Abstract
A human body energy metabolism detector is an instrument for measuring carbon dioxide breathed out by a human body and used for checking the human body energy metabolism situation medically and clinically. The human body energy metabolism detector adopts a single chip microcomputer technology, and total mass of the carbon dioxide breathed out by the human body is calculated by measuring signals of a gas flow sensor and a carbon dioxide concentration sensor. The interference of the carbon dioxide in the environment is eliminated, and the total amount of the carbon dioxide produced by actual metabolism is measured. According to actually-input body parameters of a tested person, the referenced corresponding carbon dioxide discharge amount is calculated by using the internationally accreditated basal metabolic rate. The actual carbon dioxide discharge amount and the referenced carbon dioxide discharge amount are compared to obtain the body metabolism situation of the tested person.
Description
Technical field
The present invention relates to a kind of for measuring a kind of instrument of the carbon dioxide quality excreting in human body certain hour.Thereby the metabolism situation that indirectly reflects human body, is applied to the various clinical diseases of auxiliary diagnosis, as hyperthyroidism, diabetes etc.
Background technology
Carbon dioxide is one of primary product of body metabolism, and it is a kind of material that human body utilizes nutrient substance to produce through biochemical reaction in human body.The ability of the discharge capacity direct reaction human body substance metabolism of human body carbon dioxide.Equally, the Developmental and Metabolic Disorder of human body is also often accompanied by the generation of disease.As just very high in the basal metabolic rate of Patients with Hyperthyroidism, basal metabolic rate that can only manual measurement patient according to traditional method, process complicated difficult with hold and also result undesirable.The abnormal carbohydrate metabolism of patient of diabetes, causes human body cannot normally utilize nutrient substance to carry out the supply of body energy; Repeatedly there is abrasive survey blood glucose also to patient, to increase misery.
Summary of the invention
A kind of instrument of measuring human energy metabolism.By measuring the amount judgement body metabolism situation of the carbon dioxide of characteristics of contaminated respiratory droplets.
structure mainly comprises (Fig. 1)
Air inlet: air inlet is provided with two breather cheek valves, wherein check valve 1 is to make air can enter in air inlet; Valve 2 is that gas is entered in detector by air inlet is unidirectional.The effect of air inlet is to make gas unidirectional enter in detector, prevents reverse flow.
Detection of gas flow rate sensor: it is converted into voltage analog signal by the signal of gas flow rate and sends single-chip microcomputer to.And then calculate in certain hour by the volume of the gas of flow transducer.
Gas concentration lwevel sensor: its function is the concentration detecting by the carbon dioxide of gas.Gas concentration lwevel signal is converted into the analogue signal of voltage, this signal also sends the input end of analog signal of single-chip microcomputer to.
Air pump: the effect of air pump is that the power of gas flow is provided for detector.Air pump provides power in the detector pre-preparation stage for gas flow.Its structure as
fig. 2, the inlet end of air pump has check valve, but also can pass through air pump by pressure reduction in air pump off working state downstream.
Operation principle as
fig. 3.
Accompanying drawing explanation: Fig. 1 is the primary structure figure of human energy metabolism detector,
Fig. 2 is the structure chart of air pump,
Fig. 3 is the workflow diagram of human energy metabolism detector.
Claims (4)
1. measure the amount of certain hour body discharges carbon dioxide, there is a kind of instrument that human energy metabolism situation is assessed.
2. this instrument mainly contains gas flow sensor and gas concentration lwevel sensor detection signal, and carries out intelligence computation by single-chip microcomputer.
3. there is parameter input feature vector, the metabolic characteristics of subject person is compared with the basal metabolism calculating method of international endorsement, carry out metabolic evaluation.
4. measure and not disturbed by the carbon dioxide containing in environment.
