A blood oxygen meter is an instrument used to measure pulse rate, blood oxygen concentration, and perfusion index. Blood oxygen concentration is one of the important basic data in clinical medicine. If conditions permit, people should constantly monitor their blood oxygen saturation, which is more beneficial for their health. The Tuyang Technology Blood Oximeter Solution, below is a detailed explanation of the knowledge.
1、 Development Principles of Household Blood Oximeter Solutions
Blood oxygen saturation should usually be above 95%, which is the normal level of the human body. When the concentration of blood oxygen in the blood is at a low level, it can affect the normal work of the heart and brain. Due to the different absorption abilities of red blood cells, oxygenated hemoglobin (HBO2) and reduced hemoglobin (HB) in the blood to red light (660nm) and infrared light (910nm). Reduced hemoglobin (HB) absorbs more red light and less infrared light. On the contrary, oxygenated hemoglobin (HBO2) absorbs less red light and more infrared light. The red LED and infrared LED lights are set at the same position on the nail oximeter. When light penetrates from one side of the finger to the other and is received by a photodiode, a corresponding proportion of voltage can be generated. After processing by the microcontroller, the output results are displayed on the LCD screen.
Tuyang Technology adopts a complete set of SPO2 pulse oximeter finger clamp terminal devices with Jerry's ultra-low power Bluetooth intelligent chip signal chain, power supply, and connection components. With the help of pulse oximeter AFE, it is possible to accelerate and simplify the pulse oximeter, ensuring the highest quality clinical measurements.
2、 Introduction to the Functions of Household Blood Oximeter Solutions
The home oximeter solution adopts AC6323A chip, packaged in QFN20, and is designed through microcontroller program development. Ultimately, the home oximeter can achieve the following functions:
(1) One click operation, instantly displaying detection results
(2) Automatic push out, no finger state automatic shutdown
(3) Data storage, automatic storage of data after measurement and production of data sheet records
(4) LED backlight display, clear and visible measurement results
The PCB structure diagram of the home oximeter developed by Tuyang Technology is fully compatible with other home oximeter male mold shells on the market. The PCB structure of the oximeter can also be customized according to customer requirements. The home oximeter PCB is a single panel, and the shape of the product can be designed and changed by oneself. Merchants can create more different shapes to meet market demand.
