Fluid delivery device with bolus injection site

TLDR
In this paper, a conformable ullage made of yielding materials which uniquely conform to the shape of the elastomeric membrane was constructed for a low profile, laminate or layered construction.
Abstract
This invention is an apparatus (10) for accurately infusing fluids into a patient at specific rates over an extended period of time. The apparatus (10) is of a low profile, laminate or layered construction having a stored energy source in the form of a distended membrane (28), which in cooperation with the base (12) of the apparatus (10), defines one or more fluid reservoirs (20), each having a fluid inlet (22) and a fluid outlet (32). The apparatus further includes a novel conformable ullage made of yielding materials which uniquely conform to the shape of the elastomeric membrane (28) as the membrane (28) 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 (302) for controllably filling the reservoirs of the device in the field.

Measured dose dispensing device

Bernard Sams
TL;DR: In this paper, the authors present a device for dispensing a fluid from a container by means of the axial movement of a piston within the container under the influence of a plunger moved by the device, which device is adapted to receive the container on its forward end and to move the plunger axially forward towards or within the containers so as to dispense a selected amount of fluid from the container upon each actuation of the device.
