Abstract: A gymnastic machine (1) comprising a frame (10) supporting a first actuating device (40) provided with at least a pair of first levers (102)(104), each of which presents a respective implement (112)(116) suitable to act as user interface; a load unit (300) being provided in connection with the first levers (102) so as to dissipate power applied to each implement (112)(116) in a proportion definable at will; said load unit (300) being designed to maintain the first levers (102)(104) in phase opposition; second actuating devices (50) of magnetic kind being associated with the load unit (300) to bring and maintain the first levers (102)(104) at rest in a neutral position so as to prevent stopping conditions.

Abstract: A protection filter for hemodialysis lines includes a body provided with conduit coupling members, a first conduit being connected to a dialysis machine and the second conduit being directed towards a patient. The coupling members present generally coaxial internal holes opening at their ends, the holes mutually communicating within the interior of the body, within the body a filter element is present disposed between the holes of the coupling members. The body of the filter is in one piece, is homogeneous and is without joining lines between its various parts. The body incorporates the end edges of the filter element.
