Abstract

The invention presents techniques for making the operation of an automated external defibrillator easier to understand for an operator. The automated external defibrillator includes defibrillation electrodes packaged in a sealed, easy-to-open pouch. Visual cues such as instructive pictures show the operator how to open the pouch, retrieve the defibrillation electrodes and correctly position the electrodes on a patient'"'"'s chest.

Claims

1. A device comprising:

an external defibrillator;

a hermetically sealed pouch containing an electrode, wherein the electrode is an external defibrillation electrode for placement on a patient'"'"'s skin;

a lead wire that is connected to the electrode;

a connector connected to the lead wire for connecting the electrode to the defibrillator;

an anchor distinct from the connector-that fastens the pouch to the external defibrillator; and

a handle that is distinct from and attached to the pouch and that, when pulled away from the defibrillator, causes the pouch to be moved away from the anchor, and then to be pulled by both the handle and the anchor, and then to be torn open as a result of being pulled by he the handle and the anchor, for providing access to the electrode contained within the pouch, in which the pulling does not cause any force to be applied to the connector.

2. The device of claim 1, wherein the external defibrillator is a defibrillator-monitor.

3. The device of claim 2, further comprising:

a second external defibrillation electrode for placement on a patient'"'"'s skin.

4. The device of claim 1, wherein the anchor is substantially cylindrical.

5. The device of claim 1, wherein the anchor fastens the pouch to the external defibrillator non-permanently.

6. The device of claim 1, the external defibrillator comprising a mating member that receives the anchor.

7. The device of claim 1, the pouch further comprising:

a notch proximate to the anchor, the anchor on one side of the notch; and

wherein the handle is disposed on another side of the notch such that, when pulled, the handle moves away from the anchor and causes the pouch to tear at the notch.

8. The device of claim 1, the external defibrillator including a receptacle that receives the connector.

9. The device of claim 1, the external defibrillator including a lip that engages the pouch.

10. The device of claim 1, the pouch comprising an instructive picture that illustrates opening the pouch.

11. The device of claim 1, the pouch comprising an instructive picture that illustrates placement of the electrode on a patient.

12. The device of claim 1, wherein the handle is attached proximate a first end of the pouch and is oriented at a non-zero angle with respect to the first end of the pouch.

13. The device of claim 12, wherein the handle is arranged to be pulled diagonally across the pouch from the first end toward a second end opposite the first end.

14. The device of claim 1, wherein the anchor fastens the pouch to the external defibrillator such that the handle, when pulled, irreversibly tears the pouch and causes a first portion of the pouch to which the handle is attached to become unfastened from the external defibrillator while a second portion of the pouch remains fastened to the external defibrillator by the anchor.

15. The device of claim 1, wherein the handle is ring-shaped and operable to receive at least one finger of an operator inserted therethrough.

16. A device comprising:

a pouch containing a defibrillation electrode, the pouch comprising;

a ring-shaped handle that is distinct from and attached to the pouch;

a lead wire connected to the electrode;

a connector connected to the lead wire for connecting the electrode to the device; and

an anchor distinct from the connector that fastens the pouch to the device,

in which the ring-shaped handle, when pulled away from the device, causes the pouch to be moved away from the anchor, and then to be pulled by both the ring-shaped handle and the anchor, and then to be torn open as a result of being pulled by both the handle and the anchor, for providing access to the electrode contained within the pouch, in which the pulling does not cause any force to be applied to the connector.

17. The device of claim 16, the pouch further comprising a notch proximate to the handle, the pouch tearing at the notch when the handle is pulled.

18. The device of claim 17, wherein the handle is on one side of the notch, the pouch further comprising an anchor on another side of the notch.

19. The device of claim 17, further comprising a tear strip proximate to the notch, wherein causing the pouch to tear open comprises causing the pouch to tear along the tear strip.

20. The device of claim 16, wherein the handle is oriented to facilitate pulling in a defined direction.

21. The device of claim 16, the pouch further comprising an instructive picture that illustrates opening the pouch.

22. The device of claim 21, wherein the instructive picture includes a symbol representing the handle and wherein the symbol and the handle arc of the same color.

23. The device of claim 16, wherein the handle includes directional arrows.

24. The device of claim 16, the pouch comprising an instructive picture that illustrates placement of the defibrillation electrode on a patient.

25. The device of claim 16, the pouch containing a second defibrillation electrode, the pouch comprising an instructive picture that illustrates placement of the defibrillation electrodes on a patient.

26. The device of claim 16, wherein the ring-shaped handle is operable to receive at least one finger of an operator inserted therethrough.

27. A method comprising:

sealing a defibrillation electrode in a pouch;

connecting a lead wire to the electrode;

connecting the electrode to an external defibrillator with a connector connected to the lead wire;

fastening the pouch to the external defibrillator with an anchor distinct from the connector; and

constructing a ring-shaped handle on the pouch that is distinct from the pouch and that when pulled away from the defibrillator causes the pouch to be moved away from the anchor, and then to be pulled by both the ring-shaped handle and the anchor, and then to he torn open as a result of being pulled by both the handle and the anchor, for providing access to the electrode contained within the pouch, in which the pulling does not cause any force to be applied to the connector.

28. The method of claim 27, further comprising forming a notch in the pouch proximate to the handle, the pouch tearing at the notch when the handle is pulled.

29. The method of claim 28, wherein constructing a handle on the pouch comprises constructing a handle on one side of the notch, the method further comprising constructing the anchor on the pouch on another side of the notch.

30. The method of claim 29, wherein constructing a handle on the pouch comprises attaching the handle to the pouch.

31. The method of claim 29, further comprising printing an instructive picture on the pouch illustrating opening the pouch with the handle.

32. The method of claim 27, further comprising printing an instructive picture on the pouch illustrating placement of the electrode on a human figure.

33. The method of claim 27, further comprising:

passing the lead wire through a sealed entry point in the pouch.

34. The method of claim 27, wherein the ring-shaped handle is operable to receive at least one finger of an operator inserted therethrough.

35. A method comprising:

obtaining a pouch containing a defibrillation electrode hermetically sealed within the pouch; and

tearing open the pouch by pulling a ring-shaped handle that is distinct from and attached to the pouch, in a direction away from an extrnal defibrillator,

wherein a lead wire is connected to the electrode, a connector connected to the lead wire connects the electrode to the external defibrillator, and an anchor distinct from the connector fastens the pouch to the external defibrillator, and

wherein pulling the ring-shaped handle causes the pouch to be moved away from the anchor, and then to be pulled by oth the ring-shaped handle and the anchor, and then to be torn open as a result of being pulled by both the handle and the anchor, in which the pulling does not cause any force to be applied to the connector.

36. The method of claim 35, further comprising pulling the handle as shown in an instructive picture.

37. The method of claim 35, further comprising removing a liner from the defibrillation electrode.

38. The method of claim 35, further comprising placing the defibrillation electrode on the chest of a patient.

39. The method of claim 38, further comprising placing the defibrillation electrode on the chest of the patient as shown in an instructive picture.
