Indications for Use
The Smartlock™ safety syringe is intended as a sterile, single use, disposable syringe to be used for injecting medications or fluids into the patient by attached cannula or via intravenous therapy, or to draw samples or fluids by the same means. Only once the medication has been administered or the sample taken, should the safety mechanism be activated. The intention of the safety mechanism is, after use of the syringe, to bring the needle within the safety shield in one motion and to lock it in that position. rendering the syringe unusable. The safety mechanism has no effect on the efficacy of the syringe in regard to its performing the function of a standard syringe. The 3ml, 5ml and 10ml Smartlock ™ syringes all function using the same principle and all have the same intended use. The Smartlock™ syringes are not intended to be used with syringe pumps. The appropriate warnings are printed on the syringe labeling.

#### Predicate Devices 3.
The Smartlock™ safety syringe is substantially equivalent to the Becton Dickinson Plastipak™ standard syringe in use.
The Smartlock™ safety syringe is also substantially equivalent to the Becton Dickinson Safety-Lok™ safety syringe
# Product Description 4.
The Smartlock™ safety syringe is a sterile, single use hypodermic syringe incorporating an innovative safety mechanism. It is designed to withdraw the needle into the safety shield after use and to lock it in this position.
Image /page/1/Figure/5 description: The image shows a black and white drawing of a syringe. The syringe has a needle on the left side and a plunger on the right side. The barrel of the syringe has markings that indicate the volume of fluid inside. The plunger is partially depressed, indicating that some fluid has already been expelled from the syringe.
# Smartlock™ Safety Syringe - 5ml
The Smartlock™ safety syringe is a slight departure from standard syringes in that whilst it consists of three parts i.e. a safety shield, a barrel and a plunger, there are differences in their design. There is no rubber piston. The syringe is packaged fully assembled and no set-up action or pre-use motion is necessary. Needles are attached in the standard luerslip method and can be changed during a procedure, if necessary. The materials used in production are medical grade polypropylene and polyethylene.
As the last of the medication is delivered, the plunger rim will disengage the safety clips from the shoulder. As the plunger is retracted (as if to refill), the needle will also retract. The plunger must be retracted fully until a "click" sound is heard and no movement is possible. Disposal is then simple and safe. The functioning of the 3ml, 5ml and 10ml Smartlock ™ Safety Syringes are identical in all respects, save the amount of fluid which can be aspirated.

# Clinical Trial 7.
Clinical trials were held in three South African hospitals to compare the Smartlock™ safety syringe to the Becton Dickinson Plastipak™ standard syringe. The primary hypothesis was that the Smartlock™ safety syringe would be substantially equivalent to the conventional syringe in respect of comparable characteristics.
The information collected was comprehensive and extremely detailed and included both the objective and subjective experiences of the participating nurses. Monitoring of the actual use of syringes by the nurses, was by experienced personnel and evaluation of the number of svringes which functioned successfully was by an independent auditor.
The results were largely clear cut. The nurses ranked both types of syringes similarly and positively, and this was confirmed by the monitors and the auditor. The Smartlock™ safety svringe proved substantial equivalence to the Plastipak™ syringe in use.
#### 8. Simulated Use Study
A simulated use study was conducted at three separate American hospitals. The Smartlock™ safety syringe was compared to the Becton Dickinson Safety syringe. The success rates in correctly using the Smartlock™ safety syringe did not significantly differ from the rates seen with the Becton Dickinson Safety svringe among nurses who received instruction from the package insert. When a verbal "inservice" training session was added, the Safety-Lok™ was scored at a slightly higher level,
The study documented that the Smartlock™ safety syringe is substantially equivalent to the Safety-Lok™ safety syringe with respect to the rates of correct usage. The study also documented that "in-service" training sessions prior to introducing the syringes to hospitals would enhance the rate of correct usage.

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.
