▎ 摘　　要

NOVELTY - The graphene knee pad has a knee pad (1) whose center is sewn with two layers of nitrile rubber (2). A graphene heating film (3) is provided between two layers. A surface of an inner side of the nitrilate rubber is adhered with an adhesive tape (4). A side of adhesive tape is arranged far away from graphene heating membrane. A sweat-absorbing cotton (5) is adhered on the side away from the adhesive tape. A power supply (12) is connected through a wire. The power supply is electrically connected to the temperature control switch (17). A heat sensor is connected to a temperature controller (17) that is connected to the heating membrane graphene. USE - Graphene knee pad for use by a patient with rheumatoid bone disease joint pain. ADVANTAGE - The graphene knee pad is sleeved on the knee, the skid-proof cotton can increase the friction force with the knee, so that the knee pad is stable when wearing. The graphene heating film can be kept on the specified temperature area, graphene the heating film for constant temperature heating of the knee. The knee inflammation caused by wearing knee pad for a long time can be avoided. The sweat-absorbing cotton can be quickly dried.
