Method for pairing a dialysis machine with peripheral devices

A dialysis data storage method comprising:

• receiving, in a data transfer unit, data related to a patient from at least one of a weight sensor or a blood pressure sensor;
• detecting, via the data transfer unit, a connection of a memory device to a port of the data transfer unit;
• storing, via the data transfer unit, the data in the memory device for transporting the data to a dialysis machine via the memory device;
• and
• after the memory device is removed from the port, causing the dialysis machine to detect a connection of the memory device to a device port of the dialysis machine;
• causing the connected memory device to communicate the data to the dialysis machine via the memory device detecting that an input device of the data transfer unit has been pressed;
• and
• erasing the data for the patient in the data transfer unit after making the detection of the input device having been pressed.
