20110120457 | ADAPTER FOR USE IN AN AEROSOL DELIVERY SYSTEM - According to one aspect of the present invention, an aerosol inhalation system includes a first conduit member for delivering medication in the form of aerosol particles to a patient. The system includes a first holding chamber for holding the aerosol particles prior to deliver to the first conduit member and a valve mechanism associated with the first conduit member. The system also includes a first device in fluid communication with the first holding chamber for producing the aerosol particles and being sealingly yet releasably received within an adapter that forms an entrance into the first holding chamber. The adapter has a compressible material disposed thereon which is at least partially compressed by insertion of the first device to form the seal between the first device and the adapter. The aerosol inhalation apparatus is a closed system and is therefore capable of delivering a fixed concentration of the medication to the patient due to a valve of the valve mechanism being closed when the patient inhales and the medication is delivered to the patient. | 05-26-2011 |
