Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0027] refer to figure 1 , a non-lag oxygen supply ventilator system, including a breathing mask 1, an inhalation tube 2, an exhalation tube 3, an oxygen supply chamber 4, an auxiliary oxygen supply pipeline 23 and a start-stop cylinder 5 for opening and closing the auxiliary oxygen supply pipeline 23, The breathing mask 1 and the oxygen supply chamber 4 communicate with each other through an inspiratory tube 2 and an auxiliary oxygen supply pipeline 23 respectively. The oxygen supply chamber 4 is used to provide suitable oxygen gas with oxygen content. One end of the exhalation tube 3 is connected The other end of the breathing mask 1 and the exhalation tube 3 is co...

Abstract

The invention discloses a non-lag oxygen supply ventilator system. The non-lag oxygen supply ventilator system comprises a breathing mask, an inhalation tube, an exhalation tube, an oxygen supply chamber, an auxiliary oxygen supply pipeline and an auxiliary oxygen supply pipe for opening and closing. The start-stop cylinder of the pipeline, the breathing mask and the oxygen supply chamber are respectively communicated through the inspiratory tube and the auxiliary oxygen supply pipeline, the breathing mask is communicated with the outside world through the exhalation tube, and the non-lag oxygen supply ventilator system in the present invention passes The auxiliary oxygen supply pipeline is set up, and a small amount of oxygen is supplied in the second half of exhalation, which is used to make up for the amount of oxygen required by the user during the lag time of the ventilator sensing the inspiratory flow, so as to avoid the need for the user to supply oxygen for inhalation. Lag causes inhalation to be difficult, giving users a better breathing experience. The airflow through the exhalation tube controls the start and stop of the auxiliary oxygen supply pipeline. The control is simple and convenient, and the exhalation is smoother. The auxiliary oxygen supply pipeline provides oxygen temperature Adjustable and more comfortable to breathe.

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...
