Description

Technical Field

[0001] This invention relates to the field of wearable medical monitoring devices, specifically to a wearable monitor alarm and visual wristband system based on the Internet of Things. Background Technology

[0002] With the rapid development of medical technology, patient monitors have been widely used in clinical diagnosis and treatment. They can monitor patients' vital signs in real time and accurately, such as heart rate, blood pressure, and blood oxygen saturation, providing important information for medical staff to understand changes in patients' conditions. However, existing monitoring equipment and technologies still have many shortcomings in practical applications, as follows:

[0003] (I) Limitations of traditional patient monitors

[0004] Delayed alarm response: Traditional monitors typically rely on sound or screen alerts for alarms, a method with significant drawbacks. In clinical settings, medical staff are often busy, managing multiple patients simultaneously, and the ward environment can be noisy. This can lead to staff missing the opportunity to respond to alarms due to not hearing them or seeing them on screen, thus delaying crucial patient care.

[0005] Limited mobility for medical staff: Traditional patient monitors are mostly fixed devices, installed in specific locations such as operating rooms, intensive care units, and emergency observation rooms. To observe changes in patients' vital signs, medical staff need to periodically check on or monitor them at the bedside or operating table. This not only increases their workload but also restricts their movement, hindering other medical and nursing activities and reducing overall medical efficiency.

[0006] Low efficiency in alarm information transmission: Traditional monitors only display alarm information on the monitor's main unit or on a screen in the ward, relying on active observation by medical staff. When medical staff are busy, it is difficult to ensure that alarm information for every patient is detected in a timely manner, easily leading to response delays. Furthermore, the monitoring equipment does not have complete data integration with the hospital information system (HIS), requiring alarm information to be relayed manually, further delaying treatment time.

[0007] (II) Shortcomings of existing monitoring wristbands

[0008] Limited Monitoring Parameters: Most existing monitoring wristbands on the market can only monitor a single parameter, such as heart rate or blood oxygen saturation. In clinical medicine, patients' vital signs are complex and variable. Monitoring a single parameter cannot comprehensively reflect the patient's condition, lacks multimodal data fusion and analysis capabilities, and cannot meet the diverse needs of clinical medical diagnosis.

[0009] Insufficient measurement accuracy: Some monitoring wristbands achieve non-invasive monitoring through optical sensors (such as PPG for blood oxygen and heart rate) and flexible electrodes. However, these optical sensors are susceptible to interference from factors such as motion artifacts, skin color, and ambient light, which may result in lower measurement accuracy than traditional monitors (such as ECG and invasive blood pressure monitors). This makes it impossible to provide accurate data support for clinical practice and affects the accuracy of medical decisions.

[0010] Unstable data transmission: Existing monitoring wristbands typically use Bluetooth Low Energy (BLE) or Wi-Fi for data transmission, but these transmission methods have problems such as short transmission distance and susceptibility to environmental interference, resulting in untimely data synchronization. Medical staff cannot obtain patients' vital signs information in real time, affecting the timely judgment and treatment of patients' conditions.

[0011] Low data security: Most existing monitoring wristbands do not use encrypted communication protocols, making it easy for patients' health data to be stolen during transmission, posing a risk of data leakage and seriously threatening patients' privacy and security.

[0012] In conclusion, traditional patient monitors and existing monitoring wristbands have significant limitations in clinical use and cannot meet the demands of modern medicine for efficient, accurate, and safe monitoring. Therefore, developing a new monitoring device that can overcome these shortcomings is of great practical significance. Summary of the Invention

The data gateway can also transmit intranet data to the external network via a mobile server, enabling the alarm visual wristband to obtain real-time content display and proactive alarm prompts from the operating room monitor provided by the hospital's data center or cloud through the external network.

First, a reverse proxy server is configured in the DMZ area to expose HTTPS / 443 port to the outside world. Then, a data distribution service is established. The latency in the direct connection mode of the internal network is ≤200ms, and the external network relay mode is implemented through MQTT over TLS. Finally, the TimescaleDB streaming database is deployed to store the monitoring data of the most recent 24 hours.

[0062] Example 7

[0063] like Figures 1 to 4 As shown, this embodiment provides a specific implementation method for the security and compliance configuration of this system.
