PROBLEM TO BE SOLVED: To provide an ultrasonic blood flow accelerator by which ultrasonic oscillation sufficiently acts on the action point of a human body, and also acts onto the cell unit of the human body to ease muscles, raise body temperature, and promote a blood flow for activation, and which can be easily manufactured and provided at a low cost.SOLUTION: The ultrasonic blood flow accelerator includes a head wherein an ultrasonic transducer is set inside a base with an action part. The action part with a flat top surface made an ultrasonic wave radiation surface, which is formed of a flexible material, is disposed on the base.COPYRIGHT: (C)2012,JPO&INPIT【課題】超音波振動が人体の作用部に充分に作用することはいうまでもなく人体の細胞単位にまで及んで筋肉をほぐし体温の上昇や血流を促進して活性化するとともに製造も簡単で安価に提供できる超音波血流促進器を提供する。【解決手段】作用部を有する基台の内側に超音波発振体を配置したヘッドを有し、基台に柔軟材により形成された平滑な頂面を超音波放射面を有する作用部を配置した。【選択図】図1
