ABSTRACT:
A below-knee prosthesis with a rigid, bowl-shaped outer shaft having a closed distal end, and with a flexible inner shaft which is fitted therein in a removable manner and which likewise has a closed distal end and also an air chamber which can be inflated via a valve. To improve the wearing comfort a) the inner shaft is designed as a soft silicone shaft which can be rolled over the stump of the prosthesis user and which completely surrounds the stump and bears against it; b) the air chamber of the inner shaft completely surrounds the distal end of the stump and extends only over a small partial length of the inner shaft; c) a connector plug is secured on the distal end of the inner shaft and communicates with the air chamber via a through-bore to permit air exchange; d) an insertion opening adapted to the connector plug and receiving it in a detachable manner is provided in the distal end of the outer shaft; and e) a flexible tube is connected to the insertion opening, and its tube end guided to the outside is connected to an exhaust valve and a pump.
