An example method includes receiving, in an intermediate data transfer unit, data related to a patient from at least one of a weight sensor, a blood pressure sensor, or a remote exchange device. The method also includes causing the intermediate data transfer unit to detect a connection of a memory device to a port of the intermediate data transfer unit, and causing the intermediate data transfer unit to store the data to the memory device so that the memory device can be transported to a dialysis machine for transfer of the data from the memory device to the dialysis machine. ## Claims ### Claim 1 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, a blood pressure sensor, or a remote exchange device; 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 connected memory device for transporting the data to a dialysis machine via the memory device; erasing, via the data transfer unit, the data for the patient after an input device is pressed; and enabling accepting of new data after the data stored in the data transfer unit is erased. ### Claim 2 (depends on 1) The method of claim 1, wherein the memory device is a first memory device, the patient is a first patient, and the dialysis machine is a first dialysis machine, the method further comprising: receiving, in the data transfer unit, data related to a second patient from the at least one of the weight sensor, the blood pressure sensor, or the remote exchange device; detecting, via the data transfer unit, a connection of a second memory device to the port of the data transfer unit; and storing, via the data transfer unit, the data related to the second patient in the second memory device. ### Claim 3 (depends on 1) The method of claim 1, which includes receiving the data wirelessly in the data transfer unit from the at least one of the weight sensor, the blood pressure sensor, or the remote exchange device. ### Claim 4 (depends on 1) The method of claim 1, further comprising pairing the data transfer unit with the at least one of the weight sensor, the blood pressure sensor, or the remote exchange device before communicating the data related to the patient. ### Claim 5 (depends on 4) The method of claim 4, wherein pairing the data transfer unit with the at least one of the weight sensor, the blood pressure sensor, or the remote exchange device includes: receiving at the data transfer unit at least one of an address or security identification number of the at least one of the weight sensor, the blood pressure sensor, or the remote exchange device; and storing, in a memory of the data transfer unit, the at least one of the address or security identification number of the at least one of the weight sensor, the blood pressure sensor, or the remote exchange device. ### Claim 6 (depends on 5) The method of claim 5, wherein pairing the data transfer unit with the at least one of the weight sensor, the blood pressure sensor, or the remote exchange device includes causing the at least one of the weight sensor, the blood pressure sensor, or the remote exchange device to store to a local memory, of the respective weight sensor, the blood pressure sensor, or the remote exchange device, at least one of an address or a security identification number of the data transfer unit. ### Claim 7 (depends on 4) The method of claim 4, further comprising placing the data transfer unit into a wireless discoverable mode for pairing with the at least one of the weight sensor, the blood pressure sensor, or the remote exchange device. ### Claim 8 (depends on 1) The method of claim 1, further comprising receiving additional data in the data transfer unit from at least one of (i) a temperature sensor, (ii) a bioimpedance sensor, or (iii) a glucose monitor. ### Claim 9 (depends on 1) The method claim 1, wherein the memory device is associated with a username and password, the method further comprising: prompting, via the data transfer unit, a user for the username and password;
