The Jumao JM-P50A Portable Oxygen Concentrator provides a high concentration of supplemental oxygen to adult patients (ages 22 and older) requiring respiratory therapy on a prescriptive basis. It may be used in the home or in professional healthcare facility.

Portable Oxygen Concentrator, model: JM-P50A is a portable oxygen generator that is intended to release oxygen for respiratory therapy by physical means (a molecular sieve). It supplies a pulsed high concentration of oxygen and is used with a nasal cannula (supplied separately) to channel oxygen from the concentrator to the patient. The JM-P50A is small, portable and may be used in the home or in a professional healthcare facility.

Portable Oxygen Concentrator, model: JM-P50A, uses molecular sieve/pressure swing adsorption technology. Ambient air is drawn through particle filters by a compressor and forced through molecular sieve beds, which adsorb nitrogen and allow oxygen to pass. The airflow is then changed, and nitrogen is desorbed from the molecular sieve, allowing it to adsorb again during the next cycle. Oxygen is collected in an air tank. Waste nitrogen is exhausted back into the room. A series of sieve beds, manifolds and precision valves, sensors and embedded software are used to control the cycle to make the system function.

Portable Oxygen Concentrator, model: JM-P50A, can be used in the home or in a professional healthcare facility. Power options include 100 – 240 V (50- 60Hz) AC power supply, rechargeable battery packs.

Oxygen is delivered to the patient on a pulse dose basis in precise amounts during the inhalation part of the breathing cycle. This conserver technology eliminates waste of unused oxygen at other times in the breathing cycle when it is not needed. Portable Oxygen Concentrator, model: JM-P50A, senses the beginning of the inhalation cycle and releases a specified dose of oxygen enriched gas from the accumulator reservoir, through a final filter, into the connected nasal cannula and on to the patient.

The portable oxygen concentrator consists of main unit, battery, power adapter and carry case. The main gas pathway of oxygen concentrator is composed of particle filter, particle filters, air compressor, molecular sieve beds, manifold valve, sensors, air tank.

This is a 510(k) clearance letter for a Portable Oxygen Concentrator (JM-P50A). The document primarily focuses on demonstrating substantial equivalence to a predicate device (Inogen Rove 6 Portable Oxygen Concentrator) through bench testing and compliance with recognized consensus standards. It explicitly states that "There was no clinical testing performed."

Therefore, the provided document does not contain information about acceptance criteria and a study proving the device meets those criteria in the context of clinical performance or human-in-the-loop assessment. The information you're asking for, particularly points 1-7 from your prompt, typically applies to studies proving clinical effectiveness or diagnostic accuracy of AI/software as a medical device (SaMD), which is not the case here.

However, I can extract information related to the device's technical specifications and how its performance was evaluated against standards, which serve as a form of acceptance criteria for this type of device.

Here's an interpretation based on the provided document, addressing what can be extracted and noting what cannot be:

Acceptance Criteria and Device Performance for Portable Oxygen Concentrator (JM-P50A)

Based on the provided 510(k) clearance letter, the acceptance criteria and the "study" (bench testing and standards compliance) focus on demonstrating substantial equivalence to a predicate device and adherence to recognized performance and safety standards. There was no clinical testing performed for this device.

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria are primarily derived from the performance specifications of the predicate device and the requirements of various international standards. The "reported device performance" refers to the JM-P50A's demonstrated capability to meet these criteria through bench testing.

2. Sample size used for the test set and the data provenance

• Sample Size for Test Set: The document does not specify a "sample size" in terms of patient data or a test set as would be used in an AI/clinical study. The evaluation was based on bench testing of the device prototype/production unit(s) against engineering specifications and international standards.
• Data Provenance: The data provenance for performance testing originates from bench testing conducted by the manufacturer and/or accredited testing laboratories to demonstrate compliance with standards. The country of origin of the device manufacturer is China (Jiangsu Jumao X-Care Medical Equipment Co., Ltd.). The data is prospective in the sense that it's generated from testing the new device.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. This was not a study involving human interpretation or clinical data where expert ground truth would be established. The "ground truth" here is the established scientific and engineering principles underpinning device performance, as codified in international standards and the performance of the predicate device.

4. Adjudication method for the test set

Not applicable. No human adjudication was involved as this was not a clinical or AI performance study requiring human interpretation consensus.

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

Not applicable. This device is a medical hardware device (portable oxygen concentrator), not an AI/software-driven diagnostic tool that assists human readers. The document explicitly states: "There was no clinical testing performed."

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This is not an AI/algorithm-based device in the context of diagnostic performance. The device has "embedded software" that controls its functional cycle, and this software was verified and validated against IEC 62304 and FDA guidance, but this is distinct from an AI generating diagnostic outputs.

7. The type of ground truth used

The "ground truth" in this context is established by:

• International Consensus Standards: e.g., ISO 80601-2-67, ISO 80601-2-69, ANSI AAMI ES60601-1, IEC series, ISO 18562 series. These standards define accepted performance limits and test methodologies for portable oxygen concentrators.
• Predicate Device Specifications: The performance characteristics of the legally marketed predicate device (Inogen Rove 6 Portable Oxygen Concentrator) serve as a benchmark for demonstrating substantial equivalence.

8. The sample size for the training set

Not applicable. This device does not use machine learning or AI that requires a "training set" of data in the typical sense.

9. How the ground truth for the training set was established

Not applicable, as there is no "training set" for AI/ML in this context.

The provided FDA 510(k) clearance letter and its associated summary for the Neodent Implant System - Zirconia Implant System contain extensive information about the device, its intended use, and comparisons to predicate devices. However, it does not include specific acceptance criteria with numerical thresholds directly stated within the tables, nor does it detail a study that directly proves the device meets such criteria in terms of performance metrics like sensitivity, specificity, or image quality assessments.

Instead, the submission focuses on demonstrating substantial equivalence to predicate devices through various tests, implying that if the new device performs similarly to or better than previously cleared devices, it meets the necessary standards. The performance testing section describes the types of tests conducted (e.g., dynamic fatigue, torsion, insertion, pull-out, and software validation), but it does not present clear quantitative acceptance criteria or the specific performance results in a comparative table format.

Therefore, many of the requested fields cannot be directly extracted from the provided text as they pertain more to the performance evaluation of AI/software in interpreting medical images, which is not the primary focus of this dental implant submission.

Here's an attempt to answer the questions based on the available information, noting where information is not explicitly provided in the document:

Acceptance Criteria and Device Performance Study for Neodent Implant System - Zirconia Implant System

The FDA 510(k) summary for the Neodent Implant System - Zirconia Implant System focuses on demonstrating substantial equivalence to predicate devices through a combination of bench testing, software validation, MRI compatibility, biocompatibility, and sterilization validation. It does not present specific quantitative acceptance criteria or performance metrics directly from a comparative study in the way one might expect for an AI/software-based medical device (e.g., sensitivity, specificity thresholds). Instead, the "acceptance criteria" are implicitly met by demonstrating that the proposed devices perform at a level substantially equivalent to legally marketed predicate devices under standardized testing conditions.

1. A table of acceptance criteria and the reported device performance

As mentioned, explicit numerical acceptance criteria and reported device performance in a comparative table (e.g., for diagnostic accuracy) are not provided in this 510(k) summary. The summary indicates that tests were conducted according to relevant ISO standards and FDA guidance, and the results demonstrated that the subject devices exhibit a level of performance substantial equivalent to the predicate and reference devices.

Below is a conceptual table based on the types of tests mentioned, noting that specific numerical acceptance criteria and performance data are not detailed in the provided text.

2. Sample size used for the test set and the data provenance

The document details various bench tests (dynamic fatigue, torsion, insertion, pull-out) and validation studies (software, MRI, biocompatibility, sterilization, endotoxin, shelf-life). However, specific numerical sample sizes ("n=") for these individual tests are not provided in the summary. For example, for dynamic fatigue testing, it states "the results demonstrated that...". It doesn't specify how many implants or setups were tested.

• Data Provenance (Country of Origin): The submitter is JJGC Indústria e Comércio de Materiais Dentários S.A. (dba Neodent) based in Curitiba, Paraná, Brazil. The tests are generally conducted to international ISO standards and FDA guidance, but the location where the tests were performed is not explicitly stated for each test beyond the company's Brazilian location.
• Retrospective or Prospective: Not applicable in the context of bench testing and validation studies as described. These are laboratory-based tests rather than clinical studies on patient data.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

This information is not applicable and not provided in the context of this 510(k) submission. The device is a dental implant system (hardware), not an AI/software device that interprets medical images requiring expert-established ground truth for a test set. The validation processes involve standardized engineering and biological tests as opposed to expert review of clinical cases.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

This information is not applicable and not provided. As explained above, the submission pertains to a hardware device, not an AI/software system requiring human adjudication for ground truth establishment.

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 information is not applicable and not provided. This type of study is relevant for AI-assisted diagnostic tools, not for dental implant hardware.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This information is not applicable and not provided. This concept is specific to AI/software performance, not a physical dental implant system. The "software validation" mentioned is for the compatibility of milling units (CAD/CAM workflow), ensuring design parameters are respected, not for an AI algorithm interpreting dental images.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

For the bench tests, the "ground truth" is defined by compliance with established engineering standards (e.g., ISO 14801 for dynamic fatigue) and specifications (e.g., material properties, dimensions). For biological safety, it's compliance with ISO 10993. For the CAD/CAM software, it's the accurate adherence to design parameters. This isn't "ground truth" in the diagnostic sense, but rather adherence to predefined engineering and biocompatibility specifications.

• Clinical Literature Review: A clinical literature review was conducted to support the safety of Zi Transmucosal Implant less than 7mm of length, referencing animal studies and histomorphometry evaluation. This aligns with outcomes data or pathological/histological evidence from preclinical studies, suggesting "similar osseointegration outcomes" and "ability to promote bone formation around them in a manner equivalent to titanium implants."

8. The sample size for the training set

This information is not applicable and not provided. This concept is specific to machine learning/AI models, which are not the subject of this 510(k) submission.

9. How the ground truth for the training set was established

This information is not applicable and not provided. As above, this is relevant for AI/ML training data, not for a physical dental implant system.

The device also has an integrated safety mechanism that is designed to automatically generate a partial occlusion of the internal fluid path and trigger the hemodialysis machine to alarm and shut off if a complete dislodgement of the venous needle from the arm inadvertently occurs. In vitro testing supports that this feature triggers the hemodialysis machine to alarm and shut off.

The subject device is the JMS CAVEO A.V. Fistula Needle Set (CAVEO) with an anti-needlestick safety feature. The Caveo is predicted to protect patients from the risks associated with venous needle dislodgement (VND) based on bench testing results. It contains an integrated stainless steel torsion spring mechanism and bottom footplate that provides an open/fluid path when the AV fistula set is fully cannulated into the access site. When the venous needle becomes completely dislodged from the patient's arm, this mechanism enables the footplate to partially occlude the blood path, generating an increased venous line pressure high enough to trigger automatic alarm and halt further blood pumping of the hemodialysis machine. In vitro testing supports that this feature triggers the hemodialysis machine to alarm and shut off. Based on bench testing results, this may significantly reduce patient blood loss in the event of a complete VND. The Caveo has a pre-attached anti-stick needle guard for prevention of needlestick injury at the time of needle withdraw after completion of a hemodialysis procedure.

In vitro performance testing using dialysis machine Fresenius 2008K supports the function of the Caveo VND feature with a venous pressure limit set to 200mmHg symmetric mode, a maximum dialyzer membrane surface area of 2.5 m2, minimum blood flow rate of 200 mL/min, maximum ultrafiltration rate of 4000 mL/hour, and simulated treatment duration of 8 hours. If different machine and/or setting are used, before introducing the device, refer to Directions for Use.

This document describes the FDA 510(k) clearance for the JMS CAVEO A.V. Fistula Needle Set. This device is a physical medical device, specifically a needle set for hemodialysis, and does not involve Artificial Intelligence (AI). Therefore, many of the requested criteria related to AI/software performance, ground truth establishment, expert adjudication, MRMC studies, and training datasets are not applicable.

The document primarily focuses on bench testing (in vitro performance) and a simulated clinical usability study to demonstrate device safety and effectiveness.

Here's a breakdown based on the provided text:

1. Acceptance Criteria and Reported Device Performance

The acceptance criteria are primarily demonstrated through various performance tests, with "Passed" as the acceptance. The document doesn't explicitly state numerical acceptance thresholds for all tests (e.g., how much "Force to Depress the Footplate" is acceptable), but it implies successful completion. For some, like needle penetration resistance and retraction lock strength, numerical criteria are provided.

2. Sample Size for Test Set and Data Provenance

• Test Set (Clinical Trial): 15 subjects (2 females, 13 males).
• Data Provenance: The document does not explicitly state the country of origin. It describes the recruitment from "the general hemodialysis population," and mentions racial/ethnic demographics, but not geographic. Given the company is "JMS North America Corporation" (Hayward, CA), it is highly probable the study was conducted in the US. The study appears to be prospective as it involves recruitment and device use to confirm safety, performance, and usability.

3. Number of Experts Used to Establish Ground Truth and Qualifications

This question is largely not applicable as the device is a physical medical device. The "ground truth" for performance is established through bench testing (objective physical measurements) and the success of the device in a simulated clinical setting. There is no mention of human experts establishing a "ground truth" for diagnostic or AI-related interpretations.

For the simulated clinical usability study, the "ground truth" is whether the device performed as intended and was usable, as observed by clinicians/researchers during the study. The qualifications of those assessing the usability are not specified, beyond the implication that they are competent to conduct a clinical trial for hemodialysis devices.

4. Adjudication Method for the Test Set

Adjudication methods (like 2+1, 3+1) are typically used in studies involving human interpretation (e.g., radiology reads) where there might be disagreement in expert opinions needing a tie-breaker. This is not applicable here as:

• The primary "test set" involves objective performance characteristics (bench testing).
• The clinical usability study likely involved observing successful function and user feedback, not a diagnostic interpretation needing adjudication.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

No. An MRMC study is relevant for evaluating the performance of AI systems or diagnostic tools where multiple human readers interpret cases, often with and without AI assistance, to see if the AI improves human performance. This device is a physical hemodialysis needle set, not an AI or diagnostic tool.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done

Not applicable. This refers to the performance of an AI algorithm on its own. The device is a physical product. Its "standalone" performance is assessed through bench testing (e.g., VND Performance, Mechanical Hemolysis Testing, Needle Penetration Resistance). These tests evaluate the device's inherent functional characteristics independent of human interaction during the critical failure modes.

7. The Type of Ground Truth Used

• Bench Testing: The ground truth is based on objective physical measurements and engineering specifications (e.g., force measurements, leak tests, dimensional analyses) and functional success/failure (e.g., did the VND feature trigger the alarm?).
• Simulated Clinical Usability Study: The ground truth is based on observed device performance during simulated use and the successful delivery of hemodialysis without impedance by the device's novel features. This is akin to outcomes data in a controlled simulated environment.

8. The Sample Size for the Training Set

Not applicable. The device is a physical product and does not involve AI or machine learning models that require a "training set."

9. How the Ground Truth for the Training Set was Established

Not applicable. As there is no training set for an AI model.

In summary, the provided document details the non-clinical and limited clinical testing of a physical medical device (hemodialysis needle set). The acceptance criteria are largely met through rigorous bench testing demonstrating physical and functional robustness, and a small simulated clinical study confirming usability and safety in a controlled environment. AI-specific criteria are not relevant to this type of device.

The provided text is a 510(k) Clearance Letter and 510(k) Summary for the TINGSN FINDERS 2 Color Doppler Diagnostic Ultrasound System. This document describes the device, its intended use, and a comparison to predicate devices to establish substantial equivalence.

Crucially, the document explicitly states under "8. CLINICAL DATA": "No clinical data was included in this submission."

Therefore, based on the provided text, a study that proves the device meets acceptance criteria through clinical data (either standalone or MRMC comparative effectiveness) was not performed, or at least, not included in this submission. The entire submission relies on non-clinical testing and comparison to predicate devices to establish substantial equivalence.

As the request specifically asks for information about a "study that proves the device meets the acceptance criteria" and mentions clinical outcomes, it is impossible to provide the requested details from the given text.

However, I can extract the information related to the non-clinical tests that were performed to verify the device met design specifications and was substantially equivalent, which serve as the basis for clearance in lieu of clinical data.

Here's an interpretation based on the non-clinical data presented:

Device Acceptance Criteria and Performance (Based on Non-Clinical Data)

The TINGSN FINDERS 2 Color Doppler Diagnostic Ultrasound System established its substantial equivalence (SE) based primarily on non-clinical testing and comparison to predicate devices, as no clinical data was included in the submission. The acceptance criteria and "performance" are therefore framed in terms of compliance with relevant standards and demonstration of functional equivalence.

1. Table of Acceptance Criteria and Reported Device Performance (Non-Clinical)

2. Sample Size Used for the Test Set and Data Provenance

• Sample Size: Not explicitly stated for specific non-clinical tests. General statements indicate "non-clinical tests were conducted."
• Data Provenance: The tests were conducted internally by Jiangsu Tingsn Technology Co., Ltd. The document refers to "non-clinical tests (integration and functional) were conducted on the TINGSN FINDERS 2 Color Doppler Diagnostic Ultrasound System during product development."

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

• Not applicable for non-clinical testing. The "ground truth" for non-clinical tests typically refers to engineering specifications, regulatory standards, and established physical principles, not expert interpretations of clinical data.

4. Adjudication Method for the Test Set

• Not applicable for non-clinical testing. Adjudication methods like 2+1 or 3+1 are used for human expert review of clinical cases to establish ground truth or compare diagnostic performance, which was not part of this submission.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

• No MRMC study was done. The submission explicitly states: "No clinical data was included in this submission." MRMC studies inherently involve human readers evaluating clinical cases.

6. Standalone (i.e., algorithm only without human-in-the-loop performance)

• Not applicable as an AI/algorithm-only device. The TINGSN FINDERS 2 is a diagnostic ultrasound system that produces images for human interpretation, not an AI algorithm performing diagnosis independently. The software features listed are for image optimization, measurements, and display, assisting the human user, not replacing them in a "standalone" diagnostic role.

7. The Type of Ground Truth Used

• For non-clinical testing: The "ground truth" was established by performance specifications, engineering requirements, and compliance with the international and national standards listed (e.g., IEC, ISO, NEMA, ASTM, FDA guidance). This includes electrical safety, mechanical robustness, image quality parameters (resolution, penetration, consistency), acoustic output levels, and software functionality validation against design requirements.

8. The Sample Size for the Training Set

• Not applicable. This device is a traditional ultrasound system, not an AI/ML product that undergoes "training."

9. How the Ground Truth for the Training Set Was Established
