The application relates to the technical field of oxygen flow control of an oxygen generator, and discloses an oxygen generator flow automatic control method and system, an oxygen generator flow automatic control method, which comprises the following steps: configuring a target oxygen configuration flow and a target oxygen concentration required by target personnel; acquiring actual oxygen flow and actual oxygen concentration in real time; calculating an effective oxygen uptake deviation; when the effective oxygen uptake deviation is not lower than a specified oxygen uptake, dynamically acquiring a short-time oxygen configuration flow; generating a flow control signal through a preset PID control algorithm based on the deviation between the short-time oxygen configuration flow and the actual oxygen flow; and driving a flow adjustment actuator to output oxygen according to the flow control signal; a first parameter group is adopted during an inhalation phase of the target personnel, and a second parameter group is adopted during an exhalation phase of the target personnel, wherein, and, the response delay of the patient during a rapid inhalation phase is reduced, the oxygen waste during the exhalation phase is reduced, and the method is especially suitable for irregular breathing modes of COPD patients.

The utility model relates to medical instrument technical field discloses oxygen inhalation timer, including humidification bottle, humidification bottle, connecting pipe body and flowmeter, one side of connecting pipe body is provided with oxygen outlet pipe, the one end away from connecting pipe body of oxygen outlet pipe is provided with control pipe seat, the surface center of control pipe seat upper end is provided with timer body, the switch button of timer body is close to oxygen outlet pipe one side lower extreme and is provided with, both ends of control pipe seat all are seted up to have the mounting hole, control pipe seat is close to oxygen outlet pipe one end and is provided with valve structure through mounting hole. The oxygen inhalation timer, when the patient needs oxygen inhalation, the patient can dial the dialing rod, drives the cam to rotate, the front end of the cam will contact and extrude the switch button in the cam rotating process, realize the switch button to open the timing, at the same time, the ball body is driven to rotate synchronously through the rotating shaft when the cam rotates, the through -hole on the ball body is opened, the patient can inhale oxygen, realize the patient to inhale oxygen and start timing simultaneously, guarantee timing accurate.

This invention discloses a method and device for coordinated regulation of rest-based oxygen supply based on fatigue grading, relating to the field of oxygen supply regulation technology. The method includes: S1, collecting fatigue-oxygen coordination data and performing preprocessing on the data; S2, dividing the respiratory phase window, generating an oxygen generation gating code sequence and an air supply gating code sequence, and generating a gated fatigue response kernel group through sliding inner product decoding and Wiener deconvolution processing; S3, calculating the blood oxygen uptake phase drift value, the heart rate bradycardia slope loss value, and the respiratory rhythm broadening value, and generating a fatigue grading result based on the periodic variation relationship of these three values; S4, constructing a grade constraint response matrix, solving for the execution adjustment vector, performing avoidance correction on the execution adjustment vector, and outputting the coordinated regulation result of rest-based oxygen supply. This solves the problem that existing rest-based oxygen supply equipment is difficult to combine fatigue grading and respiratory phase coordinated regulation to control oxygen supply and air delivery, resulting in delayed oxygen supply to the mouth and nose area and a lack of stable quantitative evidence for blood oxygen recovery.
