Title: Non-invasive oximeter, the detecting method thereof, and the method for detecting peak and valley of the wave signals
Inventor: LIN YU-MING
IPC: A61B5/02
Filed: 1998-12-30
Granted: 2001-01-11
Abstract: Pulse oximeter can measure the oxygen concentration in blood. The measurement is not by analyzing the blood sample but by a noninvasive optical modulation technique which contains two light beams of wave lengths at 660nm which is absorbed by oxyhemoglobin and 940nm which is absorbed by deoxygenated hemoglobin, respectively. We apply oximeter on high blood vessel-densitied areas such as the ear lobe and finger. The intensity of the penetrating light represents the concentration of oxyhemoglobin and deoxygenated hemoglobin. The changing signals of oxyhemoglobin and deoxyhemoglobin are obtained individually before obtaining the electrical signals of the two hemoglobins by the optical-electrical transformer. The blood-leveled oxygen then is calculated with a microprocessor according to the formulated definition of the blood- leveled oxygen. Correct values of the wave peak and valley can be found by signal tracking each point of the wave shape of the blood-leveled oxygen. The above oximeter and detection method prevent heavy pulse wave interference and overcomes the conditions of poor signals or baseline shift. The heart rate and blood-leveled oxygen from the signal thus can be further calculated. This method increases the accuracy and reliability of this product.
