ABSTRACT:
A medicament container/dispenser assembly includes a substantially non-collapsible main body defining a chamber for containing the medicament in liquid form, the main body having an upper portion and a lower portion; an opening formed in the upper portion; a liquid impervious, gas permeable membrane secured to the upper portion of the main body in sealing relation to the opening; a rupturable exit port formed in the lower portion of the main body. The assembly may also include a second opening formed in the upper portion of the main body in spaced relation to the first-mentioned opening and an elastomeric, puncturable, sealing material secured to the upper portion of the main body in sealing relation to the second opening. In a further embodiment, a conduit may be positioned adjacent the membrane at the upper section of the main body, and may contain a blower for supplying forced air to the membrane through the conduit. A sensing device for sensing flow of the liquid medicament from the exit port and for controlling the blower in response thereto may be associated with the blower, in order to selectively activate the blower to maintain a substantially constant flow of medicament from the exit port.
