Warming apparatus for infusion or flushing and application method thereof

Abstract

The invention relates to a warming apparatus for infusion or flushing and an application method thereof. A liquid container is inserted into an inner cavity of a warming apparatus, the warming apparatus is started, a microcontroller on a main control panel determines a temperature by virtue of a temperature sensor RT1 in a temperature measuring circuit, the microcontroller controls a heating circuit, when the temperature is smaller than a target temperature, the microcontroller transmits a signal to the heating circuit, a heating sheet begins to work, the microcontroller calculates the heatingpower, an upper heating sheet P10 and a lower heating sheet P11 are connected, the upper heating sheet P10 and the lower heating sheet P11 heat a heat conduction plate, and the heat conduction plateheats the liquid container; and when the temperature is approximate to the target temperature, the heating power is lower, after the temperature reaches the target temperature, the liquid container iskept at the target temperature until the infusion or flushing process is ended, the power of the warming apparatus is switched off, and the liquid container is taken out.

Description

technical field [0001] The present invention relates to a heating device for infusion or flushing and a method of using the same, and is especially applied to medical infusion, blood transfusion and clinical flushing. Background technique [0002] Infusion and flushing are important clinical treatment methods, especially for large-scale infusion of medicinal liquids, blood and intra-operative flushing. In actual use, infusion of medicinal liquids and intra-operative flushing fluids are often stored at room temperature or low temperature, and most blood is also Storage in cold storage, due to the low temperature of the input liquid, a large amount of input will lead to hypothermia, which will bring great harm to patients, such as surgical incision infection, cardiovascular adverse events, decreased coagulation function, prolonged anesthesia recovery time, prolonged hospitalization, etc. The fluid needs to be warmed during infusion. Therefore, warming during infusion is a com...

AI Technical Summary

Problems solved by technology

[0004] Incubator heating is one of the commonly used heating methods. It needs to place the liquid in the incubator to heat up in advance. The heating speed is slow and time-consuming. It is not suitable for emergency infusion or blood transfusion; the temperature of the heated liquid is not accurately displayed, and the temperature control is not accurate. ; Heating of static liquid, uneven heating may cause changes in the physical and chemical properties of the drug; poor heat preservation effect, more heat loss during infusion, and the infusion process is often heated first and then cooled; the heating speed is restricted by the initial temperature of the liquid, the lower the initial temperature, the higher the temperature. slower

[0005] Infusion tube heating is also a commonly used method at present. The infusion tube heating of patent No. ZL 200420036761.4 is mainly done by placing the pipeline into a heating device. This method has a very limited heating area of ​​the pipeline, and often the liquid in the pipeline has not been heated to the temperature and has already flowed. Downstream, so on this issue, some methods are to put the bag directly into the heating device, or set a very high temperature on the heating device to achieve the purpose of rapid heating, such as the patent number: ZL 03241419.6, but also because of this There is a safety hazard that plastic packaging or pipelines are melted by high temperature or chemical substances are precipitated

There are also solutions that coil the pipeline inside the heating device to increase the heating area, such as patent number: ZL 201520889903.X, patent number: ZL201730673014.4, and patent application number: ZL 201830317017.9. The heating area also makes the pipeline quite long. Too long pipeline is very easy to kink or hang on other items during use, and it is very inconvenient to coil the pipeline every time it is used, and the above Both solutions have slow heat conduction due to the specific thickness of the infusion line itself, and the use effect is not good

Moreover, the equipment is often relatively large, the handling is not flexible and the installation is also very cumbersome, and it is not easy to use
