Method and device for monitoring controlling oxygen inhalation instrument

Abstract

The present invention discloses a method and an installation of monitoring and controlling an oxygen inhalator. Under the control of a microcomputer, an upper limit and a lower limit of a patient blood oxygen saturation are set, and a preset flow velocity ratio is set for the oxygen inhalator. The oxygen inhalator is opened and supplied with oxygen at the preset flow velocity, after a period of time, the blood oxygen saturation inside the body of the patient who inhales oxygen is inspected, the flow velocity of a proportion electromagnetic valve which is in series in an gas path of the oxygen inhalator is regulated properly until the blood oxygen saturation is within a preset range. The apparatus not only has the characteristics of the oxygen inhalator and a monitor but also closely combines the oxygen inhalator and the monitor to realize an interaction. The apparatus provides monitoring of life sign parameters such as the blood oxygen saturation and can automatically change an oxygen inhalation flow velocity with the preset flow velocity range according to the timely collected changes of the patient life singe such as the blood oxygen saturation and accordingly a patient oxygen inhalation concentration is changed, then the patient life sign is improved.

Description

technical field [0001] The invention relates to a medical method and equipment, in particular to a control method and device for an oxygen inhalation instrument. Background technique [0002] Oxygen inhalers (oxygen inhalation devices) are relatively common on the market at present. It is a medical device that changes the oxygen flow rate by manually adjusting a throttle valve to achieve oxygen therapy or health care for patients. Its disadvantages are: [0003] 1. The function is single, it can only provide oxygen inhalation function for the patient; it cannot provide oxygen therapy monitoring at the same time, so it may lead to the occurrence of adverse reactions of oxygen therapy such as oxygen poisoning; [0004] 2. The patient's physiological signs such as pulse oxygen saturation, pulse rate, blood pressure, etc. need to be monitored by additional special equipment; [0005] 3. As the patient's condition changes, doctors often need to reset the oxygen flow rate repea...

AI Technical Summary

Problems solved by technology

[0003] 1. The function is single, it can only provide oxygen inhalation function for the patient; it cannot provide oxygen therapy monitoring at the same time, so it may lead to the occurrence of adverse reactions of oxygen therapy such as oxygen poisoning;

[0004] 2. The patient's physiological signs such as pulse oxygen saturation, pulse rate, blood pressure, etc. need to be monitored by additional special equipment;

[0005] 3. As the patient's condition changes, doctors often need to reset the oxygen flow rate repeatedly;

[0006] 4. And because it cannot be "adjusted in time as needed", it will waste oxygen;

[0007] 5. Due to the lack of necessary alarm measures, uninterrupted care by doctors or nurses is often required in hospitals;

[0008] 6. When using this oxygen inhalation instrument at home, patients often do not have vital signs monitoring equipment, and at night

[0009] If there is no timely care, because there is no necessary alarm measures to remind, it may bring very serious consequences to the patient
