System for automatic continuous and reliable patient identification for association of wireless medical devices to patients
First Claim
1. A medical communications system comprising:
- a plurality of patient identification devices, each connected with and carried by one patient and including;
a patient identification device electronic patient identification code memory which stores a patient identification code for the one patient; and
an intra-body communication device including;
an intra-body communications transmitter capacitively coupled to a body of the one patient to transmit data over the one patient'"'"'s body using near-field body communications; and
a patient identification device processor which controls the intra-body communications transmitter to retrieve the patient identification code from the patient identification device electronic patient identification code memory and transmit the patient identification code on the one patient'"'"'s body; and
at least one medical device which is connected with and carried by the one patient, each medical device including;
a medical device electronic patient identification code memory;
a medical device intra-body communication receiver which receives the patient identification code transmitted using the near-field communications on the one patient'"'"'s body; and
a medical device processor which (1) initially causes the medical device electronic patient identification memory to store the patient identification code received by the medical device intra-body communications receiver and (2) subsequently automatically verifies that the patient identification code stored in the medical device patient identification code memory matches each patient identification code subsequently received from the patient identification device intra-body communications transmitter to verify that the patient identification code stored in the medical device patient identification code memory identifies the one patient.

Abstract
The medical communication system comprises a plurality of medical identification devices (12). Each identification device (12) is attached to one particular patient (14). A registration processor generates a unique patient identification data that is stored in an electronic patient identification code memory (54). Each identification device (12) includes an intra-body wireless communication device (16) which transmits the patient'"'"'s identification on the patient'"'"'s body. A medical device (22), which is linked to the patient (14) to measure a vital function, periodically automatically receives the patient'"'"'s identification code to continually ensure association to a correct patient.

8. A communication method comprising:
-
assigning a wireless patient identification device to a selected patient wherein the identification device is encoded with an electronic patient identification code that uniquely identifies the selected patient to which the identification device is assigned; attaching the wireless patient identification device to one part of the selected patient; attaching at least one wireless medical device to at least one other part of the selected patient; wherein the patient identification devices and the medical device are capacitively coupled with the selected patient and communicate over the patient using near-field intra-body communications; automatically associating the wireless patient identification device to the at least one medical device by storing the electronic patient identification code of the selected patient in a memory of the medical device; and automatically verifying the association of the medical device to the selected patient including; subsequently transmitting the electronic patient identification code from the patient identification device to the medical device using the near-field intra-body communications, receiving the subsequently transmitted electronic patient identification code at the medical device, and with a processor of the medical device, comparing the subsequently received electronic patient identification code with the stored electronic patient identification code in the medical device memory. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A medical communications system comprising:
-
at least one medical device configured to be attached to a patient, the medical device including; a sensor which measures a vital sign of the patient; a medical device patient code memory which stores a patient identification code of the patient; a medical device receiver which receives communications carrying the patient identifier code; and a medical device transmitter which wirelessly transmits a signal carrying the vital signs from the sensor and the patient identification code from the medical device patient code memory to an off-patient monitor device; a patient identification device configured to be attached to the patient, the patient identification device including; a patient identification device electronic patient identification code memory which stores the patient identification code for the patient; and a transmitter which wirelessly transmits the patient identification code from the patient identification device electronic identification code memory; and a patient identification device processor which controls the transmitter to retrieve the patient identification code from the patient identification device electronic patient identification code memory and transmit the patient identification code to the at least one medical device; and wherein the medical device further includes; a medical device processor which is connected to the medical device receiver to receive the patient identification code subsequently transmitted by the patient identification device transmitter and verify that the patient identification code stored in the medical device patient code memory matches the received patient identification code. - View Dependent Claims (17, 18, 19)
