<p>A method and apparatus for the high volume manufacture of fluid infusion devices (14) which embody a self-contained stored-energy source for expelling fluids from the reservoir (30) of the device into an ambulatory patient at precisely controlled rates over extended periods of time. In accordance with the method of the invention, the base (16) and cover (22) infusion components of the devices of the invention are manufactured in injection molded arrays which comprise a cover (44) array which is superimposed over and connected to a base (46) array with the elastomeric membrane (27) being captured therebetween. The elastomeric membrane material (27) is continuously unrolled from a large roll of film-backed membrane material (72) which is rotatably mounted on a turret assembly (76) upon which a second back-up roll of elastomeric membrane material (74) is also mounted. The membrane is introduced into a novel tenter apparatus which controllably, biaxially stretches the membrane material. Following the stretching step, the membrane (72) is automatically cut and sealed between the cover components (22) and base (16) components of the cover (44) and base (46) arrays.</p> |
