Abstract
A wearable defibrillator consists of a vest (or belt) which is worn by the patient. The device monitors the patient's ECG with sensing electrodes and can monitor other patient conditions and in appropriate cases can treat certain conditions. An accelerometer(s) in the wearable defibrillator can allow for the device to determine the position, movements, forces applied to the patient, and/or the device. The device can use a least one patient motion detector generating a signal indicative of patient activity. Analysis of the signal can be indicative of patient activity appropriate for treatment or indication of device condition.
Claims51
An externally wearable patient treatment device comprising:
- cardiac sensing electrodes connected to the device, said cardiac sensing electrodes adjacent said patient in proximity to said patient's skin;
- treatment elements connected to the device, said treatment elements adjacent said patient in proximity to said patient's skin;
- at least one patient motion detector connected to the device and generating a signal indicative of patient activity;
- at least one control to evaluate signals from said motion detector and said cardiac sensing electrodes to determine if said signal is indicative of patient activity appropriate for treatment;
- a treatment algorithm accelerating or delaying treatment based upon the output of said at least one patient motion detector;
- a patient response sensor which can delay treatment when operated by said patient;
- and
- a stimulator alarm providing patient stimulus after a cardiac condition is sensed and before a treatment is initiated,
- wherein said treatment algorithm initiates treatment when the output of said at least one patient motion detector indicates a lack of patient activity and no input is received from said patient response sensor.
A method of cardiac treatment of a patient including:
- providing an externally wearable patient treatment device including treatment elements adjacent said patient in proximity to said patient's skin, and at least one patient motion detector connected to the device and generating a signal indicative of patient activity;
- sensing a cardiac condition;
- treating a cardiac condition with the treatment elements worn by said patient on the device adjacent said patient;
- sensing patient activity with the at least one patient motion detector worn by said patient on the device;
- evaluating said sensed patient activity to determine treatment appropriate to said cardiac condition;
- providing an alarm to alert bystanders based upon post treatment detected patient activity;
- sensing a fall-off event of at least one of the treatment elements detaching from the device;
- and
- recording a patient body state during the fall-off event.
A method of cardiac treatment of a patient, comprising:
- providing an externally wearable patient treatment device including treatment elements adjacent said patient in proximity to said patient's skin, and at least one patient motion detector connected to the device and generating a signal indicative of patient activity;
- sensing a cardiac condition;
- treating a cardiac condition with the treatment elements worn by said patient on the device adjacent said patient;
- sensing patient activity with the at least one patient motion detector worn by said patient on the device;
- evaluating said sensed patient activity to determine treatment appropriate to said cardiac condition;
- providing an alarm to alert bystanders based upon post treatment detected patient activity;
- identifying device abuse;
- and
- notifying the patient of an abuse event.
