Abstract: An embodiment provides a non-invasive ventilation patient interface. In one example, the patient interface includes a conduit having an entrainment opening and a nasal opening. The patient interface includes an orifice proximate to the entrainment opening and configured to expel a jet of gas and a surface having a first end and a second end, the first end being proximate to the orifice and extending substantially parallel to a flow direction of the jet of gas expelled from the orifice, the second end being closer to the nasal opening than the first end. In an operational state, the jet of gas adheres to the surface via Coanda effect, thereby entraining ambient air into the entrainment opening to deliver the jet of gas and the ambient air through the nasal opening of the conduit.

Abstract: Provided is a system (300) for determining a sweat rate per gland and measuring biomarker concentration. The system comprises an apparatus and a sensor (166). The apparatus receives sweat from the skin and transports the sweat as discrete sweat droplets to the sensor. The sensor senses each of the counted sweat droplets. The system further comprises a processor which counts the number of sensed sweat droplets during a time period. The processor also determines time intervals between consecutive sensed sweat droplets, and receives a measure of the volume of each of the counted sweat droplets. The time intervals and the measure of the volume are then used by the processor to identify sweat burst and rest periods of the sweat gland or glands producing the sweat. This identification process necessarily involves assigning the sweat burst and rest periods to the sweat gland or glands, such that the processor is permitted to determine the number of sweat glands involved in producing the sweat.

Abstract: Provided is an apparatus (100) for transporting sweat droplets (112) to a sensor. The apparatus comprises a chamber (102) for filling with sweat. The chamber has an inlet (104) lying adjacent the surface of the skin (106), which inlet permits sweat to enter and fill the chamber. The chamber has an outlet (114) from which a sweat droplet protrudes once the chamber has been filled. The apparatus further comprises a fluid transport assembly which is designed to enable the sweat droplet protruding from the outlet to become detached from the outlet of the chamber. The sweat droplet is subsequently transported by the fluid transport assembly to the sensor. Once the protruding droplet has been released from the outlet, the outlet is made available for a subsequent sweat droplet to protrude therefrom upon further filling of the chamber.

Abstract: An implantable blood flow control system has an open passageway defined inside a radially inner wall, behind which is a closed passageway. The radially inner wall includes electroactive polymer actuator members for providing a variable flow restriction. The flow restriction has an undulating shape so that the volume of the closed passageway may remain constant during actuation of the electroactive polymer actuator members. In this way, the chamber behind the actuator members does not impede free movement of the actuator members. The undulating pattern presents no sharp edges, where blood coagulation could otherwise occur.
