Problems solved by technology

[0003] These technologies solve the problem of portability of life-saving devices, but the inflation methods are very complicated. If the gas generating device is aging or malfunctions, it will not work, and these methods that rely on chemical reactions or compressed gas for inflation have hidden dangers of personal injury

Embodiment 1

[0024] Such as figure 1 , figure 2 As shown, a portable self-inflating lifesaving device includes a stretchable structural skeleton, and the structural skeleton realizes the transition between the folded or compressed state and the open state through foldable lightweight metal components and limiting holes. , the space enclosed by the structural skeleton in the open state is greater than the space enclosed by it in the folded or compressed state, and an airbag made of an air-tight, water-impermeable material, the structural skeleton is wrapped inside the airbag , the airbag is provided with a vent hole, the vent hole is provided with a one-way valve, the gas can only flow into the airbag from the outside through the one-way valve, the one-way valve is detachable; the vent hole is a long hose that can float, which can ensure When in use, the vent hole floats on the water surface to prevent the airbag from entering water; when the structural skeleton is in a folded or compress...

Embodiment 2

[0033] Such as image 3 As shown, the difference from Example 1 is that the structural skeleton in this embodiment is composed of tear-resistant fiber braided rope, which is more convenient to fold and compress as a whole. Drawstrings, pulling each drawstring will make the skeleton structure unfold and prop up the airbag, thereby inflating; the structural skeleton of this embodiment can also use a hard circle frame combined with a fiber braided rope. Other contents of this embodiment are the same as those of Embodiment 1.

Abstract

The invention belongs to the field of water lifesaving and provides a portable self-inflating lifesaving device including a retractable structural skeleton. The structural skeleton may be expanded from a folded or compressed state to an expanded state, and the space enclosed by the structural skeleton in the expanded state is greater than the space enclosed by the structural skeleton in the foldedor compressed state. The device also includes an airbag made of an airtight water-proof material, and is enclosed in the airbag, and the airbag is provided with an air vent hole provided with a ventilation switch. As that skeleton expands from a folded or compressed state to an expanded state, the airbag is also correspondingly supported by the structural framework to be in an expanded state froma folded or compressed state, when the airbag is expanded, the ventilation switch is in an open state, the external air enters the airbag through the air vent hole, the ventilation switch is closed,the air is sealed in the airbag, and the airbag can generate buoyancy in water for water rescue.

Description

technical field [0001] The invention relates to a portable self-inflating lifesaving device, which belongs to the field of water lifesaving. Background technique [0002] According to the World Health Organization, an estimated 360,000 people died from drowning in 2015 alone. Drowning is often caused by emergencies, especially floods and shipwrecks. Victims lack effective rescue tools when they encounter danger. Common rescue tools such as life jackets, buoy rings, etc. often have the disadvantages of larger volume and heavier weight. In order to overcome these defects, a series of portable water life-saving devices have been developed, such as Chinese patent CN105460181B discloses a kind of portable water life-saving device, utilizes a compressed air tank to inflate an inflatable life buoy; Chinese patent CN106043628B discloses a portable water life-saving ball, The elastic bag is inflated by using the gas and foam generated by the reaction of the foaming reaction solutio...
