This design delivers a strong and safe framework for constructing superior related medical units, serving to speed up regulatory approval with pre-configured design documentation templates.
The Safe Telehealth Reference Design is a complete distant affected person monitoring resolution designed to measure coronary heart charge, blood oxygen saturation ranges, and physique temperature. As a related, single-board system, it ensures safe and dependable knowledge transmission via AWS or Azure cloud connectivity. This enables medical professionals to remotely entry, analyze, and diagnose affected person knowledge in real-time, resulting in well timed and knowledgeable remedy selections. Moreover, the board helps Bluetooth connectivity, enabling direct entry to affected person knowledge with out requiring cloud integration.
This reference design by Microchip Know-how serves as a foundational structure for varied edge-to-cloud medical functions, together with telehealth very important signal monitoring, distant and stationary affected person monitoring, related drug supply methods resembling nebulizers and glucose meters, and built-in medical modules for imaging, surgical, and different healthcare units. The system integrates the WBZ350, a 32-bit Arm Cortex-M4F MCU module with Bluetooth Low Vitality (LE) 5.2 functionality, making certain environment friendly communication. Safety is enhanced with the ATECC608C {hardware} safety ingredient, offering safe authentication and encryption. Energy administration is dealt with by the MCP1640 and MCP1711 regulators, making certain vitality effectivity. Moreover, medical-grade sign conditioning and measurement expertise from ams OSRAM improve accuracy and reliability.
Key parts of this design embody the WBZ350PE-I, a globally licensed RF-ready multi-protocol MCU module that includes Bluetooth and Zigbee connectivity with superior safety and sturdy analog capabilities. The ATECC608C-TFLXTLSS-PROTO cryptographic co-processor ensures safe hardware-based key storage and integrates Elliptic Curve Diffie Hellman (ECDH) and Elliptic Curve Digital Signature Algorithm (ECDSA) for high-level encryption and authentication. The MCP1711T-18I/OT is a extremely environment friendly CMOS Low Dropout (LDO) regulator that delivers as much as 150 mA of present whereas consuming solely 0.6 μA of quiescent present. The MCP1640T-I/CHY, a high-efficiency synchronous step-up DC-DC converter, operates at 500 kHz and helps as much as 800 mA Isw, optimizing energy utilization.
The bio-signal and temperature sensors built-in into this reference design present correct well being monitoring capabilities. The AS7057A-BWLM bio-signal sensor analog front-end (AFE) detects photoplethysmogram (PPG) and pulse transit time (PTT) alerts to measure SpO2 and coronary heart charge. The SFH 7016 multi-chip LED emitter contains inexperienced (530 nm), crimson (655 nm), and infrared (940 nm) wavelengths for exact sign detection. The SFH 2201 and SFH 2704 silicon PIN photodiodes additional improve sensitivity for bio-signal monitoring.
To help improvement, Microchip gives instruments such because the PIC32CX-BZ3 and WBZ35x Curiosity Board, which facilitates the analysis of WBZ350 modules. The ATECC608 Belief Board permits safe authentication prototyping, whereas ams OSRAM gives analysis kits for bio-sensors and digital temperature sensors to streamline product improvement.
