This Blood Pressure Monitor is a digital monitor intended for use in measuring blood pressure and pulse rate with arm circumference ranging from 22cm to 32cm (about 8¾ -12½´) or 22cm to 42cm (about 834"-161/2"). It is intended for adult indoor use only.
Blood Pressure Monitor BBZ32-AA01 is designed to measure systolic pressure, diastolic pressure and pulse rate of adult by a non-invasive technique, with an inflatable cuff wrapped around the upper arm. The method to define systolic and diastolic pressure is similar to auscultatory method, though it uses an electronic pressure sensor rather than a stethoscope and mercury manometer. The sensor converts tiny alternations of cuff pressure into electrical signals. Based on analysis of these signals, the systolic and diastolic blood pressure is defined, and the pulse rate is calculated. This is an extensively used technique applied in blood pressure monitors, also known as "oscillometric method". The main components of the Blood Pressure Monitor include main unit and cuff. For the outer housing of the main unit, it's made of HIPS material. As for accompanying cuffs, two types of cuffs have been clinically validated to be matched with the device, suitable for adults with arm circumference from 22cm~42cm. The cuff is consisted of fabric and an inflatable bladder inside. For critical electronic components, there is PCB, thermistor, pressure pump, motor, release valve and pressure sensor. The device also enjoys a function of detecting irregular pulse rate. When measurements were performed, the monitor will record all pulse intervals and calculate the average. If two or more pulse intervals were recorded, and the difference between each interval and the average is larger than ±25% of the average; or if four or more pulse intervals were recorded, and the difference between each interval and the average is larger than ±15% of the average, the irregular pulse symbol will be displayed along with measurement results. An embedded Bluetooth wireless connection module in the device allows it to connect with matching receiving ends. When a measurement is done, the results will be displayed on LCD, and the measured data will be transferred to the APP via Bluetooth.
The Guangdong Transtek Medical Electronics Co., Ltd. Blood Pressure Monitor (BBZ32-AA01) underwent a clinical study to demonstrate its performance against established acceptance criteria.
1. Table of Acceptance Criteria and Reported Device Performance
The device's performance was evaluated against the criteria outlined in ISO 81060-2:2018/Amd.1:2020 for non-invasive sphygmomanometers. The document does not explicitly present these as a table of "acceptance criteria," but rather as two validation criteria (Criterion 1 and Criterion 2) that the device must fulfill. The reported device performance is indicated as having fulfilled both these criteria.
| Criterion | Acceptance Criteria (Implicit from ISO 81060-2:2018/Amd.1:2020) | Reported Device Performance (Mean Difference +/- Standard Deviation) |
|---|---|---|
| Impulse Test (e.g., Blood Pressure Accuracy) | (Criterion 1) Mean difference and standard deviation of differences between reference blood pressure and device readings | Systolic BP: 0.17 ± 2.57 mmHg; Diastolic BP: 0.79 ± 2.09 mmHg |
| Impulse Test (e.g., Blood Pressure Accuracy) | (Criterion 2) Mean difference and standard deviation of differences between reference blood pressure and device readings | Systolic BP: 0.17 ± 1.99 mmHg; Diastolic BP: 0.79 ± 1.68 mmHg |
Note: The exact numerical thresholds for acceptance for Criterion 1 and 2 from ISO 81060-2:2018/Amd.1:2020 are not explicitly stated in this document but are implied to have been met by the reported performance.
2. Sample Size and Data Provenance
- Test Set Sample Size: 86 qualified subjects.
- Data Provenance: The document does not explicitly state the country of origin but mentions the manufacturer is "Guangdong Transtek Medical Electronics Co., Ltd." in China. It is a prospective clinical study, as indicated by "The clinical study was performed on the device..."
3. Number of Experts and Qualifications
The document does not provide information on the number of experts used to establish the ground truth or their specific qualifications (e.g., radiologist with 10 years of experience). It only refers to "reference BPs" for comparison.
4. Adjudication Method
The document does not specify an adjudication method like 2+1 or 3+1 for establishing ground truth. The "reference BPs" suggest a gold standard measurement was used, but the process for ensuring its accuracy is not detailed.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No multi-reader multi-case (MRMC) comparative effectiveness study was done to assess human readers' improvement with or without AI assistance. This device is a standalone blood pressure monitor, not an AI-assisted diagnostic tool.
6. Standalone Performance
Yes, a standalone performance study was done. The clinical study described evaluates the algorithmic (device) performance in measuring blood pressure and pulse rate without human-in-the-loop assistance for interpretation or adjudication of results.
7. Type of Ground Truth Used
The ground truth used was "reference BPs." This implies that the device readings were compared against highly accurate and established blood pressure measurements, likely obtained by a validated manual method (e.g., auscultatory method by trained professionals) or another highly accurate reference device.
8. Sample Size for the Training Set
The document does not mention a training set sample size. This suggests the blood pressure monitor is likely based on an established oscillometric algorithm rather than a machine learning model that requires a dedicated training set.
9. How the Ground Truth for the Training Set Was Established
Since no training set is mentioned (implying a rule-based or conventional algorithm rather than a machine learning model), the method for establishing ground truth for a training set is not applicable or detailed in this document.

6. Comparison to Predicate Device
{6}------------------------------------------------
{7}------------------------------------------------
Justification for difference:
Note 1:
Although there are some differences between the "Intended Use / Indication for Use" of the subject device and predicate device, it is only expressed differently, and the general meaning is the same, and they both use in measuring blood pressure and pulse rate. Thus, the difference here does not raise any issues concerning safety and effectiveness.
Note 2:
Although there are some differences between the "Arm circumference" and "Pulse Rate Measurement" of the subject device and the predicate device, both the subject device and predicate device can be applied to 22-32cm and 22-42cm arm circumference, the pulse rate range of the subject device is similar to that of the predicate device, and the subject device has also been validated according to IEC 80601-2-30 and ISO 81060-2. As demonstrated in relevant test reports, the difference here does not raise any issues concerning safety and effectiveness.
Note 3:
Although there are some differences between the "Power Supply", "Memory", "Operation Environment", "Storage and transportation Environment" and "Wireless" of the subject device and the predicate device, both the subject device and predicate device comply with the requirement of standard AAMI ANSI ES 60601-1, IEC 60601-1-11, IEC 60601-1-2 and IEC 80601-2-30, and the subject device also complies with the guidance "Content of Premarket Submissions for Device Software Functions". As demonstrated in relevant test reports, the difference here does not raise any issues concerning safety and effectiveness.
Conclusion:
Based on the comparison and analysis in this submission, it can be concluded that: the subject device is substantially equivalent to the predicate device and reference device regarding safety and effectiveness.
