### NAME OF LEGALLY MARKETED DEVICE FOR WHICH A CLAIM OF SUBSTANTIAL EQUIVALENCE IS MADE as required by 807.92(a)(3)
The S/5TM Device Interfacing Solution is substantially equivalent in safety and effectiveness to the legally marketed (predicate) AS/3 Interface Board, B-INT (K935477).
#### DEVICE DESCRIPTION as required by 807.92(a)(4)
The Device Interfacing Solution (DIS) has the following key components: Device specific converter module, device specific cable, bus cable to another DIS converter module, if needed, and Datex-Ohmeda monitor bus cable.
External devices are connected to the monitoring system by using converter modules that handle the communication between the device and S/5 monitoring system. These DIS converter modules convert the data coming from the connected device to a format that can be utilized in the S/5 Anesthesia Monitor, S/5 Critical Care Monitor, S/5 Compact Anesthesia Monitor, or S/5 Compact Critical Care Monitor.
The DIS converter module is connected to to the socket at the rear of the Datex-Ohmeda monitor with a bus cable. The bus cable is also used for connecting DIS converter modules to each other. Specific modules can be connected to the different type of external devices. Up to ten DIS converter modules can be connected in series. Each external device has its own specific DIS converter module that can be used only with that device. One DIS converter module is needed for interfacing one external device.
The use of a DIS system consists of making physical connections: connecting external devices to DIS and linking DIS modules together to make a complete bus, and sending the converted data to the S/5 monitoring system. The user can then select the source of measurement data for physiologic parameters displayed in the Datex-Ohmeda monitor.
The Device Interfacing Solution supports interfacing of the following device categories: ventilators/anesthesia machines, stand-alone monitors, blood gas analyzers and heart-lung machines.
The Device Interfacing Solution can interface numerical, waveform and event type of data from the external device. Alarms are not transferred.
Interfaced data can be displayed on the monitor screen, trended, printed and used for record keeping purposes. Also, interfaced physiologic data is sent to the network to be viewed at the Central station monitor.

{2}------------------------------------------------
### SUMMARY OF TECHNOLOGICAL CHARACTERITICS OF DEVICE COMPARED TO THE PREDICATE DEVICE as required by 807.92(a)(6)
The S/5TM Device Interfacing Solution is substantially equivalent in safety and effectiveness to the legally marketed (predicate) A.S/3 Interface Board, B-INT (K935477).
The S/5TM Device Interfacing Solution (later referred to as DIS) is an additional part of a Datex-Ohmeda modular S/5TM monitoring system. The Device Interfacing Solution enables connection of external medical bedside devices such as stand-alone monitors, ventilators/anesthesia machines, blood gas analyzers and heart-lung machines to the monitoring systems.
The DIS does not perform any physiological measurements itself. It receives data from connected external devices and transfers it in to the S/5TM monitoring system. The Datex-Ohmeda S/5TM monitor displays, trends and uses data for calculations and transfers it to the record keeping system and network accordingly. In terms of overall function, the S/5TM Device Interfacing Solution connected to an S/5™ monitoring systems is substantially equivalent in safety and effectiveness to the Datex-Ohmeda AS/3™ Interface Board, B-INT (K935477).
The S/5™ Device Interfacing Solution, in terms of general function is identical to its predicate AS/37M Interfacing board, B-INT (K935477). The S/5TM DIS simply extends the capability to interface more devices simultaneously, allows interfacing of different device types and also allows transfer of event type of data.
The concept of the S/5TM Device Interfacing Solution is the same as the predicate but the implementation differs slightly.
The predicate AS/3™ Interfacing board, B-INT (K935477) is a circuit board located in the frame of the monitor. It interfaces external medical devices such as monitors and anesthesia machines. One B-INT board includes drivers for the whole device library. The predicate B-INT is able to transfer numerical, waveform and alarm data from the interfaced device.
The S/5TM Device Interfacing Solution is a module that can be placed close to the interfaced external device. It interfaces external medical devices such as monitors, ventilators, anesthesia machines, blood gas analyzers and heart-lung machines. The module is device specific: a separate DIS module is needed to interface each external device. The DIS is able to transfer numerical, waveform and event type of data such as ventilator settings, laboratory results and heart-lung machine settings.
The S/5TM Device Interfacing Solution does not transfer alarms.
In summary, the S/5TM Device Interfacing Solution described in this submission is substantially equivalent to the predicate device.
{3}------------------------------------------------

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.
