Embodiment Construction

[0032] figure 1 A variable dose valve 10 according to the first aspect of the invention is shown. shown in exploded form figure 1 The variable dose valve 10 is shown in detail to show its components. The variable dose valve 10 includes a ferrule 12 which enables the valve 10 to be connected to a tank containing a medicament and a propellant (in figure 1 not shown in ). The lower stem seal 14 rests on the inner surface 16 of the ferrule 12 . The diameter of the inner surface 16 substantially matches the diameter of the lower stem seal 14 . The lower stem seal 14 prevents medicament leaks from escaping along the shaft exterior of the lower stem 32 when the valve 10 is actuated. The lower stem seal 14 also prevents debris and dirt from entering the valve 10 . The metering chamber housing 18 rests on top of the lower stem seal 14 . The metering chamber housing includes a lower flange 20 which substantially conforms to the surface 22 when the lower flange 20 is inserted into...

Abstract

A variable volume medicament valve (10), inhaler, and method of treatment including a housing, and a plug (44) 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.

Description

technical field [0001] The present invention relates to metered dose aerosol cans, and more particularly to a metered dose aerosol can providing a variable valve for administering a desired amount of medicine on demand. Background technique [0002] Diabetes is a disease that affects millions of people in the United States and millions of people around the world. For diagnosed diabetes, the usual treatment is insulin therapy. Generally, diabetics self-administer insulin by injection. Diabetes is one of the few diseases for which doctors routinely allow patients to self titrate, ie to determine the exact amount of dosage delivered to the patient himself at any given time. This dose variability creates problems when attempting to deliver doses through devices other than traditional injections. [0003] In order to provide a non-invasive means of administering insulin and other systemic drugs and thereby obviate the need for syringes, aerosolized formulations have been theor...
