AI for Building Medical Device UIs from Surgical Procedure Recordings

TL;DR: Replay leverages AI, specifically Gemini, to analyze surgical procedure videos and automatically generate functional UI code for medical devices, drastically reducing development time and improving accuracy.

Building the Future of Medical Device UIs with AI#

The medical device industry demands precision, reliability, and speed. Developing user interfaces (UIs) for these devices is traditionally a slow, painstaking process, often requiring extensive manual coding and iterative testing. Imagine the possibilities if we could automate UI creation directly from real-world usage data – surgical procedure recordings. This is where AI, and specifically Replay, steps in to revolutionize medical device UI development.

Traditional screenshot-to-code tools fall short because they only capture visual elements. They lack the crucial understanding of why a user interacts with the UI in a specific way. They don't understand the behavior behind the interaction. Replay, on the other hand, uses Behavior-Driven Reconstruction to analyze video recordings, understanding the user's intent and translating that into functional code.

Replay: Behavior-Driven Reconstruction for Medical Devices#

Replay utilizes advanced AI algorithms, powered by Gemini, to dissect surgical procedure recordings. It identifies key UI elements, tracks user interactions, and infers the underlying logic driving those interactions. This enables the automated generation of functional UI code, significantly accelerating the development process.

Here's a comparison of Replay against traditional and other AI-powered UI generation methods:

How Replay Works: From Video to Code#

Replay's process can be broken down into several key stages:

1. •

   Video Ingestion: The surgical procedure recording is uploaded to Replay. The video can be of varying quality and formats.

2. •

   AI-Powered Analysis: Gemini analyzes the video, identifying UI elements, tracking user interactions (taps, swipes, selections), and inferring the underlying logic. This includes understanding state changes and data flow.

3. •

   Code Generation: Based on the analysis, Replay generates clean, functional UI code. This code can be customized and integrated into existing medical device software.

4. •

   Supabase Integration (Optional): Replay can seamlessly integrate with Supabase to manage data persistence and backend functionality.

5. •

   Style Injection: Replay allows for style injection to ensure the generated UI adheres to the specific design guidelines of the medical device.

Example: Generating a UI for an Infusion Pump#

Let's consider a scenario where we want to generate a UI for an infusion pump based on a video recording of a clinician setting up the device.

Step 1: Upload the Surgical Procedure Recording#

Upload the video of the clinician interacting with an existing infusion pump to Replay.

Step 2: Replay Analyzes the Video#

Replay identifies the key UI elements, such as:

• •Drug selection dropdown
• •Dosage input field
• •Flow rate input field
• •Start/Stop button
• •Alarm indicators

It also tracks the clinician's interactions with these elements, such as selecting a drug, entering the dosage, and starting the infusion.

Step 3: Code Generation#

Replay generates the following code (example in React):

typescript
// Generated by Replay
import React, { useState } from 'react';

const InfusionPumpUI = () => {
  const [drug, setDrug] = useState('Select Drug');
  const [dosage, setDosage] = useState(0);
  const [flowRate, setFlowRate] = useState(0);
  const [isRunning, setIsRunning] = useState(false);

  const handleDrugChange = (event: React.ChangeEvent<HTMLSelectElement>) => {
    setDrug(event.target.value);
  };

  const handleDosageChange = (event: React.ChangeEvent<HTMLInputElement>) => {
    setDosage(parseFloat(event.target.value));
  };

  const handleFlowRateChange = (event: React.ChangeEvent<HTMLInputElement>) => {
    setFlowRate(parseFloat(event.target.value));
  };

  const handleStartStop = () => {
    setIsRunning(!isRunning);
    // Add logic to start/stop the infusion pump here
  };

  return (
    <div>
      <h1>Infusion Pump Control</h1>
      <label>Drug:</label>
      <select value={drug} onChange={handleDrugChange}>
        <option>Select Drug</option>
        <option>Insulin</option>
        <option>Antibiotic</option>
        <option>Pain Medication</option>
      </select>
      <br />
      <label>Dosage (mg):</label>
      <input type="number" value={dosage} onChange={handleDosageChange} />
      <br />
      <label>Flow Rate (mL/hr):</label>
      <input type="number" value={flowRate} onChange={handleFlowRateChange} />
      <br />
      <button onClick={handleStartStop}>{isRunning ? 'Stop' : 'Start'}</button>
      <br />
      {isRunning && <p>Infusion running...</p>}
    </div>
  );
};

export default InfusionPumpUI;

This code provides a basic functional UI for the infusion pump. You can further customize it by adding styling, validation, and integration with the actual infusion pump hardware.

Step 4: Style Injection#

You can inject custom CSS styles to match the design of your medical device. Replay provides a mechanism to easily apply these styles to the generated code. For example:

css
/* Custom styles for the infusion pump UI */
body {
  font-family: sans-serif;
}

h1 {
  color: #007bff;
}

label {
  font-weight: bold;
}

input[type="number"] {
  padding: 5px;
  border: 1px solid #ccc;
  border-radius: 4px;
}

button {
  background-color: #28a745;
  color: white;
  padding: 10px 20px;
  border: none;
  border-radius: 4px;
  cursor: pointer;
}

💡 Pro Tip: Use a component library like Material UI or Ant Design to quickly style your UI and ensure consistency.
