One aspect is a system for reception or emission of an electrical signal from or into the human or animal body, comprising at least one insulated electrical conductor; a sleeve-shaped electrode that is electrically connected to the electrical conductor and includes an internal side, an external side, and a channel, wherein the channel defines a longitudinal axis along which the conductor is arranged. According to one embodiment, the conductor extends without interruption along the entire area of the electrode, and the electrode further includes a slit that extends from the internal side to the external side of the electrode and in which the conductor is appropriately arranged in the slit such that the electrode forms a direct durable mechanical and electrical connection to the conductor.

A clip assembly for attaching an electrical lead to a medical electrode. The clip assembly has opposing jaws that can be selectively clipped onto a medical electrode. The jaws are opened and closed using handles. A receptacle is disposed in one handle for receiving the electrical lead. Within the receptacle, the electrical lead makes contact with a shaped conductor. The shaped conductor extends into a jaw and contacts the medical electrode. A clamp is integrated into the handle. The clamp is used to selectively press the electrical lead against the shaped conductor in the receptacle. The clamp can be manually tightened and loosened. As such, the electrical lead can be readily attached to, and disconnected from, the clip assembly as needed.

A patient monitoring system has a patient monitor and a patient sensor connected to the patient monitor by a measurement cable.
