本発明は、主として在宅用として用いることができる無
呼吸検査装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apnea testing device that can be used primarily for home use.
日中過剰睡眠、慢性不眠症、全身倦怠感、高血圧、心不
全など、様々な疾患における呼吸、循環不全の発症の要
因として、睡眠中の無呼吸がある。Apnea during sleep is a factor in the onset of respiratory and circulatory failure in various diseases such as excessive daytime sleep, chronic insomnia, general malaise, hypertension, and heart failure.
睡眠中に１０秒以上呼吸が止まると無呼吸と判断され、
これが１晩に３０回以上認められる場合は睡眠時無呼吸
症候群といわれている。Apnea is considered to occur when breathing stops for more than 10 seconds during sleep.
If this occurs more than 30 times a night, it is said to be a sleep apnea syndrome.
この睡眠時無呼吸には、■呼吸中枢機能が原因で生ずる
中枢型睡眠時無呼吸、■睡眠中に上気道が閉塞するため
に生ずる閉塞型睡眠時無呼吸、■中枢型無呼吸で始ま９
、閉塞型無呼吸に移行する混合型睡眠時無呼吸の三つの

、どうしても終夜睡眠ポリグラフによシ脳波、眼球運動
、筋電図、心電図、呼吸曲線、呼吸運動、いびき、呼気
ガス分析、経皮的酸素飽和度（３ｄ０２ ）などを記録
して睡眠時の状態を検査する必要がある。This sleep apnea includes: ■ Central sleep apnea caused by respiratory center function, ■ Obstructive sleep apnea caused by obstruction of the upper airway during sleep, and ■ Central sleep apnea.
There are three types of mixed sleep apnea that progress to obstructive sleep apnea. For this reason, in order to definitively diagnose these pathological conditions, daytime tests cannot accurately assess these conditions, and all-night polysomnography is required to assess brain waves, eye movements, electromyograms, electrocardiograms, respiratory curves, and respiratory movements. It is necessary to record snoring, exhaled gas analysis, transcutaneous oxygen saturation (3d02), etc. to examine the patient's sleeping state.
しかしながら、終夜睡眠ポリグラフは、多数の検査を同
時に行うために、検査費用が高額であることや、検査の
ために入院しなければならないこと及び病院の設備数が
限られていることなどの理由から、睡眠時無呼吸症候群
の疑いのある患者全てにこの検査を行うことは実際的で
ないという問題がある。However, overnight polysomnography is expensive due to the large number of tests performed at the same time, requires hospitalization for testing, and has limited hospital equipment. However, there is a problem in that it is impractical to perform this test on all patients suspected of having sleep apnea syndrome.

ても経済的である。The home apnea testing device of the present invention includes an apnea measuring device having a function of detecting breathing and storing at least information regarding the breathing rate, breathing stop time, and breathing stop time as described above, and a device for processing data. Since the data processing computer and the data processing computer are configured separately, the apnea measurement device that performs the measurement function can be made smaller in size, and the patient can easily take the measurement home. In addition, after measurement, specific data such as breathing rate, breathing stop time, and breathing stop time can be easily obtained by connecting the apnea measurement device to a data processing computer installed at the hospital directly with a cable or through a telephone line. Therefore, a large number of apnea measurement devices can be used by installing one data processing computer. Furthermore, since it is possible to know at least the breathing rate, breathing stop time, and breathing stop time, it is easy to determine whether or not you have sleep apnea syndrome, and only if a more detailed diagnosis is required, overnight polysomnography should be used. It is only necessary to perform the test, and it is economical for the patient.

Figure 1 is a block diagram, 1 is the detection part and thermistor 2
, a microphone 3 and an electrode 4 are provided. No.:zm
As shown in , the thermistor 2 is attached to the nose of the subject 5 to detect temperature changes in the breathing air, and the microphone 3 is attached to the neck or upper chest of the subject 5 to detect temperature changes in the respiratory tract as the subject 5 breathes. The generated sound is detected, and the electrode 4 is attached to the chest of the subject 5 to detect the heartbeat. When breathing, airflow occurs in the airways and some sound is generated, so breathing can be detected using the microphone 3, but since it may be affected by other noises such as external noise, a thermistor 2 can be installed as a supplementary measure. be. This thermistor 2 detects breathing even though most of the breathing during sleep is normally done through the nose.
Depending on the situation, you may only need to breathe through your mouth, so it is not always safe to do it alone.
また、電極４は、必ずしも必要ではないが、呼吸が停止

する。6 is a signal processing unit that converts analog signals from the thermistor 2, microphone 3, and electrode 4 into digital signals, and converts the signals from the thermistor 2 and microphone 3 into at least the respiration rate, the respiration stop time, and the respiration stop time, respectively. Convert to information about. Regarding the respiration rate, for example, the number of respirations equivalent to - times per minute is calculated, and the state of each respiration is expressed by this value. In addition, the breathing stop time and the breathing stop time are, for example, when the breathing signals from the thermistor 2 and the microphone 3 are stopped for 10 seconds or more, the time when the signals stop and the time when the signals stop, respectively. .
電極４からの信号については、例えば１回の心拍が１分

Although the signal processing unit 6 of the present invention has a function of converting into a signal related to breathing stop time, breathing stop time, or heart rate, the signal processing unit 6 of the present invention is not necessarily limited to this, and the analog signal from the detection unit 1 is converted into a signal related to noise. The noise is removed by a filter, the signal is amplified appropriately by an amplifier, and the memory section 7
It is also possible to store the information in . In addition, the memory section T is
The present invention is not necessarily limited to storing digital signals as in the above embodiments, but may instead be a method of storing analog signals from the signal processing section 6 as they are.
以上の構成によると、無呼吸測定装置８によって呼吸数
