| Abstract: |
A shield for use in mouth-to-mouth or mouth-to-nose resuscitation. The shield is constructed of a one piece sheet of thin flexible material capable of assuming complimentary sealing relationship over a patient's face and includes dimensions sufficient to cover the face from ear-to-ear and from the bridge of the nose to the bottom of the chin. The shield includes a mouth opening located substantially centrally thereof and adapted to fit over a patient's mouth to permit air to be blown therethrough into the patient's lungs in mouth-to-mouth resuscitation. A lip flap can be optionally provided around the periphery of the mouth opening and a second opening can be provided in spaced relationship with the mouth opening for use in mouth-to-nose resuscitation.

I claim:
1. A device for use in mouth-to-mouth, mouth-to-trachea or mouth-to-nose resuscitation comprising a one piece sheet of thin flexible material capable of assuming complementary sealing relationship over the contour of a person's face and of sufficient dimensions to cover the face in the mouth and nose area and including an unobstructed opening located substantially centrally of said sheet and sized to be operably positioned over a patient's mouth, trachea or nose whereby an effective seal can be made between said patient's mouth, trachea or nose and a rescuer's mouth through the portion of said sheet surrounding said opening when said rescuer presses his mouth against said patient's mouth, trachea or nose through said sheet to prevent air escape around said patient's mouth, trachea or nose and to permit air to be blown therethrough into said patient's lungs in mouth-to-mouth, mouth-to-trachea, or mouth-to-nose resuscitation.
