摘要：
An improved prosthetic device with a vacuum system for maintaining a negative pressure seal between the socket and the residual limb. The vacuum system includes a vacuum surge chamber which maintains seal vacuum and increases battery life. The system is small, lightweight, and concealable within the prosthetic device so that it neither impedes use of the device nor detracts from a cosmetically accurate limb.
