The development history of pulse oximeter
1935: Matthes developed the world's first Spo2 measurement instrument using red and green filters.
1964: Shaw assembled the first 8-wavelength absolute reading children's oximeter produced by HP.
1949: Wood added a pressure piston to obtain absolute blood oxygen saturation.
1981:Traditional Blood Oxygen Technology. In 1972, Aoyagi invented the traditional pulse oximetry technology in Nihon Kohden. This technology estimates pulse oximetry by calculating the ratio of the pulsation component at the measurement location to the different absorption of red light and infrared light. Nellcor used this technology in Nellcor disposable spo2 sensors introduced in 1981.
1998: Masimo blood oxygen. In 1998, Diab & Kiani invented signal extraction spo2 technology in Masimo. By using a self-tuning filter with DST and parallel motors to isolate the arterial signal and noise, the oximeter still has accurate spo2 measurement under the condition of exercise and low perfusion. This technology was announced to the world in 1998.
Masimo Blood Oxygen Technology
It is developed based on traditional blood oxygen technology. Traditional blood oxygen is based on the pulse waveform and takes the venous noise and other noises as quantification (that is, the vein is considered non-fluctuating). Therefore, when the pulse waveform is irregular or fluctuating due to interference. (These types of interference are clinically unavoidable) will cause misreading on blood oxygen. Masimo blood oxygen technology solves these traditional blood oxygen defects, not based on pulse waveform and identifying venous fluctuations and classifying them as noise to measure the actual arterial blood oxygen value.
About Masimo Spo2 Technology
The Masimo SET Tech spo2 sensor can monitor pulse rate and oxygenation. The Rainbow spo2 sensor has additional non-invasive monitoring, including SpHb, SpCO, SpMet, and Pvi. The research indicates that the SET improves the ability to detect life-threatening events and reduces false alarms.
In 2012, Masimo received FDA 510(k) clearance for devices and sensors with labeling for screening newborns for CCHD. The World Health Organization called non-invasive hemoglobin an "innovative medical technology for cost-effectively addressing global health concerns and needs".
The Advantages of MASIMO blood oxygen Technology
With the world's top-level blood oxygen module
Gold standard
Realize the performance requirements of anti-sports and anti-weak perfusion.
The only one to pass the FDA certification in the case of weak perfusion and exercise
MASIMO is of great clinical significance-reducing the rate of medical error
(1) Reduced false alarm rate Masimo SET reduced the false alarm rate by 90%.
(2) Shortened response time | Masimo SET improves the sensitivity of detecting real alarms, thereby shortening the response time for patients.
(3) Improve the quality of care The accuracy of Masimo SET improves the quality of care and reduces the medical error rate.
