Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to a synchronous mobile infusion device for early postoperative walking exercise. Background Art

[0002] The current situation of laparoscopic surgery in our country is 156,820 laparoscopic surgeries per year; in China, there is such a type of disease, and nearly 1.5 million inguinal hernia surgeries are performed every year in China. Considering that the treatment of adult inguinal hernia mainly relies on surgery, and the number of patients in China is large and the surgery volume is huge; the time for exhaust after abdominal surgery varies for different patients and different conditions;

[0003] Because blood is prone to coagulate and form thrombus after surgical operations such as abdominal surgery, gynecological surgery, and thoracic surgery, once a thrombus is formed, it will cause local blood circulation disorders; if the embolism breaks off and embolizes in the lungs, the patient will be in danger; therefore, generally doctors will recommend that patients get out of bed and move as soon as possible after surgery. Early getting out of bed and moving by surgical patients helps to relieve the compression of muscles on veins, promote venous return, and reduce the chance of venous thrombosis; however, since patients need to receive intravenous infusion after surgery, they need accompanying personnel to accompany and hold the drip bottle / bag. But manually holding the drip bottle / bag requires holding it at a high place, which causes soreness in the arm after a long time. Although infusion stands are used, the infusion stands need to be manually pushed, which is extremely inconvenient to use. Summary of the Invention

When the temperature sensor detects that the local temperature exceeds the set value by ±2 °C, the exhaust fan 508 is started for forced convection heat dissipation, and at the same time, the heating power is reduced. The inner side of the cover plate 504 is provided with a double-layer heat insulation structure. The outer layer is a polycarbonate transparent protective cover, and the inner layer is filled with aerogel heat insulation material to ensure that the heat acts concentratedly on the liquid medicine area. The system presets a low-temperature infusion protection mode, and when the ambient temperature is lower than 15 °C, the constant temperature maintenance function is automatically activated to avoid liquid medicine crystallization or discomfort of the patient's body feeling.
