Description of the state of the art

Sleep disorders are problems that are related to sleep. Among the different sleep disorders are sleep apnea, problems falling asleep and staying asleep, excessive sleep and any behavior that goes beyond normal sleep. Apnea is the interruption of periodic breathing for a period of time. In some individuals this suspension of breathing occurs during sleep, this is called sleep apnea and is considered a sleep disorder.

To treat apnea during sleep, the state of the art reports the use of masks that provide continuous positive pressure in the respiratory tract (Continuous Positive Airway Pressure, by its acronym in English CPAP) that with the use of a mask connected by means of a hose to An air supply system prevents the occurrence of sleep apnea. Other devices described in the state of the art propose a different approach for the treatment of sleep apnea or avoid snoring, as, for example, those disclosed in US 2006/0276701 Al and US 5,381,201.

US 2006/0276701 discloses a self-contained conditioning device for the treatment of sleep apnea and a method. The self-contained conditioning device disclosed in US 2006/0276701 comprises a mounting device with at least one respiratory sensor, at least one transducer; at least one critical signal electrode and a control unit connected to each sensor and each transducer; where the mounting device is in contact with the user's skin and at least one of the sensors senses the information indicative of the user's breathing and where in addition the control unit transmits an alarm to the user through one of the transducers of according to a variation in the user's respiratory cycle, also transmits a painful pulse by means of the critical signal electrode when the previous alarm has not been attended by the user. The autonomous conditioning method disclosed in US 2006/0276701 which consists of installing the assembly device, with at least one respiratory sensor; at least one transducer; at least one critical signal electrode; the sensor, the transducer and the electrode are electrically connected to a control unit; sensing the breathing cycle; conditioning the patient to maintain the desired breathing cycle using an actuator and negatively rewarding the patient if he fails to maintain the desired breathing cycle. The electrodes must be in contact with the skin having the skin to be prepared with oil to improve the contact of the electrodes which causes discomfort in the patient, in addition the construction material in some users can cause irritation or allergies. In the same way, if a cable is used to connect the electrodes, the user could disconnect them if they are not fixed properly. US 5,381,801 discloses an apparatus for the prevention of snoring comprising a strap with a plurality of pockets installed in its length, at least one vibrator installed in one of the side pockets and another installed in one of the back pockets; and a time switch and pressure switch. The effectiveness of the device depends on the number of switches it has, its effectiveness is very low, it also depends on the rigidity of the surface on which the user is lying, if the rest surface is very soft, it may not activate The pressure sensor, the device is very large to be used comfortably and cause other types of sleep disorders. It forces the user to remain in a certain position which is uncomfortable for the user and trigger other problems related to the user's postural hygiene.

Thus, the state of the art discloses devices for correction of sleep apnea, however, these are uncomfortable for the user, their mobility is questionable, they are subject to a specific position of the user that could trigger other problems even different to sleep disorders such as neck pain, back pain, muscle contractures, limited movement of the neck or back, numbness and tingling in the arms and legs, the appearance of herniated discs, osteoarthritis, among others.

20. The method of claim 17 wherein in step a sensitivity threshold reference acceleration ranging from -19.62 m / s ² to +19.62 m / s2 and set the sensitivity threshold reference magnetic ranging from - 1200 μΤ up to +1200 μΤ.

The method of claim 17 wherein in step b a user establishes a second reference sensitivity time interval and stores it in a memory register and in step c a user establishes a second time interval of transducer activation and storing it in a memory register, in step e, comparing the signal monitored in step d with the thresholds of stage a; if the result of the comparison exceeds the thresholds established in step a during the second sensitivity time interval of step b, then activate a transducer during the second activation time interval established in step c, return to step d, if no acceleration is recorded during a second activation interval, then activate the transducer again during the second activation time interval established in step c. wherein the second sensitivity range established by a user in step b is less than the first sensitivity range established by a user in step b.

22. The method of claim 17 wherein in step d the orientation of the axes of a sensor (7) and a second sensor (9) is recorded.

23. The method of claim 17 wherein in step b the first time interval of sensitivity ranges from 6 seconds to 12 seconds.

The method of claim 17 wherein in step c the first time interval of activation of the transducer ranges from 1 second to 5 seconds.
