A detection chip, a method for using a dejection chip, and a detection device are provided. The detection chip includes a chip substrate and a first sealing film that are stacked. The chip substrate includes a first surface, and the first sealing film covers the first surface of the chip substrate The chip substrate further includes a fluid channel on the first surface, and the fluid channel includes a plurality of membrane valve portions. The membrane valve portions are configured to allow a portion of fee first sealing film covering the membrane valve portions to approach and separate, so as to close and open the fluid channel correspondingly.

Disclosed herein are cell processing systems, devices, and methods thereof. A system for cell processing may comprise a plurality of instruments each independently configured to perform one or more cell processing operations upon a cartridge, and a robot capable of moving the cartridge between each of the plurality of instruments.

According to one embodiment, a standard sample container includes a soft container, a discharging mechanism, and a chamber. The soft container is adapted to contain a standard sample for use in preparing a calibration curve or managing accuracy for an automatic analyzer. The discharging mechanism is adapted to discharge the standard sample present in the soft container into a reaction container via a dispensing nozzle. The chamber is adapted to accommodate the soft container.

A vented dual port centrifuge tube includes a tubular receptacle having upper and lower ends. A first common inlet and outlet port is formed in the upper end and a second common inlet and outlet port is formed in the lower end. A piston is sealably and slidably mounted within a chamber of the receptacle. A vent is supported in the upper end of the receptacle and a flexible vent pipe attached to the piston is communicably interconnected between the vent and a lower region of the chamber between the piston and the lower end of the receptacle. Air pressure in the lower region of the receptacle is equalized or neutralized as biological fluids and separated constituent components are introduced into and aspirated from the receptacle through the common inlet ports.

The present application is generally directed to systems, methods, and devices for diagnostics for sensing and/or identifying pathogens, genomic materials, proteins, and/or other small molecules or biomarkers, for example, using loop-mediated isothermal amplification (LAMP). Some implementations include additional improvements, such as improvements to sample and reagent mixing, sample deposition, and compensation of inhibitors in the sample. Also disclosed herein are nucleic acid primers for use in the sensitive and specific detection of pathogens in biological samples by LAMP, which may be performed in the devices disclosed herein. The biological samples may be derived from patients including humans, plants, food, soil, contaminated surfaces, or animals such as livestock.

A point-of-care testing (POCT) system comprising an analyzer, a measurement cartridge, and a calibration cartridge for calibrating the measurement cartridge is described. The measurement cartridge comprises at least one electrochemical sensor for measuring the one or more properties of the blood sample, and the calibration cartridge comprises a similar at least one electrochemical sensor and at least one sealed blister containing calibration fluid for calibrating the measurement cartridge. Examples of properties of the blood sample may be pH, blood gases, electrolytes, and metabolites like glucose and creatinine. The measurement cartridge may also comprise an optical chamber for measuring for example, bilirubin and hemoglobin species, for which the analyzer comprises stored calibration algorithms. The optical chamber may be disposed in any location in the measurement cartridge, for receiving a portion of the blood sample.

Cradles for draining liquid from containers are described herein. An example apparatus includes a housing having a bottom wall, a side wall and an open top. The housing is to receive a container having liquid. The example apparatus includes a probe extending upward from the bottom wall toward the open top and is to drain the liquid from the container when the probe is inserted into the container. The example apparatus also includes a sliding lock slidably disposed within the housing that receives a cap or top of the container when the container is inserted into the housing. The sliding lock includes a key slot. The sliding lock is movable when a cap or top of the container has a matching key that engages the key slot, which enables the sliding lock to move downward to expose the probe and drain the liquid from the container.

The disclosure relates to devices, solutions and methods for collecting and processing samples of bodily fluids containing cells (as well as embodiments for the collection, and processing and/or analysis of other fluids including toxic and/or hazardous substances/fluids). In addition, the disclosure relates generally to function genomic studies and to the isolation and preservation of cells from saliva and other bodily fluids (e.g., urine), for cellular analysis. With respect to devices for collection of bodily fluids, some embodiments include two mating bodies, a cap and a tube (for example), where, in some embodiments, the cap includes a closed interior space for holding a sample preservative solution and mates with the tube to constitute the (closed) sample collection device. Upon mating, the preservation solution flows into the closed interior space to preserve cells in the bodily fluid. The tube is configured to receive a donor sample of bodily fluid (e.g., saliva, urine), which can then be subjected to processing to extract a plurality of cells. The plurality of cells can be further processed to isolate one and/or another cell type therefrom. The plurality of cells, as well as the isolated cell type(s), can be analyzed for functional genomic and epigenetic studies, as well as biomarker discovery.
