Claims
- 1. A medical device for enabling a rescuer to administer mouth-to-mouth resuscitation to a victim while maintaining a sanitary barrier between victim and rescuer, comprising:
- a sheet of a flexible material forming a barrier to micro-organisms, said sheet being dimensioned to completely cover the victim's mouth, said sheet having an opening and a shaped portion of circular form which surrounds said opening and is shaped to allow the rescuer's lips to form an air-tight seal with the victim's lips when the rescuer is blowing air into the victim's mouth, said sheet, including said shaped portion, being formed to permit the victim to exhale without obstruction when the rescuer's lips are withdrawn from said sheet;
- a tubular member defining a confined air passage extending through said opening and having a first portion located to be inserted into the victim's mouth and over the victim's tongue when said sheet is in place and a second portion located to be inserted into the mouth of the rescuer; and
- means defining a one-way valve fastened to said first portion of said tubular member for permitting free passage of air only from the rescuer to the victim.
- 2. A device as defined in claim 1 further comprising means surrounding said valve and serving as a barrier between said valve and a victim's tongue when said first portion of said tubular member is inserted into the mouth of the victim for preventing the victim's tongue from obstructing said valve.
- 3. A device as defined in claim 1 wherein said shaped portion of said sheet which surrounds said opening comprises a frustoconical portion surrounding said tubular member to a form a seal with the victim's lips.
- 4. A device as defined in claim 3 wherein said sheet, said tubular member and said valve are constituted by a one-piece molded member.
- 5. A device as defined in claim 4 wherein said molded member is of a silicone rubber.
- 6. A device as defined in claim 1 further comprising a second tubular member of a rigid material held in place relative to said first-recited tubular member to surround the air passage, said second tubular member serving as a bite block to prevent the victim from closing the air passage.
- 7. A device as defined in claim 1 wherein said first portion of said tubular member is of a length to cause said valve to be located above the tongue of the victim when said first portion is inserted into the victim's mouth and to not induce vomiting by the victim.
- 8. A device as defined in claim 1 wherein said means defining a one-way valve are constituted by two planar members which contact one another along a line perpendicular to the air passage when said valve is closed, said planar members being moveable away from one another when the air pressure in said air passage is higher than that in the region exterior to and adjacent said valve.
- 9. A device as defined in claim 1 wherein said sheet, said tubular member and said one-way valve are constituted by a one-piece molded member.
- 10. A device as defined in claim 9 wherein said molded member is made of a silicone rubber.
- 11. A device as defined in claim 10 wherein said valve is made of a 50 Durometer silicone rubber.
- 12. A device as defined in claim 1 further comprising attachment means attached to said sheet for securing said device in place on the victim.
- 13. A device as defined in claim 1 wherein said sheet is dimensioned to cover the victim's nostrils.
