After marshaling in Aircraft X into [the] gate; I began to complete my post arrival duties. I hooked up the Ground Power Unit and received the all clear from the captain that he had power. After that I got the air hose from the jet bridge and started unrolling it to connect to the aircraft. Once I hooked the air hose up to the aircraft I began walking back towards the jet bridge to turn on the air. As I got to maybe about the midway point between the engine and jet bridge I felt a gust of wind that started blowing. I thought it was maybe just a big gust of wind that knocked me off balance. I then noticed that the air hose blowing toward me at a rapid pace. Before I could react or move; the air hose had become wrapped around my ankle. Once the air hose wrapped around my ankle it then snatched my leg and started pulling me violently underneath the aircraft. I tried to pull my leg from the air hose but as I pulled it became tighter. I did finally manage to get my leg from the grasp of the air hose. When I looked to see what happened; I noticed that a 777-300 aircraft had turned to the north towards the taxiway that runs parallel to Alpha taxiway and jet blasted [the] gate [area].
Ground personnel reported of an air hose that came loose from an aircraft due to jet exhaust from another aircraft. The air hose wrapped around his ankle and pulled him down.
