MedicalDeviceInput nodes in message flows

Use a MedicalDeviceInput node in a message flow to collect data from medical devices.

Each MedicalDeviceInput node uses configuration information, which is stored in a configurable service.

The configurable service defines device connections and measurement sets. A device connection contains the connection parameters of a medical device. A measurement set specifies the medical measurements that are collected from a medical device. To connect a medical device to a MedicalDeviceInput node, you must assign a device connection and a measurement set to that device. For more information about configurable services, see Configurable services in the IBM® Integration Bus product documentation.

When you use MedicalDeviceInput nodes, be aware of the following information:

Use each configurable service for a MedicalDeviceInput node in only one node.
Do not use a medical device in more than one configurable service.
Ensure that every device you use has a unique device ID.

Device connections

A device connection defines a connection to a medical device. The MedicalDeviceInput node can connect to devices that use serial port or LAN connections. A device connection specifies the following information:

The device type that is connected
The device ID of the device
The connection parameters for the device, for serial port or LAN connections
The measurement set used by the device
Location, patient ID, notes, and tag information to help identify the device connection. For an example of how to use the patient ID field, see Healthcare: Medical Devices to EMR.

Measurements and measurement sets

A measurement set defines the medical measurements that are collected by a device. Measurements within a measurement set can be discrete values, alarm alerts, or waveforms. Discrete values and alarm alerts require a polling interval to be defined in the measurement set, which specifies how often that measurement is collected. Waveform measurements generate a series of discrete values at a built-in polling interval. The measurement set used by a device is specified in the device connection for that device. A measurement set contains the following information:

The device type that uses the measurement set.
Notes and tags information about the measurement set.
A list of measurements, taken from the list of possible measurements available to the selected device type. Each measurement contains the following information:
- A primary ID and sub ID. These IDs are used to identify the data that is sent from the MedicalDeviceInput node.
- Descriptions that provide more information about the measurement and the parameter that is being measured.
- If the measurement is a discrete value or an alarm alert, it has a polling interval, measured in seconds, which defines how frequently the measurement is collected from the medical device.
- Notes and tag information about the measurement.

Medical device data in message flows

The configuration of the MedicalDeviceInput node determines the devices that are connected and the data that is collected from those devices. When the message flow containing the MedicalDeviceInput node is deployed, the data from the connected devices is sent from an output terminal of the node. The data can then be processed by your message flow using any of the nodes available in your edition of IBM Integration Bus. The measurement data is passed into the message flow as a logical message tree that you can filter, transform, aggregate, and route using standard IBM Integration Bus capabilities before writing the data to an endpoint. Example endpoints include databases, IBM WebSphere®Â MQ queues, or service calls.

For reference information about the MedicalDeviceInput node, including information about the logical message tree and node terminals, see MedicalDeviceInput node. For more information about developing message flow applications, see Developing message flow applications in the IBM Integration Bus product documentation.

Medical device status messages

Medical devices generate status messages, for example, when a device is started. Status messages that are generated by medical devices can be viewed by the following methods:

By viewing the messages generated at the Status terminal of the MedicalDeviceInput node. For more information about the format of the message generated by the Status terminal, see MedicalDeviceInput node.
By viewing messages in the IBM Integration Explorer, in the Healthcare Operational Monitoring view. For more information about monitoring medical devices by using the Healthcare Operational Monitoring view, see Monitoring medical devices.
By viewing messages in the local error logs. To view messages in the local error logs, see Local error logs in the IBM Integration Bus product documentation.
By viewing messages in a trace. To view messages in a trace, see Trace in the IBM Integration Bus product documentation.
