| 20120125334 | HUMIDIFICATION SYSTEM - The present invention provides a method and apparatus for reducing condensed humidifying agent in a humidification system by pulsing a delivery of humidifying agent into a respiratory circuit. During a non-pulsed interval, gas flowing through the respiratory circuit will evaporate the condensed humidifying agent present in the respiratory circuit. The present invention also provides a method and apparatus for delivering humidified gas to a patient, wherein the delivery avoids the problems associated with a stationary water humidifier. In the method, the delivery of humidifying agent is precisely controlled to deliver a flow of humidifying agent to a volume of gas. | 05-24-2012 |

| 20100221193 | COLOR CHANGE SURGICAL PREP SOLUTION - This invention discloses a surgical prep solution formulation, either film forming or non-film forming, that changes color upon a change in pH to indicate that the solvent has sufficiently evaporated. The major components of this surgical prep solution include: antimicrobial agents, solvents, pH adjusters, color changing pH indicators, and optionally: film forming polymers, dyes and viscosity regulators. The pH of the solution may rise or fall depending on the pH of the original solution as compared with the normal pH range of the acid mantle of the human skin or the normal pH range of a sterilizing solution. As the pH changes, the pH indicator may cause the surgical prep solution to change color. Concurrently, as the fluids evaporate, the pH indicators interact with atmospheric CO | 09-02-2010 |
| 20100108073 | NASAL INTERFACE PRONG DEVICE - An infant nasal interface prong device for use with an nCPAP system. The device includes first and second nasal prongs and a base. Each prong includes a bellows segment, a tip, and a lumen. The tip extends from the bellows segment to a tip end and is adapted for insertion with an infant's naris. The lumen extends through the tip and the bellows segment. In an undeflected state, a central axis of the lumen along the bellows segment is transversely offset from the lumen axis at the tip end. The base is connected to each of the nasal prongs and is adapted for coupling to a CPAP generator. The bellows segment renders the corresponding prong highly flexible relative to the base. The offset positioning of the tip end promotes desired positioning of the base/CPAP generator, relative to the patient and more closely conforms to the expected nasal anatomy. | 05-06-2010 |
