JP3198239U - Device that encourages sleep posture change when detecting apnea during sleep - Google Patents

Abstract

An apparatus for prompting a sleep posture to be changed upon detection of apnea is provided. Respiration is stopped based on a nasal cannula or nasal cannula for a respiratory detection sensor, a condenser microphone for converting a breath change input to the nasal cannula or nasal cannula into an electrical signal, and the electrical signal. The sound device 10 or the mechanical device that promptly notifies the sleeper by sound or mechanical vibration and prompts the sleep posture to be changed when it is determined that the pre-set apnea time has been reached And a vibration device 11. Moreover, the terminal 12 which can output the DC signal during an apnea is provided. By connecting a data recorder to this terminal, the time of occurrence of apnea, duration of apnea, etc. can be recorded from the internal time, and can be analyzed by itself. [Selection] Figure 1

Description

The present invention relates to a device for prompting a change in sleep posture when apnea is detected during sleep.

When you lie on your back during sleep, the base of the tongue tends to fall into the upper respiratory tract, so snoring and apnea are likely to occur. The occurrence of snoring and apnea are closely related. However, when snoring occurs, there is a device that picks up the snoring sound with a microphone and generates an alarm by sound or vibration, etc., to prompt the change of posture during sleep, but when apnea occurs, change of posture during sleep I don't see any device that prompts.

With conventional devices, when snoring occurred during sleep, snoring was detected and an alarm was generated to prompt the user to change his / her posture during sleep (such as from side to side). Since no sound was produced, it could not be detected and an alarm could not be issued. The present invention is designed to generate an alarm when the apnea continues for a certain period of time or more, thereby prompting a change of posture during sleep.

In order to solve the above-mentioned problem, the nasal cannula or the nostril cannula for the respiratory detection sensor and the condenser microphone are used as sensors with a simple configuration as shown in FIG. Notification by dynamic vibration was made to encourage changing posture during sleep. In addition, when an external data recorder or the like is connected, the occurrence time, apnea time, etc. can be recorded and analyzed by itself.

In sleep, conventionally, the effect of prompting a change in sleep posture when snoring occurred could be expected, but since there was no function for the occurrence of apnea, it was not possible to promote the change of sleep posture due to apnea. The present invention can be expected to contribute to health promotion by prompting a change in sleep posture for the occurrence of apnea during sleep that does not require mild treatment and shortening the apnea time.

FIG. 1 is an explanatory view showing a method for carrying out the present invention. Example 1

Since this device can be easily used even when traveling, such as travel, it is a palm-sized lightweight and portable device, and is realized with a minimum number of parts so that it can be used at low cost.

FIG. 1 is a functional block diagram of an embodiment of the device of the present invention, wherein 1 is a nasal or nasal cannula for a respiratory detection sensor, 2 is a condenser microphone, 3 is a microphone amplifier, 4 is a low-pass filter, 5 is an amplifier, 6 is an amplitude comparator, 7 is a timer, 8 is an acoustic signal oscillator / driver, 9 is a vibration device driver, 10 is an external sound generator (speaker, earphone, etc.), 11 is a mechanical vibration device (vibration) Motor, etc.), 12 is a terminal for outputting an apnea signal during an apnea occurrence period, 13 is a power supply device, 14 and 15 are connection cables, and 16 is a main body case. .

As for the operation, in FIG. 1, exhalation is taken in by a nasal cannula or a nasal cannula for a single breath detection sensor, and a change in air pressure from the cannula is converted into an electric signal by two condenser microphones incorporated in a main body case of 16. Then, amplification is performed with three microphone amplifiers. Subsequently, only the exhalation signal is passed through the low pass filter 4 and the level of the signal filtered by the amplifier 5 can be judged by the amplitude comparator 6 and amplified to the level. The timer 7 is for determining apnea, but when breathing has not stopped, the timer is reset by the expiration signal. When breathing stops and the timer advances and times out, 8 acoustic signal oscillators / drivers or 9 mechanical vibration drivers are activated, and 10 acoustic devices (speakers, earphones, etc.) attached to the outside Or 11 mechanical vibration devices (vibration motor etc.) operate | move and alarm a sleeper. At the same time, a DC signal is output to the 12 output terminals. Reference numeral 13 denotes a power supply device that incorporates two AA or AAA batteries.

Claims (2)

During sleep, changes in expiration input to the nasal cannula or nasal cannula for a breath detection sensor are converted into an electrical signal by an inexpensive condenser microphone, and acoustic or mechanical vibration is reached when it is time to determine that apnea is set in advance Thus, it has an alarm function that notifies the sleeper temporarily and prompts the sleep posture to be changed. After the alarm is generated, the alarm is automatically reset when breathing recovery is achieved. A signal output terminal for outputting the apnea signal to the outside and recording it in a data recorder or the like is provided.
