Abstract

The invention concerns a device for acquiring electric signals of the human body from a patient'"'"'s heart (P, 2), comprising at least two independent connection elements (8, 9; 80, 90) comprising respectively supports (4) provided each with electrodes (3) connected by an electric cable (5, 5′) with parallel strands which is connected to an input (10, 11) of an acquisition card (6) to receive and transmit free of electromagnetic interference electric signals derived from the electrodes (3) to a central unit (7) for data processing, analysing and editing.

Claims

1. A device for acquiring electric signals from the human body from the heart of a patient (P,2), characterized in that it comprises at least two independent connection elements (8, 9;

80, 90) respectively having supports (4), each one provided with electrodes (3) connected via a parallel-strands electric cable (5, 5′

) which is connected to an input (10, 11) of an acquisition card (6) for receiving and transmitting, without electromagnetic interference, the electric signals coming from the electrodes (3) to a central processing unit (7) for processing, analyzing and printing out data.

2. The device for acquiring electric signals as claimed in claim 1, characterized in that the two independent connection elements (80, 90) for an adult patient (.P) respectively comprise:

four supports (4), each one provided with an electrode (3) which is connected via a cable (5) to the input (10) of the acquisition card (6);

three supports (4), each one provided with two electrodes (3) which are connected via another cable (5) to the input 11 of the acquisition card (6).

3. The device for acquiring electric signals as claimed in claim 2, characterized in that the first connection element (80) is fastened to the body of the adult patient (P) so that each support (4) is placed in such a way as to form the corners of a square substantially centered on the vertical axis XX′

displaying the position of the sternum.

4. The device for acquiring electric signals as claimed in claim 2, characterized in that the second connection element (90) is fastened to the body of the patient (P) below the heart and so that each support (4) with two electrodes (3) is oriented in a substantially curved direction running downward and to the right side of the patient.

5. The device for acquiring electric signals as claimed in claim 1, characterized in that the two independent connection elements (8, 9) for a young patient (2) respectively comprise:

two supports (4), each one provided with three electrodes (3) connected via an electric cable (5) which is connected to an input (10) of the acquisition card (6);

two other supports (4), each one provided with two electrodes (3) connected via an electric cable (5′

) which is connected to an input (11) of the acquisition card (6).

6. The device for acquiring electric signals as claimed in claim 5, characterized in that the first connection element (8) is fastened to the body of the patient (2) at the thorax so that each support (4) with three electrodes (3) is placed in a vertical direction on either side of the vertical axis XX′

displaying the position of the sternum.

7. The device for acquiring electric signals as claimed in claim 5, characterized in that the second connection element (9) is fastened to the body of the patient (2) below the heart, so that each support (4) with two electrodes (3) is oriented in a substantially curved direction running downward and to the right side of the patient (2).

8. The device for acquiring electric signals as claimed in claim 1, characterized in that each support (4) is made from a woven or nonwoven tape, provided with one self-adhesive face (12) suitable for accommodating at least one electrode (3), and which has a T-shaped profile delimited by an elongate part (13) whose ends are rounded and another rectangular part (14) having a larger surface area than the elongate part (13) and which extends the latter on its side having the greatest length.

9. The device for acquiring electric signals as claimed in claim 8, characterized in that the self-adhesive face (12) is covered with a protective film (15) made of paper or the like, having a profile similar to that of the support (4) in order to cover all the surfaces of the parts (13, 14).

10. The device for acquiring electric signals as claimed in claim 9, characterized in that the protective film (15) is cut in order to form a first detachable element (16), on the one hand, completely covering the surface of the elongate part (13) of the support (4), and on the other hand, covering half of the surface of the rectangular part (14) of said support, and a second detachable element (17) which covers the other half of the remaining surface of the part (14) of the support (4).

11. The device for acquiring electric signals as claimed in claim 1, characterized in that each electrode (3) has a surface (18) covered with gel (20) for picking up electric signals and a surface (19) for the electric connection of the cable (5, 5′

).

12. The device for acquiring electric signals as claimed in claim 8, characterized in that the electrodes (3) are positioned on the support (4) so that each surface (18) is stuck, after removing the first detachable element (16) of the protective film (15), to the self-adhesive face (12) of the elongate part (13), while each surface (19) is stuck to the self-adhesive face (12) corresponding to half the surface of the rectangular part (14).
