Abstract: Provided is a spacer device (110) for delivery of drugs via a nebuliser device, the spacer device (110) comprising a bag (112) and a body (118) including inlet (114) and opposed outlet (116), the inlet (114) and opposed outlet (116) being provided on, and integral with, the body (118). The body (118) and bag (112) combine to form chamber (120) for receiving aerosolised medication. The inlet (114) and outlet (116) each are in the form of a port that is in fluid flow communication with the chamber (120). The inlet (114) and outlet (116) define, and are separated by, a broad V-formation formed as part of the body (118). The body (118) further includes an elliptical lower perimeter (118.1) defining flange (118.2), for demountably receiving bag (112).

Abstract: Provided is a Dry Powder Inhaler (DPI) arrangement comprising a DPI arranged in fluid communication with a spacer device (110) comprising a bag (112) and a body (118) including inlet (114) and opposed outlet (116), the inlet (114) and opposed outlet (116) being provided on, and integral with, the body (118). The body (118) and bag (112) combine to form chamber (120) for operatively receiving vaporised dry powder medication. The inlet (114) and outlet (116) each are in the form of a port that is in fluid flow communication with the chamber (120). The inlet (114) and outlet (116) define, and are separated by, a broad V-formation formed as part of the body (118). The body (118) further includes an elliptical lower perimeter (118.1) defining flange (118.2), for demountably receiving bag (112).

Abstract: The invention relates to a valveless spacer device for a metered dose inhaler (MDI), the spacer device comprising a body having an inlet and an outlet opposed from the inlet, a demountable, flexible bag attached to the body, the bag and body together defining a chamber, such that the inlet and outlet are in fluid flow communication with an interior of the chamber, wherein the inlet is configured to be connected to an MDI containing a drug to be inhaled and wherein the flexible bag, following actuation of the MDI, serves as a reservoir allowing for the formation of a cloud or mist of the drug therewithin which is then ready for inhalation, the flexible bag being configured to be at least partially deflatable and at least partially inflatable commensurate with a single breath and/or rebreathing.
