There is no mention of AI or ML in the device description, intended use, or performance studies. The irregular pulse detection is based on simple interval comparisons, not complex pattern recognition typically associated with AI/ML.
No
Explanation: The device is a Blood Pressure Monitor, which measures blood pressure and pulse rate. Its intended use and device description indicate it is for diagnostic or monitoring purposes, not for treating a condition.
Yes
The device measures blood pressure and pulse rate, and it specifically mentions "detecting irregular pulse rate" and displaying an "irregular pulse symbol" when certain conditions are met, which indicates it provides information to assist in the diagnosis of an irregular pulse.
No
The device description explicitly states that the main components include a main unit and cuff, which are hardware components. It also lists critical electronic components like a pressure pump, sensor, and valve. While it has a Bluetooth module for data transfer to an app, the core blood pressure measurement functionality relies on physical hardware.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: This device is a Blood Pressure Monitor. It measures blood pressure and pulse rate by applying a cuff to the upper arm and using an oscillometric method. This is a non-invasive measurement performed directly on the body, not on a sample taken from the body.
- Intended Use: The intended use clearly states it's for "measuring blood pressure and pulse rate with arm circumference ranging from..." This describes a physiological measurement, not a diagnostic test on a biological sample.
- Device Description: The description details the components and how the device measures pressure and pulse rate using a cuff and sensor. There is no mention of analyzing biological samples.
Therefore, this Blood Pressure Monitor falls under the category of a non-invasive medical device used for physiological monitoring, not an In Vitro Diagnostic device.

Device Description
Blood Pressure Monitor TMB-2266 is designed to measure systolic pressure, diastolic pressure and pulse rate of population at or over 3 years old 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, five types of cuffs have been clinically validated to be matched with the device, suitable for population aged at or over three and with arm circumference from 16cm~45cm. The cuff is consisted of fabric and an inflatable bladder inside. For critical electronic components, there is medical witch power supply, 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.
