# 5. General Description
The CLINITRON® RITE•HITE™ Air Fluidized Therapy Unit combines the best features of the predicate devices, CLINITRON ELEXIS® (K943385) and the CLINITRON AT•HOME® (K942184), in order to meet the design objectives. The intent of the design is to provide an economical combinational therapeutic support surface on a mobile articulating frame specifically for use in the Long Term Care setting. Another design objective was to provide this type of surface on a frame that would go as low as possible. The CLINITRON® RITE•HITE™ tank edge is at 21.5 inches in its lowest position. This will permit easier positioning and egress.
The combinational support surface includes both low airloss and air fluidized therapies. The upper half delivers low air loss therapy through low-friction support cushions which supports the upper half of the body (above the waist) and the lower half consists of air fluidized therapy which supports the lower half of the body (below the waist). This type of sleep surface is common to both the CLINITRON ELEXIS® and the CLINITRON AT•HOME®.
The CLINITRON® RITE•HITE™ Air Fluidized Therapy is intended for medical purposes to treat or prevent bedsores, to treat severe or extensive burns, or to aid in circulation. This bed will be an ideal support for patients who have advanced pressure ulcers, flaps, grafts, or burns, and require frequent transfers or variable head elevation and any other conditions appropriate for air-fluidized therapy. The bed also can be used for intractable pain, extensive epidermal detachment, Stevens-Johnson Syndrome, purpura fulminans, aid in infection control, induce relaxation which may reduce need for sedative and pain medication, improve patient outcome, and reduce wound healing time. The bed will permit easy positioning and egress, thereby enhancing the independence of residents.
# 5 Safety and Efficacy
The safety characteristics of this product compare to those of the predicate devices. No significant changes have been made which impact the safety and efficacy of the CLINITRON® RITE•HITE™ Air Fluidized Therapy Unit as compared to the predicate devices. There are no performance standards established for this classification.
# 6 Technological Characteristics
The air fluidization medium consists of silicon-coated glass microspheres. The microspheres sit on top of a diffuser board and are contained on the sides by an air wall bladder/cushion. An air permeable filter sheet separates the microspheres from the patient.
Pressurized air is delivered to the chamber under the diffuser board. Air enters the chamber, passes through the diffuser board, fluidizes the microspheres, and escapes through the filter sheet. Air to the chamber is heated or cooled as necessary.
A microprocessor controls the user's operations and controls and monitors the main components of the unit.

# C. Manufacturer's Statement of Substantial Equivalence
## 1. Substantially Equivalent Devices
The CLINITRON® RITE• HITE™ Air Fluidized Therapy unit is substantially equivalent to the following device:
The CLINITRON ELEXIS® Air Fluidized Therapy Unit (Model C-10) manufactured by Hill-Rom, Inc.
Classification number: INX (21 CFR Part 890.5160)
510 (k) #K914351
The CLINITRON® AT• HOME™ Air Fluidized Therapy Unit (Model C-6) Manufactured by Hill-Rom®, Inc.
Classification number: INX (21CFR Part 890.5160)
510(k) # K942184
## 2. Device Similarities
The subject device is substantially equivalent to the predicate device in the following aspects:
The CLINITRON® RITE• HITE™, CLINITRON® AT• HOME™ and the CLINITRON ELEXIS® provide a pressure relieving sleep surface for patients who need pressure ulcer treatment. Both devices are also of benefit to patients with other serious wounds such as post-surgical flaps.
The CLINITRON® RITE• HITE™, CLINITRON® AT• HOME™ and the CLINITRON ELEXIS® therapy units provide a pressure relieving sleep surface. Air fluidized therapy is used in the lower section; the vast majority of pressure ulcers occur from the waist to the heels.
Like the CLINITRON ELEXIS® and the CLINITRON® AT• HOME™, the CLINITRON® RITE• HITE™ unit fluidizes microspheres by passing pressurized air through a permeable diffuser board. The same microspheres, filter sheet fabric, and similar closure systems are used in both models.
The CLINITRON® RITE• HITE™ device uses cushions to provide a pressure relieving head section like the CLINITRON ELEXIS® and the CLINITRON® AT• HOME™. The cushion section of all the models allows an articulable head which assists with activities of daily living (feeding, reading, watching
{3}
television, etc.). The soft air wall, which is a feature of all three products, facilitates patient egress.
The CLINITRON® RITE• HITE™, CLINITRON® AT• HOME™ and CLINITRON ELEXIS® products have air cushions organized into zones which are continuously monitored to adjust the pressures when the patient reposition themselves or when the angle of head elevation is changed.
The CLINITRON® RITE• HITE™, CLINITRON® AT• HOME™ and CLINITRON ELEXIS® Therapy Units use identical cushion material and construction.
The CLINITRON® RITE• HITE™, CLINITRON® AT• HOME™ and CLINITRON ELEXIS® are operated and controlled by a microprocessor. The microprocessor allows the products to provide the caregiver with easy to operate functions and read-outs. The microprocessor allows constant monitoring and feedback for readjustments and servicing.
3. Device Differences
The predicate device differs in the following aspects:
The CLINITRON® RITE• HITE™ Air Fluidized Therapy unit has been designed for use and servicing in a long term care environment. The CLINITRON RITE HITE has operator controls which are appropriate for long term caregivers and the environment.
The CLINITRON ELEXIS® was designed as an acute care, hospital product with features suitable for use in an intensive care unit (ICU) and operation by trained medical personnel. Acute Care features found on the CLINITRON ELEXIS® but not on the CLINITRON® RITE• HITE™ include: CPR function which automatically deflates the cushions and lowers the head and frame; radiotranslucent plate and film tray for taking X-rays without removing patient from the bed; built-in scale for weighing patient; trendelenburg/reverse trendelenburg; oxygen tank holder.
The CLINITRON® AT• HOME™ unit makes use of new materials to create a light weight frame which can be easily transported and reassembled. The CLINITRON ELEXIS® has a frame constructed of steel and is transported on integral casters. The steel frame construction of the CLINITRON ELEXIS® permits the unit to have a high/low feature which raises the entire bed up and down. The CLINITRON® RITE•HITE™ uses the frame construction of the CLINITRON ELEXIS®, but is modified to provide a lower low position.
{4}
The CLINITRON® AT• HOME™ has a base with a wide footprint which distributes the weight of the unit across a large surface area. The combined weight reduction and wide footprint alleviates the concern for the structural integrity of older homes and trailers. The CLINITRON® RITE• HITE™ is not intended for use in homes, rather medical facilities.
The CLINITRON® RITE• HITE™ unit has a remote control with large head up/down buttons compared to the CLINITRON ELEXIS® unit which has smaller head up/down buttons built into the siderails. The large buttons on the CLINITRON® RITE•HITE™ remote control are easy for the elderly or disabled to operate.
The control panel of the CLINITRON® RITE• HITE™ has fewer functions and is much easier to understand than the CLINITRON ELEXIS®. Because the CLINITRON ELEXIS® Therapy Unit has more functions than the CLINITRON® RITE• HITE™, all corresponding hardware and software is more complicated.
In the event of a mechanical or electrical failure, the CLINITRON® AT• HOME™ unit shuts down, an audible alarm sounds, and a message shows on the control panel.
The CLINITRON ELEXIS® and the CLINITRON® RITE• HITE™, in the event of a failure, show a specific error message on the display screen and sounds an alarm. With the, the alarm can be silenced by pushing a button since trained medical personnel are taking responsibility for the patient and notifying Hill-Rom of the need for service.
The CLINITRON® RITE• HITE™ unit has four removable, siderails with a sliding bar locking mechanism. The CLINITRON ELEXIS® has four non-removable, collapsible siderails which lock in place by a spring loaded latch.
The CLINITRON® AT• HOME™ unit has a folding cover under the head assembly (similar to the hood of a baby carriage) to keep the family from misusing the area for storage or allowing pets to sleep on top of the base. The CLINITRON® RITE• HITE™ being an institutional product, does not require this feature.
Although these differences provide servicing and user benefits, none of the differences adversely affects the safety or efficacy of the device.

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.
