Description
Technical Field
The utility model belongs to the lifesaving instrument field, especially, prevent drowned waistband.
Background
The existing life jacket is made of nylon fabric or chloroprene rubber, buoyancy material or inflatable material, reflective material and the like. Typically vest-style, made of foam or cork, etc. The wearer has enough buoyancy to ensure the head of the person falling into the water to be exposed out of the water.
The prior life buoy is usually made of cork, foamed plastic or other light materials with smaller specific gravity, and canvas, plastic and the like are wrapped outside the life buoy. The wearer puts the sleeve under the armpit to keep the head exposed to the water surface to maintain normal breathing. The swim ring for swimming exercise is made of rubber, plastic and other materials, and the inside of the swim ring is filled with air to ensure certain buoyancy.
Patent application document with application number CN201810835283.X discloses an intelligence prevents drowned waistband based on Android APP, wireless transmission technology and sensing technology, each sensor of this waistband installation around the waistband monitors the temperature at any time, water pressure, water depth and person's of wearing rhythm of the heart, cell-phone APP can show data such as person's of wearing rhythm of the heart in real time, when the unstable and heartbeat number of times of discovering person's of wearing rhythm of the heart data is low, the system implements the warning automatically, and remind people around and send the message for person's of wearing family and detect simultaneously that person's position of wearing reminds for near hospital. However, the main method for solving the drowning problem of the wearer is that each sensor detects certain water temperature, water pressure, water depth and the heart rate of the wearer and then transmits the water temperature, water pressure, water depth and the heart rate of the wearer to the mobile phone APP for alarming, and informs the family members, hospitals and people around the hospitals through the APP. The utility model discloses a only after the person of wearing falls into water to the external world send help seeking, if inform police, family members, hospital etc. do not make the person of wearing realize saving oneself in real time, the person of falling into water of accident is drowned death usually for drowning now, drowned person's heart stops suddenly in 2-3 minutes under the drowned condition, does not play sufficient guarantee effect to the person of wearing's life safety through external help seeking method.
Patent application No. CN201610783523.7 discloses a prevent drowned waistband, waistband main part is made with the soft sweat-absorbing material of breathing freely of cotton-flax tired, will buckle the belt lock, and waistband main part is equipped with the soft box of lifesaving, and the soft box of lifesaving comprises gas generator, microcircuit automatic control board and folding gasbag. The device is set to be in an opening mode, once the device meets water, the gas generator can feed water, when the pressure reaches a certain volume, the circuit board can open and release reactive metal of gas reaction substances, the gas guide pipe and the water inlet pipe are closed at the same time, and gas enters the folding air bag to rapidly expand the air bag; if the microcircuit control panel is invalid, also can manually pull open the safety rope, open the active metal of release gas reaction material, close water inlet and air duct simultaneously. This prevent drowned waistband, the measure of guarantee wearer's personal safety is that gas generator intakes, and when reaching certain capacity pressure, the circuit board can be opened the active metal of release gas reaction material, closes air duct and inlet tube simultaneously, and gaseous entering is folding gasbag. The device has the following defects: first, in the scheme, a gas reaction substance active metal is used, and if a leakage phenomenon occurs, the leakage of the active metal gas substance into the air can cause a pollution problem, so that the environment and the life safety of a wearer are threatened. Secondly, the scheme is that gas is generated by chemical reaction and is filled in the air bag to achieve certain buoyancy so that the head of a wearer is kept higher than the water surface, and therefore the self-rescue purpose is achieved. When the reaction conditions of the chemical reaction do not reach the standard, the problem of incomplete reaction is easy to occur, so that insufficient gas is generated, and the buoyancy generated is not enough to ensure that a wearer floats on the water surface, so that the life safety of the wearer is caused. Thirdly, the chemical reaction takes a certain time to react to generate gas, the time for filling the air bag is long, and the problem that the air bag is filled with drowned air easily is caused. Fourthly, the chemical reaction generally produces byproducts such as water, and the device has reaction residues inside after being used once, which is not beneficial to secondary use. The device needs to be replaced or cleaned during secondary use, and the cost for the wearer to use the device is too high.
