Abstract

The present invention relates to electrocardiography and to electrode arrangements used in electrocardiographic monitoring devices, and is more particularly related to a pad or patch containing said electrodes which may be used to passively and non-invasively monitor electrical activity generated by a patient'"'"'s heart from the surface of that patient'"'"'s chest, and to a connector which allows for fast and simple connection between the pad containing said electrodes and the devices and equipment typically used to monitor and view electrocardiographic information.

Claims

1. An EKG patch system, comprising:

an EKG patch having a base layer and a plurality of EKG patch electrodes protruding from the base layer, said plurality of EKG patch electrodes being capable of receiving an electrical signal generated by the myocardium of a human heart;

a connector section having a first sheet comprising a plurality of connector section electrodes to match the number and location of the electrodes in the EKG patch and a second sheet comprising a plurality of electrical leads, a perimeter of the first sheet being substantially equal to a perimeter of the base layer of said EKG patch, the connector section having a shape that corresponds to the EKG patch; and

a single connector cable electrically connected to said plurality of electrical leads at a first end through a single port in said connector section, said single connector cable being suitable to be electrically connected to an EKG monitoring device at a second end, and the single connector cable being detachable partway along its length with a male and a female connection,

wherein said base layer is configured to contact skin of a human patient and attach thereto,

wherein said plurality of EKG patch electrodes are held in a fixed configuration with respect to said electrical leads of said connector section and are also configured to contact the skin of a human patient concurrently with said base layer, and

wherein said EKG patch is constructed from nonmagnetic materials such that said EKG patch is suitable for use in conjunction with magnetic fields.

2. The EKG patch system according to claim 1, wherein the plurality of EKG patch electrodes and connector section electrodes are snap electrodes, via which the EKG patch and the connector section are attachable.

3. An EKG-patch connector system, comprising:

an EKG patch comprising a base layer and a plurality of EKG patch electrodes protruding from the base layer, said plurality of EKG patch electrodes being configured to contact skin of a human patient concurrently with said base layer;

a connector section adapted to be electrically connected to the EKG patch, the connector section having a first sheet comprising a plurality of connector section electrodes to match the number and location of the electrodes in the EKG patch and a second sheet comprising a plurality of electrical leads, a perimeter of the first sheet being substantially equal to a perimeter of the base layer of said EKG patch, the connector section having a shape corresponds to the EKG patch; and

a single connector cable electrically connected to said plurality of electrical leads at a first end through a single port in said connector section, said single connector cable also being suitable to be electrically connected to an EKG monitoring device at a second end, and the single connector cable being detachable partway along its length with a male and a female connection,

wherein said plurality of EKG patch electrodes are held in a fixed configuration with respect to said electrical leads of said connector section.

4. An EKG-patch connector system according to claim 3, wherein said EKG patch connector system is constructed from nonmagnetic materials such that said EKG patch connector system is suitable for use in conjunction with magnetic resonance imaging systems.

5. The EKG-patch connector system according to claim 3, wherein the plurality of EKG patch electrodes and connector section electrodes are snap electrodes, via which the EKG patch and the connector section are attachable.
