    SECURITY DEVICE FOR THE PRACTICE OF SPORTS IN APNEA
    5 SECTOR OF THE TECHNIQUE
    The present invention is located in the area of mechanical engineering.
    10 STATE OF THE TECHNIQUE
    The sport of diving in apnea involves real risks and generates a considerable number of accidents. In general, accidents are related to loss of consciousness. The loss of knowledge is suddenly and the diver does not realize the danger.
    There are no known devices that guarantee safety in the underwater environment.
    20 Among the protection elements known in the
    In the marine environment there are life jackets that can be inflated by blowing through a small tube or pulling a rope that activates a CO2 cartridge. This type of vests allows the subject's head to remain out of the water, even in a state of unconsciousness.
    There are evolutions of this type of vests that allow them to automatically inflate upon contact with water.
    The first floating system specially designed for divers was an inflatable collar, without an inner bladder, introduced in 1961 by the French company Fenzy. It was constructed of cloth, and the joints were sealed with glue. Another distinctive feature was the fact that it carried a bottle of compressed air 35 that was filled with the bottle. The air passed from the bottle
    to the collar, through a small valve, with which the collar was inflated and converted, by the way, into a small reserve of extra air. To release the air content inside the collar, diver 5 used the manual inflation / deflation nozzle.
    Subsequently, the same company introduced a redesigned model that became the first true hydrostatic vest, using a low pressure hose that connected to the lower chamber of the regulator 10 and with a button that regulated the passage of air.
    Said device is equipped with two internal bladders, one served as an air reserve and inflated manually, while the other provided buoyancy control to the diver.
    15 The current new designs are based on this
    described development Basically they distribute the air to the back and sides, which allows to offer adjustable straps with easy-release plastic buckles, which are the most common used in air navigation and 20 maritime. This air distribution to the part
    later makes the models much more compact and smaller.
    However, there are no known devices that divide the bladder into different air chambers with inflation
    25 sequential In our case there is a development that
    It consists of dividing the bladder into different air chambers, in order to better control the distribution of air within the vest. This prevents air from accumulating all on one side, which at shallow depth and with 0 inexperienced divers causes uncontrolled rises to
    surface, with the danger you are carrying (baro pulmonary trauma and other factors).

    BRIEF DESCRIPTION OF THE INVENTION
    A safety device (Figure 1) is proposed for the practice of sports in apnea based on a life jacket but re-adjusting the bladder in three 5-air chambers so that the opening and inflation is performed in three stages.
    It is formed by different air chambers strategically placed in such a way that it allows the subject to be rotated conveniently and safely ejected to the surface.
    This is achieved by giving a curvature to the different chambers, managing to distribute the pressure forces exerted in the inflation by the perimeter, making a controlled inflation by parts, until reaching the complete inflation 15 of the vest. With this solution it is achieved that with two pieces cut to the stipulated and heat-sealed measures, form a single bladder with three chambers.
    The shape and location of the curvature facilitates a controlled ascent, so that once the subject is ascending to the surface, pressure is made on the neck and the airways are opened.

    DETAILED DESCRIPTION OF THE INVENTION
    It is a device based on a life jacket with the particularity that the inflation is carried out in three stages. The inflating stages are conditioned by the position and curvature of the different air chambers (Figure 2):
    First stage: Inflating the bladder on the left side first. This inflation is done so that the individual is in the position that this performs a primary turn in side position and a partial secondary in vertical position, always looking for the head is above the lower limbs.
    Second stage: once the first chamber is inflated, the gas passes to the second chamber, which surrounds the place of the cervical and neck area, with the function of continuing to turn the individual, placing it in an almost vertical position and performing the thrust from it to the surface.
    Third stage: once the ascent to the surface has begun and the second chamber in the bladder is filled, the third chamber begins to fill which stabilizes the individual in an upright position ascending to the surface. This third camera is located on the side of the right side.
    Finally, the last part of the ascent positions the individual vertically while the inflation of the three chambers continues and ends, increasing the pressure on his

    inside, so that when the maximum pressure of the assembly is reached, an inclination movement is exerted on the individual's neck backwards (similar to that of the CPR maneuver), allowing the affected person to have a slightly inclined head pressing on the lower jaw facilitating opening of the respiratory vlas and also facilitating the first breath of air.
    This whole process is done so that the injured, regardless of the initial position, is placed vertically and does not ascend face down or on their backs, etc.
    EXAMPLE OF REAL I ZAC I ON OF THE INVENTION
    A device with the curvatures proportionally similar to those shown in Figure 3 is selected. The device can be formed with nylon-polyurethane with heat seal.
    The necessary components are added, so that the system is activated once sports practice is started and in this way the constants and the environment surrounding the individual are continuously monitored, verified and checked.
    Once a dangerous variation is detected in the analysis of the data obtained from the sensors, located, for example, as shown in Figure 3, the bladder inflation is activated. This activation is done if:
    The pulse oximeter sensor detects a low level of oxygen saturation (02) in blood.
    The cardio sensor detects an unusual and out of range stop or heart rate.
    The diaphragmatic sensor detects a distortion of
    crossing.
    The depth sensor detects the maximum depth established or if the ascent to the surface of the apnea does not occur, descending again.
    5 Once the activation signal is sent, the valve is opened, drilling a cylinder of a gas (C02 / in our case) by discharging it and filling the bladder of the device with said gas.
    10 In this way, the subject always ascends to the surface vertically, getting the head to tilt slightly gradually (Figure 2) so that water does not enter the respiratory tract and once the surface is reached it has already tilted backwards the head (as the 15 practice "of mouth to mouth in the ground") leaving him free the airways for the entrance and exit of the air in the lungs.
    Once the athlete is on the surface, a module of 20 GPS can locate your location, and in turn a GPS module and radio beacon, you can send the distress signals and the medical parameters, mobilizing the medical and rescue teams.
    With this design, an inflation time of the three three stages of less than 3 seconds is achieved, which means that in less than 60 seconds (time calculated in a test conducted at a depth of 50m) the individual has his head out of the Water.
