Abstract

A resuscitation device for assisting a rescuer in resuscitating a patient. A handheld computing/communication device may be configured for performing a non-resuscitation function during time periods when resuscitation is not required, the handheld device may be further configured to provide CPR prompts during time periods when used by a rescuer to assist in resuscitation, and a sensor may be provided to measure a parameter (e.g., chest acceleration) relevant to resuscitation. A CPR-assistance element may be configured to be applied to the patient and to communicate with the handheld computing/communication device.

Claims

1. A resuscitation device for assisting a rescuer in resuscitating a patient, comprising:

a handheld computing/communication device configured for performing a non-resuscitation function during time periods when resuscitation is not required;

the handheld device being further configured to provide CPR prompts during time periods when used by a rescuer to assist in resuscitation, and

the handheld device including a sensor configured to measure a parameter relevant to the performance of cardiac resuscitation.

2. The device of claim 1 wherein the device comprises circuitry for functioning as a cell phone.

3. The device of claim 1 wherein the device comprises circuitry for functioning as a personal digital assistant (PDA).

6. The device of claim 1 or 2 further comprising a dedicated button for activating a CPR prompting function.

7. The device of claim 1 wherein the sensor comprises a motion sensor and is configured to sense chest motion from which chest compression is estimated by the device.

9. The device of claim 2 wherein the cell phone is configured so that it may be placed between the rescuers hands and the patient'"'"'s chest, with the force delivered for chest compression being delivered through the cell phone.

10. The device of claim 1 further comprising circuit elements for providing spatial location.

11. The device of claim 10 wherein the circuit element for providing spatial location comprise GPS circuitry.

12. The device of claim 1 wherein the sensor comprises a sensor for making one or more of the following measurements:

ECG measurements, circulation measurements, ventilation measurements.

14. The device of claim 12 or 13 wherein a sensor for circulation measurements comprises one or more of the following:

pulse oximetry, ultrasound, impedance, heart or blood flow sounds.

15. The device of claim 12 or 13 wherein the sensor for ventilation measurements comprises a sensor for making one or more of the following measurements:

transthoracic impedance, airway pressure, or breathing sounds.

16. The device of claim 12 or 13 wherein the sensor comprises elements for making one or more of the following measurements:

ECG, oximetry, or transthoracic impedance measurements.

17. The device of claim 1 or 5 wherein the handheld computing/communication device has the capability of communicating with an EMS service.

18. The device of claim 17 wherein the handheld device has speaker phone capability to allow a lay rescuer to speak to the EMS service during a rescue.

29. The device of claim 1 or claim 4 wherein the device is configured to communicate with a therapy delivery device.

30. The device of claim 29 wherein the therapy delivery device comprises a defibrillator.

31. The device of claim 1 wherein the handheld computing/communication device comprises a structural element surrounding some portion of it to permit force to be applied through the device to the chest.

4. A resuscitation device for assisting a rescuer in resuscitating a patient, comprising:

a CPR-assistance element configured to be applied to the patient'"'"'s chest during resuscitation,

wherein the CPR-assistance element is configured to communicate with a handheld computing/communication device configured for performing a non-resuscitation function during time periods when resuscitation is not required.

5. The device of claim 4 wherein the CPR-assistance element communicates data relating to the patient to the handheld computing/communication device, which is further configured to provide CPR prompts based at least in part on the data received from the CPR-assistance element.

8. The device of claim 5 wherein the CPR-assistance element further comprises a motion sensor and is configured to be placed on the patient'"'"'s chest to sense chest motion from which chest compression may be estimated.

13. The device of claim 4 wherein the CPR-assistance element further comprises one or more sensors for making one or more of the following measurements:

ECG measurements, circulation measurements, ventilation measurements.

19. The device of claim 5 wherein the CPR-assistance element comprises circuitry for communicating wirelessly with the handheld computing/communication device.

20. The device of claim 5 wherein the CPR-assistance element is configured to automatically activate the handheld computing/communication device.

23. The device of claim 22 wherein adhesive is exposed by peeling away the release layer from the CPR-assistance element, and the exposed adhesive is configured to be used to adhere the element to the patient'"'"'s chest.

24. The device of claim 23 wherein electrodes are exposed in peeling away the release layer, and the electrodes and circuitry in the CPR-assistance element are configured to be used to detect ECG or make other measurements of the patient.

25. The device of claim 23 wherein the CPR-assistance element is configured to be positioned on the patient'"'"'s chest so that chest compression forces are applied to it by a rescuer.

26. The device of claim 5 wherein the handheld computing/communication device to which the CPR-assistance element communicates is a cell phone

27. The device of claim 4 wherein the CPR-assistance element is configured to be wearable by the patient.

28. The device of claim 4 wherein the CPR-assistance element is adhered by adhesive to the sternum during CPR, and chest compression forces are applied to it.

32. A resuscitation device for assisting a rescuer in resuscitating a patient or for training a rescuer to resuscitate a patient, comprising

a handheld device configured to be placed on the patient'"'"'s chest during resuscitation so that the user presses down on the device to convey compressive force to the patient'"'"'s chest;

an accelerometer supported within the device for measuring acceleration of the patient'"'"'s chest;

processing circuitry within the device for estimating chest displacement from measured acceleration and for delivering spoken prompts to the user to assist the user in delivering chest compressions,

a speaker for conveying the prompts to the user.

33. The device of claim 32 wherein the prompts inform the user either that he is delivering good compressions or that he should press harder.
