Description
Technical Field
The utility model relates to the technical field of blood analysis, in particular to noninvasive blood analysis equipment based on spectrum analysis.
Background
At present, most blood routine detectors used in hospitals adopt a laser scattering mode, a blood sample plate is irradiated by laser, after the laser passes through the sample, the laser beam is scattered, the scattering rule of the laser beam is related to the components in the blood, and then the scattered laser is analyzed and counted to calculate and deduce the components in the blood. However, such methods of use necessarily require that a sufficient sample of the patient's blood be drawn. The cost of detection is not increased, and vein blood collection is needed for blood collection, if a patient has infectious diseases or bacteria exist in a blood collection environment, the risk of infection is not increased; of course, the conventional blood routine detector includes a photoelectric type, a capacitive type, a resistive type, and the like, in addition to the laser scattering type described above. But they all require that enough blood be collected from the patient to be analyzed.
As for blood glucose levels, it is not the case in conventional medical projects. The glucose oxidase is usually adopted to react with glucose in a blood sample, then a weak current is generated on an electrode of the blood glucose test paper, and after amplification and integral operation of an amplifier in the blood glucose meter, the content of glucose in blood can be estimated, namely the blood glucose value. Because the magnitude of the current generated by the reaction of glucose oxidase is proportional to the magnitude of the glucose concentration in blood, given a sufficient amount of glucose oxidase. Moreover, this reaction requires a trace amount of blood collection from the tip of the fingertip. However, even in the case of micro-blood collection, since invasive operations are required for the patient, any analysis of blood-related components has been conventionally performed only by performing invasive blood collection on the patient. Different methods and different detection items only differ in the amount of blood collected. To this end, we propose a non-invasive blood analysis device based on spectroscopic analysis.
