1. What is a brain oxygen saturation monitor?

The brain oxygen saturation monitor, also known as the brain oxygen saturation monitor, is an instrument that uses near-infrared spectroscopy to measure local brain oxygen saturation. The brain oxygen saturation monitor can non-invasively and continuously measure the brain blood oxygen value, and directly reflect the changes in the balance of blood oxygen supply and demand in the patient's brain. It is an important medical device in clinical practice.

2. Working principle of brain oxygen saturation monitor

The brain oxygen saturation monitor is mainly composed of a host, a sensor, a signal amplifier, a connecting line, a power cord, etc. The brain oxygen saturation monitor is based on the Mie theory and the Lambert-Beer law. It uses the released near-infrared light to detect the local brain. Due to the difference in the light absorption coefficient of hemoglobin and oxygenated hemoglobin, the sensor attached to the patient's head is used to measure the near-infrared light scattering value and absorption value passing through the head to obtain the local brain oxygen saturation.

3. Importance of brain oxygen saturation monitor

The brain is a high-level nervous system with vigorous oxygen metabolism and high oxygen consumption. Maintaining normal brain oxygen metabolism is the primary link to ensure the normal function of brain function. Brain blood oxygen saturation reflects the percentage of brain tissue oxygen consumption and oxygen supply, and is one of the key indicators of normal brain function. If the brain blood oxygen saturation is low, it may cause brain hypoxia. Long-term brain hypoxia will cause irreversible brain damage and even brain death, and timely intervention measures need to be taken. Therefore, the role of brain oxygen saturation monitor is important.

Brain oxygen saturation monitor has the advantages of non-invasive, sensitive response, rapid real-time monitoring, and easy operation. It can realize continuous monitoring of local brain blood oxygen saturation and provide trend monitoring. It can be used for patients with reduced local brain blood flow, patients with local brain ischemia without blood flow, and perioperative high-risk patients. It is suitable for newborns, infants, and adults. It has important application value in clinical practice and can be used in multiple departments such as neurosurgery, cardiothoracic and vascular surgery, orthopedics, pediatrics, anesthesia, and ICU.

4. Development of China's brain oxygen saturation monitor market

China has a large population and is aging. Coupled with changes in living and eating habits, the number of patients with cardiovascular and cerebrovascular diseases in my country is increasing. Benefiting from the improvement of residents' income level, enhanced health awareness, and increased willingness to spend on medical expenses, the proportion of patients with cardiovascular and cerebrovascular diseases in China who undergo surgery continues to rise. Under this circumstance, it is extremely important to monitor the balance of oxygen supply and consumption in the brain, so there is a large room for development in my country's brain oxygen saturation monitor market.

Globally, the leading brain oxygen saturation monitor manufacturers include Medtronic, Philips Healthcare, GE Healthcare, Honeywell, Abbott, Boston Scientific, Masimo, Ornim Medical, Omron Healthcare, etc.

China's brain oxygen saturation monitor industry started late, and the domestic market is mainly monopolized by foreign companies. The high price of imported products is not conducive to its market penetration. In recent years, China's independent research and development capabilities for cerebral oxygen saturation monitors have gradually increased, and domestic products have gradually entered the market. In the long run, the localization rate of China's cerebral oxygen saturation monitor market is expected to increase in the future.
