An electrode sensor is provided. The electrode sensor can include a conductive sensor area that is at least partially covered by hydrogel. The hydrogel can be conductive and adhere to skin. A receptacle can form an open container surrounding the conductive sensor area and the hydrogel.

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.

An patch and sensor assembly for use in an EP mapping system has two portions: a reusable portion and a disposable portion. The reusable portion houses the biosensors used in magnetic based location and mapping systems and the electrical lead necessary to communicate between the biosensor and the mapping system. The reusable portion may also contain a portion of the electrode necessary to receive electrical signals from the body of the patient. The disposable portion of the patch and sensor assembly contains an adhesive covered flexible patch having at least a portion of the electrode used to receive electrical signals form the body of the patient and may contain the electrical lead necessary to communicate such an electrical signal to the mapping system. The disposable portion contains a receptacle adapted to receive and mechanically secure the reusable portion to the disposable portion of the assembly. Such a patch and sensor assembly is useful in hybrid magnetic and impedance based location and mapping systems such as those used in electrophysiology.

Disclosed is an ECG electrode lead wire connector which provides improved electrical and mechanical coupling of the ECG electrode press stud to the lead wire and is suitable for use during imaging procedures such as, without limitation, CT scans or MRI. The connector assembly includes a housing having. An engagement member is pivotably disposed within the housing to retain the connector on an ECG electrode fixed to a patient's body, an arcuate stiffener is deposed between the engagement member and a pivot member and a radiolucent resilient member configured to bias the engagement member.

An electric conductive sensing device is provided. A front sheet of a sensing pad has several openings. A sensing electrode is a conductive ink electrode aligned with and exposed through each opening. Several first terminals are formed on an insert portion of the sensing pad and are connected to sensing electrodes. Each opening covered by a conductive gel is electrically connected to the corresponding sensing electrode. The insert portion is integrated in a connector. The present invention can be used as electrode patches of ECG devices or electric stimulators. In use, the connector is plugged into the devices to transmit tiny electrical currents to the ECG device from human skin surface, or to transmit electrical currents generated from the stimulator to human. The sensing electrodes are formed by conductive ink printing thereby simplifying the manufacturing process and lowering the manufacturing cost compared to conventional soldered structures.

The present invention relates generally to an electronic device having a housing and at least one male connection portion for detachably connection the electronic device to a female snap. The male connection portion comprises a stud having a male head portion capable of fitting within a socket region of a snap. The male head portion has a terminal end which is the terminal end of the stud and a second end which separates the male head portion from a mid-portion, and an end portion opposite the male head portion. The end portion has a terminal end which is second terminal end of the stud. A mid-portion is between the male head portion and the end portion. The stud is in electrical contact with an electronic component of the electronic device, and the head portion has a centered cavity open at the terminal end of the male head portion.

The present invention is directed to a physiological recording device, or other types of sensors to detect a biopotential, and more particularly, a physiological recording electrode that can be used without skin preparation or the use of electrolytic gels. The invention is further directed to the configurations of structures on the physiological recording electrode's lower surface. The structures having a length, width, and height, which are capable, at least in part, of transmitting an electric potential from the skin which can be measured. The structures may or may not limit the depth of application, and/or anchor the electrode or other device during normal application, and/or allow for uniform application of the electrode or other device over unprepared skin.

A physiological signal detecting device includes a carrier, an electrode layer fixed on the carrier for receiving a physiological signal, and a signal transmitter buckled on the electrode layer and the carrier. The signal transmitter includes a transmitting member and an external connector. The transmitting member includes a first sheet, a column extending from the first sheet, and a thorn curvedly extending from the first sheet. The external connector includes a ring-shaped second sheet and a hollow protrusion extending from an inner edge of the second sheet. The thorn has a sharp end piercing into the electrode layer, the column passes through the electrode layer and the carrier, and a free end portion of the column exposes from the carrier. The protrusion is sleeved at and fastened to the free end portion so that the carrier and the electrode layer are sandwiched between the first and second sheets.

A wearable electrode includes: a garment including an outer member and a backing member configured to cover at least a part of an inner surface of the outer member; and an electrode unit configured to come into contact with a living body clothed in the garment to acquire a biological signal emitted by the living body and attached to an opposite side of the backing member from the outer member, and a core wire which can be inserted into an accommodation section formed in the electrode unit. The outer member and the backing member are connected to a part other than a part of the backing member, to which the electrode unit is attached.
