Description

Technical Field

[0001] The present invention relates to the technical field of Internet of Things, and in particular to an intelligent time-sharing medicine box, an intelligent medicine dispensing system and an intelligent medicine dispensing method, an electronic device and a computer-readable storage medium for inpatients with diabetes based on the Internet of Things. Background Art

[0002] Smart medicine boxes or smart medication boxes for diabetic inpatients can facilitate the medication use of diabetic inpatients. Drugs such as insulin can be stored in these smart medicine boxes in advance, and diabetic inpatients can be reminded to take their medicines on time. For example, the utility model patent with patent number CN221490780U discloses a portable smart medication box for diabetic patients, as shown in the attached figure. Figure 1 As shown, the medicine box includes a medicine storage box 1 and a reminder device 8 fixedly connected to one side of the medicine storage box 1. A partition structure is provided inside the medicine storage box 1. The partition structure includes a plurality of vertical plates 2. A plurality of horizontal plates 3 are evenly spaced and fixedly connected to one side of the vertical plates 2. An adjustment structure is provided on the side of the horizontal plate 3 away from the vertical plates 2. The adjustment structure includes a plurality of storage sleeves 4. A fixing structure for fixing the position of the vertical plates 2 is provided on the top of the medicine storage box 1 and close to the back side. The inner space is separated by the corresponding horizontal plates and vertical plates in the partition structure provided in the medicine storage box, and the extension distance of the horizontal plate is adjusted by using the storage sleeve in the adjustment structure provided on the horizontal plate. At the same time, the position of the vertical plate can be fixed by using the fixed structure after the adjustment is completed, so as to avoid the inconvenience of drug placement caused by the fixed setting of the partition space.

[0003] Although the above-mentioned smart medication box for diabetics can separate and store medicines through partitioned spaces and provide medication reminders, it still has the following inconveniences in actual use: Existing medicine boxes only allow nurses to pre-assess and store a certain amount of medication in the box according to its capacity. They cannot automatically generate the required medication amount based on the patient's hospitalization status and condition recorded in the patient's electronic medical record. The medicine box lacks automated dispensing capabilities. The existing smart medication boxes for diabetics, after being placed in the ward by nurses, only remind patients to pick up their medicines on time at the beginning. They are unable to follow up the entire process and detect whether the patients have taken their medicines in place. Therefore, there is no way to monitor the patients' medication-taking actions in real time and effectively. If nurses monitor the entire process, it will undoubtedly take up a lot of nursing resources. Therefore, there is no intelligent monitoring function for patients' medication-taking actions and a lack of a medication management system. Summary of the Invention

[0039] 2. System Application Implementation Process 1. Medical order data processing stage The hospital's HIS system generates a structured medication plan: a 5-minute tolerance window is set for time accuracy, and dosage specifications are accurate to 0.1 unit (insulin); For example, you can generate the following JSON format corresponding to different time-slot instructions for pre-stored information: { "patientID": "DM202311001", "schedule": [ { "timeWindow": "07:00-07:15", "drug": "Insulin Aspart", "dose": "12U", "storageTemp": "2-8℃" }, { "timeWindow": "12:45-13:00", "drug": "metformin", "dose": "0.5g", "storageTemp": "normal temperature" } ] }. The above time-division instructions can be sent to the nurse's PDA, allowing them to prepare the medicine in advance and store it in time-series medicine storage boxes with different attributes (configured time periods). They can also be sent to an automatic medicine loading robot, allowing the robot to execute the corresponding time-division instructions, automatically pre-stock the medicine in the corresponding medicine storage box in the patient's intelligent time-division medicine box, and deliver it to the bed. The specific combination of robots (medication packaging robots, transport robots) to achieve the above-mentioned automatic medicine packaging and delivery functions can be implemented in combination with robot control technology. For example: (1) Robot control system of the backend server Connect to the hospital HIS system to obtain medical order data; Generate drug packaging instructions with timestamps (see above description); The instructions are transmitted to the packaging robot control terminal via the 5G private network.

[0040] (2) Intelligent packaging robot system Equipped with a visual recognition robotic arm (to identify drug shape / color / barcode); Connect to automatic medicine cabinet to obtain prescription drugs; Pack into four-compartment medicine storage boxes according to time sequence (morning / noon / evening / before bed); Built-in NFC chip to write patient ID + medication time; After the subpackaging is completed, the transport robot signal is triggered.

[0046] 2.3 Drug loading verification (1) After the nurse places the medicine, the weight sensor automatically calibrates: Baseline value = current reading - theoretical drug weight.

[0047] (2) The system performs two-factor authentication: Weight deviation ≤±5%; Temperature compliance ±1℃; (3) Abnormal situations trigger three-level warnings: Yellow warning: 1 verification failed; Orange warning: 2 consecutive failures; Red alert: 3 consecutive failures.

[0048] 3. Patient medication collection process 3.1 Identity Authentication Phase (1) The patient touches the fingerprint sensor, and the FPC1020A collects ≥12 feature points (minutiae); (2) Generate a 256-bit feature hash value and upload it to the server via NB-IoT; (3) The ArcSoft algorithm takes less than 800ms to compare and returns a confidence value; 3.2 Unlock control logic is as follows: Fingerprint verification passed + time window valid: unlock immediately; Fingerprint passed + time window expired: vibration prompt + LED flashes red; Fingerprint failed + Time window valid: lock and try again after 1 minute.

[0049] 3.3 Monitoring of medication taking behavior (1) Capacitive sensor detects human hand contact (threshold > 200fF); (2) Weight sensor records dynamic change curve: Within 10 seconds after unlocking, there should be a weight change of ≥50g (total weight of the medicine in the medicine storage box); The remaining weight after drug dispensing is completed is ≤ the preset drug weight × 10%.

[0050] If the above conditions are met, the medicine can be taken effectively.

[0051] 3.4 Data reporting mechanism (1) Immediate reporting of incidents: Biometric data (per verification attempt); Abnormal unlocking events; Temperature exceeding limit alarm (default).

[0052] (2) Periodic reporting of data: Battery status (hourly); Historical medication records (every 6 hours); Equipment self-test report (00:00 every day).

[0054] 4.2 Warning Process (1) Failure to collect medication on time: First timeout: PDA pushes reminder to responsible nurse; 15 minutes timeout: activate the ward call system; 30 minutes timeout: Generate a doctor's notice.

[0055] (2) Temperature abnormality handling: If the limit is exceeded for 1 hour continuously: the backup medicine storage box is activated; Temperature > 8°C for 2 hours: Perform drug effectiveness assessment.

[0056] 5. Maintenance management module 5.1 Equipment Self-Test Procedure Executed at 03:00 daily: Electromagnetic lock actuation test (3 cycles); Sensor benchmark calibration; Memory bad block detection.

[0058] Therefore, based on the above implementation, the required medication amount can be automatically and adaptively generated based on the patient's hospitalization status and condition as recorded in the patient's electronic medical record, thereby improving the rationality of medication dispensing and avoiding waste caused by nurses' blind medication dispensing. Furthermore, by integrating biometric recognition with Internet of Things technology, the present invention reduces the medication error rate compared to traditional pill boxes and can fully monitor the patient's medication collection process, saving nursing resources, strengthening the implementation of medication management systems for hospitalized diabetic patients, and realizing intelligent medication management.
