Automated analysis device, and lid opening/closing mechanism
Provided is an automated analysis device equipped with a lid opening/closing mechanism with which it is possible to selectively open or close lids of a plurality of reagent containers, as well as to close all of the lids of the plurality of reagent containers, regardless of their current open/closed state. Each of a plurality of hooks 102 rotatably linked to a hook base part 104 has: a claw portion 203 which, when oriented to engage with a lid 101, causes force to act on the lid 101 in the opening direction; a basal part 202 which, when oriented to engage with the lid 101, causes force to act on the lid in the closing direction; and a closing protrusion 201 which, when oriented not to engage with the lid 101, causes force to act on the lid in the closing direction.
Reagent wells containing lyophilized reagents
System, apparatuses, and methods for performing automated reagent-based analysis are provided. Also provided are methods for automated attachment of a cap to a reaction receptacle, and automated removal of a cap from a capped reaction receptacle.
REAGENT CONTAINER RACK AND SPECIMEN ANALYZER
Disclosed is a reagent container rack used in a specimen analyzer configured to analyze a specimen by use of a reagent. The reagent container rack includes a holder configured to hold a reagent container that contains the reagent; and a lid configured to cover a mouth portion of the reagent container to form an airtight space between the lid and the mouth portion.
Automated analyzer
The purpose of the present invention is to stably hold the lid of a reagent container in an open state without being influenced by reagent container lid opening and closing operations. An automated analyzer is provided with reagent containers 116-118, a cassette 100, a reagent container lid opening and closing mechanism, and a lid holding mechanism 131. The reagent containers 116-118 accommodate the reagent and have lids 101a-101c that pivot about a pivot point. The reagent containers 116-118 are mounted on the cassette 100. The reagent container lid opening and closing mechanism opens and closes the lids 101a-101c. The lid holding mechanism 131 holds the lids 101a opened by the reagent container lid opening and closing mechanism.
Diagnostic assay strip cassette
A cassette removably holds assay strips. The cassette includes a cover and a base. The base includes a first face and a second face, the second face opposed across a thickness of the base from the first face. The base has at least a first channel in the first face that extends along at least a portion of the base, the at least first channel having a width, a length and a depth, at least the width and the depth of the first channel sized to at least partially receive an assay strip therein. The cover has a first face and a second face, the second face opposed across a thickness of the cover from the first face. The cover is releasably securable to the base in at least two orientations to alternatively expose a first set of markings and a second set of markings. The first and the second set of markings are carried by at least one of the cover or the base. The first set of markings is indicative of a first type of assay strip and the second set of markings is indicative of a second type of assay strip; the second set of markings being different from the first set of markings. The two different orientations include a first orientation in which the first face of the cover is exposed and the second face of the cover is adjacent one of the first or the second faces of the base, and a second orientation in which the second face of the cover is exposed and the first face of the cover is adjacent one of the first or the second faces of the base.
Sampling nozzle, automatic analyzer using the same, and method of manufacturing sampling nozzle
A CTS nozzle achieves the object of reducing rubber chips produced when the CTS nozzle is inserted into and extracted from a rubber plug of a sample container during dispensing of a sample, thereby inhibiting the wear of the tip of the CTS nozzle. The CTS nozzle has two cut surfaces at its tip, and the pressure applied from the rubber when the nozzle is inserted into the rubber plug is dispersed onto the two cut surfaces without being deflected onto one of the cut surfaces. The pressure applied to the nozzle due to the resilience of the rubber being pushed away by the nozzle is thus dispersed and the rubber chips produced by the friction between the cut surfaces of the nozzle and the rubber are reduced. As a result of the reduced friction, the wear of the tip of the nozzle is minimized.
System and method for incubation and reading of biological cultures
The present invention describes an integrated incubator and image capture module that regulates the incubator atmosphere and obtains high-resolution digital images of sample specimens. The incubator has a cabinet type enclosure that enables the provision of a controlled environment to the contents of the incubator by having at least three ports on one face of the cabinet for the passage of sample containers. Additionally, an image capture module is located immediately adjacent to the incubator. In this regard, using at least three separate access/egress points for the sample containers streamlines operation of the system and enhances preservation of the incubator environment. Furthermore, locating the image capture module directly adjacent to the incubator reduces the amount of time a sample container is exposed to the external environment, thereby reducing the extent to which samples are exposed to potential contaminants and reducing the exchange of the lab and ambient atmospheres.
Reagent well having a retention feature for retaining a lyophilized reagent
An article for performing a reaction includes a reagent well having a side wall, a bottom wall and an open upper end. A lyophilized reagent is retained within the well by a non-integral retention feature that is inserted into the open upper end of the well and fixed to a side wall above the reagent. An opening in the retention feature is smaller than the diameter of the reagent, but is sized to permit a pipette tip to be inserted into the well. The retention feature may be a collar fixed to the side wall and may include fingers extending axially into the well. The well and the retention feature may be correspondingly tapered. A method for reconstituting a lyophilized reagent includes the steps of drawing into a pipette tip attached to an automated pipettor an amount of a diluent and dispensing the diluent into the reagent well to thereby reconstitute the lyophilized reagent.
MANAGING SAMPLE EXPOSURE TO AIR ON AN AUTOMATION SYSTEM FOR PERFORMING CLINICAL LABORATORY IN-VITRO DIAGNOSTICS
A method for managing sample exposure to air on an automation system for performing clinical laboratory in-vitro diagnostics (IVD) includes receiving a sample in a capped container and loading the capped container onto a sample carrier. A plurality of test requests corresponding to the sample is received. Optionally, the capped container may be parked on a sample handler pending readiness of the system to process the test requests. Each test request is associated with one or more analytical modules included in an automated IVD system. In response to determining that the first analytical module is available to perform the first test request, the capped container is reloaded from the sample handler, if necessary, and decapped. Next the system performs prioritized delivery of the decapped container to the analytical modules in order to optimize performance of the assays with respect to the stability of the sample's analytes.
