Collar life preserver for water sports

1. Collar life preserver for water sports that include a compressed inflatable life preserver ( 1 ), a cartridge ( 2 ) that is filled with CO2, a solenoid valve ( 3 ) in connection with the cartridge ( 2 ), a discharge valve ( 4 ), a sensor ( 5 ) associated with a microprocessor ( 6 ) programmed with an algorithm and emission/reception means between the valve ( 3 ) and the microprocessor ( 6 ), where the cartridge ( 2 ) can be recharged after each use, the sensor ( 5 ) associated with the microprocessor ( 6 ) is programmed with an algorithm that constantly receives information of the user's body functions and by means of predetermined values knows when the user is unconscious, the microprocessor ( 6 ) sends a signal to the solenoid valve ( 3 ) of the CO2 cartridge ( 2 ) for its automatic filling and there is a cord to manually activate the CO2 cartridge; wherein the sensor ( 5 ) includes

a pulse oximeter that detects a low level of oxygen saturation in the blood,

a cardiac sensor that detects an altered heart rate,

a movement sensor and a sensor that captures muscle contractions.

2. The collar life preserver according to claim 1 , in which the sensor ( 5 ) includes a depth sensor.

3. The collar life preserver according to claim 1 where the sensor ( 5 ) includes a sensor capable of sending external radio signals capable of being captured by life guards or emergency services.

4. The collar life preserver according to claim 1 where the CO2 cartridge can be replaced by any other means of gas generation, for example decompression of a solid by heat.
