Abstract: A sensor for detecting concentration of a component in a breath sample including a gas sampling cell having an inlet, an outlet, a light source, a first light detector, a sampling channel configured to receive gas samples from the inlet; the sampling channel defining a light path between said light source and said first light detector; and a volume occupying material located within the sampling channel, the volume occupying material having an absorption coefficient for mid-infra-red light below 0.5 cm?1 at room temperature.

Abstract: A filtering device for use in breath sampling including a filter configured to absorb moisture, a first connector configured to allow connection of a user interface to the filtering device, and a second connector configured for connection to the gas analyzer; wherein the filter is essentially flat, such that when the filtering device is connected to a gas analyzer, the filter is in-line with a panel of the gas analyzer; and wherein a circumference of the first and second connectors are smaller than a circumference of the filter.

Abstract: A tubeless patient interface including a grasping member configured to grasp a patient's nose or tooth; and a miniature CO2 sensor attached to the grasping member and configured to measure the concentration of CO2 from a patient's breath flow.

Abstract: Breath sampling tube having an array of reservoirs, the array of reservoirs including a first reservoir proximate to a device end of the tube and at least one intermediate reservoir; the first reservoir having an inner wall defining a channel, a hydrophobic element and a hydrophilic element; and the at least one intermediate reservoir having an inner wall defining a channel and a hydrophilic element; wherein the array of reservoirs is configured to allow unabsorbed water vapor to proceed through the at least one intermediate reservoir while essentially blocking unabsorbed water vapor from passing through the first reservoir.

Abstract: Provided is a foldable curtain rod configured for mounting thereon a curtain. The rod includes at least two elongated rod segments consecutively articulated to one another via a coupling arrangement allowing pivotal displacement of one rod segment with respect to the other. Each of the rod segments is configured for supporting a respective portion of the curtain, extending along a hanging line. The curtain rod is configured for assuming at least a first, deployed position in which the rod segments are essentially axially aligned to provide the curtain rod with a maximal span thereof and a second, folded position in which the rod segments are substantially parallel to one another to provide the curtain rod with a minimal span thereof. In the second, folded position, the hanging lines of the respective rod segments are spaced from one another.

Abstract: A device adapted to be inserted into a lumen, the device having a longitudinal axis and comprising: a) a support element extending along the longitudinal axis; b) a tool mechanically mounted on the support element and being adapted to be used near a wall of the lumen on at least a first side of the longitudinal axis; and c) element, the balloon having at least one portion that is less radially expandable than at least one other portion of the balloon, at a same axial position along said support element.
