Abstract

A system for applying a lavage fluid to a surface, the system having a body configured to house a lavage fluid, an application member in fluid communication with the body, the application member being configured to dispense the lavage fluid, and a warming component configured to communicate with the body so as to transfer energy from the warming component to the body sufficient to warm the lavage fluid housed in the body.

First claim

What is claimed is:

1. A system for applying a lavage fluid to a surface, the system comprising:
a body configured to house a lavage fluid;
an application member in fluid communication with the body, wherein the application member is configured to dispense the lavage fluid; and
a warming component,
wherein the body comprises a plurality of inner-channels having an inner surface configured to contact a corresponding outer surface of the warming component, and
wherein the warming component comprises a warming material sufficient to warm the lavage fluid housed in the body using energy transferred from the warming material to the lavage fluid via the inner surface of the plurality of inner channels and the corresponding outer surface of the warming component.

2. The system according to claim 1 , wherein the warming component comprises a surrounding channel portion configured to surround at least a portion of the lavage fluid in the body.

3. The system according to claim 1 , wherein the warming material is configured to absorb energy.

4. The system according to claim 1 , wherein the warming material comprises an activatable warming material configured to provide heat upon activation.

5. The system according to claim 1 , wherein the warming material comprises a warming fluid.

6. The system according to claim 5 , wherein the warming fluid comprises heated water.

7. The system according to claim 5 , wherein the warming component comprises:
an input configured for the warming fluid to enter the warming component, and
an output configured for the warming fluid to exit the warming component.

8. The system according to claim 7 , wherein at least one of the input and the output comprises a restrictive feature selected from the group consisting of a one-way valve and an actuatable valve.

9. The system according to claim 1 , wherein the warming material is sufficient to warm the lavage fluid housed in the body to a temperature between about 32 and 43° C.

10. The system according to claim 9 , wherein the warming material is sufficient to warm the lavage fluid housed in the body to the temperature in a heating period of no more than five minutes.

11. The system according to claim 9 , wherein the system further comprises a temperature indicator configured to provide a signal when the lavage fluid has reached the temperature.

12. The system according to claim 11 , wherein the signal comprises a change in color of a temperature-sensitive material.

13. The system according to claim 11 , wherein the temperature indicator is comprised by at least one of the body and the warming component.

14. The system according to claim 1 , wherein the lavage fluid comprises an antiseptic agent and water, the antiseptic agent comprising iodine.
