AI Technical Summary
In the existing nitrogen delivery system of cryogenic rehabilitation chambers, the connecting pipes are easily affected by the external ambient temperature, resulting in large temperature fluctuations and easy condensation of water droplets on the pipe surface, which affects the performance.
The delivery pipe assembly is equipped with an insulated outer shell, including an airbag insulation sleeve and a protective sleeve, forming an air insulation layer to prevent temperature changes and water droplet condensation.
Effective heat insulation reduces cooling consumption, prevents water condensation, and improves the stability and efficiency of nitrogen delivery.

Abstract
Claims
1. A nitrogen delivery system for a cryogenic rehabilitation pod for nitrogen delivery from a liquid nitrogen tank to a user rehabilitation pod, characterized by, The device includes a delivery pipe assembly having a first connection port that communicates with the nitrogen outlet of a liquid nitrogen tank and a second connection port that communicates with the nitrogen inlet of a user's rehabilitation chamber. The first connection port and the second connection port are connected through an internal channel of the delivery pipe assembly. It also includes a heat-insulating shell fitted onto the delivery pipe of the delivery pipe assembly, wherein the heat-insulating shell is configured to form an air insulation layer between the outer side of the delivery pipe and the outer side of the heat-insulating shell.
2. The nitrogen delivery system for the cryogenic rehabilitation chamber according to claim 1, characterized in that, The heat insulation shell includes an airbag heat insulation sleeve that is fitted onto the outside of the delivery pipe of the delivery pipe assembly along the pipe channel route between the first connection port and the second connection port. An air insulation layer is formed between the outer side and the inner side of the airbag insulation sleeve, surrounding the delivery pipe, and the end of the airbag insulation sleeve forms a sealed arrangement for the air insulation layer.
3. The nitrogen delivery system for a cryotherapy rehabilitation pod of claim 2, wherein, The end of the airbag heat insulation sleeve extends beyond the corresponding first and second connecting ports along the tube channel route between the first and second connecting ports.
