Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically relating to an intelligent medicine box with drug verification and self-service dispensing functions. Background Technology

[0002] In the prior art, refer to Chinese invention patents with publication numbers CN112489754A, CN110974692A, and CN108969354A, all entitled "A Smart Pillbox and its Control Method". The aforementioned prior art discloses a typical smart pillbox solution, which generally includes: (1) One or more drug storage compartments: used for storing drugs (2) An automatic dispensing mechanism: usually a rotating disk or paddle structure driven by a motor, which dispenses a single dose of medicine to the dispensing port at a set time.

[0003] (3) A control unit: used to receive the medication plan set by the user and control the dispensing mechanism to perform actions.

[0004] (4) A communication module: used to connect with mobile terminals (such as mobile APP) to realize the setting of medication plans and the synchronization of medication records.

[0005] (5) A reminder device, such as a display screen, buzzer or indicator light, for reminding you when to take the medication.

[0006] While existing technologies have addressed the issue of "forgetting to take medication" to some extent, they suffer from the following inherent and unresolved flaws, particularly in addressing the core issue of medication safety: (1) The drug access process is completely lacking, making it impossible to eliminate the risks of "blindly trusting medicine" and misuse of counterfeit and substandard drugs. Existing smart pillboxes are merely passive "dispensing containers," failing to identify or verify the type, source, and safety of the drugs they contain. Users (especially elderly people with declining cognitive abilities) can pre-fill the pillbox with any unprescribed "folk remedies," health products with exaggerated efficacy claims, or even counterfeit and substandard drugs. The device cannot identify, warn against, or intercept such high-risk drugs, and will still distribute them on time, effectively becoming an accomplice to "blindly trusting medicine" and posing a huge risk to medication safety. Some smart pillboxes are linked to the prescription system, but rural or community clinics may not be connected to the prescription system, resulting in medications prescribed by rural or community clinics frequently visited by the elderly not being applicable to the smart pillbox, thus limiting the applicability of the smart pillbox.

[0007] (2) The medication behavior verification mechanism is rudimentary and cannot effectively prevent "missed doses, incorrect doses, and overdose". Most existing technologies only use "medicine box lid opening and closing sensors" or "timers" to determine whether a patient has taken medication, and the verification logic is extremely fragile. For example, an elderly person may open the medicine box but not take out the medicine (missed dose); an elderly person may open the medicine box multiple times due to forgetfulness and take out more medicine than the prescribed dose (overdose); the system cannot determine whether the medicine taken out has been taken correctly or put back. This simple detection method cannot effectively verify the core behavior of "whether the correct dose of medicine has actually been taken", and the accuracy of medication cannot be guaranteed.

[0008] (3) The dispensing mechanism has poor compatibility and insufficient reliability, which can easily lead to secondary risks. Its mechanical dispensing structure (such as paddles and gears) is very prone to problems such as drug jamming, leakage, or drug breakage for irregularly shaped tablets, capsules, and especially traditional Chinese medicine pills that are easy to stick together or made of soft materials. After long-term use, wear and tear of mechanical parts will lead to a decrease in dispensing accuracy, resulting in a hidden fault of "occasionally dispensing one less tablet", which is difficult for users to detect and has a serious impact on the treatment effect.

[0009] (4) The operation is complicated and highly dependent on the network. The medication plan setting is highly dependent on the mobile APP, which is extremely unfriendly to the elderly who are not familiar with smart devices. At the same time, the device has a short battery life (usually 7-10 days) and cannot synchronize data with family members in the absence of network, which limits its application scenarios.

[0010] In summary, existing smart pillbox technology essentially only addresses the issues of "reminders" and "dispensing," leaving a significant gap in addressing the core medical need of "medication safety." Therefore, there is an urgent need for a smart pillbox solution capable of monitoring and managing the entire process from "drug source" to "dose endpoint." Utility Model Content

[0011] To solve the above-mentioned technical problems, this utility model provides an intelligent medicine box with drug verification and self-service dispensing functions.

[0012] The purpose of this utility model is achieved by the following technical solution. According to this utility model, a smart medicine box with drug verification and self-service dispensing functions includes a medicine box body, a central intelligent control area, several medicine compartments, and indicator lights corresponding to the medicine compartments. The bottom of each medicine compartment has a medicine compartment placement platform with an integrated medicine compartment pressure sensor. A medicine compartment is placed on the platform, and an infrared sensor and an ambient light controlled by the infrared sensor are installed inside each compartment. A flip-top for closing the medicine compartment is provided at the opening of each compartment. The top of the central intelligent control area has a central verification platform with an integrated platform pressure sensor and a display screen. The front of the central intelligent control area has a voice announcer, a QR code scanning camera, and an infrared proximity sensor or accelerometer. The bottom of the central intelligent control area has a power module, and the rear has a charging interface electrically connected to the power module. The indicator lights, medicine compartment pressure sensor, infrared sensor, platform pressure sensor, display screen, voice announcer, QR code scanning camera, infrared proximity sensor or accelerometer, and power module are electrically connected to the control module. The control module communicates with a cloud platform via a communication module, and the cloud platform communicates with a family management terminal.

[0013] Furthermore, an NFC reading chip electrically connected to the control module is installed on the front side of the central intelligent control area.

[0014] Furthermore, an auxiliary camera electrically connected to the control module and used for OCR text recognition is installed on the front side of the central intelligent control area.

[0015] Furthermore, the central intelligent control area is equipped with an auxiliary camera located above the central verification platform and electrically connected to the control module.

[0016] Furthermore, the communication module is a WiFi module and / or a 4G module.

[0017] Furthermore, the control module includes an MCU, an edge AI computing chip, a clock circuit, a memory, and a power management chip.

[0018] Furthermore, a physical confirmation button is installed at the top of the central intelligent control area for pressing after taking the medication.

[0019] Compared with the prior art, the advantages of this utility model are: Through a three-tiered drug identification system consisting of an NFC reader chip (9+), a QR code scanning camera (10+), and an auxiliary camera (11), and by connecting with a national database, various drugs can be fully identified. This achieves a fundamental shift from "passive drug distribution" to "active interception," cutting off the circulation path of superstitious drug use and counterfeit drugs at the source.

[0020] By using infrared sensor 21, pressure sensor and edge AI computing chip, the verification of medication behavior is upgraded from simple "opening the lid" to closed-loop verification of "action + vision", which greatly reduces the error rate of missed doses and multiple doses, and the verification accuracy is significantly higher than that of a single sensor.

[0021] It greatly reduces the learning cost for the elderly, the automatic drug identification simplifies the medication dispensing process, and the voice broadcaster 19 and indicator light 20 are user-friendly, making it easier for the elderly to operate independently.

[0022] It significantly reduces the monitoring burden on family members. Reliable real-time alerts and medication reports allow family members to accurately grasp the elderly person's medication situation, eliminating the anxiety of "whether they have really taken the medicine".

[0023] By not restricting users' freedom to pick up their medications, the dignity and self-care abilities of the elderly are protected, resulting in a better user experience.

[0024] It provides an effective technological tool for addressing the widespread social problem of "superstitious drug use" among the elderly, and helps to improve overall public health.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Embodiment 1 of this utility model is an intelligent medicine box with drug verification and self-service dispensing functions, such as... Figures 1 to 5 As shown, the system includes a smart pillbox terminal 2, a family management terminal 3, and a cloud platform 1. The smart pillbox terminal 2 is placed at home and is a hardware device directly operated by the elderly. The family management terminal 3 is a mobile app or WeChat mini-program for children or caregivers. Medication administration times can be set on the family management terminal 3 and uploaded to the cloud platform 1. The cloud platform 1 then transmits the medication administration times to the smart pillbox terminal 2, which reminds the patient to take their medication. The cloud platform 1 is responsible for data transfer and database verification.

[0030] The smart pillbox terminal 2 includes a pillbox body 4, a drug identification module, a drug dispensing verification module, a control module 17, a communication module 18 (which can be a WIFI module, such as ESP32-S), a human-computer interaction module, and a power module 25.

[0031] The main body 4 of the medicine box is rectangular, with a central intelligent control area 5 in the middle. Multiple medicine storage slots 6 are symmetrically distributed on both sides of the central intelligent control area 5 for placing medicine containers. The openings of the medicine storage slots 6 face upwards, and medicine containers 7 are placed inside the medicine storage slots 6. The shape of the medicine container 7 is a rectangular box that matches the inner cavity of the medicine storage slot 6, with its opening facing upwards. A flip-top 8 is provided at the opening of the medicine storage slot 6 to close the medicine container 7.

[0032] The drug identification module is integrated into the medicine box body 4, including an NFC reader chip 9 (such as PN5180), a QR code scanning camera 10 (such as a 5-megapixel fixed-focus miniature camera), and an auxiliary camera 11 for OCR text recognition. The drug identification module is electrically connected to the control module 17. The drug identification module is located in the central intelligent control area 5 of the medicine box body 4, on the front surface of the central intelligent control area 5.

[0033] When a user adds medicine to the smart pillbox terminal 2, it first attempts to obtain the electronic supervision code of the medicine through the NFC reading chip 9. If this fails, the QR code scanning camera 10 is activated to scan the code. If this also fails, the auxiliary camera 11 is used to photograph the medicine packaging, and the integrated OCR text technology is used to identify the generic name of the medicine. The medicine information obtained by the pill recognition module is processed by the control module and sent to the communication module 18. The communication module then sends the information to the cloud platform 1 for comparison and verification with the built-in national drug database. If the verification indicates "superstitious drug use" or counterfeit or substandard medicine, the cloud platform 1 sends a message to the control module 17 through the communication module 18 to trigger the alarm mechanism. The voice broadcaster 19 on the smart box 4 issues a "risky medicine" prompt and flashes the indicator light 20 as a reminder. At the same time, the cloud platform 1 sends a signal to the family management terminal 3.

[0034] The medication verification module includes a high-precision medication compartment pressure sensor 12 and a platform pressure sensor 14 installed below each individual medication compartment. A medication compartment placement platform 13 is located at the bottom of the medication compartment placement slot 6, and medication compartments 7 are placed on the platform 13. The platform 13 integrates a medication compartment pressure sensor 12 to detect changes in the weight of the medication compartments 7. A central verification platform 15 is located on the upper surface of the central intelligent control area 5. A high-precision platform pressure sensor 14 is integrated inside the central verification platform 15 to detect the weight of the medications placed on it.

[0035] To further confirm the accuracy of the medication taken, a recognition camera 16 is installed above the central verification platform 15 to take pictures of the pills to be taken on the central verification platform 15 and transmit the pictures to the control module 17 for analysis and judgment.

[0036] At the preset medication time on the smart pillbox terminal 2, the terminal clearly announces the name and quantity of the required medication via voice announcer 19 (e.g., "Please take 2 antihypertensive tablets and 1 hypoglycemic tablet"). When a person approaches, the indicator light 20 of the corresponding medication compartment lights up or flashes. Guided by the voice announcer 19 and indicator light 20, the user opens the corresponding medication compartment 7, takes out the specified number of medications, and places them all on the central verification platform 15. The control module 17 comprehensively compares the weight reduction of the medicine compartment 7, the weight increase of the central verification platform 15, and the drug characteristic data identified by the edge AI computing chip to determine whether the type and quantity of medicine are correct. Finally, based on the verification results, the control module 17 issues a confirmation prompt (prompting "You can take it" via the voice broadcaster 19) and generates a reliable record if successful. If it fails, it immediately triggers an audible and visual alarm (including a "Stop taking it" alarm from the voice broadcaster 19 and flashing of all indicator lights 20 on the medicine box body 4) and uploads it to the cloud platform 1 to notify the family management terminal 3, thereby ensuring the accuracy of each medicine dispensing while respecting the elderly's autonomy.

[0037] The control module 17 uses a low-power MCU as its core controller, additionally integrates an edge AI computing chip, and connects to a clock circuit, memory, and power management chip. In this embodiment, a low-power 32-bit ARM Cortex-M series MCU (such as the STM32L4 series) is used as the core controller, which is connected to an edge AI computing chip (such as the Canaan K210) via an SPI interface for local visual processing and recognition of photos taken by the camera 16.

[0038] The MCU is responsible for processing data from the drug identification module, pressure sensors (including the drug compartment pressure sensor 12 and the platform pressure sensor 14, which can be a weighing sensor driven by an HX711 chip), and the identification camera 16. It also controls the voice announcer 19, indicator lights 20, and communication module 18, while receiving data from the communication module 18. The images captured by the identification camera 16 are processed and identified by an edge AI computing chip. A power management chip (such as TI's BQ25619) dynamically adjusts the power consumption of each module based on the status of the smart pillbox terminal 2. The various components of the smart pillbox terminal 2 typically operate at low power, only operating in normal mode during medication administration and when a person is near the device, thus achieving ultra-long battery life. All critical medication administration events and drug verification records generate data packets, which are sent to the cloud platform 1 via the communication module 18 for blockchain storage.

[0039] The human-computer interaction module includes a voice announcer 19, indicator lights 20, ambient lighting 22, an infrared sensor 21, a display screen 24, and an infrared proximity sensor 23. The voice announcer 19 is located on the front surface of the central intelligent control area 5 to remind the patient to take medication. An indicator light 20 is located on the body 4 of each medicine compartment 7 near its corresponding flip cover 8; the indicator light 20 illuminates when medication needs to be taken from that compartment 7. An ambient lighting 22 and an infrared sensor 21 are located inside and above the medicine compartment in the medicine compartment placement slot 6. When the flip cover on the medicine compartment placement slot 6 is opened, the infrared sensor 21 senses the patient and controls the ambient lighting 22, allowing the patient to see the medication inside the medicine compartment 7 for easy removal. In addition, the infrared sensor 21 transmits the operation record of opening the flip cover to the control module 17, which, in conjunction with the pressure sensor and the recognition camera 16, records the medication administration, preventing errors. In other embodiments, the infrared sensor 21 can be integrated into the ambient lighting 22. The display screen 24 is located on the upper surface of the central intelligent control area 5 to display information about the medication to be taken. The human-computer interaction module also includes an infrared proximity sensor 23 or an accelerometer located in the central intelligent control area. If an infrared proximity sensor 23 is used, the control module 17 is triggered when a person approaches, causing the smart pillbox terminal 2 to enter the working state. If an accelerometer is used, the accelerometer senses the vibration caused by the person touching or picking up the smart pillbox terminal 2, thereby sending a signal to the control module 17 to cause the smart pillbox terminal 2 to enter the working state. When the medication time arrives, the control module 17 first controls the voice broadcaster 19 to issue a reminder, and the smart pillbox terminal 2 enters the working state when a person approaches or picks up the smart pillbox terminal 2.

[0040] In this embodiment, the power module 25 uses a removable high-capacity lithium battery, such as a 5000mAh lithium battery. The power management chip dynamically adjusts the voltage of each module. In standby mode, the smart pillbox terminal 2 only maintains the MCU's sleep timer and clock circuit, shutting down all peripherals, thereby achieving an ultra-long battery life of up to 30 days. The pillbox body 4 is equipped with a charging interface 26 and a lithium battery cover. The lithium battery can be charged through the charging interface 26, or the lithium battery cover can be removed to replace the lithium battery. In other embodiments, a solar panel can be installed on the upper surface of the pillbox body 4, and the solar panel can replenish the lithium battery through an interface connected to the lithium battery.

[0041] When a person is detected by the infrared proximity sensor 23 or accelerometer, the control module 17 automatically activates the drug identification module. The user brings the electronic regulatory code on the drug packaging close to the drug identification module, first attempting to read it by bringing it close to the NFC reader chip 9. If successful, the acquired code is sent to the cloud platform 1 via the communication module. If there is no NFC tag on the drug packaging, the QR code scanning camera 10 is used to scan and upload the drug barcode or QR code. If all the above methods fail, the control module 17 issues a reminder via the voice broadcaster 19, guiding the user to use the auxiliary camera 11 to photograph the front of the medicine box, extract the "generic name of the drug" text information through the control module 17, and upload it. The cloud platform 1 compares the received information with the national drug database and sends the verification result ("approved drug" or "risk drug") to the smart pillbox terminal 2 and the family management terminal 3. If it is a "risk drug", the voice broadcaster 19 of the smart pillbox terminal will continuously play a warning: "Uncertified drug detected, family members have been notified, please do not take it!" At the same time, the family management terminal 3 will receive an emergency push and can immediately initiate a video call.

[0042] When the preset medication time arrives at the smart pillbox terminal 2, the terminal announces "Medication time is up" via voice broadcast 19. As the elderly person approaches to retrieve the medication, the infrared proximity sensor 23 is triggered, sending a signal to the MCU, and the smart pillbox terminal 2 enters working mode, with indicator light 20 flashing. Guided by the voice and indicator light 20, the elderly person opens the corresponding medication compartment 7, retrieves the specified quantity of medication, and places it all into the central verification platform 15. High-precision pressure sensors at the bottom of the medication compartment 7 and in the central intelligent control area 5 detect changes in the corresponding medication. When the total weight decrease detected by the pressure sensor 12 in the medication compartment equals the weight of the current medication dose, and the total weight detected by the platform pressure sensor 14 also equals the weight of the current medication dose, and the recognition camera 16 instantly captures an image of the medication on the central verification platform 15, the edge AI computing chip running locally analyzes the appearance characteristics of the medication (such as shape, color, size, and markings). If there are no errors, a "Medication correct" reminder is sent to the patient; if there are errors, the patient is reminded to retrieve the medication again, and the system checks and sends information to the family management terminal.

[0043] In this embodiment, the medicine storage slot 6 and the corresponding medicine storage 7, flip cover 8, medicine storage pressure sensor 12, medicine storage platform 13, indicator light 20, infrared sensor 21, and ambient light 22 can be set as needed. In this embodiment, six are set and symmetrically distributed on both sides of the central intelligent control area 5.

[0044] When the drug is placed in the drug compartment 7 after being identified, the control module 17 selects a drug compartment and causes the indicator light 20 corresponding to the drug compartment 7 to flash, prompting the drug to be placed in the drug compartment 7. The control module records the position of the drug in the drug compartment.

[0045] The operation of this smart pillbox can begin with identity verification upon drug receipt, continue throughout the sensing and recording of each medication administration action, and culminate in reliable data storage and remote synchronization, forming a complete closed loop for medication safety. The beneficial effects of this invention include, but are not limited to: Through a three-tiered drug identification system consisting of an NFC reader chip (9+), a QR code scanning camera (10+), and an auxiliary camera (11), and by connecting with a national database, various drugs can be fully identified. This achieves a fundamental shift from "passive drug distribution" to "active interception," cutting off the circulation path of superstitious drug use and counterfeit drugs at the source.

[0046] By using infrared sensor 21, pressure sensor and edge AI computing chip, the verification of medication behavior is upgraded from simple "opening the lid" to closed-loop verification of "action + vision", which greatly reduces the error rate of missed doses and multiple doses, and the verification accuracy is significantly higher than that of a single sensor.

[0047] It greatly reduces the learning cost for the elderly, the automatic drug identification simplifies the medication dispensing process, and the voice broadcaster 19 and indicator light 20 are user-friendly, making it easier for the elderly to operate independently.

[0048] It significantly reduces the monitoring burden on family members. Reliable real-time alerts and medication reports allow family members to accurately grasp the elderly person's medication situation, eliminating the anxiety of "whether they have really taken the medicine".

[0049] By not restricting users' freedom to pick up their medications, the dignity and self-care abilities of the elderly are protected, resulting in a better user experience.

[0050] It provides an effective technological tool for addressing the widespread social problem of "superstitious drug use" among the elderly, and helps to improve overall public health.

[0051] This invention overcomes the shortcomings of existing smart pillbox technology, providing a completely new smart pillbox. Its core purpose is not simply to remind users to take medication or automatically dispense medication, but to eliminate medication safety risks caused by "superstitious medication use" and "uncontrolled medication behavior" at the source. Specifically, this invention solves the following technical problems existing in the prior art: (1) Solving the problem of drug access safety: Existing medicine boxes cannot identify and intercept uncertified folk remedies, health products and other "superstitious medicines". This utility model aims to provide a drug identity verification mechanism to ensure that only safe and compliant medicines can be taken.

[0052] (2) Solving the problem of inaccurate verification of medication behavior: Existing medicine boxes only detect medication by opening the lid, which cannot prevent "missed doses, overdose, or wrong doses". This utility model uses multi-sensor fusion technology to verify "whether the correct dose has been taken" with high confidence.

[0053] (3) Solving the problem of drug dispensing reliability: Existing mechanical drug dispensing structures are prone to drug jamming and wear. This utility model improves overall reliability by optimizing the structural design and replacing the purely mechanical dispensing method with an autonomous drug dispensing and verification process.

[0054] This invention relates to a second embodiment of an intelligent medicine box with drug verification and self-service dispensing functions. This embodiment aims to illustrate that, without departing from the basic functions of this invention, the configuration can be simplified to adapt to different market costs and demands.

[0055] To simplify the drug identification module, the NFC reader chip 9 and the auxiliary camera 11 for OCR text recognition can be removed, leaving only the QR code scanning camera 10 as the sole automatic identification method. For drugs without QR codes, manual input via the family management terminal 3 is required. The smart pillbox terminal 2 will still compare the manually entered drug name with the risk drug keyword database of the cloud platform 1 to achieve a basic "superstitious drug use" filtering function.

[0056] To simplify the supporting verification module, the expensive edge AI computing chip and recognition camera 16 have been eliminated. The system is now simplified to use an infrared sensor 21 to trigger a reaction and a pressure sensor to detect weight changes. When both conditions are met simultaneously, it is determined that the medication has been taken correctly, but the confidence level is recorded as "moderate." Simultaneously, a physical confirmation button is added to the top of the central intelligent control area 5 of the medicine box body 4. This physical confirmation button is electrically connected to the control module 17. After taking the medication, the elderly person can press the physical confirmation button, which sends a signal to the control module 17. The control module 17 then marks this record as "high confidence" and uploads it.

[0057] This invention relates to a third embodiment of a smart pillbox with drug verification and self-service dispensing functions. This embodiment is optimized for special environments such as mountainous and rural areas where network signals are unstable or nonexistent. A local "high-risk drug keyword database" and a "common drug approval database" are pre-loaded into the memory of the smart pillbox terminal 2. When there is no network, the drug names identified by OCR will be compared against the local database, still achieving the function of blocking most "superstitious drug use" and operating independently of the cloud platform 1.

[0058] The aforementioned identification and usage records are temporarily stored in local storage. Once network recovery is detected, the backlog of records will be automatically synchronized to cloud platform 1.

[0059] In this embodiment, a low-power 4G Cat.1 communication module is integrated as a backup link on top of the Wi-Fi communication module. When the Wi-Fi connection fails, it automatically switches to the 4G network for data transmission.

[0060] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
