1. A product dispensing system comprising:
- a calibrated nebulizer having a nebulizer jet;
a mouthpiece;
means for sourcing compressed air;
a manifold for distributing the compressed air in at least one direction;
a port;
a nebulizer accommodation means which is accessed by the port;
a valve means for controlling the manifold and thereby the flow of compressed air to the port; and
a length of tube linking the manifold and the port, the internal volume of which, from the manifold outlet to the nebulizer jet, is less than 0.7 ml.

Abstract
A product dispensing system comprises a calibrated nebulizer having a nebulizer jet, mouthpiece, means for sourcing compressed air, a manifold for distributing the source of compressed air in at least one direction, a nebulizer accommodation means which is accessed by port, and a valve means for controlling the manifold and thereby the flow of compressed air to the port. The manifold and the port are linked by a length of tube, wherein the internal volume of the tube from the manifold outlet to the nebulizer jet is less than 0.7 ml.

23. A product dispensing system comprising:
-
a calibrated nebulizer having a nebulizer jet;
a mouthpiece;
means for sourcing compressed air;
a manifold of distributing the compressed air in at least one direction;
a port;
a nebulizer accommodation means which is accessed by the port;
a valve means for controlling the manifold and thereby the flow of compressed air to the port;
a length of tube linking the manifold and the port;
a pressure sensor for detecting a drop in pressure in the apparatus in response to a patient'"'"'s breathing to indicate the rate of inhalation of the patient; and
means for determining the dose dispensed, the dose being determined on the basis of the output rate of the medicament of the nebulizer, and the duration of the delivery of the medicament, the dose determining means serving to adjust the value of the output rate on the basis of the rate of inhalation of the patient detected by the pressure sensor. - View Dependent Claims (24)
