# Device Description
KoKoMate is a hand-held, self-contained spirometer 31 with disposable mouthpiece designed specifically to measure a few simple expiratory spirometry values in the primary-care setting for diagnostic and screening purposes. The meter features a 4-line by 16-character LCD display; four control buttons; a port to accept its mouthpiece/flow-tube; and an IR data-transfer port.
The device measures expiratory breath flow through its mouthpiece, which is designed for single use. For a maximal expiratory effort, the meter determines peak expiratory flow (PEF), one-second forced expiratory volume (FEV1), six-second forced expiratory volume (FEV6), and average forced expiratory flow from 25 - 75% of total volume (FEF25-75%). It reports these values plus the ratio of FEV1/FEV6 and an indication of how these values compare to recognized predicted values. In addition, the meter processes the signals from each expiratory

maneuver to help determine the quality of the maneuver to aid the clinician or patient in determining whether the reported values are valid.
Along with the spirometer, the KoKoMate system can include one of two optional accessory products. These accessories act as data transfer conduits transferring data streams across optic and serial interfaces as they cradle the meter. One cradle is designed to couple the meter to a PC for data storage, printout, or analysis; the other links the meter directly to a printer for direct printout of a simple spirometry report.
#### Indications for Use
KoKoMate is a diagnostic spirometer for use in the primary-care setting to measure and report the following spirometric values: Peak Expiratory Flow (PEF), One-Second (FEV1) and Six-Second (FEV6) Forced Expiratory Volumes, Forced Expiratory Flow averaged from 25 - 75% of total volume (FEF25-75%), and the ratio of FEV1/FEV6.
### Summary of Technological Characteristics
The KoKoMate measures flow by pneumotachometry (using differential pressure across a known restriction to indicate air flow). The flow path in the meter is a single-use element mounted in pneumatic communication with a durable, reusable handle contains . sensors and associated electronics for interpretation, storage, display, and communication of flow data and test results. The handle houses the battery, pneumatic sensor, analog-to-digital converter, embedded microprocessor, control buttons, multiple-line alphanumeric display, and infrared data port.
Data communication between the meter and a PC or printer may be made through IR data ports on the meter and in one of the optional data-transfer accessories. Data transfer, storage, and display on a PC is done with an existing Windows-based spirometry program available from PDS. Control firmware embedded in the Printer/PC Cradle allows direct printing of the data stored in the meter in a simple report format.
# Summary of Non-Clinical Performance Data
# Safety
KoKoMate units were examined and bench tested by third-party examiners to demonstrate conformance to two recognized international consensus standards for safety of medical electrical equipment. The standards are EN 60601-1:1988 with amendments for general safety and EN 60601-1-2:1993 for electromagnetic compatibility.
#### Effectiveness
In-house and third-party testing, using an ATS-compatible automatic waveform generator. demonstrated that the measurement performance of the spirometer met or exceeded requirements published in the National Lung Health Education Program's consensus statement for office spirometry11 and in the American Thoracic Society's standard for diagnostic spirometry [2].
Meter function was also tested using specialized most-probable-error flow waveforms to validate measurement-quality features. The measurement-quality study demonstrated that the KoKoMate can appropriately provide information regarding a subject's PEF, FEV1, FEV6, FEF25-75%, and FEV1/FEV6 measurements and can identify measurements of suspect quality appropriately.

# Summary of Clinical Performance Data
Testing in a simulated primary-care setting demonstrated that patients and clinicians in that environment can safely and effectively use the KoKoMate under conditions of actual use and that the users guide, product physical design, and other human-factor characteristics of the KoKoMate system are appropriate for the product's intended use.
# Equivalence to Predicate Devices
The KoKoMate's design is a direct design enhancement of the AccuTrax predicate: using the same technologies, design principles, and manufacturing approach; but extending its features and accuracy. The system is substantially equivalent to the Spirovit SP-2: using the same measurement principles; using similar construction, material, and energy source; and meeting the same performance characteristics. The differences are that KoKoMate has a simpler user interface and reports a reduced set of spirometry values compared to the Spirovit.

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.
