Description
Elektrode für Elektrodiagnoscope Gegenstand der Erfindung ist eine Elektrode, welche vom Arzt an verschiedenen Körperstellen des zu Untersuchenden angelegt wird, während dieser mit einer Hand die andere Elektrode in leitende Verbindung mit seinem Körper bringt. Die bekannten Elektroden können mit verschieden starkem Druck auf die betreffende Stelle aufgelegt werden, wodurch sich die Stromstärken ändern und die Ergebnisse der Messungen unrichtig werden. Um einen derartigen Einfluß des Untersuchenden (Arzt) auf die Messung_ en auszuschalten, ist die Elektrode gemäß der Erfindung so eingerichtet, daß der Druck, mit dem das flüssigkeitsbindende Ende derselben auf der betreffenden Körperstelle aufliegt, an einem Zeiger abgelesen werden kann, so daß der Untersuchende (Arzt) in der Lage isst, den Druck jeweils nur so stark auszuüben, als er dem betreffenden Zeigerstand der Skala entsprechend ausgeübt werden soll, und beispielsweise an gleichen Stellen verschiedener Körper immer genau denselben Elektrodendruck auszuüben, so daß die Messungen ohne weiteres miteinander verglichen werden können.Electrode for Electrodiagnoscope The invention is a Electrode placed by the doctor on different parts of the body of the person to be examined is applied while this with one hand the other electrode in conductive connection brings with his body. The known electrodes can be of different strength Pressure can be applied to the affected area, which increases the current strength change and the results of the measurements become incorrect. To such an influence of the examiner (doctor) to switch off the measurements, the electrode is in accordance with of the invention set up so that the pressure with which the liquid-binding end the same rests on the body part concerned, read on a pointer can be so that the examiner (doctor) eats the pressure each time only exercise as much as it corresponds to the pointer position in question on the scale should be exercised, and for example in the same places on different bodies always exert exactly the same electrode pressure so that the measurements can be taken without further ado can be compared with each other.
Auf der Zeichnung ist eine beispielsweise Ausführungsform der neuen Elektrode in einem Axialschnitt und teilweiser Draufsicht dargestellt.In the drawing is an example embodiment of the new Electrode shown in an axial section and partial plan view.
Das auf die Körperstelle. aufzusetzende Ende i der Elektrode in. Formeines kugeligen Knopfes aus leicht Feuchtigkeit ansaugendem Stoff sitzt fest an dem zylindrischen Stiel e aus Stahl, der vorn in ,einer Messingbüchse 3 und hinten. in einer ebensolchen, 4, geführt ist, die in einem Handgriff 5 aus nicht leitendem Stoff, z. B. Hartgummi., stecken. Der Stiel z ist mit der Büchse 3 axial. im Handgriff verschieblich und von einer Spiralfeder 6 umgeben, die sich hinten gegen die Stirne der im Handgriff festen Büchse 4, vorn gegen die Stirne der Büchse 3 legt, mit welcher der Stiel durch einen radial eingesetzten Zeigerstift 7 verbunden ist. Dieser Zeigerstift gleitet bei axialer Verschiebung des Stieles 2 in einem Schlitz 8 des Handgriffs, zu dessen beiden Seiten eine -Teilung (s. Abb.2) angebracht ist, deren Nullpunkt an der vorderen Endstellung des Zeigerstiftes liegt. Wenn nun der Knopf i auf die zu untersuchende Körperstelle aufgedrückt wird, so kann der Untersuchende (Arzt) an der Teilung die Größe des ausgeübten Druckes ablesen und den Druck entsprechend regeln, wie er ihn braucht. Am Ende der Büchse 4 ist eine lUemmschraube 9 angebracht, so daß der in die axiale Bohrung io der Büchse 4 eingesteckte Leitungsdraht befestigt werden kann. Da der Stiel 2 mit der Büchse 4 in leitender Verbindung steht, so geht der Strom vom Leitungsdraht durch Büchse 4 und Stange 2 zum Knopf i und tritt an der berührten Stelle in den Körper des zu Untersuchenden.That on the body part. to be attached end i of the electrode in. Formeines spherical button made of slightly moisture-absorbing material sits firmly on the cylindrical Handle e made of steel, the front in, a brass sleeve 3 and at the back. in one of those 4, is performed, which in a handle 5 made of non-conductive material, for. B. hard rubber., put. The handle z is axial with the sleeve 3. slidable in the handle and surrounded by a spiral spring 6, which is back against the forehead of the handle fixed sleeve 4, in front against the forehead of the sleeve 3, with which the handle is connected by a pointer pin 7 inserted radially. This pointer pen slides in an axial displacement of the handle 2 in a slot 8 of the handle, on both sides of which there is a graduation (see Fig. 2), its zero point is at the front end position of the pointer pen. If now the button i on the the part of the body to be examined is pressed, the examiner (doctor) can read off the magnitude of the pressure exerted on the graduation and the pressure accordingly regulate how he needs it. At the end of the sleeve 4 there is a locking screw 9, so that the lead wire inserted into the axial bore io of the sleeve 4 is fastened can be. Since the handle 2 is in conductive connection with the sleeve 4, so goes the current from the lead wire through sleeve 4 and rod 2 to button i and comes on the touched point in the body of the person to be examined.
