Embodiment Construction

[0013] Such as figure 1 The multi-element photoelectric sensor shown includes a light guide 1, an upper shell 2 and a tube socket 4. The upper end surface of the tube socket 4 is fixedly connected with four photoelectric chips 3, and the upper shell 2 is fixedly connected to the tube socket 4 On the upper end surface, the light guide body 1 is fixedly connected to the upper shell 2, and the bottom of the tube socket 4 is connected with a pin 5, and the pin 5 is separately led from the anodes of the four photoelectric chips 3 and the four photoelectric chips The cathode of 3 is connected to one body, and the upper shell 2 is drawn out through the tube socket 4. The upper shell 2 is provided with a groove for the light guide 1 to be embedded, and the four photoelectric chips 3 are in the shape of "well" The four photoelectric chips 3 have receiving wavelengths of 416nm, 660nm, 940nm and 1025nm, respectively, and the light guide bandpass width of the light guide body 1 is 250nm-25...

Abstract

The invention discloses a multi-element photoelectric sensor. The multi-element photoelectric sensor comprises a light guide body, an upper shell and a tube base. The upper end face of the tube base is fixedly connected with four photoelectric chips. The upper shell is fixedly connected to the upper end face of the tube base. The light guide body is fixedly connected to the upper shell. The bottom of the tube base is connected with pins. The pins are formed in the manner that anode electrodes of the four photoelectric chips are independently led out, cathode electrodes of the four photoelectric chips are led out after being connected into a whole and the upper shell is led out through the tube base. By adopting the multi-element photoelectric sensor, noninvasive blood glucose detection on patients is achieved, the pain of the patients is reduced, and wound infection is avoided.

Description

technical field [0001] The invention relates to a multi-element photoelectric sensor and belongs to the technical field of blood sugar detection devices. Background technique [0002] With the significant decline in the labor intensity of modern humans and changes in eating habits, as well as the aggravation of population aging, the incidence of diabetes has risen rapidly. The impact of diabetes and its complications has become a serious public health problem that all countries in the world must face one of the problems. More and more diabetic patients need to monitor blood sugar in the body several times a day or at any time according to their physical conditions. Generally, patients need to test blood sugar 5-6 times a day, but most of the blood glucose meters on the market are invasive. Acupuncture is required to take blood, which will cause about 2,000 acupuncture injuries a year. Such many wounds not only bring great inconvenience and pain to patients, but also may cau...
