Abstract: Prosthetic socket is the only channel for load transfer between limb
stump and prosthetic limb, so its design is most important in meeting the
requirements of comfort and function. In order to improve comfort and
functionality of the upper-limb prosthetic socket, this paper presents a novel
design concept of the socket in which the areas and working time of compression
can be alternated in needs. A physical model of prosthesis socket with four
pressure-adjustable chambers driven by a vacuum pump was designed to form
pressure units in the socket to simulate its function in changing compression
loads.The effectiveness of the design was proved by experiments.
