6. The wireless patient point-of-care network as set forth in claim 1, wherein the patient identification device stores a patient network profile containing information about each of the plurality of medical devices.

7. The wireless patient point-of-care network as set forth in claim 6, wherein the patient identification device includes:

stored software; and

a processor that selectively executes at least selected portions of the stored software to perform selected patient network services including at least;

(i) updating the patient network profile to add a medical device to the wireless patient point-of-care network, and (ii) updating the patient network profile to remove one of the medical devices from the patient point-of-care network.

8. The wireless patient point-of-care network as set forth in claim 7, wherein the updating performed by the processor includes (i) wirelessly detecting a proximate new medical device and (ii) wirelessly detecting removal of or cessation of communication with one of the medical devices of the wireless patient point-of-care network.

9. The wireless patient point-of-care network as set forth in claim 6, wherein the patient identification device includes:

stored software; and

a processor that selectively executes at least selected portions of the stored software to perform selected patient network services including at least communicating with an associated user via the wireless communication interface to selectively add a medical device to or remove a medical device from the patient network profile.

10. The wireless patient point-of-care network as set forth in claim 6, wherein the patient identification device includes:

stored software; and

a processor that selectively executes at least selected portions of the stored software to (i) receive patient information via the wireless communication interface and (ii) communicate the received patient information to an associated patient record repository via the wireless communication interface to create a new patient record on the associated patient record repository.

11. The wireless patient point-of-care network as set forth in claim 1, wherein the patient identification device further includes:

means for performing at least one medical service.
