  • Method for donning or doffing an artificial limb
    Patent number: 5658353
    Abstract: A method for donning or doffing a suction suspension prosthesis is disclosed. The air pressure between a residual limb and the distal end of a suction socket is electromechanically influenced to assist the donning or doffing of the suction socket. The air pressure is decreased to draw the residual limb into the suction socket and is increased to expel the residual limb from the suction socket. The method includes the use of a modified suction socket valve body, a low pressure vacuum pump, flexible tubing, and a non-greasy hypoallergenic lubricant.
