Embodiment 1

[0030] refer to figure 1 , a method for supplying oxygen by a compensating ventilator, comprising the following steps:

[0031] S1: When inhaling, the main oxygen supply pipeline and the auxiliary oxygen supply pipeline work at the same time;

[0032] S2: When the exhalation starts, stop the oxygen supply from the main oxygen supply pipeline and the auxiliary oxygen supply pipeline, and resume the oxygen supply from the auxiliary oxygen supply pipeline when the exhalation weakens;

[0033] S3: When inhaling, open the main oxygen supply pipeline, and the main oxygen supply pipeline and the auxiliary oxygen supply pipeline work simultaneously.

[0034] The oxygen supply method of the ventilator in this embodiment provides a small amount of oxygen supply in the second half of exhalation by setting the auxiliary oxygen supply pipeline, which is used to make up for the amount of oxygen required by the user during the lag time of the ventilator inducing the inspiratory flow. Avoid...

Embodiment 2

[0036] This embodiment proposes a ventilator based on the compensation ventilator oxygen supply method in Embodiment 1. refer to figure 2 , the ventilator comprises a breathing mask 1, an inspiratory tube 2, an exhaling 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 communicates with the auxiliary oxygen supply pipeline 23 through the inspiratory tube 2 respectively. The oxygen supply chamber 4 is used to provide suitable oxygen gas with oxygen content. One end of the exhalation pipe 3 is connected to the breathing mask 1. The other end of the tube 3 is connected to the outlet tube 32 , and the breathing mask 1 communicates with the outside world through the exhalation tube 3 . The inside of the breathing mask 1 is provided with an inhalation flow sensor, and the inhalation pipe 2 is provided with an ele...

Abstract

The invention discloses a compensation type ventilator oxygen supply method and the ventilator, wherein the compensation type ventilator oxygen supply method comprises the following steps: when inhaling, the main oxygen supply pipeline and the auxiliary oxygen supply pipeline work at the same time; , stop the oxygen supply of the main oxygen supply pipeline and the auxiliary oxygen supply pipeline, and resume the oxygen supply of the auxiliary oxygen supply pipeline when the exhalation weakens; when inhaling, open the main oxygen supply pipeline, and the main oxygen supply pipeline and the auxiliary oxygen supply pipeline work at the same time. The ventilator oxygen supply method in the present invention and the ventilator provide a small amount of oxygen in the second half of exhalation by setting the auxiliary oxygen supply pipeline, which is used to make up for the oxygen required by the user during the lag time of the ventilator inducing the inhalation airflow To avoid the situation that the user should be struggling to inhale due to the lag of inhalation and oxygen supply, and to give the user a better breathing experience.

Description

technical field [0001] The invention relates to the technical field of ventilators, in particular to a compensation type ventilator oxygen supply method and the ventilator. 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 e...
