Basic case. & Background of the Invention 1. Field of the Invention The present invention relates generally to a method and apparatus for heating a fluid flowing through a tube, and particularly to a method and apparatus for heating a patient infusion medium to be injected into a patient. To be more specific, the present invention relates to an improved method and device for heating a patient (human or animal) to provide a tube (or the rest of the ribbon). '' σ 2. General background of the present invention Hypothermia and its adverse side effects have been antibodies in the medical profession for many years. Medical experts understand that for the treatment of patients and victims of suffering from hypothermia and complications, warm liquids are needed, but there is no medical device in the emergency treatment of medical staff or in all hospital devices. Can produce warm blood or other venous fluids. The whole purpose of fluid warming is to be able to prevent and treat hypothermia. Hypothermia occurs when the patient's temperature is below 95 ° F or 35 ° C. Heating of intravenous fluids can increase body temperature. The stubborn cpR and other first aid measures are usually ineffective when the body temperature is below 95 ° F or 35 ° C. In hospitals, warming intravenous fluids can prevent other serious complications.

Description of the invention (2) Preventing and treating hypothermia ’is very important for the quality and cost of patient care. Current research has tracked the cost of complications caused by hypothermia, which includes (a) reducing medical effects, (b) prone to infection, (c) abnormal heart conditions, (d) respiratory arrest, (e ) Increased blood loss, (f) increased length of hospital stay, and (g) death. Previously existing systems used indirect heating of the infusion tubing to add patient infusion media injected into the patient's body, using additional emergency power or on-site power. Such systems use orbiting pipes to save space and minimize the heating area required for indirect heating elements. Some of these systems do not attempt fluid temperature at some point in the pipeline. Methods for heating fluids include the use of microwaves, or a fixedly heated intravenous injection bag ' that cools quickly when suspended from an intravenous rod. Therefore, there is a need for a low-cost device that is portable, disposable after use, and capable of preventing and treating hypothermia at the scene of first aid or hospital patients. The invention briefly summarizes a system for injecting a medium into a patient's body from a media container, which includes a tube, which surrounds or passes through the patient's infusion medium, and flows through an input terminal, which is received from the container to a The discharge end flows into the patient's body, an electrical conductor which is in contact with a part of the tubing or infusion medium, and an electronic circuit which heats this electrical conductor when activated. The electronic circuit contains a power source that heats the electrical conductor in a controlled way. [Electronic circuit] The temperature of the patient's infusion medium at the discharge end of the tube is measured, and at the same time, the body = temperature. If one of the temperatures is reached, the tube will be damaged. The temperature reached or the temperature of the patient infusion medium at the discharge end of the tubing may reach:
