This invention prevents the danger of falling body heat by making blood temperature similar to body temperature in Ringer's solution fluid or blood transfusion, and also lessens the patient's pain and improves the speed at which Ringer's solution fluid or blood enters the body. The warming device is much cheaper than previously released products, and small and light in weight, and allows blood or solution fluids to flow most effectively by allowing sufficient time for heat transfer as a pack type. Temperature of the heating element and of the element being warmed is equal by maximizing the contact area. The operation is convenient and sanitary in its single usage only. The inventive purpose has the methods of utilizing the temperature sensor in adjusting temperature by utilizing the PTC heating element's resistance specialty against the temperature as well as temperature sensor. |
