Embodiment

[0030] figure 1 It is a schematic structural diagram of the signal acquisition device of this embodiment.

[0031] Such as figure 1 As shown, the signal acquisition device 100 includes an acquisition clip 10 , a sensor circuit unit 20 , a peripheral signal conditioning circuit 30 and an analog-to-digital converter 40 .

[0032] The collection clip 10 is used to hold the finger of the human body, which is similar to the clip used to hold the finger of the nail oximeter. There are a first clip 11, a second clip 12 and a torsion spring 13 assembling the two groups to cooperate with each other. Form the collection clip.

[0033] The sensor circuit unit 20 is arranged on the inside of the first clip or the second clip in the collection clip, and has an infrared light emitting module 21, a blood oxygen concentration value detection module 22, a human body thermal infrared radiation detection module 23, an ambient temperature detection module 24, Human body surface temperature det...

Abstract

The present invention also provides a signal acquisition device for collecting physiological parameters at the finger of the human body, which is characterized in that it includes: a collection clip for holding the finger of the human body; a sensor circuit unit arranged inside the collection clip and having an infrared light emitting module As well as the blood oxygen concentration detection module, human body thermal infrared radiation detection module, ambient temperature detection module, human body surface temperature detection module and heart rate detection module, the near-infrared light emitted by the infrared light emitting module passes through the human finger and is received by the corresponding module Afterwards, the blood oxygen concentration value, the human body thermal infrared radiation value, the ambient temperature value, the human body surface temperature value and the heart rate value are detected respectively; Analog values ​​are converted into digital quantities. Correspondingly, a method for obtaining the blood glucose concentration value by using the parameter signal detected by the device is also provided.

Description

technical field [0001] The invention belongs to the technical field of medical electronics, and in particular relates to a non-invasive blood sugar calculation method based on an energy conservation method and a corresponding signal acquisition device. Background technique [0002] The sugar in the serum is called blood sugar, and in most cases it is glucose. Most of the energy required for the activities of various tissue cells in the body comes from glucose, so blood sugar must be maintained at a certain level to maintain the needs of various organs and tissues in the body. Under normal circumstances, the human body can ensure the balance between the source and outlet of blood sugar through the two major regulatory systems of hormone regulation and nerve regulation, so that blood sugar can be maintained at a certain level. If a person's blood sugar level is not in the normal standard, it will cause great harm to people's health. Therefore, regular and effective detection...
