Abstract
A respiratory aid system has a device arranged for connection to a living creature in order to facilitate, support and/or control the respiration of the living creature. The device can be a ventilator or a neuroelectrical stimulation device. For faster and more efficient and more accurate respiratory aid the system contains a respiration detector, devised to pick up neuroelectrical signals from the living creature, identify respiration-related signals and send a control signal, related to the identified signals, to the device.
Claims19
A respiratory aid system comprising:
- a device adapted for connection to a living subject for assisting breathing by said subject;
- a sensor adapted for interaction with said subject for picking up neuroelectrical signals from said subject;
- an analyzer supplied with said neuroelectrical signals for identifying signals relating to respiration by said subject from said neuroelectrical signals;
- and
- a control signal generator, connected to said analyzer and to said device, for generating a control signal from said signals relating to respiration and for supplying said control signal to said device to control said device to assist said breathing.
A respiratory aid system comprising:
- a first device adapted for interacting with a respiration-related portion of a nervous system of a respiration subject for generating a control signal when a physiological attempt at breathing is sensed from said subject;
- and
- a second device, supplied with said control signal, adapted for interaction with said subject for providing respiratory aid to said subject dependent on said control signal.
A method for identifying a physiological attempt at respiration by a respirating subject, comprising the steps of:
- picking up neuroelectrical signals originating in a respiratory center of a respirating subject;
- filtering components out of said neuroelectrical signals related to respiration;
- identifying respiratory signals related to attempts at respiration from said signal components;
- and
- generating a triggering signal for triggering an inspiration phase dependent on said respiratory signals.
