ROTATING ELECTRICAL CONNECTOR ADN RESPIRATORY GAS DELIVERY SYSTEM EMPLOYING SAME

摘要

A connection assembly for rotateably and electrically coupling an accessory to a main device includes a housing portion, a rotatable port assembly, and a wire assembly. An end of the port assembly is coupled to the accessory. The port assembly includes an electrical connector member having a first connector end electrically coupled to the accessory. The wire assembly has an electrical wire member having a first end electrically coupled to a second connector end of the electrical connector member and a second end electrically coupled to a power supply. The wire member is spooled around the port assembly and encased in a chamber defined between the housing portion and the port assembly. Rotation of the port assembly in opposite directions causes the electrical wire member to spool more and less tightly around the port assembly without causing pinching or tangling of wires.
