摘要:
A detection device for detecting a substance to be detected contained in a specimen has a pipette that has a detachable pipette tip and that suctions or discharges a specimen in a container, a pipette-moving unit for moving the pipette, and a control unit for controlling the pipette and pipette-moving unit. The control unit controls the pipette and the pipette-moving unit so that the pipette suctions a portion of specimen in the container with the pipette-moving unit having moved the distal end of the pipette tip to a position (a) in the lower side of the container, and thereafter discharges in the container the specimen suctioned by the pipette to stir the specimen with the pipette-moving unit having moved the distal end of the pipette tip to a position (b) above the position (a).

La présente invention concerne un procédé d'identification bactérienne et de détermination de la sensibilité de bactéries à des antibiotiques, ainsi qu'un appareil et des supports de mesure pour la mise en oeuvre de ce procédé. Procédé consistant à introduire manuellement, au moyen d'un outil de prélèvement et de transfert, un volume donné de colonie bactérienne dans un récipient primaire (101) à réaliser automatiquement la dispersion de cette colonie bactérienne au sein d'un liquide pour constituer un inoculum précalibré dans ledit récipient primaire (101), à effectuer également automatiquement des transferts totaux ou partiels de cet inoculum précalibré entre ledit récipient primaire (1) et un ou plusieurs supports de mesure (104, 105), lesdits transferts étant réalisés sans que l'inoculum précalibré soit mis en contact avec un élément autre que, d'une part, un outil de prélèvement et de transfert (101' ; 101) et/ou le récipient primaire (101) et, d'autre part, son ou ses supports de mesure finaux (104, 105) et de telle manière que les quantités de bactéries transférées correspondent aux quantités requises pour les analyses à réaliser, à effectuer automatiquement la répartition de l'inoculum précalibré, éventuellement après l'avoir convenablement dilué pour aboutir à une calibration définitive, dans une ou plusieurs alvéoles (132, 137, 145) desdits supports de mesure (104, 105) contenant pour la plupart des réactifs appropriés et à faire des mesures sur le contenu desdites alvéoles (132, 137, 145) pendant ou à la fin d'une ou plusieurs incubations subies par l'inoculum dans lesdits supports de mesure (104, 105), les mesures relevées étant enregistrées par un moyen informatique (108) et traitées en vue de la caractérisation de la croissance des bactéries présentes dans l'inoculum, de leur identification et/ou de la détermination de leur sensibilité à différents antibiotiques.
摘要:
An object moving device includes: a first drive mechanism configured to move a head unit in a first direction and in a second direction that is orthogonal to the first direction in a horizontal direction; a second drive mechanism configured to move an illumination unit in the first direction; a third drive mechanism configured to move a camera unit in the first direction; and a control unit configured to control operations of the first, second, and third drive mechanisms. The control unit controls the first drive mechanism to move the head unit on a first path along a movement line. The control unit controls the second and third drive mechanisms to move the illumination unit and the camera unit on the first path between the first container and the second container. When the head unit and the illumination unit interfere with each other on the first path, the control unit implements control such that the head unit moves in the second direction and the head units moves in the first direction on a second path parallel to the first path.

Die Erfindung betrifft eine Probeneingabevorrichtung (1) mit einem einzigen Ansteckplatz (2) für die automatisierte Eingabe medizinischer Proben, vorzugsweise Proben von Körperflüssigkeiten und Qualitätskontrollmedien, aus unterschiedlichen Probengefäßen (3, 4). Erfindungsgemäß sind in der Eingabevorrichtung (1) Probentransportbehälter (7) angeordnet, welche jeweils eine Kanüle (8) aufweisen, die sowohl durch eine Öffnung (9) in ein offenes (3) als auch durch ein durchstechbares Verschlusselement (17) in ein geschlossenes Probengefäß (4) einführbar ist, sowie dass die Eingabevorrichtung (1) über Führungselemente (10) verfügt, die vor dem Einführen oder Einstechen der Kanüle (8) des Probentransportbehälters (7) in das Probengefäß (3, 4) führend und/oder zentrierend auf die Kanüle (8) zugreifen.
摘要:
A pipette (1) for absorbance measurement comprises a pipette (10) and a pipette adaptor (20) that includes a pipette holder (21) for receiving the end of the pipette (10) and a tip holder (22) for holding a tip (30). When interposed between the pipette (10) and the tip (30), the pipette adaptor (20) provides a space (20A) communicating with a hollow in the pipette (10) and a hollow in the tip (30). The pipette adaptor (20) further comprises a window (23) for introducing external test light into the internal space (20A), and a reflector (24) that reflects the test light introduced to the space (20A) through the window (23) so that the reflected light may travel through the hollow in the tip holder (22) toward a suction hole (31) for attracting a sample at the end of the tip (30).
摘要:
A cartridge, a fluid handling system, and methods that can be used for automated handling of fluids, such as blood. The cartridge is configured to obtain a fluid sample from a sealed container, e.g., a septum sealed container. In an embodiment, the cartridge can be in the form of a fluid receptacle comprising piercing means, a reservoir, a venting means, and a filling means. The venting means is configured to provide fluid communication between the container and surroundings. The venting means can be valved. The filling means is configured to provide fluid transfer between the container and the reservoir and can include a piston. The piercing means is configured to enter the sealed container. The fluid receptacle can be a component of an apparatus also including a support. The support can be configured to retain a plurality of fluid receptacles. In an embodiment, the present method can include a method for handling fluid samples with an automated system. The method can include removing sample fluid from a sample container into a fluid receptacle; venting the sample container with the fluid receptacle; and dispensing the sample fluid from the fluid receptacle into a second container.
摘要:
An analytical system and method that enables more efficient transport of movable devices (22) among stations (24, 25, 26). According to one aspect of the invention, the system and method permit operational timesharing of a transport mechanism (34) for the movable devices. According to another aspect of the invention, control of the transport mechanism is effected on an event-driven basis. The invention has particular application to an adaptive, motion and fluids system for automating the sample handling/management process associated with analytical processes and especially bioanalytical processes such as introducing samples into LC and HPLC systems.
