The invention discloses a multifunctional medical support, which comprises a column, the bottom of the column is welded with a base, a battery is installed at a front part of the inner cavity of the column, a support plate is welded to the top of the right side of the column, a fan is centrally mounted on the bottom of the support plate, and lights are installed on the bottom of the support plateat both sides of the fan, and a T-shaped chute for sliding a T-shaped moving seat is arranged in the middle of the inner cavity of the column. By extending and contracting the output end of an electric telescopic rod, and the height of the T-shaped moving seat can be adjusted, which is convenient to use. When the heating wire works, the heat is generated for warming the injured part, which is beneficial to the healing of the wound in the cold season, through the setting of a protective net cover. the direct contact between the heating resistance wire and the leg can be blocked, burns can be prevented, the fan works to provide cooling for leg injuries during the summer, sweat from running on the legs can be prevented, the sweat is not conducive to wound healing.
