Abstract: Devices and methods are described herein for directly and accurately measuring sweat flow rates using miniaturized thermal flow rate sensors. The devices (100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500) include the flow rate sensors (220, 320, 420, 520, 620, 720, 820, 920, 1020, 1120, 1220, 1320, 1420) in or adjacent to a microfluidic component (230, 330, 430, 530, 630, 730, 830, 930, 1030, 1130, 1230, 1330, 1430, 1530) of a wearable sweat sensing device. The devices and methods optimize the sensitivity of the flow rate sensors, while minimizing the presence of noise, in order to accurately and directly measure sweat flow rates.

Abstract: A scented mask is disclosed that includes: a filter region with one or more pleats that include a mask material and a pleat fold; and one or more scented patches. Each scented patch includes a patch lid attached to the mask material before the pleat fold; a patch-impermeable layer attached to the mask material after the pleat fold; and a layer impregnated with a scent agent attached to the patch-impermeable layer. The mask is constructed to transition from a sealed configuration to an unsealed configuration when a user places the mask over her nose and mouth: the sealed configuration where the mask material before and after the pleat fold are folded on each other and the patch lid covers and seals the impregnated layer, inhibiting the vaporization of the scent agent; and the unsealed configuration where the pleat fold is opened and the patch lid is separated from the impregnated layer, allowing for the vaporization of the scent agent.

Abstract: A stabilization and support for a catheter provides stress distribution for the loads otherwise imposed by the catheter interface hardware such as the base and hub components that may otherwise cause stresses in the skin and associated damage and sores. A mount is sized to support a catheter installation extending substantially tangentially to the surface of the skin of a subject, thus permitting stabilization of the catheter without exposing the skin to the sharp, highly stressful edges of catheter equipment. A transparent securement renders the catheter available for visual inspection of the condition of the catheter and the surrounding skin.

Abstract: An improved dress shield comprising a laminar structure in a simple elliptical shape, having a centrally located transverse elliptical central panel in the facing layer, said panel comprising an ultra limp, drapable fabric which gives unrestricted movement and good fit along the underarm seam of a garment, and increases the range of movement of the shield.
