Description
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to portable annular oxyhemoglobin saturation measuring apparatu.
Background
During the transmission of blood in the vascular system, the waveform of the volume change and the concussion phenomenon generated by the heart beat becomes the pulse wave, which is the theoretical basis of the blood oxygen data analysis. By acquiring an accurate pulse wave from the human body, the blood oxygen saturation in the blood of the human body can be calculated.
At present, the following two methods are mainly used for measuring the blood oxygen saturation: electrochemical methods and photochemical methods, wherein photochemical methods further include light absorption measurements and light reflectance measurements. The electrochemical method requires invasive blood collection, and generally involves arterial blood detection as a main step, followed by electrochemical analysis to obtain arterial oxygen partial pressure, and calculating arterial oxygen saturation according to the obtained result. Although this method can obtain relatively accurate and reliable data, it cannot perform continuous measurement and causes pain to the tester, and it is rarely used at present. The most obvious advantage of photochemical method over electrochemical method is non-invasive detection, and the principle basis for measuring blood oxygen saturation by photochemical method is the Beer-lambert law (Beer-lambert law), which is widely used in optical experiments.
lambert-Beer law (Beer-lambert law) states that: at a certain wavelength, the proportion of light absorbed by the transparent medium is independent of the intensity of the incident light and is dependent on the concentration of the light-absorbing substance and the thickness of the absorbing layer; it describes the attenuation characteristics of light after passing through a non-scattering medium of uniform absorption properties. The pulse wave definition can know that the volume changes due to the tunny and the heart pulsation in the blood transmission process of the vascular system, so that the optical path changes, the optical path changes cause the change of the light absorption amount of the arterial blood, the signal intensity output by the blood oxygen probe changes along with the change of the pulse wave, and the blood oxygen saturation can be obtained by processing the signal.
The existing pulse oximeter is mainly in a finger-clamping type, a user needs to clamp the pulse oximeter on a finger head and then starts equipment to measure, and inconvenience is caused in the long-time measurement process; in the clamping process of fingers with different thicknesses, a stable signal position is not easy to find, not all finger shapes and thickness sizes can find a perfect signal acquisition point, and the device may face larger noise interference in the measurement process; the fixed position of finger clip formula oximetry is close to the finger end, easily drops during the measurement, leads to the measuring result inaccurate, awaits further improvement urgently. Secondly, most of the existing blood oxygen measuring devices are offline measuring, and only the current measuring result is displayed or only the measuring results of limited times are recorded; and the data visualization display form is single, and the data visualization display is not rich and beautiful enough.
