Abstract

The diagnostic device to indicate a heart attack which is not immediately apparent without non transportable laboratory apparatus is a compact electronic unit which can be attached by a strap onto the thorax or hung around the neck. It employs an electrode which is attached adhesively to the thorax and by means of an electromagnet or coil, obtains signals corresponding to the heart action. These are registered on a tape. By use of integrated circuits, the device is miniaturised and battery operated. The circuit includes an oscillator to modulate the generated signal, followed by demodulation.

Description

Herzanfall-Diagnostikgerät Heart attack diagnostic device

Es iibt eine ganze Reihe voii herzanfällen, wie die vershiedenen Formen von paroxysmalen Tachykardien, die Adams-Stockes'schen Anfällen und Anfällen von Vorhofflimmern und -flattern, die in der Praxis und auc in der Klink manchmal sehr schwer zu diarnostizieren sind, da sie anfallsweise auftreten, wenn kein E@G-Gerät zur Verfüngung steht, und das LKG außerhalb der Anfälle öfters ganz normal ist.There are a number of heart attacks, including various forms of paroxysmal tachycardias, the Adams-Stockes seizures and seizures of Atrial fibrillation and flutter, which in practice and also in the clinic sometimes very much Difficult to diagnose as they are seizure without an E @ G device is available, and the LKG is often quite normal outside of the seizures.

Zur Behebung dieses Mißstandes und zur genauen Diagnostik dieser Anfällt wurde deshalb dieses Gerät erfunden.To remedy this situation and to diagnose it precisely That is why this device was invented.

Durch Verwendung von IC's und Miniaturisierung der bausteine knn das Gerät in Kleinformat und flach hergestellt werden und wird den Patienten, die unklare Anfälle bekommen, mitgegeben. Das Gerät wird entweder mittels eines Hiemens oder eines Gurts vorne am Thorax befestigt, oder durch eine Schnur bzw. einen Gurt Halse gehängt. Die elektrischen phänomene ( Strom- und Potentialschwankungen), die während der @erzaktionen auftreten, werden mittels einer Klebe-Elektrode, die ander vorderen befestigt wird, aufgenommen und nach (tranzistor-) Verstärkung durch einen Elektromagnet in Mahnetfeldschwankungen umgesetzt und auf einer kleinen Magnetband aufgezeichnet. Die Stromversorgung des Gerätes unfolgt durch Batterie bzw. Akku.This can be achieved by using ICs and miniaturizing the components Device can be manufactured in small format and flat and will be unclear to the patient Get seizures, given. The device is either by means of a hiemen or a belt attached to the front of the thorax, or by a cord or a belt neck hanged. The electrical phenomena (current and potential fluctuations) that occur during the @erzaktion occur, are by means of an adhesive electrode, the other front attached is recorded and after (tranzistor-) amplification by an electromagnet in Mahnet field fluctuations implemented and recorded on a small magnetic tape. The power supply of the device is not followed by battery or accumulator.

Bei Auftreten von Anfällen bzw. deren Vorboten schalten der Patient bzw. seine Angehörige das Gerät durch Knopfdruck ein und der Anfall wird, wie oben beschrieben, auf dem Band registriert. Das Gerät schaltet sich nach der nde des kurzen Bandes automatisch ab. Das Band wird dann herausgenommen und an eine Zentrale eingeschickt. Jn der Zentrale werden durch ein geeignetes Gerät die auf den Land gespeicherte magnetischen Informationen nach kräftiger Verstärkung in mechanische Bewegungen umfewandelt ( z.b. durch Elektromagneten bzw. pulen) und die EKG-Kurve registriert und an den Arzt bzw. Patienten zurückgeschickt. Auf diese Weise können auch sehr kurze unklare Berzanfälle diagnostiziert werden. Zur Verbesserung der beschriebenen Technik und zwecks besserer Verstärkung können evt.In the event of seizures or their harbingers, the patient switches or his relatives turn the device on by pressing a button and the seizure will be as above described, registered on the tape. The device switches itself off after the end of the short tape automatically. The tape is then taken out and sent to a central office sent in. In the headquarters, a suitable device is used to monitor the land stored magnetic information after strong amplification in mechanical Movements converted (e.g. by electromagnets or pulsing) and the ECG curve registered and sent back to the doctor or patient. That way you can very brief unexplained seizures can also be diagnosed. To improve the described technique and for the purpose of better reinforcement can possibly.

auch die potentialschwankungen, die während der Herzaktionen auftreten mit einer Oszillator-Frequenz moduliert und später in der Zentrale wieder demoduliert werden.also the potential fluctuations that occur during cardiac actions modulated with an oscillator frequency and later demodulated again in the control center will.
