Description

Technical Field

[0001] This invention relates to the field of medical information management technology, specifically to a critical value alarm management system and method based on a smart bracelet. Background Technology

[0002] Critical values ​​refer to test results that indicate a potential life-threatening situation for a patient. Clinical medical staff should provide timely and proactive intervention or treatment as needed. The critical value reporting and handling system establishes a management mechanism for reviewing, reporting, and recording test results that indicate a life-threatening situation to ensure patient safety. At least one clinical physician or nurse should confirm the critical value warning in the system within 10 minutes of its issuance. If neither physician nor nurse confirms within 10 minutes, a pop-up reminder will appear on the laboratory's computer, and laboratory staff must contact the relevant clinical department again by phone for confirmation. Other medical technology departments should immediately call the corresponding clinical department after issuing a critical value report in the system. After notifying the clinical department of the critical value information by phone, medical technology personnel must accurately record the notification time and the name and employee number of the person answering the phone in the system. Clinical medical staff should actively cooperate and proactively inform the other party of their employee number and name to ensure that responsibility is assigned to the appropriate person. However, clinical work is busy, and it is difficult for medical, nursing, and laboratory staff to be at the computer 24 hours a day. As a result, there are often cases where critical values ​​are not confirmed in time, which delays the identification of patients' conditions. There is an urgent need for a system that can enable medical staff to receive and process critical value alarms in a timely manner. Smart bracelets have potential in terms of portable information reception. Therefore, we propose a critical value alarm management system and method based on smart bracelets. Summary of the Invention

[0003] The purpose of this invention is to provide a critical value alarm management system and method based on a smart bracelet, which has the advantages of significantly shortening the time from alarm issuance to medical staff response and reducing the risk of delayed disease identification. It solves the problem that clinical staff are busy and it is difficult for medical, nursing and laboratory personnel to be at the computer 24 hours a day, which often results in the critical value being confirmed after a timeout, thus delaying the identification of the patient's condition.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a critical value alarm management system based on a smart bracelet, comprising a smart bracelet and a supporting management process; The smart bracelet includes a main control module, a sensor module, a communication module, an interaction and display module, a power management module, and a shell and structure module. The supporting management process includes setting the alarm range for critical values, integrating data into the cloud, pushing alarm information, receiving and reminding the bracelet, confirming critical values, and handling mechanisms for failure to confirm in a timely manner. The various modules of the smart bracelet work together to achieve the emergency alarm function: The main control module schedules the communication module via Bluetooth communication protocol, and coordinates the positioning data collected by the sensor module and the alarm commands received by the communication module to output critical value reminders in a coordinated interaction with the display module. The power management module provides stable power to each module, and the casing and structural modules are designed to be waterproof and shockproof to protect the operating environment of the modules.

[0005] Preferably, the main control module uses a low-power microprocessor and a domestically produced chip.

[0006] Preferably, the display screen of the interaction and display module is an OLED screen, which, together with the vibration motor, can effectively remind nursing staff to pay attention to critical value alarms in noisy medical environments.

[0007] Preferably, the lithium battery capacity of the power management module is adapted between 50-200mAh depending on the functional complexity, and the corresponding battery life is 7 to 30 days.

[0008] Preferably, in the outer shell and structural module of the smart bracelet, the outer shell is made of plastic to meet the requirements of strength and lightness, the strap is made of silicone to ensure a comfortable fit, and the waterproof structure meets the IP68 waterproof standard to meet the needs of daily handwashing.

[0009] A system-based critical value alarm management method includes the following steps: a. Establish the critical value alarm range for inspection and testing items, and clarify the threshold for each item corresponding to a life-threatening crisis state; b. Integrate inspection and testing data to the cloud and build a data aggregation platform; c. When the examination or test results exceed the threshold, they are automatically pushed to the smart bracelet worn by the nursing staff through the integrated system; d. The smart bracelet receives alarms through sensors, and through the collaboration of the communication module and the main control module, the interaction and display module presents the alarm information, and the vibration motor starts to remind the user; e. After receiving an alarm notification, nursing staff will confirm the critical value on the smart bracelet. If the confirmation is not made in time, the subsequent laboratory pop-up window and telephone notification mechanism will be triggered.

[0010] Preferably, in step a, the threshold values ​​for each life-threatening condition corresponding to each item need to be accurately determined in accordance with clinical diagnosis and treatment guidelines. The determined threshold values ​​are synchronized to the main control module of the smart bracelet through the hospital information system. The main control module has a built-in threshold verification algorithm to compare the test data with the threshold values ​​in real time, so as to accurately trigger the critical value alarm output of the interaction and display module.

[0011] Preferably, step b employs encrypted transmission to ensure data security, constructs a stable data aggregation platform, and this platform is compatible with the smart bracelet communication module to ensure that inspection and testing data can be smoothly transmitted to the smart bracelet, providing a reliable data foundation for subsequent alarm pushes.

[0012] Preferably, step c utilizes the compatibility between the smart bracelet communication module and the integrated system to ensure timely push notifications.

[0013] Preferably, the subsequent laboratory pop-up and telephone notification mechanism in step c refers to the following: if no confirmation is received from clinicians and nurses within 10 minutes, a pop-up reminder appears on the laboratory's work computer, and laboratory staff notifies the relevant clinical department again by telephone for confirmation. Other medical technology departments immediately call the corresponding clinical department after issuing a critical value on the reporting system, and medical technology personnel must accurately record the notification time and the name and employee number of the person answering the phone on the system.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention can improve the timeliness of critical value processing and reduce the risk of delays in treatment. Compared with the traditional model, where medical staff cannot monitor the computer 24 hours a day and often have problems with the timeout confirmation of critical values, this system uses a portable smart bracelet that can actively push alarm information. Combined with a vibration motor, it can effectively remind patients even in noisy medical environments, allowing medical staff to quickly receive and process alarms no matter where they are in the department. Combined with the clear requirement of confirmation within 10 minutes in the supporting process, the time from alarm issuance to medical staff response is greatly shortened, avoiding delays in patient condition identification and intervention due to information lag. 2. This invention ensures stable system operation and adapts to medical scenario requirements. At the hardware level, the main control module uses a low-power microprocessor and domestically produced chips, balancing data processing efficiency and power consumption. The lithium battery of the power management module is adapted to the function with a capacity of 50-200mAh, achieving a battery life of 7-30 days and meeting the requirement of 24-hour standby alarm reception. The shell and structural modules adopt a plastic shell, silicone strap and IP68 waterproof design, which not only meets the requirements of strength, portability and wearing comfort, but also adapts to the daily hand washing and liquid contact scenarios of medical staff, ensuring the stable operation of each module in the medical environment. 3. This invention can construct a closed-loop management system, enabling traceability of responsibility. The supporting management process forms a complete closed loop from "setting thresholds - data integration - alarm push - receiving reminders - confirming handling - supplementary notification for overdue cases". When setting thresholds, clinical guidelines are combined and synchronized to the wristband to ensure accurate alarms. Data integration uses encrypted transmission to ensure security. If confirmation is not timely, a mechanism is followed: a 10-minute timeout pop-up window - a telephone notification from the laboratory within 5 minutes - feedback from the clinic within 3 minutes. The notification time and the person receiving the call are recorded throughout the process, ensuring that responsibility is assigned to the person at each stage, facilitating traceability management. 4. This invention enhances data transmission reliability, balancing practicality and scalability. Encrypted transmission is used when data is integrated into the cloud to ensure the security of patient test data. The smart bracelet's communication module is compatible with the integrated system, ensuring timely alarm notifications. Furthermore, the use of domestically produced chips in the bracelet helps control costs and ensures a stable supply chain. The silicone strap improves wearing comfort. The overall design balances the specificities of the medical scenario with ease of operation, making it easily accepted by medical staff and facilitating its widespread application in hospitals at all levels.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-4 As shown, the present invention provides a technical solution: a critical value alarm management system based on a smart bracelet, including a smart bracelet and a supporting management process; The smart bracelet includes a main control module, a sensor module, a communication module, an interaction and display module, a power management module, and a shell and structure module. The supporting management process includes setting the alarm range for critical values, integrating data into the cloud, pushing alarm information, receiving and reminding the bracelet, confirming critical values, and handling mechanisms for failure to confirm in a timely manner. The various modules of the smart bracelet work together to achieve the emergency alarm function: The main control module schedules the communication module via Bluetooth communication protocol, and coordinates the positioning data collected by the sensor module and the alarm commands received by the communication module to output critical value reminders in a coordinated interaction with the display module. The power management module provides stable power to each module, and the casing and structural module are designed to be waterproof and shockproof to protect the module's operating environment. The main control module uses a low-power microprocessor and domestically produced chips. By optimizing the instruction scheduling algorithm, it reduces system power consumption while ensuring the real-time performance of multi-sensor data fusion and Bluetooth communication. This ensures the smart bracelet's battery life in scenarios of "continuous standby plus sudden alarm" and supports reliable reception of emergency alarms 24 / 7. The interactive and display module uses an OLED screen, which, together with a vibration motor, can effectively alert nursing staff to critical value alarms in noisy medical environments. Utilizing its clear display, low power consumption, and touch operation support, it can quickly and clearly display detailed information related to critical values, making it easy for nursing staff to obtain key information in a timely manner. The lithium battery capacity of the power management module is adapted between 50-200mAh depending on the complexity of the function, and the corresponding battery life is 7 to 30 days. This is to meet the needs of the smart bracelet to be in standby mode for a long time and to respond to emergency alarms in a timely manner, so as to avoid interruption of alarm information reception due to insufficient power. The smart bracelet's outer shell and structural modules are made of plastic to meet the requirements of strength and lightness, while the strap is made of silicone to ensure a comfortable fit. The waterproof structure meets the IP68 waterproof standard to meet the needs of daily handwashing scenarios, ensuring that all modules of the bracelet can operate normally during the daily work of medical staff and not affect the emergency alarm function.

[0018] It should be noted that there is not just one smart bracelet in each clinical department. When on duty, nursing staff need to log in with their employee ID number. Each smart bracelet corresponds to one or more patients (depending on the number of staff on duty and the number of patients). After get off work, nursing staff can log out with their employee ID number to change the wearer, or each medical staff member can wear one bracelet. Once the bracelet leaves the local area network, it will no longer receive signals.

[0019] A system-based critical value alarm management method includes the following steps: a. Establish the critical value alarm range for inspection and testing items, and clarify the threshold for each item corresponding to a life-threatening crisis state; b. Integrate inspection and testing data to the cloud and build a data aggregation platform; c. When the examination or test results exceed the threshold, they are automatically pushed to the smart bracelet worn by the nursing staff through the integrated system; d. The smart bracelet receives alarms through sensors, and through the collaboration of the communication module and the main control module, the interaction and display module presents the alarm information, and the vibration motor starts to remind the user; e. After receiving the alarm notification, nursing staff will confirm the critical value on the smart bracelet. If the confirmation is not made in time, the subsequent laboratory pop-up window and telephone notification mechanism will be triggered. In step a, it is necessary to combine clinical diagnosis and treatment guidelines to accurately define the threshold of life-threatening state corresponding to each item, and the defined threshold is synchronized to the main control module of the smart bracelet through the hospital information system. The main control module has a built-in threshold verification algorithm to compare the test data with the threshold in real time in order to accurately trigger the critical value alarm output of the interaction and display module. Step b employs encrypted transmission to ensure data security and builds a stable data aggregation platform. This platform is compatible with the smart bracelet's communication module, ensuring that inspection and testing data can be smoothly transmitted to the smart bracelet, providing a reliable data foundation for subsequent alarm pushes. Step c utilizes the compatibility between the smart bracelet communication module and the integrated system to ensure timely push notifications, enabling nursing staff to quickly receive alarm information. Preferably, the subsequent laboratory pop-up and telephone notification mechanism in step c refers to the following: if no confirmation is received from clinicians and nurses within 10 minutes, a pop-up reminder appears on the laboratory's work computer, and laboratory staff notifies the relevant clinical department again by telephone for confirmation. Other medical technology departments immediately call the corresponding clinical department after issuing the critical value on the reporting system, and medical technology personnel must accurately record the notification time and the name and employee number of the person answering the phone on the system.

[0020] This technical solution uses a domestically produced low-power microprocessor (such as the Huawei HiSilicon Hi3861 series) as the main control module. It supports multi-sensor data fusion and Bluetooth communication, and features low power consumption to meet the wristband's battery life requirements. The sensor module integrates a geomagnetic sensor (such as the QMC5883L) for auxiliary positioning, which is soldered to the corresponding position on the wristband's circuit board. The communication module uses a Bluetooth 5.0 or higher version BLE module (such as the CC2541), connected to the main control module via an SPI interface to ensure stable data synchronization and firmware upgrade functionality. The interaction and display module uses a 1.3-inch OLED touchscreen (240×240 resolution), which is attached to the front of the wristband's outer shell. The cover has a reserved window, and the vibration motor (10mm in diameter) is installed below the screen. It is connected to the main control module via an I2C interface to ensure a noticeable vibration when an alert is triggered. The power management module uses a 120mAh lithium battery, paired with a contact charging module (2-pin spring contacts) and a power management chip (such as TP4056). The chip is responsible for charging and discharging protection and voltage stabilization. The entire assembly is fixed to the back of the band's circuit board. The outer shell and structural modules are made of PC / ABS plastic injection molded shell, and the strap is made of medical-grade silicone material. It is connected to the outer shell through a buckle structure. During assembly, waterproof rubber rings are added to the screen edge and charging contacts to ensure that the overall system meets the IP68 waterproof standard. System debugging Power the wristband, test the power supply stability of each module, debug the pairing and data transmission between the Bluetooth module and the computer through dedicated software to ensure that the alarm command can be pushed from the computer to the wristband within 30 seconds, test the positioning accuracy of the geomagnetic sensor, mark the positions in various departments of the hospital, calibrate the sensor data, and control the positioning error within 1 meter. The firmware was burned to the main control module, the threshold verification algorithm was debugged, and critical values ​​of different test items (such as platelet count below 50×10⁻⁶) were simulated. 9 / L), test whether the wristband can accurately compare and trigger the alarm, debug the interactive interface, and ensure that the OLED screen can clearly display information such as the patient's name, department, critical value items and values, the touch operation is responsive, and the vibration motor can vibrate continuously for 3 seconds when the alarm is triggered. Deployment and operation of supporting management processes Preliminary preparation and threshold setting The hospital's clinical departments (such as internal medicine and surgery) and laboratory departments, based on the "Expert Consensus on Reporting and Management of Critical Values ​​in Clinical Laboratory Tests" and the hospital's past clinical data, define the critical value thresholds for each test and examination item, enter these thresholds into the Hospital Information Management System (HIS), and synchronize them to the main control module of the smart bracelet through the HIS. Data integration platform construction Build a cloud-based data aggregation platform (such as using Alibaba Cloud ECS server), connect the hospital's laboratory equipment system (such as biochemical analyzer, hematology analyzer) and HIS via the HL7FHIR protocol, set up an encrypted data transmission channel (using AES-256 encryption algorithm), test the stability of data transmission, simulate the laboratory equipment to generate test results, and ensure that the data can be integrated into the cloud platform within 1 minute, and that the platform can automatically compare the data with preset thresholds. Alarm push and handling process testing Simulated scenario: The testing equipment generates a patient's blood potassium level of 6.5 mmol / L (exceeding the threshold of 6.2 mmol / L). After the cloud platform recognizes this, it triggers an alarm and pushes the alarm information (including the patient's name, bed number, and blood potassium level of 6.5 mmol / L) to the smart bracelet of the patient's responsible nurse through the integrated system. Wristband Response: After receiving the information, the OLED screen of the nurse's wristband immediately lights up to display the alarm content, the vibration motor starts, and after seeing the reminder, the nurse checks the corresponding alarm content and enters their employee number to complete the confirmation of the critical value. The system automatically records the confirmation time. Timeout handling test: If the simulated nurse fails to confirm within 10 minutes, a pop-up reminder will appear on the laboratory computer at the 10-minute mark. Laboratory staff will then call the clinical department within 3 minutes. After the call is connected, the name and employee number of the nurse answering the call will be recorded. The nurse answering the call will respond within 2 minutes and will handle the matter immediately. The entire notification process will be recorded simultaneously.
