摘要:
Disclosed herein is a pharmacophore model for inhibiting Botulinum neurotoxin A metalloprotease activity which comprises a first plane A, a second plane B, a first hydrophobic moiety C, a second hydrophobic moiety D and a positive ionizable substituent E. The pharmacophore model may further comprise a heteroatom in the first plane A. In some embodiments, the distance between the center of the first plane A and the center of the second plane B is about 6.5 to about 9.5 Å. In some embodiments, the distance between the center of the first hydrophobic moiety C and the center of the second hydrophobic moiety D is about 8.0 to about 16.0 Å. In some embodiments, the distance between the center of the first plane to the center of the first hydrophobic moiety C is about 3.0 to about 5.0 Å. In some embodiments, the distance between the center of the second plane to the center of the second hydrophobic moiety C is about 3.0 to about 5.0 Å. In some embodiments, the distance between the center of the first plane to the center of the positive ionizable substituent is about 6.5 to about 9.5 Å.
摘要:
An oscillating positive expiratory pressure device comprising a housing enclosing at least one chamber, a chamber inlet configured to receive exhaled air into the at least one chamber, and a chamber outlet configured to permit exhaled air to exit the at least one chamber. A channel is positioned in an exhalation flow path between the chamber inlet and the chamber outlet, with the channel being moveably connected to a chamber of the at least one chamber. An air flow regulator is moveable with respect to the channel between a first position, where the flow of air through the channel is restricted and a second position, where the flow of air through the channel is less restricted, the air flow regulator being configured to repeatedly move between the first position and the second position in response to a flow of exhaled air.

A ventilator assembly includes a housing defining an inhalation interior space and an exhalation interior space separate from the inhalation interior space. A ventilator port is positioned at a first location of the housing and defines a first passageway in communication with the inhalation interior space and the exhalation interior space. A patient port is positioned at a second location of the housing and defines a second passageway in communication with the inhalation interior space and the exhalation interior space. A one-way inhalation valve permits one-way flow from the ventilator port to the patient port through the inhalation interior space and a one-way exhalation valve permits one-way flow from the patient port to the ventilator port through the exhalation interior space. A receptacle is in communication with the inhalation interior space and is operative to receive a container comprising an aerosolized medication.
摘要:
An adapter for use in a breathing circuit including a housing with a conduit having a ventilator port adapted to be coupled to a breathing circuit and a patient port adapted to communicate with a patient interface. A medicament container receptacle communicates with the conduit between the ventilator port and the patient port. The receptacle includes a support block having a well shaped to receive a valve stem extending from a container of medicament and an actuator finger extending upwardly in the receptacle adjacent the support block. The actuator finger is adapted to actuate a dose counter coupled to the container.
摘要:
A flow indicating system that includes a conduit that contains a substance, wherein the conduit defines a path along which the substance primarily flows and a viewing port attached to the conduit and the viewing port prevents substantially non-ambient atmosphere gases and substances from escaping therefrom and allows visualization of an internal space defined by the viewing port. A flow indicator that is positioned within the conduit so as to be viewed via the viewing port and is positioned so as to not to substantially interfere with a flow of the substance along the path.
摘要:
An indicating device suitable for indicating the number of dosages of a substance that have been dispensed from or remain in a container. The indicating device includes an indicator member having an outwardly facing first surface with indicia visible to a user and an opposite inwardly facing surface having a plurality of teeth. The first surface further includes a groove. A cover is disposed over at least a portion of the first surface of the indicator member such that only a portion of the indicia are visible at any one time. The cover includes an inwardly extending projection disposed in the groove. The indicator member is rotatable relative to the cover with the projection being moveable in the groove as the indicator member is rotated relative to the cover. In another aspect, a rotatable member is rotatable relative to an outer cover. An intermediate member is moveable relative to the outer cover and the rotatable member so as to obscure at least a portion of the surface of the rotatable member that would be otherwise visible through the viewing window. At least one of the surfaces of the rotatable member and intermediate member have dosage indicia.
摘要:
A breathing assistance apparatus includes an inner volumetric member pressurizable from a first pressure to a second pressure and an outer volumetric member surrounding at least a portion of the inner expandable volumetric member. The inner volumetric member pressurizes the outer volumetric member as the inner volumetric member is pressurized from the first pressure to the second pressure. In another embodiment, a breathing assistance apparatus includes exhalation and inhalation chambers with respective biasing members providing for the exhalation chamber to apply a pressure to the inhalation chamber and thereby provide assisted inhalation. Methods for assisting breathing are also provided.
