  • Patent number: 9733265
    Abstract: Disclosed is a method for adjusting a position of an aspirator in a sample processing apparatus, the sample processing apparatus comprising the aspirator configured to aspirate a sample or a reagent from a container and a capacitance sensor connected to the aspirator to detect change in capacitance, the method comprising: moving the aspirator above a position adjustment part which is electrically conductive and which is disposed at a predetermined position; obtaining capacitance detected by the capacitance sensor while moving the aspirator; and setting reference position information indicating a reference position of the aspirator based on change in the obtained capacitance.

  • Patent number: 9618504
    Abstract: To provide a sample analyzer capable of accurately obtaining the number of analyzable samples. When analyzing a sample collected from a subject, a CPU of the sample analyzer calculates the number of analyzable samples based on a remaining number of tests of a reagent set in a reagent holding section and the number of tests of the reagent to be consumed in measurement of a control, and causes a output section to display the number of analyzable samples. When creating a calibration curve, the CPU calculates the number of analyzable samples based on a remaining number of tests of the reagent set in the reagent holding section, the number of tests of the reagent to be consumed in measurement of the control, and the number of tests of the reagent to be consumed in measurement of a calibrator, and causes the output section to display the number of analyzable samples.

  • Patent number: 9562920
    Abstract: Disclosed is an analyzer comprising: a liquid container mounting section in which a liquid container are set; a container mounting section in which at least one tip container accommodating a plurality of pipette tips is set; a cover detecting section that detects a presence of a cover mounted on the tip container; a dispensing section that equips a pipette tip accommodated in the tip container and dispenses a quantity of liquid from the liquid container to a reaction container via the equipped pipette tip; a detecting section that interrogate a property of the liquid; and a controller programmed to prohibit a process of equipping the pipette tip by the dispensing section when the cover on the tip container is detected, and permits the process when no cover is detected.

  • Publication number: 20120029934
    Abstract: A clinical sample analyzing system is disclosed. The system comprises a clinical sample analyzer installed in a facility of a user and a management apparatus which is able to perform data communication with the clinical sample analyzer and is installed in a facility different from the facility of the user. The clinical sample analyzer automatically transmits report data to the management apparatus when a predetermined event related to an initiation of a sample measurement occurs. The management apparatus outputs a notification when receiving the report data from the clinical sample analyzer. A clinical sample analyzer, a management apparatus and a method for managing a clinical sample analyzer are also disclosed.
