ELLA

Medical Triage & Clinical RAG Engine

Ella is a production-grade Retrieval-Augmented Generation (RAG) system purpose-built for medical triage. She ingests 90,000+ clinical text chunks, embeds them via NVIDIA NIM, stores them in Pinecone, and retrieves context-grounded answers through a multi-stage pipeline — eliminating hallucinations in healthcare workflows.

Install

pip install ella-sdk

Quick Start

from ella_medical import Ella

client = Ella()
response = client.query("What are the symptoms of a heart attack?")

print(response.intent)         # "TRIAGE"
print(response.response)       # Grounded clinical response

---

Usage

Basic Query

from ella_medical import Ella

client = Ella()
response = client.query("What are the symptoms of a heart attack?")

print(response.intent)              # "TRIAGE"
print(response.priority)            # Priority level
print(response.thought_process)     # Router's reasoning
print(response.response)            # Ella's response
print(response.retrieved_context)   # Retrieved medical documents

Multi-Turn Conversation

from ella_medical import Ella

client = Ella()

# First message
r1 = client.query("I have chest pain")

# Follow-up
r2 = client.query(
    "What about treatment options?",
    history=f"Patient: I have chest pain\nElla: {r1.response}"
)

print(r2.response)

Context Manager

from ella_medical import Ella

with Ella() as client:
    response = client.query("What are the symptoms of diabetes?")
    print(response.response)

Response Object

@dataclass
class QueryResponse:
    intent: str            # EMERGENCY | TRIAGE | BOOKING | GENERAL_INFO | CLOSING
    priority: str          # Priority level
    thought_process: str   # Router's reasoning
    justification: str     # Clinical justification
    response: str          # Ella's response
    retrieved_context: str # Retrieved medical documents
