The present invention is applicable to the field of joint protection, and provides a joint protection device for
rheumatism clinical use, including an installation cylinder, and further including: mounting rings arranged on both sides of the installation cylinder, an elastic band fixedly connected between the mounting rings; a
protection mechanism arranged between the installation cylinder and the elastic band, including a fixed
pipe fixedly arranged on the side wall of the installation cylinder, one end of the elastic band far away from the telescopic
pipe is fixedly connected with a medicated pad, a heating component is arranged on the diversion
pipe, a liquid
medicine bag is fixedly connected to the
extrusion plate, the water outlet end of the liquid
medicine bag is fixedly communicated with the fixed pipe, a
piston column is fixedly connected to the
extrusion plate on one side of the liquid
medicine bag, one end of the
piston column is slidably penetrated and connected with the side wall of the installation cylinder, the end of the
piston column is hinged with a transmission rod, a buffer component is arranged between the transmission rod and the mounting ring, and a blood-activating component is arranged between the mounting ring and the elastic band. When the joint moves, the liquid medicine spreads and shunts through the
sponge pad, and while cooperating with the elastic band to achieve protection, the joint part is evenly coated with the medicine.
