摘要： A medical valve has an interior flow path having a volume that is substantially the same when in either the closed mode (when the valve is closed) or the open mode (when the valve is open). To those ends, the medical valve has a housing forming an interior, and a valve mechanism (within the interior) having a substantially rigid translating member with a bore. The interior of the housing has a flow path that includes at least a portion of the bore of the translating member. As noted above, the open mode volume is substantially equal to the closed mode volume.

摘要： A medical valve includes a housing having an interior forming an inlet and an outlet. A longitudinally movable member is secured within the interior of the housing. External to the movable member and within the interior is a fluid path. Movement of the movable member controls fluid flow between the inlet and the outlet via the fluid path. The outlet produces no greater than a negligible drawback or positive push during withdrawal of a nozzle.

摘要： A gland member within a medical valve is configured to have a substantially consistent or enlarging internal volume as the valve transitions from a closed mode to an open mode. To that end, the valve has a housing forming an interior containing a flow path, and a stationary post member within the interior. The post member has a lumen that is a part of the flow path. The lumen has an opening to the interior of the housing. The valve further includes a gland member circumscribing the post member to produce a variable volume region formed at least in part between the gland member itself and the post member. In addition, the variable volume region is a part of the flow path, while the gland member occludes the post lumen opening when in the closed mode. The variable volume region has an open volume (i.e., when the valve is in the open mode) that is no less than its closed volume (i.e., when the valve is in the closed mode).

摘要： A dry powder inhaler has a dispersion chamber containing beads. A dose of dry powder is released into the chamber, or into an inlet tangentially joining into the chamber. As the patient inhales on a nosepiece or mouthpiece, air moves circularly through the dispersion chamber to drive the beads. The beads roll, bounce, and collide repeatedly with the drug particles on the chamber surfaces or on the beads. The smaller active drug particles are separated from larger carrier particles and from each other, and a powder aerosol is created and inhaled by the patient. The beads are preferably lightweight, so that they can be rapidly accelerated and moved, even with nominal inspiration. The flow resistance of the inhaler is also reduced via the beads, allowing greater airflow and powder dispersion, without any increased effort by the patient.
