Respirator

Abstract

The invention discloses a respirator, which comprises an oxygen therapy system and a breathing mask, wherein the breathing mask is connected with the oxygen therapy system, and can press over a face respiratory organ of a rescue receiver through being driven by a press-down mechanism. During CPR (cardiopulmonary resuscitation), the artificial respiration and the external chest cardiac compression are cooperated; after each external chest compression period is completed, the breathing mask presses over the face of the rescue receiver; oxygen gas is conveyed to the mouth and the nose of the rescue receiver through the breathing mask; the oxygen quantity of oxygen therapy to the rescue receiver is increased; and meanwhile, the workload of a rescuer can be reduced. In addition, the respirator also has the following two functions: 1, the respirator can replace a common-use artificially opened airway; and 2, a chest compression counting mechanism can accurately record the number of thoracic compression times, can report the number after each time of thoracic compression to control the external chest compression frequency, can automatically press down the breathing mask after the completion of each chest compression period, and can automatically extruding a breathing bag twice, so that the cooperation of the chest compression and the oxygen intake is accurate.

Description

technical field [0001] The present invention relates to a respirator. Background technique [0002] Simple breathing airbag is a commonly used first aid tool, suitable for 1. Acute respiratory failure occurs when breathing stops or weak breathing does not improve after active treatment. Significantly insufficient pulmonary ventilation. 2. Patients with chronic severe respiratory failure who have not improved after various treatments or have pulmonary encephalopathy, before using the ventilator or when the ventilator is stopped. 3. When artificial respiration is required for cardiopulmonary cerebral resuscitation. The simple breathing air bag currently used is to let the air enter the lungs rhythmically by hand, and then use the elastic retraction force of the thorax and lung tissue to exhale the gas entering the lung, artificially squeeze the breathing bag and artificially open the airway, especially During cardiopulmonary cerebral resuscitation, it is necessary to contin...

2. Chronic severe respiratory failure, no improvement after various treatments or pulmonary encephalopathy, before using the ventilator or when the ventilator is stopped

The simple breathing air bag currently used is to let the air enter the lungs rhythmically by hand, and then use the elastic retraction force of the thorax and lung tissue to exhale the gas entering the lung, artificially squeeze the breathing bag and artificially open the airway, especially During cardiopulmonary cerebral resuscitation, it is necessary to continue to open the airway manually during each chest compression, and cooperate with the chest compression provider to give artificial respiration to the rescued person. The ratio of chest compressions to insufflations is generally 30: 2. For the rescuers of manual cardiopulmonary cerebral resuscitation, both chest compression and air blowing are required. The workload is heavy, and they are easily fatigued, so it is very difficult to implement
