#### Device Description 4.
The Velox Nebulizer System is a portable, reusable, single-patient use, handheld electronic nebulizer that uses a piezo-driven, micro-perforated vibrating membrane technology to aerosolize liquid medications for the treatment or prophylaxis of respiratory diseases. It is to be used with adult and pediatric patients for whom doctors have prescribed medication, i.e. it is for prescription use only. It may be used in hospital-type facilities, nursing homes, sub-acute institutions and home environments. It is provided non-sterile.
The device consists of two major components. One of these components is the nebulizer itself, which has the following materials in its construction: (1) polypropylene: (2); thermoplastic elastomer; (3) stainless steel; (4) piezo-ceramic; (5) capton; and, (6) medical grade adhesives. It contains, as subcomponents, the following: (1) a medication cap, (2) a medication reservoir, (3) an aerosol head, (4) an aerosol chamber; and, (5) a mouthpiece.
The second major component is a Controller that is attached to the Nebulizer for its operation. This component, the body of which is constructed of acrylonitrile butadiene styrene and thermoplastic elastomer, has the following principal internal subcomponents: (1)
{4}------------------------------------------------
a circuit board: (2) a USB connector: (3) a patient interface (on/off switch); and (4) AA battery housing.
The controller's functions are to; (1) conduct power pre-processing; (2) supervise, through incorporated software, the nebulizer's aerosol generation; and, (3) generate optical and acoustical feedback to the user on nebulization status and out-of-range parameters.
The incorporated software is device-specific and: (1) controls the power to the aerosol head, i.e., either to have the aerosol head active and generate aerosol, or shut-off; (2) controls optical and acoustical feedback to the user; and; (3) is not dependent for its operation on any external devices, such as a monitor, printer, keyboard or mouse.
Energy sources for the device are provided by: (1) connection to a mains power source, via an AC Power Supply; or. (2) disposable/rechargeable AA batteries.
The device has two associated accessories: (1) a cleaning aid, branded VELOXcare, that assists in debris removal from the membrane prior to cleaning; and, as heretofore noted. (2) an AC Power Supply to provide mains power to the device when desired or required.
#### Mechanism of Action 5.
The Velox Nebulizer System's mode of action is permanent, i.e., once the on/off switch is on the controller pressed, permanent nebulization occurs until the medication is nebulized. There is no pause function. Further, there is no breath trigger or interrupter.
Nebulization is accomplished as follows. When the on/off button is pressed the controller sends an electrical charge to the aerosol head in the nebulizer. The charge alternation causes the piezo-actuator to vibrate. Vibration motion then builds up a positive pressure in the boundary layer of the liquid column, ejecting the fluid through the holes as droplets and creating the aerosol on the front side of the membrane. This aerosol is deposited vertically into the aerosol chamber. Once in the chamber it is available for inhalation by the patient.
The inhalation is via a breath-enhanced two-way valve system. During inhalation the inhalation valves open to allow fresh air to enter the aerosol chamber. This inhaled fresh air stream, takes the aerosolized medication, with minimum depositional loss, through the mouthpiece into the patient's respiratory tract. Note that, during inhalation, the exhalation valve on the mouthpiece is closed, preventing any aerosol dilution on its way to the patient. During exhalation, the inhalation valves close and the exhalation valve opens, driving the expired air out of the mouthpiece.
#### 6. Indications for Use
The Velox Nebulizer System is a handheld nebulizer that is to be used with patients for whom doctors have prescribed medication for nebulization. It is intended for adult and pediatric patients 4 years and older who can coordinate breathing through a mouthpiece, and may be used in hospitals, hospital-type facilities, nursing homes, sub-acute institutions and home environments.
The foregoing statement for the subject device is identical to that of the predicate eRapid® device (with the exception of the "4 years and older who can coordinate breathing through a mouthpiece" restriction. The indications are substantially equivalent; the subject device indication statement simply provides a quantification of patient age, and clarification of the patient's breathing
{5}------------------------------------------------
coordination ability at that age). Further, both the subject and predicate device have the same intended use.

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.
