Abstract

The invention relates to a medical communication system, comprising at least one medical device (2a, 2b, 2c); a gateway (31) configured for establishing at least one wireless link to an access point; wherein the medical device (2a, 2b, 2c) comprises a unit (22a, 22b, 22c) for establishing a communication connection to the gateway (31) and a unit (21a, 21b, 21c) for establishing a direct wireless link to the access point, and wherein the medical device (2a, 2b, 2c) is configured to detect whether or not a communication connection to the gateway (3) is established and to set up a direct wireless communication link to the access point if a communication connection to the gateway (31) is not established, wherein the medical communication system is configured to set up a communication link between the medical device (2a, 2b, 2c) and the access point via the gateway (31) if a communication connection between the medical device (2a, 2b, 2c) and the gateway (31) is established.

Claims

1. A medical communication system, comprising:

a plurality of medical devices;

a gateway configured for establishing at least one wireless link to an access point;

wherein each one of the medical devices comprises a unit for establishing a communication connection to the gateway and a unit for establishing a direct wireless link to the access point; and

a communication line connected to the gateway, wherein the unit for establishing a communication connection to the gateway is configured to establish a communication connection to the gateway via the communication line and the communication line is a communication bus,

and wherein the medical devices are configured to detect whether or not a communication connection to the gateway via the communication line is established and to set up a direct wireless communication link to the access point if a communication connection to the gateway via the communication line is not established, wherein the medical communication system is configured to set up a communication link between the medical devices and the access point via the communication line and the gateway if a communication connection between the medical devices and the gateway is established via the communication line.

2. The medical communication system as claimed in claim 1, wherein the communication line is a backbone line.

3. The medical communication system as claimed in claim 2, further comprising a backbone line arrangement comprising the gateway and the backbone line.

4. The medical communication system as claimed in claim 3, wherein the backbone line arrangement is configured for supplying electrical power to the medical device.

5. The medical communication system as claimed in claim 1, wherein the plurality of medical devices is connected to the communication line and a communication link between the medical devices and the access point is established via the communication line and the gateway.

6. The medical communication system as claimed in claim 1, wherein the unit for establishing a communication connection to the gateway is configured to establish a wired electrical or optical communication connection to the gateway.

7. The medical communication system as claimed in claim 1, wherein the unit for establishing a communication connection to the gateway is configured to establish a wireless communication connection to the gateway.

8. The medical communication system as claimed in claim 1, wherein the communication line comprises a plurality of communication ports, wherein to each one of the communication ports a plurality of medical devices is assigned.

9. The medical communication system as claimed in claim 1, further comprising a device for mounting one or more medical devices and connecting them to the communication line.

10. The medical communication system as claimed in claim 1, wherein the gateway comprises at least one Wi-Fi module for establishing the at least one wireless link to the access point.

11. The medical communication system as claimed in claim 1, wherein the gateway is a non-Wi-Fi to Wi-Fi gateway.

12. The medical communication system as claimed in claim 1, wherein the medical device is a medical pump.

13. Communication method, in particular using a medical communication system according to claim 1, comprising the steps of:

providing the gateway configured for establishing at least one wireless link to an access point;

providing the plurality of medical devices, wherein each one of the medical devices comprises the unit for establishing a communication connection to the gateway and the unit for establishing a direct wireless link to the access point, and the communication line connected to the gateway, wherein the units for establishing the communication connection to the gateway are configured to establish the communication connection to the gateway via that communication line and wherein the communication line is the communication bus; and

detecting whether or not a communication connection to the gateway is established via the communication line; and

setting up a direct wireless communication link between the medical devices and the access point if a communication connection between the medical devices and the gateway via the communication line is not established or setting up a communication link between the medical devices and the access point via the communication line and the gateway if a communication connection between the medical devices and the gateway is established via the communication line.
