Description

{Heating apparatus for medical fluid}

TECHNICAL FIELD The present invention relates to a liquid heating apparatus, and more particularly, to a liquid heating apparatus that can heat a liquid by winding a tube through which liquid flows.

The fluid supply system is a system used to infuse fluid into the patient's circulatory system and is a part of medical treatment. Infusion involves the infusion of fluid, such as whole blood, blood components, saline, drugs, and the like.

In the case of an adult patient with low blood flow velocity, the amount of infused fluid is insignificant compared to the weight of the patient, so that the heating of the fluid is not generally performed, In the case of the patient, the blood flow velocity is considered to be a target of warming.

Generally, the injected fluid is warmed by a fluid warmer slightly away from the patient. After heating by a fluid warmer, the fluid is injected into the patient through the patient line. As the fluid flows through the patient line, the fluid loses heat due to radiation or convection heat loss. In order to prevent such heat loss, research was carried out to geometrically modify patient line piping. For example, it is possible to reduce the pipe diameter to improve the surface fluid flow rate, shorten the residence time of the liquid in the pipe, shorten the residence time in the pipe, and reduce heat loss due to radiation and convection.

Korean Registered Utility Model No. 20-0477709 (Registered on Jul. 5, 2015) discloses a liquid heating apparatus, comprising a pack body for providing a predetermined internal space, an outer surface formed on the outer surface of the pack body, And a heat storage material filled in the inner space of the main body, the heat storage material radiating the heat energy to heat the liquid solution; And a case having a receiving groove into which the heat accumulating pack is detachably received, and a heat insulating material provided in the receiving groove to surround the heat accumulating pack. According to the disclosed technology, the liquid can be warmed through the heat storage material made of the phase change material without a separate power supply.

Korean Patent Laid-Open No. 10-2007-0026373 (published on Mar. 03, 2007) discloses a fluid infusion device equipped with an insulation patient line pipe for preventing heat loss. According to the disclosed technique, there is a device for heating the fluid by transferring heat to the fluid, and an insulating tube for supplying the patient with warmed fluid, wherein the insulating tube is configured to allow the fluid to flow through the tube and lose a considerable amount of heat And a generally warm insulated component that prevents heat build-up.

The conventional liquid heating apparatus as described above has a considerable weight and a large volume due to the formation of a case or pack for warming the sap solution. Since the power supply apparatus is fixed, it is difficult to use it from the outside, It was difficult to use it immediately.
