The purpose of the present invention is to provide a control system which, when a sensor is not built in a motor, saves the power of the sensor and increases the life thereof by on/off-controlling power supply to the sensor before and after the operation of the motor, and also to provide an automatic analysis device. The control system 201 is provided with sensors 309a, 309b, 602, 603 for monitoring the operation of a motor and a control mechanism for controlling the operation of the motor. The control mechanism is provided with: a function of starting power supply to the sensors 309a, 309b, 602, 603 before a first predetermined time from the time when the motor starts the rotating operation; and a function of stopping the power supply to the sensors 309a, 309b, 602, 603 after a second predetermined time from the time when the motor terminates the rotating operation.

A pretreating apparatus includes a transferring mechanism configured to transfer a storing container storing an unpretreated sample or a pretreated sample, a pretreating portion having a port in which the storing container storing the sample is installed by the transferring mechanism, configured to pretreat the sample in the storing container installed in the port, and a diluting portion configured to suck a predetermined amount of the pretreated sample from the storing container and supply the sample and a diluent to an empty storing container to dilute the sample.

An excrement detecting disc and a manufacturing method thereof are disclosed. An excrement detecting reagent block and a control reagent block are pasted on fan-shaped blades with spoke-like arrangement on the detecting disc to accommodate more detection items. The spaces are located between the blades to avoid the detection items interfering with each other. The widths and shapes of the blades are changed, and the personalized detection items and the general detection items coexist in the detecting disc. Various types of detection items are collected. A negative control is set for each detection item to improve the reliability of the detection results.

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.

A sample processing arrangement for processing a fluidic sample, the sample processing arrangement including a sample holder for accommodating the fluidic sample, an apparatus having a rotor mechanism and being configured for selectively operating the sample holder in an orbital motion mode for sample mixing, particularly for shaking, or in a rotary motion mode for sample separation, particularly for centrifuging, a mounting platform having a central portion on which the apparatus and the sample holder are mounted and having a surrounding portion circumferentially surrounding the central portion, and a plurality of module accommodation positions circumferentially distributed in the surrounding portion to surround the rotor mechanism and the sample holder, wherein each of the module accommodation positions is configured for detachably accommodating a selectable one of a plurality of sample processing modules, each being configured for fulfilling an assigned sample processing task, by accommodating the respective sample processing module in the respective one of the module accommodation positions.

An apparatus for processing a biological sample for optical analysis having a cartridge with a sample supply container and a couvette, a cartridge/magazine holding the cartridge, and a cassette fan positioned over the cartridge. A filter cassette is mounted within the cassette fan, wherein the filter cassette has an inlet for receiving a sample from the sample supply container, an outlet for discharging the filter sample into the couvette, and valves therein to manipulate the sample for filtering. A cassette clamp is positioned over the filter cassette to secure the cassette and operate the filter cassette. A method for implementing this apparatus is also described herein. Additionally an apparatus is used for and a method measures waste fluid that passes over a filter element to control the amount of rinse fluid passing over the filter element.

A method and apparatus for processing a sample is presented. The apparatus comprises a chamber, a first input for inputting a first vessel into the chamber, a second input for inputting a second vessel into the chamber, the second input is different from the first input, a rotor comprising a first compartment for receiving the first vessel and a second compartment for receiving the second vessel, a gripper to grip the first vessel and to transport the first vessel to the first compartment, and a pipettor to pipette a sample from the first vessel and/or second vessel. The rotor rotates between a first position where the first vessel is transportable to the first compartment by the gripper, a second position where the second vessel is loadable into the second compartment, and a third position where the sample of the first vessel and/or second vessel is aspiratable by the pipettor.

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.

An automatic analyzer provided with a probe provided with an opening end for discharging a dispensing liquid, a pump connected to a side opposite to the opening end of the probe, and a dispensing mechanism provided with a drive control unit which controls drive of the pump, in which the drive control unit controls the drive of the pump to realize a discharging speed at which a droplet of the dispensing liquid is formed at the opening end of the probe at an initial stage of discharge drive and a discharging speed at which a liquid column of the dispensing liquid is formed at the opening end of the probe at a later stage of the discharge drive at the time of the discharge drive of the pump to discharge a predetermined amount of dispensing liquid into a dispensing container from the opening end of the probe.

The presently disclosed subject matter relates to methods for rapid, sensitive, and high-throughput nucleic acid testing of biological samples, e.g., blood, serum, or plasma samples from donors, as well as systems capable of performing such high-throughput nucleic acid testing.
