    摘要: An apparatus for accurately infusing fluids into a patient at specific rates over an extended period of time. The apparatus is of a low profile, laminate or layered construction having a stored energy source in the form of a distendable membrane, which in cooperation with the base of the apparatus, defines one or more fluid reservoirs, each having a fluid inlet and a fluid outlet. The apparatus further includes, a novel, conformable ullage made of yieldable materials which uniquely conform to the shape of the elastomeric membrane as the membrane returns to its less distended configuration. This arrangement will satisfy even the most stringent medicament delivery tolerance requirements and will elegantly overcome the limitations of materials selection encountered in devices embodying solely a rigid ullage construction. Additionally, in one form of the invention, the apparatus includes a novel fill assembly for controllably filling the reservoirs of the device in the field.

    摘要: An apparatus for accurately infusing fluids into a patient at specific rates over an extended period of time. The apparatus is of a low profile, laminate construction having a stored energy source in the form of a distendable membrane, which in cooperation with the base of the apparatus defines one or more fluid reservoirs each having a fluid inlet and a fluid outlet. The apparatus further includes a novel, conformable ullage made of formable materials. The conformable ullage uniquely conforms to the shape of elastomeric membrane as the membrane returns to its less distend configuration and in so doing can move between a central chamber and a toroidal chamber formed in the cover of the apparatus. This arrangement will satisfy even the most stringent medicament delivery tolerance requirements and will elegantly overcome the limitations of materials selection encountered in devices embodying solely rigid ullage construction. Additionally, the infusion cannula of the apparatus is connected to the base in a novel manner which permits expeditious subdermal delivery to the patient via a cannula which extends generally perpendicularly relative to the base.

    摘要: An apparatus for accurately infusing fluids into a patient at specific rates over an extended period of time and the method for making same. The apparatus includes one or more dispensers of a low profile, laminate or layered construction each having a stored energy source in the form of a distendable membrane or an elastomeric cellular mass, which in cooperation with the base, defined a fluid chamber having a fluid inlet and a fluid outlet. The apparatus further includes, in lieu of a rigid ullage, a high novel, conformable ullage made of yieldable materials. The conformable ullage uniquely conforms to the shape of elastomeric membrane as the membrane returns to its less distended configuration. This arrangement will satisfy even the most stringent delivery tolerance requirements and will elegantly overcome the limitations of materials selection encountered in devices embodying the rigid ullage construction. Additionally, with the novel ullage construction, the ullage can be located either between the base and the fluid to be delivered, or alternatively, can be located between the elastomeric membrane and the fluid to be delivered. Further, a plurality of subreservoirs can be associated with a single ullage thereby making it possible to incorporate a wide variety of delivery profiles within a single device.
