We claim: 1. A fluid warming system comprising: a) a first fluid warming bag having (i) at least one fluid impermeable material that defines an inlet, an outlet, a top surface, a bottom surface, a fluid path extending between the inlet and the outlet, and (ii) a heating element integrated with the
We claim: 1. A fluid warming system comprising: a) a first fluid warming bag having (i) at least one fluid impermeable material that defines an inlet, an outlet, a top surface, a bottom surface, a fluid path extending between the inlet and the outlet, and (ii) a heating element integrated with the bag and positioned over a predetermined portion of the fluid path; and b) a warmer device having a slot and within the slot is a first actuating member, the first actuating member provides an electrical current to the heating element when the first fluid warming bag is inserted into the slot. 2. The fluid warming system of claim 1 wherein the heating element is integrated into or onto the bag by a method selected from the group consisting of printing, embossing, heat sealing, sonic sealing, adhesion, lithographing, or combinations thereof. 3. The fluid warming system of claim 1 wherein the fluid impermeable material permits thermal energy generated from the heating element to permeate into the fluid path. 4. The fluid warming system of claim 1 wherein fluid path has a design selected from the group consisting of a counter-flow, a serpentine, a random, and a straight method. 5. The fluid warming system of claim 1 wherein the fluid impermeable material is at least two impermeable materials. 6. The fluid warming system of claim 1 wherein the fluid impermeable material is a polymeric material. 7. The fluid warming system of claim 1 further comprising a sensor that measures the temperature of the fluid in the fluid path. 8. The fluid warming system of claim 7 wherein the sensor is attached to a second actuating member. 9. The fluid warming system of claim 8 wherein the second actuating member extends from a surface of the slot toward the other surface of the slot. 10. The fluid warming system of claim 1 wherein the second actuating member is a predetermined surface of the slot. 11. The fluid warming system of claim 1 wherein the first actuating member is a predetermined surface of the slot. 12. The fluid warming system of claim 1 wherein the first actuating member extends from a surface of the slot toward the other surface of the slot. 13. The fluid warming system of claim 1 wherein the inlet comprises a tube. 14. The fluid warming system of claim 13 wherein the tube is a stop mechanism to prevent over-insertion of the bag into the slot. 15. A fluid warming system of claim 1 wherein the fluid warming bag has a front edge having the inlet, a back edge that is opposite the front edge and two side edges; and at or near each side edge is a guide rail. 16. A fluid warming system of claim 1 further comprising a compression path. 17. A fluid warming system of claim 1 comprising a compression force apparatus that applies a compression force to the fluid in the fluid path. 18. A fluid warming system of claim 17 wherein the compression force apparatus is selected from the group consisting of the first actuation device that provides the electrical current to the heating element, a second actuation device that comprises a temperature sensor for the fluid in the fluid path, a third actuation device that just applies the compression force to the fluid in the fluid path, an electromagnetic system with at least the heating element, or combinations thereof. 19. A fluid warming system of claim 17 wherein the compression force is intermittent. 20. A fluid warming system of claim 17 wherein the compression force is constant. 21. A fluid warming bag comprising: a) at least one fluid impermeable material that defines an inlet, an outlet, a top surface, a bottom surface, a fluid path extending between the inlet and the outlet, and b) a heating element integrated with the bag and positioned over a predetermined portion of the fluid path. c) a compression force apparatus that applies a compression force to said fluid impermeable material, causing the fluid in the fluid path to flow. 22. The fluid warming bag of claim 21 further comprising a warmer device having a slot and within the slot is a first actuating member, the first actuating member provides an electrical current to the heating element when the first fluid warming bag is inserted into the slot. 23. The fluid warming bag of claim 21 wherein the heating element is integrated into or onto the bag by a method selected from the group consisting of printing, embossing, heat sealing, sonic sealing, adhesion, lithographing, a conductive material for the bag itself, or combinations thereof. 24. The fluid warming bag of claim 21 wherein the fluid impermeable material permits thermal energy generated from the heating element to permeate into the fluid path. 25. The fluid warming bag of claim 21 wherein fluid path has a design selected from the group consisting of a counter-flow, a serpentine, a random and a straight method. 26. The fluid warming bag of claim 21 wherein the fluid impermeable material is at least two impermeable materials. 27. The fluid warming bag of claim 21 wherein the fluid impermeable material is a polymeric material. 28. The fluid warming bag of claim 22 further comprising a sensor that measures the temperature of the fluid in the fluid path. 29. The fluid warming bag of claim 28 wherein the sensor is attached to a second actuating member. 30. The fluid warming bag of claim 28 wherein the second actuating member extends from a surface of the slot toward the other surface of the slot. 31. The fluid warming bag of claim 22 wherein the second actuating member is a predetermined surface of the slot. 32. The fluid warming bag of claim 22 wherein the first actuating member is a predetermined surface of the slot. 33. The fluid warming bag of claim 22 wherein the first actuating member extends from a surface of the slot toward the other surface of the slot. 34. The fluid warming bag of claim 22 wherein the inlet comprises a tube. 35. The fluid warming bag of claim 34 wherein the tube is a stop mechanism to prevent over-insertion of the bag into the slot. 36. A fluid warming bag of claim 21 wherein the fluid warming bag has a front edge having the inlet, a back edge that is opposite the front edge and two side edges; and at or near each side edge is a guide rail. 37. A fluid warming bag of claim 21 further comprising a compression path. 38. A fluid warming bag of claim 21 comprising a compression force apparatus that applies a compression force to the fluid in the fluid path. 39. A fluid warming bag of claim 21 wherein the compression force apparatus is selected from the group consisting of the first actuation device that provides the electrical current to the heating element, a second actuation device that comprises a temperature sensor for the fluid in the fluid path, a third actuation device that just applies the compression force to the fluid in the fluid path, an electromagnetic system with at least the heating element, or combinations thereof. 40. A fluid warming bag of claim 21 wherein the compression force is intermittent. 41. A fluid warming bag of claim 21 wherein the compression force is constant. 42.
