Benefits of technology

"The present invention provides a mouthpiece with a valve for controlling the delivery of aerosolized medicament to a subject. The mouthpiece has an anti-electrostatic interior to reduce the amount of medicament adhering to the walls of the holding chamber and thereby increase the delivery efficiency of the system. The holding chamber is also provided with a receptacle member adapted to accept a source of aerosol medicament, which may aid in the efficient delivery of medicament to the subject. The technical effects of this invention include improved delivery efficiency and ease of use for patients and healthcare professionals."

Problems solved by technology

The housing has a one-piece valve system that permits passage of medicament aerosol to the subject during inhalation, but does not permit the passage of the subject's breath in the upstream direction during exhalation, with the exhaled breath being expelled through an opening in the sidewall of the housing.

BACKGROUND

[0001] The present invention is directed to apparatus for delivering aerosol medicament to a subject in need of the medicament. Delivery systems start with an aerosol-generating device. One common example of such devices is a pressurized metered dose inhaler (MDI). MDIs use pressurized gases to disperse medicament as tiny particles or droplets for delivery to the subject. By depressing the MDI, a known quantity of gas, and thereby of medicament, is ejected from the MDI. MDIs have been used with various types of diverse apparatus, in attempts to improve the delivery of this known quantity of medicament to the subject. Some problems associated with the delivery of medicament in an aerosol form include, but are not limited to, wastage of medicament in the delivery apparatus, delivery at too high speeds so that medicament sticks to the back of the subject's throat or is inhaled into the subject's sinuses rather than being received into the lungs, ejection of medicament out of ...
