Embodiment 1

[0026] Such as figure 1 As shown, the heating and heat preservation device is composed of an upper layer assembly 1 located on the upper layer and a lower layer assembly 2 located on the lower layer. The upper layer assembly 1 and the lower layer assembly 2 have a symmetrical structure, and the upper layer assembly 1 and the lower layer assembly 2 cooperate to form a complete infusion heating and heat preservation device. An infusion conduit inlet and outlet 3 is reserved at the interface where the upper layer assembly 1 and the lower layer assembly 2 cooperate. The overall cross-sectional view A-A of the heating and heat preservation device is as follows figure 2 shown. From figure 2 It can be seen that the upper layer assembly 1 and the lower layer assembly 2 are composed of a packaging shell 5 and a heating and heat preservation module 6 respectively. The circular channel 4 formed by the close cooperation of the upper and lower heating and heat preservation modules is...

Embodiment 2

[0029] The difference between the second embodiment and the first embodiment is that the structure of the elastic shell 10 of the heating and heat preservation module 6 is different. In this embodiment, the cross-sectional view of the cavity is a rectangle, which is made of shaped materials, such as metal materials, high-strength plastic materials, etc. For details, see Figure 6 . In actual use, the cavity structure of the heating and heat preservation module 6 can be changed according to actual conditions, and is not limited to oval or square.

Embodiment 3

[0031] The difference between Embodiment 3 and Embodiments 1 and 2 is that the inner surface of the heat conduction cover plate 7 of the heating and heat preservation module 6 in Embodiment 3 is processed with fin-shaped heat conduction ribs 11, and the fins are inserted into the solid-liquid phase change material , the main function is to enhance heat conduction, so that the infusion can be quickly heated and kept warm. For details, see Figure 7 .

Abstract

The invention relates to a medical infusion heating device based on a solid-liquid phase-change material and belongs to the field of medical auxiliary instruments. The medical infusion heating device comprises an upper structure and a lower structure, wherein each structure comprises a packaging housing and a heating and heat preservation module which are made of an insulation material, the heating and heat preservation module comprises a heat conduction cover plate, an elastic casing and the solid-liquid phase-change material, a cavity formed by the heat conduction cover plate and the elastic casing is filled with the solid-liquid phase-change material, channels for arranging an infusion conduit are uniformly formed in the outer surface of the heat conduction cover plate, bosses are arranged at two ends of the heat conduction cover plate and are matched with grooves in the packaging housing for positioning; the upper packaging housing and the lower packaging housing are fixed through mortise and tenon structures. The device heats blood or other infusion fluid flowing through from inside and enables the blood or the fluid to be at a temperature appropriate for a human body, so that discomfort of a patient due to the temperature difference between the infusion fluid and the human body is relieved, and one better infusion scheme is provided for modern medical treatment.

Description

technical field [0001] The invention relates to a medical transfusion heating device based on a solid-liquid phase change material, belonging to the field of medical auxiliary equipment. Background technique [0002] In the process of medical treatment, infusion and blood transfusion are very common means of treatment. In theory, the closer the temperature of the liquid or blood transfused into the human body is to the temperature of the human body, the better. However, in the current blood transfusion or infusion process of medical treatment, the temperature of the transfused liquid or blood is often lower than the patient's body temperature, which often causes the patient to experience physical discomfort, especially in the winter when the temperature is extremely low, field disaster relief, etc. In the case of extremely weak physical condition, the infusion of low-temperature liquid or blood will lead to the reduction of the local temperature of the patient's body and the...
