Abstract

A system and method for transmitting implant data includes an orthopedic implant, a wireless receiver, and a processing circuit electrically coupled to the wireless receiver. The orthopedic implant is configured to transmit implant identification data and implant sensor data to the wireless receiver in response to a power signal. The orthopedic implant may transfer the data over, for example, a wireless network. The processing circuit receives the implant identification data and the implant sensor data from the wireless receiver and is configured to retrieve patient-related data from a database based on the implant identification data. The processing circuit may also be configured to update a patient queue, assign a patient room to a patient, and/or transmit the patient-related data and the implant sensor data to a client machine located in the patient room.

Claims

1. A method comprising:

detecting, by a controller, a patient in a passageway defined between a number of walls of a gate of a healthcare facility;

energizing a primary coil positioned in the gate to generate a power signal in response to the controller detecting the patient in the passageway;

receiving the power signal generated by the primary coil with a secondary coil of an orthopaedic implant implanted in the patient'"'"'s body;

receiving, with circuitry in the orthopaedic implant, an output signal from a sensor in the orthopaedic implant in response to receiving the power signal;

wirelessly transmitting implant identification data and the output signal from the circuitry in the orthopaedic implant in response to the receiving output signal from the sensor and the power signal;

validating, by the controller, security code data associated with the patient;

retrieving, by the controller, patient-related data from a database based on the implant identification data and in response to validating the security code; and

updating, by the controller, an electronically-stored patient queue for the healthcare facility in response to receiving the implant identification data and retrieving the patient-related data.

2. The method of claim 1, wherein receiving the power signal comprises transcutaneously receiving an amount of energy from the primary coil with the secondary coil.

3. The method of claim 1, wherein receiving, with circuitry in the orthopaedic implant, the output signal from a sensor comprises receiving an output signal from a sensor selected from the group consisting of a pressure sensor, a load sensor, a temperature sensor, and a hall-effect sensor.

4. The method of claim 1, wherein wirelessly transmitting the implant identification data and the output signal comprises wirelessly transmitting the implant identification data and the output signal at a frequency of about 2.4 gigahertz.

5. The method of claim 1, wherein wirelessly transmitting the implant identification data and the output signal comprises wirelessly transmitting the implant identification data and the output signal using a wireless local area network frequency.

6. The method of claim 1, wherein wirelessly transmitting the implant identification data and the output signal comprises wirelessly transmitting the implant identification data and the output signal using a Bluetooth transmission protocol.

7. The method of claim 1, wherein wirelessly transmitting the implant identification data and the output signal comprises wirelessly transmitting the implant identification data and the output signal to a wireless router.

8. The method of claim 1, further comprising powering a processing circuit of the orthopaedic implant with the power signal.
