Abstract
Disclosed herein is a base device with a pump device for applying pressure to a working fluid and a body contact device that can be detachably coupled to one another. A housing of the base device has a contact surface for the body contact device where the contact surface has a passage which can be closed by means of a closing member of a valve device. A spring is provided for applying spring force to move the closing member into a position that closes the passage. The body contact device has a pressure applicator, which can be acted upon by the working fluid, to apply pressure to the finger and a sealing element for creating a fluid connection with the base device. The body contact device has a deflecting means for deflecting the closing member against the spring force in the operating configuration.
