The electric apparatus receives the front flap of the disposable patch electrode structure into a volume of the front part for forming a contact between the first electric contacts and the electrodes of the front flap. At least one of the back part and the front part comprises resin holes, and the compartment contains resin received through the resin holes, the resin immobilizing the front part and the back part with respect to each other and attaching them together.

The present invention relates to a body electrode for recording electrophysiological signals from a body. In particular the invention relates to a body electrode (100; 200; 400) comprising a transducer element (105; 205) shielded by a layered shield structure (120; 220; 420) and a skin contact element (115; 115′; 115″; 215) providing a contactbetween the layered shield structure (120; 220; 420) and the skin (101; 201) of the body. The layered shield structure (120; 220; 420) comprises at least an electrically conducting layer (113; 213) and an electrostatic dissipative layer (112; 212; 412). The skin contact element (115; 115′; 115″; 215) comprises an electrically onducting layer (113; 213) and an ion conducting layer (114; 214) and is with regards to the electrical potential characteristics matched with a transducer element (105; 205).

A first electrode and a second electrode are attached to a subject. A processor module acquires physiological information of the subject based on biopotential that are detected by the first electrode and the second electrode, respectively. A housing has a battery housing member for housing a primary battery which supplies an electric power to the processor module. The processor module is attachable to and detachable from the housing.

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.

A multiparameter monitor (MPM) for a patient includes a disposable electrode patch (DEP) comprising a plurality of male snap post electrodes, an optics interface and a thermal/respiratory interface to a skin surface of the patient. The MPM also includes an electronics module and wireless transmitter (EMT) in connection with a plurality of female snap receptors and configured to transmit a signal data based on a connection and a disconnection of the plurality of the female snap receptors to the male snap post electrodes.
