Description
Technical field
The present invention relates to measure the device technique field of pulse, heart rate, blood pressure or blood flow, relate in particular to a kind of blood oxygen instrument and blood oxygen collection monitoring system thereof.
Background technology
The main measurement index of blood oxygen instrument is respectively pulse frequency, blood oxygen saturation and perfusion index (PI).Blood oxygen saturation (oxygen saturation is abbreviated as SO2) is one of basic data important in clinical treatment.Blood oxygen saturation refers to that in whole blood volumes combined O2 capacity accounts for the percentage ratio of whole combinative O2 capacity.
An initial blood oxygen degree of saturation instrument is developed in the forties in 20th century by Millikan, the ratio of carrying the hemoglobin of oxygen and not carrying the hemoglobin of oxygen for monitoring tremulous pulse.Typical blood oxygen saturation instrument is with two light emitting diodes, and these two light emitting diodes are towards detected part-normally finger tip or ear-lobe of patient.It is the light beam of 760 nanometers that a diode discharges wavelength, and another discharges the light beam of 850 nanometers.Absorbance and the oxygen-free difference of oxygen containing hemoglobin to these two kinds of wavelength is very large.Utilize this character, can calculate the ratio of two kinds of hemoglobin.The process of test need to not drawn blood from patient conventionally.Common blood oxygen instrument also can show patient's pulse.According to Beer-Lambert law, the functional relationship of ratio R/IR and arterial oxygen saturation (SaO2) should be linear relationship, but because biological tissue is a kind of strong scattering, weak absorption, anisotropic complicated optical system, not in full conformity with classical Beer-Lambert law, thereby caused expression HONGGUANG change measure relative to infrared light absorbance (R/IR value), and the Mathematical Models difficulty of relation between arterial oxygen saturation (SaO2).Can only method by experiment determine the corresponding relation of R/IR and SaO2, i.e. calibration curve.Most of pulse blood oxygen instrument manufacturer all obtains empirical calibration curve to complete the pre-calibration before product export with experimental technique.
The oximeter that prior art exists, all single individual's test blood oxygen, countless according to preservation, also can user's historical data not preserved and be analyzed, more individual health and fitness information can not fed back to hospital or children of the family, it is a simple survey tool, does not have data acquisition and monitoring system, does not embody scientific and technological developing direction.
