Abstract
To decrease human error of the pericardiocentesis, we aimed to develop the pericardiocentesis assistance device. Purposes of this paper are to design of the pericardiocentesis assistance device. We proposed the new pericardiocentesis assistance device that needle was not used. The proposed device is able to aspiratethe fluid in pericardial space by cutting the pericardium using the cutter. To cut the pericardium, we designed the two type cutter that are the stress type cutter and the shear type cutter. As the result of two type cutter comparison experiment, the shear type cutter was able to cut the mock pericardium.
