## Device Description
The F&P Eson™ 2 Nasal Mask is a non-invasive patient interface with a silicone seal which covers around the nose of a patient held in place by adjustable headgear straps.
The mask connects to a single breathing tube via a 22mm swivel adaptor to receive pressurized gases from a continuous airway pressure device (CPAP or Bi-level). The exhaust holes on the elbow of the mask allow exhaled gases to be flushed out while the system is in operation.
The F&P Eson™ 2 Nasal Mask is a prescription only device, provided in a non-sterile state.
An oxygen pressure port accessory is available to be used with the device for oxygen therapy and/or gas monitoring (previously covered by K121597 F&P Eson Nasal Mask).
### Indications for Use
The F&P Eson™ 2 Nasal Mask is intended to be used by individuals who have been diagnosed by a physician as requiring CPAP or Bi-level therapy. The F&P Eson™ 2 Nasal Mask is intended for single patient adult (≥ 66lb (30kg)) use in the home and for multiple patient adult use in the hospital or other clinical setting where proper disinfection of the device can occur between patient uses.
### Technological Characteristics Comparison
The F&P Eson™ 2 Nasal Mask has the following similarities to the previously cleared predicate Eson™ Nasal Mask (K121597):
- -Substantially equivalent intended use with same patient population and operating environment.
- -Same mode of operation whereby both masks deliver gases through the nose.
- -Same breathing tube connection mechanism via a 22mm connector.
- -Same RollFit™ seal mechanism where the silicone seal rolls back and forward on the bridge of the nose.
- -Both new and the predicate device headgear are designed to attach at the same four points on the mask frame.
The key differences to the predicate device are that the F&P Eson™ 2 Nasal Mask:
- Has colour cues (VisiBlue™) added to swivel, frame, seal, and headgear components to aid in reassembly and orientation of the mask.
- Provide a simpler diffuser system whereby the diffuser mat and the cover have been integrated into a single component and is washable.
- -Has a detachable elbow to aid in mask cleaning and disinfection.
- -Has a headgear which allows over the head fitting of the mask.
- -Has a notch mechanism for crown strap headgear adjustment, removing the need of a headgear buckle piece for adjustment.

## Non-Clinical Tests
Testing of the F&P Eson™ 2 Nasal Mask was compared to the predicate K121597 Eson Nasal Mask for performance and biocompatibility. These tests demonstrate substantial equivalence of the F&P Eson™ 2 Nasal Mask to the predicate device.
The F&P Eson™ 2 Nasal Mask has been tested to the following standards:
- . ISO 17510-2:2007 Sleep Apnoea Breathing Therapy - Part 2: Masks and Applications Accessories
- . ISO 10993-1:2009 Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing Within a Risk Management Process
Specific tests used to show conformance to these standards include:
- . Transportation and storage testing to provide evidence that the mask will perform as intended once it arrives to the prescribed user. Results were that the product had no
{11}------------------------------------------------
visible deformations, sufficiently removed CO2 through the exhaust vents, had no visible lint on the seal, had no offensive odour, that the packaging was still intact.
- . Automatic High-Level Disinfection to provide evidence that the mask can effectively be disinfected in a certified washer disinfector. The mask was able to achieve the minimum 6 log reduction.
- Thermal Disinfection to provide evidence that the mask can effectively be disinfected through thermal disinfection cycles of 75°C for 30min, 80°C for 10min and 90°C for 1min. The mask was able to be thermally disinfected through the predetermined cycles.
- . Sound Emissions to provide evidence that the sound pressure level is less than 25 dBA. Mask was able to achieve a sound pressure level of less than 25dBA with the diffuser system.
- . Carbon Dioxide Flushing to determine if the mask is able to meet the minimum carbon dioxide flush rate. Under the worst case scenario, the mask was able to sufficiently flush carbon dioxide at a suitable rate.
- Shelf Life Assessment to show that the materials used in the mask have the ability to . retain their structural integrity during storage. It was determined that the mask's materials have well known properties, are very stable and present a very remote risk of degradation within a shelf life of 10 years.
### Clinical Tests
Not applicable - no clinical testing was performed with respect to the Eson™ 2 nasal mask.
#### Conclusion
The comparison of features, performance, and intended use demonstrate that the F&P Eson™ 2 Nasal Mask is substantially equivalent to the predicate K121597 Eson Nasal Mask.
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.
