### Description of Device:
The DeVilbiss Sleep Recorder consists of a main control box, a chest mounted interface box and several sensors mounted to the patient. The main control box contains a Novametrix oximeter board, the microcontroller and memory board, four AA battery compartment and connectors for external devices. The main control box is intended to be placed on a night stand or near the patient's bed. A chest mounted interface box containing body position sensors and connections for a nasal thermistor, a nasal cannula, snore microphone and three ECG leads is attached to the patient. The sensors used for a standard diagnostic recording are:
- 1. ECG leads (3)
- 2. Snore Microphone
- 3. Nasal Thermistor or Nasal Cannula
- 4. Oximeter Probe
- 5. Body Position sensor (inside chest box)
A patient is fitted with the ECG leads for proper placement by a healthcare professional. The snoring channel is adjusted for optimum sensitivity while monitoring the patient then takes the DeVilbiss Sleep Recorder home and connects the chest box and oximeter probe to the main control box before going to bed. The recording duration is 8 hours max, unless the batteries are low. The DeVilbiss Sleep Recorder will stop recording early if necessary to conserve enough battery energy to download the recorded data.

Page 2 of 2
After the DeVilbiss Sleep Recorder data is downloaded to a PC, analysis is performed on one or more channels to determine SpO2 desaturations, heart rate shifts and Pulse Transit Time (PTT) shifts. The information in the study is hand scored for respiratory events and used by a healthcare professional to determine if CPAP treatment is a preferred approach.
### Statement of Intended Use:
The DeVilbiss Sleep Recorder is a portable recording system for recording of adult sleep parameters. The basic model records oxygen saturation, airflow, chest impedance, patient body position and snoring. Pulse Transit Time (PTT) and heart rate are available as optional channels. The intended environment for use of the device is in the patient's home or within an institutional setting on the order of a physician. This device is intended to aid the physician in diagnosing adult sleep apnea. A qualified medical professional should score the device's recorded signals to determine respiratory events. The DeVilbiss Sleep Recorder or any of its components should not be used as a life support device, life support system, or as a critical component of a life support device or life support system.
### General Theory of Operation:
The DeVilbiss Sleep Recorder consists of a battery powered data collection unit with sensors that monitor physiological signals. The data collection unit is connected to the sensors via a small case (chest box) that is held on the patient's chest by an elastic belt. The chest box contains a 5 position sensor for body position information, three high impedance ECG electrode inputs, an input for a snore sensor, an input for a nasal thermistor and a fitting for attaching a nasal cannula. The sensors are fitted to a patient by a medical professional and the signals are verified. Two ECG electrodes are placed on opposite sides of the chest, just below the sternum. A reference electrode is placed on the lower abdomen. The ECG leads are color coded for correct connection to the chest box. The snore sensor is attached by an adhesive ring to the side of the neck. The nasal thermistor is positioned on the upper lip, with one element located at each nostril and one extending toward the mouth. A nasal air flow signal can be obtained using a nasal cannula instead of the thermistor. A switch on the chest box selects between thermistor or cannula for the airflow signal.
#### Conclusion:
The performance tests and clinical trials completed on the DeVilbiss Sleep Recorder demonstrate substantial equivalence to the predicate devices based on types of sensors, battery operation, real time monitoring, presentation and analysis of the recorded data and intended use. The safety and effectiveness is demonstrated by the tests confirming accuracy of the recorded data to the product specifications and the conformance to electrical standards applied for a Class II Type CF device.

Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
