An automatic analyzer capable of improving maintainability by facilitating access to an interlock unit. The interlock unit includes an operation member configured to be movably supported between a lock position and a lock release position, and obstruct rotation to an open position of a cover; an electromagnetic driving unit configured to drive the operation member, and a driving connecting unit configured to connect the operation member and the electromagnetic driving unit and drive the operation member by conveying an operation of the electromagnetic driving unit to the operation member. The interlock unit is provided to be attachable and detachable to and from the housing.

Automatic analyzer

Provided is an automatic analyzer in which a linear movement unit and a rotational movement unit that access to a same location can be arranged in a same plane. The automatic analyzer includes a linear movement unit configured to access to an access point by a linear movement, a rotational movement unit configured to access to the access point by a rotational movement, and a control unit configured to control an operation of the linear movement unit and the rotational movement unit so that the linear movement unit and the rotational movement unit do not interfere with each other.

An interlock unit for preventing rotation from a closed position of a cover to an open position thereof, includes: a hollow case having a rectangular parallelepiped shape disposed at a position adjacent to an inner side surface of a casing, below an end part opposite to a support shaft at the closed position of the cover; an action member that is provided on an upper surface of the case, supported to be movable between a non-operating position and an operating position, and engaged with a protruding part provided on the cover at the operating position to inhibit the cover from rotating toward the open position; electromagnetic drive means provided below the action member to drive the action member; and drive connecting means for driving the action member by connecting the action member and the electromagnetic drive means and transmitting an operation of the electromagnetic drive means to the action member.

Interlock unit and automated analyzer equipped with same

The present invention comprises: an incubator diskupon which a plurality of reaction containers holding a reaction solution being an analyte and a reagent that have been mixed and reacted are mounted; a immunoassay unitthat measures the physical properties of the reaction solution; and a planning unitthat determines the order for measurement of analyte requested to be executed by the immunoassay unit. Measurement by the immunoassay unitincludes items having different measurement times. When measurement of sequence items having the longest measurement time will occur at least a prescribed number of times in a row, said prescribed number being at least two, the planning unitprovides at least one empty cycle after measurement has occurred at least the prescribed number of times.

Sample supply unit

A sample liquid-surface position measurement device includes: a first light source that illuminates a side face of a container containing a sample; a first optical measurement sensor that is located on the opposite side of the container from the first light source, and measures transmitted light from the first light source; a first label position measuring unit that measures a position of a label affixed to the container; and an analysis section that calculates a liquid-surface position or an interface position of the sample in the container, from transmitted-light intensity data in a longitudinal direction of the container which is measured by the first optical measurement sensor, and from the position of the label in the longitudinal direction of the container which is measured by the first label position measuring unit.

The type of blood collection tube () inserted into this system is automatically recognized, a lifting operation for checking the state and volume of analyte is switched on the basis of the automatic recognition result, a mechanical operation parameter based on the blood collection tube type is determined, and the blood collection tube () is grasped and lifted. Then, an image processing threshold is changed on the basis of the automatic recognition result, and image processing is performed using a threshold parameter based on the blood collection tube type to check the state and volume of the analyte. This enables precise automatic checking of the state and/or volume of the analyte for various types of blood collection tubes.
