A device is constituted by an inflatable neck float (1), with a U shape placed around the neck and closed by a safety closure (2) to allow perfect fitting around the neck, inside said neck float (1) there is a flexible tube (3) that carries a gas (11), introduced in liquid state and which, upon being released suddenly, will expand and inflate the lifesaving neck float.

A self-inflating water rescue device (1) consisting of a belt (2) for fastening to the waist and a lifebelt (5) connected to a compressed gas cartridge (4) attached to an opening trigger (3), the belt (2) and the lifebelt (5) being connected to each other by a safety strap (9), one end of a release cord (11) is connected to the opening trigger (3), the other end of the cord (11) being routed outside the lifesaving device (1), the lifebelt (5) being provided with a release valve (12) where applicable, and characterized by that a storage pocket (8) is formed on at least a part of the outer side of the belt (2) by a fixed wall (6) and an sliding (loose) wall (7), the lifebelt (5) being arranged in the storage pocket (case) (8), the outer part of the belt (2) being itself a fixed wall (6) of the pocket (8), the lifebelt (5) has a basically interrupted perimeter circle shape, the ends (13) of which at the interruption are overlapping when filled with gas, and when not filled with gas the lifebelt (5) is folded into the pocket (8) in an accordion/fan-like manner.

A floatation device is provided. In some embodiments, a floatation device is provided, comprising an inflatable ring composed of a transparent material, wherein the inflatable ring includes: an outer air chamber having a first valve for inflating the outer air chamber; an inner air chamber having a second valve for inflating the inner air chamber, wherein the outer air chamber and the inner air chamber are not in communication; a cut through the outer air chamber and the inner air chamber of the inflatable ring that forms opposing ends of the inflatable ring; and a plurality of fasteners placed on a top surface and a bottom surface of the outer or inner air chamber for detachably connecting the opposing ends of the inflatable ring.

A life preserver (1) including an inflatable main body portion (3) having an aperture (5) for a wearer's neck, and first and second inflatable lobes (7, 9) extending from the main body portion which are configured to respectively occupy a position on the left and right hand side of the wearer's body when in use. The main body portion may be formed by corresponding front and rear layers of material that are connected around their outer peripheries and which each have an aperture for the wearer's neck, wherein the main body portion further comprises an additional layer of material that is connected to the front and rear layers of material around the apertures in the front and rear layers to form a surface that, upon inflation of the main body portion, encircles the wearer's neck. A panel (15) of material mounted on a front surface of the main body portion adjacent to, or partially overlying, the neck aperture may protect the wearer's airways from water splashes.

An inflatable flotation device having a reaction chamber with reactants that generate gas when mixed, said reactants being separated by a barrier assembly; an activating mechanism adapted to remove or puncture the barrier assembly such that said reactants mix; and an inflatable compartment fluidly connected to the reaction chamber by means of a pressure sensitive passageway, adapted to open only when the pressure of the gas in said reaction chamber exceeds a predetermined threshold. This ensures that most of the reactants are used up to generate gas before the gas enters the inflatable chamber, thus preventing scattering of the reactants. Some implementations have a reaction chamber without a barrier assembly, comprising reactants that generate gas when mixed with water and an activating mechanism adapted to expose the reactants to water. A variety of manual or automatic mechanisms may be employed to activate the reaction and inflate the device.

A lifesaving device and a lifesaving control method are provided. Wherein, the lifesaving device includes: at least one first detection module (200) configured for detecting human body biological characteristic information, a lifesaving device body (100) capable of being worn on a body of a user, and at least one first gasbag module (300) arranged on the lifesaving device body (100); after the first gasbag module (300) is activated, a lifesaving gasbag (1) can be popped up; the first detection module (200) is in signal connection with the first gasbag module (300) and is configured for activating the first gasbag module (300) when the biological characteristic information detected meets a first preset condition.

A floatation device for use by an individual in a body of water, comprising of an upper body covering and two fabric covered inflatable sleeve elements. The upper body covering contains multiple gussets that hide the male or female end of a clasp device. The fabric covered inflatable sleeves contain the opposite end of the clasp device which allow them to be securely fastened to the upper body covering in one or more locations.

An anti-drowning apparatus configured to inflate a balloon when a swimmer with the apparatus is submerged to an unsafe depth so as to help the swimmer return to the surface. The 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.

A flotation device for providing emergency flotation for a person swimming or passing through a body of water, comprising a container filled with a charge of a gaseous material under a pressure such that it is in its liquid phase at normal environmental temperatures. The container is connected to a flexible flotation chamber through a passage which remains normally closed until actuated by the user. When the device is actuated by opening the passage, the charge expands into the flotation chamber, thereby inflating it, and providing support to the user in the water. The gaseous material has thermodynamic properties such that it remains in its liquid phase right up to the maximum temperatures to which the device is expected to be exposed to. Consequently, its volume, and hence the internal pressure within the gas container, does not increase significantly, thereby enabling the container to be of lightweight construction.
