The utility model belongs to the field of
medical instruments, and particularly relates to a
far infrared knee protection device which comprises a knee protection sleeve, a plurality of
far infrared heating films and an attaching
assembly. The kneecap sleeve comprises a supporting outer layer, an elastic
contact layer and a first
bandage; the plurality of
far infrared heating films are dispersedly distributed and attached to one surface, close to the supporting outer layer, of the elastic
contact layer; the two arc-shaped air bags are symmetrically distributed and arranged between the supporting outer layer and the far
infrared heating film, the guide
pipe is connected with the arc-shaped air bags and extends to the outer side of the supporting outer layer, the inflation
balloon is connected with the guide
pipe, and during use, the two arc-shaped air bags are located on the concave portions of the two sides of the knee respectively. The two arc-shaped air bags are properly expanded to enable the elastic
contact layer to deform to be attached to the concave parts on the two sides of the knee, so that proper adjustment can be conducted according to the knee shape of a user, the attaching degree with the knee part is improved, the
heat transfer efficiency is improved, gaps are reduced, the heat preservation performance is improved, and
knee joint rehabilitation treatment is facilitated.
