No
The summary describes standard oscillometric blood pressure measurement and analysis software, with no mention of AI or ML terms or methodologies.

No
The device is intended to measure blood pressure and pulse rate, which are diagnostic/monitoring functions, not therapeutic. It does not actively treat or alleviate a medical condition.

Yes

Explanation: The device measures blood pressure and pulse rate, which are physiological parameters used to assess and monitor health conditions. These measurements can aid in the diagnosis of various cardiovascular conditions, despite the device being intended for OTC use. For instance, high blood pressure readings can indicate hypertension.

No

The device description explicitly states it is a "rechargeable lithium battery-powered, automatic, noninvasive, wrist-worn blood pressure measuring system" that uses an "air pump" and "exhaust valve" to inflate and deflate a cuff. This indicates the presence of significant hardware components beyond just software.

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: The YUWELL® Blood Pressure Monitor measures blood pressure and pulse rate using a non-invasive method (oscillometric method) applied to the wrist. It does not analyze samples taken from the body.
  • Intended Use: The intended use is to measure blood pressure and pulse rate, which are physiological parameters, not to diagnose conditions based on in vitro analysis.

Therefore, this device falls under the category of a non-invasive medical device for monitoring physiological signs, not an In Vitro Diagnostic.

DISCUSSION OF DIFFERENCES

Note IDJustification
Note No.1,
Note No.2,
Note No.3
and Note
No.51) According to clause 5.1.3 of ANSI/AAMI/ISO 81060-2:2018,
adults or adolescent patients mean greater than 12 years old.
Additionally, adult means human being older than 12 based on
clause 3.1 of ANSI/AAMI SP-10:2002. So, both the proposed
device and predicate device are intended for adult whom more
than 12 years old. However, the proposed device which is not
suitable for neonate, pregnancy or pre-eclampsia tightens the
applicable population, thus decreases risks for those particular
population. In conclusion, the minor difference above will not
influence the safety and effectiveness of the devices.
2) While the proposed device is designed for household and medical
center use and the predicate device is for home use, the
difference will not influence the safety and effectiveness of the
devices because household environment is more complex.
3) The applicable wrist circumference of proposed device is
narrower than the predicate device, it will not raise any new or
different safety or effectiveness.
4) The proposed device can also detect the appearance of irregular
heartbeats during measurement and gives a warning signal with
readings, which is mentioned in "Features" and stated as
"Indication for irregular heartbeats". So, both devices are
identical for this.
Note No.4The pressure range and pulse rate of the proposed device are larger
than the predicate device, while the diastolic pressure range of the
proposed device is narrower. Both contain the blood pressure and
pulse range of most people, and the measurement range of
proposed device is fully verified according to IEC 80601-2-30.
Therefore, the differences do not bring additional risks.
Note No.6Although the "Power Supply" of the proposed device is different from
the predicate device, they all comply with IEC 60601-1, IEC 60601-
1-2, IEC 60601-1-11 and IEC 80601-2-30. Additionally, the
rechargeable lithium battery of the proposed device complies of IEC
62133-2, so this difference will not raise any safety or effectiveness
issue.
Note No.7
and Note
No.8Although the operating atmospheric pressure of the proposed device
is slightly broader than the predicate device, while the storage
temperature and humidity of the proposed device are little narrower,
they all comply with IEC 60601-1, IEC 60601-1-11 and IEC 80601-2-
30, so this difference will not raise any safety or effectiveness issue.
Note No.9
and Note
No.10Dimensions and weight of both devices are quite similar, and it
nearly makes no difference on safety and effectiveness of the
devices.
Note No.11
and Note
No.12Electric classification and rating of the two devices are different,
because the proposed device is Class II or internally powered ME
equipment, while the predicate device is internally powered ME
equipment. However, they all comply with IEC 60601-1, IEC 60601-
1-2, IEC 60601-1-11 and IEC 80601-2-30, so this difference will not
raise any safety or effectiveness issue.
Note No.13The voice broadcast function provides an additional way to get
measurement results except for visual. Therefore, option this
function whether or not for the proposed device doesn't affect normal
use of the device or influence the safety and effectiveness of the
devices.
Note No.14The proposed device can display measurement results by "mmHg"
or "kPa", while the predicate device can display by "mmHg" only.
The additional display unit meets the needs of more users and is
verified according to IEC 80601-2-30, so the difference will not raise
any new safety or effectiveness risk.
Note No.15The inflation icon is to help users identify increase of pressure in
cuff, corresponding to deflation icon indicating decrease of pressure,
so this would not raise any safety and efficacy problems.
Note No.16The proposed device has 3 minutes automatic power off time and it's
longer than the 2 minutes of the predicate device. The design
purpose is to give the user more time to review or record the data if
needed. The difference will not raise any new safety or effectiveness
risk.
Note No.17Although the calculating methods of average measurement value
are different, both the auxiliary functions contribute patients to check
the previous results, and don't affect the main function, so this would
not raise any safety and efficacy problems.
Note No.18Although the memory size of the proposed device was 26 fewer than
that of the predicate device, it was sufficient for users to view recent
measurement results, so this would not raise any safety and efficacy
problems.
Note No.19The Bluetooth transmission aims to record and view measurement
results on a mobile app when the device is not at hand. Therefore,
lack of Bluetooth transmission for YE8800CR and optional of
Bluetooth transmission based on users' order for YE8800AR don't
affect normal use of the device or influence the safety and
effectiveness of the devices.
