Abstract
A physiological sensor assembly is provided that includes at least one electrode having a sensing surface and a body. The body has a plurality of exterior surfaces, including a contact surface, at least one pocket disposed in the contact surface, at least one gel vent in fluid communication with the at least one pocket, and at least one vent passage configured to provide fluid communication between the at least one gel vent and at least one exterior surface. The at least one pocket is open to the contact surface. The at least one electrode is disposed in the at least one pocket.
Claims18
A physiological sensor assembly, comprising:
- at least one electrode having a sensing surface;
- and
- a body having a plurality of exterior surfaces including a contact surface, and at least one pocket disposed in the contact surface, wherein the at least one pocket is open to the contact surface and the at least one electrode is disposed in the at least one pocket, and at least one gel vent in fluid communication with the at least one pocket, and at least one vent passage configured to provide fluid communication between the at least one gel vent and at least one said exterior surface.
A system for sensing a physiological parameter, comprising:
- at least one sensor assembly having:
- at least one electrode having a sensing surface, the electrode configured to produce first electrical signals representative of second electrical signals sensed from a patient;
- and
- a body having a plurality of exterior surfaces including a contact surface, and at least one pocket disposed in the contact surface, wherein the at least one pocket is open to the contact surface and the at least one electrode is disposed in the at least one pocket, and at least one gel vent in fluid communication with the at least one pocket, and at least one vent passage configured to provide fluid communication between the at least one gel vent and at least one said exterior surface;
- and
- a base unit having a system controller in communication with the at least one electrode of the sensor assembly and a non-transitory memory storing instructions, which instructions when executed cause the system controller to process the first electrical signals to produce information relating to the physiological parameter.
