The device features include display of irregular pulse rhythm detection, classification display of measured blood pressure values against WHO (World Health Organization) guidelines, display of body movement detection and two memory account to save measurement results.

Device Story

Automatic oscillometric sphygmomanometer for home use; measures systolic/diastolic blood pressure, pulse rate, and pulse pressure via upper arm cuff. Input: pressure oscillations against cuff. Processing: analysis of pulse waves to determine blood pressure, pulse rate, pulse rhythm regularity, and body movement. Output: digital display of readings, WHO-based blood pressure classification, and irregular pulse detection. Operated by patient; powered by AA batteries or AC adapter. Benefits: enables self-monitoring of blood pressure and pulse in home setting; aids in tracking cardiovascular metrics over time.

Clinical Evidence

No clinical data submitted; substantial equivalence established via non-clinical bench testing and adherence to recognized standards (IEC, SP-10).

Technological Characteristics

Oscillometric measurement principle; upper arm nylon cuff; ABS and PMMA housing materials. Powered by 4 AA batteries or AC adapter. Features 15-digit LCD, irregular pulse detection, body movement detection, and 2-bank memory. Complies with IEC and SP-10 standards.

Indications for Use

Indicated for noninvasive measurement of systolic and diastolic blood pressure, pulse rate, and pulse pressure in adults in a homecare environment.

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.

Predicate Devices

Section (a) (1) Name of the submitter: Nihon Seimitsu Sokki Co., Ltd. Address: 2508-13 Nakago, Shibukawa, Gunma 377-0293, Japan Telephone number: 81-279-20-2311 Contact person: Mitsuo Kanai Date of documentation: September 14, 2011 - (2) Trade name of the device: Blood Pressure Monitor DSK-1011 Common name: Blood pressure monitor Classification: Noninvasive blood pressure measurement system, DXN, 870.1130, Class II - (3) Predicate devices: Model DS-1901 Digital Blood Pressure Monitor, K071384, Nihon Seimitsu Sokki Co., Ltd. and Wrist blood Pressure Monitor, Model WS-1100/WS-1100PV, K080177, Nihon Seimitsu Sokki, Co., Ltd. - (4) Description of the device: Blood Pressure Monitor DSK-1011 is an automatic sphygmomanometer to be used in a homecare environment. Blood pressure, systolic and diastolic, and pulse rate are taken at upper arm non-invasively using oscillometric method, which is one of the most common methods with recent automatic sphygmomanometer that determines blood pressure and pulse rate with oscillations against cuff applied to measurement site. The device consists of the main unit and the nylon cuffs, regular size cuff for arm circumference between 8.7 and 12.6 inches (between 220 and 320 mm) and large size cuff for arm circumference between 8.7 and 16.5 inches (between 220 and 420 mm), and is powered by four AA alkaline batteries or AC adaptor. The device not only determines blood pressure and pulse rate from oscillations but also analyses pulse wave and determines whether measurement was made with or without body movement and regularity of pulse rhythm. Besides these auxiliaries, user can get pulse pressure value and blood pressure level according to WHO guideline also on {1}------------------------------------------------ 14 the display. User can chose to activate clock function of the device to review measured readings with measurement date and time. - (5) Intended use of the device: DSK-1011 system is intended for noninvasive measurement of systolic and diastolic blood pressure, determination of pulse rate and calculation of pulse pressure in adults in a homecare environment. The device features include display of irregular pulse rhythm detection, classification display of measured blood pressure values against WHO (World Health Organization) guidelines, display of body movement detection and two memory account to save measurement results. The indication for use of DSK-1011 system is not exactly same with but similar to the predicate devices. The fundamental intended use, which is to measure adults' blood pressure non-invasively in home care environment, remains the same. The difference between the indications for use of the subject device and the predicate device lies in supplemental product features; some features of the predicate device are not provided with the new device and some new features are introduced with the subject device. As demonstrated in relevant sections of this submission, these features are concluded not to affect the device safety and effectiveness. - (6) Technological characteristics of the subject device and the predicate device: The subject device holds the same technological fundamentals with the predicate device, Model DS-1901 Digital Blood Pressure Monitor. Both devices consist of the main unit and the cuff for upper arm and powered with four AA alkaline batteries or designated AC adaptor. The patient contacting materials used for the subject device had been used with either one of the predicate devices, Model DS-1901 or WS-1100/WS-1100PV and these materials do not go through any different process from the predicate devices. The list of patient contacting materials and components is included in the relevant section of this application.
