Abstract

An electrically non-conductive back plate for supporting the back of a patient in a supine position comprises on its front face facing the back of the patient a pair or more of ECG electrodes capable of maintaining electrically conductive skin contact with the patient'"'"'s back. The pair of ECG electrodes is disposed at a sharp angle with the mean heart vector, in particular so as to form an angle β of about 45°±25° with the projection S of the patient'"'"'s spine on the back plate. Also disclosed is an ECG electrode for mounting in a recess of the back plate and an apparatus for treating cardiac arrest by compression of the sternum comprising the back plate.

Claims

1. A back plate for supporting the back of a patient in a supine position, the back plate for use in a system for treating cardiac arrest in a patient, the system including an apparatus for compressing the patient'"'"'s sternum against the back plate when the patient is in the supine position, the back plate comprising:

two or more ECG electrodes for maintaining contact with the patient'"'"'s back when the patient is in the supine position;

a front face facing the back of the patient when the patient is in the supine position; and

one or more recesses in the front face structured to be capable to receive therein at least a first one of the ECG electrodes at one of at least two alternative locations, for obtaining respectively alternative ECG traces of the patient between a second one of the ECG electrodes and the first ECG electrode in the two alternative locations.

2. The back plate of claim 1, in which

the first one of the recesses is structured such that the first ECG electrode is displaceable within the first recess along a direction.

3. The back plate of claim 1, in which

the back plate has two recesses, each capable of receiving therein the first ECG electrode.

4. The back plate of claim 1, in which

the back plate has a plurality of recesses, a number of the recesses being adjacent each other.

5. The back plate of claim 1, in which

the back plate has a plurality of recesses, a number of the recesses being adjacent each other along a direction.

6. The back plate of claim 1, in which

the back plate has a plurality of recesses, a number of the recesses being adjacent each other along two directions.

7. The back plate of claim 1, further comprising:

a spring located wholly within a first one the recesses for biasing the first ECG electrode towards the patient.

8. The back plate of claim 7, in which

the first ECG electrode can be compressed to be fully within the first recess against the resilient force of the spring.

9. The back plate of claim 7, in which

when in a non-load bearing state, the first electrode extends from the first recess by a short distance.

10. The back plate of claim 1, further comprising:

a manifold electrically connected with the first ECG electrode, and

in which the manifold is connected to an ECG monitoring unit.

11. The back plate of claim 10, in which

the manifold is connected with the ECG monitoring unit wirelessly.

12. The back plate of claim 10, in which

the manifold has a physical connection with the ECG monitoring unit.

13. The back plate of claim 10, in which

the system for treating cardiac arrest includes the manifold.
