Abstract

The invention discloses an electronic vital capacity tester for measuring a vital capacity of a human body. The electronic vital capacity tester comprising a housing assembly, a blowing assembly, a differential pressure sensor and an electronic control device; wherein the blowing assembly comprises a blowing pipe including a throttle device with an orifice. The electronic control device includes avital capacity main control board, which includes a main control circuit, a storage module, and a flow measurement circuit. The storage module includes a differential pressure-flow function program module and a vital capacity calculation module, wherein the differential pressure-flow function is a differential pressure-flow segmented fitting function. The vital capacity calculation module can calculate the total vital capacity value by means of the integral calculation by means of the differential pressure-flow function program module. The invention also discloses an IoT-based vital capacitytest system. The invention has the beneficial effects that the measurement accuracy of the vital capacity is greatly improved, and a user can conveniently measure the vital capacity anytime and anywhere.

Description

technical field [0001] The present invention relates to the technical field of measuring the volume of inhaled or exhaled air, such as vital capacity (A61B 5 / 091), and in particular to electronic spirometers. The present invention also relates to a spirometry testing system based on the Internet of Things. Background technique [0002] Vital capacity refers to the amount of gas exhaled by the human body after one maximum inhalation, which is used to represent the maximum functional ventilation of the lungs at one time, and is one of the main indicators reflecting the level of human growth and development. A spirometer, or spirometer, generally refers to an instrument used to measure lung capacity. According to different test principles, there are mainly two types of volumetric spirometers and flow velocity spirometers. [0003] The differential pressure spirometer calculates the flow rate by detecting the pressure change of the gas flowing through the throttle valve. When...
