• Device Class: Class 2

Intended Use

KD-721 and KD-723 Fully Automatic Electronic Blood Pressure Monitor is for use by medical professionals or at home and is a non-invasive blood pressure measurement system intended to measure the diastolic and systolic blood pressures and pulse rate of an adult individual by using a non-invasive technique in which an inflatable cuff is wrapped around the wrist. The cuff circumference is limited to 14cm-25cm.

Device Story

KD-721 and KD-723 are fully automatic electronic blood pressure monitors for clinical or home use. Devices utilize oscillometric technology with silicon pressure sensors to measure systolic/diastolic blood pressure and pulse rate during cuff inflation. Users wrap the cuff around the wrist; device displays results on an integrated LCD and transmits data via Bluetooth to a smartphone app. Devices detect irregular heartbeats and provide blood pressure classification. Healthcare providers or patients use the output to monitor cardiovascular status. Benefits include non-invasive, convenient blood pressure tracking. Operation involves automated signal processing of pressure oscillations to calculate hemodynamic values.

Clinical Evidence

No new clinical testing performed. Clinical performance is bridged from the previously cleared KD-972 (K121470), which utilized the same algorithm (BPM-WAU V2.0-201109) and cuff specifications. The KD-972 clinical report conformed to ANSI/AAMI/ISO 81060-2:2009 & 2013 standards.

Technological Characteristics

Oscillometric measurement principle using silicon pressure sensors. Powered by 2x1.5V AAA batteries. Connectivity via Bluetooth for smartphone data transmission. Complies with IEC 60601-1, IEC 60601-1-2, and IEC 80601-2-30. Features integrated LCD display and irregular heartbeat detection.

Indications for Use

Indicated for adult individuals to measure diastolic and systolic blood pressure and pulse rate using a wrist-worn inflatable cuff (14cm-25cm circumference).

Regulatory Classification

Identification

A noninvasive blood pressure measurement system is a device that provides a signal from which systolic, diastolic, mean, or any combination of the three pressures can be derived through the use of tranducers placed on the surface of the body.
