Abstract

The invention relates to remote controlled blood cleaning of a patient (P). A dialysis unit (110) treats the patient'"'"'s (P) blood in accordance with a prescribed therapy. The dialysis unit (110) has a bi-directional wireless interface (110W-120W) towards a gateway unit (120), which is further connected (125) to a remote host (140) via at least one interconnecting network (130). Thus, therapy related parameters (D_bp, D_r, d_h, D_w) can be transmitted from the dialysis unit (110) to the remote host (140). It is also rendered possible for the remote host (140) to transmit control data (D_ctr1) to the dialysis unit (110), the control data (D_ctr1) influencing the prescribed therapy being, or to be, executed by the dialysis unit (1 10).

Claims

1. A medical system for cleaning the blood of a patient, the system comprising:

a dialysis unit configured to treat blood in accordance with a prescribed therapy, the dialysis unit having a wireless interface for bi-directional exchange of data, and

a gateway unit configured to communicate with the dialysis unit over the wireless interface, the gateway unit having an interface configured to be connected to a remote host via at least one interconnecting network, and the gateway unit being further configured to provide a bidirectional exchange of data between the remote host and the dialysis unit, wherein the dialysis unit is configured to;

influence the prescribed therapy in response to control data received from the remote host via the gateway unit, the control data being received during an ongoing treatment, and

modify at least one parameter of the prescribed therapy in respect of the ongoing treatment before completing said ongoing treatment.

2. The system according to claim 1, wherein the control data defines at least one parameter of a prescribed therapy of a future treatment, and the dialysis unit is configured to perform the future treatment in accordance with a prescribed therapy being adjusted with respect to the at least one parameter.

3. The system according to claim 2, wherein the control data defines an entire prescribed therapy of a future treatment.

4. The system according to claim 1, wherein the dialysis unit is configured to transmit at least one effect parameter to the remote host via the gateway unit, the at least one effect parameter reflecting a result of a treatment performed by the dialysis unit.

5. The system according to claim 1, wherein the system comprises a blood pressure monitor configured to register at least one blood pressure related parameter, the blood pressure monitor having a wireless interface towards the gateway unit, and the blood pressure monitor being configured to transmit at least one of the at least one blood pressure related parameter to the remote host via the gateway unit.

6. The system according to claim 1, wherein the dialysis unit is configured to transmit at least one machine parameter to the remote host via the gateway unit, the at least one machine parameter reflecting a status or a setting of at least one characteristic of the dialysis unit.

7. The system according to claim 1, wherein the system comprises a scale unit configured to register a weight parameter, the scale unit having a wireless interface towards the gateway unit, and the scale unit being configured to transmit the weight parameter to the remote host via the gateway unit.

8. The system according to claim 1, wherein the dialysis unit comprises a memory module configured to store data representing at least one executed treatment, and the dialysis unit is configured to transmit at least a fraction of the stored data to the remote host via the gateway unit.

9. The system according to claim 1, wherein the dialysis unit comprises at least one software module configured to control at least one function of the dialysis unit, and the dialysis unit is configured to:

receive software updating data from the remote host via the gateway unit, and

modify at least one of the at least one software module in response to the software updating data.

10. The system according to claim 1, comprising a first data input unit configured to register manually entered information, the first data input unit having a wireless interface towards the gateway unit, and the data input unit being configured to transmit the manually entered information to the remote host via the gateway unit.

11. The system according to claim 1, comprising a second data input unit configured to:

automatically register machine readable information, and

forward the machine readable information to the remote host via the gateway unit.

12. A dialysis unit configured to clean blood in accordance with a prescribed therapy, the dialysis unit having a first wireless interface for bi-directional exchange of data, and the dialysis unit being configured to communicate with a remote host via a gateway unit having a second wireless interface matched to the first wireless interface, gateway unit being further connected to the remote host via at least one interconnecting network, wherein the dialysis unit is configured to influence the prescribed therapy in response to control data received from the remote host via the gateway unit, the control data being received during an ongoing treatment, and the dialysis unit is configured to modify at least one parameter of the prescribed therapy in respect of the ongoing treatment before completing said ongoing treatment.

13. A method for controlling a medical system configured to clean blood, the method comprising:

exchanging bidirectional data wirelessly between a gateway unit and a dialysis unit, the dialysis unit being configured to treat the blood in accordance with a prescribed therapy, and the gateway unit being further connected to a remote host via at least one interconnecting network, and

exchanging bidirectional data between the remote host and the gateway unit, wherein said exchanging bidirectional data includes;

receiving in the gateway unit control data transmitted from the remote host,

transmitting the control data from the gateway unit to the dialysis unit over the wireless interface,

receiving the control data in the dialysis unit during an ongoing treatment, and in response to the control data,

modifying at least one parameter of the prescribed therapy in respect of the ongoing treatment before completing said ongoing treatment.

14. The method according to claim 13, wherein the control data defines at least one parameter of a prescribed therapy of a future treatment, the method further comprising performing the future treatment in accordance with a prescribed therapy being adjusted with respect to the at least one parameter.

15. The method according to claim 14, wherein the control data defines an entire prescribed therapy of a future treatment.
