A spraying device for spraying fluid from a replaceable refill is described wherein the refill possesses a refill body containing a reservoir of fluid to be sprayed, a valve stem in fluid communication with the reservoir and a spray head mounted on the valve stem, the spray head having an exit nozzle, wherein the spray device comprises: a housing formed from an top portion and a base portion which are releasably connectable with each other through contact between engagement means on each portion, wherein the top portion comprises: a cavity configured to house at least an top portion of the refill therein; a top surface and an engagement surface having an top portion housing wall therebetween, wherein the top portion housing wall has a thickness; an actuation mechanism configured, in use, to actuate the spray head to spray fluid via the exit nozzle; a spray opening configured to permit, in use, sprayed fluid to exit the device into the surrounding environment; and wherein the base portion comprises: a cavity configured to house at least a base portion of the refill therein said cavity being defined by a cavity wall and a support platform configured, in use, to support the refill at a predefined position in the cavity; the base portion being provided with an engagement surface and a bottom surface and a base portion housing wall therebetween; wherein the base portion housing wall at least adjacent the bottom surface is spaced apart from the cavity wall by at least the predefined top housing wall thickness to define a top portion receiving channel; and whereby the device facilitates an operational configuration wherein the top portion and the base portion of the housing are engaged with each other by their respective engagement means with the refill located within the respective cavities; and wherein the device facilitates a packaged configuration wherein at least the engagement means and at least a some of the top portion housing wall of the top portion are located within the top portion receiving channel.

A system and method for periodically releasing oxygen rich gas for inhalation by a user. A container is filled, at least in part, with oxygen gas. The container has a release valve that can be used to selectively release some of the oxygen gas from the container. An activation unit is provided that is connected to the container. The activation unit operates the release valve at a selected rate. Each periodic pulse contains a volume of the oxygen gas released over a first period of time. The first period of time is preferably no longer than the time it takes a user to take a breath. The periodic pulses are spaced to correspond to the rate of respiration or some multiple thereof. A dispenser is provided that directs the oxygen gas into a place where it can be inhaled.

A system includes processing circuitry and a drone. The drone includes a dispenser subassembly that includes a housing comprising an aerosol dispensing system and configured to receive a syringe such that an applicator of the syringe is positioned distally from the housing; a trigger that is positioned in contact with a nozzle of the aerosol dispensing system; an actuator arm; and an actuator motor configured to move the actuator arm in a reciprocating motion. Control logic of the drone is configured to navigate, based on navigation instructions received from the processing circuitry, the drone to an area associated with an object of potential survey interest (OoPSI) such that the applicator of the syringe or the nozzle of the aerosol dispensing system is proximate to the area associated with the OoPSI.
