Device and method for measuring metabolic heat parameters

Abstract

The invention discloses equipment and a method for measuring metabolic heat parameters. The equipment comprises an earhole humidity / temperature probe, an oral cavity temperature probe, a body surface skin or oxter temperature probe, an environment temperature / humidity probe, a multi-way switch, a signal amplifier, an analog / digital (A / D) converter, a main controller, a storage unit, an input keypress, a display unit and a power supply, wherein the multi-way switch is connected with the probes and the signal amplifier respectively; the A / D converter is connected with the signal amplifier and the main controller respectively; and the main controller is connected with the storage unit, the input keypress and the display unit respectively, and is used for analyzing and processing detection data to obtain a blood sugar value. The equipment for measuring the metabolic heat parameters selects a corresponding empirical formula to calculate the blood sugar value according to the current physiological and pathological state of an examined person by simultaneously measuring core body temperature parameters and percutaneous thermal effect parameters of the examined person, and simultaneously measuring and recording various environmental parameters and physiological parameters, so that measured metabolic heat and blood sugar values are more accurate and reliable.

Description

technical field [0001] The invention relates to a measuring device and method for biological heating parameters. Background technique [0002] At present, most of the detection methods for blood glucose at home and abroad are invasive, that is, the patient's blood needs to be drawn and then measured by glucose oxidase method. Venous whole blood, plasma or serum glucose detection is carried out in the hospital, and capillary whole blood glucose detection can be tested by the patient himself with a small blood glucose meter. In order to achieve ideal blood sugar control goals, multiple tests must be performed in a day, including at least three meals before, after and before going to bed. If nocturnal hypoglycemia is suspected, additional testing is required. Although this type of method has high accuracy, it also has inevitable shortcomings. The first is that repeated blood draws many times a day bring great pain to the patient, and the second is that no matter in the hospi...

Problems solved by technology

The problems that must be solved by this kind of method are: the error caused by the difference of individual patients, the difference of the detection part and the difference of the skin state; the accuracy and reliability of the measurement; the influence of the change of other components in the blood; the processing of the detection data, etc.

[0005] But, inventor finds that prior art has following problem when realizing the present invention: this type of method does not consider various factors that influence the measurement accuracy of body surface temperature, as ambient temperature, humidity, wind speed, clothing, the contact condition of sensor and skin , the influence of skin thickness and even skin tone

It also does not consider the impact of the current physical or pathological conditions of the human body (whether exercising, difference in basal metabolic rate, whether there is fever, hyperthyroidism, liver disease, etc.)
