The document describes standard oscillometric and auscultatory blood pressure measurement methods and an internal algorithm for determining systolic and diastolic pressure, which is typical for digital blood pressure monitors and does not indicate the use of AI/ML. There is no mention of AI, ML, or related concepts like deep learning or neural networks.
No.
The device is a blood pressure monitor intended for measurement and detection, not for treating a condition or disease.
Yes
The device measures physiological parameters (systolic and diastolic pressure, and pulse rate) and detects irregular heartbeats, which are used to assess the health status of an individual and can aid in diagnosis.
No
The device description clearly outlines hardware components like an inflatable cuff, internal pump, internal exhaust valve, and an LCD display. It also describes physical processes like inflation and deflation. This indicates it is a physical medical device with integrated software, not a software-only device.
Based on the provided text, the UM-211 blood pressure monitor is not an In Vitro Diagnostic (IVD) device.
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 provide information about a person's health. These tests are performed outside of the body (in vitro).
- UM-211 Function: The UM-211 measures blood pressure and pulse rate by applying pressure to the upper arm and detecting the oscillations or sounds of blood flow. This is a direct measurement taken on the body, not a test performed on a sample taken from the body.
- No Sample Analysis: The description of the UM-211 does not mention the analysis of any biological samples.
Therefore, the UM-211 falls under the category of a non-invasive physiological monitoring device, not an IVD.

Intended Use / Indications for Use
UM-211 blood pressure monitor is designed to measure systolic, diastolic pressure, and pulse rate of adults who are twelve (12) years and older in the clinics and hospitals. The arm size is from 16 cm (6.3 inches) to 50 cm (19.7 inches). UM-211 can measure blood pressure in auscultatory (device class DXQ) and oscillometric (device class DXN) methods. It can detect irregular heartbeats and display a symbol on its display.

Device Description
UM-211 Digital Blood Pressure Monitors have the same design as the predicate devices with an inflatable cuff which is wrapped around the patient's upper arm. The blood pressure measurement starts with the inflation process by an internal pump. The systolic and diastolic blood pressures are determined by oscillometric method during the deflation process. The deflation rate is controlled by an internal exhaust valve. There is a quick exhaust mechanism so that the cuff pressure can be completely released immediately. Furthermore, there is a maximum pressure safety setting at 299 mmHg. UM-211 Digital Blood Pressure Monitor will not inflate the cuff higher than 299 mmHg. UM-211 will turn on an irregular heartbeat indicator if an irregular heartbeat was detected during the measurement process. For the oscillometric method, systolic and diastolic are determined by the internal algorithm. For the auscultatory method, systolic and diastolic are determined by the medical professionals. The results are shown on the LCD. The cuff is also deflated automatically to 0 mmHg at the same time. This auscultatory method is identical to the predicate device, UM-101 digital blood pressure monitor. The oscillometric method is identical to the predicate device with the capability to perform averaging function of multiple measurements (AOBP mode).
UM-211 also detects the patient daily activities and environmental conditions of ambient temperature and barometric pressure. These are non-medical features which will be only available for the medical professionals to review. These information are not displayed to the patient on the TM-2441 display. The BP waveform is another non-medical feature which can be used by the medical professional and A&D engineers to verify the accuracy of the blood pressure measurement. Basically, we can reconstruct the systolic, and pulse rate from the BP waveform. There is no other medical diagnose from the information of the BP waveform.
If the monitor receives no further action from the user for 1 minute, it will automatically turn off by itself and waiting for the next measurement timing. UM-211 has a memory capacity of 99 for the previous measurements.

8. Summary of Substantial Equivalence Modifications made from the predicate devices (UM-101 & UA-1000 series):
- · Modify the external industrial design for a different appearance.
- · Modify the internal layout of the circuit and components.
- · Increase the number of supported cuff size from 3 sizes to 4 sizes.
- · Power source Adding rechargeable battery
- · Combine the oscillometric and auscultatory methods
Discussion of standards used in the design verification and design validation
A&D Medical conducted design verification and design validation activities based on the comparison of the UM-211 with the predicate devices. Based on the changes, we conducted the appropriated test methodology and pass/fail criteria. After the tests were conducted, the test records were collected in the UM series design history file (DHF).
A&D Medical follows FDA recognized consensus standards and guidance documents in our medical device development and manufacturing processes. The following standards were used to for the design verification and valuation of UM series digital blood pressure monitors. These standards include three major groups. First group is the general quality system requirements. Second group is the special requirements for CDRH (870.1130). The third group is related to software and app life cycle processes requirements.

UM-211 met all applicable requirements of the FDA recognized consensus standards and guidance documents. None of the test demonstrated that UM-211 brings new issues of safety and effectiveness.
As a conclusion, UM-211 digital blood pressure monitor as described in its labeling and comparison analysis has not changed because of the modifications. The fundamental scientific technology of the modified device has not changed, either. There is no significant difference that affects the safety or effectiveness of the modified device as compared to the predicate devices.
