Abstract

The invention relates to an ECG device (1) designed as a portable hand-held device, comprising a housing (2), on the outer face of which a plurality of ECG sensors in the form of capacitive electrodes is arranged in a sensor region (3), characterized by the following features: a) the ECG device (1) has at least one flexible retaining mat (4) in the sensor region (3), which retaining mat is designed to retain at least some or all ECG sensors (20), b) the retaining mat (4) is made of liquid-tight material, c) at least some or all ECG sensors (20) are fastened to the outer face of the retaining mat (4) facing away from the housing (2).

Claims

1. An ECG device (1) embodied as a portable handheld device, comprising a housing (2), on the outer side of which a plurality of ECG sensors in the form of capacitive electrodes are arranged in a sensor region (3), characterized by the following features:

a) in the sensor region (3), the ECG device (1) includes at least one flexible holding pad (4), configured for holding at least some or all ECG sensors (20),

b) the holding pad (4) consists of liquid-tight material,

c) at least some or all ECG sensors (20) are fastened to the outer side of the holding pad (4) facing away from the housing (2).

2. The ECG device as claimed in claim 1, characterized by the following features:

a) the holding pad (4) includes at least one passage opening (42) for electric lines (22, 23),

b) at least one electric line (22, 23) is guided from at least one of the ECG sensors (20) fastened to the holding pad (4) into the housing (2) of the ECG device (1) through the passage opening (42).

3. The ECG device as claimed in claim 2, characterized in that the passage opening (42) is sealed in a liquid-tight manner by at least one of the ECG sensors (20) fastened to the holding pad (4).

4. The ECG device as claimed in claim 2, characterized in that the holding pad (4) includes a respective passage opening (42) for each ECG sensor (20) fastened to the holding pad (4), at least one electric line (22, 23) is guided from each ECG sensor (20) fastened to the holding pad (4) into the housing (2) of the ECG device (1) through the respective passage opening (42) and the passage opening (42) of the respective ECG sensor (20) is sealed in a liquid-tight manner.

5. The ECG device as claimed in claim 1, characterized in that the housing (2) of the ECG device (1) includes a handle region (5) and/or handle elements, wherein the handle region (5) and/or the handle elements are configured to allow an operating person to hold the ECG device (1), wherein the holding pad (4) is arranged outside of the handle region (5) and the region of the handle elements.

6. The ECG device as claimed in claim 1, characterized in that one, several or all of the ECG sensors (20) include an electrically insulated sensor surface (21) facing away from the holding pad.

7. The ECG device as claimed in claim 6, characterized in that the electrical insulation of the sensor surface (21) is embodied as a biocompatible lacquer coating of the sensor surface.

8. The ECG device as claimed in claim 1, characterized in that the holding pad (4) is fastened on a layer (30) of elastic damping material to the housing (2), which layer is arranged between the holding pad (4) and a wall (51) of the housing (2) of the ECG device (1).

9. The ECG device as claimed in claim 1, characterized in that one, several or all of the ECG sensors (20) fastened to the holding pad (4) are individually sprung in relation to the housing (2) of the ECG device (1) by means of at least one respective spring element (50).

10. The ECG device as claimed in claim 1, characterized in that the holding pad (4) includes respective fastening points (40) for one, several or all of the ECG sensors (20) fastened to the holding pad (4), at which fastening points the ECG sensors (20) are fastened to the holding pad (4), wherein one, several or all of the fastening points (40) are respectively surrounded by a material region (43) of the holding pad (4) which has a greater flexibility than the material regions of the holding pad (4) respectively adjoining this material region (43).

11. The ECG device as claimed in claim 1, characterized in that the holding pad (4) includes respective fastening points (40) for one, several or all of the ECG sensors (20) fastened to the holding pad (4), at which fastening points the ECG sensors (20) are fastened to the holding pad (4), wherein one, several or all of the fastening points (40) are embodied as receptacle frames (41), in which in each case a respective one ECG sensor (20) is inserted.
