Description

Mit der Zunahme von Blutprüfungen aller Art hat die Möglichkeit der Infektion durch die Vorrichtungen zur Entnahme von Blutproben kranker Personen zugenommen. Streng genommen sollten diese Vorrichtungen nach jedem Gebrauch sterilisiert werden. Das ist jedoch umständlich und zeitraubend und in der Praxis schwer ausführbar. With the increase in blood tests of all kinds the possibility of Infection by the devices for collecting blood samples from sick persons increased. Strictly speaking, these devices should be sterilized after each use. However, this is cumbersome and time-consuming and difficult to carry out in practice.

Es gibt bereits einen Blutentuahmeschnepper mit auswechselbarer Nadel. Bei dem befteffenden Modell soll jedoch die Nadel im allgemeinen erst ausgewechselt werden, wenn sie stumpf geworden ist. Zu diesem Zweck muß dann der Schnepperhalter auseinander genommen werden, was durch Drehen des Schaftes geschieht, aber nicht in steriler Weise gehandhabt werden kann. There is already a bleeding snipe with a replaceable needle. In the case of the befteffenden model, however, the needle should generally only be replaced when it has become dull. The Schnepperhalter must then be used for this purpose be taken apart, which is done by turning the shaft, but not can be handled in a sterile manner.

Im Gegensatz dazu erfolgt beim Erfindungsgegenstand das Auswechseln von Lanzetten durch ihr bloßes Aufsetzen auf einen Spitzenträger mittels einer sterilen Pinzette od. -dgl., ohne daß sonst irgendein Handgriff rtötig ist. Dadurch wird das Erfordernis ärztlich sterilen Vorgehens sicher gewahrt. In contrast, the subject of the invention is replaced of lancets by simply placing them on a tip carrier by means of a sterile Tweezers or the like, without any other manipulation being reddish. This will the requirement of a sterile medical procedure is safely met.

Die besondere Einrichtung entsprechend der Abb. I enthält im Schaft I eine Feder, die durch Ziehen am Knopf 2 gespannt wird. Der Auslösebügel 3 hhlt zunächst die gespannte Feder fest. Die auswechselbare Lanzette4 wird, wie der geze-icbnete Pfeil andeutet, auf den Dorn 5 aufgesetzt. Beim Vorschnellen im Gebrauch durch Auslösen des Bügels 3 wird dile Lanzette durch eine Ausbohrung im Kopf 6 des Schneppers geführt, der gleichzeitig ihr Abwerfen verhindert und ihre Einstichtiefe regelt, letzteres durch ein Innengewinde des Kopfes, das nach Bedarf einstellbar ist. The special device according to Fig. I contains in the shaft I a spring that is tensioned by pulling button 2. The release bracket 3 stops first tighten the tensioned spring. The interchangeable lancet4 is, like the one shown Arrow indicates, placed on the mandrel 5. When rushing forward in use by releasing the trigger of the bracket 3, the lancet is guided through a bore in the head 6 of the snapper, which at the same time prevents their shedding and regulates their penetration depth, the latter through an internal thread of the head, which can be adjusted as required.

Diese abnehmbarenlianzetteukönneu in tbeliebiger Anzahl und auf Vorrat sterilisiert und nach jeweils einmaligem Gebrauch ausgewechselt werden. This detachable lianzetteu can be new in any number and in stock sterilized and exchanged after each single use.

Bei der Ausführung nach Abb. 2 ist die Regelung der Einstichtiefe nach hinten verlegt. Dieser Schnepper besteht wieder aus Schaft oder Griff 1 mit darin untergebrachter Spannfeder, einem hindurchgehenden Kolben I2 mit einem Dorn, der in der Abbildung durch die aufgesetzte Lanzette verdeckt ist, und einem Auslösebügel 3. In dem Fenster des Kopfes 14 mit seinem Unterteil 4a sind zwei Federn ga, 5b zu sehen, die in eine untere Randnut der Lanzette eingreifen. Der Kolben 12 ist durch eine Auswerfhüllse IS hindurchgeführt. Das Einstellen der Einstichtiefe geschieht durch die Stellschraube 7. In the design according to Fig. 2, the regulation of the penetration depth is moved to the rear. This Schnepper again consists of shaft or handle 1 with Tension spring housed in it, a piston I2 going through with a mandrel, which is covered in the picture by the attached lancet, and a release bracket 3. In the window of the head 14 with its lower part 4a are two springs ga, 5b to see, which engage in a lower edge groove of the lancet. The piston 12 is passed through an ejector sleeve IS. The puncture depth is set through the adjusting screw 7.

Nach erfolgtem Einstich werden die Federn 5a, 5b durch Zurütkziehen des Kolbens I2 zusammengedrückt in den Kopfteil 4a hineingezogen, so daß die frei gewordene Lanzette durch die Auswerfhülse I6 ausgeworfen wird. Danach wird der Kolben 12 losgelassen, bis er in die Feder 3 einrastet und zu neuem Gebrauch gespannt ist. After the puncture has taken place, the springs 5a, 5b are pulled back of the piston I2 compressed into the head part 4a, so that the free The lancet that has become is ejected through the ejector sleeve I6. After that the piston 12 released until it snaps into spring 3 and is tensioned for new use.
