TRUSAT Oximeter Motherboard PN 6050-0006 for Pulse Oximeter Repair

Product Description

TRUSAT oximeter motherboard for oximeter spare parts Motherboard PN: 6050-0006

The **TRUSAT Oximeter Motherboard** is the **core printed circuit board (PCB) assembly** that powers and controls a **pulse oximeter** (SpO₂ monitor). While "TRUSAT" is not a widely recognized brand in the medical device industry (possibly a regional or OEM manufacturer), I’ll provide a **general technical breakdown** of a typical **pulse oximeter motherboard** based on industry standards.

### **Key Components & Functions of a Pulse Oximeter Motherboard**
1. **Microcontroller (MCU) / Processor**
- Manages **signal processing**, **SpO₂ calculations**, and **user interface**.
- Common chips: **ARM Cortex-M series**, **STMicroelectronics STM32**, or **NXP/Freescale**.

2. **Optical Sensor Interface**
- Connects to **LEDs (red & infrared)** and **photodiode** for light absorption measurement.
- Includes **analog front-end (AFE)** chips (e.g., **TI AFE4490**, **Maxim MAX30102**) for signal conditioning.

3. **Power Management**
- **Voltage regulators** (e.g., 3.3V/5V DC-DC converters).
- **Battery management** (Li-ion or AAA batteries) with low-power modes.

4. **Display & User Interface**
- Drives **OLED/LCD screen** (shows SpO₂%, pulse rate, waveform).
- Tactile buttons or touch-sensitive controls.

5. **Connectivity (Optional)**
- **Bluetooth/Wi-Fi modules** (e.g., **HC-05**, **ESP32**) for wireless data transmission.
- **USB/serial ports** for firmware updates or PC communication.

6. **Signal Processing & Algorithms**
- **Digital filters** to reduce motion artifacts/noise.
- **Proprietary SpO₂ algorithms** (e.g., Masimo SET®, Nellcor DS100).

7. **Safety & Compliance**
- **EMI shielding** to prevent interference.
- Meets **IEC 60601-1** (medical electrical safety) and **ISO 80601-2-61** (pulse oximetry standards).

### **Typical Specifications**
- **Input Voltage**: 3.7V (Li-ion) or 3V (AAA batteries).
- **Sampling Rate**: 100–1000 Hz (for accurate waveform detection).
- **Output**: SpO₂ (70–100% accuracy ±2%), pulse rate (30–250 BPM).
- **Compatibility**: Works with **finger/clip sensors** or disposable probes.

### **Applications**
- **Standalone pulse oximeters** (consumer or clinical grade).
- **Integrated into multi-parameter monitors** (e.g., Mindray devices).
- **Wearable health trackers** (smartwatches, fitness bands).
