Respirator versatile multi-modal MRI compatible.

摘要

Respirator versatile multi-modal MRI compatible.; The present invention discloses an apparatus for supplying special gases NMR experiments with high precision and reproducibility. The special gas is introduced into a flexible bag (100) located within a sealed chamber (101). This gas passes to a pneumatic module (102) including a pressure sensor (103). In turn, the output of the pneumatic module is connected through a conductor (104) to an endotracheal tube (widely used with small experimental animals) or mask applied to the mouth of the subject under study. The module (105) controls the high-precision work system-real time, the electro-valves that handle the pneumatic module, the pressure in the lungs of the subject under study and the flow of gases supplied to said subject. This module is programmed via the control module and interface (106), which in turn may collect and store other physiological signals (107). Moreover, the module (105) can generate a fully controlled signal or may receive one or more external signals (108) to ensure the synchronism with NMR equipment and other equipment that are simultaneously measuring other physiological parameters of the subject under study. All modules) are fully compatible with MRI and can be placed inside the magnet or the magnetic shielding of this equipment (109).
