Abstract
An anti-drowning apparatus configured to inflate a balloon to provide emergency flotation when a swimmer with the anti-drowning apparatus is submerged to a selected depth so as to help the swimmer return to the surface. The anti-drowning apparatus may be integrated into a swimming garment. An integrated emergency flotation apparatus may also include a manual pump configured to inflate a compression port used to store compressed air for inflating the balloon.
Claims20
An anti-drowning apparatus, comprising:
- a compression port configured to store compressed air;
- an inner tube slidably engaged with an outer tube, each of the inner and outer tubes having respective apertures formed therein, wherein compressed air stored in the compression port is expelled into a flotation balloon when the inner tube apertures and outer tube apertures are aligned;
- a spring disposed between a proximate end of the outer tube and a proximate end of the inner tube to urge separation of the proximate end of the outer tube and proximate end of the inner tube such that the inner tube apertures and outer tube apertures are not aligned;
- and
- a water pressure responsive mechanism configured to urge the inner tube toward the spring in response to an increased level of water pressure imparted thereto, wherein a water pressure level associated with a selected depth is sufficient to cause compression of the spring such that the inner tube aperture and outer tube aperture become aligned such that the flotation balloon is inflated.
