Description

Life vest {Life vest}

The present invention relates to a life jacket, and in particular, in an emergency situation of falling into water, a tube wrapped around the neck expands to prevent the wearer's head from being submerged in water, and at the same time, heat generated from the tube is applied to the neck to prevent hypothermia. It also relates to a life jacket that prevents the wearer from losing consciousness by applying a low frequency around the neck.

BACKGROUND OF THE INVENTION A life jacket is worn to prevent a safety accident by being worn when water sports, water sports, fishing, etc., or to prevent a drowning accident in the event of a maritime accident of a ship.

When a person falls into the water and time elapses, many deaths due to hypothermia occur. Recently, many structures have been proposed to prevent hypothermia by allowing life jackets to generate heat.

As an example, in Registered Patent No. 10-2275204 (life jacket for delaying hypothermia), a vest body consisting of a left front part, a right front part, a rear part, a sleeve part and a collar part covering the user's upper body, and the left front part In the life jacket including a belt member connecting the right front part and an air bag built into the vest body to provide buoyancy, it is located on the left front part of the vest body, but is provided with a first inlet through which water flows in, , A first heating element that generates heat by reacting with water introduced through the first inlet; It is located in the right front part of the vest body, and is provided with a second inlet through which water flows in, reacting with the water flowing in through the second inlet to generate heat, and generating heat at the end of the heating duration of the first heating element. A second heating element configured to be; And it is located on the rear part of the vest body, and is provided with a third inlet through which water flows in to generate heat by reacting with the water flowing in through the third inlet, so as to generate heat at the end of the heating duration of the second heating element. A third heating element configured; including,

The first heating element is connected to the air bag, and hot air generated in the process of generating heat from the first heating element flows into the air bag to provide a buoyancy function of the air bag and to delay the loss of the user's body temperature. is composed of

The second heating element and the third heating element are connected to the air bag, respectively, and when the air introduced into the air bag is discharged to the outside due to the heat generated by the first heating element, the second heating element and the third heating element generate heat. It is configured so that the hot air generated during the process is introduced into the air bag, and the first, second, and third heating elements are sequentially heated while the user is in the water to delay the loss of body temperature of the user who has fallen into the water. The sleeve part prevents water from entering the inside of the vest body, and prevents water introduced into the inside through the lower part or collar part of the vest body from escaping into the sleeve part, thereby circulating the water flowing into the inside of the vest body. It is made in the form of an elastic band that is closely worn on the user's arm to minimize it.

Therefore, by configuring a plurality of heating elements to heat up sequentially while the user is in the water, it is possible to delay the body temperature loss of the user who has fallen into the water as much as possible. It has the advantage of minimizing the death of the user due to hypothermia in which unconsciousness is lost.

However, according to this prior art, a plurality of heating elements are sequentially heated so that the air heated by the heat circulates inside the life jacket, thereby having a structure that heats water introduced between the wearer's body and the life jacket, thereby making the structure It is very complicated and has a very inefficient structure because it delays the loss of body heat by raising the temperature of water by heated air.

In addition, when the wearer falls into the seawater, it is very difficult for the rescue team to easily detect with the naked eye in the open sea, and when the heat generation of the heating element ends due to the delay in the rescue time, there is a risk of hypothermia again.

In addition, when the wearer loses consciousness, even if the wearer is wearing a life jacket, the head part is submerged in water, and a drowning accident may occur.

The controller controls the expansion agent storage unit to inject an expansion agent into the tube to inflate it when water is sensed from the water sensor for a predetermined period of time or a value greater than or equal to a set value is input from the gyro sensor, According to the wearer's body temperature sensed by the sensor, power from the battery is supplied to the heating element to transfer heat to the wearer's neck, and the dye container is controlled so that the dye is discharged to the outside. When the body temperature of the wearer is lowered below a set temperature, the low frequency generator is driven to supply low frequency to the electrode so that the wearer's neck provides a low frequency.

In addition, a pressure sensor is provided inside the tube, and the controller controls the expansion agent storage unit to stop the supply of the expansion agent to the tube when the pressure detected by the pressure sensor exceeds a set pressure.

And, the controller operates to control the battery to adjust the power supplied from the battery to the heating element according to the state of the wearer's body temperature detected by the body temperature sensor.

According to the present invention configured as described above, when the wearer falls into water, buoyancy is applied to the tube to prevent the wearer's head from being submerged in water, and the tube wraps around the neck to transfer the generated heat to the neck, resulting in a simple structure. It is possible to maintain the body temperature of the wearer for a long time by preventing hypothermia and to prevent loss of consciousness due to low-frequency stimulation, thereby significantly increasing the possibility of survival.

In addition, since the dyeing agent is released and spreads around the wearer, the wearer's position can be easily determined with the naked eye, so it has the advantage of enabling a quick rescue.

The above objects, features and advantages will be described later in detail with reference to the accompanying drawings, and accordingly, those skilled in the art to which the present invention belongs will be able to easily implement the technical spirit of the present invention.

In describing the present invention, if it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the subject matter of the present invention, the detailed description will be omitted.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

However, the embodiments of the present invention exemplified below may be modified in many different forms, and the scope of the present invention is not limited to the embodiments described below.

The embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art.

Figure 1 is a diagram showing the structure of the life jacket according to the present invention, Figure 2 is a diagram showing the state of wrapping the wearer's neck when the tube is inflated, Figure 3 is a heating element, a low-frequency electrode, and a body temperature sensor provided in the tube It is a diagram showing the status.

And, FIG. 4 is a circuit block diagram provided in the life jacket, and FIG. 5 is a graph showing a state in which the amount of heat generated by the heating element is adjusted according to the body temperature of the wearer.

As shown in FIG. 1, the life jacket 100 according to the present invention is composed of a front plate 101 located on the front part of the wearer's torso and a back plate 102 located on the wearer's back, and the front plate 101 ) and the upper portion of the rear plate 102 are connected to each other, and both side surfaces of the front plate 101 and the rear plate 102 are open.

In addition, a band-shaped fastening part 110 for connecting and fixing the front plate 101 and the rear plate 102 to each other is provided on both sides of the open side, and the front plate 101 and the back plate 102 ) is connected, a circular head exposure hole 120 is formed so that the wearer's head can be exposed.

Therefore, such a life jacket 100 is worn by the wearer from above the head to expose the head to the upper side through the head exposure hole 120, and to expose both arms to the open both sides, and the fastening part 110 has both arms Located on the lower side of the exposed portion, the front plate 101 and the back plate 102 are in close contact with the wearer's torso, thereby preventing the life jacket 100 from being separated from the wearer.

A ring-shaped tube 130 is fixed and integrally provided around the circumference of the head exposure hole 120, and when an expanding agent is introduced, the tube 130 inflates to surround the wearer's neck while closely contacting the circumference. It rises to form buoyancy and supports the neck so that the wearer's head is not submerged in water.

That is, drowning can be prevented by supporting the neck so that the wearer's neck is not bent when the wearer loses consciousness.

As shown in FIGS. 2 and 3, the tube 130 is provided with a heating element 131 fixed along the inner circumference of the area in contact with the neck of the wearer, the heating element 131 is formed of a planar heating element will be attached

The radiator 131 generates heat by receiving power from the battery 140 provided on the front plate 101 or the back plate 102 of the life jacket 100, so that the tube 130 in close contact with the wearer's neck ) to apply heat directly to the neck.

Since arteries are exposed under the skin in the human neck and are greatly affected by external temperature, the body temperature is easily lowered when the neck is exposed. This, when heat is supplied to the neck, can prevent the temperature of the blood circulating in the human body from rapidly lowering, thereby greatly reducing the risk of hypothermia.

In other words, if the neck is kept warm by the muffler at a low temperature in winter, it is the same effect as preventing the body temperature from lowering while feeling less cold.

Therefore, it is a structure that is much more efficient than maintaining body temperature by heating the entire life jacket with high-temperature heat generated by a heating element having a complicated structure as in the prior art and heating water between the heated life jacket and the body.

On the other hand, electrodes 133 and 134 for applying low frequencies are exposed on the inner circumference of the tube 130, which stimulate the wearer not to lose consciousness by applying low frequencies to the wearer's neck.

That is, since the inner side of the tube 130 is in close contact with the wearer's neck when inflated, low frequencies can be applied through the electrodes 133 and 134.

In addition, a contact body temperature sensor 135 is further provided on the inner surface of the tube 130 to detect the wearer's body temperature, and a pressure sensor 260 is provided on the inner side of the tube 130 to measure the expansion pressure of the tube. come to sense

In addition, the dye container 150 is fixed to the front plate 101 or the rear plate 102 of the life jacket 100 while being exposed to the outside. The dye stored in the dye container 150 is a fluorescent material. It is mixed, and it is orange, white, etc. so that it can be easily identified in the bath in the lake or the sea.

In addition, in the life jacket 100, as shown in FIG. 4, the controller 200, the paint sensor 210, the gyro sensor 220, the expanding agent storage unit 230, and the driving unit 240 for opening the dye container 150 , The circuit unit composed of the low frequency generator 250 is installed.

This circuit unit may be supplied with power from the battery 140 or may be supplied with power through a battery for a separate power supply, a solar cell, or the like.

The water sensor 200 is for detecting a state in which the wearer is in water, and a conventional water sensor may be used. For example, when two electrodes are placed side by side and water flows between the two electrodes, electricity Conduction can occur and can be a means of detecting water.

The gyro sensor 220 is for detecting a rapid positional change when the wearer falls from a rock or a ship into a lake or sea.

The expanding agent storage unit 230 stores an expanding agent for inflating the tube 130, and the driving unit 240 operates to open the dye container 150.

In addition, the low frequency generator 250 oscillates a low frequency and supplies it to the electrodes 133 and 134 to stimulate the wearer not to lose consciousness.

The operation of the present invention having such a structure will be described.

First, when the wearer falls into the water while wearing the life jacket 100 of the present invention, the controller 200 receives a signal detected by the paint sensor 210, and also the gyro sensor 220 The position change value is applied.

When water is detected for a predetermined time or longer or the position change value exceeds a set value, the controller 200 may determine that the wearer has fallen into the water or has fallen. 5 seconds or longer) or if a sudden change in position occurs, since this is an emergency situation in which the wearer falls into the water, the controller 200 immediately opens the expanding agent storage unit 230 to supply the expanding agent to the inside of the tube 130. will do

Accordingly, the tube 130 expands and swells to tightly cover the wearer's neck, while also forming buoyancy to support the neck and prevent the head from being submerged in water.

In addition, when the pressure detected by the pressure sensor 260 provided inside the tube 130 exceeds the set value, the controller 200 closes the expansion agent storage unit 230 so that the expansion agent no longer passes through the tube 130. This is to prevent the inflated tube 130 from pressing the wearer's neck with great force.

That is, since the circumference of the neck of each wearer is different, safety accidents such as suffocation may occur when the neck is compressed with the same expansion force. ) is attached to the neck so that enough pressure is formed inside the tube 130.

As a result, when the neck circumference is long, less expansion agent is injected into the tube 130 to prevent excessive expansion, and when the neck circumference is small, more expansion agent is injected so that the tube 130 adheres to the neck is to be able to support

Due to the expansion of the tube 130, the heating element 131, the electrodes 133 and 134, and the body temperature sensor 135 are brought into close contact with the wearer's neck.

At the same time, the controller 200 detects the body temperature of the wearer by the body temperature sensor 135. Since the change in body temperature does not immediately decrease in the initial stage of being submerged in water, the temperature at which hypothermia begins is 35 ° C. or higher, for example, 35.5 ° C. When the temperature is below ~36°C, power is supplied from the battery 140 to the heating element 131 to transfer heat to the wearer's neck.

This prevents the wearer's body temperature from lowering to the temperature of hypothermia in advance.

In addition, the controller 200 controls the driving unit 240 to open the dye container 150 to spray the dye with water. In this case, the wearer's position can be directly checked with the naked eye, and the dye contains a fluorescent material. Since it is blended, the wearer's location can be easily identified even at night.

On the other hand, even if the wearer's body temperature is about 35.5 to 36 ° C, sensitive people may develop hypothermia symptoms, resulting in a state of confusion.

At this time, it is preferable to apply a stimulus from the outside so as not to lose consciousness. To this end, the controller 200 generates a low frequency to the electrodes 133 and 134 by driving the low frequency generator 250 when the body temperature of the wearer reaches 35.5 to 36 ° C. supply to prevent the wearer from losing consciousness due to electrical stimulation.

In addition, the controller 200 adjusts the temperature generated from the heating element 131 according to the wearer's body temperature to enable long-term heat generation. As shown in FIG. 5, the wearer's body temperature detected by the body temperature sensor 135 is relatively When the temperature is high, the battery 140 is controlled to lower the amount of heat generated by the heating element 131, and when the body temperature is relatively low, the amount of heat generated by the heating element 131 is controlled to increase.

Having described specific parts of the present invention in detail above, it is clear to those skilled in the art that these specific descriptions are merely preferred embodiments, and the scope of the present invention is not limited thereby. something to do.
