Document Type and Number:
Japanese Patent JP2001515371
Kind Code:
A
Abstract:
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 conforms 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 infusion cannula of the apparatus is connected to the base of the apparatus in a novel manner which permits expeditious subdermal delivery of liquid medicaments to the patient via a cannula which extends generally perpendicularly from the base.
