A system for automated microorganism identification and antibiotic susceptibility testing comprising a reagent cartridge, a reagent stage, a cassette, a cassette, stage, a pipettor assembly, an optical detection system, and a controller is disclosed. The system is designed to dynamically adjust motor idle torque to control heat load and employs a fast focus process for determining the true focus position of an individual microorganism. The system also may quantify the relative abundance of viable microorganisms in a sample using dynamic dilution, and facilitate growth of microorganisms in customized media for rapid, accurate antimicrobial susceptibility testing.

An automated analyzer capable of continuously performing supply of consumables is realized while continuing measurement is performed, by a simple and small amount of mechanism. An automated analyzer includes a unit that executes processing necessary for sample analysis; a consumable supply unit that supplies consumables necessary for the sample analysis to the unit; and a control device that controls operations of the unit and the consumable supply unit, in which the consumable supply unit includes a consumable container holding portion that holds a consumable storage container in which consumables is aligned and accommodated, a preliminary storage portion that temporarily holds the consumables taken out from the consumable storage container, and a transport mechanism that transports the consumables to the unit, and in which the control device transports and stores at least a portion of the consumables taken out from the consumable storage container in the preliminary storage portion.

Provided is an automatic analyzer that can perform a reagent preparation/disposal operation comfortably and smoothly as when printing a reagent list such as a reagent preparation/disposal list on paper even without printing the reagent list. The automatic analyzer that performs analysis using a sample and a reagent, the automatic analyzer including: a storage unit that stores reagent information related to a reagent remaining amount or a reagent expiration date of each of reagent containers; and a display unit that displays a reagent list in which reminder information that gives a reminder to an operator is assigned to each of setting positions of the reagent containers based on the reagent information stored in the storage unit. The reagent managing unit updates display of the reagent list such that a reagent container selected by the operator is visually identifiable while the reagent list is displayed.

An automatic analysis device has a plurality of types of photometers having different quantitative ranges, and an analysis control unit for quantifying the desired component in specimens based on measurement values of one or more photometers selected from among the plurality of types of photometers. The analysis control unit: sets a switching region in an overlap region of respective quantitative ranges of the plurality of types of photometers, said switching region having a greater width than does the variation in quantitative values of the desired component based on the measurement values of photometers having the same specimen; compares the quantitative value of a quantitative range portion that corresponds to the switching region and the quantitative values of the desired component based on the measurement values of the photometers; and selects a photometer to be used in quantitative output of the desired component from among the plurality of types of photometers.

A diagnostic analyzer includes a rotating device, a first optical reader, and a second optical reader. The rotating device includes a first darkened compartment, a second darkened compartment, and an optical path along which the first darkened compartment and the second darkened compartment travel. The first optical reader is operable to read the first darkened compartment and the second optical reader is operable to read the second darkened compartment.

A matrix droplet extruder includes a casing; one or a plurality of reagent containers; a plurality of pneumatic connectors on the casing that are each configured to be connected to a pneumatic actuator to provide controlled pneumatic pressure to one or more of said plurality of the pneumatic connectors; a droplet matrix extrusion surface with one or a plurality of printing zones, each printing zone comprising an array of perforations; and a liquid management chip for dispensing one or more reagents from said one or a plurality of reagent containers through the array of perforations of said one or a plurality of printing zones, so as to repeatedly generate a matrix of droplets when applying the pneumatic pressure to said one or more reagents.

A reagent-bottle lid opening mechanism is disclosed, which has a needle for piercing a lid of a reagent bottle to be delivered to a reagent disk, has an aligning mechanism of automatically adjusting a position of the needle with respect to the lid such that a needle body of the needle can stick in the center of the lid, and accurately and repeatedly makes an incision in the center of the lid. As a result, an automatic analyzer is provided that is capable of unsealing the center of the lid of the reagent bottle with accuracy even if the central axis of the needle and the central axis of the lid are offset from each other.

The present invention relates to a three-degree-of-freedom library preparation cassette and a method using the same. Two-degree-of-freedom movement capability is provided for mutual positioning between a pipette and reagent wells, within a limited small volume, by combining rotation of a mixing reagent tray and relative horizontal movement between the pipette and the mixing reagent tray, thus greatly increasing the number of reagent wells that can be provided, thereby increasing the functions and applications of the whole system; and the device is simple in structure, low in cost, and suitable for disposable use.
