Abstract
Abstract A compact, disposable mouth-to-mouth resuscitation device that comprises: a rigid yet flexible thin plastic valve body that is provided with at least one valve port, and a first thin flexible plastic sheet that is disposed on that side of the valve body that is adapted to face the mouth of the subject on which the device is to be used. This plastic sheet is provided with slits to form at least one first valve flap, the number of which correspond to the number of valve ports. The valve flaps are hinged to the plastic sheet and cover the valve ports when the device is not being used. A second thin flexible plastic sheet can be disposed on the other side of the valve body, with this plastic sheet also being provided with slits to form valve flaps, the number of which also correspond to the number of valve ports. A foam element having a central opening can be disposed on the first plastic sheet remote from the valve body.
