The description details the use of the oscillometric method and standard electronic sensors, with no mention of AI or ML algorithms for data analysis or interpretation. The performance studies also focus on standard electrical, mechanical, and environmental testing, not AI/ML validation.
No.
The device is used to measure blood pressure and pulse rate, which are diagnostic or monitoring functions, not therapeutic.
Yes
This device measures systolic and diastolic blood pressure and pulse rate, which are physiological parameters used to diagnose conditions like hypertension.
No
The device description explicitly mentions hardware components like an inflatable cuff, electronic capacitive pressure sensor, and an optional thermal printer. The performance studies also include testing related to electrical, mechanical, and environmental performance, further indicating it is not a software-only device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Device function: The Microlife Upper Arm Automatic Blood Pressure Monitor measures blood pressure and pulse rate by applying a cuff to the upper arm and using an oscillometric method. This is a non-invasive measurement taken directly from the body, not from a specimen collected from the body.
- Intended Use: The intended use clearly states it measures blood pressure and pulse rate of an adult individual using a non-invasive technique.
Therefore, based on the provided information, this device falls under the category of a non-invasive physiological monitoring device, not an In Vitro Diagnostic.

Device Description
The Microlife Upper Arm Automatic Blood Pressure Monitor, Model BP-3BTO-1 is 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 capacitive 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".
An optional printer is included as an accessory which can be sold separately in a separate box with the printer user manual.

rate, which is a well - known technique in the market called the "oscillometric method".
An optional printer is included as an accessory which can be sold separately in a separate box with the printer user manual.
Intended Use: 5.
The Microlife Upper Arm Automatic Blood Pressure Monitor, Model BP-3BTO-1, with Optional Thermal Printer, Model PR 1KA1, is a 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. This device can be used in connection with the Microlife Thermal Printer.
Comparison to Predicate Devices: 6.
Both devices use the well known oscillometric method within the software algorithm to determine the systolic and diastolic blood pressure and pulse rate. An upper arm cuff is inflated automatically; deflate rate is controlled by a factory set bleed valve and the deflation pressures are transferred via tubing to a sensor in both units. Each device uses a similar capacitance-type pressure sensor to translate the pressure variations to electrical signals that can be interpreted by an integrating circuit. Once the reading is determined each unit operates a solenoid valve to release the pressure to zero. Our Blood Pressure Monitor, Model BP-3BTO-1, differs from the predicate device in the fuzzy logic inflation.
The interface between the sensor and the microprocessor determines the system's accuracy. For our Pressure Monitor, Model BP-3BTO-1, the software is capable of a split slope resolution to improve accuracy over the entire range. Since the range is "split" into the three sections (0 to 100mmHg) (100 to 200mmHg) (200 to 300mmHg) error due to nonlinearity is reduced by the ability to adjunct the slope to best fit the output curve. A nonlinearity of 1% is reduced to 0.33% by splitting the span into three separated linear relations. This way the sensor is matched to the software by using a series of jumpers that profile the slopes to the output of the sensor.
The Microlife Automatic Blood Pressure Monitor, Model BP-3BTO-1, has field calibration access; this model is initiated by the following steps: (a) Remove one battery from compartment first, (b) When inserting back the battery, press and hold "I/O" key, and don't release it until the battery is inserted well.
