System for automated data collection of patient parameters using wired or wireless technology

An intermediate data transfer unit apparatus (90) is described. The apparatus comprises: a housing separated from a housing of a first dialysis machine (10) and a housing of a second dialysis machine (10); an inlet device (92); a port (25) carried by the housing of the intermediate data transfer unit and individually connectable to a first memory device (85) and a second memory device (85) to allow data transfer with the first dialysis machine, which is configured to communicate with the first memory device, and the second dialysis machine, which is configured to communicate with the second memory device; and an interface (15) for wirelessly receiving data from at least one of a weight sensor (80), a blood pressure sensor (80) or a remote exchange device (80). The intermediate data transfer unit is programmed to: receiving data, via the interface, from at least one of the weight sensor, the blood pressure sensor or the remote exchange device for a patient, storing the data in the first or second memory device when the first or second memory device is connected to the port such that the data is communicated to the respective first or second dialysis machine after the first or second memory device is moved from the port to the respective first or second dialysis machine, communicating the data for the patient to the first dialysis machine via the first memory device, and erase data for the patient and allow acceptance of new data after pressing the input device (92). A method of storing dialysis data is also described. (Automatic translation with Google Translate, no legal value)
