According to the present invention, when people fall into water of low water temperature, such as winter, when the water falls to reduce the body temperature of the drowned person, and falls into the water to reduce the loss of life of missing persons, death due to temperature decrease by the heating element attached inside the life jacket This is a technical idea to prevent human injury.

In order to realize the above technical idea, in the present application, a life jacket including a buoyancy material and a heating element is mounted on the inside of the front part and the rear part of the life jacket wearer's chest and the back part so that the heating element is not normally operated, and in case of emergency It is possible to provide a life jacket equipped with a heating element to reduce the human injury caused by the body temperature decrease of the learner by the exothermic reaction of the heating element by artificial manipulation of the learner.

The life vest can be classified into a method of providing a tube in the space between the inner shell and the outer shell, injecting air therein, and installing a buoyant material made of foamed resin between the inner shell and the outer shell. Life vests are generally used to float a wearer by using their own buoyancy, and are used by passengers such as boats or boats to safely float inexperienced people in the water or in preparation for a water disaster. In particular, as water leisure sports are becoming more popular in recent years, they are used not only for motor boats but also for water skiing and water rides, which are used to prevent the occurrence of water safety accidents. Most water leisure and water rides are enjoyed when the temperature is warm in summer, but when it comes into contact with water for a long time due to circumference, the water temperature is lower than the body temperature. In particular, even when wearing a life jacket during the marine abalone accident during the winter, the temperature of the sea water is very cold, the water has a higher thermal conductivity than the air, and the flow of sea water is so rapid that it takes away the heat of the human body at a very high speed to accelerate the hypothermia.

Hypothermia means that the body temperature is below 35 ℃, and under hypothermia, mental function is slowed down, muscle strength is lost, pulse and breathing is weak, blood pressure decreases, and when the body becomes severe, the body becomes like ice. It cools and the skin loses its vitality and becomes pale. Especially, if the body temperature falls below 26 ° C, the coma falls into coma and eventually loses life.

In order to provide a better life jacket, Korean Laid-Open Patent 2003-0087848 proposes a life jacket that maximizes safety by allowing a wearer to float in the vertical direction in water, and in Korean Laid-Open Patent 2003-0023748, a buoyancy member is not required. The life vest has been proposed to reduce the volume of the buoyancy body to reduce the volume of the buoyancy body while shrinking the contraction, so that carrying, storage and handling is very easy, Korean Patent Laid-Open Publication No. 2003-0086494 By using an inner belt that tightly tightens, life jackets can be effectively attached to the wearer's body underwater even without using a leg support belt, and life jackets that can be worn appropriately for various body sizes and various body shapes of the wearer I'm proposing.

The methods proposed in the above patents only reduce the possibility of drowning accidents for buoyancy, and make a small proposal for a more convenient and safe life jacket, even though an environment capable of breathing by wearing a buoyant life jacket with excellent buoyancy. However, there is no suggestion of a technique that can reduce the damage caused by the body's hypothermia in the cold state of the body encroached water.

Therefore, an object of the present invention is that if people fall into water of low water temperature, such as winter, when the water falls to reduce the body temperature of the drowned person to reduce the death or disappearance of life loss, the chemical heating of the heating element by artificial operation of the drowned person It is to provide a vest equipped with a heating element to prevent the body temperature lowered by the heating element attached to the inside of the life jacket by the reaction to prevent human injury such as death by the temperature lowering. Another object of the present invention is to provide a vest equipped with a heating element for preventing the damage of hypothermia of people in a cold aquatic environment with high possibility of hypothermia.

Life jackets are worn on the upper body to reduce the casualties of people unfamiliar with the water, and generally means equipment to float the wearer on the water using its own buoyancy. Conventional life jackets include a front portion surrounding the chest and abdomen of the body, a back portion surrounding the back portion with respect to the front portion, and a buoyancy material provided respectively inside the front portion and the rear portion. That is, the front part and the rear part are divided into an inner skin and an outer skin, respectively, and a buoyant material of a foamed resin is inserted between the inner skin and the outer skin, or an air injection type for injecting or discharging air.

The present invention is equipped with a heating element in the above-mentioned life jacket, when people fall into the water of low water temperature, such as winter, the artificial body of the cooker prevents the loss of body temperature by chemical exothermic reaction by lowering the body temperature due to chemical exothermic reaction of death and missing It aims to reduce casualties.

In addition, the belt (7) connected to the buckle is connected to both sides of the front part (1) to maintain the wearing state of the life jacket more firmly, and is configured to loosen and reduce the belt according to the waist circumference of the wearer, The present invention is not limited thereto, and a detachable and convenient device can be used, and any life jacket can be applied if the life jacket is firmly worn on the upper body.

Life jackets can be injected here by providing a tube in the space between the endothelium and the outer shell, and there is no restriction in constructing a buoyant material made of foamed resin between the inner and outer shells, Since it has a disadvantage to be injected, it is advantageous to be composed of a buoyancy material made of a foamed resin, the buoyancy material is advantageously composed of a cross-linked foam of polyolefin (polyolefin) or polyethylene to have a lot of buoyancy with a low specific gravity. The inner and outer skins located on both sides of the buoyancy member can use a waterproof material to increase buoyancy, and it is advantageous to use a jersey material with good touch because the inner jacket of the life jacket can directly contact the wearer's skin. However, when the heating device of the present invention is mounted inside the life jacket, the part in contact with the skin does not have to be limited to the heating element of the present invention.

The heating element in the life jacket equipped with the heating element of the present invention is a heating composition that generates an exothermic reaction by oxidation of a metal in contact with water, and the heating element of the heating element generates heat by using heat when metal powder, which is a heating material, is oxidized. The composition is composed of an exothermic substance, a reaction accelerator, an essential component of water and a carbon component, and an auxiliary component of a super absorbent resin, a pH adjuster, and a hydrogen generation inhibitor. The exothermic composition of the present invention should use a sealed pack that does not normally contain moisture, so that a person wearing a life jacket in an emergency can easily supply moisture through a method of artificially cutting to prevent low body temperature due to the exothermic reaction accordingly. do.

Hereinafter, an embodiment using the present invention will be described. The embodiments disclosed herein are intended to clarify the interests of the present invention, but the present invention is not limited thereto.

Example 1

5 parts by weight of activated carbon, 10 parts by weight of sodium chloride, and 2 parts by weight of polyacrylate-based superabsorbent resin were uniformly mixed based on 100 parts by weight of iron, and a heating element sheet was prepared to have an average thickness of 1 cm using a nonwoven fabric. Wear a life jacket equipped with a heating element on a mannequin by attaching it to a conventional life jacket, install a thermometer on a part where the surface of the mannequin and the heating element of the present invention are in contact with each other, and then obtain an aquarium to obtain a heat generation temperature and a temperature holding time. The average value measured 5 times was shown as a result of this invention. At this time, the average particle size was less than 100 ㎛, the average temperature in the water was 9.6 ℃.

Example 2

An average thickness of the sheet of the heating element using the nonwoven fabric was prepared in the same manner as in Example 1 except that the average thickness of the sheet was manufactured at 2 cm.

Example 3

Except for using magnesium powder instead of iron as a heating material was carried out in the same manner as in Example 1.

Example 4

Except that the average thickness of the sheet of the heating element using a nonwoven fabric 2 cm was carried out in the same manner as in Example 3. Table 1 shows the results of Examples 1 to 4.

TABLE 1

Although the temperature in the water in Examples 1 to 4 maintained a cold temperature of 9.6 ° C., the temperature of the back surface of the mannequin can be maintained at about 39 ° C. or more for about 2 hours through the present invention. It was found that it can prevent human injury such as loss of consciousness, coma and death.

When magnesium powder was used as an exothermic material, the temperature was further increased. This is because magnesium is more oxidized than iron, and it can be seen that the temperature holding time is relatively increased as more heating materials are included in the heating element sheet. Therefore, it turned out that content in a heat generating sheet can be adjusted and used according to the use.

Conventional life vests reduce the likelihood of asphyxiation due to immature swimming of swimmers and are only making fine proposals for more convenient and safe life vests, even though they can breathe life jackets with excellent buoyancy. Even if the environment was provided to prevent the asphyxiation, it had a disadvantage of not protecting human life due to hypothermia caused by low water temperature.
