Respiratory assemblies are disclosed that include first and second respiratory components and a latching mechanism. The latching mechanism is capable of engaging at least one retaining feature of a respiratory component, thereby impeding disengagement of the first respiratory component from the second respiratory component. Upon application of force to the actuator, the at least one latch is capable of disengaging from the retaining feature, thereby allowing disengagement of the first respiratory component from the second respiratory component. Respiratory components including or adapted to work with such latching mechanisms are also disclosed.

Respiratory assembly including latching mechanism

A system and method for preparing and analyzing samples. The system can include a sample preparation system and a sample detection system coupled to the sample preparation system. The sample preparation system can include a deformable self-supporting receptacle comprising a reservoir adapted to contain a liquid composition comprising a source and a diluent. The sample detection system can be positioned in fluid communication with the reservoir, and can be adapted to analyze a sample of the liquid composition for an analyte of interest. The system can further include a fluid path defined at least partially by the reservoir and the sample detection system. The method can include applying pressure to the deformable self-supporting receptacle to move a sample of the liquid composition in the fluid path to the sample detection system, and analyzing the sample for the analyte of interest with the sample detection system.

Sample preparation container and method

A system and method for preparing and delivering samples for analyte testing. The system can include a sample preparation system and a sample delivery system coupled to the sample preparation system. The sample preparation system can include a deformable self-supporting receptacle comprising a reservoir adapted to contain a liquid composition comprising a source and a diluent. The sample delivery system can include a valve positioned in fluid communication with the reservoir and adapted to control the removal of a sample from the sample preparation system. The method can include applying pressure to the deformable self-supporting receptacle to remove a sample from the sample preparation system via the sample delivery system.

A system and method for preparing samples to test an environmental surface for an analyte of interest. The system can include a deformable self-supporting receptacle comprising a reservoir, and a loaded substrate positioned in the reservoir of the deformable self-supporting receptacle. The loaded substrate can include a substrate and a source collected from the surface. The method can include combining the loaded substrate and a diluent in the reservoir, and agitating the loaded substrate and the diluent to form a liquid composition comprising the source and the diluent.
