Step 1: Collect HL7 Health Records

Python to Send JSON Data to MQTT (Data Generated by https://www.mockaroo.com/)

import paho.mqtt.client as mqtt
import json
# MQTT
client = mqtt.Client()
client.connect("localhost", 14162, 60)
row = [{"PID_SSNNumberPatient":823456789,"email":"ahospital0@census.gov","gender":"Male","ip_address":"138.135.180.206","drug_provider":"OrchidPharma Inc","icd9":"94140","icd9_description":"Deep necrosis of underlying tissues [deep third degree] without mention of loss of a body part, face and head, unspecified site","icd9P_proc":"7942","icd9_proc_description":"Closed reduction of separated epiphysis, radius and ulna","user_agent":"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_5_8) AppleWebKit/535.1 (KHTML, like Gecko) Chrome/14.0.801.0 Safari/535.1","drug_used":"Naratriptan"}]
json_string = json.dumps(row)
client.publish("patientdata",payload=json_string,qos=1,retain=False)
client.disconnect()

Step 2: Get to Apache NiFi via FTP, sFTP, File, Apache Kafka, MQTT, REST API, TCP/IP or hundreds more options.
