Problems solved by technology

[0002] Most of the traditional blood sugar detection or monitoring technologies use the so-called "invasive" measurement methods, which require frequent blood draws or finger pricks to take blood, and then analyze the blood, which brings great harm to patients. Painful and inconvenient, with increased chance of infection
In addition, the traditional "invasive" measurement method also has the following disadvantages: (1) It is not convenient for multiple continuous measurements, which brings difficulties to the continuous monitoring of blood glucose
(2) Consumables such as blood glucose test strips are needed during the measurement process, which increases the cost of use, which brings a lot of inconvenience and economic burden to the majority of patients

Embodiment 1

[0018] Example 1: A palm-type non-invasive blood glucose detection device using serial dual infrared spectroscopy detection and analysis that works in the near-infrared band (800nm-1100nm), such as figure 2 Shown.

[0019] The infrared light source 1 adopts a halogen lamp light source with a reflector. The light source has a continuous spectral distribution in the 800nm-1100nm spectrum; the light beam emitted by the light source illuminates one of the palms of the tested human body after passing through the reflector. The surface, then penetrates the palm of the hand and enters the double filter switch 4 in the cassette through the measuring hole; the light beam emitted by the double filter switch 4 enters the infrared sensor 5 and generates a voltage signal V, which is collected by the signal It is received by the processing circuit 6, and then transferred to the computer via the USB interface for analysis and calculation, and finally the blood glucose concentration information ...

Embodiment 2

[0023] Example 2: Fingertip type non-invasive blood glucose detection device using serial dual infrared spectroscopy detection and analysis that works in the short-wave infrared band (1000nm-1800nm), such as image 3 Shown.

[0024] The infrared light source 1 adopts a thermal emission light source with a collimating lens, which has a continuous spectral distribution in the 1000nm-1800nm ​​spectrum; the light beam emitted by the light source illuminates the finger of the measured human body after passing through the collimating lens The surface of the tip, then penetrates the fingertip into the measuring hole 3, and then enters the double filter switch 4; the light beam emitted by the double filter switch 4 enters the infrared sensor 5 in the hood and generates a voltage signal V , The voltage signal is received by the signal acquisition and processing circuit 6, and analyzed and calculated by the circuit, and finally the blood glucose information is displayed on the display.

Abstract

The invention discloses a noninvasive blood sugar measuring device adopting serial dual-infrared spectrum detection and analysis, belongs to the fields of optical measurement and novel medical detection devices, and especially relates to noninvasive human body blood sugar detection. The device is mainly composed of a broadband infrared light source, a double-optical filter switcher, an infrared photoelectric sensor, a signal acquiring and processing circuit and the like. The device adopts a transmission spectrum measurement way; a light beam emitted by the broadband infrared light source is irradiated on relevant parts of a human body to be tested, such as fingertips and palms, penetrates through human body tissues, reacts with blood, and then enters the double-optical filter switcher; andthe double-optical filter switcher adopts a serial working mode, and allows light beams with two different wavelengths to go through an optical filter and then received by the unit infrared photoelectric sensor. The signal acquiring and processing circuit converts the electrical signal of the infrared photoelectric sensor into a digital signal, and analyzes and calculates the signals of the two different wavelengths to finally obtain human body blood sugar concentration information.
