Title: Oxygen mask which facilitates a pateint to breath oxygen

Description:
BACKGROUND OF THE INVENTION 
     a) Field of the Invention 
     The present invention relates to an oxygen mask which facilitates a patient to breath oxygen and more particularly to an oxygen mask which covers a nose without covering a mouth, so that more oxygen can be supplied when a patient is inhaling oxygen. 
     b) Description of the Prior Art 
     Referring to  FIG. 1 , as covering a mouth A and a nose B of a patient simultaneously, a conventional mask  100  is provided with a larger area and an imperfect bonding ability; besides, a metal piece  101  must be used to clip a nose bridge. On the other hand, as the mouth A is covered by the mask  100 , it is not convenient for treatment and as a respiration tube  102  faces downward, it is even inconvenient for the physical examination. In addition, the aforementioned respiration tube  102  is provided with two air inlets  103  which supply air to the patient simultaneously when the patient inhales oxygen from the respiration tube  102 . This oxygen inhaling method is not very helpful to the patient to inhale more oxygen. 
     SUMMARY OF THE INVENTION 
     Accordingly, the primary object of the present invention to provide an oxygen mask which facilitates a patient to breath oxygen, which covers a nose without covering a mouth, wherein a respiration tube faces upward, an air inlet tube is located at a center of an exterior side of the respiration tube and an inner tube of the air inlet tube is extended into the respiration tube. A patient breathes in oxygen from the air inlet tube and breathes out from a tube opening of an exhale tube at an upper end, so that he or she can inhale more oxygen. 
     To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

     DETAILED DESCRIPTION OF T HE PREFERRED EMBODIMENTS 
     Referring to  FIG. 2  to  FIG. 4 , an oxygen mask  10  of the present invention is small in size and only covers a nose B of a patient without covering a mouth A, the oxygen mask  10  comprises a mask  11  and a respiration tube  12 , openings at two sides of the mask  10  are tied with straps  112  to sheath the mask  10  at a patient&#39;s head, a top part at a front side is provided with a latch slot  111  to latch a respiration tube  12 . As the respiration tube  12  faces upward, a piping of the respiration tube  12  will not wind around a chest, thereby facilitating a physical examination. 
     The present invention is primarily characterized in that: 
     A transversal air inlet tube  123  is provided at a center of an exterior side of the respiration tube  12  and is extended to an inner tube  1231  inside the respiration tube  12  to be bended in an L-shape. An exhale tube  122  is located at an upper end of the respiration tube  12 . When the patient inhales, he or she breathes in oxygen from the air inlet tube  123  of the respiration tube  12  and when the patient exhales, he or she breathes out from a tube opening  1221  of the exhale tube  122 . Through repeated tests by a hospital, this oxygen inhaling method is the best to facilitate the patient breathing in oxygen and can supply more oxygen to breath in than an ordinary respiration tube. 
     Conclusive from the above, the present invention provides an oxygen mask which facilitates a patient to breath oxygen, which covers the nose without covering the mouth, wherein a respiration tube faces upward, an air inlet tube is located at a center of an exterior side of the respiration tube and an inner tube of the air inlet tube is extended into the respiration tube. A patient breathes in oxygen from the air inlet tube and breathes out from a tube opening of an exhale tube at an upper end, so that he or she can inhale more oxygen.
