氧气面罩

Oxygen mask
Abstract:
An anatomical shaped oxygen face mask with ports allows medical procedures to take place while the mask remains affixed to patient's face covering both mouth and nose. The mask is specially designed to allow the patient to ventilate spontaneously while at the same time allowing access for instruments by means of ports located at the front of the mask. One port may be used for procedures while another port can be used for suctioning of secretion and blood or for providing oxygen.
