Description

Vorrichtung zur Entnahme von Blutproben aus dem menschlichen oder tierischen Körper. Die Erfindung betrifft eine Vorrichtung zur Entnahme von Blut aus (lein menschlichen oder tierischen Körper zum Zwecke der Blutuntersuchung. Derartige Vorrichtungen sind bereits bekannt, doch haben sie den Nachteil, daß nur eine Bewegung des Einstichiverkzeuges, entweder seine Einführung in den Körper oder seine Zurückführung aus demselben, durch Federwirkung erfolgt, während die andere Bewegung von Hand ausgeführt werden muß, wodurch dein Patienten leicht Schmerzen zugefügt «-erden können.Device for taking blood samples from the human or animal body. The invention relates to a device for withdrawing blood from (no human or animal body for the purpose of blood testing. Such Devices are already known, but they have the disadvantage that only one movement of the puncture tool, either its introduction into the body or its return from the same, by spring action, while the other movement is done by hand must be carried out, thereby easily inflicting pain on your patient can.

Diesem Nachteil wird durch die Erfindung abgeholfen.This disadvantage is remedied by the invention.

Im Gegensatz zu den bekannten Vorrichtungen erfolgen bei dem Erfindungsgegenstand beide Bewegungen des Messers, das Einführen sowohl als auch das Herausziehen aus dem Körperteil, durch Federwirkung. Nach der Erfindung geschieht dies dadurch, daß beim Auslösen der gespannten Feder das Messer nicht nur in die Ruhelage zurückkehrt, sondern infolge des Beharrungsvermögens bis zu einem Anschlag weiter vorschnellt, wobei es zum Einstich in den Körper kommt, und dann erst selbsttätig in die Ruhelage zurückkehrt.In contrast to the known devices, the subject matter of the invention takes place both movements of the knife, both insertion and withdrawal the body part, by spring action. According to the invention, this is done in that when the tensioned spring is released, the knife not only returns to the rest position, but as a result of the persistence it rushes forward to a stop, whereby it comes to puncture into the body, and only then automatically into the rest position returns.

Die Wirkung in der Ausdehnung der Feder bzw. der selbsttätigen Zusammenziehung kann noch dadurch erhöht werden, daß an dem einen Ende der Feder ein Gewicht angeordnet wird. Durch einen am oberen Teil des Instrumentes verstellbar angeordneten Anschlag kann die Tiefe des Messerstiches abgestimmt werden.The effect in the expansion of the spring or the automatic contraction can be further increased in that a weight is arranged at one end of the spring will. With an adjustable stop on the upper part of the instrument the depth of the knife stab can be adjusted.

Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt. Abb. r zeih die Vorrichtung in ihrer Ruhelage, während in Abb. 2 der Erfindungsgegenstand in der Stellung gezeigt ist, in der die das Messer bewegende Feder gespannt ist.The invention is shown in an exemplary embodiment in the drawing. Fig. R shows the device in its rest position, while in Fig. 2 the subject of the invention is shown in the position in which the spring moving the knife is tensioned.

Die Anordnung der einzelnen Teile der neuen Vorrichtung und die Wirkungsweise ist folgende: In dem hülsenartig ausgebildeten Teil a ist die Aufzugstange b angeordnet, die an ihrem unteren Ende mit einem Gewicht c versehen ist. An dem Gewicht c ist das Messer d befestigt. Zwischen dem Gewicht c und der Lagerbuchse e der Stange b ist die Feder f gelagert, die einerseits an der Lagerbuchse e und andererseits am Gewicht c befestigt ist. An dem Gewicht c ist ferner eine Blattfeder g angeordnet, deren oberes, mit Nippel h versehenes Ende in einem Schlitz i der Hülse a geführt wird. Der Schlitz i. endet in einer kreisförmigen Verbreiterung h, in die das untere- Teil l des Nippels h beim Spannen der Feder f einschnappt. Durch Druck auf den Nippel h wird die Sperrung aufgehoben und die mit Gewicht versehene Feder entspannt, so daß das am Gewicht c befestigte Messer aus der Hülse a heraustritt, in den Körperteil eindringt und durch die Zusammenziehung der Feder über die 'Normalstellung der entspannten Feder hinaus in seine Ruhelage zurückgeführt wird.The arrangement of the individual parts of the new device and the mode of operation is as follows: In the sleeve-like part a, the elevator rod b is arranged, which is provided with a weight c at its lower end. The knife d is attached to the weight c. The spring f is mounted between the weight c and the bearing bushing e of the rod b and is fastened on the one hand to the bearing bushing e and on the other hand to the weight c. A leaf spring g is also arranged on the weight c, the upper end of which is provided with a nipple h and is guided in a slot i of the sleeve a. The slot i. ends in a circular widening h, into which the lower part l of the nipple h snaps when the spring f is tensioned. By pressing on the nipple h, the lock is released and the weighted spring is relaxed, so that the knife attached to the weight c emerges from the sleeve a, penetrates the body part and through the contraction of the spring beyond the normal position of the relaxed spring is returned to its rest position.

Durch die an der Stange h angebrachte verstellbare Mutter na, die als Anschlag dient, kann die Tiefe des Messerstiches abgestimmt werden. With the adjustable nut na attached to the rod h, which serves as a stop, the depth of the knife stab can be adjusted.
