Description
Technical Field
The utility model belongs to the field of medical equipment, relate to infusion temperature control, concretely relates to portable infusion temperature regulating device.
Background
The normal temperature of human body is generally 36.3-37.2 deg.C (oral cavity) and 36.1-37 deg.C (axilla), while some drugs or products need to be refrigerated at 0-4 deg.C during storage. When the body fluid loss of the human body needs fluid replacement, the fluid is generally required to be heated and is input into the veins of the human body after the temperature reaches the temperature of about the normal body temperature. However, in some emergency situations, such as when a large amount of fluid loss of a human body needs to be supplemented or some medicines need to be infused in a large dose, the heating is not in time, and the medicines need to be directly infused into the human body through veins at a refrigeration temperature. However, when large amounts of blood or some medical liquids are infused at refrigerated temperatures, there are serious consequences that cause hypothermia or low temperature shock in the human body due to the hypothermia of the infused liquid. Even when rescue is performed in the field, the body of the sick and wounded to be rescued often has hypothermia due to the low temperature of the field environment and/or self-injury. The consequences of this risk are even more exacerbated and even life-threatening to the injured person if an emergency infusion of large doses of liquid requiring refrigeration is required.
In the prior art, there are three solutions to the above problem, one of which is to use an external fluid heating pipeline type fluid heater, which is generally used in medical institutions and needs to use a fixed ac power source as a heating source. And temperature control accuracy is relatively poor, the system is heavy, long installation time is required, portability is poor, and emergency pre-hospital rescue cannot be carried out.
And secondly, the liquid to be infused is insulated by adopting a mode of heating, insulating and storing in the insulation box, so that the liquid has a certain temperature when being infused into a human body. If the mode is applied to emergency situations such as field rescue, a larger box body and a certain heat-insulating heat source are needed, so that the system is complex and heavy.

The self-heating device is generally filled and packaged by a heating material at one time, and is mixed to generate heat when in use. The heating temperature is not controllable, the heating time is short, the shelf life of the disposable material is short, the use waste rate is large, and the efficiency-cost ratio is too low.
