Truly Automatic Arm Blood Pressure Monitor, Models DB33, DB81, DB82, DB83, DB85, DB91, DB92, DB93 are a series device intended to measure the systolic and diastolic blood pressure and pulse rate of an adult individual by using a non-invasive technique in which an inflatable cuff is wrapped around the upper arm.

Device Description
Truly Automatic Arm Blood Pressure Monitor DB series, Models DB33, DB81, DB83, DB85, DB91, DB92, DB93 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 upper arm. 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 Arm Blood Pressure Monitor DB 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 arm circumference approximately between 220 and 340 mm, includes the inflatable bladder and nylon shell. All models of the arm 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 AA alkaline batteries. The device 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%.
More Information

Not Found

No
The description details the use of the oscillometric method and a microprocessor to analyze pressure signals and detect irregular pulse rhythm based on time interval differences, which are standard signal processing techniques, not AI/ML. There is no mention of AI, ML, or related terms.

No.
The device is intended to measure blood pressure and pulse rate, and detect irregular heartbeats, which are diagnostic functions. It does not provide treatment or therapy.

Yes

The device measures systolic and diastolic blood pressure and pulse rate, and also features irregular pulse rhythm detection, which are all diagnostic indicators of a patient's health status.

No

The device description explicitly lists hardware components such as a main unit, cuff unit, microprocessor, pressure sensor, operation keys, pump, electromagnetic deflation control valve, and LCD. It also describes a physical process involving an inflatable cuff and pressure measurements.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. These tests are performed outside of the body (in vitro).
  • Device function: The description clearly states that this device measures blood pressure and pulse rate using a non-invasive technique involving an inflatable cuff wrapped around the upper arm. This is a measurement taken on the body (in vivo), not a test performed on a sample taken from the body.
  • Intended Use: The intended use is to measure blood pressure and pulse rate, not to perform diagnostic tests on biological samples.

Therefore, based on the provided information, this device falls under the category of a non-invasive physiological monitoring device, not an In Vitro Diagnostic.

  • Between-observer agreement should be: 95% or more of readings made simultaneously by observers agree to within x10mmHg and 85% or more agree to within x5 mmHg.
    Result: Through clinical research, we can convinced that the clinical device is safe and effective.
    Between test device and reference method:
    Systolic Pressure: Mean differences 3.3 mmHg, SD differences 5.2 mmHg
    Diastolic Pressure: Mean differences 4.5 mmHg, SD differences 4.6 mmHg

8. Conclusions

The new subject series devices of Truly Automatic Arm Blood Pressure Monitor continue to follow principles of hardware and software design of the predicate device DB61M(K091434), and the feature, safety, effectiveness are also as same as DB61M., just only in case and LCD''s size changes. Thus, the subject devices are substantially equivalent to the predicate devices.
