Abstract

The device is claimed for handling of liq. and solid samples, partic. in analysis automatic appts. For each new sample a fresh piece (e.g. hose, fibre or wire) from a storage roll (1) is used. Where a hose is used for liq. samples, the cut-off hose piece is accommodated in a connection which forms a gastight connection to a controlled feed syringe. The end of the hose storage roll can also be connected in a gastight fashion with the controlled feed syringe. ADVANTAGE - The system allows a simpler and cheaper handling of samples for analysis.

Description

Es ist bekannt, die Handhabung flüssiger und fester Proben zur Analyse mit geeigneten Handhabungshilfen vorzunehmen. Diese werden dabei mit der Probe verun­ reinigt und müssen entweder weggeworfen oder gerei­ nigt werden, wenn Verschleppungen nicht toleriert werden können. Vor allem, wenn diese Vorgänge auto­ matisiert werden, sind sowohl zeitraubende Spül- und Trockenvorgänge als auch die platzraubende Bereit­ stellung einer großen Anzahl von Einmalprobenträgern sehr hinderlich.It is known to handle liquid and solid Samples for analysis with suitable handling aids to make. This will cause the sample to be contaminated cleans and either have to be thrown away or trashed be taken into account if procrastination is not tolerated can be. Especially when these operations are auto are both time-consuming rinsing and Drying processes as well as the space-consuming ready provision of a large number of single-use sample carriers very cumbersome.

Der im Patentanspruch 1 angegebenen Erfindung liegt die Problemstellung zugrunde, die Proben in automa­ tischen Systemen einfacher und kostengünstiger zu handhaben.The invention specified in claim 1 lies based on the problem, the samples in automa table systems easier and cheaper handle.

Diese Problemstellung wird dadurch gelöst, daß für jede neue Probe ein neues Stück eines Probenaufneh­ mers (z. B. Schlauch, Faden oder Draht) verwendet wird, das von einer Vorratsrolle bereitgestellt und entweder vor oder nach der Probenhandhabung abge­ schnitten wird.This problem is solved in that for each new sample a new piece of a sample holder mers (e.g. hose, thread or wire) is used is provided by a supply roll and either before or after sample handling will cut.

Die mit der Erfindung erzielten Vorteile sind:The advantages achieved with the invention are:

  • a. kostengünstige Bereitstellung des Probenaufnehmersa. cost-effective provision of the sampler
  • b. einfache, gut automatisierbare Handhabungb. simple, easy to automate handling
  • c. geringer Platzbedarf insbesondere im Arbeitsbereich des Automatenc. low space requirement, especially in the work area of the machine

Vorteilhafte Ausgestaltungen der Erfindung sind in den Patentansprüchen 2 u. 3 angegeben. Dabei erfolgt für flüssige Proben die Probenaufnahme und Probenab­ gabe mit einer luftgefüllten Dosierspritze, die entweder an dem schon abgeschnittenen Schlauchstück (Patentanspruch 2) oder am Ende des Schlauchvorrates (Patentanspruch 3) angeschlossen ist.Advantageous embodiments of the invention are shown in claims 2 u. 3 specified. This is done for liquid samples the sample intake and samples with an air-filled syringe, the either on the already cut piece of hose (Claim 2) or at the end of the hose supply (Claim 3) is connected.

Ein Ausführungsbeispiel der Erfindung für die Hand­ habung flüssiger Proben gemäß Patentanspruch 2 ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention for the hand has liquid samples according to claim 2 shown in the drawing and is shown below described in more detail.

Aufbau:Construction:

Die Zeichnung zeigt einen Ausschnitt eines automati­ schen Analysegerätes für flüssige Proben, in dem eine Probe für unterschiedliche Untersuchungen auf mehrere Gefäße verteilt wird. Unter der Arbeitsflä­ che des Analyseautomaten sind die Schlauchvorrats­ rolle 1 und die Rücklaufsperre 2 angebracht. In Höhe der Arbeitsfläche ist die Abschneidevorrichtung 3 angebracht. Der Schlauch läuft von der Vorratsrolle durch die Rücklaufsperre in die Abschneidevorrich­ tung. Oberhalb der Arbeitsfläche befinden sich die Dosierspritze 5, die mit einer Spitze 4 zur gas­ dichten Aufnahme des abgeschnittenen Schlauchstücks versehen ist und in mehreren Koordinaten verfahren werden kann. Auf der Arbeitsfläche befinden sich Probengefäße 6, Untersuchungsgefäße 7 und der Ab­ streifer 8. Unterhalb des Abstreifers ist ein Auf­ fanggefäß 9 zur Aufnahme der verbrauchten Schlauch­ stücke angebracht. The drawing shows a section of an automatic analyzer's for liquid samples, in which a sample is distributed over different vessels for different tests. Under the work surface of the automatic analyzer, the hose supply roll 1 and the backstop 2 are attached. The cutting device 3 is attached at the level of the working surface. The hose runs from the supply roll through the backstop into the cutting device. Above the work surface are the metering syringe 5 , which is provided with a tip 4 for gas-tight holding of the cut-off piece of tubing and can be moved in several coordinates. On the work surface there are sample vessels 6 , examination vessels 7 and the scraper 8 . Below the scraper on a receptacle 9 for receiving the used hose pieces is attached.

Funktionfunction

Die Spitze 4 wird in das Schlauchende eingeschoben. Dabei verhindert die Rücklaufsperre 2 ein Zurückrut­ schen des Schlauches. Durch eine geeignete Formge­ bung der Spitze 4 wird diese gasdicht und genügend fest mit dem Schlauch verbunden. Der Schlauch wird ein Stück herausgezogen und abgeschnitten. Das Schlauchende wird nun in das Probengefäß 6 eingefah­ ren und die benötigte Menge der flüssigen Probe mit der Dosierspritze 5 angesaugt. Die Länge des Schlauchstücks ist so gewählt, daß nur der Schlauch von der Probe benetzt wird. Dann wird die Spitze 4 über die Untersuchungsgefäße 7 gefahren und dort jeweils die vorgesehene Menge ausgestoßen. Das Schlauchstück wird dann am Abstreifer 8 von der Spitze abgestreift und fällt in den Abfallbehälter 9.The tip 4 is inserted into the end of the hose. The backstop 2 prevents the hose from slipping back. By a suitable shape of the tip 4 this is gastight and sufficiently firmly connected to the hose. The tube is pulled out a little and cut off. The end of the hose is now inserted into the sample vessel 6 and the required amount of the liquid sample is sucked in with the metering syringe 5 . The length of the tube piece is chosen so that only the tube is wetted by the sample. Then the tip 4 is moved over the examination vessels 7 and the intended quantity is ejected there. The piece of hose is then stripped from the tip on the scraper 8 and falls into the waste container 9 .
