Abstract: A phototherapy system and device is disclosed, including an array of light sources from at least two distinct spectral light regions. The first spectral light region represents the treatment color, and thus is chosen for its phototherapeutic value. For instance, blue light may be the treatment color for hyperbilirubinemia. The second spectral light region represents the balancing color, and is chosen for its ability to mitigate discomfort that may be caused by viewing the treatment color. When blue is the treatment color, yellow has been found to be an effective balancing color.

Abstract: A method of providing phototherapy to a patient. In some embodiments, the method includes the steps of placing a patient on a rigid support surface of a phototherapy device, the support surface being adapted to support the patient without substantial deformation; transmitting light from a light source through a first portion of the support surface to the patient; and limiting light transmission from the light source through a second portion of the support surface.

Abstract: Highly sensitive devices for detecting nitric oxide and/or other gaseous analytes in gaseous samples are improved by the incorporation of a carbon monoxide scavenger in the interior of the device or in the device packaging. The release of carbon monoxide within the housing of the device by the plastic used in the construction of the housing or by anything within the device that releases carbon monoxide causes a loss in sensitivity due to competition between the carbon monoxide and the nitric oxide for the binding sites on the device sensor. The scavenger corrects this by either catalyzing the oxidation of carbon monoxide to the less competitive carbon dioxide or immobilizing the carbon monoxide by affinity-type or covalent binding. Analogous effects are achieved for analytes other than nitric oxide but that likewise encounter interference from carbon monoxide in binding to sensors.

Abstract: A phototherapy system having a rigid support surface adapted to support a patient without substantial deformation; a light source disposed so as to transmit light through the support surface; and a mask adapted to permit light transmission from the light source through a first portion of the support surface and to limit light transmission from the light source through a second portion of the support surface.

Abstract: A phototherapy system and device is disclosed, including an array of light sources arranged so as to achieve substantially uniform distribution of light on a subject. The light sources can be arranged in a number of configurations, including but not limited to distributions in which the density of lights sources is greater in the periphery than in the center. The present invention also includes a light diffusing panel to increase exposure uniformity, and a targeting mechanism to ensure that the device is properly aligned over the subject.

Abstract: A measurement device for generating an arterial volume-indicative signal includes an exciter and a detector. The exciter is adapted to receive an oscillating signal and generate a pressure wave based at least in part on the oscillating signal on the artery at a measurement site on a patient. The pressure wave includes a frequency. The detector is placed sufficiently near the measurement site to detect a volumetric signal indicative of arterial volume of the patient.

Abstract: The flow rate of a gaseous sample of exhaled breath through an analytical device is controlled by a pump, and in certain embodiments two pumps. Placement of the analyte sensor in a secondary stream branching off of the primary stream through the device offers further control over the manner, duration, and quantity of the breath that is placed in contact with the sensor.

Abstract: A system and method for controlling the flow rate of a gaseous sample in an exhaled breath analysis system is disclosed. Two embodiments are described in this patent: a single pump embodiment and a dual pump embodiment. In each of these embodiments, a pump or pumps are used to control the flow rate of the breath sample as it moves through the analysis system. Also, the system includes means to conduct side stream, stopped flow analysis.
