Description

Technical Field

[0001] The utility model relates to the technical field of sports rehabilitation, in particular to an air wave massager capable of being externally connected with physical therapy equipment. Background Art

[0002] A Chinese utility model with the publication number CN222603831U proposes a "novel rehabilitation knee pad". An inner cavity is arranged in the knee pad, and an air bag and a heating patch are arranged in the inner cavity. The air bag is disposed on the inner side, and the shape of the heating patch is adapted to that of the air bag. Further, the air bag consists of an air bag air inlet passage, an air bag ring, an upper air bag passage and a lower air bag passage; the air bag air inlet passage communicates with the air bag ring, the upper air bag passages are disposed at both ends of the air bag ring and distributed on the left and right sides of the air bag air inlet passage, and the air bag air inlet passage is disposed at the lower end of the air bag ring and is in a shape of Chinese character "da" (meaning big). Gas is input by the air pump in the control box, flows through the air bag air inlet passage in sequence to enter the air bag ring, and then enters the left and right upper air bag passages and the lower air bag passage respectively from the air bag ring, wherein the lower air bag passage is in the shape of the Chinese character "da". When the pressure sensor in the control box reaches a set value, the air pump stops working, and the gas is discharged from the air vent in reverse.

[0003] This air bag massage function can massage muscles, relieve muscle soreness, appropriately activate the muscle level of elderly patients, and properly restore muscle mobility. It can relax the knees and promote blood circulation.

[0004] However, such a knee pad with pneumatic massage effect has a relatively fixed use mode, for example, it can only perform sports protection through the knee pad, perform pneumatic massage through the air bag, and perform hot compress through the electric heating patch, all of which rely on the structural components inherent in the knee pad itself.

[0005] Some knee pads with pneumatic massage effects, by virtue of their own existing storage batteries and control circuit modules, have also been developed into functional knee pads that can be externally connected with physical therapy equipment and output pulse current. For example, the electrode buckle of an external electrode wire can be connected to a physical therapy patch to perform massage and physical therapy on the cervical spine, lumbar spine, and various acupoints; it can be connected to a physical therapy handball to perform massage and physical therapy on the hand and dredge the hand meridians; it can be connected to a physical therapy waist belt to perform physical therapy and massage on the lumbar region, etc.

[0006] However, such functional knee pads need to be provided with both a charging interface for their own storage battery and an external interface for the function of connecting external physical therapy equipment, which needs to be improved. Contents of the Utility Model
