Abstract
A variable volume medicament valve, inhaler; and method of treatment including a housing, and a plug insertable into the housing wherein a volume of medicament to be released by the valve is defined by a distance between a lower surface of the plug and a top surface of the housing and wherein the volume is variable.
Claims39
A variable volume medicament valve comprising:
- a. a housing;
- and
- b. a plug insertable into said housing wherein a volume of medicament to be released by said valve is defined by a distance between a lower surface of the plug and a top surface of the housing and wherein said volume is variable.
A variable dose metered inhaler comprising:
- a. an inhaler body;
- b. a canister for storage of one or more pressurized doses of a medicament which is placed in the inhaler body;
- and
- c. a dose variable valve, said dose variable valve including a valve housing and a valve plug, wherein a volume of drug to be administered can be varied by movement of the valve plug in relation to the valve housing.
A breath actuated variable dose metered inhaler comprising:
- a. an inhaler body having a mouth piece;
- b. a canister for storage of one or more pressurized doses of a medicament which is placed in the inhaler body;
- c. a dose variable valve, said dose variable valve including a valve housing and a valve plug, wherein a volume of drug to be administered can be varied by movement of the valve plug in relation to the valve housing;
- and
- d. a breath actuated trigger which releases the volume of drug to be administered to the mouthpiece upon inhalation by a user.
A variable dose metered nasal drug delivery device comprising:
- a. a nasal drug delivery device body having a mouthpiece and a nose piece;
- b. a canister for storage of one or more pressurized doses of a medicament;
- c. a dose variable valve, said dose variable valve including a valve housing and a valve plug, wherein a volume of drug to be administered can be varied by movement of the valve plug ill relation to the valve housing;
- and
- d. a breath actuated trigger which releases the volume of drug to be administered to the nosepiece upon the exhalation of a user into the mouthpiece.
A method of treatment of a condition in need thereof by application of a drug effective for the treatment thereof comprising steps of:
- a. providing an inhaler;
- b. providing a pressurized container having a medication;
- c. setting a dose based upon the need of the patient;
- d. inhaling on a mouthpiece of the inhaler;
- and
- e. delivering the set dose to the patient.
A method of varying the volume of a valve for release of a pressurized material comprising:
- providing a variable volume medicament valve having a housing, and a plug insertable into the housing wherein a volume of medicament to be released by said valve is defined by a distance between a lower surface of the plug and a top surface of the housing;
- and rotating the housing relative to the plug to change the distance.
