Abstract

A closed system for flushing an IV site comprises a unitary reservoir assembly of a first fluid reservoir for containing a first flush fluid, a second fluid reservoir for containing a second flush fluid, a tubing array for connecting the first and the second reservoirs to an IV site comprising a common tube having a connector on one end thereof for connection to the site, and mounted in a housing having depressible panels for selectively controlling the flow of a fluid from each of the first and the second reservoirs.

Claims

1. A closed system for flushing an IV infusion site comprising:

a box-like housing having a chamber;

a unitary pliable reservoir assembly disposed in said chamber and comprising a first fluid reservoir for containing a first flush fluid, a second fluid reservoir for containing a second flush fluid, said first and said second reservoirs are disposed in side by side relation and one of said reservoirs is divided into two interconnected chambers;

a tubing array connecting said first and said second reservoirs together and for connecting to an IV infusion site comprising a common tube having means on one end thereof for connection to said site, and means on the other end thereof for controlling communication of each of said first and said second reservoirs via said common tube to said site; and

means for selectively positively collapsing each of said first and said second reservoirs for controlling the flow of a fluid therefrom.

2. A closed system according to claim 1 wherein said common tube has coupling means for coupling an IV infusion device thereto.

3. A closed system according to claim 2 wherein said means for selectively positively collapsing each of said first and said second reservoirs comprises separate pivoting wall means for collapsing each of said reservoirs.

4. A closed system according to claim 3 wherein:

said housing has a triangular shape in cross section; and

means for latching said pivoting walls in a collapsed position.

5. A closed system according to claim 1 wherein said means for collapsing said reservoirs comprises pivoting wall means contacting said reservoirs and responsive to pressure for biasing said reservoirs to a collapsed condition.

6. A closed system according to claim 5 wherein:

said housing has a triangular shape in cross section; and

means for latching said pivoting walls in a selected one of a partially collapsed and a fully collapsed position.

7. A closed system according to claim 1 further comprising:

an infusion device comprising a generally spherical shell;

an inflatable bladder in said spherical shell; and

tubing means connected to said bladder and to said tubing array for conveying a fluid in said bladder to the IV infusion site.

8. A closed system for flushing an IV site comprising:

a box-like housing having a chamber;

a unitary pliable reservoir assembly disposed in said chamber and comprising a first fluid reservoir for containing a first flush fluid, a second fluid reservoir for containing a second flush fluid;

a tubing array connecting said first and second reservoirs together and for connecting to an IV infusion site comprising a common tube having means on one end thereof for connection to said site, and means on the other end thereof for controlling communication of each of said first and said second reservoirs via said common tube to said site; and

means for selectively positively collapsing each of said first and second reservoirs for controlling the flow of a fluid therefrom wherein said means for collapsing said reservoir comprises separate pivoting wall means contacting each of said reservoirs and responsive to pressure for biasing said reservoirs to a collapsed condition.

9. A closed system according to claim 8, wherein:

said first and said second reservoirs are disposed in side by side relation and one of said reservoirs is divided into two interconnected chambers, and said housing has a triangular shape in cross section; and

further comprising means for latching said pivoting walls in a collapsed position.

10. A closed system according to claim 9 wherein:

said housing has a triangular shape in cross section.

11. A closed system according to claim 8 wherein:

said housing has a triangular shape in cross section; and

means for latching said pivoting walls in a collapsed position.

12. A closed system according to claim 8 wherein said common tube includes coupling for coupling an IV infuser thereto.

13. A closed system according to claim 8 further comprising:

an infusion device comprising a generally spherical shell;

an inflatable bladder in said spherical shell; and

tubing means connected to said bladder and to said tubing array for conveying a fluid in said bladder to the IV infusion site.

14. A closed IV site flushing system for flushing an IV infusion site with multiple fluids comprising in combination:

a housing having walls defining a wedge shaped chamber;

a unitary reservoir construction comprising a first pliable fluid reservoir having first and second fluid chambers for containing separate charges of a first flush fluid, and a second pliable fluid reservoir for containing a second flush fluid disposed in said housing;

a tubing array connected to said first and said second fluid reservoirs and having connecting means on an end thereof for connecting to an IV infusion site; and

housing means for selectively engaging and separately collapsing said first and said second reservoirs for controlling the flow of a fluid from each of said first and said second reservoirs to said infusion site.

15. A closed system according to claim 14 wherein said tubing array has coupling means for coupling an IV infusion device thereto.

16. A closed system according to claim 15 wherein said housing means for collapsing said reservoirs comprises pivoting wall means contacting said reservoirs and responsive to pressure for biasing said reservoirs to a selected collapsed condition.

17. A closed system according to claim 16 wherein:

said housing has a triangular shape in cross section; and

means for latching said pivoting walls in a selected one of a partially and a fully collapsed position.

18. A closed system according to claim 14 further comprising:

an infusion device comprising a generally spherical shell;

an inflatable bladder in said spherical shell; and

tubing means connected to said bladder and to said tubing array for conveying a fluid in said bladder to the IV infusion site.

19. A closed system according to claim 18 wherein said housing means for collapsing said reservoirs comprises pivoting wall means contacting said reservoirs and responsive to pressure for biasing said reservoirs to a collapsed condition.
