With the rapid advancement of intelligent and portable medical devices, Bluetooth technology is increasingly applied in ventilators. By enabling wireless connections between devices, Bluetooth modules provide functions such as data transmission, remote control, and device management, significantly enhancing the convenience and intelligence of ventilators.
I. Features and Functions of the Solution
1. Real-Time Data Transmission and Monitoring
Ventilator sensors collect patient respiratory data (e.g., airflow, pressure, and respiratory rate), which the Bluetooth module transmits in real-time to mobile devices or computers.
• Features: Utilizes Bluetooth Low Energy (BLE) technology to ensure stable and low-latency transmission.
• Applications: Medical staff can monitor patients’ respiratory status anytime via mobile phones or tablets, improving medical efficiency.
2. Remote Parameter Adjustment
The Bluetooth module allows remote adjustments to ventilator parameters (e.g., pressure modes, oxygen concentration) to meet personalized needs.
• Features: Users can configure devices via a dedicated app, eliminating cumbersome manual operations.
• Applications: Portable home ventilators enable patients or caregivers to adjust parameters easily, improving the user experience.
3. Data Storage and Analysis
The Bluetooth module uploads data to mobile devices and stores it in the cloud for analysis, generating patient health reports.
• Features: Supports encrypted data transmission to ensure patient privacy and security.
• Applications: Doctors can use historical data to track long-term patient conditions and inform subsequent treatment plans.
4. Fault Diagnosis and Firmware Updates
The Bluetooth module supports remote diagnostics and firmware updates, simplifying maintenance procedures.
• Features: Supports OTA (Over-the-Air) updates for fast firmware upgrades via Bluetooth.
• Applications: In case of device malfunctions, fault information can be transmitted to the technical support platform, reducing repair times.
5. Multi-Device Connectivity and Centralized Management
In medical environments, Bluetooth modules enable multiple ventilators to connect to a single control device for centralized management.
• Features: Supports multi-device Bluetooth connectivity and unified data management.
• Applications: Medical staff can monitor the respiratory status of multiple patients in real-time from a single terminal, improving management efficiency.
