Abstract
A fluid warming device for warming medical fluids, such as intravenously administered blood or saline solutions, is provided. The fluid warming device includes a conduit at least partially formed from a material with positive temperature coefficient properties. A supply of blood or other fluids may pass through the device and be heated to temperatures appropriate for administration to a patient.
Claims64
An apparatus comprising:
- a conduit for transferring a medical fluid, wherein the conduit comprises at least one portion configured to heat the medical fluid to approximately body temperature via a positive temperature coefficient material.
A fluid warming system comprising:
- a conduit adapted to be connected to a medical fluid supply, wherein the conduit comprises at least one portion configured to heat the medical fluid to approximately body temperature via a positive temperature coefficient material;
- and
- a controller operatively connected to the conduit, wherein the controller provides sufficient current to the positive temperature coefficient material to heat the medical fluid to approximately body temperature.
A method of warming a fluid comprising:
- transferring a fluid through a conduit comprising a positive temperature coefficient material;
- and
- applying sufficient current to the positive temperature coefficient material to heat the fluid to approximately body temperature.
A method of manufacturing a fluid warming device comprising:
- providing a conduit for transferring a medical fluid, wherein the conduit comprises at least one portion configured to heat the medical fluid to approximately body temperature via a positive temperature coefficient material.
A method of administering a warmed fluid to a patient comprising:
- transferring a fluid through a conduit comprising a positive temperature coefficient material such that the fluid is warmed to approximately body temperature;
- and
- administering the warmed fluid to the patient.
