Description

Technical Field

[0001] The present invention relates to the field of medical intelligent equipment, and in particular to an intelligent medicine box and an intelligent medicine dispensing method thereof. Background Art

[0002] Medical care has always been an indispensable part of people's healthy life. An important part of medical care is taking medicine. How to follow the doctor's advice to ensure that the medicine is taken on time and in the right dosage is the key to curing the disease. Especially with the deepening of the aging of the population, there are more and more empty-nest elderly people, and the drug maintenance or rehabilitation treatment of patients with various chronic diseases has further highlighted the importance of reasonable medication. Most of the existing household medicine boxes only have storage functions, such as medical aluminum alloy medicine boxes, which have a solid shell, light aluminum material, and are waterproof and moisture-proof for storing medicines, but the internal structure is simple, the compartments are not enough, and the price is high. The timing reminder plastic butterfly medicine box has an alarm function, but its volume is small and the medicine reserve is insufficient. At present, the smart medicine box on the market has made innovations in the intelligent system, adding an APP remote care function, designing a medication reminder plan for the medicine box by binding with the mobile phone and the medicine box, recording medicines and medication information on the mobile terminal, and controlling the medicine box through a computer, but it cannot prepare different types of medicines needed for the elderly at a fixed time and quantity.

[0003] In summary, household medicine boxes have gradually evolved from storage boxes to intelligent ones, but the current smart medicine boxes on the market focus on the intelligent communication data, while ignoring the innovation of the internal mechanical structure of the medicine box, making it a storage communication tool without any innovation in the medicine box itself. Therefore, the development of smart medicine boxes still requires a more intelligent, efficient and comprehensive solution. Summary of the invention

[0004] The present invention provides an intelligent medicine box and an intelligent medicine dispensing method thereof, which solve the problems that the existing intelligent medicine box has few types of stored medicines, cannot dispense medicines on time and in quantity, and is not easy for family members to supervise patients taking medicines in time.

[0005] In order to solve the above technical problems, the present invention provides a technical solution: an intelligent medicine box includes a sealing ring, a base and a top cover, and the three cooperate to form a closed medicine box.

[0006] It also includes a main control center; a medicine outlet box is provided on the base, and a medicine outlet port is correspondingly opened on the sealing ring; the middle part of the base is fixedly connected to the first bracket, and a lower medicine outlet tray is provided on the top of the first bracket, and a first stepper motor is provided below the lower medicine outlet tray, and a servo motor is connected to the top of the optical axis of the first stepper motor; the body of the servo motor is fixedly connected to the upper medicine outlet tray, the output shaft of the servo motor passes through the upper medicine outlet tray, and a medicine storage box is installed on the top, and the medicine storage box includes a plurality of compartments with through holes at the bottom; the medicine storage box, the upper medicine outlet tray and the lower medicine outlet tray are concentrically arranged; the upper medicine outlet tray is provided with a plurality of upper medicine outlets corresponding to the through holes of the medicine storage box; the lower medicine outlet tray is provided with a lower medicine outlet, and a medicine outlet pipe which is a spiral tube is fixedly connected to the lower medicine outlet, and a first photoelectric gate is installed in the medicine outlet pipe; two conveyor belts parallel to each other are obliquely installed on the base below the medicine outlet pipe, and the outlet of the medicine outlet pipe corresponds to the inlet between the conveyor belts.

[0007] The main control center includes a single chip microcomputer, and the single chip microcomputer is connected to the first stepper motor, the steering gear, the first photoelectric gate and the conveyor belt.

[0008] Furthermore, the spacing between the two conveyor belts is 5 mm, including two driving wheels and two driven wheels, and also including two motors driving the driving wheels to rotate synchronously, and the housing of the motor is fixedly connected to the conveyor belt. The medicine dropped from the medicine outlet pipe passes through the gap between the two conveyor belts, and because the conveyor belts are elastic, the medicine can be clamped, thereby realizing the transportation of the medicine in both the upper and lower directions.

[0009] Furthermore, the medicine discharging pipe is a spiral tube, which can disperse the fallen tablets, facilitate conveyor belt transportation and allow the second photoelectric gate to more accurately detect the amount of medicine discharged.

[0010] The sealing ring is provided with a drug inlet and a recovery inlet, the inner side of the drug inlet is communicated with the drug storage box, a paddle is fixed on the outer side, a recovery box is installed at the recovery inlet, and a rocker is hinged inside the recovery box; a lifting device is provided between the drug inlet and the recovery inlet, comprising a second stepping motor connected to the main control center, a screw rod and a screw rod nut cooperating with the screw rod; the recovery box is fixedly connected to the screw rod nut; a recovery pipe is fixed on one side of the conveyor belt, and the recovery pipe is communicated with the recovery box.

[0011] Furthermore, the sides of the recovery box and the seesaw are both surrounded on three sides to facilitate the entry and exit of drugs; the enclosure behind the seesaw is provided with a counterweight to tilt the seesaw backwards, and at the same time the enclosure behind the recovery box ensures that the seesaw will not completely flip over, and will not flip over too far to cause the drugs to fall when loaded, so that the drugs can be smoothly delivered back to the medicine storage box.

[0012] Excessive drugs fall from the drug outlet pipe and enter the entrance between the two conveyor belts. The conveyor belt reverses to send the excess drugs to the pipe opening above the recovery pipe, slides through the recovery pipe and falls into the recovery box. In this way, the channel for recovering drugs is distinguished from the normal drug outlet channel, which does not affect the patient's medication on time. The first stepper motor drives the servo to rotate the medicine storage box compartment corresponding to the excess drugs to the medicine inlet; the second stepper motor drives the screw to rotate, and the screw nut drives the recovery box to make a straight line movement in the up and down direction along the screw. When the recovery box rises to the medicine inlet, the paddle acts on the seesaw, and the seesaw tilts toward the medicine inlet, causing the drugs inside the recovery box to slide into the corresponding medicine storage box compartment, and the excess drugs are automatically recovered, making it more convenient for patients to take medicine.

[0013] Furthermore, the distance between the lower drug outlet and the center of the circle is equal to the distance between the upper drug outlet and the center of the circle, and the through hole, the upper drug outlet and the lower drug outlet are of the same size. The holes with equal distances from the center of the circle and the same specifications allow the drug to fall smoothly, thereby improving the fluency and accuracy of drug dispensing.

[0014] Preferably, a second photoelectric gate is provided on the base between the medicine dispensing box and the conveyor belt, which is connected to the main control center, and can detect the amount of medicine dropped from the conveyor belt again before dispensing the medicine. When the amount of medicine passing through the second photoelectric gate has reached the set amount, the signal is fed back to the main control center, which then transmits the signal to the conveyor belt, and the motor drives the conveyor belt to rotate in the opposite direction, so that the medicine in the conveyor belt moves upward to the recovery box, thereby improving the accuracy of dispensing medicine from the medicine box.

[0015] Preferably, a third photoelectric gate is provided at the recycling entrance and is connected to the main control center for identifying the quantity of medicines to be recycled, thereby ensuring the accuracy of the medicine recycling process.

[0016] The lower medicine dispensing tray, the upper medicine dispensing tray and the medicine storage box are arranged at an angle. On the one hand, when dispensing medicine, the medicine in the compartments of the medicine storage box can reach the through hole more smoothly; on the other hand, when recovering the medicine, the medicine in the upper compartment is not easy to fall out of the medicine inlet.

[0017] Preferably, the single-chip microcomputer uses STM32F103ZET6 as the core chip, and also includes a reminder device equipped with a voice module VS1053B, a communication display device equipped with an RGB LCD screen module and a V2 capacitive screen, and an SD storage module. The STM32F103ZET6 chip is a 32-bit microcontroller based on the ARM-Cortex-M3 core, has 512K on-chip FLASH and 64K on-chip RAM, and can operate in multiple threads. The chip is connected to the mobile phone software to control the medicine box, that is, the main control center controls the steering gear and the first stepper motor to rotate according to the preset medication time, and sends a signal to the reminder device after the medicine is dispensed to remind the user to take the medicine. After the medicine is taken away, the user is reminded that the medicine is dispensed successfully and displayed on the screen of the communication display device and the mobile phone software; the user can also input and change the medication time, type and quantity through the buttons on the top cover of the medicine box, the capacitive screen or the mobile phone software, and the changed data can be synchronized to the mobile phone software; in addition, the mobile phone software can monitor the medication time and the medication dispensing work of the medicine box in real time, synchronize medication data, help users develop good medication habits, automatically generate medication health management files, and also facilitate family members to timely monitor patients at home. The user of the medicine box can connect the medicine box to the mobile phone via Bluetooth to achieve real-time correlation between the mobile phone and the medicine box.

[0018] Preferably, a handle is installed on the outside of the medicine dispensing box to facilitate the removal of the medicine dispensing box filled with medicines from the inside.

[0019] Preferably, the top cover can be opened and closed, so as to be convenient for replenishing the medicine in the medicine storage box from above. In addition, a medicine adding port is also provided on the top cover, and medicine can be added into the compartment corresponding to the medicine adding port by rotating the medicine storage box.

[0020] Preferably, the compartments inside the medicine storage box are in a diamond shape, so that the medicine to be outputted can more easily reach the through hole at the bottom vertex, making the medicine output smoother; at the same time, after such a setting, it is convenient for the through hole and the upper medicine outlet to be staggered, so as to better seal the medicine storage box during the non-drug output period. That is, in the initial position, the upper medicine outlet of the upper medicine outlet plate is located in the middle of the two through holes of the medicine storage box, so as to seal the bottom of the medicine storage box and prevent the medicine from falling during the non-drug administration period.

[0021] The present invention also provides an intelligent medicine dispensing method of the intelligent medicine box, which is specifically:

[0022] 1. For tablets to be discharged from the warehouse, the medicine storage box, the upper medicine tray and the lower medicine tray are sequentially arranged concentrically, and the through hole of the medicine storage box, the upper medicine outlet of the upper medicine tray and the lower medicine outlet of the lower medicine tray are positioned in correspondence, and then the first stepper motor is used to drive the servo housing to drive the upper medicine tray and the medicine storage box to rotate, and the servo output shaft is used to control the rotation of the medicine storage box to adjust the connectivity of the through hole, the upper medicine outlet and the lower medicine outlet, so that the tablets in the selected compartment of the medicine storage box can be discharged;

[0023] 2. Precise drug supply. Two parallel conveyor belts are placed on the lower side of the drug outlet pipe connected to the lower drug outlet. The outlet of the drug outlet pipe corresponds to the inlet between the two conveyor belts. The first photoelectric gate is used on the drug outlet pipe to control the drug output quantity. The two conveyor belts make the tablets flat to eliminate the adhesion of the tablets. The second photoelectric gate is used at the conveyor belt outlet to detect the drug output quantity. If there are excess tablets, the conveyor belt is reversed and the excess tablets are sent to the recovery pipe on the lower side of the conveyor belt.

[0024] 3. Recycling of excess tablets: The recycling pipe sends the excess tablets into the recycling box, and the screw nut device and the recycling box are used to lift the excess tablets to the medicine inlet on the upper part of the medicine box. At the same time, the servo controls the medicine storage box step 1 to rotate the medicine discharging compartment to the position corresponding to the medicine inlet, so as to recycle the excess tablets sent from the medicine inlet.

[0025] Compared with the prior art, the essential features of the present invention are: the arrangement of multiple compartments and through holes in the medicine storage box strengthens the storage function and medicine dispensing function of the medicine box; the cooperation of the servo and the stepper motor and the application of the photoelectric gate improves the mechanization degree and accuracy of the medicine dispensing of the medicine box; in addition, when the photoelectric gate detects that the medicine needs to be recycled, the conveyor belt reverses and sends the medicine into the recycling pipe, and the excess medicine enters the recycling box equipped with a seesaw from the recycling pipe, and the excess medicine in the seesaw is sent back to the corresponding compartment of the medicine storage box through the lead screw and the lead screw nut, thereby realizing accurate medicine dispensing and intelligent recycling; the STM32F103ZET6 single-chip microcomputer is used to control the medicine box, and the mobile phone software is used to control the operation of the medicine box, so that the medicine box is responsive and the intelligence is significantly improved, which makes the patient's operation simpler, ensures correct and timely medication, and helps to improve the treatment effect.

[0036] Example 1

[0037] A smart medicine box includes a sealing ring 26, a base 1 and an openable top cover 2, which cooperate to form a closed medicine box; a button 3, a reminder device 4, a communication display device 5 and a medicine adding port 32 are arranged on the top cover 2. When initially adding medicine, medicine can be added to the inside of the medicine box by opening the medicine adding port 32.

[0038] The base 1 is provided with a medicine outlet box 21, and a medicine outlet opening is provided at the corresponding position below the front of the sealing ring 26. The middle of the base 1 is fixedly connected to the first bracket 16, and the lower medicine tray 11 is obliquely installed at the top of the first bracket 16. The first stepper motor 14 is installed below the lower medicine tray 11, and the top of the optical axis 15 of the first stepper motor 14 is connected to the steering gear 13; the body of the steering gear 13 is fixedly connected to the upper medicine tray 10. The output shaft of the steering gear 13 passes through the upper medicine tray 10, and a medicine storage box 6 is installed at the top. The medicine storage box 6 includes 8 diamond-shaped compartments with through holes 7 at the bottom; the medicine storage box 6, the upper medicine tray 10, and the lower medicine tray 11 are concentric and all are inclined. The upper medicine dispensing tray 10 is provided with 8 upper medicine dispensing ports 8 of the same size and position as the through hole 7; the lower medicine dispensing tray 11 is provided with a lower medicine dispensing port 9 at the same distance from the center of the circle, and a medicine dispensing pipe 17 of a spiral tube is fixedly connected to the lower medicine dispensing port 9, and a first photoelectric gate 12 is installed in the medicine dispensing pipe 17. Two conveyor belts 19 parallel to each other and with a spacing of 5 mm are obliquely installed on the base 1 below the medicine dispensing pipe 17, and two motors 18 drive the driving wheels of the two conveyor belts 19 respectively to realize synchronous operation; the outlet of the medicine dispensing pipe 17 corresponds to the inlet between the two conveyor belts 19. A second photoelectric gate 20 is provided on the base 1 between the medicine dispensing box 21 and the conveyor belt 19.

[0039] In addition, the medicine box is provided with a main control center, including a single chip microcomputer, which is connected with a button 3, a reminder device 4, a communication display device 5, a first photoelectric gate 12, a steering gear 13, a first stepper motor 14, a conveyor belt 19, and a second photoelectric gate 20. Specifically, the main control center uses STM32F103ZET6 as a core chip, and also includes a reminder device 4 equipped with a voice module VS1053B, a communication display device 5 with an RGB LCD screen module and a V2 capacitive screen, and an SD storage module.

[0040] The STM32F103ZET6 single chip microcomputer is connected to the mobile phone software, and the medicine dispensing time, medicine dispensing type and medicine dispensing quantity can be set through the button 3 on the top cover 2, the capacitive screen or the mobile phone software.

[0041] When the quantity of medicines discharged is the set quantity, the type of medicines discharged is one, and the set medication time is reached, the first stepper motor 14 is started, so that the upper medicine plate 10 rotates to the upper medicine outlet 8 and the lower medicine outlet 9. The signal pin corresponding to the servo 13 on the single-chip microcomputer sends a square wave pulse signal with a period of 20ms and a width of 1ms, so that the medicine storage box 6 corresponding to the medicine where the grid is located rotates to the corresponding position of the upper medicine outlet 8 and the lower medicine outlet 9. At this time, the through hole 7, the upper medicine outlet 8, and the lower medicine outlet 9 are connected, and the medicine falls. The first photoelectric gate 12 detects that the medicine has fallen, and the motor 18 starts to work. After passing through the medicine outlet pipe 17, the medicine falls into two sets of synchronously running conveyor belts 19 with a model of 2GT-10mm, and then falls into the medicine box 21 after being transported by the conveyor belt 19 through the second photoelectric gate 20, and the medicine is discharged.

[0042] The motor 18 stops working after the medicine passes through the second photoelectric gate 20, and then the first stepper motor 14 drives the servo 13 to rotate, so that the through hole 7, the upper medicine outlet 8 and the lower medicine outlet 9 are misaligned, and the medicine outlet channel is closed. The communication display device 5 and the mobile phone software will both show that the medicine is successfully dispensed, and then the system enters a dormant state, waiting for the next medicine dispensing time to arrive.

[0043] Example 2

[0044] When putting medicine, set what kind of medicine is placed in each compartment of the medicine storage box 6 through the mobile phone software, and set the time and dosage of each medicine. When the number of medicines discharged is equal to the set number, there are two types of medicines discharged, and the discharge time of the required medicine is reached, the first stepper motor 14 and the steering gear 13 are started in sequence, and the upper medicine discharging plate 10 and the medicine storage box 6 rotate until the compartment where the medicine is located is at the lowest position on the inclined medicine storage box 6, and the through hole 7 is connected with the upper medicine outlet 8, the lower medicine outlet 9 and the medicine outlet pipe 17. After the first medicine is discharged according to Example 1, the signal pin corresponding to the steering gear 13 on the single-chip microcomputer outputs a square wave pulse signal, which again rotates the compartment where the second medicine is located to the upper tube mouth corresponding to the medicine outlet pipe 17, and repeats the medicine discharging method of Example 1 so that the medicine finally falls into the medicine discharging box 21, and the medicine discharging is completed. The system enters a dormant state and waits for the next medicine discharging time to arrive.

[0045] When taking more than two drugs, the drug dispensing steps are the same. After one drug is fully dispensed, the next drug is delivered.

[0046] Example 3

[0047] The sealing ring 26 of the intelligent medicine box is also provided with a medicine inlet 30 and a recycling inlet. The inner side of the medicine inlet 30 is connected to the medicine storage box 6, and a paddle is fixed on the outer side. A recycling box 24 is installed at the recycling inlet. A seesaw 25 is hinged inside the recycling box 24. Both the recycling box 24 and the seesaw 25 are semi-enclosed structures with enclosures on three sides, which are convenient for the entry and exit of medicines. A counterweight is arranged inside the enclosure on the rear side of the seesaw 25 to keep it in a backward tilted state, and the enclosure on the rear side of the recycling box 24 ensures that the seesaw 25 does not overturn backward and spill medicines. A lifting device is arranged between the medicine inlet 30 and the recycling inlet, including a second stepping motor 27 connected to the main control center, a screw rod 23, a coupling 28, and a screw rod nut 29 matched with the screw rod 23; the recycling box 24 is fixedly connected to the screw rod nut 29; a recycling pipe 22 arranged obliquely is fixed below one side of the conveyor belt 19, and the end of the recycling pipe 22 is connected to the recycling box 24.

[0048] The coupling 28 is installed below the second stepping motor 27 to drive the screw 23 to rotate, so that the screw nut 29 drives the recovery box 24 to perform linear motion in the up and down directions.

[0049] When the recovery box 24 rises to this position, the paddle fixed on the outside of the medicine inlet 30 acts on the seesaw 25, and the seesaw 25 tilts forward to allow the medicine inside the recovery box 24 to slide into the medicine storage box 6 through the seesaw 25 and the medicine inlet 30, indirectly improving the accuracy of medicine dispensing, realizing intelligent medicine recovery, and making it more convenient for patients to take medicine.

[0050] Specifically, when the drugs are adhered and the drug quantity is greater than the set quantity, and the drug type is one, after the set medication time is reached, the first stepper motor 14 and the steering gear 13 are started. The first stepper motor 14 drives the upper drug dispensing plate 10 to rotate, and the single-chip microcomputer corresponding to the signal pin of the steering gear 13 sends a square wave pulse signal with a period of 20ms and a width of 2ms to rotate the drug storage box 6 corresponding to the drug grid to the position where the through hole 7, the upper drug outlet 8, and the lower drug outlet 9 are connected, and the drug falls.

[0051] The first photoelectric gate 12 feeds back the number of shading times to the single-chip microcomputer. After passing through the medicine discharging pipe 17 and the conveyor belt 19, the second photoelectric gate 20 starts to check and record the amount of medicine discharged. When the set amount of medicine is reached, the feedback light signal causes the single-chip microcomputer in the main control center to control the motor 18 to reverse, so that the excess medicine in the conveyor belt 19 moves upward and falls into the recovery box 24 through the recovery pipe 22. The third photoelectric gate 31 detects that the medicine has fallen into the recovery box 24, and the second stepper motor 27 starts to rotate, and the screw 23, the coupling 28 and the screw nut 29 work together to lift the medicine. While the medicine is being lifted in the recovery box 24, the signal is transmitted to the first stepper motor 14 and the steering gear 13 part, and the upper medicine discharging tray 10 and the medicine storage box 6 are rotated to rotate the compartment where the medicine has just been discharged to below the medicine inlet 30 without falling.

[0052] When the recovery box 24 is raised to the medicine inlet 30, the seesaw 25 of the recovery box 24 is tilted by the paddle, and the medicine slides from the seesaw 25 to the original compartment of the medicine storage box 6. When the medicine falls back to the original compartment of the medicine storage box 6, the medicine dispensing is completed, and the system enters a dormant state, waiting for the next medicine dispensing time to arrive.

[0053] If there are multiple types of drugs to be output and they are greater than the set quantity, the above steps will be repeated for each type of drug in turn, that is, after the excess drugs are recovered, the next drug will be output.

[0054] The use of this intelligent medicine box, on the one hand, improves the storage function inside the medicine box, and multiple compartments allow patients to store a variety of medicines, which is applicable to a wider range of people; on the other hand, through the design of the photoelectric detection device, the conveyor belt 19 and the lifting device, the intelligence and mechanization level of the medicine box are improved, ensuring that the medicine box automatically and accurately dispenses medicines, which is convenient for assisting patients to take medicines better according to the doctor's instructions and develop a habit of taking medicines.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
