Abstract: A breathing motion simulator for simulating an expanding and retracting movement of live breathing, includes a pump and an inflatable bladder for generating a repetitive motion resembling a breathing motion. The simulator includes a cover plate positioned across the bladder and a cover guidance for linearly guiding the cover plate with respect to a base body. The cover guidance includes at least a first living hinge unit and a second living hinge unit oriented in a non-parallel direction with respect to each other for constraining a rotational movement of the cover plate, where each living hinge unit includes at least three stacked living hinges defining a set of three pivot axes in parallel for allowing a translational movement of the cover plate, such that the cover guidance enables a linear movement of the cover plate.

Abstract: A haptic respiration simulator includes: a pump unit; an accumulator for reducing noise originating from a pumping action of the pump, the accumulator being in fluid communication with an outlet of the pump; and a pump suspension system for reducing noise originating from operation of the pump, including: a tubular casing for receiving the pump unit at an inside thereof, the tubular casing having a substantially closed circumferential wall that prevents at least a part of the sound waves resulting from operation of the pump to transfer outside the tubular casing; an inner suspension for suspending the pump with respect to the tubular casing, the inner suspension being positioned between the pump and the tubular casing; a pair of end caps for sealing the tubular casing, and an outer suspension for suspending the tubular casing with respect to a housing.
