Detailed Description
In the hospital treatment, there are three treatment divisions, and seven nursing divisions, which are the most important measures for the whole treatment and rehabilitation process. The infrared therapeutic apparatus is an indispensable important tool in nursing work. The infrared ray can penetrate through the clothes to act on the treatment part. Can penetrate through the skin to directly generate heat effect on muscles, subcutaneous tissues and the like. Accelerating blood circulation, increasing metabolism, reducing pain, increasing muscle relaxation, and generating massage effect. The infrared ray is mainly used for treating diseases because the infrared ray can mobilize the disease resistance of the human body from different levels. The existing infrared therapeutic apparatus is characterized in that an infrared head faces to a corresponding part of a human body, and the therapeutic apparatus is basically motionless in the process of physical therapy and has poor physical therapy effect. Meanwhile, some methods adopt thermal physiotherapy, and a heat source is directly arranged on human tissues.
Infrared therapy apparatus is facing to human corresponding part with infrared instrument head, in the middle of the physiotherapy process, the therapeutic instrument is motionless basically, because infrared ray of infrared therapy apparatus is through penetrating skin arrival appointed position, if not right always, lead to can penetrating at fixed skin, make this department skin extremely uncomfortable, and simultaneously, the wound equipotential of physiotherapy is also very limited, the physiotherapy effect is not good, simultaneously when using, the infrared that the tissue received is fixed, produce local overheat on the one hand, influence the physiotherapy effect on the contrary.
In order to solve the problems in the prior art, the embodiment discloses a rehabilitation robot capable of rotating around a fixed tissue and performing reciprocating motion, wherein the reciprocating motion refers to the fact that the distance between the head of an infrared instrument and the tissue can be changed ceaselessly.
