The present invention relates to a method for detecting, warning and accelerating blood circulation function and a pressing device thereof. The device of detecting, warning and accelerating blood circulation function having a pressing protrusion part is employed to apply massage to the middle line portion at the backside of the lower leg of a human body, so as to detect, warn and accelerate the blood circulation of that portion. The pressing device of detecting, warning and accelerating blood circulation function includes: a main body provided with a base having at least a first base face and a second base face opposite to each other and a pressing protrusion part bulged from one portion of the first base face of the base of the main body, so as to facilitate massaging the middle line portion at the backside of the lower leg of the human body, thereby detecting, warning, and accelerating the blood circulation of that portion.一種檢測/警示/加速血液循環功能的方法及其按壓器,係藉具有按壓突部之檢測/警示/加速血液循環功能的按壓器,對人體小腿背面的中線部位施以按壓,以檢測/警示/加速該部位的血液循環。而檢測/警示/加速血液循環功能的按壓器係具有:本體,該本體具有基部,且該基部具有至少彼此相對的第一基面及第二基面;以及,按壓突部,該按壓突部係自本體之基部的第一基面之其中一個部位隆起,以便對人體小腿背面的中線部位按壓,以便以檢測/警示/加速該部位的血液循環。(20)‧‧‧檢測/警示/加速血液循環功能的按壓器(21)‧‧‧本體(22)‧‧‧基部(221)‧‧‧第一基面(222)‧‧‧第二基面(23)‧‧‧按壓突部
