摘要:
An improved aerosol medication delivery apparatus and system. The aerosol medication delivery apparatus includes a canister-holding portion and a chamber housing. The canister-holding portion has a receptacle for receipt of a pMDI canister containing a medication and a propellant to provide the aerosol medication delivery system. The canister-holding portion has a discharge orifice communicating with the receptacle to direct an aerosol into an interior of the chamber housing at an input end thereof. The chamber housing also has an output end from which medication can be withdrawn by inhalation by a patient. According to one aspect, the aerosol delivery system includes a containment baffle located at the output end of the chamber housing to partially block the output. According to another aspect, the canister-holding portion and the chamber housing are coupled together by a mechanism that provides for the canister-holding portion to be retracted into the chamber housing for storage. The coupling mechanism also allows the canister-holding portion to be extracted from its storage position in the chamber housing and pivoted into position for use when dispensing medication. In another aspect, an aerosol medication apparatus includes a chamber housing with an input end to receive the discharge of a medication from a pMDI canister and an output end including a containment baffle that partially blocks the output end. The pMDI canister may be received in an elastomeric backpiece that is adapted to accommodate various sizes of actuator boot mouthpieces.

Systems and methods for evaluating medication delivery from valved holding chambers (VHCs) with a facemask using a model face of a child or a model face of an infant are disclosed. Generally, the model face includes a base, an elastomer cast, an air pocket, and a mouth opening. The elastomer cast is positioned on at least a portion of a top of the base. The elastomer simulates soft tissues in a face and defines at least a nose, a chin, and a mouth sized to simulate a nose, a chin, and a mouth of a child. The air pocket is positioned between the base and the elastomer case below at least the nose, the chin, and the mouth of the elastomer cast. The mouth opening defines a passageway through the base, the air pocket, and the mouth of the elastomer cast.

摘要:
An aerosol delivery system is disclosed that is a single-use (disposable) continuous nebulizer system designed for use with mechanically ventilated patients to aerosolize medications for inhalation with a general purpose nebulizer, or for connection with devices usable in endoscopic procedures. The system separates the liquid reservoir from the nebulization process taking place either at the adapter hub, where it fits into an endotracheal tube (ETT), or a gas humidifier, where the aerosol may treat a gas used in an endoscopic procedure, with a multi-lumen tube configured to nebulize liquid and air at its distal end. The refillable liquid reservoir is mounted away from the immediate treatment zone, avoiding orientation issues associated with other types of nebulizers having a self-contained reservoir. The system can produce aerosols having a wide range of droplet sizes, depending upon central lumen diameter, with values of MMAD that range from 4 to 30 μm.
