Training simulator for mechanical ventilation

摘要

A diaphragm respiratory signal simulator is activated by skin voltage that is coupled to the simulator by many ways such as but not limited to a user sliding a finger over a conductive surface, the user sliding a finger over surfaces close to the conductive element, touch or sliding the finger over the ventilator screen. The conductive surface is electrically connected to a ring electrode at a distal part of a manikin's esophagus. The diaphragm respiratory signal simulator produces a synthetic diaphragm electrical signal that triggers a ventilator to deliver a supported breath, which is proportional to the strength of the generated signal. This process allows safe and successful training on the operations of NAVA mode of ventilation and catheter positioning.

1. An electrically passive device for simulating an Edi signal detected by a sensor array mounted on a catheter disposed in an esophagus of a manikin to trigger supported breath in NAVA mode of ventilation, comprising:
a signal actuator configured to couple a skin voltage of an operator based on an operator's moving contact on the signal actuator and generates a simulated Edi signal; a conductor that couples the simulated Edi signal from the signal actuator outside the manikin to inside the manikin; and a ring electrode coupled to the conductor and positioned inside the manikin so as to receive there-through the catheter that hosts the sensor array and collects-the simulated AEdi signal which in turn triggers supported breath in the NAVA mode.
