A vacuum seal for installation in the hip socket. It is easy to install and is reliable in operation.
Structure and materials of manufacture
The seal consists of a rubber flat ring made of polymeric material and a metal nipple.
The new design of the vacuum seal has superior functional characteristics. The seal creates optimal discharge and reduces the pressure inside the prosthesis socket, as compared to the hydrostatic pressure inside the stump, which increases the stump unity with the prosthesis.
