ECG electrode and electrode support
View Patent ↗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.
1. An electrocardiogram (“ECG”) electrode for obtaining an ECG reading of a patient in a structure, comprising:
a front face;
a spring to be brought in contact with the structure for pressing the front face against the patient's skin; and
an electrically non-conductive support element integral with the electrode and at least a portion of the electrically non-conductive support element positioned between the electrode and the spring.
2. The ECG electrode of claim 1 , in which
the front face is provided with an electrical contact enhancing means.
3. The ECG electrode of claim 1 , further comprising:
a stem electrically coupled to the front face, and
a flexible wire coupled to the stem.
4. The ECG electrode of claim 3 , in which
the stem is formed integrally with the front face.
5. The ECG electrode of claim 3 , in which
the flexible wire is coupled to the structure.
6. The ECG electrode of claim 1 , in which
the front face is a portion of an electrode disk, and the electrically non-conductive support element is a rigid polymer material.
7. The ECG electrode of claim 1 , in which
the structure defines a recess, and the ECG electrode is located such that the spring is within the recess.
8. The ECG electrode of claim 7 , in which
the recess is structured such that the ECG electrode is displaceable within the recess along a direction.
9. The ECG electrode of claim 7 , in which
when the spring is in a non-load bearing state, the front face extends from the recess by a short distance.
