RESPIRATORY MASK

A respiratory mask includes a mask body and an air inlet connector. The mask body is formed with an air inlet. The air inlet connector is integrally formed at the air inlet. The respiratory mask can be direct connected to an oxygen tube, an air storage bag, a mist spray tank, a medicine feed tank or a standard air tube of 22 mm, without the need for a separate connector. The respiratory mask decreases the number of the parts and is easy to operate for medical workers to change different pipes, without changing the respiratory mask.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown inFIG. 1,FIG. 2andFIG. 3, the present invention discloses a respiratory mask. The respiratory mask comprises a mask body1and an air inlet connector13. The mask body1has a plurality of holes11at a circumferential portion thereof for connecting elastic straps, so that the mask body1can be attached to the face of a patient through the elastic straps. The patient can select the elastic straps in a two-way wearing manner as desired to position the mask on the head, or in a one-way wearing manner.

The mask body1is formed with an air inlet12. The air inlet connector13is integrally formed at the air inlet12. The air inlet connector13is adapted to mate with a standard connector of an oxygen tube, an air storage bag, a mist spray tank, a medicine feed tank or a standard air tube of 22 mm, so that the air inlet connector13is can be direct connected to the oxygen tube, the air storage bag, the mist spray tank, the medicine feed tank or the standard air tube of 22 mm, without the need for a separate connector. The present invention decreases the number of the parts and is easy to operate, namely, it can lower the risk of disengagement of the parts and lower the manufacture cost, it is convenient for medical workers to change different pipes without changing the respiratory mask so it can be used widely. The inner side of the air inlet12is provided with a one-way inlet valve plate2. Two sides of the mask body1are respectively formed with an air outlet14. The air outlet14is provided with an outlet valve plate so that the delivered gas is sent to the mask body1in a one-way manner for medical use to the patient and the outputted breath of the patient is discharged to outside in a one-way manner through the air outlet. This can prevent the patient from inhaling external air to lower the concentration of oxygen. That is, the present invention can prevent the outputted breath of the patient from entering the oxygen tube, the air storage bag, the mist spray tank, the medicine feed tank or the standard air tube of 22 mm to ensure consistent concentration and pressure of the delivered gas to enhance medial quality.
