Benefits of technology

[0015] It is an object of the present invention to provide a compact fluid dispenser for use in controllably dispensing fluid medicaments, such as, antibiotics, oncolytics, hormones, steroids, blood clotting agents, analgesics, and like medicinal agents from prefilled containers at a uniform rate.

Problems solved by technology

Such gravametric methods are cumbersome, imprecise and require bed confinement of the patient.
Certain classes of new pharmacologic agents possess a very narrow range of therapeutic effectiveness, for instance, too small a dose results in no effect, while too great a dose can result in a toxic reaction.
This cumbersome and tedious procedure creates an unacceptable probability of debilitating complications, particularly for the elderly and the infirm.

Embodiment Construction

[0127] Referring to the drawings and particularly to FIGS. 1 through 8, one embodiment of the dispensing apparatus of the present invention is there illustrated and generally designated by the numeral 34. As best seen in FIGS. 1 and 2, the apparatus here comprises a snap-together plastic outer housing 34 having a first, second and third portions 36, 38 and 40 respectively. Disposed within outer housing 34 is an inner, expandable housing 42 having a fluid reservoir 44 provided with an inlet 46 (FIG. 2) for permitting fluid flow into the fluid reservoir and an outlet 48 for permitting fluid flow from the fluid reservoir. Expandable housing 42, which can be constructed from a metal or plastic material, comprises a bellows structure having an expandable and compressible, accordion-like, annular-shaped sidewall 42a, the configuration of which is best seen in FIGS. 2 and 3. If the internal materials interface of the bellows structure and other fluid channels or surfaces are not sufficient...

Abstract

A compact fluid dispenser for use in controllably dispensing fluid medicaments, such as antibiotics, oncolytics, hormones, steroids, blood clotting agents, analgesics, and like medicinal agents from prefilled containers at a uniform rate. The dispenser uniquely includes a stored energy source that is provided in the form of a compressible-expandable elastomeric member of novel construction that provides the force necessary to continuously and uniformly expel fluid from the device reservoir. The device further includes a fluid flow control assembly that precisely controls the flow of the medicament solution to the patient.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates generally to fluid delivery devices. More particularly, the invention concerns an improved apparatus for infusing medicinal agents into an ambulatory patient at specific rates over extended periods of time, which apparatus includes a novel energy source, a novel fill means for filling the reservoir of the apparatus and a unique, adjustable, multichannel flow rate control means for precisely adjustably controlling the rate of fluid flow from the reservoir of the device. [0003] 2. Discussion of the Prior Art [0004] A number of different types of medicament dispensers for dispensing medicaments to ambulatory patients have been suggested. Many of the devices seek either to improve or to replace the traditional gravity flow and hypodermic syringe methods which have been the standard for delivery of liquid medicaments for many years. [0005] The prior art gravity flow methods typically involve...
