Oxygen inhalation instrument capable of monitoring oxyhemoglobin saturation and pulses

Abstract

An oxygen inhalation instrument capable of monitoring oxyhemoglobin saturation and pulses comprises a main control board, a liquid crystal screen, a power adapter or a battery, a blood oxygen and pulse module, a stepping motor, a regulating valve, a Venturi valve, a temperature sensor, an oxygen sensor, a pressure sensor and a heating module; the main control board comprises a CPU, a power supplymodule, a power interface, a liquid crystal screen serial port, a blood oxygen module serial port, a stepping motor interface, a temperature sensor interface, a heating module interface, an oxygen sensor interface and a pressure sensor interface. The oxygen inhalation instrument has the advantages that (1) the oxyhemoglobin saturation and the pulses of a human body are collected and displayed on the liquid crystal screen in real time; (2) the pressure of an oxygen source is detected; (3) the flow rate and the oxygen concentration are controlled by rotating the regulating valve; (4) the flow rate is automatically regulated, and the oxygen concentration is then regulated; (5) an oxygen inhalation pipeline is heated to control temperature; and (6) the heating speed is changed by changing voltage. Oxygen flow control and blood oxygen and pulse monitoring functions are achieved, and oxygen concentration regulation, oxygen concentration monitoring, oxygen source pressure monitoring and gas heating control are realized.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an oxygen inhalation instrument capable of monitoring blood oxygen saturation and pulse. Background technique [0002] First of all, the pace of life of modern people is accelerated, and the consumption of mental and physical energy is increasing. Especially for mental workers, because the brain is in a state of high tension for a long time, it is easy to cause brain hypoxia, cells lack endogenous oxygen, dizziness, chest tightness, fatigue, lethargy, Symptoms such as unresponsiveness and lack of concentration will affect normal study, work and life in severe cases; secondly, due to the increasing air pollution, the environment has insufficient oxygen, especially in winter, when many respiratory diseases are high-incidence period, such as asthma, chronic Lung obstruction and other causes the human body to be hypoxic; third, China has entered an aging society, and the prob...

AI Technical Summary

Problems solved by technology

Although the operation of ordinary oxygen inhalers is relatively simple and its price is not expensive, it only has flow adjustment and humidification functions, and there is no detection of parameters such as blood oxygen, pulse, and oxygen concentration.
