ABSTRACT:
According to one aspect of the present invention, an aerosol inhalation system including an accessory is defined by a first conduit member for delivering medication in the form of aerosol particles to a patient, as well as a first holding chamber for holding the aerosol particles prior to deliver to the first conduit member. The accessory includes a valve mechanism associated with the first conduit member and including a first valve assembly and a second valve assembly. The aerosol inhalation system includes at least one device in fluid communication with the first holding chamber for producing the aerosol particles. For example, the device can be either an MDI, a nebulizer or both devices can be used simultaneously. According to one exemplary embodiment of the present invention, the aerosol inhalation system is a closed system and is therefore capable of delivering a fixed concentration of the medication to the patient, thereby overcoming the above deficiencies that are associated with the prior art devices.
