A fluid collection system comprises a sealed reagent container that fits inside a sample container and is unsealed by disengaging a seal comprised in a sample container. The sealed reagent container contains a reagent, such as a nucleic acid preservative. The reagent container also includes a sleeve disposed opposite the sealed opening. The sleeve includes a distal opening for receiving a sample and a proximal opening disposed in the sample container for guiding a sample from the distal opening and through the proximal opening into the sample container. Disengaging the seal releases the reagent into the sample container with the sample, where they mix.

A cover for a fluid container having an essentially plane cover plate for closing at least one opening of at least one fluid container and at least two ports, and each port has a through channel extending through the entire thickness of the cover plate and a fluid impermeable first membrane is arranged over the entire cross section of the through channel of the first port and an at least gas permeable second membrane is arranged over the entire cross section of the through channel of the second port is disclosed.

A reaction processor includes: a reaction processing vessel including a channel in which a sample moves and a pair of air communication ports, a first air communication port and a second air communication port, provided at respective ends of the channel; a temperature control system that provides a medium temperature region and a high temperature region between the first air communication port and the second air communication port in the channel; and a liquid feeding system that discharges and sucks air in order to move and stop the sample inside the channel. One of the pair of air communication ports of the reaction processing vessel that is farther away from the high temperature region communicates with the liquid feeding system via a tube. One of the pair of air communication ports of the reaction processing vessel that is closer to the high temperature region is opened to atmospheric pressure.

A specimen holder includes a stick and an RFID tag. The stick is elongate along a longitudinal direction, and has a distal end and a proximal end opposite the distal end with respect to the longitudinal direction. The stick includes an outer surface and a distal portion of the outer surface that is closer to the distal end than the proximal end. The stick further includes an internal cavity that extends from a first terminal end to a second terminal end. The stick includes a midplane that is normal to the longitudinal direction, and the midplane is located equidistant between the distal end and the proximal end. The first terminal end, the second terminal end and an entirety of the internal cavity are all located between the midplane and the proximal end. The RFID tag is positioned within the internal cavity.

A biological sample collection system includes: a sample collection vessel having a sample collection chamber for receiving a biological sample; a sealing cap including a reagent chamber for storing a sample preservation reagent and being configured to associate with the sample collection vessel; and a selectively movable valve at least partially disposed within the sealing cap. The selectively movable valve includes a post with an interior chamber and fluid vent and a valve head associated with a distal portion of the post that initially occludes the fluid vent when the valve is in the closed configuration. Associating the sealing cap with the sample collection vessel causes a physical rearrangement of the post and the valve head in order for the fluid vent to become unoccluded by the valve head, thereby placing the valve in an open configuration and allowing fluid communication between the reagent chamber and the sample collection vessel.

A sampling structure, a sealing structure and a detection assembly are provided. The sampling structure includes a first main body, a second main body and a third main body. The first main body includes a first channel, the first channel includes a first opening that is exposed. The second main body is connected to the first main body and includes a second channel and at least one partition column located in the second channel, the second channel is linked with the first channel, and a first gap is between the partition column and a channel wall of the second channel. The third main body is connected to the second main body and includes a chamber, the chamber is linked with the second channel and is capable of containing a sample.

The invention provides devices that improve tests for detecting specific cellular, viral, and molecular targets in clinical, industrial, or environmental samples. The invention permits efficient detection of individual microscopic targets at low magnification for highly sensitive testing. The invention does not require washing steps and thus allows sensitive and specific detection while simplifying manual operation and lowering costs and complexity in automated operation. In short, the invention provides devices that can deliver rapid, accurate, and quantitative, easy-to-use, and cost-effective tests.

Described herein are various inventions and embodiments thereof, directed to systems, devices, and methods for separating a sample. Embodiments of sample collection devices disclosed herein may maintain separation of different volumes of sample during collecting, handling, and accessing of the sample. A sample collection device, in some embodiments, may comprise an enclosure defining a first chamber, a second chamber, and a partition therebetween configured to separate the first chamber and the second chamber. An assembly coupled to the partition may be configured to transition between an open configuration and a closed configuration based on fluid and gas flow through the assembly.

A cartridge of the present invention is to be used in combination with a channel chip including a channel through which a liquid flows. The cartridge includes a reservoir for storing a liquid, in which a through hole configured to be connected to the channel is opened into a bottom part of the reservoir; a liquid discarding part for discarding the liquid in the reservoir; and a connection part which is disposed above the through hole, and connects the reservoir and the liquid discarding part to each other.
