Embodiment 1

[0136] Embodiment 1 Referring to Fig. 1, Fig. 1 is a schematic diagram of the structure of a desktop non-invasive blood glucose detector. The detection site is the ear hole, and the temperature detection head is preheated by one ear, and the formal detection is performed by the other ear hole. It includes a shell 1, a movement inside the shell and a probe connected to the shell, and is characterized in that:

[0137] There are operation buttons 7 and input keys 8 for invasive detection of blood sugar level for calibration on the surface of the shell; there are two input keys for invasive detection of blood sugar level for calibration, marked with up and down arrows respectively. By pressing the button, the invasive blood glucose value can be input into the instrument for calibration.

[0138] The movement consists of the following components connected in sequence:

[0139] (a), the preamplifier used to amplify the weak temperature electrical signal input by the probe head. T...

Embodiment 2

[0158] Embodiment 2, see Fig. 3, Fig. 3 shows another design of non-invasive blood glucose detector. It differs from the design shown in Figure 1 only in that a battery 8 is used instead of the AC power source. The corresponding switching power supply circuit 6 also needs some changes to adapt to the feature that the battery voltage keeps dropping during use. Ready-made voltage regulator integrated circuits can be purchased for assembly, and such products are available in the market.

Embodiment 3

[0159] Embodiment 3, refer to FIG. 4, which shows another non-invasive blood glucose detector of another design. It differs from the previous two in that the temperature probe is not heated by an ear to achieve the desired initial temperature, but controlled by a heating-cooling unit built into the instrument. 14 among the figure is heating-cooling unit, and it is controlled by single-board computer system 4, is powered by regulated power supply 6, and utilizes semi-conductor energization to generate heat or cool down. Such semiconductors can be purchased assembled.

[0160] The fourth non-invasive blood glucose detector design is different from the previous three in that the temperature probe is changed into a patch form, which is attached to the skin of a certain part of the body (such as the armpit), so that the instrument is uninterrupted 24 hours a day Monitor the temperature changes of the patches. Instead of checking body temperature every once in a while, it monitors...

Abstract

The invention discloses a non-invasive blood sugar detecting instrument which comprises a casing, a movement in the inner portion of the casing and a detecting head which is connected with the casing. The surface of the casing is provided with an operational push-button and an input key which marks the invasive blood sugar value, and the movement comprises a preamplifier, an A/D conversion circuit, a MCU system, a display, an acoustic prompting and warning circuit, a switch voltage stabilized source circuit, a power supply switch and an alternating current power supply socket. The detecting head is constituted by the connection of the temperature measuring contact of a temperature sensor on the front end and an ear notch accommodator on the rear portion, wherein the ear notch accommodator is constituted by a thermosensitive resistor temperature sensor on the middle portion, coated good heat conductor filling and metal shell, and the thermosensitive resistor temperature sensor is connected with a conversion circuit which transforms temperature signal into electrical signal and the preamplifier in the movement through wires. The invention solves the problems of non invasive, low cost and the precision detecting of blood sugar value.

Description

(1) Technical field [0001] The invention relates to a blood glucose detector. (2) Background technology [0002] Diabetes mellitus is a group of metabolic abnormal syndromes caused by the interaction of genetic and environmental factors. Due to defects in insulin secretion, insulin action, or both, the metabolism of carbohydrates, proteins, fats, water, and electrolytes is caused. Disorder, clinically with chronic (long-term) hyperglycemia as the main common feature. At present, there are about 132 million diabetic patients in the world, and it is expected to reach 240 million by 2010, and about 3 / 4 of new diabetic patients are in developing countries. Currently, there are 20 million to 30 million patients in my country, and 30 million to 40 million patients with impaired glucose tolerance. These data will also increase at a rate of nearly 10 million per year. [0003] The etiology and pathogenesis of diabetes are not yet fully understood, and there is a lack of effective...
