Description

Die Erfindung betrifft ein Gerät zur oszillatorischen Blutdruckmessung, Pulsüberwachung und zur oszillographischen Aufzeichnung peripherer Durchblutungsstörungen mittels einer Druckmanschette, die mit einer Meßkammer in Verbindung steht, die durch eine Membran in zwei Räume derart unterteilt ist, daß die Membran beiderseits dem statischen Manschettendruck ausgesetzt ist und nur von den Druckänderungen ausgelenkt wird. The invention relates to a device for oscillatory blood pressure measurement, Pulse monitoring and for the oscillographic recording of peripheral circulatory disorders by means of a pressure cuff which is in communication with a measuring chamber, the is divided by a membrane into two spaces in such a way that the membrane on both sides is exposed to the static cuff pressure and is only deflected by the pressure changes will.

Bei einer bekannten Vorrichtung dieser Art wird die Bewegung der Membran dadurch gemessen, daß diese als Belag eines Kondensators ausgebildet ist und die bei der Bewegung der Membran auftretenden Änderungen der Kapazität dieses Kondensators in eine elektrische Meßgröße übergeführt werden. In a known device of this type, the movement of the Membrane measured in that it is designed as a coating of a capacitor and the changes in the capacitance of the membrane that occur when the membrane is moved Capacitor can be converted into an electrical measured variable.

Die Erfindung bezweckt, die Membranbewegungen mittels eines piezoelektrischen Kristalls zu messen, anzuzeigen und aufzuzeichnen. Erfindungsgemäß ist daher ein piezoelektrischer Kristall vorgesehen, auf den sich die Membranbewegungen übertragen und dessen abgegebene Spannung gemessen wird. The aim of the invention is to control the diaphragm movements by means of a piezoelectric Measure, display and record crystal. According to the invention is therefore a piezoelectric crystal is provided to which the diaphragm movements are transmitted and its output voltage is measured.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Druckkammer h ist durch die Gummischläuche d und e mit der Gummiblase f der Manschette verbunden. b ist ein Ring, auf dem die bewegliche Membran c befestigt ist. An der Mitte der Membran ist ein Stift befestigt, der die Bewegungen der Membran auf den Biegekristall k überträgt. Der Biegekristall k ist durch eine Haltevorrichtung I befestigt. Der eine metallische Belag des Biegekristalls k ist über die Haltevorrichtung 1 mit Masse verbunden, während der zweite Belag des Biegekristalls über die isolierte Durchführung g nach außen geführt wird. An exemplary embodiment of the invention is shown in the drawing. The pressure chamber h is through the rubber hoses d and e with the rubber bladder f the Cuff connected. b is a ring on which the movable diaphragm c is fixed is. A pin is attached to the middle of the membrane, which controls the movements of the membrane transfers to the bending crystal k. The bending crystal k is by a holding device I attached. One metallic coating of the bending crystal k is over the holding device 1 connected to ground, while the second layer of the bending crystal is isolated via the Implementation g is led to the outside.

Durch die Bewegungen der Membran c, hervorgerufen durch die Pulsationen der Arterie über die Gummiblase t und die Gummischläuche d und e, werden durch den Stift i diese Bewegungen auf den Biegekristall k übertragen, wodurch Ladungen auf dem Biegekristall erzeugt werden, welche in üblicher Weise verstärkt und zu einem Oszillographen oder Braunschem Rohr geführt werden. By the movements of the membrane c, caused by the pulsations of the artery via the rubber bladder t and the rubber tubes d and e, are passed through the Pen i transferred these movements to the bending crystal k, creating charges on it the bending crystal are generated, which reinforced in the usual way and become one Oscillographs or Braunschem Rohr can be performed.

Die Verwendung eines Biegekristalls hat gegenüber der Verwendung eines veränderlichen Kondensators nachstehende Vorteile: I. Der erzielte elektrische Effekt ist beim Biegekristall größer als beim veränderlichen Kondensator. The use of a bending crystal has over against the use of a variable capacitor has the following advantages: I. The obtained electrical The effect is greater with the bending crystal than with the variable capacitor.

2. Die Nullpunkteinstellung beim Biegekristall ist weniger schwierig als beim veränderlichen Kondensator.2. The zero point adjustment with the bending crystal is less difficult than with the variable capacitor.

3. Die von der Druckdose abgegebenen Spannungen des Biegekristalls können ohne jegliche Schaltumänderungen sofort an den Verstärker eines Elektrokardiographen angelegt werden.3. The tension of the bending crystal given off by the pressure cell can immediately be connected to the amplifier of an electrocardiograph without any switching changes be created.

Die bei den meisten Kliniken und Arten vorhandenen Elektrokardiographen können durch die zusätzliche Verwendung der Druckdose mit Membran und Biegekristall zur Blutdruckmessung und Pulsüberwachung benutzt werden. Außerdem hat es den Vorteil, daß das Bedienungspersonal bereits mit der Handhabung des Elektrokardiographen vertraut ist. The electrocardiographs found in most clinics and types can be achieved through the additional use of the pressure cell with membrane and flexible crystal can be used for blood pressure measurement and pulse monitoring. It also has the advantage of that the operator is already familiar with the handling of the electrocardiograph is.

Wie weitere Untersuchungen mit diesem Gerät an Patienten gezeigt haben, kann dieses Gerät, besonders wenn eine oszillographische Aufzeichnung wie beim Elektrokardiographen angewandt wird, zur Beurteilung peripherer Durchblutungsstörungen an Extremitäten mit gutem Erfolg angewandt werden. As further studies with this device on patients have shown this device, especially if you like an oscillographic recording is used in the electrocardiograph to assess peripheral circulatory disorders be used on extremities with good success.
