Abstract
A training apparatus (10) for the practice of puncturing blood vessels includes a model arm and an air-tight, liquid-tight compressible liquid container (19) and a two-way pressure threshold valve for transferring liquid between the container and the model arm. The model arm includes a core (14) of a solid material, a tight-fitting cover (32) of a penetrable material and at least one penetrable tube (31) provided between the core (14) and the cover (32), one end of the tube being connected to the liquid container (19) and the other end being sealed. The liquid container (19) is integrated into the model arm and disposed in such a manner so as to allow it to be compressed by establishing a pressure on a part of the surface of the model arm.
