The beneficial effects of the utility model are in that: 1. cardio-pulmonary resuscitation or other rescue scene: also can grasp by simply training non-medical personnel, can ensure that the air flue of patient continues unobstructed, improve the aeration condition of patient, and enable rescuer to vacate hands, implement other such as important process such as defibrillation, injection, improve salvage success rate.
2. intensive care unit: for wearing the patient of noninvasive ventilator, it is ensured that respiratory tract lasting unobstructed, it is ensured that oxygenate, makes some patients avoid stimulating bigger tracheal intubation.
3. anesthesia: in patient mask's aeration stage, particularly doctor's hands is little, short wind, persistently force are inadequate and patient's face mask situation big, muscular, utilizes this device to connect respirator, ensures that patient continues airway open, ensure alveolar oxygen supply, reduce the incidence rate of anoxia. During difficult airway, this device can be used in combination with oropharyngeal airway or nasopharyngeal air duct.
4. this device noinvasive uses, and can remove oropharyngeal airway, nasopharyngeal air duct, tracheal intubation etc. to the stimulation of patient and sense of discomfort.
Mask ventilation is on-the-spot, and mask air bag face is placed on the face close contact of patient by doctor, utilizes and holds up lower jaw formula face shield bilateral hook, firmly tangles bilateral lower jaw, lift bilateral hook, makes lower jaw to lifting up (lifting on lower jaw, prognathism). Because of mask body and face shield hook one, the lift of face shield clevis arm can reversely be applied to mask air bag pressure makes face shield and oral-nasal perimeter more airtight, it is maintained with head to stretch, fully to open pharyngeal cavity space, keep respiratory passage unblocked, connecting the respiratory organ such as respirator, breathing bag and carry out Breathing Suppotion, during difficult airway, this device can be used in combination with oropharyngeal airway or nasopharyngeal air duct.
