| 摘要 |
The present invention is an assisted breathing device which allows a rescuer or emergency care giver to administer mouth-to-mouth type resuscitation to a victim or patient on land or in the water, without the rescuer or emergency care giver having to come in direct contact with the victim or patient's lips, exhaled air or body fluids. The assisted breathing interface device comprises, in combination, a tubular conduit or housing, a slide valve, and a spring or tension loaded valve member on the slide valve. The tubular housing has two open end orifices, at least one defined side wall opening and a central air passageway for the flow of air from a first person (rescuer or emergency aid giver) to a second person (victim or patient) during inflation or inhalation, and from the second person to defined side wall opening(s), and then the atmosphere, during exhalation; a slide valve, with at least one air passageway therein; and a valve member positioned at the air passageway in the slide valve, to control the flow of air through the air passageway on the slide valve. In operation the flow of air through the central passageway in the assisted breathing device is controlled by the slide valve and its valve member positioned at the air passageway in the slide valve, which operates to either open the passageway in the slide valve or close it, so that air can be directed through the central passageway in the device and the passageway in the slide valve from the first person to the second person as needed, but exhaled air from the second person does not return through the passageway in the slide valve to the first person.
