Configuring Channels for PeraHealth

Depending on the configuration you set up, you will need either four or two Mirth channels.

In this integration, the PeraHealth HL7s fields are mapped similar to the CWE HL7s fields and output JSON file. Subsequently it is sent to HL7 folder of Message Generator of CWE.

Note: The channels for PeraHealth support Mirth version 2.2.1.
Table 1. PeraHealth Channels
Channel Type Description
PHHL7Receiver.xml TCP listener channel that listens on port 6661 for HL7 messages. It forwards the individual messages to the 'PHJSONCreator' channel. The destination of this channel is Channel writer.
PHJSONCreator.xml Used to transform the message into JSON and subsequently forwards the JSON to the load balancer on port 6666.
PHJSONReceiver.xml It is the LLP listener that listens on port 6666. The destination of this channel is the file writer that writes the JSON file in the HL7 directory
PHMonitor.xml TCP listener channel, that is, it acts as the monitor channel for load balancer and listens on port 5000.

Following are the three types of alarms sent from the PeraHealth system:

For a high-availability environment, Vocera recommends the following configuration:

In this configuration, two CWE servers are behind a load balancer, and Mirth Connect is installed on each of these servers. For each copy of Mirth, you must create the following channels:

On each copy of Mirth, follow the instructions in Importing an Existing Channel to import the channels, and then configure the channels as follows:

  1. In the PHHL7Receiver channel, click the Source tab. In the Listener Port field, type the port that the patient gateway is using.
  2. In the PHJSONCreator channel, click the Destinations tab. In the Host Address field, type the IP address of the load balancer. Set Keep Connection Open to Yes if you want to maintain a persistent connection to the JsonReceiver channel (Vocera does not recommend this).
  3. In the PHJSONReceiver channel, click the Destinations tab. The path specified in the Directory field is set to C:/Vocera/mVisum Alerts/MVisum Message Generator/HL7 by default. If you have installed CWE in a folder other than C:/Vocera, update the Directory field accordingly.
  4. In the PHMonitor channel, click the Destinations tab. The path specified in the Directory field is set to C:/Vocera/mVisum Alerts by default. If you have installed CWE in a folder other than C:/Vocera, update the Directory field accordingly.
Note:

After you have configured your Mirth channels, you can add additional alarm reasons or alarm levels if needed. See Configuring a New Alarm Reason and Configuring a New Alarm Level for more information.
