Abstract
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.
Claims15
A pressurized metered dose inhaler receptacle comprising:
- a socket component defining a recess shaped to receive a portion of a medicament container, wherein the socket component is coupled to a holding chamber having an interior space;
- and
- a discharge nozzle comprising a well shaped to receive a valve stem of the medicament container and a nozzle portion comprising an orifice in fluid communication with the well, wherein the discharge nozzle is removably secured in the recess of the socket component in an operative position such that the nozzle portion is disposed in the interior space of the holding chamber and the orifice is in fluid communication with the interior space of the holding chamber, and wherein the discharge nozzle is non-moveable relative to the socket when the discharge nozzle is in the operative position.
A pressurized metered dose inhaler receptacle comprising:
- a holding chamber having an interior space, wherein the interior space of the holding chamber has an output opening, and wherein the holding chamber has an input opening spaced apart from the output opening;
- a one-way valve disposed adjacent the input opening and coupled to the holding chamber to permit one-way flow through the input opening into the interior space of the holding chamber;
- a socket component defining a recess shaped to receive a portion of a medicament container, wherein the socket component is spaced apart from the output opening;
- and
- a discharge nozzle comprising a well shaped to receive a valve stem of the medicament container and an orifice in fluid communication with the well, wherein the discharge nozzle is removably secured in the recess of the socket component, wherein the orifice is in fluid communication with the interior space of the holding chamber, wherein the discharge nozzle comprises a flange portion disposed in the socket component and a nozzle portion extending from the flange portion, wherein the orifice is positioned on the nozzle portion, and wherein the discharge nozzle comprises an arm extending into the interior space of the holding chamber, the arm located to prevent the dislodgement of the one-way valve from the holding chamber.

A pressurized metered dose inhaler receptacle comprising:
- a socket component defining a recess shaped to receive a portion of a medicament container, wherein the socket component is coupled to a holding chamber having an interior space;
- and
- a discharge nozzle comprising a first well shaped to receive a valve stem of the medicament container and a nozzle portion comprising a first orifice in fluid communication with the first well, wherein the discharge nozzle is removably secured in the recess of the socket component such that the nozzle portion is disposed in the interior space of the holding chamber and the first orifice is in fluid communication with the interior space of the holding chamber, and wherein the discharge nozzle further comprises a second orifice and a second well communicating respectively with the second orifice.
A method of reconfiguring a medication delivery apparatus comprising:
- inserting a first discharge nozzle comprising a first nozzle portion having a first orifice into a receptacle such that the first discharge nozzle is in a first operative position, wherein the first nozzle portion is disposed in an interior space of a holding chamber, the first orifice is in fluid communication with the interior space of the holding chamber and the first discharge nozzle is non-moveable relative to the receptacle when the first discharge nozzle is in the first operative position;
- coupling a first medication container to the first discharge nozzle;
- removing the first discharge nozzle from the receptacle;
- inserting a second discharge nozzle comprising a second nozzle portion having a second orifice into the receptacle such that the second discharge nozzle is in a second operative position, wherein the second nozzle portion is disposed in the interior space of the holding chamber, the second orifice is in fluid communication with the interior space of the holding chamber, and the second discharge nozzle is non-moveable relative to the receptacle when the second discharge nozzle is in the second operative position, and wherein the first and second discharge orifices are different sizes;
- and
- coupling a second medication container to the second discharge nozzle.
