Technical Field

[0001] The present invention relates to the technical field of intelligent medicine boxes, and particularly to an intelligent medicine box for the elderly and its medication reminder system. Background Art

[0002] The elderly's non-compliance with taking prescription drugs as prescribed easily leads to poor treatment effects, disease deterioration, and even new health risks. Therefore, an intelligent medicine box designed specifically for the elderly helps the elderly take medicine on time and in the right amount through a timing reminder function, avoiding health risks caused by forgetting or taking the wrong medicine.

[0003] Currently, intelligent medicine boxes usually integrate voice prompts, display screens, and wireless transmission modules, which can record and upload medication information to family members or medical staff for remote monitoring.

Detailed implementation mode

[0036] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention will be further described in conjunction with the accompanying drawings.

[0037] See Figures 1 to 5 , on the one hand, the present invention provides an intelligent medicine box for the elderly, including: a box body 1, a plurality of medicine storage cavities 2 are arranged in the box body 1, a transmission roller 3 is arranged in the medicine storage cavity 2, one end of the transmission roller 3 is communicated with the side surface of the box body 1, a medicine outlet cover cylinder 4 is arranged on the side surface of the box body 1, the medicine outlet cover cylinder 4 covers the end of the transmission roller 3, the other end of the transmission roller 3 is connected with a guide roller 5, the other end of the guide roller 5 passes through the first partition 6 arranged in the box body 1 and the other side surface of the box body 1, and is connected with a braking component arranged on the other side surface of the box body 1, a second partition 7 is arranged in the box body 1, a control cavity 8 is arranged on the side of the second partition 7, a controller 9 and a driving motor 10 are arranged in the control cavity 8, the output shaft of the driving motor 10 is connected with a plurality of guide rollers 5 through a linkage component, and the braking component and the driving motor 10 are both connected with the controller 9.

[0038] It should be noted that the controller 9 adopts an STM32 single-chip microcomputer or a SMART200 PLC controller 9, and this controller 9 drives the motor 10 and the braking component to improve the intelligence of the medicine box. The first partition 6 is a horizontal partition, which forms a plurality of medicine storage cavities 2 in the box body 1 by blocking and separates the linkage component for driving the guide roller 5, and the second partition 7 is used to separate the medicine storage cavity 2 and the control cavity 8 to prevent the transmission roller 3 in the medicine storage cavity 2 from interfering with the normal operation of the driving motor 10 in the control cavity 8. The transmission roller 3 is a multi-page spiral roller, and the medicine can be placed between the pages. Through the continuous rotation of the transmission roller 3, the medicine can be continuously transmitted and finally output.

[0039] Specifically, by triggering the controller 9 to send a medication reminder signal, the braking component is activated. The braking component repels one of the wire rollers, causing the guide roller 5 to advance towards the linkage component and engage. Then, the drive motor 10 is started. The drive motor 10 drives the linkage component to rotate. The corresponding rotating guide roller 5 drives the transfer roller 3 to rotate, causing the medication placed on the transfer roller 3 to advance towards the medicine outlet cover cylinder 4 as the transfer roller 3 rotates. After multiple rotations, the medication at the very end of the transfer roller 3 is finally output at the outlet of the medicine outlet cover cylinder 4, thus facilitating the elderly to take the medicine according to the output medication without having to identify the medicine, improving the home treatment effect.

[0040] In this embodiment, the linkage component includes a plurality of first gears 11. The first gears 11 are rotatably connected to the first partition 6 and slidably connected to the guide roller 5 on the other side. The guide roller 5 is provided with a first latch that slidably engages with the transfer roller 3. The plurality of first gears 11 are connected to the output shaft of the drive motor 10 through a first transmission belt 12. The guide roller 5 is provided with a second latch 13, and the first gear 11 is correspondingly provided with a latch hole. When the guide roller 5 moves towards the first gear 11, the second latch 13 engages with the latch hole. Among them, the output shaft of the drive motor 10 drives the guide roller 5 and the first gear 11 with stable engagement to rotate. The transfer roller 3 outputs the medication through the outlet of the medicine outlet cover cylinder 4. Among them, an induction element 14 is provided at the bottom of the outlet of the medicine outlet cover cylinder 4.

[0041] It should be noted that at least 6 first gears 11 are provided. Correspondingly, at least 6 guide rollers 5 are provided. The first latch and the second latch 13 have the same size.

[0042] Exemplarily, the controller 9 drives the braking component to repel one of the 6 guide rollers 5. The guide roller 5 advances towards the first gear 11 and the transfer roller 3, causing the first latch to engage with the transfer roller 3 and simultaneously causing the second latch 13 to engage with the latch hole. Then, the controller 9 starts the drive motor 10. The output shaft of the drive motor 10 rotates, and the guide roller 5 and the first gear 11 with stable engagement are rotated through the first transmission belt 12, thereby driving the transfer roller 3 to rotate. The medication is continuously rotated and output through the transfer roller 3, and finally output through the outlet of the medicine outlet cover cylinder 4 and falls into the induction element 14. When the patient takes the medicine, the induction element 14 senses whether the patient's finger has taken the medicine. If the medicine is not taken for a long time, a signal is sent by the controller 9 to the remote terminal for monitoring, such as the mobile phone terminal used by the patient's family member.

[0043] In this embodiment, the output shaft of the drive motor 10 is further connected to a second transmission belt 15. The second transmission belt 15 is connected to a plurality of absorption components. The bottom ends of the absorption components communicate with the medicine storage cavity 2. The output ends of the plurality of absorption components are communicated through a long pipe 16. The end of the long pipe 16 is communicated with a short pipe 17. The other end of the short pipe 17 passes through the second partition 7 and communicates with a conversion part provided at the top of the control cavity 8.

[0044] While the driving motor 10 drives the first conveyor belt 12 to rotate, by using the kinetic energy of its rotation, a second conveyor belt 15 is provided to drive an absorption assembly, which is used to absorb the moisture and drug powder in the medicine storage cavity 2. After the absorption assembly is started, it absorbs the moisture and drug powder in the medicine storage cavity 2 and concentrates them in the long tube 16 connected to the output nozzle, and then inputs them into the conversion part through the short tube 17 for dehumidification and filtration.

[0045] Furthermore, the absorption assembly includes an absorption cylinder 18. The bottom end of the absorption cylinder 18 is communicated with the storage cavity. A rotating fan 19 is provided at the top end of the absorption cylinder 18. An air delivery head 20 is provided at the top of the rotating fan 19. A plurality of air delivery heads 20 are communicated through the long tube 16. The long tube 16 is communicated with the conversion part through the short tube 17. The starting end of the conversion part is connected to the output shaft of the driving motor 10 through a third conveyor belt 21.

[0046] It should be noted that at least 6 groups of absorption assemblies are provided.

[0047] Exemplarily, the second conveyor belt 15 drives the rotating fan 19 to rotate. The rotating fan 19 forms a negative pressure state. The moisture and powder are output to the air delivery head 20 through the absorption cylinder 18 and the rotating fan 19, enter the long tube 16 at the air delivery head 20, and are input into the conversion part through the short tube 17.

[0048] Furthermore, the conversion part is a conversion box 22. A third partition 23 is provided in the conversion box 22. A first air storage grid 24 and a second air storage grid 25 are provided on the left and right sides of the third partition 23. A second gear 26 is provided in the second air storage grid 25. Rotating rollers 27 are respectively provided at the top and bottom ends of the second gear 26. The rotating rollers 27 are respectively rotatably connected to the inner top surface and the bottom surface of the second air storage grid 25. Heat generating stickers 28 are provided on both the inner top surface and the bottom surface of the second air storage grid 25. The first air storage grid 24 is used to receive the air filtered by the third partition 23 in the second air storage grid 25 and is communicated with the long tube 16. A one-way solenoid valve is provided at the bottom of the second air storage grid 25. The one-way solenoid valve is communicated with the long tube 16 through a zigzag tube 29.

[0049] When moisture and powder enter the second air storage compartment 25, using the kinetic energy of the drive motor 10, through the third transmission belt 21, the third gear is driven to rotate. The heat energy generated by the rotation of the rotating roller 27 connected by the third gear is transmitted to the heat generating patch 28 and contacts the air, which can generate sufficient heat to dehumidify the moisture, convert the moisture into dry air. At the same time, when the dehumidified air flows into the first air storage compartment 24, the drug powder is filtered out through the third partition 23, and the moisture is converted into clean air. After the rotating fan 19 stops rotating, the controller 9 opens the one-way solenoid valve to let the clean gas. The air in the first air storage compartment 24 is input into the zigzag pipe 29 through the one-way solenoid valve, input into the long pipe 16 through the zigzag pipe 29, input into the air delivery head 20 and the absorption cylinder 18 through the long pipe 16, and finally input into the medicine storage cavity 2 for drying, thereby improving the dryness of the medicine in the medicine storage cavity 2 and preventing the medicine from getting damp and deteriorating.

[0050] In this embodiment, an opening and closing plate 30 is provided on the top surface of the medicine storage cavity 2. Photoelectric sensors are arranged in an array on the bottom surface, side surface and the inner top surface of the opening and closing plate 30 of the medicine storage cavity 2. The photoelectric sensors are connected to the controller 9.

[0051] The opening and closing plate 30 is provided with a silica gel sealing strip, and its periphery is tightly connected to the top surface of the medicine storage cavity 2. A grasping knob is arranged on the top surface of the opening and closing plate 30 to facilitate grasping the grasping knob to open and close the opening and closing plate 30. And photoelectric sensors are arranged in an array on its inner top surface, and at the same time, the photoelectric sensors are arranged on the bottom surface and side surface of the medicine storage cavity 2, which is convenient for the controller 9 to analyze the quantity of the medicine stored in the medicine storage cavity 2 and prompt whether to store the medicine according to the quantity of the medicine.

[0052] In this embodiment, the braking assembly includes a braking cover 31. An inductance coil 32 is provided on the inner top surface of the braking cover 31, and a prompting element is provided on the outer top surface. The inductance coil 32 is connected to the prompting element controller 9. A limiting sliding part is arranged below the inductance coil 32, and a guide roller 5 is slidably connected to the inner side of the limiting sliding part. The end of the guide roller 5 is magnetically connected to the inductance coil 32.

[0053] The controller 9 controls the on-off power supply of the inductance coil 32 to activate the magnetism of the inductance coil 32. When the controller 9 is powered on, the inductance coil 32 generates magnetism, and at the same time, a repulsive force is generated on the guide roller 5, causing the guide roller 5 to move towards the first gear 11, so that the first clamping block and the second clamping block 13 of the guide roller 5 are respectively clamped with the transmission roller 3 and the first gear 11. Then the controller 9 starts the drive motor 10, drives the first gear 11 to rotate through the first transmission belt 12, and drives the transmission roller 3 to rotate, continuously outputting the medicine from the medicine storage cavity 2. When the inductance coil 32 is powered off, the magnetism is reversely magnetically connected, causing the guide roller 5 to move upward. The first clamping block and the second clamping block 13 of the guide roller 5 are separated from the transmission roller 3 and the first gear 11, and the transmission roller 3 cannot rotate, that is, the medicine cannot be transmitted. The pages provided at the end of the transmission roller 3 limit the output of the medicine to prevent the medicine from falling.

[0054] Preferably, the limiting sliding part includes a limiting cylinder 33. A vibrating piece 34 is arranged inside the limiting cylinder 33. A striking rod 35 is arranged on the circumferential side of the guiding roller 5. The striking rod 35 is in contact with the vibrating piece 34.

[0055] When the guiding roller 5 slides up and down, that is, it slides up and down inside the limiting cylinder 33. When the guiding roller 5 moves downward, the striking rod 35 at its top slides downward. And when the first clamping block is clamped with the transmission roller 3, the striking rod 35 is correspondingly in contact with the vibrating piece 34. Then, after the guiding roller 5 rotates, the striking rod 35 knocks on the vibrating piece 34, causing the vibrating piece 34 to generate a vibrating effect to prompt the patient that they can take the medicine.

[0056] In addition, while the controller 9 powers on the inductance coil 32, it activates the flashing light at the top of the braking cover 31. Among them, one flashing light corresponds to the rotating guiding roller 5, which is convenient for the patient to identify the medicine that can be taken from the corresponding medicine storage cavity 2.

[0057] See Figures 6 to 7 , on the other hand, the present invention provides an intelligent medicine box taking medicine reminder system for the elderly, including: an information receiving module for receiving the patient's identity data, medication data, medication cycle data, and medication time period data; a medication reminder module for receiving the data output by the information receiving module and sending out a reminder signal, the reminder signal including sound, light, and vibration; a medicine dispensing module for receiving the reminder of the medication reminder module and driving the guiding roller 5 through the driving motor 10, and the guiding roller 5 drives the transmission roller 3 to output the medicine in the medicine storage cavity 2 through the medicine dispensing cover cylinder 4; a cyclic reminder module for making a corresponding judgment signal according to whether the medicine output by the medicine dispensing module is received, and sending the judgment signal to the remote monitoring terminal.

[0058] The information receiving module receives the user's identity data, which includes the patient's name, gender, age, medical records, ID number, and family member data. The medication data includes the drug category the patient takes and the number of medications taken. The medication cycle data includes how long the current medication is taken, such as one course of treatment (one month) or two courses of treatment. The medication time period data includes morning, noon, afternoon, or morning and afternoon, or noon and evening. The information receiving module enters the information using a mobile terminal remotely connected to the controller 9 for reading and writing. At the same time, a fingerprint verification port is provided on the box body 1 for the patient to actively start the drive motor 10 through the controller 9 in case of an emergency, so that the drive motor 10 performs subsequent actions. When it is time to take medicine, such as at 9 am, the medicine-taking reminder module receives the signal sent by the information receiving module, and the medicine-taking reminder module starts to emit audible, visual, and vibration reminder signals to facilitate the patient to receive the reminder information. The medicine dispensing module is used to receive the electrical signal of the medicine-taking reminder module. After receiving it, it drives the guide roller 5 to rotate by starting the drive motor 10, and then drives the transmission roller 3 to rotate to output the medicine in the medicine storage cavity 2 through the medicine dispensing cover cylinder 4 for the patient to take the medicine. At the same time, the circulation reminder module detects whether the medicine has been grabbed by the patient. If not, it sends a judgment signal to the remote monitoring terminal (mobile terminal), and the patient's family member learns through the remote monitoring terminal that the patient has not grabbed the medicine and reminds the patient not to forget to take the medicine through a phone call.

[0059] Furthermore, the medicine dispensing module is provided with an algorithm unit, and the algorithm unit is connected to the photoelectric sensor through the controller 9; the photoelectric sensor is used to receive the drug particle data in the medicine storage cavity 2 and send it to the algorithm unit through the controller 9, and the algorithm unit uses a statistical algorithm to determine the drug particle data;

[0060] Among them, the steps for the statistical algorithm to determine the particle data include the following:

[0061] Step S1: Arrange a photoelectric sensor array on the inner wall and / or bottom of the medicine storage cavity 2 to form a regularly distributed detection grid;

[0062] Step S2: Collect the occlusion state signals of each photoelectric sensor to generate a drug image matrix, where the occlusion state is marked as 1 and the unoccluded state is marked as 0;

[0063] Step S3: Perform a connected component analysis on the drug image matrix to identify adjacent occluded regions of the drug image matrix and count the number of connected components;

[0064] Step S4: According to the preset drug morphology parameters, correct the error of the number of connected components through a probability statistical model and output the final drug quantity.

[0065] It should be noted that the connected component analysis includes traversing the binary matrix (drug image matrix) using the 8-neighborhood labeling method, calculating the area of the bounding rectangle for each connected component. If the area exceeds a preset threshold, it is determined as multiple overlapping tablets. Finally, the number of tablets in the overlapping area is estimated based on the average projected area of the tablets, thereby preventing the overlapping drugs from affecting the accurate judgment of the quantity.

[0066] In one example, a grid detection state is formed by the photoelectric sensors provided on the inner wall and / or bottom of the medicine storage cavity 2 and the inner top surface of the opening and closing plate 30 to obtain a drug distribution state diagram. If there is an overlapping image, it is marked as 1, and if there is no overlap, it is marked as 0. Combining the connected component analysis and the probability correction model effectively solves the error problems caused by tablet overlap and environmental interference in the traditional photoelectric counting method. Finally, after the connected component analysis and the probability correction model calculate the number of drugs in the medicine storage cavity 2, a signal is sent to the remote monitoring terminal through the controller 9, which is convenient for recording the remaining drugs in the medicine storage cavity 2, and determining whether to store more drugs according to the remaining drugs.

[0067] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
