Abstract

An elastomeric bladder stored energy type infusion apparatus which includes a unique fill assembly for use in controllably filling the fluid reservoir of the dispenser portion of the apparatus. The filling assembly includes a prefilled vial which is partially received within a novel adapter assembly that functions to operably couple the prefilled vial with the fluid dispenser subassembly of the apparatus. The body of the prefilled vial is surrounded by a protective covering until immediately prior to mating the assembly with the fluid delivery device.

Claims

1. A fluid delivery apparatus comprising:

(a) a fluid delivery assembly comprising;

(i) an elongated housing having walls defining an internal chamber, one of said walls having an outlet passageway;

(ii) a support assembly connected to said housing, said support assembly including;

a. an elongated body portion having a receiving chamber and an end wall portion having first and second fluid passageways each having an open end; and

b. a hollow cannula connected to said end wall portion and extending into said receiving chamber, said hollow cannula being in communication with said first fluid passageway formed in said end wall portion of said elongated body; and

(iii) an elongated tubular shaped elastomeric member connected proximate its ends to said support, said elastomeric member having a central portion disposed within said internal chamber of said housing and overlaying said open ends of said first and second fluid passageways, said central portion of said elastomeric member being distendable by fluid flowing through said first fluid passageway from a first position in proximity with said support to a second position; and

(b) a fill assembly interconnected with said fluid delivery assembly comprising;

(i) a container assembly including;

a. a container having a body portion, a fluid chamber, and first and second open ends;

b. closure means for sealably closing said first end of said container, said closure means being pierceable by said hollow cannula;

c. a plunger telescopically movable within said container from a first location proximate said open end to a second spaced apart location to cause fluid flow into said hollow cannula;

(ii) an adapter assembly receivable within said receiving chamber of said support assembly, said adapter assembly comprising a hollow housing having a first open end for telescopically receiving a part of said body portion of said container of said container assembly and including a second end.

2. An apparatus as defined in claim 1 in which said hollow housing further includes pusher means for engagement with said plunger of said container assembly to move said plunger within said container between first and second locations.

3. An apparatus as defined in claim 1 in which said fill assembly further includes a cover assembly comprising a cover having a first open end for telescopically receiving a part of said body portion of said container of said container assembly and a second end, said cover being removable from said container to expose said closure means.

4. A apparatus as defined in claim 1 in which said fluid delivery assembly further includes flow control means for controlling fluid flow between said second fluid passageway formed in said end wall portion of said support and said outlet passageway of said elongated housing.

5. An apparatus as defined in claim 1 in which said fluid delivery assembly further includes valve means for controlling fluid flow from said hollow cannula toward said first passageway formed in said end wall portion.

6. An apparatus as defined in claim 1 including alternate fill means for introducing fluid into said second passageway formed in said end wall portion.

7. A fluid delivery apparatus comprising:

(a) a fluid delivery assembly comprising;

(i) an elongated housing having walls defining an internal chamber, one of said walls having an outlet passageway;

(ii) a support assembly connected to said housing, said support assembly including;

a. an elongated body portion having a receiving chamber and an end wall portion having first and second fluid passageways each having an open end; and

b. a hollow cannula connected to said end wall portion and extending into said receiving chamber, said hollow cannula being in communication with said first fluid passageway formed in said end wall portion of said elongated body; and

(iii) an elongated tubular shaped elastomeric member connected proximate its ends to said support, said elastomeric member having a central portion disposed within said internal chamber of said housing and overlaying said open ends of said first and second fluid passageways, said central portion of said elastomeric member being distendable by fluid flowing through said first fluid passageway from a first position in proximity with said support to a second position; and

(b) a fill assembly interconnected with said fluid delivery assembly comprising;

(i) a container assembly including;

a. a container having a body portion, a fluid chamber, and first and second open ends;

b. closure means for sealably closing said first end of said container, said closure means comprising a pierceable septum pierceable by said hollow cannula;

c. a plunger telescopically movable within said container from a first location proximate said open end to a second spaced apart location to cause fluid flow into said hollow cannula;

d. pusher means for engagement with said plunger of said container assembly to move said plunger within said container between first and second locations; and

(ii) an adapter assembly receivable within said receiving chamber of said support assembly, said adapter assembly comprising a hollow housing having a first open end for telescopically receiving a part of said body portion of said container of said container assembly and including a second end.

8. A apparatus as defined in claim 7 in which said fluid delivery assembly further includes flow control means for controlling fluid flow between said second fluid passageway formed in said end wall portion of said support and said outlet passageway of said elongated housing.

9. An apparatus as defined in claim 8 in which said flow control means include flow rate control means for precisely controlling the rate of flow of fluid through said outlet passageway of said elongated housing.

10. An apparatus as defined in claim 9 in which said flow rate control means comprises a permeable porous member.

11. An apparatus as defined in claim 9 in which said flow rate control means comprises a rate control element having laser drilled apertures therethrough.

12. An apparatus as defined in claim 9 in which said fluid delivery assembly further includes valve means for controlling fluid flow from said hollow cannula toward said first passageway formed in said end wall portion.

13. An apparatus as defined in claim 9 including alternate fill means for introducing fluid into said second passageway formed in said end wall portion.

14. An apparatus as defined in claim 9 in which said container comprises a glass vial.

15. An apparatus as defined in claim 14 in which said closure means comprises a non-corable elastomeric septum and in which said container assembly further includes a clamping ring for crimping engagement with said glass vial to hold said elastomer septum in position.
