Description
Stechapparat zur Blutentnahme Die Erfindung betrifft einen Stechapparat zur Blutentnahme mit am Ende eines federbelasteten Stempels angebrachter auswechselbarer Lanzette. Lancing device for taking blood The invention relates to a lancing device for taking blood with an exchangeable one attached to the end of a spring-loaded stamp Lancet.
Derartige Stechapparate mit fest eingebauten Messern, Nadeln oder Lanzetten sind seit langem bekannt. in der Praxis mußte man jedoch die Erfahrung machen, daß mit Stechapparaten dieser Bauart häufig Infektionen und Krankheitserreger (insbesondere Viren) übertragen werden. Diese häufige Folgeerscheinung kann mit einer normalen Desinfektion nicht bes eitigt werclen. Eine allein sichere Hitzesterilisierung ist aber aus Zeitgrunden nicht durchführbar.Such lancing devices with built-in knives, needles or Lancets have long been known. in practice, however, one had to have experience make that with lancing devices of this type often infections and pathogens (especially viruses) are transmitted. This common consequence can be with not removed after normal disinfection. Heat sterilization alone is safe but is not feasible due to time constraints.
Man ist deshalb in letzter Zeit von der Verwendung der Stechapparate mit fester Lanzette ganz abgegangen und verwendet einzelne in Papier steril verpackte Lanzetten, die nach dem Einstich (z. B. in den Finger) alsbald weggrfeu werden.The use of lancing devices has therefore recently been abandoned with a firm lancet completely dislodged and used individual sterile-wrapped paper Lancets after the Puncture (e.g. in the finger) immediately gone away will.
Bei dieser Methode des Einstichs von Hand kommt es weitgehend auf die Geschicklichkeit des Untersuchers an, wie tief der Einstich erfolgt. Ein weiterer Nachteil dieser Methode liegt darin, daß man jede Lanzette von Hand aus der Verpackung entfernen muß, wobei sehr leicht die Sterilität verletzt werden kann.With this method of puncturing by hand, it largely comes up the skill of the examiner on how deep the puncture is made. Another The disadvantage of this method is that each lancet is removed from the packaging by hand must remove, and the sterility can very easily be violated.
Aufgabe der Erfindung ist es, einen Stechapparat zu konstruieren, der die vorgenannten Nachteile nicht aufweist und für jeden Stechvorgang eine neue sterile Lanzette bereitstellt.The object of the invention is to construct a lancing device, which does not have the aforementioned disadvantages and a new one for each lancing process providing sterile lancet.
Der erfindungsgemäße Stechapparat ist zu diesem Zweck gekennzeichnet durch ein in den Stechapparat einsetzbares Magazin mit einzeln steril verpackten Lanzetten und einen mit dem Stempel verbundenen Mitnehmer, an dem die jeweils vorderste Lanzette im Magazin derart anliegt, daß bei Betätigung des Stempels die Lanzettenspitze die sterile Verpackung durchstößt.The lancing device according to the invention is marked for this purpose through a magazine that can be inserted into the lancing device with individually sterile packs Lancets and a driver connected to the punch, on which the foremost The lancet rests in the magazine in such a way that when the stamp is actuated, the lancet tip punctures the sterile packaging.
Auf diese Weise wird jede Berührung der Lanzette von Hand vor dem Einstechvorgang mit Sicherheit vermieden, wodurch die Übertragung von Infektionen und Krankheitserregern weitgehend verhindert wird.This way, every touch of the lancet by hand is prior to the The piercing process is avoided with certainty, thereby preventing the transmission of infections and pathogens is largely prevented.
Für das Zusammenwirken des Mitnehmers mit den, einzelnen Lanzetten im Magazin sind verschiedene Lösungen denkbar.For the interaction of the driver with the individual lancets Various solutions are conceivable in the magazine.
Nach einer bevorzugten Ausführungsform der Erfindung weist der Mitnehmer zwei Klauen auf, die beim Spannen des Stempels die Verpackung der anliegenden Lanzette hochziehen, wodurch die Lanzettenspitze die Verpackung durchstößt. In der höchsten Stellung des Stempels greift ein Zapfen des Mitnehmers in eine Einkerbung der Lanzette, so daß bei der Auslösung des Stempels die Lanzette mitgenommen wird. Ein Magnet am Mitnehmer gibt der Lanzette den nötigen llalt. Nach dem Stechvorgang wird die Lanzette von liand oder mittels eines Auswerfers abgezogen.According to a preferred embodiment of the invention, the driver two claws that, when the stamp is tensioned, the packaging of the adjacent lancet pull up, causing the lancet tip to pierce the packaging. In the highest In the position of the stamp, a pin of the driver engages in a notch in the lancet, so that when the punch is triggered, the lancet is taken along. A magnet on the driver gives the lancet the required length. After the lancing process, the Lancet withdrawn from liand or by means of an ejector.
Gemäß einer anderen Ausführungsform der Erfindung enthält das magazin ein Band mit einzelnen nebeneinander liegenden Lanzetten, die je etwa reißnagelartig mit breitem Kopf ausgebildet sind. Bei jedem Spannen des Stempels wird das magazinband mittels eines Reibrades od. dgl. so weit gefördert, da£S eine neue Lanzette vor dem Stempel liegt. Nach Auslösung schd t der niedergehende Stempel auf den breiten Kopf der Lanzette tind drückt dadurch deren Spitze durch die Verpackung nl in den Finger od. dgl.According to another embodiment of the invention, the magazine contains a band with individual lancets lying next to one another, each roughly like a thumbtack are formed with a broad head. Each time the punch is tensioned, the magazine band is promoted by means of a friction wheel or the like so far that a new lancet is available the stamp. After triggering, the falling stamp on the wide one is damaged The head of the lancet tind pushes its tip through the packaging nl into the Finger or the like
Auch Magazine mit aufeinanderliegenden, durch die Schwerkraft geförderten Lanzetten sind anwendbar.Also magazines with one on top of the other, conveyed by gravity Lancets are applicable.

Hierin sind: Fig. 1 eine Seitenansicht, teilweise im Schnitt, eines erfindungsgemäßen Stechapparates, Fig. 2 die Darstellung einer Lanzettt mit ihrer Verpackung, Fig. 3 eine Darstellung des Mitnehmers im vergrößerten Maßstab und Fig. 4 die Darstellung eines Magazins.An embodiment of the invention is described below to Jiand Drawing described. Herein are: FIG. 1 a side view, partly in section, of a lancing device according to the invention, FIG. 2 shows a representation of a lancet with their packaging, FIG. 3 shows the driver on an enlarged scale and FIG. 4 shows the illustration of a magazine.
In einem Gehäuse 5 befindet sich ein Stempel 1, der von einer Schraubenfeder 2 nach unten gedrückt wird. Zum Spannen wird der Stempel 1 so weit hochgezogen, daß seine Nase 4 hinter einen entsprechenden Vorsprung des Gehäuses greift; durch einen Auslöserbügel 3 kann die Nase 4 in das Gehäuse geknickt werden, wodurch der Stempel mit beträchtlicher Geschwindigkeit nach unten schnellt.In a housing 5 there is a stamp 1, which is operated by a helical spring 2 is pressed down. For clamping, the punch 1 is pulled up so far that that his nose 4 engages behind a corresponding projection of the housing; by a trigger bracket 3, the nose 4 can be bent into the housing, whereby the The punch shoots down at a considerable speed.
Am unteren Ende des Gehäuses 5 befindet sich ein RUSeClISelbares Magazin 8, das durch eine abnehmbare Kappe 11 in seiner Lage gesichert ist. Zwischen der Kappe 11 und einer stirnseitigen Öffnung des Magazins 8 befindet sich eine Druckfeder 9, die den Inhalt des Magazins nach vorn gegen den Mitnehmer 6 drückt.At the lower end of the housing 5 there is a removable magazine 8, which is secured by a removable cap 11 in its location is secured. Between the cap 11 and a front opening of the magazine 8 is located a compression spring 9 which presses the contents of the magazine forward against the driver 6.
Das Magazin 8 enthält eine Mehrzahl einzeln verpackter Lanzetten 12, die am oberen Ende eine Einkerbung 13 und am unteren Ende eine scharfe Spitze 14 aufweisen. Jede Lanzette 12 befindet sich in einer sterilen Verpackung 15, die im wesentlichen aus einer dünnen, verhLiltnismäßig leicht verletzbaren Hülle besteht, jedoch beiderseits der Lanzettenspitze 14 mit einer Verstärkung 16 versehen ist.The magazine 8 contains a plurality of individually packaged lancets 12, which has a notch 13 at the upper end and a sharp point 14 at the lower end exhibit. Each lancet 12 is in a sterile packaging 15, which is in the consists essentially of a thin, relatively easily vulnerable shell, however, a reinforcement 16 is provided on both sides of the lancet tip 14.
Das Magazin 8 weist an seiner Unterseite und an seinen beiden Stirnseiten Schlitze 17, 18 und 19 auf und ist unmittelbar hinter der vorderen Stirnwand mit einem Austrittsschlitz 20 für die jeweils vorderste Lanzette versehen. Stattdessen kann auch die vordere Stirnwand abnehmbar ausgebildet sein.The magazine 8 has on its underside and on both of its front sides Slots 17, 18 and 19 open and is immediately behind the front end wall with an exit slot 20 for each of the foremost lancets. Instead of this the front end wall can also be designed to be removable.
Der am unteren Ende des Stempels 1 angeordnete Mitnehmer 6 besitzt einen Zapfen 21, der in die obere Eiiilerbnng 13 der anLiegenden Lanzette 12 eingreifen kann, und zwei untere Klauell 22, die sich beim hochziehen des Stempels L von unten gegen die Versteifungen 16 der Verpackung 15 legen.The driver 6 arranged at the lower end of the stamp 1 has a pin 21, which engages in the upper Eiiilerbnng 13 of the adjacent lancet 12 can, and two lower claws 22, which are when the punch L is pulled up from below Place against the stiffeners 16 of the packaging 15.
Beim weiteren Spannen des Stempels ziehen die Klauen 22 den unteren Teil der Verpackung mit den Versteifungen 16 nach oben, wodurch die Spitze 14 den dünneren Mittelteil der Verpackung zwischen den Versteifungen 16 durchstößt.As the punch continues to be tensioned, the claws 22 pull the lower part of the package with the stiffeners 16 facing up, making the top 14 penetrates the thinner middle part of the packaging between the stiffeners 16.
Erst wenn der Stempel so weit angehoben wurde, daß die Lanzettenspitze 14 freigelegt ist, greift der Zapfen 91 in die Einkerbung 13. Dadurch kann die Feder 9 die Lanzette- 12 so weit vorschieben, bis diese fest von oben und unten durch den Zapfen 21 und die Klauen 22 gehalten wird und außerdem durch einen in dem Mitnehmer 6 eingelassenen Magneten 7 fixiert wird.Only when the punch has been raised so far that the lancet tip 14 is exposed, the pin 91 engages in the notch 13. This allows the spring 9 Advance the lancet 12 until it is firmly through from above and below the pin 21 and the claws 22 is held and also by one in the driver 6 embedded magnets 7 is fixed.
Wird anschließend der Stempel 1 mittels des Auslösers 3 auselöst, so schlägt er unter der Wirkung der gespanllte Feder 2 nach unten und nimmt die Lanzette 12 samt ihrer Verpackung mit, so daß die freiliegende Spitze 14 in die Haut des Patienten, auf die der Stechapparat aufgesetzt: ist, eindringt.If the stamp 1 is then triggered by means of the trigger 3, so he strikes under the action of the Spanllte spring 2 down and takes the Lancet 12 and its packaging with so that the exposed tip 14 in the The patient's skin on which the lancing device is placed penetrates.
Nach dem Abheben des Stechapparates kann die benutzte Lanzette von Hand oder mittels eines nicht dargestellten Auswerfers abgezogen werden. Gleichzeitig wird durch die Felde 9, an deren Stirnseite sich eine Druckplatte 24 befindet, die nächste im Magazin 8 befindliche Lanzette 12 nachgedrückt.After lifting the lancing device, the used lancet can be removed from Can be withdrawn by hand or by means of an ejector (not shown). Simultaneously is through the field 9, on the end face of which there is a pressure plate 24, the The next lancet 12 located in the magazine 8 is pushed in.
