1. A method performed by a data processor of a server that is communicatively coupled to a dialysis machine via an unsecure network, the method comprising:

  • receiving, in the data processor via the unsecure network, a request electronically for a first secure data connection from the dialysis machine, the request including a copy of a first digital certificate stored on a memory of the dialysis machine, the first digital certificate indicative that the dialysis machine is certified to connect to the data processor;

    responsive to authenticating the first digital certificate, establishing the first secure data connection over the unsecure network with the dialysis machine;

    receiving electronically, in the data processor via the unsecure network from a client device, a request to access information pertaining to an operation of the dialysis machine, the request including a copy of a second digital certificate stored on a memory of the client device, the second digital certificate indicative that the client device is certified to connect to the data processor;

    responsive to authenticating the second digital certificate, authorizing the client device to access the dialysis machine by (i) specifying an identifier of the dialysis machine, (ii) using the identifier to associate the client device with the dialysis machine on an access list, and (iii) establishing a second secure data connection over the unsecure network with the client device;

    receiving, from the dialysis machine via the first secured data connection, the information pertaining to the operation of the dialysis machine;

    determining, using the access list, that the client device is to receive the information pertaining to the operation of the dialysis machine;

    transmitting, to the client device via the second secured data connection, the received information;

    receiving, from the client device via the second secured data connection, instructions for the dialysis machine; and

    transmitting, to the dialysis machine via the first secured data connection, the received instructions to cause the dialysis machine to at least one of (i) program a prescription, (ii) change a prescription, (iii) initiate operation according to a prescription, (iv) silence an alarm or alert, (v) provide additional information, or (vi) stop an ongoing treatment.
