To be used for temporary relief of pain associated with sore and aching muscles in the shoulder, waist, back, neck, upper extremities (arm), and lower extremities (leg) due to strain from exercise or normal household work activities.
Hand held, 1.5 volt AA battery powered, single mode, single function device with ten "settings" that are controlled by means of rotating a marked disk that increases the microcurrent when rotated clockwise and decreases the microcurrent when rotated counterclockwise, directly through the device integrated electrode into the indicated region of the body. The purpose of the Quick Relax Pro is to provide a temporary relief of minor muscle pain within the indicated region of the body.
The provided text describes a 510(k) summary for a medical device called "Quick Relax Pro," a transcutaneous electrical nerve stimulator (TENS) for pain relief.
However, the provided document does NOT contain information about acceptance criteria or a study proving the device meets specific performance criteria through clinical or analytical testing, especially not in the context of an AI/algorithm-based device as implied by the prompts' structured questions (e.g., ground truth, MRMC study, training sets).
This document focuses on:
- Device Identification and Classification: Name, applicant, contact, classification, product code, CFR reference.
- Predicate Device Comparison: Detailed comparison of the Quick Relax Pro to a legally marketed predicate device (HealthmateForever® Pro-8AB) in terms of intended use, technical characteristics (battery, isolation, output modes, waveform, software, functions), and specific parameters (voltage, current, pulse duration, frequency).
- Non-Clinical Testing: Mentions biocompatibility testing (ISO 10993-5, -10, -12), product safety testing (IEC 60601-1), and electromagnetic compatibility testing (IEC 60601-1-2). It states that the "results... were satisfactory, and serve to demonstrate the safety and effectiveness."
- Substantial Equivalence Argument: The core of the 510(k) submission, arguing that the Quick Relax Pro is substantially equivalent to the predicate device, emphasizing safety due to fewer features (no software, single mode).
- FDA Communication: The letter from the FDA stating their "substantial equivalence" determination and regulatory responsibilities.
Therefore, I cannot provide the requested information about acceptance criteria and specific performance study details for an AI/algorithm-based device because the document describes a hardware medical device (TENS unit) and its regulatory submission, not an AI or software algorithm that would involve the kind of performance studies, ground truth establishment, or training/test sets typically associated with AI/ML medical devices.
The acceptance criteria mentioned in the document are implicitly met by:
- Substantial Equivalence: The device is deemed safe and effective because its technological characteristics are substantially equivalent to a legally marketed predicate device.
- Compliance with Standards: Satisfactory results from non-clinical testing (biocompatibility, product safety, EMC) against established international standards (ISO, IEC).
There is no mention of:
- A table of acceptance criteria and reported device performance (in the context of AI/ML metrics like sensitivity, specificity, etc.)
- Sample sizes for test sets or data provenance (as no clinical performance study for an algorithm is described).
- Number of experts, their qualifications, or adjudication methods for ground truth.
- MRMC comparative effectiveness studies.
- Standalone algorithm performance.
- Type of ground truth (pathology, outcomes data, etc.).
- Training set size or ground truth establishment for a training set.
The document's structure is typical for a 510(k) premarket notification for a Class II medical device, focusing on comparison to a predicate and non-clinical safety testing, rather than an AI/ML clinical validation study.

The product is intended to remove dental plaque, stain, and discoloration from tooth surface etc. by dental professionals during dental treatment.
Both the predicate and the new proposed devices are operated by connecting to a standard turbine connection of a dental unit, which supplies air and water. The device is activated when the dental unit is activated and compressed air and water are supplied to the device. Air enters into the powder chamber where it is mixed with the prophylaxis powder. The mixture of air and water leaves the powder chamber and exits the distal end of the device through the spraying nozzle where the mixture of air and water is enveloped by water spray and directed onto the tooth surface. The mixture of air, water and powder removes dental plaque, stain and discoloration from tooth surface.

2. Sample Size Used for the Test Set and the Data Provenance
The 510(k) summary explicitly states: "No clinical tests were performed for the proposed device." Therefore, there was no "test set" in the context of clinical data used to prove device performance. The assessment of substantial equivalence was based on non-clinical testing and comparison of technological characteristics to the predicate device.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
As no clinical testing was performed and no test set was used, there were no experts involved in establishing ground truth for a clinical test set.
4. Adjudication Method for the Test Set
Since no clinical test set was used, there was no adjudication method employed.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done
No, a Multi Reader Multi Case (MRMC) comparative effectiveness study was not done. The 510(k) summary clearly states that no clinical tests were performed, which would include MRMC studies.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
The device is a dental handpiece, a mechanical tool, not an algorithm or AI system. Therefore, the concept of a "standalone" or "algorithm only" performance study is not applicable to this device.
7. The Type of Ground Truth Used
As no clinical tests were performed, no clinical ground truth (e.g., expert consensus, pathology, outcomes data) was established or used for the QUICK JET M in this 510(k) submission. The "ground truth" for demonstrating substantial equivalence was effectively the established performance and safety profile of the predicate device, AIR-FLOW handy 2 (K022119), as assessed through non-clinical comparisons of technological characteristics.
8. The Sample Size for the Training Set
The device is a mechanical dental handpiece, not a machine learning or AI algorithm. Therefore, the concept of a "training set" is not applicable.
9. How the Ground Truth for the Training Set Was Established
As the concept of a training set is not applicable to this device, there was no ground truth established for a training set.

The QuickVue Influenza Test allows for the rapid, qualitative detection of influenza type A and type B antigens directly from nasal swab, nasal aspirate, and nasal wash specimens. The test is intended for use as an aid in the rapid diagnosis of acute influenza virus infection. The test is not intended to detect influenza C antigens. Negative test results should be confirmed by cell culture; they do not preclude influenza virus infection and should not be used as the sole basis for treatment or other management decisions. The test is intended for professional and laboratory use.
The QuickVue Influenza Test involves the extraction of influenza A and B viral antigens. The patient specimen is placed in the Extraction Reagent Tube, during which time the virus particles in the specimen are disrupted, exposing internal viral nucleoproteins. After extraction, the Test Strip is placed in the Extraction Reagent Tube where nucleoproteins in the specimen will react with the reagents in the Test Strip. If the extracted specimen contains influenza antigens, a pink-to-red Test Line along with a blue procedural Control Line will appear on the Test Strip indicating a positive result. If influenza type A or type B antigens are not present, or are present at very low levels, only a blue procedural Control Line will appear.
The provided text contains information about a 510(k) submission for the QuickVue® Influenza test. However, it does not contain acceptance criteria or detailed study results that would allow for a complete description as requested. The document primarily focuses on establishing substantial equivalence to a predicate device and includes a brief analytical study for H7N9 detection.
Here's an analysis based on the available information, noting what is missing:
1. Table of Acceptance Criteria and Reported Device Performance
This information is not provided in the given text. A typical 510(k) summary for a diagnostic test would include sensitivity, specificity, and potentially positive and negative predictive values, along with their acceptance criteria. The document only mentions a "minimum detectable level" for H7N9.
Acceptance Criteria (e.g., Sensitivity, Specificity, LoD) | Reported Device Performance |
---|---|
Not specified in document | Not specified in document |
Minimum detectable level for Influenza A (H7N9) | 1.98 x 10^7 EID50/mL |
2. Sample Size Used for the Test Set and Data Provenance
The document describes an "analytical study" to assess the ability to detect H7N9 and establish the Limit of Detection (LoD). It does not specify a sample size for this analytical study.
- Sample Size for Test Set: Not explicitly stated for the analytical study mentioned.
- Data Provenance: Not specified, but given it's an "analytical study" focused on LoD, it typically involves prepared samples (e.g., spiked samples or known concentrations of virus) rather than patient specimens. The document doesn't mention a clinical study with patient samples.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This information is not provided in the document. For an analytical study establishing Limit of Detection, ground truth is typically established by the known concentration of the analyte in the prepared samples, not by expert review of test results. If a clinical study were performed (which is not described in detail here), expert-adjudicated ground truth might be relevant.
4. Adjudication Method for the Test Set
This information is not provided. Given that the described study is analytical to determine LoD, an adjudication method for test interpretation by multiple readers is not relevant. The result (presence/absence of a test line) is read directly from the test strip.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done, If So, What Was the Effect Size of How Much Human Readers Improve with AI vs Without AI Assistance
This is not applicable and not mentioned. The QuickVue® Influenza test is a visual, qualitative immunoassay designed for direct interpretation, not an AI-assisted diagnostic device where human readers interact with AI.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
This is not applicable. The QuickVue® Influenza test is a lateral flow immunoassay that requires human interpretation of visual lines for a positive or negative result. It does not involve an algorithm working independently.
7. The Type of Ground Truth Used
For the analytical study mentioned (LoD for H7N9), the ground truth would be based on the known concentration of the H7N9 virus in the prepared samples used to determine the detection limit.
- Type of Ground Truth: Known viral concentration (for the LoD study).
8. The Sample Size for the Training Set
This information is not provided. For a rapid immunoassay like the QuickVue® Influenza test, there isn't typically a "training set" in the machine learning sense. Assay parameters are optimized through biochemical development and analytical testing.
9. How the Ground Truth for the Training Set Was Established
This information is not applicable as there is no mention of a "training set" in the context of an AI/machine learning algorithm for this device. For the development and optimization of such an immunoassay, the "ground truth" during development would be established through careful analytical studies using known positive and negative samples, and samples with known concentrations of the target analyte.

The Quick Sampler Holder is intended to be used as a part of vacuum blood collection equipment for the collection of blood samples for various types of blood tests
The Quick Sampler Holder is a non-contacting patient device. It is intended to be used in conjunction with a vacuum blood collecting vessel and bloodlines with y-ports, for blood banking. The Quick Sampler Holder consists of a double ended 18 gauge needle attached to a blood tube holder. The proximal needle tip, which is inserted into the yport, is blunt to prevent accidental needlesticks; the distal end, inside the holder, is sharp and is covered by a rubber sleeve to prevent blood loss during vial replacement/sample collection.
The provided text is a 510(k) summary for the Nipro Quick Sampler Holder, which is a medical device for blood specimen collection. This document does not describe a study using a device that meets specific acceptance criteria in the way a clinical trial or algorithm performance study would.
Instead, it's a regulatory submission demonstrating substantial equivalence to a predicate device (ITL Samplok Luer Kit, K021941) based on non-clinical performance testing. Therefore, most of the requested information regarding ground truth, expert consensus, MRMC studies, and sample sizes for test/training sets is not applicable to this type of submission.
Here's a breakdown of the available information based on your request, with an explanation of why certain categories are not applicable:
1. A table of acceptance criteria and the reported device performance
The document lists "Performance characteristics" that were tested, but it does not provide specific numerical acceptance criteria or detailed reported performance values for each characteristic. It only states that the device was found to be "substantially equivalent" based on these tests.
Acceptance Criteria Category | Reported Device Performance (Summary) |
---|---|
Integrity test of tamper sealing | Not specified (implied to have met requirements for substantial equivalence) |
Rubber sleeve functional tests | Not specified (implied to have met requirements for substantial equivalence) |
Hub-needle functional tests | Not specified (implied to have met requirements for substantial equivalence) |
Hub-Holder functional tests | Not specified (implied to have met requirements for substantial equivalence) |
Chemical characteristics | Not specified (implied to have met requirements for substantial equivalence) |
Microbiological characteristics | Not specified (implied to have met requirements for substantial equivalence) |
Dimensional characteristics | Not specified (implied to have met requirements for substantial equivalence) |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
This information is not provided in the document. The document refers to "non-clinical tests" but does not detail the methodology, sample sizes, or provenance of materials used for these tests. The tests would likely be performed in a lab setting, not involving human subjects or data from a country of origin in the way a clinical study would.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This is not applicable. Ground truth, expert consensus, and expert qualifications are relevant to studies involving diagnostic accuracy or classification tasks, typically for AI/ML devices or clinical trials. This submission focuses on the mechanical and functional performance of a blood collection device through non-clinical testing.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This is not applicable. Adjudication methods are used in studies where human readers interpret data (e.g., medical images) and their agreement or disagreement needs to be resolved to establish ground truth. This is a non-clinical device performance submission.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
No such study was done. This is a medical device for blood collection, not an AI/ML-powered diagnostic tool, and the submission explicitly states "No clinical testing required or submitted with this application."
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This is not applicable. This describes a physical medical device, not an algorithm.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
This is not applicable. The "truth" for these non-clinical tests would be defined by engineering specifications, material standards, and performance metrics (e.g., seal integrity, dimensions, functionality checks) rather than expert consensus on a clinical outcome or pathology.
8. The sample size for the training set
This is not applicable. There is no "training set" as this is not an AI/ML device.
9. How the ground truth for the training set was established
This is not applicable. There is no "training set" as this is not an AI/ML device.
Summary of Device and Acceptance:
The Nipro Quick Sampler Holder's acceptance by the FDA (as indicated by the 510(k) clearance) is based on demonstrating substantial equivalence to a predicate device (ITL Samplok Luer Kit, K021941) through non-clinical performance characteristics testing. The key difference between the Quick Sampler Holder and its predicate is a blunt proximal tip versus a luer tip.

Metric | Acceptance Criteria (Implicit) | Reported Device Performance |
---|---|---|
Agreement with Methadone-Positive Clinical Specimens | >99% agreement with Behring EMIT II and GC/MS | 49 out of 49 correctly identified (100% agreement) |
Agreement with Methadone-Negative Clinical Specimens | >99% agreement with Behring EMIT II and GC/MS | 60 out of 60 correctly identified (100% agreement) |
Overall Agreement (Independent Labs, Professional Users) | High agreement to demonstrate reliability | >98% overall agreement (47/49 positive, 60/60 negative) |
2. Sample Size Used for the Test Set and Data Provenance
- Positive Samples: 49 methadone-positive urine specimens
- Negative Samples: 60 methadone-negative urine specimens
- Data Provenance: The document states "clinical sample kit comparison study, using 49 methadone-positive urine specimens and 60 methadone-negative urine specimens." This indicates the data is from retrospective clinical specimens. There is no specific country of origin mentioned, but the manufacturer is based in San Diego, California, USA, implying the studies were likely conducted within the US.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
The ground truth was established using laboratory methods rather than human expert interpretation of the device's results.
- Number of Experts: Not applicable in the traditional sense, as the ground truth was derived from analytical methods.
- Qualifications of Experts: Not specified, but the methods used (Behring EMIT II and GC/MS) are standard laboratory techniques that would be performed by qualified laboratory personnel.
4. Adjudication Method for the Test Set
The ground truth was established by comparison to two established laboratory methods: Behring EMIT II and GC/MS. While not an "adjudication" in the sense of multiple human readers, the use of two independent, highly regarded analytical methods served as the authoritative reference.
- Adjudication Method: Comparison to Behring EMIT II and Gas Chromatography/Mass Spectrometry (GC/MS). GC/MS is explicitly stated as "the preferred confirmatory method."
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No. The study described is a performance evaluation of a rapid immunoassay device against established laboratory methods. There is no mention of human readers evaluating cases with and without AI assistance (as the device itself is a standalone immunoassay, not an AI assisting human interpretation).
6. Standalone Performance
Yes, a standalone performance study was done. The QuickScreen™ Methadone Screening Test is an "algorithm only" device in the sense that it provides a direct qualitative result (positive/negative) based on a chemical reaction, without human interpretation of complex images or data needing AI assistance. The performance reported directly reflects the device's ability to classify samples on its own.
7. Type of Ground Truth Used
- Type of Ground Truth: Analytical laboratory results from established methods. Specifically, Behring EMIT II (an immunoassay) and Gas Chromatography/Mass Spectrometry (GC/MS) (a highly specific and sensitive confirmatory method).
8. Sample Size for the Training Set
The document does not explicitly mention a separate "training set" or "validation set" in the context of machine learning. As a rapid immunoassay, the device's "training" refers to its design and calibration, not a machine learning model. The study described is a performance evaluation using clinical samples.
- Sample Size for Training Set: Not applicable or not specified in this type of device evaluation.

3. Number and Qualifications of Experts for Ground Truth:
The document does not explicitly state the number or qualifications of experts used to establish ground truth for the test set.
4. Adjudication Method for the Test Set:
The adjudication method is not mentioned. The primary comparison is against a "predicate device" (Behring EMIT II) for the clinical samples and through "blind-labeled spiked samples."
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
A multi-reader multi-case (MRMC) comparative effectiveness study was not explicitly mentioned. The study focuses on the device's performance against a predicate device and spiked samples, not on human reader improvement with or without AI assistance.
6. Standalone Performance Study:
Yes, a standalone performance study was done. The "clinical sample correlation study and a blind-labeled spiked sample study" evaluate the QuickScreen™ Barbiturates Screening Test's performance independently, comparing its results to a ground truth (either the predicate device's results or the known concentrations in spiked samples).
7. Type of Ground Truth Used:
- Clinical Sample Correlation Study: The ground truth was established by another "commercially available test" – the Behring EMIT II. This is a form of comparative ground truth against an established method.
- Blind-Labeled Spiked Sample Study: The ground truth was based on known concentrations of barbiturates in the "spiked samples." This represents a form of analytical ground truth.
8. Sample Size for the Training Set:
The document does not provide information about a separate training set or its sample size. The studies described appear to be validation or performance evaluation studies, not explicitly detailing a training phase for a learning algorithm.
9. How Ground Truth for Training Set Was Established:
As no training set is explicitly mentioned, the method for establishing its ground truth is not provided. The device described uses "basic immunochemical sandwich assay principle," which is a traditional laboratory method and does not typically involve machine learning requiring a "training set" in the modern sense.
