Fluid dispensing apparatus including mounting base for a plurality of fluid dispensing devices
First Claim
1. A fluid dispensing apparatus comprising:
- (a) a mounting base having first and second fluid inlets, a fluid outlet in communication with said fluid inlets, and valve means in communication with said fluid outlet for controlling fluid flow through said outlet; and
(b) at least two fluid dispensing devices connected to said mounting base, each said device comprising;
(i) a housing having walls defining an internal chamber and support means for supporting a stored energy source within said internal chamber, said housing also having connection means for connecting said housing to said mounting base, said support means having a fluid inlet and a fluid outlet in communication with one of said first and second fluid inlets of said base; and
(ii) filling means for introducing fluid into said fluid inlet of said support means; and
(iii) a generally tubular shaped elastomeric member connected proximate its ends to said support means, said elastomeric member having a central portion disposed within said internal chamber of said housing and overlaying said fluid inlet and said fluid outlet of said support means, said central portion of said elastomeric member being distendable by fluid flowing through said fluid inlet of said support means from a first position in proximity with said support means to second position.

Abstract
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.

17. A fluid dispensing apparatus comprising:
-
(a) a portable mounting base having; (i) a plurality of first and second fluid inlet passageways; (ii) at least one fluid outlet passageway in communication with said first and second fluid inlet passageways; (iii) base valve means in communication with said fluid inlet and outlet passageways for controlling fluid flow toward said fluid outlet passageway; and (iv) means for injecting fluid into said second fluid inlet passageways; and (b) a plurality of fluid dispensing devices connected to said base, each said device comprising; (i) a housing having walls defining an internal chamber and an elongated support member for supporting a stored energy source within said internal chamber, said housing also having connection means for connecting said housing to said mounting base, said support member having a fluid inlet chamber and a fluid outlet chamber in communication with said first fluid inlet passageways of said base; (ii) support member valve means carried by said support member for controling the flow of fluid through said fluid outlet chamber; (iii) filling means for introducing fluid into said fluid inlet chamber of said support member; (iv) a generally tubular shaped elastomeric member connected proximate its ends to said support means, said elastomeric member having a central portion disposed within said internal chamber of said housing and overlaying said fluid inlet and said fluid outlet of said support means, said central portion of said elastomeric member being distendable by fluid flowing through said fluid inlet of said support means from a first position in proximity with said support means to second position; and (v) adding means carried by said support means for adding an additive to fluid introduced by said filling means, said adding means comprising a beneficial agent disposed within said fluid inlet chamber of said support member. - View Dependent Claims (18, 19, 20)
