Description
Die Erfindung bezieht sich auf ein Blutentnahmegerät zur tropfenweisen Blutentnahme.The The invention relates to a blood collection device for dropwise blood collection.
Ein
derartiges Blutentnahmegerät

Patentanmeldung
Zur Durchführung von Blutuntersuchungen mit Hilfe von Teststreifen insbesondere für Blutzuckertests, genügt es, die Haut des Patienten an einer besonders dünnen, gut durchbluteten Stelle, insbesondere Fingerkuppe, mit einer Lanzette zu perforieren und aus der Perforationsstelle einen oder mehrere Bluttropfen zu entnehmen, die auf einen Teststreifen aufgetragen werden. Bei Diabetikern ist es zur täglichen Kontrolle des Blutzuckerwertes und der davon abhängigen Insulindosierung erforderlich, daß der Patient ohne ärztliche Hilfe die Bestimmung des Blutzuckerwertes selbst durchführen kann.to execution blood tests using test strips, especially for blood glucose tests, enough it, the patient's skin in a particularly thin, well-perfused area, especially fingertip, with a lancet to perforate and remove one or more drops of blood from the perforation site, which are applied to a test strip. In diabetics is it to the daily Control of the blood sugar value and the dependent insulin dosage required, that the Patient without medical Help can perform the determination of blood glucose itself.

Die Aufgabe der Erfindung besteht demgegenüber darin, ein Blutentnahmegerät der eingangs erwähnten Art zu schaffen, welches eine oftmalige Blutentnahme sowohl durch den Patienten selbst als auch in Kliniken bei verschiedenen Personen gestattet Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.The The object of the invention is in contrast, a blood collection device of the type mentioned to provide, which a frequent blood withdrawal both by the Patients themselves as well as in clinics in different persons This object is achieved by the characterizing Characteristics of claim 1 solved.
Vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Abstandshalters ergeben sich aus den Unteransprüchen.advantageous Embodiments and developments of the spacer according to the invention emerge from the dependent claims.
Die Erfindung geht von der Überlegung aus, im Kopf des Blutentnahmegerätes in trommelförmiges Magazin mit mehreren, über den Umfang verteilt angeordneten Lanzetten anzuordnen. Nach jedem „Schuß" wird das Magazin automatisch in die nächste Stellung mit einer frischen Lanzette gedreht, welche für den nächsten „Schuß" bereit steht. Auf diese Weise wird ein weiterer Anstich mit bereits benutzten Lanzetten sicher vermieden, was insbesondere bei Verwendung des erfindungsgemäßen Blutentnahmegerätes für verschiedene Personen wegen der damit verbundenen Infektionsgefahr wesentlich ist. Sobald die letzte frische Lanzette verbraucht ist, blockiert das Magazin. Das Magazin mit den verbrauchten Lanzetten wird dann entfernt und gegen ein neues Magazin ausgetauscht. Auf diese Weise läßt sich ein und dasselbe Blutentnahmegerät immer wieder mit neuen Magazinen für jeweils eine Vielzahl von bis zu 10 aufeinanderfolgenden Blutentnahmen pro Magazin benutzen, wodurch die Gerätekosten pro Blutentnahme wesentlich gegenüber dem eingangs erläuterten Stand der Technik gesenkt werden können.The Invention goes from consideration out, in the head of the blood collection device in drum-shaped Magazine with several, about To arrange arranged around the circumference arranged lancets. After every "shot" the magazine becomes automatically in the next Position rotated with a fresh lancet, which is ready for the next "shot" this way will be another puncture with already used lancets certainly avoided, which in particular when using the blood collection device according to the invention for various People because of the associated risk of infection essential is. As soon as the last fresh lancet is used up, it blocks Magazine. The magazine with the used lancets is then removed and exchanged for a new magazine. In this way can be one and the same blood collection device always with new magazines for each of a variety of use up to 10 consecutive blood samples per magazine, thereby reducing the equipment costs per blood sample significantly compared to the above-explained State of the art can be lowered.
Die Erfindung wird anhand eines Ausführungsbeispiels in den Zeichnungen näher erläutert. Es zeigt:The Invention is based on an embodiment closer in the drawings explained. It shows:
