| Abstract Scope |
In this work, a portable ventilator design for patients, including those with the Covid, is modeled. The material properties and the geometry of the ventilator components are selected based on the assembled ventilator prototype. First, the mechanical motions of the ventilator are optimized using an optimization code. Then the 3D model of the ventilator is constructed and simulated using finite element programs. Specifically, the respiratory airbag is focused for the coupled motion between the flexible body and fluid mechanics. The results show that the pressure and fluid velocity distributions of the respiratory airbag in the operation conditions can be optimized based on the patient’s breath needs. Additionally, a theoretical model for the rigid body dynamics is employed to compare against the finite element models. |
