Abstract
A magnetic connector has a receptacle and a plug. The receptacle has an electromagnet comprising an inner core, an outer core, a coil disposed around the inner core and an air gap defined by the edges of the inner and outer cores. The plug has a plug core and an anchor defined by the plug core edge. The anchor is configured to insert into the air gap as a receptacle socket electrically connects with plug pins. The coil is energized and de-energized so as to assist in the insertion or removal of the anchor from within the air gap and the corresponding connection and disconnection of the socket and pins.
Claims10
A magnetic connector for a patient monitoring system where a patient monitor communicates with and receives information from a sensing device and the communications are sensitive to magnetic interferences, the connector comprising:
- a receptacle having a first contact set proximate a first magnetic connector, the first magnetic connector comprising an inner receptacle core, an outer receptacle core, and a coil wound around the inner receptacle core and enclosed by the outer receptacle core, wherein a magnetic field is generated upon application of a current to the coil, a magnetic flux resulting from the magnetic field being substantially confined within walls of the inner and outer receptacle cores;
- and
- a plug having a second contact set proximate a second magnetic connector,
- wherein the first magnetic connector is configured to magnetically attract the second magnetic connector when the plug is oriented in a first alignment with the receptacle, the first alignment permitting an electrical connection between the first contact set and the second contact set, wherein the electrical connection between the first contact set and the second contact set communicatively couples a patient monitoring device with a sensing device.
A receptacle of a magnetic connector for a patient monitoring system where a patient monitor communicates with and receives information from a sensing device and the communications are sensitive to magnetic interferences, the receptacle comprising:
- a first contact set proximate a magnetic connector, the magnetic connector comprising an inner receptacle core, an outer receptacle core, and a coil wound around the inner receptacle core and enclosed by the outer receptacle core, wherein a magnetic field is generated upon application of a current to the coil, a magnetic flux resulting from the magnetic field being substantially confined within walls of the inner and outer receptacle cores,
- wherein when a plug is connected in a first alignment with the receptacle, the magnetic connector of the receptacle is configured to magnetically attract a magnetic connector of a plug, the first alignment permitting a connection between the contact set of the receptacle and a contact set of the plug such that a patient monitoring device is communicatively coupled with a sensing device.
