Abstract: A respiratory assistance apparatus has a gases inlet configured to receive a supply of gases, a blower unit configured to generate a pressurised gases stream from the supply of gases; a humidification unit configured to heat and humidify the pressurised gases stream; and a gases outlet for the heated and humidified gases stream. A flow path for the gases stream extends through the respiratory device from the gases inlet through the blower unit and humidification unit to the gases outlet. A sensor assembly is provided in the flow path before the humidification unit. The sensor assembly has an ultrasound gas composition sensor system for sensing one or more gas concentrations within the gases stream.

Abstract: An apparatus is provided for trapping animals, a carrier for use with same, and a method of trapping animals using same. The apparatus includes a reservoir for animal bait, a tubular housing for the reservoir where the housing has a lower end having an opening and the lower end is configured with a stop located on its outer circumference proximate to the opening of the housing, a plurality of resilient loops, a release mechanism for the loops, and carriers for each loop, where each carrier is configured to be slidably moveable about the outer circumference of the housing when the housing is in a substantially vertical orientation, and wherein the release mechanism is configured to be activated to move the loop from its carrier onto the body of an animal activating the release mechanism.
