Inhalation device for producing a drug aerosol

A device for delivering a drug by inhalation is disclosed. The device includes a body defining an interior flow-through chamber having upstream and downstream chamber openings, and a drug supply unit contained within the chamber for producing, upon actuation, a heated drug vapor in a condensation region of the chamber. Gas drawn through the chamber region at a selected gas-flow rate is effective to form drug condensation particles from the drug vapor having a selected MMAD between 0.02 and 0.1 MMAD or between 1 and 3.5 μm. A gas-flow control valve disposed upstream of the unit functions to limit gas-flow rate through the condensation region to the selected gas-flow rate. An actuation switch in the device activates the drug-supply unit, such that the drug-supply unit can be controlled to produce vapor when the gas-flow rate through the chamber is at the selected flow rate.

Non-invasive intraoral electrical stimulator system and method for treatment of obstructive sleep apnea (OSA)

InactiveUS20140135868A1Easy to installEasily removable retainerHead electrodesSnoring preventionDilatorClosed loop
A non-invasive, removable intraoral electrical Stimulator or Pacemaker system and method is described, for electrically-stimulating and re-establishing the tone in the upper pharyngeal dilator muscle, the genioglossus and base-of-tongue muscles, for the treatment of Obstructive Sleep Apnea (OSA) in human adults and young adults. The Stimulator system consists of an intraoral Stimulator device assembly with a rechargeable battery, an external (inductive) Recharger appliance and an external hand-held (inductive) Programmer appliance. The Stimulator device assembly is inserted into the mouth by the OSA patient before sleep time and is removed when awake or during normal activity and placed in the charging cradle of the Recharger appliance for recharging the device battery. The physician uses the hand-held Programmer appliance to determine and set the patient-specific stimulation therapy parameters in the device, at the patient's initial evaluation. The stimulation therapy is delivered either in an open loop configuration without regard to patient's respiration activity, or in a closed loop configuration synchronized to the patient's respiration detected by one or more sensors in the system.

7FAstage 1 abradable coatings and method for making same

A method of applying a profiled abradable coating onto a substrate in which an abradable ceramic coating composition is applied to a metal substrate using one or more coating application techniques to produce a defined ceramic pattern without requiring a separate web or grid to be brazed onto the substrate. The invention is particularly designed to withstand the higher operating temperatures encountered with the stage 1 section of 7FA+e gas turbines to allow for increased coating life without significant deterioration in structural or functional integrity. Typically, the grid pattern coating begins approximately 0.431″ after the leading edge of the shroud, and ends approximately 1.60″ before the trailing edge of the shroud. In the case of diamond-shaped patterns, the grid pattern will be about 0.28″ long and 0.28″ wide, with an overall thickness of about 0.46.″ The coatings thus provide the required levels of abradability and leakage performance and may be applied as a chevron or diamond pattern with the shape oriented such that the diagonals run perpendicular and parallel to the sides of the shroud.

Dual evaporator for indoor units and method therefor

A dual (or multi) sectional evaporator system comprising first and second (or more) evaporator sections capable of cooling the air supply through the evaporator. The first evaporator section is positioned upstream of the second evaporator section (second upstream of the third and so on). However, the warmest refrigerant passes through the first evaporator section and the coldest refrigerant passes through the second evaporator section (or last evaporator section if more than two sections), such that the air supply is precooled prior to reaching the second (or last) evaporator. Providing a two (or more) passes of refrigerant through the dual (or multi) sectional evaporator system increases the superheat temperature out of the first evaporator up to about 25 degrees Fahrenheit, and / or increases the mass flow of refrigerant because of the increased heat exchange efficiency provided by counterflow heat exchange. Moreover, in the preferred embodiment for an A-coil or slant coil, the second evaporator section is positioned over the top of the first evaporator section such that the second evaporator overlays the first evaporator section in order to maximize the use of available space. Also, A-coil or slant coil forms of the present invention are configured such that they include contoured cut-out shaped corner portions wherein the squared corners of the evaporators are substantially eliminated thereby eliminating the dead air flow spaces typically associated with other known evaporators. The elimination of the dead air space allows the system to operate at a lower fan speed as well as allows the system to be constructed and operate within smaller confines.

A patient transfer device includes a mat, with an upper side and a gas permeable lower side. The mat includes a chamber between its upper and lower sides, which is operable to be in fluid communication with an air source such that when air flows into the mat, the air will flow into the chamber and through the gas permeable lower side to form an air film between the mat and a surface on which the mat is supported at its lower side. In addition, the lower side of the mat is substantially planar when the mat is inflated. A system for controlling the inflation of the mat may be used that automatically adjusts for the inflation of the mat during patient transfer.

Methods and devices to induce controlled atelectasis and hypoxic pulmonary vasoconstriction

Lung conditions are treated by implanting a flow restrictor in a passageway upstream from a diseased lung segment. The restrictor will create an orifice at the implantation site which inhibits air exchange with the segment to induce controlled atelectasis and / or hypoxia. Controlled atelectasis can induce collapse of the diseased segment with a reduced risk of pneumothorax. Hypoxia can promote gas exchange with non-isolated, healthy regions of the lung even in the absence of lung collapse.

Airflow assisted ramp loading and unloading of sliders in hard disk drives

Windage proximate to a spinning disk within a disk drive is directed through a plurality of apertures in a ramp situated near the outside diameter of the disk. A tab extending from a load beam that supports a slider rests on the ramp when the drive is not in use. When the drive is started the disk begins to spin and an actuator moves the load beam to bring the slider over the surface of the disk. As the load beam moves, the tab is guided along the ramp and cushioned by the air flow emerging from apertures in the ramp beneath it. When the drive is stopped the actuator brings the load beam back so that the tab engages the ramp. A cushion of air is again provided as the tab is moved along the ramp as the tab is returned to a parked position.
