摘要:
The present invention relates to a system for conducting the identification and quantification of micro-organisms, e.g., bacteria in biological samples. More particularly, the invention relates to a system comprising a disposable cartridge and an optical cup or cuvette having a tapered surface; an optics system including an optical reader and a thermal controller; an optical analyzer; a cooling system; and an improved spectrometer. The system may utilize the disposable cartridge in the sample processor and the optical cup or cuvette in the optical analyzer.

Disclosed is a station, for testing an analyte in a sample, enabling accurate and quick reaction and analysis of the sample and a reagent in one apparatus. To this end, the present disclosure provides a station, which is for testing a sample by means of inserting a cuvette, having a standby chamber on which a collecting member is placed, a sample chamber, a reagent chamber and a detection unit. The station comprises: a housing which has an input/output part into which a cuvette is inserted; a driving unit which is provided inside the housing, horizontally moves the cuvette, vertically moves a collecting member, reacts a sample in a sample chamber and a reagent in a reagent chamber, and injects a reaction result thereof into a detection unit; and an optical reader which is provided on the horizontal movement path of the cuvette and is for analyzing the reaction result.

A method of determining a presence of target molecules in a body fluid (16) with cells comprises the steps of: lysing cells in the body fluid (16) for generating a lysate (17); mixing the lysate (16) with particles (36) with first detector molecules; binding target molecule to the particles through first detector molecules; exposing a substrate (38) with second detector molecules to the lysate (17); binding target molecules to the substrate through second detector molecules; detecting particles (36) attached to the substrate (36).

A rotating holder is envisioned to invert Petri dishes by 180° and to loosen the bottom from the cover, which has two positions to accommodate Petri dishes. By inverting the rotating holder around a rotation axis, the Petri dishes are reversed and inverted in the two positions. Thus the bottom of the upper Petri dish will be lowered and be engaged by a gripper.

A diagnostic analyzer includes a track, a light-blocking member, a motor, and an optical testing device. The track moves a reaction vessel held by the track. The light-blocking member is disposed adjacent to the track. The light-blocking member moves from a first position apart from the track to a second position closer to the track. When the light-blocking member is disposed in the first position a sample contained within the reaction vessel held by the track is exposed to light. When the light-blocking member is disposed in the second position the sample contained within the reaction vessel held by the track is blocked from exposure to the light. The motor moves the light-blocking member between the first and the second positions. The optical testing device is disposed adjacent to the track for optically testing the sample contained within the reaction vessel held by the track when the at least one light-blocking member is disposed in the second position.
摘要:
An indicator for enabling an analytical instrument to positively detect the presence of a vial in respective vial-receiving rack position regardless of whether the vial is oriented in a manner necessary for a code reader to read a code printed on the vial. Translation of a leaf spring upon insertion of a vial into a rack position causes a flag to obscure a code provided adjacent the rack position. An instrument into which the rack is installed interprets the failure of the code reader to detect this code as positive indication that a vial is disposed within the respective rack position.

An Interactive Transparent Individual Cells Biochip Processor (ITICBP) device is described, which is useful for assessing a single, individual living cell at identifiable location or assessing group of cells each at identifiable location.

An analyzer system for automatic column chromatography, and method for its use, includes an array of chromatograph columns and multi-cell cuvettes associated with each column. Chromatographic separation takes place under a constant, low fluid pressure. A pressure system distributes air to each column during chromatographic separation but prevents leakage of air if the column array is partially empty. The multi-cell cuvette collects and separates the eluates associated with a single column. The system provides for automatic removal of caps from the bottoms of the chromatograph columns and provides for automatic optical density reading.
摘要:
Introduced here are diagnostic systems that are able to autonomously move to a desired location within a healthcare environment. As such, a diagnostic system may allow an operator to conduct a biochemical test on site. A diagnostic system may include (i) a cartridge in which a patient sample can be deposited, (ii) a robotic cart in which the cartridge can be inserted for analysis, and (iii) a control platform that is responsible for managing movement of the robotic cart throughout its physical environment. In addition to having the components needed to analyze the sample deposited into the cartridge, the robotic cart could also include storage for “used” or “unused” cartridges. Thus, the robotic cart may not only be able to perform analysis of the sample on site, but the robotic cart may also be able to transport all of the supplies needed to obtain the sample to the operator.
