  • Patent number: 4944291
    Abstract: A device for use by an attendant performing hygienic mouth to mouth artificial respiration on a patient includes a mouth mask formed from a flexible elastomeric material configured for conforming sealing engagement over a patient's mouth. First and second tubes formed from a clear plastic material extend in sealing relation through the mouth mask. A check valve and mouthpiece are connected to the first tube for allowing an attendant to blow air into a patient's mouth, while preventing exhaled air from a patient from returning through the first tube to an attendant. An elbow and an attached flexible exhaust conduit are connected to the second tube for directing air exhaled from a patient away from an attendant. The flexible exhaust conduit may be pinched by an attendant to regulate the exhalation rate of a patient. An elongated flexible tether, formed integrally with the mouth mask, has a slotted portion through which a nose clip is inserted.
