Abstract
A dispensing device and the method of making same for dispensing medicaments to a patient that includes a housing, a first assembly connected to the first end of the housing that includes a body portion, and a penetrating sub-assembly. The first assembly also includes a rate control chip of novel construction that is connected to the penetrating sub-assembly and functions to control the rate of flow of medicinal fluid to the patient. Disposed within the housing is a second assembly that includes a shuttle, a collapsible container carried by the shuttle and a plurality of variable force springs that function to thrust the collapsible container into penetrating engagement with the penetrating member of the penetrating assembly and then to collapse the collapsible container to deliver the medicinal fluid to the patient. Connected to the second end of the housing is a novel third assembly that includes an operating member that functions to controllably move the shuttle forwardly of the housing.
