Problems solved by technology
Oxygen infusion is effective for those who suffer from oxygen absorption disorder or insufficient ventilation due to lung tissue lesions affecting ventilation function; for those with oxygen transport disorders caused by circulatory insufficiency or anemia, oxygen infusion has a certain effect, but it cannot fundamentally solve hypoxia question
[0003] However, the existing oxygen supply device, its output oxygen partial pressure is not stable enough, this problem needs to be solved urgently

The invention discloses an oxygen supply device with high stability during output of oxygen partial pressure. The oxygen supply device comprises a floating ball, a connector and a bottle body. A pressure-stabilizing built-in bottle is arranged in the bottle body, the portion between the bottle body and the pressure-stabilizing built-in bottle is filled with diatomite, nitrogen is stored in the pressure-stabilizing built-in bottle, an electromagnetic valve controlled by a single-chip microcomputer is arranged on the pressure-stabilizing built-in bottle, an oxygen partial pressure detection device is further arranged in the bottle body, and the oxygen partial pressure detection device is electrically connected with the single-chip microcomputer. According to the oxygen supply device, the output oxygen partial pressure is very stable, when fluctuation of the oxygen partial pressure exists in the bottle body for various reasons, the pressure-stabilizing built-in bottle in the bottle body can return the overcharge and demand payment of the shortage of oxygen, and therefore stable output of the oxygen partial pressure is kept.
Description
technical field [0001] The invention relates to an oxygen supply device, in particular to an oxygen supply device with high stability of output oxygen partial pressure. Background technique [0002] At present, oxygen supply devices are widely used in hospitals. The bead type glass rotor oxygen flowmeter is an essential instrument for rescue and treatment of patients in hospitals. The accuracy of its measurement performance directly affects the treatment effect of patients. The main function of oxygen therapy is to increase the arterial partial pressure of oxygen, improve the oxygen supply of the human body, and reduce the increased respiratory and circulatory burden due to compensatory hypoxia. The causes of hypoxia caused by different diseases are different, and the effects of oxygen delivery are also different. Oxygen infusion is effective for those who suffer from oxygen absorption disorder or insufficient ventilation due to lung tissue lesions affecting ventilation f...
