Problems solved by technology

These two methods have limited oxygen supply, it is inconvenient to require frequent dosing or bottle replacement, and there is also the problem of high price.
In addition, when supplying oxygen to people, regardless of whether the patient is inhaling or exhaling, oxygen will be released continuously as soon as the valve is opened. As a result, half of the oxygen will be wasted when the patient exhales, consuming energy and money. And frequent feeding or changing bottles is not only troublesome, it may also delay rescue treatment sometimes

Embodiment Construction

[0008] As shown in Figure 1, the electronic control device for household oxygen breathing includes: a breathing rhythm sensor a, a control circuit b, an air circuit switch c, a modified stereo earphone d and a digital FM radio e. Among them, d is to choose a stereo earphone with a microphone bracket sold on the market. The way to modify it is to remove the microphone, and use the bracket and connecting line to install the breathing rhythm sensor and the air outlet of the oxygen tube. When putting on the earphone, make the air outlet of the breathing rhythm sensor and the oxygen tube just in front of the nostril, that is, the position of the original microphone. The breathing rhythm signal detected by the sensor is amplified by the control circuit to control the opening and closing of the air circuit switch, so that the oxygen channel is opened when the person inhales, and the oxygen channel is closed when the person exhales.

Abstract

The present invention relates to an oxygen inhalation control device. Said device includes respiratory rhythm sensor, control circuit, gas circuit switch, modified stereoearphone and digital FM radio. Said stereoearphone can be used as supporting frame for placing the respiratory rhythm sensor and oxygen gas nozzle in the front of nose of the person inhaling oxygen gas, so that at the same time of inhaling oxygen gas the patient also can listen to radio. According to respiratory rhythm of human body said invention can control the make-breake of the oxygen supply gas circuit so as to attain the effect of saving gas and prolonging service time.

Description

technical field [0001] The invention relates to an electronic control device for household oxygen inhalation, in particular to an electronic control device that can control the on or off of the oxygen supply circuit according to the human breathing rhythm (inhale on, exhale off) when people inhale oxygen. ) control device for saving oxygen. Background technique [0002] Medical rescue or health care oxygen inhalation has been gradually extended to families. At present, in the field of household oxygen supply equipment, chemical oxygen production - "oxygen Lide" and container oxygen supply - "oxygen bottle" or "oxygen bag" are the most used. These two methods all have the problem of limited oxygen supply, requiring frequent dosing or changing bottles to inflate, which is very inconvenient, and also has the problem of high price. In addition, when supplying oxygen to people, regardless of whether the patient is inhaling or exhaling, oxygen w...
