The device is intended to be used by medical professionals or in the home for the measurement of systolic and diastolic pressure. The device is intended to be manually attached to a patient and manually inflated along with a manual method for detecting Korotkoff sounds. This product can measure the blood pressure of people aged 3 years and above.
Aneroid sphygmomanometer Model QL-20, QL-201/ Aneroid sphygmomanometer with stethoscope, Model QL-50 are 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 include cuff, inflation bulb, instruction manual and carrying case. Model OL-50 also includes a stethoscope. It is conjunction with stethoscope when use.
The provided text describes a 510(k) premarket notification for an aneroid sphygmomanometer. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving novel clinical effectiveness or algorithm performance.
Therefore, the requested information (acceptance criteria for an AI/device algorithm, MRMC study, standalone performance, training/test set details, expert ground truth establishment, etc.) is largely not applicable to this specific document as it pertains to a traditional medical device (manual blood pressure cuff) and not an AI/ML-driven diagnostic or assistive device.
However, I can extract and present the performance criteria that are relevant to this device type based on the provided document:
Acceptance Criteria and Device Performance (for an Aneroid Sphygmomanometer)
Since this is a traditional medical device (aneroid sphygmomanometer) and not an AI/ML-driven device, the acceptance criteria and performance evaluation focus on its physical and functional accuracy for blood pressure measurement, as well as biocompatibility, rather than AI performance metrics like sensitivity, specificity, or AUC.
1. Table of Acceptance Criteria and Reported Device Performance
Criterion | Acceptance Criteria (Standard Reference) | Reported Device Performance (Subject Device) |
---|---|---|
Accuracy (Pressure) | ± 3 mmHg of reading (ISO 81060-1) | ± 3 mmHg of reading |
Biocompatibility | Complies with ISO 10993-1, ISO 10993-5, ISO 10993-10 | Biocompatible as required by ISO 10993-1, ISO 10993-5, ISO 10993-10 |
Environmental Compatibility | 50°F to 104°F (10°C to 40°C) and 15%~85% RH humidity | Can be used from 50°F to 104°F (10°C to 40°C) and 15%~85% RH humidity |
Monitor Scale | From 0 to 300mmHg with a minimum interval of 2mmHg | From 0 to 300mmHg with a minimum interval of 2mmHg |
Inflation Method | Manual by inflation bulb | Manual by inflation bulb |
Deflation Method | Manual deflation via valve | Manual deflation via valve |
Display Type | Aneroid Manometer | Aneroid Manometer |
2. Sample size used for the test set and the data provenance:
- The document does not specify a patient sample size for testing the aneroid sphygmomanometer itself. The testing performed was "Non-clinical testing" conducted to verify compliance with standards like ISO 81060-1. This standard typically involves technical accuracy testing, often on a test bench or with simulated pressures, and potentially with a limited number of human subjects for specific validation aspects depending on the exact test protocol followed.
- The data provenance is not explicitly stated as it would be for a clinical study. The device is manufactured by Zhejiang LuDe Technology Development Co., Ltd. in China. The testing would have been conducted by the manufacturer or a designated testing facility to meet regulatory requirements.
- The testing was described as "Non-clinical testing," implying it was not a large-scale prospective clinical trial with a defined patient population.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This is not applicable as the device is a manual blood pressure monitor. "Ground truth" for blood pressure measurement (the actual pressure) is established through standardized calibration and reference measurement methods, not through expert consensus on images or interpretations.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not applicable. Adjudication methods are typically used in studies where human readers interpret data (e.g., medical images) and their interpretations need to be reconciled to form a ground truth. For a physical measurement device like a sphygmomanometer, accuracy is determined by comparison to a calibrated reference standard.
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 type of study is specifically designed for AI-assisted diagnostic tools and involves human readers interpreting cases with and without AI assistance. This document is for a traditional, manual blood pressure monitor without AI capabilities.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not applicable. This device does not have a standalone algorithm in the sense of an AI interpreting medical data. Its "performance" refers to its physical accuracy in measuring blood pressure.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- The ground truth for the "Accuracy" criterion would be calibrated reference pressures, produced by a precisely controlled pressure source. This is standard for testing blood pressure measuring devices against the ISO 81060-1 standard.
8. The sample size for the training set:
- Not applicable. This device is a hardware product, not an AI/ML model that requires a training set.
9. How the ground truth for the training set was established:
- Not applicable. As above, no training set for an AI/ML model is involved.

The provided document is a 510(k) premarket notification for an Aneroid Sphygmomanometer. This type of regulatory submission primarily focuses on demonstrating substantial equivalence to a predicate device rather than providing detailed study results of the device meeting specific acceptance criteria in the same way, for example, a novel AI algorithm might. Therefore, some of the requested information, particularly around clinical studies, ground truth establishment, and expert consensus, is not directly applicable or available in this document.
However, I can extract information related to the device's technical specifications and the standards it aims to meet for substantial equivalence.
Here's an analysis based on the provided text, addressing the points where information is available:
1. Table of Acceptance Criteria and Reported Device Performance
For this medical device, the "acceptance criteria" are primarily defined by the performance requirements of the ISO 81060-1 standard for non-invasive sphygmomanometers, and the "reported device performance" indicates compliance with these standards.

Performance Standard | Compatible with ISO 81060-1 | Compatible as requirement of ISO 81060-1 |
2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state a "sample size" for a test set in the context of a clinical study or a dataset for an algorithm. This submission references "Non-clinical testing included biocompatibility and bench testing." It does not provide details on the number of units tested or the specific methodology for these bench tests, beyond stating that they were included in the ISO 10993 and ISO 81060-1 standards.
The data provenance is from non-clinical testing conducted to demonstrate compliance with standards like ISO 10993 and ISO 81060-1. The document does not specify country of origin for this testing data, but the manufacturer is HONSUN (NANTONG) Co., Ltd in China. The testing would be considered bench testing rather than retrospective or prospective clinical data.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
Not applicable. For this type of device (a mechanical aneroid sphygmomanometer), ground truth for performance claims is established through a calibrated reference standard (e.g., a manometer calibrated to a known pressure standard) during bench testing, as specified by standards like ISO 81060-1. There would be no "experts" establishing a ground truth in the context of subjective interpretation like with medical imaging.
4. Adjudication Method for the Test Set
Not applicable. Adjudication methods (like 2+1, 3+1) are typically used for establishing ground truth in studies involving human interpretation of data, often in clinical trials or studies for AI algorithms. For a mechanical device's performance testing (like pressure accuracy), the measurement is objective against a standard, not subject to adjudication.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of Human Readers Improving with AI vs. Without AI Assistance
No. This device is an aneroid sphygmomanometer, which is a manual non-invasive blood pressure measurement device. It does not incorporate artificial intelligence, nor does it involve "readers" in the context of image interpretation or diagnostic decision-making. Therefore, an MRMC study or an assessment of human reader improvement with AI assistance is not relevant or applicable.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
No. This device is a mechanical instrument and does not contain an algorithm. "Standalone performance" in this context would refer to the device's accuracy and performance specifications as outlined in the table above, which are assessed through bench testing against established standards.
7. The Type of Ground Truth Used
For this device, the "ground truth" for pressure accuracy is a calibrated pressure standard as mandated by the ISO 81060-1 standard for non-invasive sphygmomanometers. This standard defines the methods for verifying the accuracy of the device against a known, precise pressure.
8. The Sample Size for the Training Set
Not applicable. This device is a mechanical medical instrument. It does not utilize an algorithm, machine learning, or artificial intelligence; therefore, there is no "training set" of data.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this mechanical device.

Instruction booklet and record 5. Carrying case.
The provided text describes a 510(k) summary for an Aneroid Sphygmomanometer with Stethoscope, Model LD-100. This document primarily focuses on demonstrating substantial equivalence to a predicate device and adherence to recognized standards for non-automated sphygmomanometers.
Based on the provided text, the following information can be extracted:
-
A table of acceptance criteria and the reported device performance:
Acceptance Criteria Reported Device Performance Conformance to AAMI/ANSI SP10:2002/A2:2006 Standard for Non-automated Sphygmomanometers AAMI/ANSI SP10:2002/A2:2006 "Standard for Manual, Automated, and Semi-automated Sphygmomanometers" was used. The conclusion states "conformance to AAMI/ANSI SP10:2002/A2:2006". Non-clinical mechanical testing Non-clinical mechanical testing was performed. -
Sample size used for the test set and the data provenance:
- The document does not specify sample sizes for any test sets.
- The document does not specify data provenance (e.g., country of origin, retrospective or prospective) for clinical data. The studies mentioned are referred to simply as "studies" and "non-clinical mechanical testing." It's possible the AAMI/ANSI standard itself outlines testing methodologies that were followed, but the specific details of participants/data provenance are not in this summary.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This information is not provided in the document. The studies mentioned are non-clinical and based on a standard for manual/automated sphygmomanometers, which typically involves technical performance metrics rather than expert interpretation of results.
-
Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- This information is not provided in the document. Given the nature of a non-automated sphygmomanometer and the focus on technical standards, an adjudication method for a test set is unlikely to be relevant in the same way it would be for an AI diagnostic device.
-
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 comparative effectiveness study was not conducted. This device is a mechanical blood pressure monitor, not an AI diagnostic device that assists human readers.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- This device is a "non-automated, mechanical blood pressure monitor." It is not an algorithm. Therefore, a standalone algorithm performance study is not applicable and was not done. The device's performance is inherently "standalone" in the sense that its measurements are direct, although it requires a human operator for proper use and interpretation of Korotkoff sounds via the stethoscope.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- The document implies the ground truth for performance is established by the AAMI/ANSI SP10:2002/A2:2006 standard. This standard outlines performance requirements and test methods for accuracy and other characteristics of sphygmomanometers. The ground truth would therefore be derived from reference devices or established measurement protocols defined in the standard.
-
The sample size for the training set:
- The device is a mechanical blood pressure monitor, not an AI/machine learning algorithm. Therefore, there is no training set in the context of machine learning.
-
How the ground truth for the training set was established:
- As there is no training set (the device is mechanical), this question is not applicable.
