Blood Oxygen Meter Scheme and Algorithm Program Based on XBLW‘s Operational Amplifier,Shift Register,and Darlington Transistor Array
The Blood Oxygen Meter Is A Medical Device Used To Measure The Oxygen Saturation Of Human Blood. It Works Non-Invasively By Placing A Sensor On The Fingertip, Where Infrared Light Is Used To Illuminate The Blood Vessels, Allowing Measurement Of The Light Absorption Characteristics Of Oxygenated And Deoxygenated Hemoglobin In The Blood To Determine Blood Oxygen Saturation.
1. Product Structure
The Blood Oxygen Meter Consists Of Two Main Parts: The Main Unit And The Sensor. The Main Unit Is Typically A Small Handheld Device That Integrates A Processor And A Display Screen To Process And Display The Measurement Results. One End Of The Sensor Is Connected To The Main Unit, While The Other End Is Placed On The Patient's Fingertip To Sense Changes In Light. The Sensor Transmits The Acquired Data To The Main Unit Through A Connecting Cable.
2. Working Principle
The Blood Oxygen Meter Utilizes An Infrared Light Source To Illuminate The Patient's Fingertip. As The Light Passes Through The Blood Vessels, It Is Absorbed By Oxygenated And Deoxygenated Hemoglobin In The Blood. The Sensor Detects Changes In The Intensity Of The Absorbed Light And Converts It Into Electrical Signals, Which Are Then Transmitted To The Main Unit. The Main Unit Processes These Signals To Calculate The Blood Oxygen Saturation Value And Displays The Results In Real-Time On The Screen.
3. Product Parameters
Visible Screen Type: OLED Blue-Yellow Dual-Color Visible Screen
Blood Oxygen Saturation: Measurement Range: 70%~100%, Accuracy: ±1%
Heart Rate: Measurement Range: 25 BPM~250 BPM, Accuracy: ±1 BPM
Perfusion Index: ≥0.3%, ±0.1%
Visible Screen Type: OLED Visible Screen
Manual Adjustment Of Interface Orientation: 6 Visible Modes, 4 Visible Directions
LED Display: Simultaneous Display Of Test Values And Bar Graphs
Low Battery Voltage Indicator
4. Solution Design
1. Hardware Component
2. Software Component
5. Application Field
The Blood Oxygen Meter Is Widely Used In Hospitals, Homes, Sports Training Facilities, And Other Scenarios. In Hospitals, It Is Commonly Utilized To Monitor Patients' Blood Oxygen Levels During Surgeries, Intensive Care, Anesthesia, And For Early Screening Of Cardiovascular And Pulmonary Diseases. In Homes, The Blood Oxygen Meter Helps Individuals Monitor Their Health In Real-Time, Especially Beneficial For Elderly People And Those With Acute Or Chronic Respiratory Conditions. In Sports Training Facilities, It Is Used To Monitor Athletes' Blood Oxygen Saturation To Assess Training Effectiveness And Adjust Training Intensity.
