A jersey sheath drawing device for fitting contact prostheses, whereby an upper or lower limb amputee can easily put on his own prosthesis. The workload of hospital staff assigned to assisting amputees in specialized rehabilitation centres can also be reduced. The device comprises a bearing (10) designed to rest on the rim of the opening (2) at the end of the nest (1) of the prosthesis, a self-locking catch (12) for tightly gripping the jersey sheath (1B) across the whole or only a part of its cross-section, a pulling runner (11) sliding on a sliding frame (6) and controlling the locking catch (12). The pulling runner (11) can be moved manually by means of the handles (6A, 8) or electrically by means of an endless screw driven by a motor. The device allows both the prosthesis (1) to be guided towards the stump (1A) for fitting thereto and the sheath (1B) to be pulled tight while using only one hand, the device staying in place throughout the process. The handles (6A, 8) are ideally placed from an ergonomical point of view, both for the amputee himself and for a third party.
Apparatus for fitting a stump of a body member to a rest of a prosthesis having an open end for inserting the stump and a closed end against which the stump is adapted to bear, in which a jersey sheath is wrapped at least partly round the stump and threaded through an air exhaust opening at the closed end of the nest, said apparatus having a common support and comprising, mounted on the common support, traction means for applying traction force to the sheath for drawing the stump to the closed end of the nest, a bearing member bearing engageable with the nest in the immediate vicinity of the air exhaust opening for exerting a reaction force on the nest in response to the traction force applied by the traction means, and control means for controlling traction force applied by the traction means.
