Abstract:
Sealed delivery unit 10 (shown in exploded format in FIG. 1A) contains medication 10M, and is formed by a generally flat member 10F pressed into selective engagement with an opposed shaped member 10S. Pumping chamber 12P, enclosed between the members generates a rupturing pressure in response to an external force applied by the user (indicated by arrow F shown in FIG. 1B). Enclosed Medication chamber 12M contains the medication to be delivered. Tunnel conduit 14 provides fluid communication between the chambers for rupturing the medication chamber in response to the rupturing pressure. Perimeter seal 16 extends around the pumping chamber and the medication chamber and the tunnel conduit. The perimeter seal is secure enough to withstand the internal rupturing pressure generated during delivery. Delivery port 18 with pull-away closure 18C (see FIG. 1C) delivers the medication out of medication chamber 12M. Rupture site 18S is proximate the delivery port. Rupture flap 18F produced by the rupturing at the rupture site, is connected to the pull-away closure. The flap projects outward permitting the user to grasp the pull-away the closure and open the delivery port for delivery of the medication.
