Fluid dispensing apparatus including mounting base for a plurality of fluid dispensing devices
| Details |
Inventors: Kriesel, Marshall S.;

An infusion apparatus for delivering beneficial agents, such as drugs to a patient at substantially a constant rate. The device uniquely includes a manifold system to which a plurality of elastomeric bladder type infusion devices are connected. Each infusion device includes an internally disposed functional substrate which carries the beneficial agent so that it can be mixed with the fluid as the fluid is being introduced into the device to distend the bladder to make it an energy source for controllably dispensing the solution mixture to the manifold system and thence to a patient. The manifold system includes control valves which permit fluid from selected infusion devices to be disposed from the apparatus. |

DETAILED DESCRIPTION It is an object of the present invention to provide an elastomeric bladder stored energy type infusion device which can be filled with a fluid such as a diluent and which during filling efficiently mixes the diluent with an additive such as a drug or other type of beneficial agent.
More particularly, it is an object of the invention to provide an infusion device of the aforementioned character which provides the opportunity to add to the diluent or other parenteral fluid being introduced into the device selected elements, chemical compounds and biologically active materials such as drugs, medicaments, biological agents, or other therapeutic agents (additives).
This addition is accomplished by removably affixing the selected additives to various forms of support structures which can be placed within the path of the fluid flowing through the device.
In this way, the delivery system of the invention can be safely rendered therapeutically active upon hydration of the additive with the selected parenteral fluid.
A primary object of the present invention, as more fully described in the paragraphs which follow, is to provide a novel manifold system to which several elastomeric bladder type infusion devices of the class described in Ser.
No.
08/053,723 can be operably interconnected.
Another object of the invention is to provide an apparatus which can be factory prefilled with a wide variety of medicinal fluid or one which can readily be filled in the field shortly prior to use.
Other objects of the invention are set forth in Ser.
No.
08/053,723 which is incorporated herein by reference.
By way of summary description, the novel apparatus of the present invention permits the controlled delivery from the apparatus of large volumes of the same or different fluids at controlled rates in accordance with a predetermined delivery regimen.
Although each of the individual fluid dispensers of the apparatus can be of varying reservoir volumes, by interconnecting a plurality of dispensers to the unique manifolding system of the invention, the controlled delivery over a given protocol of a substantial volume of fluids can readily be accomplished
