ABSTRACT
In the process of continuous renal replacement therapy (CRRT), various factors such as the temperature of replacement fluid, the flow of fluid and the circulation of blood in cardiopulmonary bypass, lead to the temperature of the blood injected back into the body is often lower than normal. It leads to the decrease of body temperature and the occurrence of hypothermia, which can be life-threatening in severe cases. In clinical practice, medical staff mostly reduces the occurrence of hypothermia in patients with CRRT by means of the heating device of the machine, the heating of the liquid temperature box for cardiopulmonary bypass, and the application of heating blankets, but the effect is not ideal. Therefore, medical staff of the department of critical care medicine of the Second Affiliated Hospital of Anhui Medical University designed a heating device and temperature control system for CRRT dialysis fluid bag, and obtained the National Invention Patent of China (ZL 2021 1 0334906.7). The device includes a heating and thermal insulation device and a temperature control system, wherein the heating and thermal insulation device is composed of the body of the heating dialysis fluid bag and the temperature control structure, which solves the problems of safe and efficient liquid heating and thermal insulation during the CRRT process. The temperature control system can display the dynamic state of the patient's body temperature, adjust the temperature of the dialysis fluid bag in time, and monitor the temperature of the blood transfusion in real time through the cooperation of the five modules of data collection, data handle, data analysis, regulation and display. This design is applied to CRRT, which can achieve precise control of body temperature of critically ill patients, and has certain clinical significance.
