摘要:
A medicament delivery device is provided having an oral tubular section for placement in the mouth of a user and a nasal tubular section for placement in the naris of a user. A medicament located in a corrugated, or flexible, section joining the oral tubular section and the nasal tubular section is dispersed into the nasal cavity of the user by blowing into the oral tubular section. A pinch valve or a one way valve is used to prevent the user from accidentally inhaling the medicament. The medicament delivery device may also be used as a pulmonary delivery device into the mouth of a user.
摘要:
Devices and methods are described for preparing, managing, and/or administering metered doses of substances for vaporized administration. In some embodiments, dose cartridges comprising at least one botanical substance include a heating element integrated into the cartridge in close contact with the botanical substance. In some embodiments, cartridge-mounted doses are stored in a magazine, optionally in carousel form, before use. Transport of a cartridge from a magazine to an electrically operated vaporizing chamber which activates the heating element is provided by a mechanical pickup means.

摘要:
A metered dose inhaler (MDI) spacer has a body that defines a dose receiving chamber. A proximal end portion coupled between the body and a mouth port through which a metered dose may be inhaled by a user of the MDI spacer. A distal end portion is coupled with the body. A combined one-way and flow rate control valve coupled with the distal end portion is configured for permitting external airflow into and prohibiting internal airflow out of the dose receiving chamber. A collar coupled with the distal end portion is configured for receiving an actuator shaft of a metered dose inhaler and for forming a seal about an aerosol nozzle of the metered dose inhaler such that a metered dose of medication is admissible into the dose receiving chamber via the collar while airflow into and out of the dose receiving chamber via the collar is prohibited.
摘要:
A ventilator circuit for use in administering medication to a patient includes a housing, a one-way inhalation valve and a one-way exhalation valve. A metered does inhaler receptacle is in fluid flow communication with an interior space of the housing holding chamber. An exhaust conduit communicates between input and output passageways disposed on opposite sides of the interior space.
摘要:
An inhaler for the propellant-free nebulization of a medicament preparation produces a low speed aerosol. The inhaler is combined with an add-on device for intermediate storage of the aerosol produced. The inhaler has a tensioning device for the one-handed tensioning of a drive spring and release thereof. The inhaler is provided with a dispensing device for large animals.
摘要:
A dry powder aerosolizing inhaler which inhales the air current to make the drug powder aerosolize in the inhaler, comprising a main body (11) and a sucker connector (12) connecting the main body. A funnel-type charged hole (1) is mounted in the main body (11), the funnel-type charged hole (1) communicates with the tube of vortex cavity, and the tube of vortex cavity communicates with the sucker (9) of the sucker connector (12).
摘要:
The invention relates to an aerosol therapy device comprising: a housing; an aerosol generator, which is arranged in the housing; an air inlet (52), which is formed in the housing upstream of the aerosol generator (30); and an air outlet (51), which is formed in the housing downstream of the aerosol generator (30) to administer the aerosol produced, wherein an air flow from the air inlet (52) to the air outlet (51) can be generated by a negative pressure at the air outlet (51), wherein said air flow flows around the aerosol generator (30), characterized in that a truncated-cone-shaped flow channel (41), the central axis (44) of which extends in a curved manner, is arranged between the aerosol generator and the air outlet (51).
