Lag-free oxygen supply breathing machine system

Abstract

The invention discloses a lag-free oxygen supply breathing machine system, which comprises a breathing mask, an inspiration pipe, an expiration pipe, an oxygen supply chamber, an auxiliary oxygen supply pipeline and a start-stop cylinder used for opening and closing the auxiliary oxygen supply pipeline, and the breathing mask is communicated with the oxygen supply chamber through the inspiration pipe and the auxiliary oxygen supply pipeline. the breathing mask is communicated to outside, the auxiliary oxygen supply pipeline is arranged, a small amount of oxygen is supplied at the later half stage of expiration, and the oxygen amount needed by a user within the time when the respirator induces the inspiration airflow lagging time is made up; the situation that a user needs to supply oxygen for inspiration lags, and inspiration is difficult is avoided, better breathing experience is provided for the user, starting and stopping of the auxiliary oxygen supply pipeline are controlled through airflow of the expiration pipe, control is easy and convenient, expiration is smoother, the temperature of oxygen provided by the auxiliary oxygen supply pipeline is adjustable, and breathing is more comfortable.

Description

technical field [0001] The invention relates to the technical field of ventilators, in particular to a hysteresis-free oxygen supply ventilator system. Background technique [0002] Ventilator is a device that can replace, control or change people's normal physiological breathing, increase lung ventilation, improve respiratory function, reduce breathing work consumption, and save heart reserve capacity. [0003] When assisted breathing is triggered by airflow, it can keep the ventilator working in sync with the patient's inhalation, so as to facilitate the evacuation of the ventilator. However, due to the limitation of the airflow detection synchronization device, when the patient starts to inhale, the ventilator can be synchronized about 20ms later. This creates a lag in breathing and oxygen supply. The faster the patient's breathing rate, the longer the lag time of the ventilator, the more the patient's work of breathing, and the poorer the breathing experience. Contents...
