Abstract
A mouth-to-mouth resuscitation device comprising a fluid passage having a donor inlet, a patient outlet and a valve located intermediate said donor inlet and patient outlet, said valve permitting flow of air from said donor inlet to said patient outlet but preventing flow of fluid from said patient outlet to said donor inlet; face sealing means comprising a mask portion through which said fluid passage passes; and nose sealing cushion adapted to seal the nose of said patient when pressed against the underside of the patient's nose.
Claims10
A mouth-to-mouth resuscitation device comprising
- a fluid passage having a donor inlet, a patient outlet and a valve located intermediate said donor inlet and patient outlet, said valve permitting flow of air from said donor inlet to said patient outlet but preventing flow of fluid from said patient outlet to said donor inlet;
- face sealing means comprising a mask portion through which said fluid passage passes;
- and
- a nose sealing cushion comprising means for positively locating the base of a patient's nose, and means for occluding the nostrils of a patient and for receiving an inclining force adapted to incline a patient's head backwards and thereby open the airway, said means for locating the base of a patient's nose comprising sidewalls on said cushion defining a recess therebetween and said means for occluding and force receiving comprising abutment portions of said nose sealing cushion, wherein said nose sealing cushion is used to positively locate the base of the nose of a patient when pressed upwardly against the underside of a patient's nose.
A method of administering mouth-to-mouth resuscitation to a patient comprising the steps of:
- (a) applying to the face of a patient in need resuscitation a mouth-to-mouth resuscitation device comprising
- a fluid passage having a donor inlet, a patient outlet and a valve located intermediate said donor inlet and patient outlet and at least one exhaust port in said valve permitting flow of air from said donor inlet to said patient outlet but preventing flow of fluid from said patient outlet to said donor inlet;
- face sealing means comprising a mask portion through which said fluid passage passes;
- and
- nose sealing cushion having sidewalls and resilient abutment portions defining a recess therein and adapted to seal the nostrils of a patent;
- (b) pressing said device onto the face of a patient such that said mask portion seals around a patient's mouth, and pressing said device upwards such that said nose sealing cushion abuts and seals the nostrils of a patient and inclining a patient's head backwards to open the airway;
- (c) exhaling into said donor inlet to force air out of said patient outlet;
- and
- (d) allowing patient exhaled fluid to flow into said donor outlet and out of said fluid passage via said exhaust port.
