An oxygen mask 10 which covers the nose without covering the mouth is connected externally to a resuscitation bag and facilitates a patent to breath oxygen. An opening of a respiration tube 122 faces upward and is in an L-shape to facilitate connecting externally with the resuscitation bag. An air inlet tube 123 is located on the exterior side of the tube and an inner tube of the air inlet tube is extended into the tube. When the tube is connected externally with the resuscitation bag, the patient breathes in oxygen from the opening of the respiration tube and breathes out from the opening of the respiration tube, so that he or she can inhale more oxygen. The inner bottom of the mask close to the nostrils is provided with a number of pillars, channels or grooves 113 to prevent that a paramedic puts the mask close to the nostrils of the patient carelessly, thereby assuring the patient may breathe smoothly. |
