[0024] The specific contents of the utility model are further explained in detail below in conjunction with the embodiments. DETAILED DESCRIPTION

[0025] It should be noted that, unless otherwise specified, all components in the present invention are components known in the prior art. For example, the control device is a known and commonly used control device.

[0026] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments, and all equivalent changes made on the basis of the technical solution of the present application fall within the protection scope of the present invention.

[0027] Example:

[0028] This embodiment provides an infusion heating assembly, such as Figure 1 and Figure 2 As shown, it includes a heating shell 1, in which a liquid infusion tube 2 is fixedly installed in the cavity of the heating shell 1. The liquid infusion tube 2 is a U-shaped tube structure with multiple windings. The liquid inlet and the liquid outlet of the liquid infusion tube 2 both penetrate the side wall of the corresponding position of the heating shell 1; the tube wall of the liquid infusion tube 2 is covered with a heating film 3, and the heating wires are evenly arranged on the heating film 3. The heating wires are potentially inside the heating film 3. The conventional arrangement method of the heating wires is selected according to actual needs.

[0029] A plug hole 4 is provided in the side wall of the heating shell 1 near the liquid outlet of the infusion tube 2. A plug 401 is provided in the plug hole 4. One end of the plug 401 can be connected to a power line, and the other end is connected to a heating wire.

[0030] When the above technical solution is actually used, the plug 401 is connected to the power cord, and the liquid in the infusion tube 2 is heated by electric heating. The U-shaped tube structure that is arranged in a circuitous manner for many times ensures that the liquid moves forward in a circuitous manner in the infusion tube, so that the liquid is heated evenly; by continuously energizing the heating wire on the heating film 3, it can continue to heat up, thereby ensuring that the liquid is continuously heated in the infusion tube. When it is heated to the required temperature, the power cord can be unplugged.

[0031] As a preferred solution of this implementation, the infusion heating assembly of the utility model also includes a control device 5, which is provided with a temperature control switch, and the plug 401 is connected to the heating wire through the temperature control switch in the control device 5; at least one temperature sensor connection point is provided on the infusion tube 2, and a temperature sensor can be installed at the corresponding connection point, and the temperature control switch can be connected to the temperature sensor; the heating film 3 is provided with a temperature sensor avoidance opening 301 corresponding to the number and position of the temperature sensor connection points.

[0032] The temperature sensor can be installed on the corresponding temperature sensor connection point through the corresponding temperature sensor avoidance port 301 to monitor the current temperature in real time. When the liquid is overheated, the temperature control switch is disconnected and automatically closed when heating is required, ensuring that the liquid can reach an appropriate temperature and realize automatic control.

[0033] As a preferred solution of this implementation, the infusion tube 2 includes an input section 201, an intermediate section 202 and an output section 203; the input section 201 is composed of a single pipe, the intermediate section 202 is composed of multiple pipes arranged side by side, and the output section 203 is composed of a single pipe; all pipes are connected through a connector 204, which is convenient for installation when the device needs to be used, and it is also convenient to disassemble the infusion tube 2 when the heating shell 1 and the connector 204 need to be maintained in the later stage.

[0034] Among them, for the subsequent cleaning, maintenance or disinfection of the heating shell 1 and the connecting piece 204, those skilled in the art are capable of maintaining the above components according to existing disinfection and maintenance methods.

[0035] It should be noted that the infusion tube 2 in the infusion heating assembly of the present application is a disposable consumable and will not be reused. The infusion heating assembly in the present application is mainly aimed at the infusion heating needs of patients in special occasions such as on-site first aid, extreme cold and extreme cold. In these occasions, due to the serious condition and injury of the patient, failure to heat the infusion liquid can easily cause discomfort and cramps in the patient, and even induce adverse reactions such as hypothermia that endanger life. Compared with protecting the life safety of the patient, the waste of resources caused by the infusion tube 2 of the infusion heating assembly of the present application as a disposable consumable is valuable. At the same time, whether it is necessary to use the infusion heating assembly for treatment or a lower-cost conventional treatment method in these occasions, medical staff can judge according to actual conditions.

[0036] Further preferably, the heating film 3 includes a first heating zone provided in the input section 201 , a second heating zone provided in the middle section 202 , and a third heating zone provided in the output section 203 , and the heating wires in different heating zones do not contact each other.

[0037] Temperature sensor connection points are provided on the input section 201 , the middle section 202 and the output section 203 of the infusion tube 2 , and temperature sensor avoidance openings 301 are provided at corresponding positions of the heating film 3 .

[0038] The control device 5 is provided with temperature control switches corresponding to the first heating zone, the second heating zone and the third heating zone one by one and capable of being opened and closed independently, and each temperature control switch can be connected to a temperature sensor on the corresponding heating zone.

[0039] The heating film is divided into three heating zones, and each heating zone is connected with a temperature control switch and a temperature sensor. Each temperature sensor detects the temperature of the corresponding heating zone in real time. When the temperature sensor detects that the temperature of the corresponding heating zone is too high, the temperature control switch corresponding to the heating zone is disconnected. After the temperature of the heating zone returns to normal, the corresponding temperature control switch is closed and reheated to achieve automatic control of the different zones.

[0040] At the same time, the temperature of the heating wire in each heating zone can be set according to actual needs, and the heating can be made more sufficient through step-by-step heating to prevent the occurrence of insufficient heating or local overheating.

[0041] As a preferred solution of this embodiment, the distribution density of the heating wires in the third heating zone is greater than the distribution density in the first heating zone or the second heating zone.

[0042] The distribution density of the heating wires is positively correlated with the heating efficiency. The density of the heating wires in the third heating zone is the largest. Even if the front section of the liquid is not heated sufficiently, it can ensure that the output liquid can reach the required temperature.

[0043] As a preferred solution of this implementation, a heat-conducting glue is provided between the heating film 3 and the infusion tube 2 to increase the heat conduction efficiency.

[0044] When the present invention is used, it can be connected in series to a universal disposable infusion set. Currently, the disposable infusion sets widely used in the market can be separated into two parts, the upper part is connected to the infusion bottle, and the lower part is the part with the infusion needle.

[0045] The infusion heating component of the present application is also connected to a commonly used disposable infusion set when in use, that is, the input section 201 of the infusion tube 2 is the liquid inflow end connected to the upper half of the infusion set, and the output section 203 of the infusion tube 2 is the liquid outflow end connected to the lower half of the infusion set, and then the power supply of the component is started to automatically heat the liquid at the outflow end to stabilize it at about 38°C, and the remaining usage steps are the same as conventional intravenous infusion.

[0046] In addition, for special infusion sets, the force exerted by the infusion heating assembly on the infusion bottle can be eliminated by fixing the infusion heating assembly of the present application on the bottle holder, so that there is no risk of the infusion tube falling out of the infusion bottle.
