[0065] It should be noted that the heating pipe 6 preferably adopts a spiral coil tube with elasticity and flexibility in the existing technology; the heating pipe 6 can be fixed by the binding strap 107, which is distributed in various positions of the upper cabin 1. Therefore, the heating pipe 6 can be arranged in different positions as needed to provide warm air for the wounded and sick.

[0066] In practice, the installation of a warm air inlet 5 and a heating pipe 6 can provide a better insulation environment for the wounded and sick, and provide more protection for field medical rescue.

[0067] In the embodiments provided by this utility model, such as Figure 1 As shown, the insulated chamber also includes an observation window 7 and a storage bag 8 installed on the upper chamber 1.

[0068] It should be noted that the observation window 7 is preferably connected to the upper cabin 1 by a zipper on three sides, and has a structure consistent with the sealing strip 105, so as to facilitate medical staff to observe the wounded and sick.

[0069] It should be noted that the storage bag 8 is preferably made of transparent material (such as plastic) and sewn onto the outside of the upper chamber 1 for temporary storage of testing equipment or other medical supplies.

[0070] In practice, the installation of observation windows 7 and storage bags 8 facilitates medical observation of the wounded and sick and the placement of medical supplies, thus providing convenience for field medical rescue.
