Indications for Use
The exhalation valves are intended to be used in ventilator circuits consistent with the indicated use of the ventilator to which they are attached. The single limb model directs flow and allows for pressure monitoring and may be used within hospitals and for home care use. The dual limb model regulates flow and is for use in hospitals and for home care use. The exhalation valve are used with adults, pediatrics, and neonates. The exhalation valves are for single patient use and can be used for a maximum of 30 days
Device Story
Altech® Exhalation Valves (Single and Dual Limb) function as components of ventilator circuits; they regulate gas flow and pressure. Operation relies on a control line (L port) receiving pressure from the ventilator; pressurization closes the valve during inspiration to deliver positive pressure to the patient; pressure release opens the valve during exhalation to vent gases. Single limb models exhaust expired gas through a bottom opening; dual limb models exhaust through the valve end. Used in hospitals and home care; operated by healthcare professionals or patients/caregivers per ventilator instructions. Single-patient use; maximum 30-day duration. Output is the regulation of circuit pressure and gas flow, enabling effective mechanical ventilation.
Clinical Evidence
Bench testing only. Performance evaluated via ISO 5356-1 (fittings), ISO 5367 (leakage <70 ml/min, resistance to flow), and ISO 18562 (particulates/VOCs). Biocompatibility confirmed via ISO 10993-5 (cytotoxicity), ISO 10993-10 (sensitization/irritation), and ISO 10993-11 (pyrogenicity/toxicity). Testing performed pre- and post-aging and after 30 days of simulated use.
Technological Characteristics
Non-rebreathing valve; 15/22 mm conical fittings (ISO 5356-1). Operates via pneumatic pressure from ventilator. Single and dual limb configurations. Non-sterile, single-patient use, 30-day lifespan. Materials evaluated per ISO 10993 and ISO 18562 standards.
Indications for Use
Indicated for use in ventilator circuits for adult, pediatric, and neonatal patients requiring mechanical ventilation in hospital and home care settings.
Regulatory Classification

#### Device Description:
The Altech® Exhalation Valves (Single Limb) are available in 2 configurations intended for use in Single and Dual Limb ventilator circuits. The difference between the configurations is location of exhaust of the expired gas to the room. In the Single limb, the valve is integrated to the limb and expired gas exhausts through the opening below the valve whereas in the valve is attached to the end of the exhalation limb and the expired gas exhausts through device end of the valve.
#### Principle of Operation:
Exhalation Valves have control line (L port) which passes the pressure from the ventilator to open or close the internal valve.
When starting to deliver an inspiratory breath, the ventilator pressurizes the exhalation valve, closing the exhalation path so that the positive pressure is delivered to the patient. At the end of inspiration, the pressure releases, the Exhalation valve gas pathway opens and the patient's exhaled gases then are vented to the room through the exhalation limb from device end of the valve for dual limb circuits or exhausted through the bottom opening of the valve for the single limb circuit.
#### Indications for Use:
The exhalation valves are intended to be used in ventilator circuits consistent with the indicated use of the ventilator to which they are attached.
The single limb model directs flow and allows for pressure monitoring and may be used within hospitals

and for home care use.
The dual limb model regulates flow and is for use in hospitals and for home care use.
The exhalation valve are used with adults, pediatrics, and neonates.
The exhalation valves are for single patient use and can be used for a maximum of 30 days
#### Patient Population:
Adult, Pediatric and Neonates on mechanical ventilation.
#### Environments of use:
They may be used with ventilators that are indicated for home settings. In all cases the Exhalation valves are part of the ventilator circuit and would be consistent with the indications of the ventilator to which they are attached.
#### Difference Between Subject and Predicate
Table 2 below presents the differences between the subject device and the predicate which are:
- Indications for use include the addition of neonate population and adding a Dual limb model in ● addition to the single limb model
- . The technological characteristics are similar between the subject device and the predicate in that they both use a valve which opened or closed by pressure that is applied by the ventilator. The only difference is that the predicate does not offer a dual limb design which connects to a dual limb circuit thus directing expired gases to the ventilator whereas the single limb design for both devices exhausts the expired gases to the room as they connect to a single limb circuit.
- . Performance and Specifications are similar and the differences in expiratory resistance and leakage are within acceptable ranges
- Patient population of adding Neonates
- The use of the subject device is dependent upon the ventilator to which it is attached and its O indications for 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.
