Abstract

The arrangement for determining pulse signals results selectively using a stereo method. The pulse signals are selectively stored in a data storage. The optical and/or acoustic reproduction of the data results selectively, independent of time.

Description

In der Medizin wird eine hohe Genauigkeit bei der Erfassung von Pulsen gefordert.In medicine, there is high accuracy in the detection demanded by pulses.

Anwendungsformen zur Ermittlung sind allgemein bekannt als pneumatische- und elektronische Aufnahmeeinrichtungen.Application forms for the determination are generally known as pneumatic and electronic recording devices.

In der Fachliteratur sind Anordnungen zu finden; so z. B. eine Vielgestaltigkeit der Stethoskope. ("Praxis Partner"; Frühjahr 96, Fachversand für Arzt- und Laborbedarf S. 137 bis 144).Arrangements can be found in the specialist literature; so z. B. a variety of stethoscopes. ("Practice Partner"; Spring 96, mail order for doctor and laboratory supplies Pp. 137 to 144).

Diese technischen Konstruktionen haben die Nachteile, daß eine räumliche Erfassung und/oder eine Speicherung der Pulssignale nicht erfolgt.These technical designs have the disadvantages that a spatial registration and / or storage of the Pulse signals did not occur.

Ziel der Erfindung ist es, eine Stereoabnahme der Signale mit hoher Genauigkeit zu gewährleisten, eine Speicherung vorzu­ nehmen und eine zeitunabhängige Wiedergabe in optischer- und/oder akustischer Darstellung bei einer hohen Verstär­ kung zu realisieren.The aim of the invention is to use a stereo decrease of the signals to ensure high accuracy, storage prior take and a time-independent reproduction in optical and / or acoustic display at a high ampl realization.

Durch das Stereoabtastsystem können Krankheiten, wie z. B. Herzklappenfehler, Herzrhythmusstörungen etc. schneller und differenzierter beurteilt werden.The stereo scanning system can diseases such. B. Heart valve defects, cardiac arrhythmia etc. faster and be judged more differentiated.

Die Anordnung zur Aufnahme der Pulssignale hat ein kleines Volumen und ist sehr kostengünstig.The arrangement for recording the pulse signals has a small one Volume and is very inexpensive.

Der Erfindung liegt die Aufgabe zu Grunde, eine Anordnung zur Ermittlung von Pulssignalen im medizinischen Bereich mit hoher Genauigkeit und Speichervermögen zu entwickeln.The object of the invention is an arrangement to determine pulse signals in the medical field with to develop high accuracy and storage capacity.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß ein Stereoabnehmer benutzt wird.According to the invention the object is achieved in that a Stereo pickup is used.

Als Ausführungsformen sind Kondensatormikrofone, aber auch Systeme auf piezoelektrischen Prinzip arbeitend, möglich.As embodiments, condenser microphones are, however, also Systems based on the piezoelectric principle possible.

Die Anordnung ist wahlweise in Stereo- oder Monobetrieb umschaltbar.The arrangement is either in stereo or mono mode switchable.

Die Tonabnehmereinrichtung ist konstruktiv so gestaltet daß der Abstand beider Tonabnehmerteile geändert werden kann, um die Stereobedingungen zu optimieren.The pickup device is designed constructively that the distance between the two pickup parts are changed can to optimize the stereo conditions.

Anordnung Pulssignal-Aufnahme (Fig. 1), ist auch zur Wiedergabe umschaltbar. Arrangement pulse signal recording ( Fig. 1), is also switchable for playback.

Die Pulssignale können wahlweise gespeichert werden und sind wahlweise zeitunabhängig abrufbar.The pulse signals can be optionally stored and are optionally available at any time.

Als Verstärkereinrichtungen dienen elektronische Baugruppen.Electronic assemblies serve as amplifier devices.

Die Anordnung ermöglicht durch die Eingabe des Speichers (z. B. Kassette), die Signale optisch und/oder akustisch wiederzugeben.The arrangement enables by entering the memory (e.g. cassette), the signals optically and / or acoustically to play.

Zur sicheren Speicherung und besseren Darstellung sind ggf. Frequenzumsetzer (Wandler) erforderlich.For safe storage and better presentation, Frequency converter (converter) required.

Mittlere Frequenzbereiche lassen sich vorteilhaft speichern.Medium frequency ranges can be stored advantageously.

Optoelektronische Koppler verhindern Resonanzneigungen.Optoelectronic couplers prevent resonance tendencies.

Steckverbinder ermöglichen eine wahlweise Zusammenschaltung der einzelnen Baugruppen.Connectors enable an optional interconnection of the individual assemblies.

Als akustische Wiedergabeeinrichtungen sind Ohrhörer sinnvoll, aber auch Kopfhörer möglich, Lautsprecher vorzugsweise nach Fig. 2. Ohrhörer stellen einen unmittelbaren Kontakt zum Gehörgang dar. Dadurch erfolgt eine weitere Verstärkung und äußerliche Störgeräusche werden ausgeschalten.Earphones are useful as acoustic reproduction devices, but headphones are also possible, loudspeakers preferably according to FIG. 2. Earphones represent direct contact with the ear canal. This results in further amplification and external interference noises are switched off.

Anwendungsgebiete der Erfindung sind ambulante- oder stationäre medizinische Einrichtungen.Fields of application of the invention are outpatient or inpatient medical facilities.
