Infusion tube heating device capable of realizing heat transfer by use of phase change

Abstract

The invention provides an infusion tube heating device capable of realizing heat transfer by use of a phase change. The device comprises a minitype refrigeration device, a heating device and a refrigerant hose tube, wherein the minitype refrigeration device comprises a minitype air-conditioning shell, a minitype fan, a refrigerant circulation pipeline, a minitype rotor compressor, a minitype coiled tube type evaporator, a condensing coiled tube, a capillary tube, an air inlet and an air outlet; the heating device comprises an infusion tube through hole, a hinge, a connection buckle, a heating layer and an insulating layer. The condensing coiled tube of the minitype refrigeration device is positioned in the heating layer of the heating device, and the minitype refrigeration device and the heating device are connected by virtue of the refrigerant hose tube; heat transfer is realized by virtue of self phase change of a refrigerant in a circulation process, i.e., the refrigerant absorbs heat of air in the evaporator, and releases heat in the condensing coiled tube, the heat is transferred to the infusion tube by virtue of a heat-conducting material in the heating layer, and heating of the infusion tube is realized. The infusion tube heating device has the characteristics of safety and reliability, energy conservation in operation, circulating utilization, convenience in operation and the like, and has a better application prospect.

Description

technical field [0001] The invention relates to a medical device, in particular to an infusion tube heating device for human body infusion in winter, which utilizes phase change to realize heat transfer. Background technique [0002] At present, infusion therapy is a common treatment method and measure for patients in hospitals. It is clinically used to replenish water, energy and infuse drugs for patients, which can quickly and effectively relieve and cure the disease. When people treat diseases with infusion in winter, due to the low temperature of the liquid medicine and the high temperature of the human body, new diseases often appear after the infusion. [0003] Most of the infusion devices currently used clinically do not have heating equipment. In winter, even if there are heating facilities indoors, the indoor temperature is difficult to exceed 20 degrees. In many places, the room temperature is around 16 degrees. Condition. In this way, when medical personnel disp...

Problems solved by technology

If it is heated during dispensing, it will delay time, and if the heating is not uniform, there will be quality problems in the liquid medicine, which will endanger the patient.

[0004] In order to solve the above problems, some infusion tube heating devices have been proposed. For example, the utility model patent "Infusion Tube Heating Device" with the publication number CN202505911. Although the method is easy to use and easy to operate, it can only be used once, causing a lot of waste, and when the use time is too long, the heat will not be released after the drug has reacted, the temperature of the drug solution cannot be guaranteed, and the safety and reliability are poor.

The utility model patent "A Heating Device for Infusion Tube" with the publication number CN203001611.U uses an electric heating plate with an S-shaped through hole inside to heat the medicinal liquid inside the infusion tube, which has the advantages of reusability and stable heating effect. However, this solution consumes more power and is not economical. Moreover, because the device is directly connected to the power supply, the temperature of the internal heating element is relatively high, and the safety performance is difficult to guarantee.
