Analyzer

An analyzer comprising: an assembly holder for holding a reagent-containing assembly comprising an opening and a lid member for opening and closing the opening; an opening-closing section for opening and closing the opening by linearly moving the lid member in a reciprocating manner to substantially horizontal directions; a reagent suctioning section for suctioning reagent by inserting a pipette into the reagent-containing assembly through the opening; and an analyzing section for analyzing an analyzing specimen comprising a sample and the reagent is disclosed. A reagent-containing assembly and reagent suctioning method are also disclosed.

Analyzer, reagent-containing assembly, and reagent suctioning method

A reagent-containing assembly comprising: a reagent-accommodating section comprising an opening sealed by a seal member; and a seal-opening section comprising a breaking portion for breaking the seal member, and a suction hole configured to provide access to the reagent-accommodating section; wherein the reagent-accommodating section and the seal-opening section are configured for detachable engagement with each other is disclosed.

Reagent-containing assembly

An automatic sample analyzer includes: a pipette, a pipette driving device which moves the pipette to a sample vessel present in a predetermined position to cause the pipette to suck up a sample from the sample vessel, and then moves the pipette to an open vessel provided in another predetermined position to cause the pipette to discharge the sample into the open vessel, and an analyzing section for analyzing the discharged sample, the pipette driving device comprising a vertically movable main arm and an elongated guide arm cantilevered by the main arm and extending horizontally, the guide arm having a smaller flexural rigidity than the main arm, wherein the main arm vertically moves the pipette when the sample is to be sucked up from the sample vessel, and the guide arm guides the pipette to the open vessel and then vertically moves the pipette when the sample is to be discharged into the open vessel.

Automatic sample analyzer and its components

A small, inexpensive, and easy-to-use automated immunochemical anlayzer is provided. The automated immunochemical analyzer comprises at least one reaction plate of disposable type forming a plurality of containers in one body, a table that can be drawn out for mounting the reaction plates, a table can be drawn out for mounting specimen racks, a reagent thermostatic unit, a reaction thermostatic unit, a reaction plate holding part, an apparatus for aspirating and discharging sample liquid, and an XY moving part mounting the reaction plate holding part and the apparatus for aspirating and discharging sample liquid. First, by the XY moving part, the holding part holds the reaction plate before use from the table for mounting the reaction plates and moves up to the reaction thermostats unit. Consequently, by the XY moving part, the apparatus for aspirating and discharging sample liquid is moved reciprocally among the specimen rack, reagent thermostatic unit, and reaction thermostatic unit, thereby distributing specimens and reagents to the reaction plate. THe distributed liquid is kept in a thermostatic state, and shaken and agitated, thereby promoting the antigen-antibody reaction. The reaction liquid is sample by the apparatus for aspirating and discharging sample liquid, and is measured.

Automated immunochemical analyzer

An apparatus for aspirating and discharging a specific volume of liquid sample, such as specimen and reagent, has a reaction plate serving a holding function and having a plurality of reaction containers, is provided which is low in cost and compact in design. On one side of a belt applied on two pulleys driven by one driving source an arm for holding a pipet is provided, while a reaction plate holding part is mounted on the other side of the belt (112), thereby constructing an apparatus for aspirating and discharging a liquid sample. When the arm ascends, the holding part descends, and when the arm descends, the holding part ascends. Thus, the arm and holding part are moved mutually in opposite directions by one driving source.
