This Blood Pressure Monitor is intended for use in measuring blood pressure and pulse rate in patients with arm circumferences from 16 to 36 cm (6.3 to 14.1 inch) or 22 to 45cm (8.6 to 17.7 inch). Cuff model AC1636-01, arm circumference range is 16-36cm (6.3 to 14.1 inch), which is intended for children older than 3 years old or adults without conditions of diabetes, pregnancy, or pre-eclampsia. Cuff model AC2245-021, arm circumference range is 22-45cm (8.6 to 17.7 inch), which is intended for adult population or those who with conditions of diabetes, pregnancy, or pre-eclampsia. It is intended indoor use only.
Device Description
The Blood Pressure Monitor is designed to measure the systolic 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 Blood Pressure Monitor is 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 160mm and 450 mm, includes the inflatable bladder and polyester shell. The device consists of the microprocessor, the pressure sensor, the operation keys, the electromagnetic deflation control valve and the LCD. The devices embed a Cellular Wireless network connections module that allows it to 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 rate, date and time by Wireless method and protocol.

It also describes a physical method of measurement using an inflatable cuff.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are 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: This device is a Blood Pressure Monitor. It measures blood pressure and pulse rate non-invasively by applying a cuff to the upper arm. It does not analyze any biological specimens taken from the body.
  • Intended Use: The intended use is to measure blood pressure and pulse rate in patients, not to analyze biological samples.
  • Device Description: The description details the mechanical and electronic components used for non-invasive measurement, not for analyzing biological samples.

Therefore, this Blood Pressure Monitor falls under the category of a medical device, but specifically a non-invasive physiological monitoring device, not an In Vitro Diagnostic device.

PrincipleThis product uses the
Oscillometric Measuring
method to detect blood
pressure.
Before every measurement, the
unit establishes a "zero
pressure" equivalent to the
atmospheric pressure. Then it
starts inflating the arm cuff,
meanwhile, the unit detects
pressure oscillations generated
by beat-to-beat pulsatile, which
is used to determine the systolic
and diastolic pressure, and also
pulse rate.This product uses the
Oscillometric Measuring method
to detect blood pressure.
Before every measurement, the
unit establishes a "zero pressure"
equivalent to the atmospheric
pressure. Then it starts inflating
the arm cuff, meanwhile, the unit
detects pressure oscillations
generated by beat-to-beat
pulsatile, which is used to
determine the systolic and
diastolic pressure, and also pulse
rate.The subject device uses the
Oscillometric Measuring method
to detect blood pressure. The
device detects blood pressure
measurement on the inflation.
Before every measurement, the
unit establishes a "zero pressure"
equivalent to the air pressure.
Then it starts inflating the cuff
with the inflation rate 7mmHg/s,
meanwhile, the device detects
pressure oscillations generated by
beat-to-beat pulsatile. Then the
measurement finishes, and the
device starts deflating. Deflation
occurs in step intervals based on
the cuff pressure. The deflation
step range is about 6-12 mmHg.
Higher cuff pressure corresponds
to the larger pressure deflation
step.Oscillometric methodSame
