PROBLEM TO BE SOLVED: To provide a simple-structure and low-cost device whereby a massage or stretch of a deep part of a human body through which an artery passes, or a twist of a deep part blood vessel is easy and lasts long.SOLUTION: Because a deep part massage device has a shape wherein a lot of projections 2 project from a convex curved surface 1 or a convex spherical surface, a flesh part 14 of a human body is easily recessed by the convex curved surface or the convex spherical surface, and the lot of projections 2, and the deep part massage device can deeply bite into the human body, so that the deep part massage device expands and contracts a deep part of the human body to massage an artery itself by the reciprocating rotation of the convex curved surface or the convex spherical surface in a direction orthogonal to the projection direction. By performing the reciprocating rotation, a blood vessel itself is stretched when moving in a direction to pull the blood vessel. By rotating the whole device right and left, the operation to twist the blood vessel can be performed. The whole device can be linearly moved in xy two directions, or can be linearly moved in a direction crossing the reciprocating rotation direction.COPYRIGHT: (C)2013,JPO&INPIT【課題】動脈が通っている人体の深部のマッサージやストレッチや深部血管のねじりが容易で長続きし、かつ構造が簡単で安価な装置を実現する。【解決手段】凸曲面1や凸球面から多数の突起2が突出した形状をした深部マッサージ器であるから、凸曲面や凸球面と多数の突起2で人体の肉部14が容易に窪んで、人体の深くまで食い込むことができ、その結果、前記凸曲面や凸球面が突出方向と直角方向に往復回転することにより、人体の深くを伸縮させて動脈自体をマッサージできる。また、往復回転することで、血管を引っ張る方向に動く際に、血管自体がストレッチされる。装置全体を左右回転させることで、血管を捩じる動作も可能である。なお、装置全体をxy2方向に直線移動させたり、往復回転方向と交差する方向に直線移動させたりもできる。【選択図】図3
