Abstract: A nasal breathing aid comprising the following components: a housing; facial engagement means attached thereto; at least two nostril pieces coupled to the housing. On the housing, there are at least two nasal inlets; at least one vent; and in the housing: a first passage and a second passage, each communicating an inlet with a vent, and fluid-isolated from each other, and restriction means configured to allow free flow of air through each passage from a vent to an inlet, and flow of air through the first passage independently restricted from flow of air through the second passage, from an inlet to a vent.

Abstract: An inserter for inserting a needle of a drug delivery device through the skin of a user, the inserter having an inserter housing (30); a base section (60) associated with the inserter housing such that an interaction between the inserter housing and the base allows the inserter housing to tilt in relation to the base; a manually displaceable plunger (20) deployed in the housing, the plunger displaceable between a stand-by position and an insertion position; and an insertion needle (6) extending from the plunger in an insertion direction; wherein the manual displacement of the plunger is achieved by applying a force greater than a required force threshold so as to free the plunger from the stand-by position.
