Respiratory support equipment and control method thereof

Abstract

The invention provides a control method of an oxygen therapy instrument. A pressure sensor is added in an air outlet of the oxygen therapy instrument to detect the respiratory conditions of a user, during inspiration of the user, oxygen is output by controlling a proportional valve, and during expiration of the user, oxygen output is closed. The control method of the oxygen therapy instrument hasthe advantages that under the situation that the user needs the same oxygen flow, the oxygen therapy instrument of the method reduces the power of oxygen production by 2/3, and then the noise of oxygen production and the size of the oxygen therapy instrument can also be correspondingly reduced; continuous oxygen delivery can cause dry injury of the mucous membrane in the local respiratory tract, and during expiration, oxygen output is stopped so that the breath of the patient can be more smooth; the breath state can be accurately judged, the control precision of the oxygen flow is high, the adjustment of the oxygen output amount is sensitive, the comfort of the oxygen inhalation is improved, and side effects are reduced; a blood oxygen detection module is added to detect the oxyhemoglobinsaturation of the user during use and monitor the treatment condition of the user in real time, and the oxygen flow is intelligently adjusted according to the oxyhemoglobin saturation to save energy under the best treatment effect.

Description

technical field [0001] The present invention relates to the technical field of respiratory support equipment, in particular to a respiratory support equipment and a control method thereof. Background technique [0002] Existing general oxygen therapy equipment consists of filter, oil-free air compressor, molecular sieve tower, cooling system, on-off valve, proportional valve, muffler and gas storage tank, etc. The adjustment of oxygen is controlled by adjusting the proportional valve to adjust the oxygen flow rate. The flow rate of oxygen inhaled by the user, during the user's use, according to the flow rate set by the user, the oxygen supply will continue during the user's inhalation process and during the exhalation process, and the oxygen output cannot be adjusted according to the user's own breathing conditions. Adjustment, during the breathing process of the user, the oxygen therapy device continuously outputs oxygen. When the user exhales, the oxygen is discharged into...

AI Technical Summary

Problems solved by technology

However, this kind of oxygen infusion device has problems such as misjudgment of breathing status, low accuracy of oxygen flow control, insensitive adjustment of oxygen output, etc., which cannot achieve the best therapeutic effect, and the noise of oxygen production is large, which wastes oxygen production power.
