#### Description:
The March Healthcare Health Monitoring Kit (HMK) is a portable medical device equipped with a built-in blood pressure monitor. pulse oximeter, and electronic stethoscope intended for spot-checking the basic vital signs of pediatric patients aged three and older and adult patients under the care of a physician in both clinical and home environments. The HMK can be used as a stand-alone unit or it can be connected to a host using a standard Bluetooth® wireless interface or wired universal serial bus (USB) interface to support remote control of the HMK and audio and data transmission in telehealth applications.
In both stand-alone and remote telehealth applications. the user can spot-check the following vital signs with the blood pressure monitor and pulse oximeter: heart rate and svstolic and diastolic blood pressure. and functional blood oxygen saturation and pulse rate. In remote telehealth applications when the HMK is interfaced with a host, the electronic stethoscope transmits heart and lung sounds via the host to a health care professional at a remote computer. The data from the HMK can be viewed in one of two wavs: on the built-in HMK liquid crystal display (LCD) or from a remote computer connected to a host.

{2}------------------------------------------------
The HMK blood pressure monitor uses the non-invasive, oscillometric, step-wise deflation method to measure heart rate and systolic and diastolic blood pressure. The noninvasive pulse oximeter measures functional blood oxygen saturation and pulse rate using a photodetector and a red and infrared light source to measure the absorption of red and infrared (IR) light passed through the tissuc and arterial hemoglobin. The electronic stethoscope uses a microphone within the chestpiece. bchind a diaphragm. The microphone converts the sound in the chestpiece to an clectronic signal for amplification and transmission to a health care professional at a remote computer via the host.
The HMK does not store physiological data in memory. When using the HMK as a standalone unit. the user must manually record the results displayed on the LCD. However. when the HMK is interfaced with a host, the host may store the audio and physiological data in a database for remote access by authorized clinicians.
The HMK is powered with either a Sealed Lead Acid (SLA) battery or a Medical Grade IEC 60601-1 compliant AC adapter. The AC adapter is also used to charge the SLA battery.
The HMK has only two external inputs: AC adapter input and universal serial bus (USB) input. The user connects the AC adapter to the DC power plug socket when the battery needs charging. In addition, the user can connect the HMK to the host using the Type B USB input as a wired alternative to the wireless Bluetooth interface.
The HMK is for sale by or on the order of a physician.
#### Intended for Use:
The March Healthcare Health Monitoring Kit (HMK) is a non-invasive, spot-measuring device intended to measure heart rate and systolic and diastolic blood pressure using the oscillometric method: functional oxygen saturation levels: pulse rate; and heart and lung sounds of both pediatric patients aged three vears and older and adult patients under the care of a physician in either clinical or home enviroments.
#### Technological Comparison to the Legally Marketed Devices:
Technologically, the March Healthcare HMK is substantially equivalent to the legally marketed devices listed above. The risks, safety and effectiveness, and benefits of the March Healthcare HMK are also comparable.

{3}------------------------------------------------
To highlight:
- The Non-Invasive Blood Pressure measurement specifications and performance . are equivalent to the Welch Allyn 52000 Vital Signs Monitor (K951193). The HMK and the Welch Allyn 52000 Vital Signs Monitor use a CAS Medical OEM NIBP module that is similar in design.
- The HMK SpO2 measurement and performance specifications are equivalent to . the Welch Allyn 52000 Vital Signs Monitor (K951193) because both units use Nonin OEM pulse oximetry technology.
- The heart and lung sound specifications and performance are derived from the . Cardionics stethoscope (K961301). The networked clectronic stethoscope is an added feature on the HMK that is not available on the Welch Allyn 52000. However, the stethoscope has been approved for market by the FDA to be incorporated into systems like the HMK: consequently, the inclusion of the FDAapproved stethoscope technology raises no new issues of safety and effectiveness and does not affect a substantial equivalence determination.
#### Materials and Biocompatibility:
The blood pressure monitor, pulse oximeter and electronic stethoscope modules are encased in an UL-approved acrylonitrile-butadiene-styrcne (ABS) injection molded carrying case.
The following components contact the patient:
- A & D Medical LifeSource Pressure Cuffs: The pressure cuff is made from cloth . material (6-nylon) and the cuff hose is made from latex-free PVC plastic.
- Nonin Pulse Oximeters: All oximeter sensors are constructed using materials that . have been previously validated by Nonin for biocompatibility per ISO 10993.
- Cardionics Stethoscope: The stethoscope chest piece is made from steel. .
These patient contacting materials have a history of biocompatibility with respect to patient contact. These materials contact the patient in the same locations for less or the same amount of time. Moreover. March Healthcare Corporation has not modified these materials in any way. A&D Medical. Nonin. and Cardionics have tested all patient contacting equipment and accessories for biocompatibility. and these manufacturers have obtained adequate biocompatibility results. For these reasons. March Healthcare Corporation believes that no further biocompatibility testing is required.

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.
