Lung gas detecting instrument

Abstract

The invention provides a lung gas detecting instrument which comprises a air pipe, a gas pressure sensor, an alcohol sensor, a control circuit and a LCD display screen, wherein, the gas pressure sensor and the alcohol sensor are communicated with the air pipe; the control circuit comprises a single chip microcomputer, a sampling circuit of the alcohol sensor, a power supply circuit of a power source, and a LCD driving circuit; the single chip microcomputer is connected with the voltage output end of the power supply circuit of a power source; the gas pressure sensor is respectively connected with the single chip machine and the voltage output end of the power supply circuit of the power source; the alcohol sensor is connected with the voltage output end of the power supply circuit of the power source; the sampling circuit of the alcohol sensor is respectively connected with the single chip machine and the alcohol sensor; and the LCD driving circuit comprises a display driving chip which is respectively connected with the single chip machine, the LCD display screen and the voltage output end of the power supply circuit of the power source. The detecting instrument has the advantages of stable property, complete function and accurate detecting data, can be used as a judging tool for administrative enforcement of law, and also can be used for physical examination of medical treatment organization and family health care.

Description

technical field [0001] The invention relates to a device for human health examination, in particular to a lung gas detector with functions of lung capacity test and alcohol content test. Background technique [0002] In recent years, the medical field has taken spirometry testing as an important item to detect human health. People with large lung capacity not only have good cardiovascular function, but also have relatively strong muscle activity and body oxygen supply capacity; Such spirometry testing equipment is mostly used in medical institutions for physical examination. In recent years, with the continuous improvement of people's health awareness, these equipment have gradually entered the family, that is, they are used for health examination and physical care of family members; [0003] At present, there are various breath alcohol content detectors on the market, which are used to detect the alcohol content in the breath of the human body, and are a rapid test device f...

Problems solved by technology

[0004] The above-mentioned equipment and instruments are all used for routine detection of lung gas, with a single function. Moreover, the error of the detection data is too large, which may easily make the reference value of the human health examination inaccurate, and easily cause the accuracy and standardization of administrative law enforcement to fail. standard; in order to solve the above problems and ensure a perfect and accurate detection of human lung gas, people have been seeking an ideal technical solution
