It seems like you're using HL7 v2.x. We're focused on HL7 FHIR. But of
course, you could use existing libraries to create the message.

Our friends from CRS4 have created the hl7apy, a library that
implements the Minimal Lower Layer Protocol (MLLP), used in HL7 v2.
They have actually created GNU Health modules to implement the server
and the PDQ. 

Please take a look at : http://hl7apy.org/

For some examples : http://hl7apy.org/tutorial/index.html#tutorial

In addition to the HTTP and FTP protocols, FHIR standard could also
use MLLP for message exchange.

I would love to go to Cordoba ! It's such a great city, but due to time
constraints of this short trip, I will be in Buenos Aires.

Anyways, just send me an email and we can have a talk during these days.
