Embodiment Construction

[0022] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0023] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0024] Many experiments have proved that organisms can not only conduct electricity, but also generate bioelectricity in the process of metabolism. This bioelectricity can be projected to the surface of the skin in a conductive form through the electrolyte of the tissue, forming the phenomenon of skin electricity. Acupuncture points (blocks) are contacts of bioelectric current and have different electrical properties from ...

Abstract

The invention discloses a noninvasive blood glucose measurer. The noninvasive blood glucose measurer comprises a housing and a work circuit board. A probe assembly is mounted in the housing, the probe assembly has two electrodes used for contacting with different skin portions of the human body, so as to measure potential difference between the two different skin portions. The work circuit board is mounted in the housing. The work circuit board comprises a potential difference unit, a processing unit and a power unit. The potential difference unit is electrically connected with the probe assembly and used for calculating the potential difference. The potential difference calculated by the potential difference unit is input to the processing unit. The power unit is used for supplying power to the work circuit board. The processing unit records a linear proportion relation formula between the blood glucose level and the potential difference, so the processing unit can calculate the blood glucose level according to the potential difference. By adopting the noninvasive blood glucose measurer, needle prick is needless, only the potential difference between two skin areas of the human body needs measuring, measured patient' pain caused by needle prick can be removed.

Description

technical field [0001] The invention relates to a blood glucose detector, in particular to a non-invasive blood glucose detector. Background technique [0002] Blood sugar is one of the more important indicators of diabetes. Diabetics must control their blood sugar levels throughout their lives and use real-time blood sugar levels as the basis for taking or administering insulin. Around 1840, rough urine sugar or cumbersome venous serum was used as the basis for blood sugar measurement. Initial urine sugar was tested by Benedict's solution burning method, which was later replaced by oxidase test paper method. Since urine sugar appears when the blood sugar level exceeds 180mg / dL (10mmol / dL), and dietary diabetes can seriously cause misjudgment, it is still widely used only in some poorer or poor medical resource areas. And venous serum is even more inconvenient and impossible to popularize to diabetic patients to test blood sugar in time at any time. So at that time, scien...
