[0002] During endoscopic surgeries such as laparoscopy, hysteroscopy, and transurethral resection of the prostate, the wound or cavity needs to be flushed with a certain pressure, temperature, and a large amount of sterile saline. Through continuous and large-scale saline flushing, wound secretions, blood accumulation, and necrotic tissue are gradually discharged, which can thoroughly improve the internal environment of the wound cavity, avoid possible contamination during the operation, and make the treatment simple and effective. The traditional flushing method requires medical personnel to manually hang the flushing liquid bag (usually a disposable 3000ml soft package) on a relatively high bracket (the common height is in the range of 2.7-2.8m): (1) There are certain height and physical limitations. Each surgical operation requires about 12-15 bags of 3000ml flushing liquid; (2) The flushing pressure is determined by the gravity of the flushing liquid (the height at which the flushing liquid bag is hung), which will decrease with the flushing time, and there is a risk of accidentally falling and hitting the patient; (3) The temperature of the flushing liquid is different from the body temperature, which will directly affect the patient's subjective feelings and may cause the patient's body spasms, especially in cold seasons. Therefore, an intelligent flushing fluid bag heating and pressurizing device is designed to overcome the above problems. Summary of the invention
