Abstract

A testing device (10), an infusion pump or another medical device function testing method, to an anesthesia apparatus or respirator (AB) and to a computer program product are provided for testing the function of an infusion pump (G). The testing device (10) is preferably implemented on the anesthesia apparatus or respirator (AB) and comprises a memory (MEM), a test module (T) and a controller (C). The test module (T) sends a test command (20) to the infusion pump (FG), which sends a response (30) back to the controller (C) after execution of the command. The control (C) can then compare the response (30) received with a reference response (30′) for agreement in order to send a successful function test result.

Claims

1. A testing device for testing the function of an infusion pump or another medical device within a system of devices comprising an anesthesia apparatus or respirator, wherein the devices of the system of devices exchange data with one another via a communication protocol and wherein there are different configurations of the system of devices, the testing device comprising:

at least one test module sending at least one test command from the set of test commands, stored in memory, to the infusion pump or to the another medical device for processing and/or executing the test command, via the communication protocol; and

at least one controller receiving a response to the test command that has been executed by the infusion pump or to the another medical device, comparing the response with the at least one stored reference response, assigned to the respective test command, for agreement, and sending a successful function test result indication in case of agreement.

2. A testing device in accordance with claim 1, wherein in the testing device is provided on the anesthesia apparatus or respirator.

3. A testing device in accordance with claim 1, wherein the controller is configured to activate the testing device upon receiving a test activation signal.

4. A testing device in accordance with claim 1, wherein the test command comprises a simulation command.

5. A testing device in accordance with claim 1, wherein the memory is a writeable memory that can be modified at any time by writing other test commands and/or reference responses to the memory.

6. A testing device in accordance with claim 1, further comprising a control unit comprising at least one of sensors and actuators to execute the test command and to generate a control response to the test command, and wherein:

the control unit passes on the respective generated control response to the controller; and

the controller compares the response received with the control response and with the reference response for agreement.

7. A testing device in accordance with claim 1, wherein in the testing device is provided on a patient monitor.

8. A system of medical devices, the system comprising:

a plurality of medical devices including at least one device to be tested with respect to operability of at least one other device associated with the testing;

a communication interface connecting the device associated with the testing with the device to be tested;

a communication protocol established between the device associated with the testing and the device to be tested for data exchange with one another via the communication protocol and wherein there are different configurations of the system of devices;

a testing device comprising;

a memory with a stored set of test commands and with at least one stored reference response assigned to each test command, wherein the reference response is system-specific and/or configuration-specific;

at least one test module sending at least one test command from the set of test commands, stored in memory, to the device to be tested for processing and/or executing the test command, via the communication protocol; and

at least one controller receiving a response to the test command that has been executed by the device to be tested, comparing the response with the at least one stored reference response, assigned to the respective test command, for agreement, and sending a successful function test result indication in case of agreement.

9. A system in accordance with claim 8, wherein:

the plurality of medical devices includes in an anesthesia apparatus or respirator and the testing device is connected to or provided in or on the anesthesia apparatus or respirator; and

the device to be tested is an infusion pump.

10. A system in accordance with claim 9, wherein the controller is configured to activate the testing device upon receiving a test activation signal.

11. A system in accordance with claim 8, wherein the test command comprises a simulation command.

12. A system in accordance with claim 8, wherein the memory is a writeable memory that can be modified at any time by writing other test commands and/or reference responses to the memory.

13. A system in accordance with claim 8, further comprising a control unit comprising at least one of sensors and actuators to execute the test command and to generate a control response to the test command, and wherein:

the control unit passes on the respective generated control response to the controller; and

the controller compares the response received with the control response and with the reference response for agreement.

14. A system in accordance with claim 8, wherein in the testing device is provided connected to, on or as a prat of a patient monitor.

15. A system in accordance with claim 8, wherein:

the plurality of medical devices comprise a plurality of medical device modules including an anesthesia apparatus or respirator a modifiable testing device; and

the testing device comprises a modifiable testing device.

16. A system in accordance with claim 8, wherein:

the device to be tested and the device associated with the testing exchange data packets in during normal operation; and

the device to be tested sends the at least one test response as a packetized message via the communication protocol and the testing device sends test commands as a packetized message via the communication protocol.

17. A system in accordance with claim 8, wherein:

the system operates a testing method comprising a configuration phase and a testing phase, which follows the configuration phase but may also be carried out uncoupled therefrom in time.

18. A system in accordance with claim 8, wherein the testing device comprises a computer program product, wherein the computer program product comprises a computer program, which is stored on a data storage medium or in a memory of a computer forming at least a part of the memory with a stored set of test commands or which can be downloaded via a network connection and which comprises computer-readable commands, which are intended for executing method steps when the commands are being executed on the computer.

19. A testing method for testing the function of an infusion pump or of another medical device within a system of devices comprising at least an anesthesia apparatus or respirator, wherein the devices of the system of devices exchange data with each other via a communication protocol and wherein there are different configurations of the system of devices, with the following method steps:

providing a set of test commands, which are intended to be executed on the infusion pump or on the other medical device, wherein at least one reference response is assigned to each test command and wherein the reference response is system-specific and/or configuration-specific;
