This 510(k) clearance letter is for a Disposable Neonatal NIBP Cuff. It does not describe an AI/ML powered medical device, nor does it detail a study involving AI/ML.

Therefore, many of the requested criteria related to AI/ML device validation (e.g., sample size for test/training sets, data provenance, number of experts for ground truth, MRMC study, standalone performance, etc.) are not applicable to this document.

The document primarily focuses on establishing substantial equivalence to a predicate device through non-clinical testing and material biocompatibility.

Here's the information that can be extracted from the provided text, primarily related to the non-clinical testing performed to meet acceptance criteria for a physical medical device:

1. Table of Acceptance Criteria and Reported Device Performance

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

• Sample Size: Not specified in the provided document. The non-clinical testing likely involved a representative sample of each cuff model (U1682S-C51N, U1683S-C51N, U1684S-C51N, U1685S-C51N).
• Data Provenance: The document states "Non-clinical tests were conducted..." but does not specify the country of origin where the testing was performed. Given the manufacturer's location (Shenzhen, China), it's plausible the testing was conducted there or at a certified lab supporting the manufacturer. The testing is described as non-clinical, implying it was laboratory-based product verification and validation, not retrospective or prospective human clinical data collection.

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

This is not applicable. This document describes the clearance of a physical medical device (NIBP cuff) via substantial equivalence, not an AI/ML algorithm. Therefore, there is no mention of "ground truth" derived from expert consensus on medical images or data. The "ground truth" for this device would be the defined specifications and performance requirements established by the relevant ISO standards.

4. Adjudication Method for the Test Set

This is not applicable. Adjudication methods like 2+1 or 3+1 are typically used in clinical trial settings, especially for AI/ML performance evaluation where multiple human readers might disagree on findings. For non-clinical device testing like this, adherence to predefined test protocols and specifications is the primary method of evaluation.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No, a MRMC comparative effectiveness study was not done. This type of study is relevant for evaluating the impact of AI assistance on human reader performance, which is not applicable to a non-AI medical device like a blood pressure cuff.

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

No, a standalone performance evaluation of an algorithm was not done. This is not an AI/ML device.

7. The Type of Ground Truth Used

The "ground truth" for this device's performance is established by compliance with recognized consensus standards (ISO 81060-1, ISO 80601-2-30, and ISO 10993 series for biocompatibility). The device's performance metrics are evaluated against the specific requirements and test methods outlined in these standards.

8. The Sample Size for the Training Set

This is not applicable. There is no training set mentioned 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 mentioned as this is not an AI/ML device.

Ask a specific question about this device

The Radius VSM and accessories are intended to be used as both a wearable multi-parameter patient monitor and an accessory to a multi-parameter patient monitor that is intended for multi-parameter physiological patient monitoring in hospital and healthcare facilities.

The Radius VSM and accessories are indicated for the monitoring of hemodynamic (including ECG, arrhythmia detection, non-invasive blood pressure, SpO2, Pulse Rate, PVi, heart rate, and temperature), and respiratory (e.g., impedance, acoustic, and pleth-based respiration rate) physiological parameters along with the orientation and activity of adults.

The Radius VSM and accessories are indicated for the non-invasive continuous monitoring of functional oxygen saturation of arterial hemoglobin (SpO2) and Pulse Rate (PR) of well or poorly perfused adults during both no motion and motion conditions.

The Radius VSM and accessories are indicated for continuous monitoring of skin temperature of adults.

The Radius VSM and accessories are indicated for monitoring of the orientation and activity of patients including those susceptible to pressure ulcers.

The Radius VSM and accessories are indicated for the continuous non-invasive monitoring of PVi as a measure of relative variability of the photoplethysmograph (pleth) of adults during no motion conditions. PVi may be used as a noninvasive dynamic indicator of fluid responsiveness in select populations of mechanically ventilated adult patients. Accuracy of PVi in predicting fluid responsiveness is variable and influenced by numerous patient, procedure and device related factors. PVi measures the variation in the plethysmography amplitude but does not provide measurements of stroke volume or cardiac output. Fluid management decisions should be based on a complete assessment of the patient's condition and should not be based solely on PVi.

Devices with Masimo technology are only indicated for use with Masimo accessories.

Radius VSM Accessories:

Radius VSM ECG Electrodes are disposable, single-patient use ECG electrodes intended to acquire ECG signals from the surface of the body. They are indicated for use on adults for up to 3 days of skin surface contact.

Radius VSM Blood Pressure Cuffs are accessories intended to be used with a noninvasive blood pressure measurement system to measure blood pressure. They are indicated for use on adults during no motion conditions.

The Radius VSM and accessories are an FDA cleared (K223498), wearable, battery-operated, multi-modular patient monitoring platform that allows for the ability to scale and tailor the use of different monitoring technologies based upon the hospital and clinician's assessment of what technologies are appropriate.

As part of this submission, a MAP feature is being added to the Radius VSM. The feature is a software feature that uses the previously cleared systolic and diastolic measurement capabilities to automate the calculation of MAP using the following formula: MAP = 1/3* Systolic + 2/3*Diastolic.

The MAP is calculated by the Radius VSM NIBP Module and displayed on the Radius VSM Wearable Monitor. There were no other features added as part of this submission.

The provided 510(k) clearance letter and summary discuss the addition of a Mean Arterial Pressure (MAP) feature to the previously cleared Radius VSM and Accessories device. The primary focus of the performance data section is on validating this new MAP feature.

Here's an analysis of the acceptance criteria and the study proving the device meets them, based on the provided document:

Acceptance Criteria and Reported Device Performance

The document states that the acceptance criterion for Blood Pressure (including MAP) is:

"Meets ISO 81060-2 (Mean difference of ≤5 mmHg with a standard deviation of ≤8 mmHg)"

The document directly states that the results of the clinical testing supported the clinical performance of the MAP in accordance with ISO 81060-2. While specific numerical results (e.g., the exact mean difference and standard deviation achieved) are not explicitly provided in the summary table, the clearance implies that these metrics fell within the specified ISO 81060-2 limits for the MAP feature.

Table 1: Acceptance Criteria and Reported Device Performance for MAP Feature (as inferred from the document)

Study Details for MAP Feature Validation

1. Sample Size Used for the Test Set and Data Provenance:

   • Sample Size: The document does not explicitly state the numerical sample size (number of subjects/patients) used for the clinical test set. It only mentions "clinical study data."
   • Data Provenance: The document does not specify the country of origin. It indicates it was a "clinical study" and implies it was prospective ("clinical testing is provided to support its performance" for the added feature).

2. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of those Experts:

   • Not applicable as the ground truth was established by an objective reference device, not human experts.

3. Adjudication Method for the Test Set:

   • Not applicable, as the method for ground truth establishment was comparison to a reference device.

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

   • No, an MRMC study was not done. The study was a comparison of the device's calculated MAP to invasively measured MAP from a reference device. This is a technical performance validation, not a study assessing human reader improvement with AI assistance.

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

   • Yes, this was a standalone performance study. The Radius VSM automatically calculates the MAP based on the NIBP measurements (Systolic and Diastolic Pressure). The clinical testing validated the accuracy of this calculation against a reference standard, without human intervention in the MAP calculation or interpretation for the test itself.

6. The Type of Ground Truth Used:

   • Reference Ground Truth: Invasively measured MAP values from a 510(k) cleared reference device (K171801). This reference device is identified as "IntelliVue Multi-Measurement Module X3." This constitutes a device-based reference standard or instrument-based ground truth.

7. The Sample Size for the Training Set:

   • The document does not provide information about a training set since the MAP feature appears to be a direct calculation using a standard formula (MAP = 1/3* Systolic + 2/3*Diastolic) rather than a machine learning model that requires a training phase. While the device as a whole (Radius VSM) likely had training and validation phases for its other parameters, the specific "addition of a Mean Arterial Pressure (MAP) feature" is described as a software feature that "automates the calculation" using a known formula. Therefore, a separate training set for this specific MAP feature is unlikely to have been required or used in the conventional machine learning sense.

8. How the Ground Truth for the Training Set was Established:

   • As inferred above, a specific training set and ground truth establishment for this isolated MAP calculation feature are not described, given its nature as a direct formulaic calculation.

Summary of Key Information:

The core of this submission revolves around adding a simple, formula-based calculation for MAP. The primary study presented is a clinical validation confirming that the device's computed MAP aligns with a known industry standard (ISO 81060-2) when compared against an invasive reference device. This is a technical performance validation rather than a complex AI-driven diagnostic study.

Therefore, the document does not contain the information required to describe the acceptance criteria and the study that proves an AI/ML device meets those criteria.

Specifically, the document does not provide:

• A table of acceptance criteria and reported device performance: The document lists standards the device complies with (IEC 80601-2-30, ISO 81060-1, ISO 10993-5, ISO 10993-10), but these are general safety and performance standards for a mechanical device, not AI/ML acceptance criteria like sensitivity, specificity, or AUC. No specific performance metrics are reported against quantitative acceptance criteria.
• Sample size and data provenance for a test set: No mention of a test set, data provenance, or sample size for evaluating AI/ML algorithm performance.
• Number and qualification of experts for ground truth: Not applicable, as this is not an AI/ML device requiring expert-established ground truth.
• Adjudication method: Not applicable.
• MRMC comparative effectiveness study: Not applicable.
• Standalone (algorithm only) performance: Not applicable.
• Type of ground truth used: Not applicable.
• Sample size for the training set: Not applicable.
• How ground truth for the training set was established: Not applicable.

The document states:

• "6. Non-Clinical Test Conclusion" and "6.1 Non clinical tests were conducted to verify that the proposed device met all design specifications as was Substantially Equivalent (SE) to the predicate device. The test results demonstrated that the proposed device complies with the following standards: IEC 80601-2-30: 2018..., ISO 81060-1:2007..., ISO 10993-5: 2009..., ISO 10993-10: 2010..."
• "6.2 Human Factors / Usability Testing Usability testing is not required per the risk profile of this product."
• "7. Clinical Test Conclusion No clinical study is included in this submission."

This unambiguously indicates that the submission is for a physical medical device (a blood pressure cuff), assessed through non-clinical bench testing for compliance with manufacturing and biocompatibility standards, and not an AI/ML driven diagnostic or assistive device that would require the specified performance evaluations.

The provided text is a 510(k) summary for a Blood Pressure Cuff. It focuses on demonstrating substantial equivalence to predicate devices rather than proving the device meets specific acceptance criteria through a clinical study with detailed performance metrics. The information about a study proving device performance is limited.

Here's an analysis based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance:

The document primarily refers to meeting ISO standards and does not present a table of specific acceptance criteria (e.g., specific accuracy ranges for blood pressure measurements) versus reported device performance in a clinical setting. It states that the device was "tested according to ISO 81060-1 Non-invasive sphygmomanometers - Part 1: Requirements and test methods for non-automated measurement type". However, it does not provide the results of this testing in a quantifiable form or against specific, pre-defined acceptance criteria.

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

The document states, "The subject and predicate devices are exactly the same. Since the blood pressure cuffs are identical, no further clinical testing is necessary." This implies that no separate test set with human subjects was used for this 510(k) submission to evaluate the performance of the device in terms of blood pressure measurement accuracy. The data provenance is assumed to be from the predicate device's testing, but details are not provided here.

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

Since no separate clinical performance testing was conducted for this submission, no experts were used to establish ground truth from newly collected data for this specific device.

4. Adjudication Method for the Test Set:

Not applicable, as no dedicated clinical performance test set was used for this submission.

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

Not applicable, as this is a blood pressure cuff and not an AI-powered diagnostic imaging device. The document does not describe any human reader involvement or AI assistance.

6. Standalone Performance Study:

A standalone performance study focused on technical compliance with ISO 81060-1 was mentioned ("The subject device has been tested according to ISO 81060-1 Non-invasive sphygmomanometers - Part 1: Requirements and test methods for non-automated measurement type"). However, the results of this testing, which would quantify its performance against the ISO standard's requirements, are not provided in this summary. The summary only attests that the device "met the requirements."

7. Type of Ground Truth Used:

For the "performance data" mentioned, the ground truth would be the reference measurements and methods defined within the ISO 81060-1 standard for non-invasive sphygmomanometers. For the biocompatibility testing, the ground truth would be the established scientific methods and criteria for evaluating cytotoxicity, sensitization, and irritation.

8. Sample Size for the Training Set:

Not applicable, as this is a medical device (blood pressure cuff) and not an AI/ML algorithm that requires a training set.

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

Not applicable.

Summary of Acceptance Criteria and Study (based on available information):

Study Details:

The proposed device includes disposable blood pressure cuff and reusable blood pressure cuff. Both disposable and reusable blood pressure cuff have the same structure, which contains Cuff with bladder and single-tube Air Hose.

This document is a 510(k) Premarket Notification from the FDA regarding a non-invasive blood pressure (NIBP) cuff. It focuses on demonstrating substantial equivalence to a predicate device rather than providing a detailed study report of the device's accuracy or efficacy as one might find for a more complex AI-driven medical device.

Therefore, the requested information, particularly concerning "acceptance criteria" and "study that proves the device meets the acceptance criteria" in the context of an AI/algorithm-driven device (like an effect size of human readers improving with AI, or standalone algorithm performance), is largely not applicable to this document. This document primarily describes the physical characteristics, intended use, and manufacturing standards of a blood pressure cuff.

However, I can extract the relevant information where available, focusing on performance data related to blood pressure cuffs.

Here's an analysis based on the provided text:

Key Takeaway: This 510(k) submission primarily relies on physical and material testing and comparison to a predicate device to demonstrate substantial equivalence, not a clinical study proving its performance against specific physiological accuracy criteria in humans, nor an AI-driven system's performance.

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

The document doesn't present a table of acceptance criteria and corresponding reported device performance in the same way one would for an AI model's diagnostic accuracy. Instead, it refers to compliance with established standards for blood pressure cuffs.

Ask a specific question about this device

The aneroid sphygmomanometer is intended to be used by medical professionals or in the home for the measurement of systolic and diastolic pressure on children or adults. The device is intended to a patient and manually inflated along with a manual method for detecting Korotkoff sounds.

The product is a manual non-invasive aneroid sphygmomanometer which respectively uses an inflation cuff wrapped around the upper arm. The cuff is inflated and deflated by a manual inflation bulb. Besides a manometer (Aneroid gauge), the accessories of MODEL Ks-1222,Ks-1621,Ks-3201,Ks-2203 also includes one selected cuff, one inflation bulb, instruction manual and a vinyl bag. It is conjunction with Stethoscope when use.

The provided document is a 510(k) summary for an Aneroid Sphygmomanometer. It details the device's characteristics and its comparison to a predicate device to establish substantial equivalence. However, this document does not describe a study involving an AI-powered device or a multi-reader multi-case (MRMC) comparative effectiveness study.

The device in question, an "Aneroid Sphygmomanometer," is a manual, non-automated blood pressure meter. The performance testing cited is against ISO 81060-1:2007 "Non-invasive sphygmomanometersPart 1: Requirements and test methods for non-automated measurement type." This standard governs the accuracy of manual blood pressure devices, not AI performance.

Therefore, many of the requested details, such as acceptance criteria for AI performance, sample sizes for test/training sets for AI, ground truth establishment for AI, expert involvement for AI, MRMC studies, and standalone AI performance, are not applicable to this submission.

The document focuses on demonstrating that the new manual device performs similarly to a legally marketed predicate manual device and meets relevant performance and biocompatibility standards for non-automated devices.

However, I can extract the general "acceptance criteria" for the accuracy of the blood pressure measurement as stated in the comparison table and the performance test standard:

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

• Sample Size for performance testing: The document states "full performance testing representing the current devices currently marketed" and mentions compliance with ISO 81060-1. While the specific number of subjects/measurements is not detailed in this summary, ISO 81060-1 typically requires clinical validation with a certain number of subjects (e.g., at least 85 subjects for blood pressure accuracy evaluation). The document does not specify data provenance (country, retrospective/prospective).
• Data Provenance: Not explicitly stated.

• Not applicable for AI-driven performance. For a manual blood pressure device assessed against ISO 81060-1, the "ground truth" for blood pressure typically comes from a reference measurement method (e.g., intra-arterial measurement or a highly accurate clinical standard measurement performed by trained personnel). The document does not specify the number or qualifications of these individuals involved in the ground truth establishment for clinical validation, as it's a standard process dictated by the ISO standard.

4. Adjudication method for the test set:

• Not applicable for AI-driven performance. For a manual blood pressure device, adjudication would not be in the typical sense of expert review of AI outputs.

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, an MRMC study was not done. This is a manual, non-AI device.

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

• Not applicable. This is a manual device; there is no algorithm in the sense of AI. The performance testing is for the physical device itself.

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

• For blood pressure measurement accuracy (referenced by ISO 81060-1), the ground truth is typically established by simultaneous measurements using a highly accurate reference method (e.g., intra-arterial pressure or a validated mercury sphygmomanometer measurement by trained observers). This is a technical ground truth related to physical measurement.

8. The sample size for the training set:

• Not applicable. This is a non-AI device; there is no "training set."

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

• Not applicable. This is a non-AI device.

In summary, the provided FDA 510(k) summary is for a traditional, non-automated medical device (Aneroid Sphygmomanometer). Therefore, it does not contain information related to AI-specific study designs, acceptance criteria, or performance metrics. The "study" proving the device meets acceptance criteria refers to non-clinical performance testing against established international standards for manual blood pressure devices and biocompatibility.

Radius VSM:

The Radius VSM and accessories are intended to be used as both a wearable multi-parameter patient monitor and an accessory to a multi-parameter patient monitor that is intended for multi-parameter physiological patient monitoring in hospital and healthcare facilities.

The Radius VSM and accessories are indicated for the monitoring of hemodynamic (including ECG, arrhythmia detection, non-invasive blood pressure, SpO2, Pulse Rate, PVi, heart rate, and temperature), and respiratory (e.g., impedance, acoustic, and pleth-based respiration rate) physiological parameters along with the orientation and activity of adults.

The Radius VSM and accessories are indicated for the non-invasive continuous monitoring of functional oxygen saturation of arterial hemoglobin (SpO2) and Pulse Rate (PR) of well or poorly perfused adults during both no motion and motion conditions.

The Radius VSM and accessories are indicated for continuous monitoring of skin temperature of adults.

The Radius VSM and accessories are indicated for monitoring of the orientation and activity of patients including those susceptible to pressure ulcers.

The Radius VSM and accessories are indicated for the continuous non-invasive monitoring of PVI as a measure of relative variability of the photoplethysmograph (pleth) of adults during no motion conditions. PVi may be used as a noninvasive dynamic indicator of fluid responsiveness in select populations of mechanically ventilated adult patients. Accuracy of PVi in predicting fluid responsiveness is variable and influenced by numerous patient, procedure and device related factors. PV i measures the variation in the plethysmography amplitude but does not provide measurements of stroke volume or cardiac output. Fluid management decisions should be based on a complete assessment of the patient's condition and should not be based solely on PVi.

Devices with Masimo technology are only indicated for use with Masimo accessories.

Radius VSM Accessories:

Radius VSM ECG Electrodes are disposable, single-patient ECG electrodes intended to acquire ECG signals from the surface of the body. They are indicated for use on adults for up to 3 days of skin surface contact.

Ask a specific question about this device

The blood pressure cuff is an accessory used in con-invasive blood pressure measurement systems. It is non-sterile, single-patient use. It is available in pediatric and adult sizes. The cuff is not designed, sold or intended for use except as indicated.

ONE-CUF blood pressure cuffs are accessories used in conjunction with noninvasive blood pressure (NIBP) measurement systems to obtain a blood pressure measurement. Blood pressure cuffs are non-sterile and single-patient use and may not be reprocessed for use on additional patients. They are available in pediatric and adult sizes. The devices are not designed, sold or intended for use except as indicated. Blood pressure cuffs do not include serviceable parts or components. Non-Invasive Blood Pressure Cuffs incorporate an inflatable non-distensible bladder, sized to encircle a patient's limb. The cuff includes one or two flanges for attaching flexible tubing. This allows air to flow in and out of the cuff bladder for inflation and deflation. Inflation allows for occlusion of an artery to facilitate the measurement of automated noninvasive blood pressure (NIBP). The cuff tubes are terminated with connectors that allow for attachment to a blood pressure hose. This cuff will be offered with two different connection systems, bayonet and DINACLICK.

The information provided describes the ONE-CUF blood pressure cuff and its path to substantial equivalence, primarily based on non-clinical testing and comparison to a predicate device. It explicitly states that no clinical or animal studies were required to support substantial equivalence. Therefore, there is no study described that proves the device meets specific acceptance criteria related to a model's performance in a diagnostic or predictive context (e.g., accuracy, sensitivity, specificity for an AI algorithm).

The "acceptance criteria" referred to in this document are primarily related to product performance specifications and compliance with voluntary standards for a mechanical medical device, rather than the performance metrics of an AI model.

Summary of the Study that Proves the Device Meets Acceptance Criteria:

The “study” proving the ONE-CUF meets its acceptance criteria is a compilation of non-clinical performance testing and biocompatibility testing, along with compliance with relevant voluntary standards. The documentation states:

• Non-Clinical Testing: This included evaluations for Environmental Conditioning, Leak, Pressure Capacity, Mechanical Strength, Tensile Testing, and other performance aspects. While specific results are not detailed in the summary, these tests were submitted to support substantial equivalence.
• Biocompatibility Testing: This was performed in accordance with ISO 10993-1:2018 ("Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process") and included Chemical Characterization, Cytotoxicity, Sensitization, and Irritation/Intracutaneous Reactivity.
• Compliance with Voluntary Standards: The device was designed and tested for compliance with IEC 80601-2-30:2018 (for automated noninvasive sphygmomanometers) and ISO 81060-1:2007 (for non-automated sphygmomanometer test methods).
• Human Factors Validation: Summative usability testing was performed.

The conclusion is that based on these non-clinical performance data, biocompatibility results, and compliance with standards, the device is considered substantially equivalent to a legally marketed predicate device (SOFT-CUF K120125). No clinical or animal studies were required or performed to support this determination.
