Liquid conductive cooling/heating device and method of use
A device for heating or cooling medical fluids to be administered to a patient is disclosed. The device comprises a hollow, cylindrical heat/cold exchanging body having external grooves for receiving flexible tubing, the body comprising conductive material for transferring heat or cold from the medical fluid flowing to the patient. A method of using the device is also disclosed.
1. A device for heating or cooling medical fluids flowing through flexible circular tubing for administration to a patient comprising a hand-held hollow cylindrical heat/cold exchanging body having an outer groove for accepting the flexible tubing, the groove and body comprising a metal conductive material for transferring heat or cold from the fluid flowing through the flexible tubing, the groove being capable of contacting about 66% of the circumference of the flexible tubing.
2. The device of claim 1 wherein the groove has sidewalls, a bottom and a lip.
3. The device of claim 1 wherein the device is made from a heat and cold conducting material.
4. The device of claim 3 wherein the heat and cold conducting material is aluminum.
5. The device of claim 1 wherein it is disposable.
6. The device of claim 1 wherein a heat-generating device is inserted with hollow cylindrical heat exchanging body.
7. The device of claim 6 wherein the device has a coating of heat absorbing material.
8. The device of claim 1 wherein the device has a coating of heat absorbing material.
9. The device of claim 1 wherein the outer groove has windings defining a spiral path around the outside of the heat exchanging body.
10. The device of claim 1 wherein the device has a first end and a second end, the first end and second having means for attaching the flexible tubing to securely fasten the tubing to the device.
11. A device for heating or cooling medical fluids flowing through a flexible circular tubing for administration to a patient comprising a hand-held hollow cylindrical heat/cold exchanging body having an inside wall and an outside wall and a width in between and a groove for accepting the flexible tubing, the groove being bored between the inside wall and outside wall of the heat/cold exchanging body.
12. The device of claim 11 wherein the groove has sides that contact about 100% of the circumference of the flexible tubing.
13. The device of claim 11 wherein the device is made from a metal heat and cold conducting material.
14. The device of claim 11 wherein the device is made from aluminum.
15. The device of claim 11 wherein it is disposable.
16. The device of claim 11 wherein a heat-generating device is inserted within the cylindrical heat or cold exchanging body.
17. The device of claim 11 wherein the heat-generating device is a light bulb and power source.
18. The device of claim 11 wherein the device has a first end and a second end, the first end and second end having means for attaching the flexible tubing to fasten securely the tubing to the device.
