Indications for Use
The Nice1 combines cold and compression therapies. It is intended to treat post-surgical and acute injuries to reduce edema, swelling, and pain where cold and compression are indicated. It is intended to be used by or on the order of a healthcare professional in hospital, outpatient clinics, athletic training settings, or home settings.
Device Story
Nice1 is a cold and compression therapy system for post-surgical and acute injury recovery. The device consists of a control unit, hose assembly, and therapy wrap. The control unit uses thermoelectric technology to chill water in a 300ml reservoir and a pneumatic system to inflate/deflate the wrap. The user selects temperature (43°F–59°F) and compression (0–75 mmHg) via a graphical touch screen. The system circulates cooled water through the wrap while providing intermittent pneumatic compression. It is used in hospitals, clinics, athletic training settings, or homes by healthcare professionals or patients. The device benefits patients by automating cold and compression delivery to manage pain and swelling.
Clinical Evidence
No clinical testing data are submitted, referenced or relied on to determine substantial equivalence. Bench testing only.
Indicated for adults and children under 18 (under supervision of a healthcare practitioner) with post-surgical or acute injuries requiring cold and compression therapy to reduce edema, swelling, and pain.

| Device Description | Nice1 is a cold and compression therapy device used to aid<br>recovery and reduce pain associated with soft tissue injuries. The<br>device works by circulating cooled water and air through a<br>therapy wrap that is placed on the injured body part. The cooled<br>water circulates through the therapy wrap and provides cold<br>therapy; the air inflates the therapy wrap causing it to compress<br>around the injured body part. |
|--------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| | The Nice1 uses thermoelectric technology to chill the water.<br>The Nice1 consists of 3 key components:<br>1. The control unit which chills the water and contains the<br>pneumatic system for inflating and deflating the therapy<br>wraps.<br>2. The hose assembly which connects to the control unit to<br>the therapy wrap and provides conduits for the flow of<br>water and air to and from the therapy wrap.<br>3. The therapy wrap which is placed on the patient and<br>wraps around the injured body part to deliver cold and<br>compression therapy. |
| | The control unit is an electromechanical, software-controlled<br>device housed in a plastic enclosure. The device is approximately<br>8 x 7.64 x 8" and weighs 10 lbs. Inside the control unit are a<br>thermoelectric heat exchange for cooling the water, a pneumatic<br>system to control the flow of air to/from the therapy wrap to<br>regulate compression, and electronics to control the therapy.<br>Integrated into the plastic enclosure is graphical touch screen that<br>displays outputs and receives inputs from the user. Temperature,<br>compression levels and therapy duration are selected by the user<br>via the graphical touch screen interface and controlled by a<br>microprocessor. |
| | The control unit contains a 300ml reservoir that is filled with<br>water by the user. Water from the reservoir is cooled by passing<br>through the thermoelectric heat exchange; it is then pumped from<br>the control unit through the hose assembly, through the therapy<br>wrap and then returns to the control unit to be re-chilled.<br>Temperature is controlled in five (5) levels ranging in<br>temperature from 59°F to 43°F. |
| | Compression can be set at low, medium and high settings ranging<br>from 0 mmHg to 75 mmHg. The compression cycles from high<br>to low on 2 – 5 minute intervals to achieve Intermittent |
| | Pneumatic Compression. |
| | The hose assembly is 6 feet long and consists of a foam rubber<br>outer sheath to provide insulation and 3 urethane tubes that carry<br>water and air to/from the control unit and therapy wrap. |
| | The therapy wraps are comprised of 3 layers of urethane coated<br>nylon that are welded together to make 2 separate air and liquid<br>tight layers for the air and water. The therapy wraps are tailored<br>to fit specific body parts. At the current time the company is only<br>marketing a knee wrap. Therapy wraps use a Velcro closure to<br>allow for customized fitting for different patients. |

| Summary of Technological | Nice1 and Game Ready have substantially equivalent functions: |
|---------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Characteristics in | -Both devices pump cooled water through a hose and therapy |
| Comparison to Predicate | wrap that is placed on the injured body part of the patient. |
| | -Both devices inflate and deflate the therapy wrap and regulate air |
| | pressure to achieve Intermittent Pneumatic Compression. |
| | -Both devices use a microprocessor to control water temperature, |
| | compression levels and therapy duration. |
| | -Both devices have therapy wraps that correspond to specific |
| | body parts. |
| | -Both devices use therapy wraps that are comprised of 3 layers of |
| | urethane coated nylon that are welded together to make 2 separate |
| | air and liquid tight layers for the air and water. |
| | Nice1 differs from Game Ready in only 3 significant aspects: |
| | Nice1 uses thermoelectric technology to cool the water, so<br>1. |
| | the patient only needs to add water to the reservoir. Game |
| | Ready uses ice to cool the water, so the patient must fill |
| | the reservoir with both ice and water. |
| | 2.<br>Because Nice1 and Game Ready use different methods to |
| | cool the water (thermoelectric vs. ice) the devices use |
| | different water flow rates to maintain the same levels of |
| | cold therapy. The differing flow rates are completely |
| | transparent to the user as the user is only aware of the cold |
| | therapy which is identical regardless of the fact that the |
| | water is flowing at different rates inside of the system. |
| | 3.<br>Nice1 uses a graphical touch screen to display options and |
| | |
| | messages as well as receive inputs from the user. Game Ready uses physical dials, buttons and a liquid crystal display to display options and messages as well as receive inputs from the user. Both products have substantially equivalent functions and provide equivalent therapies. |
| Non-clinical Testing | Nice1 complies with AAMI ANSI ES60601-1:2005/(R)2012, AI:2012 general requirements for electrical safety and IEC 60601-1-2:2007 electromagnetic compatibility.<br>Substantial equivalence with the predicate device is supported by Performance testing. Performance data demonstrates comparable results for cold therapy and compression therapy. A summary of the testing results follows: |
| | 1. Cold Therapy: The Nicel and Game Ready operate at similar therapeutic temperatures. The coldest temperature for the Nice1 is 43 degrees F while the coldest temperature for Game Ready is 37 degrees F. |
| | The main difference demonstrated in non-clinical testing was that the Game Ready reaches cold temperatures quicker than Nicel because it uses ice to cool water. Ice has an almost instantaneous effect while the thermoelectric technology used by Nicel requires a cool-down time of approximately 5 – 10 minutes to reach the target low temperature. |
| | 2. Compression Therapy: Compression Therapy: The Nicel and Game Ready devices both operate at the same compression levels and cycle times. |
| | At the High setting: the Nicel inflated to 75 mmHg for 2.5 minutes and then deflated to 5 mmHg for 1 minute. The Game Ready inflated to 75 mmHg for 2.5 minutes and deflated to 5 mmHg for 1 minute. |
| | At the Medium setting: the Nicel inflated to 50 mmHg for 2.5 minutes and then deflated to 5 mmHg for 1 minute. The Game Ready inflated to 50 mmHg for 2.5 minutes and deflated to 5 mmHg for 1 minute. |
| | At the Low setting: the Nicel inflated to 15 mmHg for 4.5 minutes and then deflated to 5 mmHg for 1 minute. The |
| | Game Ready inflated to 15 mmHg for 4.5 minutes and<br>deflated to 5 mmHg for 1 minute. |
| Conclusions from Non-Clinical Testing | Testing demonstrates that the Nice1 is as safe, as effective, and performs as well as the Game Ready device. |
| Clinical Testing | No clinical testing data are submitted, referenced or relied on to determine substantial equivalence. |

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.
