When the length and the position of the heating connecting port 3-1 need to be adjusted, the connecting line 1-3 which is easy to tear can be torn according to the required length, so that the heating connecting pipe 3-4 can be prolonged, and the position of the heating connecting port 3-1 can be adjusted. Specifically, the method comprises the following steps. When the operation part is on the lower half of the body, the easily torn connecting line 1-3 can be completely torn to form a longer heating connecting pipe 3-4, and the heating connecting pipe 3-4 is turned to the side of the upper half of the body of the patient, so that the position of the heating connecting port 3-1 is adjusted to be far away from the operation area, and the limited space occupied by the wind heat insulating instrument for providing hot air flow for the air flow heating cavity 3 is avoided.

As shown in fig. 4, 5 and 6, the connecting portion 3-2 is linear, the heating chamber 3 is divided into a plurality of heating zones 3-5 by the linear connecting portion 3-2, and the heating zones 3-5 are all communicated with the heating connecting port 3-1. Therefore, during heating, hot air enters through the heating interface 3-1, enters into the plurality of heating zones 3-5 of the heating chamber 3 through the communicated heating interface 3-1 respectively, and then leaks out through micropores on the air temperature heating layer 2 at the lower layer of the heating chamber 3 to act on the upper body surface of a patient, thereby playing a role in heating and heat preservation. The arrangement of a plurality of heating zones 3-5 is to effectively divide the heating chamber 3 into blocks, so that the heating gas is more efficiently and uniformly distributed, and the body surface of the patient is heated more uniformly. In order to facilitate the effective discharge of the heated gas and facilitate the timely filling of the heated gas with stable temperature into the plurality of heating areas 3-5, a heated gas discharge port can be arranged at the opposite side of each heating area 3-5 far away from the heating connector 3-1, the heated gas discharge port cannot be too large, otherwise, the heated gas is discharged too fast, the heating cavity 3 cannot be effectively inflated, the proper positive pressure of the heating cavity 3 cannot be maintained, and the hot gas escape efficiency is reduced. The number of the heating gas discharge ports is preferably 1-2, and the diameter of each hole is preferably not more than 0.25 cm.
