This invention prevents the danger of falling of body temperature by making the blood temperature similar to the body temperature in the injection of Ringer's solution fluid or blood transfusion, and also alleviates 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. 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 them PTC heating element's resistance specialty against the temperature as well as temperature sensor. |
