Indications for Use
The eRapid NCP Nebulizer System is to be used with patients for whom doctors have prescribed medicine for nebulization. It is intended for adult and pediatric patients age 4 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.
Device Story
The eRapid NCP Nebulizer System is a portable, handheld electronic nebulizer for aerosolizing liquid medications. It consists of a controller and a nebulizer handset connected by a cord. The device uses micro-perforated vibrating membrane technology: a piezoelectric actuator, driven by an electronic circuit in the controller, vibrates a stainless steel membrane with laser-drilled holes against a fluid reservoir. This vibration creates liquid jets that disperse into a stream of droplets. The device is intended for use in hospitals, nursing homes, and home environments by patients or caregivers. The user initiates treatment via an On/Off button; the device operates continuously until the reservoir is empty, an error is detected, or a maximum time limit is reached. The controller provides audio-visual feedback regarding status and failures. By delivering medication as an aerosol, the device enables inhalation therapy for respiratory diseases, benefiting patients by facilitating targeted drug delivery to the lungs.
Clinical Evidence
No clinical data provided. Substantial equivalence is supported by bench testing, including aerosol performance (Total Output Rate, Mass Median Diameter, Fine Particle Fraction), biocompatibility, EMC/electrical safety (ANSI/AAMI ES60601-1, IEC 60601-1-2), software verification/validation, simulated use testing, and validation of cleaning/disinfection methods.

# 3. Legally Marketed Predicate Device
eRapid Nebulizer System, K112859
The following predicate device has not been subject to a design-related recall.
# 4. Device Description
2.
Both the eRapid NCP and the predicate eRapid device are identical in purpose, function, core technology and method of operation. They are single-patient use, reusable electronic nebulizers, using micro-perforated vibrating membrane technology to aerosolize liquid medications. They are for adult and pediatric inhalation therapy in a home care, nursing home, sub-acute institution, or hospital environment. The devices are hand-held and portable, consisting of a controller and a nebulizer handset, connected with a connection cord. Power input for both devices is provided by either AA batteries, or a DC or AC adapter. Alternate power cords, plugs and adapters allow their use in any country.
# 5. Mechanism of Action
The medication is filled into the medication reservoir of the nebulizer handset for presenting its liquid content to the vibrating membrane of the nebulizer to generate aerosol for inhalation. There is only the On/Off button on the controller to turn on the device, and start the treatment. When the treatment is done the device automatically shuts off.
This eFlow technology uses a wafer-thin plate or membrane of stainless steel, which is perforated with numerous laser-drilled holes (Figure 3). The size of the membrane holes determines the aerosol particle size. There is no other mechanism in place that changes the aerosol particle size, whether through software and/or user interface. This micro-perforated membrane vibrates at a high frequency against a body of fluid. The vibration source is the piezoelectric actuator that is activated by an electronic drive circuit of the Controller. The actuator and the perforated membrane are the main components of the aerosol head that is in contact
{4}------------------------------------------------
with the liquid medication to be aerosolized. Liquid jets are created as an inertial response to the vibration of the membrane. Surface tension and hydrodynamic effects then cause these jets to disperse to produce a stream of precisely controlled droplets.
Image /page/4/Figure/1 description: This image shows a diagram of a drug delivery system. The system consists of a reservoir containing the drug, electronics, a membrane with laser-drilled holes, a piezo actuator, and batteries. The drug is released as an aerosol through the laser-drilled holes.

7. Comparison of eRapid NCP Nebulizer system to the Predicate Device
{5}------------------------------------------------
{6}------------------------------------------------
{7}------------------------------------------------
### eRapid NCP Nebulizer System and Predicate eRapid Nebulizer system a.
Similarities are that both the eRapid NCP and the predicate eRapid device are identical in purpose, function, core technology and energy sources. That is, they are portable, reusable, single-patient use, handheld electronic nebulizers that use a piezo-driven, microperforated vibrating membrane technology to aerosolize liquid medications for the treatment or prophylaxis of respiratory diseases. They are to be used with adult and pediatric patients for whom doctors have prescribed medication, i.e. they are for prescription use only. They may be used in hospitals, hospital-type facilities, nursing homes, sub-acute institutions and home environments. Energy sources for the devices are provided by: (1) connection to a mains power source, via an AC Power Supply; or, batteries.
Both the eRapid NCP and the predicate eRapid employ breath enhanced, two-way valve systems. Further, both devices have permanent modes of action, i.e., once the on/off switch on the controller is pressed, continuous nebulization occurs until the medication is nebulized. Neither has any breath trigger or interrupter. Fluid delivery / generation for both devices is by direct contact between the aerosol head and the fluid in sealed medication reservoir.
The difference between the two devices are a 2nd generation eBase controller. The redesigned eBase Controller features: (1) Different housing design with a more modern user interface, (2) Integrated rechargeable battery pack, (3) Higher resolution LCD display, (4)
{8}------------------------------------------------
Adjustable settings for audio and visual features. In addition, The eBase NCP Controller will require a new Connection Cord and Power Supply.
Only the part of the Connection Cord that plugs into the eBase NCP Controller was modified. The other end of the Connection Cord, which is already part of the FDA-cleared device, has not been changed.
Differences from FDA-cleared device are thus confined to the new control unit, connection cord, and power supply.

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.
