Abstract

The sounds of the beating heart are picked up by a microphone (1), amplified (2) and low-pass filtered (3) for processing by the microcontroller (5) which stores a digitised version in random-access memory (4). The frequency of the cardiac sound is measured during the recording. Prerecorded digitised sounds can be called-up from read-only memory (6) and converted to analogue form for reproduction by an amplifier (11) and loudspeaker (12). Duration and awakening time and phase can be programmed with a keyboard (10) and display (9). USE/ADVANTAGE - To improve sleep patterns of infants. Frequency of reproduction can be tuned manually or derived directly from that of the mother's heartbeat.

Description

Es wird ein Gerät beschrieben, welches zur Aufnahme, Speicherung und Wiedergabe von Herztönen dient, wobei die Aufnahme der Herztöne breitbandig erfolgt, d. h. vom menschlichen Ohr wahrnehmbare als auch tiefe, nicht wahrnehmbare Frequenzanteile werden gespeichert.A device is described which is used for recording, storage and playback of heart tones, the heart tones being recorded broadband, d. H. from human ear perceivable as well as deep, imperceptible frequency components are saved.

Es ist medizinisch erwiesen, daß mütterliche Herztöne auf Säuglinge beruhigend wirken und sie so besser einschlafen und durchschlafen, wobei nicht nur die vom Gehör wahrnehmbaren Frequenzen diese Wirkung erzielen, sondern auch die nicht hörbaren, tiefen Frequenzen, welche Säuglinge mit dem Körper fühlen. Der gleiche Erfolg kann bei Kindern oder Erwachsenen erzielt werden, die schlecht einschlafen oder unter Schlafstörungen leiden, wenn solche Herztöne über ein entsprechendes Wiedergabesystem im Kopfkissen des Betreffenden abgespielt werden.It has been medically proven that maternal heart sounds are soothing to infants work and so they fall asleep and sleep through better, not only that of Hearing perceivable frequencies achieve this effect, but not that audible, low frequencies that infants feel with the body. The same Success can be achieved in children or adults who fall asleep poorly or suffer from sleep disorders if such heart sounds have an appropriate Playback system can be played in the person's pillow.

Beim derzeitigen Stand der Mikrocontroller-Integration ist es kein Problem, ein oder mehrere Herztöne mit Hilfe eines Herzschallmikrofons aufzunehmen, zu digitalisieren und in einem Speicherbaustein zu speichern. Um auch sehr tiefe Frequenzanteile des Herzschalls aufzunehmen, ist es erforderlich den Aufnahmeteil mit Mikrofon und Verstärker entsprechend breitbandig auszuführen, und der Mikrocontroller muß zusammen mit dem Analog-/Digital-Wandler in der Lage sein, die Vielzahl an digitaler Information schnell genug zu verarbeiten. Das Wiedergabesystem ist entsprechend der Aufnahme ebenfalls breitbandig, um auch die tiefen, vom Körper eher fühl- als hörbaren Frequenzen abzugeben. With the current state of microcontroller integration, it is not a problem, either record, digitize several heart sounds with the help of a heart sound microphone and save it in a memory chip. To even very low frequency components of the To record heart sounds, it is necessary to record the microphone and Run amplifier accordingly broadband, and the microcontroller must together with the analog / digital converter to be able to handle the multitude of digital Process information quickly enough. The playback system is corresponding the recording also broadband, in order to also feel the deep ones deliver audible frequencies.  

Mit diesem Gerät ist es einerseits insbesondere für Säugliche möglich, einen oder mehrere Herztöne der Mutter aufzuzeichnen, zu speichern und über das im Kissen, auf dem der Säugling liegt, eingebauten Wiedergabesystem abzuspielen. Dadurch wird erreicht, daß der Säugling die vermeintlichen Herztöne der Mutter hört und fühlt und so besser einschläft und durchschläft. Die Wiedergabefrequenz kann dabei direkt aus der Frequenz der Herztöne der Mutter bestimmt oder manuell eingestellt werden. Ebenso kann die Dauer der Wiedergabe eingestellt werden, falls das Gerät nur zum Einschlafen benötigt wird.With this device it is possible on the one hand, especially for mammals, one or record several heart sounds of the mother, save them and use the pillow, on which the infant lies to play the built-in playback system. Thereby it is achieved that the baby hears and feels the supposed heart sounds of the mother and so falls asleep and sleeps through better. The playback frequency can be direct determined from the frequency of the mother's heartbeat or set manually. The duration of the playback can also be set if the device is only used for Falling asleep is needed.

Außerdem ist es möglich, mit diesem Gerät eine bestimmte Schlafdauer zu program­ mieren und zwar in der Form, daß nach Ablauf einer bestimmten Zeit, in der beruhi­ gende Herztöne wiedergegeben werden, sich die Frequenz der Herztöne allmählich erhöht, bis zu einer Frequenz, bei der sie nicht mehr beruhigend wirkt und der Mensch dann langsam daran aufwacht. Damit kann z. B. eine Schlafphase für einen Mittagschlaf programmiert werden mit beispielsweise einer Stunde Schlaf und 10 Minuten Aufwachphase. Statt der Dauer für eine Schlafphase kann auch direkt eine Weckzeit programmiert bei deren Erreichen ebenfalls die Aufwachphase mit höher werdender Frequenz beginnt.It is also possible to program a certain amount of sleep with this device mieren in the form that after a certain time, in the calm heart tones are reproduced, the frequency of the heart tones gradually increased to a frequency at which it no longer has a calming effect and which Then people wake up slowly. So z. B. a sleep phase for one Noon sleep can be programmed with one hour of sleep and 10 Minutes of waking up. Instead of the duration of a sleep phase, one can also directly When the alarm time is reached, the wake-up phase is also programmed with a higher one frequency begins.

Schlafstörungen werden heutzutage meistens mit Medikamenten behandelt, die unter Umständen sogar denjenigen, der sie längere Zeit einnimmt, davon abhängig ma­ chen. Das Gerät dient dazu, Menschen mit Schlafstörungen, wie etwa schlechtes Ein­ schlafen oder mehrmaliges Aufwachen in der Nacht, zum Durchschlafen und so zu einem für den menschlichen Körper gesunden Schlaf zu verhelfen ohne die Einnahme von Medikamenten und daher auch ohne Gefahr der Abhängigkeit bei Einnahme stärkerer Schlafmittel.Nowadays, sleep disorders are mostly treated with medication that is under Under certain circumstances, even those who take it for a long time, depending on it chen. The device is used to help people with sleep disorders, such as poor on sleep or wake up several times at night to sleep through and so on to help a healthy sleep for the human body without ingestion of medication and therefore without risk of dependence when ingested stronger sleeping pills.
