Description:
## System
The DS-5100E Patient Monitor System is a pre-configured monitor meant to acquire and monitor physiological signals from patients. The system is designed to be used in an ICU, CCU, OR, ER, or Recovery areas of a hospital or clinic. Battery operation allows the DS-5100E to be used to monitor patients being transported within the healthcare facility. Patient ages from neonates to adults can all be monitored. Waveforms, numeric, and trend data from these patients are available to the clinician on the system’s display or it may be printed on the system’s recorder.
The Fukuda Denshi model DS-5100E Portable Patient Monitoring system consists of a main unit and a power unit.
The main unit of the system can be remotely located from the power unit and connected via a cable to provide continuous AC power. Batteries are installed into the main unit and the power unit to allow both parts to be disconnected from AC power and still function. The main unit may also be disconnected from the power unit and function independently on battery power.
Small, lightweight, but powerful in its application of technology, the DS-5100E system is portable and extremely easy to use.
High speed RISC (Reduced Instruction Set Computing) microprocessors, along with a high resolution color display and touch screen technology has made the DS-5100E a unique and intuitive patient monitor.
Upgrade capability has been made simple and quick through the use of high speed flash memory.
A Recorder module (HR-500), a multi-parameter telemetry transmitter (HLX-501), and an IC memory card are available as options.
## Features
A 6 inch diagonal, active matrix TFT color display provides sharp, crisp waveforms and numerics.
A high quality, clear touch screen provides user interface that is simple and easy to use.
Up to 4 color waveforms can be displayed, measured and three can be recorded simultaneously on the optional HR-500 recorder.

Small and lightweight, the DS-5100E Main monitor unit is only 2.8 kg (6.2 lb.) with a battery, 5.1 kg (11 lb.) with the Power unit and 2 batteries.
Pre-configured monitoring parameters are ECG (3 leads), ST measurement, Arrhythmia, Respiration, 2 channels Invasive blood pressure, Non invasive blood pressure, Oxygen saturation, and 2 channels of Temperature.
Patient ages from neonates to adults can all be monitored by the DS-5100E.
High sample rates (1 second minimum) for graphic and tabular trend data provide highly accurate patient data.
Because there is no need for a cooling fan, operation is extremely quiet.
Use of low power, high speed flash memory allows for easy upgrades through a standard PCMCIA compatible IC card.
The AC power supply includes the battery charger for the built-in batteries, allowing the DS-5100E to be used during patient transport.
A recorder module (HR-500), a multi-parameter telemetry transmitter (HLX-501), and an IC memory card are available as options.

# Comparison to Predicate Device
In summary, the DS-5100E system is pre-configured and smaller version of the DS-5300 patient monitor. Changes to the system include a reduction in size and weight, pre-configured parameters, battery operation, and simplification of the display. A single, identical central processing unit simplifies the design while allowing the majority of the DS-5300 software to be used without modification. The majority of the changes can be summarized as pre-configured, smaller, and battery powered.
# Technological Characteristics
The DS-5100E utilizes a 6 inch TFT color LCD display with a high quality, analog touch screen. Physiological information is acquired through pre-configured inputs in a similar manner to the predicate device. A PCMCIA card interface provides a means to temporarily store data or to update the system's flash memory.
The pulse oximetry design is licensed from Nellcor Puritan Bennett and is the same as the Nellcor design used in the predicate device.
These technological differences do not affect the safety or efficacy of the device. Any safety issues that may be raised by a software controlled medical device are the same issues already addressed by the predicate device and are addressed in the systems hazard analysis and in the system validation.
# Testing:
Laboratory testing was conducted to validate and verify that the Fukuda Denshi model DS-5100E Portable Patient Monitor met all design specifications and was substantially equivalent to the FUKUDA DENSHI model DS-5300. This testing consisted of all environmental testing identified in the FDA's DCRND November 1993 "Reviewer Guidance Document for Premarket notification Submissions" Draft Guidance Document. Additional testing was performed to demonstrate compliance with the ANSI/AAMI standards ES1-1993, "Safe current limits for electromedical apparatus"; EC11-1991, "Diagnostic electrocardiographic devices"; and EC13-1992, "Cardiac monitors, heart rate meters, and alarms." Finally, a hazard analysis of the system and its software was performed and testing was conducted to validate the systems overall operation.

Testing of the non-invasive blood pressure portion of the DS-5000 series' system was conducted according to the requirements outlined in the ANSI/AAMI standards SP10-1992, "Electronic or automated sphygmomanometers." The results of this testing has been reviewed as part of the DS-5300's 510(k), K964187. Data presented here demonstrates that the DS-5100E system performs at least as well as the model DS-5300.
Testing of the pulse oximetry portion of the DS-5000 series' system was conducted according to Nellcor Puritan Bennett's testing protocol. The results of this testing has been reviewed as part of the DS-5300's 510(k), K964187. Data presented here demonstrates that the DS-5100E system performs at least as well as the model DS-5300.
Testing of the arrhythmia and ST Level portions of the DS-5000 series' system were conducted according to AAMI Recommended Practice ECAR-1987, "Recommended Practice for Testing and Reporting Performance Results of Ventricular Arrhythmia Detection Algorithms. The results of this testing has been reviewed as part of the DS-5300's 510(k), K964187. The data is reproduced in tabular format in the appendix.
Although the device is neither life supporting nor life sustaining, diagnostic information derived from the use of the device and alarms generated by the device may be critical to the proper management of the patient.
So, the areas of risk for this device are the same as the predicate device and other devices in this class, and are the following:
- Electrical shock
Excessive electrical chassis leakage current can disturb the normal electrophysiology of the heart, and possibly leading to the onset of cardiac arrhythmias.
- Misdiagnosis
- Inadequate design of the signal processing and measurement circuitry or program can lead to generation of inaccurate diagnostic data. If inaccurate diagnostic data are used in managing the patient, the physician may prescribe a course of treatment that places the patient at risk unnecessarily.
- Inadequate design of the device's software, used to make various measurements, can lead to generation of inaccurate diagnostic data. If inaccurate diagnostic data are used in managing the patient, the physician may prescribe a course of treatment that places the patient at risk unnecessarily.

{5}
- Inadequate design of the systems ability to alert the users through audible and visual indicators, can lead to user mistrust and/or inadequate response to the patient's condition. If an inadequate response to the patient's condition should occur the patient may unnecessarily be placed at risk.
The design of the DS-5100E has taken into account all the above. The device is designed to meet UL 601, CSA 22.2 and AAMI standards for electrical safety for medical equipment to prevent the possibility of excessive electrical leakage current to the patient.
## Conclusion:
The conclusions drawn from clinical and laboratory testing of the Fukuda Denshi model DS-5100E Portable Patient Monitor demonstrates that the device is as safe, as effective, and performs as well as or better than the legally marketed predicate device, the Fukuda Denshi model DS-5300 Patient Monitoring System.

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.
