Abstract

A flexible tubing device is used for intravenous infusion of medicine, particularly antibiotics, to all lumens of a multi-lumen central venous line catheter. The single input arm of the tubing device is connected to a source of medicine, and each of the several output legs of the tubing device are connected to different ports on the central venous line catheter. It allows a single input to be divided into a plurality of outputs. To allow this, the free end of the input arm has a female tube connector fitting while the free end of each of the output legs have a male tube connector fitting.

Claims

1. A tubing device for simultaneous fluid delivery to multi-lumen central venous catheters from a single IV line, comprising:

a single input arm and a plurality of output legs joined at a hub, the arm and the legs comprising respective tubes joined within the hub such that fluid input through said input arm will be divided at the hub so as to be output through each of the plurality of output legs;

a female tube connector fitting at the end of said single input arm opposite the hub; and

a male tube connector fitting at the end of each of said output legs opposite the hub,

whereby fluid delivered from the single IV line through the input arm may be divided so as to simultaneously flow through each of the output legs and thence to each of the lumens of a multi-lumen central venous catheter when in use.

2. The tubing device according to claim 1, wherein said female fitting includes a female Luer fitting and said male fitting includes a male Luer fitting.

3. The tubing device according to claim 1, wherein all the tubes and the fittings are sterile.

4. The tubing device according to claim 1, wherein said male and female tube connector fittings are integrally attached to the respective tubes.

5. The tubing device according to claim 1, wherein said tube connector fittings comprise an oppositely-gendered tube connector fitting integrally attached to the respective tubes and same gender adapters connected thereto to convert the integral female fittings to male fittings and vice versa.

6. The tubing device according to claim 1, wherein the plurality of output legs comprises two output legs, whereby the tubing device is connectable for use with a double-lumen central venous catheter.

7. The tubing device according to claim 1, wherein the plurality of output legs comprises three output legs, whereby the tubing device is connectable for use with a triple-lumen central venous catheter.

8. A method for administering antibiotic to patients having an indwelling multi-lumen central venous catheter and having a catheter-related bacteremia, by means of a tubing device in accordance with claim 1, comprising:

connecting the input arm of the tubing device to a source of antibiotic;

connecting each of the output legs of the tubing device to a respective one of the lumen of the multi-lumen central venous catheter; and

administering a single dose of antibiotic to the patient from the source of antibiotic, through the input arm and out of each of the output legs of the tubing device, and into the patient by means of each of the lumens of the multi-lumen central venous catheter.
