Abstract
External defibrillators are provided that include a pulse sensor. These defibrillators may be used to treat a patient showing signs of possible cardiac arrest. ?
Claims38
An external defibrillator comprising
- defibrillator electrodes, and
- a piezoelectric polymer pulse sensor.
A medical device comprising
- a piezoelectric polymer pulse sensor;
- and
- a strap constructed to allow the pulse sensor to be attached to a patient's neck.
A medical device comprising
- a piezoelectric polymer pulse sensor, and
- a foam pad having a first surface to which the pulse sensor is attached, and a second surface constructed to be attached to a patient.
A method of treating a patient showing signs of possible cardiac arrest comprising:
- applying a piezoelectric pulse sensor to the patient;
- applying electrodes of a defibrillator to the patient;
- and
- using the pulse sensor to detect whether the patient has a pulse.
