摘要:
The present invention relates to a lung function assessment system, a mechanical ventilator and method that allows simultaneously measurements of lung function and provides simultaneously mechanical ventilation to multiple subjects requiring one source of gas.
摘要:
A modular kit of complementary plethysmographic apparatus components including at least one tube, at least one termination device for closing an open extremity of the tube and first and second complementary coupling mechanisms formed on the tube and the termination device. The coupling mechanisms are adapted to provide sealing engagement between the tube and the termination device. The first and second complementary coupling mechanisms comprise a notched interface component adapted to fit into a corresponding mating gap component, such that a rotation of the two components with respect to each other, solidly locks the two components together while applying pressure onto a face seal between the two components.
摘要:
A mechanical ventilator for ventilating a patient employs an air displacement member mounted for oscillating motion in a chamber; preferably the chamber is semi-cylindrical and the air displacement member is a vane mounted for oscillating movement about an axis of rotation such that a free outer edge surface of the vane is maintained in closely spaced apart relationship with the interior wall of the chamber throughout the oscillating; the ventilator permits significant variation in the ventilation flow waveform.
