Abstract
The goniometer for measuring finger reflex and hyperextension has a measuring plate (MP) and a pair of cooperating measuring arms (CM, KM). The longer of these is sufficiently long to allow it to be supported against the hand, with the measuring plate rotated by the index finger into a required position. An angular scale is marked on each side of the measuring plate (MP) the shorter measuring arm (KM) offset by 40 degrees from the scale zero point. A pointer (2) on either side of the measuring plate (MP) is coupled to the longer measuring arm (LM) with a fixation screw (FS) providing the rotation axis for the measuring plate (MP) and allowing the frictional resistance between the longer measuring arm (LM) and the measuring plate (MP) to the adjusted. ADVANTAGE - Allows single-handed use.
Description
BESCHREIBUNG
Bei rheumatischen Erkrankungen und anderen Gelenkkrankheiten nimmt die Möglichkeit, die Fingerglieder zu beugen im Vergleich zu einer gesunden Hand ab. Für den behandelnden Arzt ist es wichtig zu wissen, ob diese Flexibilität bei seinem Patient abnimmt, stationär bleibt oder zunimmt und damit gar eine Besserung eintritt. Dazu sind Messungen in bestimmten Zeitabständen erforderlich, die der behandelnde Arzt in seine Patientenkarte eintragen kann.
Die Erfindung hat sich zur Aufgabe gestellt ein Instrument zu schaffen, das mit einer einzigen Hand geführt werden kann, das einfach aufgebaut und bequem in der Handhabung ist. Insbesondere soll auch eine präzise und einfache Messung der Hyperextension auf der Dorsalseite der Finger möglich sein.
Die Erfindung löst diese Aufgabe mit einem Instrument, das die Merkmale des Patentanspruches 1 aufweist. In der beigefügten Zeichnung ist ein Ausführungsbeispiel des erfindungsgemässen Instrumentes dargestellt und an Hand davon dessen Handhabung erläutert.
Die Zeichnung zeigt:
Fig. 1 eine vereinfachte Darstellung eines bekannten Instrumentes;
Fig. 2 eine vereinfachte Darstellung des erfindungsgemässen Instrumentes;
Fig. 3 die Verwendung des Instrumentes nach Fig. 2 bei der Messung der Flexion eines Fingers;
Fig. 4 die Verwendung des Instrumentes nach Fig. 2 bei der Messung einer Hyperextension.
Das in Figur 1 dargestellte Instrument hat eine Messplatte MP mit einer Skalaeinteilung von 0c bis 1800. An der Messplattenseite mit dem Skalawert 0 ist ein kurzer Messschenkel KM angebracht. Der lange Messschenkel LM, der durch einen dicken Strich angedeutet ist, ist im Zentrum der halbrunden Messplatte schwenkbar angelenkt und geht in einen Zeiger Z über. Dieses bekannte Instrument ist unpraktisch weil zu seiner Betätigung zwei Hände erforderlich sind.
Die Fingerbeugung-Überstreckungen können nur durch einen Lagewechsel des Instrumentes von der Dorsalseite auf die Volarseite gemessen werden. Das Messen ist umständlich und weniger genau.
Figur 2 zeigt das erfindungsgemässe Gerät in vereinfachter Darstellung. Es hat einen langen Messschenkel LM, der in einen fest damit verbundenen Zeiger übergeht.
Der Zeiter Z schliesst gegenüber dem langen Messschenkel einen Winkel von etwa 1400 ein. Liegt die radiale Kante der Messplatte MP, welche den kurzen Messschenkel KM bildet, in der Verlängerung des langen Messschenkels LM, zeigt der Zeiger Z auf 00.
Figur 2 zeigt auch die Handhabung des Instrumentes.
Der lange Messschenkel LM wird von Daumen und Mittelfinger gehalten und mit Hilfe des Zeigfingers lässt sich die Messplatte MP um die Fixationsschraube FS drehen. Die Schraube erlaubt eine Einstellung des gewünschten Reibungswiderstandes. Die Skalneinteilung ist auf beiden Seiten der Messplatte angebracht und der lange Messschenkel ist dementsprechend auch mit einem zweiten Zeiger versehen, der eine Ablesung auf der Rückseite erlaubt. Dies erlaubt ein bequemes Messen der Finger-Flexion für Rechtshänder sowie für Linkshänder.
Figur 3 zeigt eine Verwendung des Instrumentes bei der Messung der Fingerflexion eines Patienten. In dieser Zeichnung ist der Übersichtlichkeits halber die Hand des Arztes weggelassen, der bei der Messung das Gerät wie in Figur 2 dargestellt ist, mit einer Hand festhält und betätigt.
Figur 4 schliesslich zeigt eine Verwendung des Instrumentes bei einer Messung der Hyperextension am Zeigfinger eines Patienten.
Wie aus diesen beiden letzten Figuren ersichtlich, können die Flexion wie die Hyperextension, beide bei dorsalem Anlegen des langen Messschenkels auf den Handrücken gemessen werden.
DESCRIPTION
With rheumatic diseases and other joint diseases, the ability to bend the limbs decreases compared to a healthy hand. It is important for the attending physician to know whether this flexibility decreases with his patient, remains inpatient or increases, and thus even improves. For this purpose, measurements at certain time intervals are required, which the treating doctor can enter on his patient card.
The invention has set itself the task of creating an instrument that can be operated with a single hand, which is simple and easy to use. In particular, a precise and simple measurement of the hyperextension on the dorsal side of the fingers should also be possible.
The invention solves this problem with an instrument having the features of claim 1. In the accompanying drawing, an embodiment of the instrument according to the invention is shown and the handling thereof is explained on the basis thereof.
The drawing shows:
1 shows a simplified illustration of a known instrument;
2 shows a simplified illustration of the instrument according to the invention;
3 shows the use of the instrument according to FIG. 2 in measuring the flexion of a finger;
Fig. 4 shows the use of the instrument of Fig. 2 in the measurement of hyperextension.
The instrument shown in FIG. 1 has a measuring plate MP with a scale division from 0c to 1800. A short measuring leg KM is attached to the measuring plate side with the scale value 0. The long measuring leg LM, which is indicated by a thick line, is pivotally articulated in the center of the semicircular measuring plate and merges into a pointer Z. This known instrument is impractical because two hands are required to operate it.
The finger flexion hyperextensions can only be measured by changing the position of the instrument from the dorsal side to the volar side. Measuring is cumbersome and less accurate.
Figure 2 shows the device according to the invention in a simplified representation. It has a long measuring leg LM, which merges into a pointer that is firmly connected to it.
The time Z encloses an angle of approximately 1400 with respect to the long measuring leg. If the radial edge of the measuring plate MP, which forms the short measuring leg KM, lies in the extension of the long measuring leg LM, the pointer Z points to 00.
Figure 2 also shows the handling of the instrument.
The long measuring leg LM is held by the thumb and middle finger and with the help of the index finger the measuring plate MP can be rotated around the fixation screw FS. The screw allows the desired frictional resistance to be set. The scale is attached to both sides of the measuring plate and the long measuring leg is accordingly also provided with a second pointer, which allows a reading on the back. This allows easy measurement of finger flexion for right-handed and left-handed users.
FIG. 3 shows the use of the instrument in the measurement of a patient's finger flexion. In this drawing, for the sake of clarity, the hand of the doctor is omitted, who holds the device with one hand and actuates it during the measurement as shown in FIG.
FIG. 4 shows the use of the instrument when measuring hyperextension on a patient's index finger.
As can be seen from these last two figures, the flexion and the hyperextension can both be measured with the long measuring leg placed dorsally on the back of the hand.
