When the snoring describes the operation of the device, the sleeper P sleeps in a state where the air pad 101 is placed on the back side as shown in FIG. 4A. The air pad 101 serves to detect breathing (vibration) of the sleeper. Since the air pad 101 is a known technique, a detailed description thereof will be omitted.

The breath detected by the air pad 101 is applied to the sensor 103 via the air tube 102.

The sensor 103 converts the applied breath detection signal into an electrical signal corresponding thereto, and outputs the preamplifier 104. Since the analog breath detection signal output from the sensor 103 is very weak, the signal of the rear stage is detected. In order to provide ease of processing, amplification is performed to a predetermined level in advance.

The amplified respiratory detection signal is applied to the central processing unit 105 as it is, and transmitted for detecting body movements (sleepers' movements), and is also applied to the band filter unit 110.

The band filter unit 110 filters the detection signal for each band by using the heart rate filter 111, the breathing filter 112, and the snoring filter 113 and applies them to the central processing unit 105, respectively. 2 shows an analog signal waveform for heart rate output through the heart rate filter 111, and FIG. 3 shows an analog signal waveform for breath output through the breathing filter 112. Referring to FIG. Each filter filters the breath detection signal input to the band set by the experiment in advance.

The central processing unit 105, when a signal for detecting breathing is input, stores the corresponding information in the memory 108 and simultaneously transmits the information to the display 106 so that the information corresponding to the function selected by the user is displayed on the screen.

In addition, if the function selected by the user is a snoring function to reduce snoring by analyzing the output signal of the snoring filter 113 to determine whether or not snoring. That is, snoring determination is determined as snoring when the output occurs through the snoring filter 113. In other words, when there is no snoring, the output of the snoring filter 113 does not occur. In contrast, when the snoring occurs, the output of the snoring filter 113 is generated, so that the central processing unit 105 It is easy to determine whether snoring.

If it is determined that the snoring is the central processing unit 105 generates a control signal for driving the pump to the drive unit 120, the motor driver 122 in the drive unit 120 for driving the motor in response to the control signal A driving signal is generated and applied to the motor 131. As a result, the motor 131 is driven to drive the pump for generating air. Here, the control signal for driving the pump is generated only for a predetermined time and automatically turned off.

When the pump is driven, air is generated, and the generated air is introduced into the air pad 101 through the air tube 102 to inflate the air pad 101. When the air pad 101 is inflated to some extent, the sleeper P cannot maintain the same sleeping posture as the first time and moves the body as shown in FIG. 4B, and the expansion of the air pad 101 is completed after a little time. In the state, as shown in FIG. 4C, the side is naturally turned sideways. If you turn it sideways, you will naturally have no snoring. If you sleep on your side, snoring does not occur because the narrowed throat can be extended again.

When the snoring is stopped by the operation as described above, the output of the snoring filter 113 does not occur, and accordingly, the central processing unit 105 determines that the snoring is stopped and generates an exhaust control signal. To the driving unit 120.

The solenoid driver 123 in the driving unit 120 generates a driving signal for driving the solenoid in response to the exhaust control signal applied thereto, and applies the driving signal to the exhaust solenoid 132. The exhaust solenoid 132 receives the driving signal. Open the solenoid valve to discharge the air injected into the air pad (101). Here, the solenoid control signal is also generated only for a preset time, and automatically turns off when the set time is reached.

When the air injected into the air pad 101 is discharged, the air pad 101 is restored flat as in the initial state.

After that, depending on whether the snoring is detected, the operation as described above is repeatedly performed.

On the other hand, when the apnea measurement function is set, the central processing unit 105 analyzes the output signal of the breathing filter 112 to determine whether or not apnea in real time. If it is determined that the apnea is a result of the determination, the corresponding information is stored in the memory 108 and the apnea state is displayed on the display 106 so that others can know it.

In addition, although not disclosed in the present invention, if only a separate alarm device is connected to the central processing unit 105, if it is determined that the apnea generates an alarm, so that others recognize that the sleeping person is apnea state. This is important for protecting sleepers from danger.

In addition, the present invention inputs a signal for changing the control program operated by the snoring to the central processing unit 133 through the debug switch 133, and to change the control program through the communication interface 134 By changing the control program in such a way as to store the control program in the memory 108 by inputting, it is easy to change the control program, thereby facilitating the function upgrade.

According to the present invention as described above, when detecting the snoring through the breath it has an excellent effect to reduce the snoring by inducing the air to automatically correct the sleeping posture by injecting air to the pad located on the back of the sleeper.

In addition, since it is possible to measure apnea in real time, there is an effect that can be prevented in advance, such as loss of time due to apnea measurement, waste of hospitalization.
