end opposite to the medicine dispensing port 13. The optical fiber interface 191 at the placement box body 1 is connected to the controller inside the placement box body 1. When the placement box body 1 is inserted into the slot 41, the optical fiber connector 413 is also inserted into the optical fiber interface 191. At this time, the medicine information placed in the placement box body 1 will be transmitted to the control panel 45 through optical fiber. Since the position of each optical fiber connector 413 is fixed, the placement position of each medicine is also determined. The control panel 45 can clearly display the type and quantity of medicine placed in each slot 41 in the cabinet 4.

[0084] The control panel 45 is connected to the placement box body 1 via optical fiber, allowing the locking component 2 to be opened to unlock the dispensing door 14. When a doctor needs to retrieve medication, they can directly check the quantity and location of each medication on the control panel 45 and control the dispensing door 14 to open and retrieve the medication.

[0085] Meanwhile, each placement box body 1 is equipped with a storage battery (not shown in the figure) to provide power to the electrical components inside the placement box body 1. A charging port 192 for charging the storage battery is provided at the end of each placement box body 1 opposite to the medicine dispensing port 13, and a charging head 414 for charging the placement box body 1 is fixedly connected to the closed end of each slot 41. When the placement box body 1 is installed in the slot 41, the charging head 414 is also inserted into the charging port 192 to charge the placement box body 1.

[0086] Reference Figure 3 On the same row, the fixing devices 5 corresponding to the two slots 41 in the same group are located in the same installation space 42 and are staggered in the front and back direction of height, making operation more convenient.

[0087] The implementation principle of an intelligent placement cabinet according to an embodiment of this application is as follows: During use, staff can place each type of medicine into each placement box body 1. At this time, a barcode scanner will scan the barcode on the medicine box to obtain the medicine type information. The controller will also obtain the quantity information of the medicine by counting the number of scans by the barcode scanner and transmit the medicine type and quantity information to the display screen. When the placement box body 1 is installed in the slot 41, the placement box body 1 abuts against the fourth contact switch 412 and closes. The fourth contact switch 412 controls the second electric push rod 52 to automatically start, driving the fixing block 51 into the fixing slot 18 until the second contact switch 511 closes. The second contact switch 511 controls the second electric push rod 52 to stop, thus automatically fixing the placement box body 1. In case of an emergency requiring manual contact with the fixing device 5 to fix the placement box body 1, the fixing block 51 can be released from the placement box body 1 directly through the manual unlocking device 6, and the staff can directly pull the placement box body 1 out of the slot 41.

[0088] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
