Automated method and system for obtaining and preparing microorganism sample for both identification and antibiotic susceptibility tests
A method and automated apparatus for locating and selecting a colony of microorganisms on a culture dish and subjecting the obtained sample to a plurality of downstream tests including a test to identify the microorganism and a test to identify the susceptibility of the microorganism to antibiotics. The method includes the automated steps of locating and selecting a colony of microorganisms on a culture dish; obtaining a sample of the selected colony of microorganisms; preparing a suspension of a sample of microorganisms automatically by submerging the pick tool with the sample in a suspension, after which the pick tool is vibrated in at least the vertical direction to release the sample from the pick tool in the suspension. The turbidity of the suspension is monitored to ensure that the concentration of microorganism in suspension is sufficient so that the suspension is used a source for sample for both identification and antibiotic susceptibility of the microorganisms in the sample. The apparatus and system optionally provides for downstream processing of samples prepared for antibiotic susceptibility testing (AST). Such apparatus includes further processing after inoculation of an AST panel for the AST test. Such further processing includes capping and transferring inoculated panels to AST instrument.
SLIDE INVENTORY AND REINSERTION SYSTEM
A slide rack inventory and reinsertion system for use with a digital slide scanning apparatus is provided that determines, prior to scanning of glass slides in a slide rack, a status of each slot in the slide rack as properly occupied, improperly occupied, or empty. The system also determines whether a slide that has been removed from the slide rack for processing has been properly reinserted into the slide rack.
LOAD LOCK CHAMBER ASSEMBLIES FOR SAMPLE ANALYSIS SYSTEMS AND RELATED MASS SPECTROMETER SYSTEMS AND METHODS
Load lock assemblies for a sample analysis system, such as a mass spectrometry system, include a load lock chamber having longitudinally opposing first and second end portions and a through channel, a door coupled to the second end portion, and a seal assembly coupled to the first end portion. The seal assembly includes a rigid seal housing member coupled to a housing of the load lock chamber. The rigid seal housing member includes a port forming part of the first end portion of the through channel of the load lock chamber. The rigid seal housing member can include a self-centering cartridge and/or a flexure member coupled to the housing of the load lock chamber. Where used, the flexure member has an outer perimeter that extends above and below the rigid seal housing member and includes an aperture that is aligned with the port of the rigid seal housing member.
Fixed reference edge system for slide loading and unloading
A fixed reference edge system that guides a glass slide from a slot of a slide rack onto a scanning stage and guides the glass slide from the scanning stage into the slot of the slide rack. In an embodiment, the fixed reference edge has a first side that is parallel to a side of the slot of the slide rack. The system comprises an assembly that includes a push bar configured to push the slide from the slot onto the scanning stage, and a pull bar configured to pull the slide from the scanning stage into the slot of the slide rack. When the slide is pulled into the slide rack, the long edge of the slide is pressed against the first side of the fixed reference edge to maintain a parallel orientation between the slide and the slot of the slide rack.
Physiological signal monitoring device
A physiological signal monitoring device is adapted for monitoring a physiological signal of a biofluid, and includes: a biosensor strip that has at least one signal output end adapted for outputting the physiological signal; a strip reciprocating module that includes a strip seat for receiving the biosensor strip, a guide seat mounted to the strip seat, and a rotating plate mounted rotatably to the strip seat for triggering reciprocating movement of the biosensor strip and the guide seat relative to the strip seat; and a contact module that includes an electronic module, and at least one extending piece connected electrically with the at least one signal output end to transmit the physiological signal to the electronic module.
Cartridge positioning system
A system for positioning a cartridge is disclosed. The system has a drive rod with a body having a first axis and a groove formed in the body. The groove has a first portion that is not perpendicular to the first axis and a second portion that is perpendicular to the first axis. The system also includes a collar that coupled to the drive rod. The collar has an element configured to engage the groove. Rotation of the drive rod with respect to the collar while the element is engaged in the first portion of the thread causes the collar to move with respect to the first axis. Rotation of the drive rod with respect to the collar while the element is engaged with the second portion of the thread causes the collar to remain stationary with respect to the first axis.
System for handling slides
The present disclosure provides a system for handling slides. The system includes a carrier having a linear engagement feature and a notch, a cartridge having a compartment configured to accept the carrier, and a cartridge positioning system with a platform configured to accept the cartridge and an actuator. The actuator has a rotary engagement feature configured to engage the linear engagement feature and a tab configured to interact with the notch when the carrier is accepted into the compartment and the cartridge is accepted onto the platform.
Systems and methods for automated preparation of biological specimens
An automated system for processing a sample contained in a liquid sample container includes an automated tool head configured to rotate about a first axis, and to translate along a second axis different than the first axis, an analytic element positioner having an analytic element holder configured to releasably grip an analytic element, and a specimen transfer device carried by the tool head, wherein the tool head is configured to automatically position a working end of the specimen transfer device to obtain a specimen from a sample container held in the sample container holder, and to transfer the obtained specimen to an analytic element held by the analytic element holder, respectively, through one or both of rotation of the tool head about the first axis and translation of the tool head along the second axis.
Automated high volume slide processing system
An automated system is provided for performing slide processing operations on slides bearing biological samples. In one embodiment, the disclosed system includes a slide tray holding a plurality of slides in a substantially horizontal position and a workstation that receives the slide tray. In a particular embodiment, a workstation delivers a reagent to slide surfaces without substantial transfer of reagent (and reagent borne contaminants such as dislodged cells) from one slide to another. A method for automated processing of slides also is provided.
Automated substrate loading
This disclosure is directed to system for transferring a substrate, such as a microscope slide, and holding the substrate within at least one device. The system includes a holder for holding the substrate and a gripper for transferring the substrate, such as between a cassette or stack and the holder. A method is also discussed herein.
