The invention relates to a structure and method of a pneumatic massage device. The main structure includes a wearable component for wrapping around the human body, a first inflatable member, a first outer inflatable member, a second inflatable member and a second outer The inflatable member, the plural inflatable tube bodies, at least one inflatable device and a control device, and the first outer inflatable member and the first inflatable member define at least a first exposed portion and a first abutting portion at a partial overlap, and the second The outer inflatable member and the second inflatable member define at least a second exposed portion and a second abutting portion at a partial overlap. When the control device drives the inflation device to repeatedly output gas through the inflation tube in a predetermined order, the first inflation member, the first outer inflation member, the second inflation member, and the second outer inflation member can be alternately inflated. Rotating and squeezing movements that produce angle changes, and highly simulating wavy massage gestures with overlapping hands to increase the effectiveness of abdominal massage.本發明為有關一種氣壓按摩器之結構及其方法，主要結構包括一供環繞於人體上之穿戴組件、一第一充氣件、一第一外充氣件、一第二充氣件及一第二外充氣件、複數充氣管體、至少一充氣裝置及一控制裝置，且第一外充氣件與第一充氣件於局部重疊處界定有至少一第一裸露部及一第一抵觸部，並第二外充氣件與第二充氣件於局部重疊處界定有至少一第二裸露部及一第二抵觸部。當控制裝置驅動充氣裝置，使其以預定順序重複的經由充氣管體輸出氣體時，第一充氣件、第一外充氣件、第二充氣件及第二外充氣件即可藉由交替充氣動作產生角度變化的旋轉擠壓動作，而高度模擬雙手交疊的波浪狀按摩手勢，以增加腹部按摩之效益。
