An analyzer that has a simple configuration, that is inexpensive, that can improve safety, and that can inhibit proliferation of microorganisms using ultraviolet light is realized. A first electric power switch, a second electric power switch, and a third electric power switch are connected in series between an ultraviolet LED that irradiates an interior of a shared reagent storage container with ultraviolet light and a power supply that supplies electric power to the ultraviolet LED. The first electric power switch, the second electric power switch, and the third electric power switch are configured with two contact points and a connection section that connects and disconnects the two contact points. The first electric power switch is opened when a reagent storage door is opened, and the second electric power switch is opened in response to an action of extracting an ultraviolet irradiation section from a shared reagent storage container. The third electric power switch is opened when an amount of the reagent within the shared reagent storage container is equal to or smaller than a constant value. When one of the first electric power switch, the second electric power switch, and the third electric power switch is opened, supply of the electric power to the ultraviolet LED is intercepted.

Managing reagent replacement and calibration/quality management processing for analysis devices is performed by a management device configured to manage analysis devices in a clinical laboratory having a cabinet storing a reagent used for measurement by analysis devices or a calibration/quality management sample. The management device includes a reagent detection unit configured to detect a timing to start reagent replacement preparation, based on a remaining amount of in-measurement reagents and a first preparation time required for replacing the reagent. Calibration/quality management processing preparation timing detection units are configured to detect a timing to start calibration/quality management processing preparation, based on the remaining amount of the in-measurement reagent. A notification person-in-charge determination unit notifies a laboratory technician of a request for the reagent replacement preparation or the calibration/quality management processing preparation upon receiving detection of a timing by the detection units.

A toilet for administering a product to a user is disclosed. The toilet includes a bowl, a mechanism for administering the product to the user, a storage structure for storing the product, a sensor that detects a property of the product, and a processor. The bowl is adapted to receiving excreta from the user. The processor compares the detected property with a range of values indicating the suitability of the product for being applied to a user. The processor generates an alert when the detected property falls outside the range of values.

Disclosed is a specimen analyzer configured to perform analysis on a specimen for a plurality of measurement items, the specimen analyzer including a measurement section configured to perform a specimen measurement for measuring a measurement sample prepared from a specimen and a reagent corresponding to a measurement item, and configured to perform a quality control measurement for measuring a measurement sample prepared from a quality control substance and a reagent corresponding to a measurement item; and a controller programmed to set a quality control for each measurement item, from a quality control group that includes at least two types of quality controls selected from a first quality control in which the quality control measurement is performed at a predetermined time, a second quality control in which the quality control measurement is performed every time the specimen measurement is performed a predetermined number of times of measurement, and a third quality control in which the quality control measurement is performed every predetermined time interval, the controller being programmed to control the measurement section in accordance with the set quality control.

The present invention is a sample processing apparatus. The apparatus includes: a sample processing unit configured to process a sample; a display; a memory for storing an electronic manual for the sample processing apparatus; and a controller that is capable of showing a relevant part of the electronic manual on the display when a trouble has occurred in the sample processing unit, the relevant part of the electronic manual describing an operation procedure to deal with the trouble.

A method of operating a tissue processor for processing tissue samples is provided. The tissue processor includes at least one retort for receiving tissue samples, at least one container for storing a reagent, and at least one sensor arranged for fluid communication with one or both of the at least one container and the at least one retort for measuring a measured purity level of a reagent. The method includes the steps of conducting reagent from the at least one container or the at least one retort to the at least one sensor, automatically measuring, by means of the at least one sensor, a measured purity level of the reagent, checking whether the measured purity level meets a predetermined purity level of the reagent associated with the at least one container, and automatically determining, based on a result of checking, whether the reagent is suitable for processing tissue samples in the tissue processor. A tissue processor for processing tissue samples is also provided. A container is also provided for storing tissue samples for processing in a tissue processor.

Provided is an automatic analysis device in which a step for checking the progress of deterioration of a reagent can be automated and the expiration date of the reagent can be managed. Properties in absorption spectroscopic analysis pertaining to a standard liquid during implementation of calibration are used to calibrate the automatic analysis device so as to generate a standard curve N times for each lot. A series of action are repeated, with successive results in the implementation of calibration being updated while N is increased by 1 for each instance, until a first lot is completed. The final results are displayed in a dedicated screen image. This makes it possible to preliminarily ascertain the deterioration of the reagent, therefore making it possible to preemptively prevent inferiority in terms of repeatability and linearity, as well as to contribute to freedom from complex operations, reduction of cost, improvement in quality of data, and prevention of medical malpractice caused by a delay in reporting.

The method for generating an index for managing the analytical accuracy of a sample analyzer includes a step of acquiring a determination result related to whether a sample is positive or negative from a plurality of sample analyzers, and a step of generating an index based on a ratio of a sample determined to be positive or negative by the plurality of sample analyzers from a plurality of determination results obtained from the plurality of sample analyzers.

To provide an automatic analyzer capable of relaxing the effect of a previously created mixed liquid when a new mixed liquid is created. An automatic analyzer according to the present disclosure: is configured so as to create a second mixed liquid after a first mixed liquid is created; and introduces a relaxation reagent to relax the effect of a first reagent remaining in a mixed liquid chamber when the second mixed liquid is created into the mixed liquid chamber on the basis of characteristics of the first mixed liquid.

Provided is an automatic analysis device capable of replenishing consumables without loss of a specimen and without stopping analysis. The state of an automatic analysis device 100 includes a replenishment prohibition state in which replenishment of consumables (reaction vessel 8, specimen dispensing tip 10a and external reagent vessels 21a, 21b, 21c) is prohibited, and a replenishment permission state in which replenishment of consumables is permitted. In the replenishment prohibition state, a specimen dispensing mechanism 10 performs dispensing, and detection units 18a and 18b perform analysis. In the replenishment permission state, the specimen dispensing mechanism 10 does not perform dispensing, and the detection units 18a and 18b perform analysis. A device state control unit 119d causes the automatic analysis device 100 to transition to the replenishment permission state when the remaining amount or the remaining number of the consumables predicted by a consumables remaining amount prediction unit 119b becomes equal to or less than a predetermined value.
