Abstract

A dual source parenteral infusion system includes a primary controller which controls the flow rate of a parenteral solution, a display which displays parameters associated with the delivery of a primary solution, and pushbuttons for entering solution delivery parameters into the controller. The primary controller communicates with a secondary infusion module which is programmed to deliver solution from a secondary source, with the flow rate being controlled by the primary controller. The secondary infusion module includes a display for displaying parameters associated with the delivery of the secondary solution and a drop detector, and mounts about a drip chamber for the secondary solution. The module may also include pushbuttons for entering fluid delivery parameters for the secondary solution into the module.

Claims

1. A dual source parenteral infusion system comprising:

a source of primary parenteral solution;

a source of secondary parenteral solution;

a primary administration set connected to said primary solution source, including a Y-connector and a section of common tubing;

a secondary administration set connected to said secondary solution source and to said Y-connector and including a secondary drip chamber;

a primary controller, including flow control means connected to said common tubing, means for detecting the delivery of primary solution, a display for displaying fluid delivery parameters, and means for programming said controller with fluid delivery parameters;

a secondary infusion module, separable from said primary controller and communicating with said primary controller, operating in conjunction with said secondary drip chamber, and adapted for connection with said secondary administration set, and including a display for displaying fluid delivery parameters of said secondary solution; and

wherein said secondary infusion module further includes means for communicating information concerning the operation of said secondary chamber to said primary controller.

2. The dual source parenteral infusion system of claim 1, wherein said secondary infusion module further includes means for programming said module with fluid delivery parameters of said secondary solution.

3. The dual source parenteral infusion system of claim 2, wherein said secondary infusion module further includes means for initiating the delivery of said secondary solution.

4. The dual source parenteral infusion system of claim 3, wherein said secondary infusion module further includes a drop detector connected to said secondary drip chamber.

5. The dual source parenteral infusion system of claim 4, wherein said module display includes means for displaying errors concerning the delivery of said secondary solution.

6. The dual source parenteral infusion system of claim 5, wherein said means for displaying errors displays errors concerning the operation of said secondary drip chamber.

7. The dual source parenteral infusion system of claim 6, wherein said primary controller display includes means for displaying flow-related errors.

8. The dual source parenteral infusion system of claim 3, wherein said secondary infusion module further includes means for selectively occluding said secondary administration set.

9. A dual source parenteral infusion system, including primary and secondary administration sets for administering solutions from primary and secondary solution sources, said administration sets being connected to a common tubing line, a fluid delivery rate controller connected to said common tubing line, said system further comprising:

a secondary infusion module adapted for connection to said secondary administration and communicating with said controller, said module including means for detecting the delivery of said secondary solution and means for displaying parameters associated with the delivery of said secondary solution; and

wherein said secondary administration set includes a secondary drip chamber, and wherein said detecting means includes a drop detector connected to said secondary drip chamber.

10. The dual source parenteral infusion system of claim 9, wherein said secondary infusion module includes means for programming said module with values associated with the delivery of said secondary solution.

11. The dual source parenteral infusion system of claim 10, wherein said secondary infusion module includes a unitary housing, and said housing includes said drop detector, said displaying means, and said programming means.

12. The dual source parenteral infusion system of claim 11, wherein said housing is mounted about said secondary drip chamber.

13. A dual source parenteral infusion system, including primary and secondary administration sets for administering solutions from primary and secondary solution sources, said administration sets being connected to a common tubing line, a fluid delivery rate controller connected to said common tubing line, said system further comprising:

a secondary infusion module associated with said secondary administration set and communicating with said controller, said module including means for detecting the delivery of said secondary solution and means for displaying parameters associated with the delivery of said secondary solution;

wherein said secondary infusion module includes means for programming said module with values associated with the delivery of said secondary solution;

wherein said secondary administration set includes a secondary drip chamber, and wherein said detecting means includes a drop detector connected to said secondary drip chamber; and

wherein said secondary infusion module further includes means for transmitting information about the operation of said secondary drip chamber to said controller, and wherein said controller includes means for transmitting information about the rate of fluid delivery to said secondary infusion module.

14. The dual source parenteral infusion system of claim 13, wherein said information about the operation of said secondary drip chamber includes drop detection and solution level information, and wherein said information about the rate of fluid delivery includes information as to the delivered dose of solution,

wherein said delivered dose information is displayed on said displaying means.

15. The dual source parenteral infusion system of claim 13, wherein said transmitting means of said secondary infusion module transmits delivery rate and dose information to said fluid delivery rate controller prior to commencement of secondary solution administration.
