The description focuses on traditional blood pressure measurement methods (Auscultation and Oscillometric) and signal processing to improve accuracy, without mentioning AI or ML.
No
The device is a blood pressure monitor used for measuring and monitoring, not for treating any condition.
Yes
This device measures blood pressure and pulse rate, which are physiological parameters used to assess a patient's health status and can indicate the presence of conditions like hypertension. While it doesn't provide a definitive diagnosis, it collects data that is crucial for diagnostic purposes.
No
The device description explicitly lists included hardware components such as the main unit, cuffs, AC adapter, power cord, and an internal rechargeable battery. It also describes physical measurement methods involving a cuff and pressure sensors.
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 perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The description clearly states that this device is a blood pressure monitor designed to measure blood pressure and pulse rate in adult patients by wrapping a cuff around the upper arm. This is a non-invasive measurement taken directly from the body, not a test performed on a sample outside the body.
- Intended Use: The intended use is to measure blood pressure and pulse rate, which are physiological parameters measured directly from the patient.
- Measurement Method: The methods described (Auscultation and Oscillometric) are standard techniques for non-invasive blood pressure measurement.
Therefore, this device falls under the category of a non-invasive medical device used for monitoring physiological parameters, not an In Vitro Diagnostic.

Device Description
The BPBIO480KV is a digital monitor intended for use in measuring blood pressure and pulse rate in user population with upper arm circumference ranging from 22cm (8.6-inch to 16.5-inch). The systolic blood pressure and diastolic blood pressure are measured by non-invasive blood pressure ("NIBP") measuring method and also by utilizing the Auto auscultation method and Oscillometric method. The BPBIO480KV may provide useful clinical information about the current health status of not only the users who are diagnosed with hypertension but also those who are not diagnosed with hypertension. Warnings and cautions described in the user's manual should be observed at all times. Automated Auscultation is a method that combines the accuracy of auscultation, and the convenience of the Oscillometric method. To measure the blood pressure, wrap the cuff around the upper arm and inflate it to a pressure above the systolic pressure. Then slowly release the air to detect the Korotkoff sound signal and the pressure sensor signal, which you can listen with the stethoscope attached to the cuff, to measure the systolic and diastolic blood pressure. The Automated Auscultation applied to BPBIO480KV combines the accuracy of the auscultation method with the convenience of easy measurement. The signals are electronically processed to compensate for the possible errors in the auscultation method caused by movement, external noise, etc., enabling a more accurate blood pressure measurement. Included components are the main unit, a large and a medium size cuff, a users manual, an AC adapter, a power cord, and an internal rechargeable lithium rechargeable battery. Measurement methods: Auscultation and Oscillometric.

where the cuff is inflated to reach above the systolic pressure and then deflated. The blood pressure is measured using the pressure change in the blood flow while the cuff is being deflated. Systolic, diastolic, and mean pressure are estimated based on Oscillometric waveforms generated by the pressure changes. Compared to auscultation, it is convenient because it is easy to use and is less affected by external noise or movement, so it is widely used in automatic blood pressure monitors. However, conventional automatic blood pressure monitors, which use their own estimation algorithms, have problems with different measurements and poor accuracy. To perform a measurement, BPBIO480KV inflates the cuff above the systolic pressure and then deflates it to obtain the cuff pressure value and Korotkoff sound. As the pressure falls to the patient's systolic blood pressure, the first Korotkoff sound is heard. When the pressure drops below the diastolic pressure, it disappears after the last Korotkoff sound is heard. BPBIO480KV determines whether a Korotkoff sound is heard using the volume, distribution, Oscillometric signal, and filter of the sound acquired during the measurement, and determines the blood pressure value.
What is Auscultation? Auscultation is a method of measuring blood pressure directly using stethoscope, pressure gauge, and a cuff. It is the most traditional and a recognized standard. Wrap the upper arm with a cuff, inflate the cuff to pressurize the artery that passes under the skin to completely occlude the blood flow. Then release the air to reduce pressure, and use a stethoscope to listen to the sound from the pressed arteries when blood flows back into the pressed area. The sound generated at this moment is called the Korotkoff sound, and it is known to be caused by turbulence caused by the blood flow. As the pressure in the cuff falls to or below the patient's systolic blood pressure, some blood will be able to pass through the upper arm and the first Korotkoff sound is heard. Korotkoff sound continues to be heard as long as the pressure in the cuff is between the systolic and diastolic pressures, and it disappears altogether when the pressure in the cuff drops below the diastolic pressure. When the pressure in the cuff drops below the diastolic pressure, the cuff no longer interferes with blood flow, so there is no more audible sound as the blood flows without the turbulence.
This equipment tracks and analyzes the blood flow oscillations under the pressure using the cuff from the highest to the lowest pressure when the minute pressure speed is determined by the heartbeat. This equipment adopts Oscillometric method and automated auscultation method using a cuff for blood pressure measurement. In case of Oscillometric method, the device determines the systolic, diastolic and average pressure on the basis of the blood flow oscillations measured through the cuff. The point where the maximum amplitude of the blood flow oscillation appeared is the average pressure, the points where the 70% and 60% amplitudes appeared are the systolic and the diastolic pressure respectively. On the other hand, in case of Auto auscultation method, it is a method that combines the accuracy of auscultation, which is regarded as the gold standard for blood pressure measurement. To measure the blood pressure, wrap the cuff around the upper arm and inflate it to a pressure above the systolic pressure. Then slowly release the air to detect the Korotkoff sound signal and the pressure sensor signal, which you can catch with the stethoscope attached to the cuff, to measure the systolic and diastolic blood pressure. The Automated Auscultation applied to BPBIO480KV combines the accuracy of the auscultation method that the medical staffs hear directly with the convenience of easy measurement. The signals are electronically processed to compensate for the possible errors in the auscultation method caused by movement, external noise, etc., enabling a more accurate blood pressure measurement.
