Abstract: Exoskeleton kinematic chain arranged to pivotally connect a first element to a second element, said first element comprising two pivot points A1 and B1 located at a distance A1B1, said second element comprising two pivot points A2 and B2 located at a distance A2B2. The exoskeleton kinematic chain comprises a first external link pivotally connected to the first element at the pivot point A1 and a first end link pivotally connected to the first external link at a pivot point D1, said pivot point D1 being located at a distance A1D1 by the pivot point A1. The exoskeleton kinematic chain comprises then a second external link pivotally connected to the second element at the pivot point A2, and a second end link pivotally connected to the second external link at a pivot point D2, said pivot point D2 being located at a distance A2D2 by the pivot point A2.

Abstract: An apparatus (1) for non-invasive mechanical ventilation comprises a fan (2) of Bi-level type, or BiPAP, for generating an air flow according to a succession of inspiration steps, or IPAP, and exhalation steps, or EPAP. The flow is conveyed in the aerial ducts of a patient (25) by means of a flexible tube (3) connected to a nasal mask (4). A flexible air reservoir (5) is provided pneumatically connected to the duct (3) and the nasal mask (4) in order to subtract from the inspiration flow a certain air amount before that it reaches the patient (25) at the beginning of an IPAP step. During the exhalation EPAP step, since the air flow pressure decreases automatically, there is the emptying at least partial of the flexible air reservoir (5), whereas the air exhaled by the patient exits through an opening (14) made on the nasal mask (4).
