Abstract: A drug delivery device is provided, including a housing, a drug storage container, a plunger, a plunger biasing member, a releaser, and a shock absorber. The housing defines a longitudinal axis and has an opening. The drug storage container includes a barrel, a stopper, and a delivery member, where the stopper is movably positioned within the barrel. The delivery member is positioned at a distal end of the barrel and has an insertion end configured to extend at least partially through the opening during a delivery state. The plunger is moveable toward the distal end of the drug storage container to engage the stopper and expel a drug from the drug storage container through the delivery member. The plunger biasing member is coupled with the plunger and configured to urge the plunger toward the distal end of the drug storage container.

Abstract: A modular climbing tree that includes a plurality of poles and connecting components configured for connecting the poles and accessories. At least one connecting component has a first connecting part configured for fastening to a pole or surface and an opposite second connecting part having at least one male coupling element and at least one female coupling element for engaging and locking with mating coupling elements of another connecting component. The male and female coupling elements on opposing connecting components are engaged to interlock. Thereafter the opposite connecting components are rotated about their common axis to further lock together in a detachable manner.
