Problems solved by technology

This mode may have the following problems: when the inspiratory phase of mechanical ventilation conflicts with compression, the airway pressure is too high, and the gas cannot enter the lungs normally; when the expiratory phase is synchronized with the chest recoil, the expiratory efficiency is reduced

Embodiment

[0023] like figure 1 Shown is a trigger-type high-frequency jet ventilator for cardiopulmonary resuscitation, including a control unit and a jet ventilation device; the jet ventilation device is connected to an artificial airway through an air circuit; the control unit is connected to a device for sensing chest rise or breathing Airflow sensing unit or artificial cardiopulmonary resuscitation machine; after the control unit receives the sensing signal sent by the sensing unit or the compression signal from the artificial cardiopulmonary resuscitation machine, it sends The jet ventilation device issues a start jet command; at the end of the thoracic rebound (ie, the beginning point of chest compression), a stop jet command is issued; the jet ventilation device starts or stops jet ventilation to the artificial airway according to the received command.

Abstract

The invention discloses a trigger type high-frequency jet ventilator for cardio-pulmonary resuscitation. The trigger type high-frequency jet ventilator comprises a control unit and a jet ventilation device. The control unit is connected with a sensing unit or an artificial cardio-pulmonary resuscitation machine used for sensing thorax fluctuations or breathing airflow. The control unit sends a jet starting instruction to the jet ventilation device from a thorax pressing end point, and sends a jet stopping instruction from a thorax springback end point. Ventilation is achieved for a patient on the condition of continuous external chest compression, the compression intermittent time is greatly shortened, ventilation can be accurately carried out in the thorax springback period of the patient, coronary artery, heart and brain instillation can be effectively improved, and therefore the patient can obtain better prognosis.

Description

technical field [0001] The invention relates to the technical field of medical ventilators, in particular to a trigger-type high-frequency jet ventilator for cardiopulmonary resuscitation. Background technique [0002] Once cardiac arrest occurs, if immediate rescue and resuscitation is not obtained, it will cause irreversible damage to the brain and other vital organs of the human body after 4 to 6 minutes. Therefore, cardiopulmonary resuscitation (CPR) after cardiac arrest This must be done immediately on site. [0003] The "International Guidelines for Cardiopulmonary Resuscitation" updated every five years formulated by the American Heart Association (AHA) and the resuscitation societies of some other western developed countries has important positive significance for guiding and standardizing cardiopulmonary resuscitation worldwide. In 2010, the American Heart Association (AHA) and the International League of Resuscitation (ILCOR) released the latest guidelines for car...
