Headgear for mounting a mask on the head of a user, comprising a headgear strap; and an elongate strap guide comprising a forward portion mounted on the mask, and a rearward portion distal from the mask. The headgear strap is coupled, for example via a movable carriage or loop, to the elongate strap guide so that a forward portion of the headgear strap is movable along the elongate strap guide between the forward and rearward portions. The elongate strap guide may be relatively rigid, and may comprise an elongate rail. The headgear may connect to the mask to form a continuous loop, the headgear strap being coupled to the elongate strap guide such that the length of the continuous loop can be increased without adjusting a length of the headgear strap, to doff the mask. The headgear may be adjusted without disconnecting the headgear from the mask.

A device for blocking the nasal airway at the opening of the nostrils has two tubes that terminate at distal tips. The tubes are each separated into channels, or lumens, running the length of the tubes, including an outer lumen that extends from an inflation connection port to an inflatable donut just below the distal tip of each tube. With the distal tips received in the respective left and right nostrils of the user, the donuts are inflated to close off the nostrils at the rim, adjacent the nasal vestibule. Filters may be provided between the inflation ports and the distal tips for cleaning air prior to entry into the nasal cavity. The device may further include left and right ear straps to secure the device on the user's ears.

A flow through photochemistry apparatus and methods of use are disclosed in the present application. One or more reactant materials are passed through a reaction chamber and are exposed to electromagnetic radiation. The reaction chamber has reflective walls arranged to reflect electromagnetic radiation across the volume of the chamber a plurality of times, thereby increasing the probability of the electromagnetic radiation interacting with the reactive materials. The reaction chamber may be used for sterilization and photochemistry applications.
