Abstract: Embodiments described herein relate generally to biosensing garments, and in particular, to systems and methods for monitoring respiration in a biosensing garment, whereby an improved integration of the respiration monitoring circuit into the garment is achieved, resulting in improved signal quality and durability. In some embodiments, an apparatus includes an elongate member having a longitudinal axis and configured to be stretchable along its longitudinal axis. The elongate member includes a plurality of elastic members (e.g., a first elastic member, a second elastic member, and a third elastic member) that extend along the longitudinal axis. A conductive member is coupled to the first, second and third members, and forms a “curved” pattern along the longitudinal axis of the elongate member. The conductive member is configured to change from a first configuration to a second configuration as the elongate member stretches along its longitudinal axis.

Abstract: A ligature-resistant bag hanger for supporting an intravenous (IV) bag prevents formation of ligatures over an IV pole and on the bag support hooks. Internal components of the ligature-resistant IV bag hanger are enclosed in a housing. The internal components of the ligature-resistant bag hanger include one or more bag support hooks that have an extension portion extending from an interior of the housing and that are rotatable around an axle located within the housing. In a reset position, the bag support hook(s) support(s) an intravenous bag in a saddle portion of the hook up to a threshold weight limit. In a triggered position, initiated by a downward force in excess of the threshold weight limit rotating the hook downward, the hook rotates so that an attempted ligature formed above the saddle portion of the hook is released by retraction of the saddle portion of the within the housing.
