Abstract: A float retention arrangement and related methods for a humidification chamber that includes at least one float that operates an inlet valve that controls a flow of water through a water inlet opening of the humidification chamber. A cover of the humidification chamber defines an interior space, at least one gas port and a float retention opening. A component forms at least a portion of a water supply conduit for supplying water from a water source to the water inlet opening. The component is insertable into the float retention opening and is positionable to contact and retain the at least one float in a non-use position. In some configurations, the component can be a water spike.

Abstract: The present invention relates to an absorbent structure, preferably for use in absorbent products, such as used in the food, consumer, household, building and construction, beauty and medical industry, and as used in the personal hygiene industry. The substantially cellulose free absorbent structures continuously immobilise absorbent polymer material via initial smaller pockets and subsequently larger compartments allowing excellent fluid management of the absorbent polymer material in dry, partially and fully liquid loaded state. Preferably such absorbent structure volume increases are result of temporary secondary attachment patterns made in combination with substantially permanent primary attachment grids allowing the release of bigger volumes from the initial smaller volumes by detachment of the secondary attachments.

Abstract: A nasal drug delivery device for delivering a plume derived from a propellant and a drug compound. The drug compound is in an intranasal dosage form in the form of powder, suspension, dispersion, or liquid. The propelled intranasal dosage form is deposited within the upper nasal cavity such as the olfactory region. The drug deposited within the olfactory region is delivered to the brain avoiding the blood-brain-barrier. Hydrofluoroalkane propellant from a pressurized canister is channeled to a diffuser and drug-containing channel where the intranasal dosage form is aerosolized. The aerosolized intranasal dosage form passes through a nozzle thus delivering a plume to the user's upper nasal cavity.

Abstract: A preflushing unit (10) preflushes a breathing gas circuit (210) of a closed-circuit respirator (200). A basic body (20) has an inlet port (22), feeding breathing gas from a breathing gas supply (220), an outlet port (24) discharging breathing gas into the breathing circuit, and a flow section (32) fluid connecting a valve chamber (30). A valve body (40) with a sealing surface (42) is arranged in the valve chamber (30). An elastomer body (50) with a counter-sealing surface (52) in the valve chamber, fluid tight separates the flow section from a control section (34). The counter-sealing surface acts with a sealing force against the valve body for sealing the flow section. A control port (26) of the basic body provides a controlled feed of breathing gas from the breathing gas supply into the control section for pressure equalization between the flow section and the control section.

Abstract: A pulse modulated oxygen dispensing and pressurization system provides a variable range of controlled oxygen bolus to an enclosed breathing environment supporting and maintaining required pressure conditions in accordance with desired flow demand. As oxygen is consumed by the user from within the enclosed breathing environment, the exhaled gases and moisture are conditioned or vented to acceptable levels by additional systems associated with the environment. These additional systems cause an ongoing need to replenish the oxygen within the environment and maintain the required partial pressure of oxygen. Specific to one of a plurality of modes of operation, the system responds to changes in regulated output pressure by delivering a precisely metered periodic bolus volume of oxygen to support a requirement of the environment volume. The bolus is variable based on a plurality of factors to increase and decrease changes in rates of flow required to maintain regulated pressure.

Abstract: This invention relates to a compliance monitor for monitoring patient usage of a medicament delivery device, where the medicament delivery device includes a store of medicament and a medicament dispensing means. The compliance monitor includes a housing adapted to enclose the medicament delivery device, and a dose counter, associated with the housing, for recording the delivery of a dose of medicament to the patient from the medicament delivery device.
