No
The description details standard oscillometric blood pressure measurement and irregular pulse detection based on comparing time intervals, which are traditional signal processing techniques, not AI/ML. The document explicitly states "Not Found" for mentions of AI, DNN, or ML.
No.
The device is intended to measure blood pressure and pulse rate, and detect irregular heart rhythm; it does not provide therapy or treatment.
Yes
This device measures physiological parameters (blood pressure and pulse rate) and includes features like irregular pulse rhythm detection, which provides information about the user's health status. While it doesn't offer a definitive diagnosis, it provides data that can be used by healthcare professionals for diagnostic purposes or to alert users to potential health issues, fitting the general definition of a diagnostic device.
No
The device description explicitly details physical components like a cuff, main unit housing, microprocessor, pressure sensor, pump, valve, LCD, and batteries, indicating it is a hardware device with embedded software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
- Device Function: The Truly Automatic Wrist Bluetooth Blood Pressure Monitor DW702, DW703 measures blood pressure and pulse rate non-invasively by using a cuff wrapped around the wrist. It does not analyze any specimens taken from the body.
- Method: The device uses the oscillometric method, which is a physical measurement technique, not an in vitro diagnostic test.
Therefore, while it is a medical device used for health monitoring, it does not fit the definition of an In Vitro Diagnostic.

Device Description
Truly Automatic Wrist Bluetooth Blood Pressure Monitor DW702, DW703 are designed to measure the systolic and diastolic blood pressure and pulse rate of an individual by using a non-invasive technique in which an inflatable cuff is wrapped around the wrist. Our method to define systolic and diastolic pressure is similar to the auscultatory method but uses an electronic pressure sensor rather than a stethoscope and mercury manometer. The sensor converts tiny alterations in cuff pressure to electrical signals, by analyzing those signals to define the systolic and diastolic blood pressure and calculating pulse rate, which is a well-known technique in the market called the "oscillometric method".
The main components of the Truly Automatic Wrist Blood Pressure Monitor Dw series are the main unit and cuff unit. ABS is used to outer housing of the main unit. The preformed cuff unit, which is applicable to Wrist circumference approximately between 135 and 220 mm, includes the inflatable bladder and nylon shell. All models of the Wrist blood pressure monitor use a single size of cuff. The device consists of the microprocessor, the pressure sensor, the operation keys, the pump, the electromagnetic deflation control valve and the LCD. The subject devices are powered by four AAA alkaline batteries.
The devices also compares the longest and the shortest time intervals of detected pulse waves to mean time interval and displays a warning signal with the reading to indicate the detection of irregular pulse rhythm when the difference of the time intervals is over 25%.
The devices embed a Bluetooth 4.0 Wireless network connections module that allows it to connect to nearby receiving end. Once measurement is over, the LCD of device displays results, and the device will start to send out data such as systolic, diastolic, pulse, date, time with Wireless method and protocol.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Clinical Study.
Eighty-five subjects in the hospital were participated in clinical study.
Method: A standard mercury sphygmomanometer was used as a reference standard. Simultaneous and blinded blood pressure determinations were performed by two doctors.
Criteria: The ISO81060-2 Standard recommended:
- A. a mean difference of x5mmHg, with standard deviation of differences of x8 mmHg between test device and reference method.
- For the systolic and diastolic blood pressures for each of the m subjects, the standard B. deviation, the averaged paired the of sphygmomanometer-under-test and of the reference sphygmomanometer shall meet the criteria listed in Tab 1 when calculated according to Equation(3).
Result: Through clinical research, we can convinced that the clinical device is safe and effective.
