Healthcare providers use output for clinical assessment of patient cardiovascular status. Benefits: non-invasive, automated monitoring of blood pressure. ## Clinical Evidence Clinical testing performed per ANSI/AAMI SP10-1992 'National Standard for Electronic or Automated Sphygmomanometers'. Device met all relevant requirements of the standard. ## Technological Characteristics Oscillometric measurement; electronic capacitive pressure sensor; microprocessor-based; fuzzy logic inflation control; split slope resolution software (three linear segments); solenoid valve for pressure release; optional thermal printer accessory; field calibration access via battery/key sequence. ## Regulatory 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 - Microlife Automatic Blood Pressure Monitor, Model BP-2BHO ([K970211](/device/K970211.md)) ## Related Devices - [K193624](/device/K193624.md) — Automatic Upper Arm Blood Pressure Monitor · Dongguan E-Test Technology Co., Ltd. · Jul 10, 2020 - [K193627](/device/K193627.md) — Automatic Upper Arm Blood Pressure Monitor · Dongguan E-Test Technology Co., Ltd. · Jul 12, 2020 - [K170605](/device/K170605.md) — Upper Arm Type Electronic Blood Pressure Monitor Series, Electronic Blood Pressure Monitor: YE650A, YE650D, YE660B, YE670A and YE670D · Jiangsu Yuyue Medical Equipment & Supply Co., Ltd. · Mar 27, 2018 - [K070828](/device/K070828.md) — KD-595 FULLY AUTOMATIC ELECTRONIC BLOOD PRESSURE MONITOR · Kodon(Tianjin)Electronic&Electrical Apparatus Co., · Aug 15, 2007 - [K221913](/device/K221913.md) — Arm Blood Pressure Monitor · Alicn Medical Shenzhen, Inc. · Oct 12, 2022 ## Submission Summary (Full Text) {0}------------------------------------------------ # EXHIBIT # 1 # 510(K) SUMMARY This summary of 5l0(k) safety and effectiveness information is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR §807.92. The assigned 5l0(k) number is: #### 1. Submitter's Identification: Microlife Corporation 9F, 431 Rui Guang Road Nei Hu. Taipei 114 Taiwan, Republic of China ## Contact: Mr. Laurence Yanq Date Summary Prepared: October 17, 2001 #### 2. Name of the Device: Microlife Upper Arm Automatic Blood Pressure Monitor, Model BP-3BTO-1, with Optional Thermal Printer, Model PR 1KA1. #### 3. Predicate Device Information: The Microlife Upper Arm Automatic Blood Pressure Monitor, Model BP-3BTO-1 is substantially equivalent to the Microlife Automatic Blood Pressure Monitor, Model BP-2BHO, K# 970211. #### 4. 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 {1}------------------------------------------------ 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. ### Discussion of Non-Clinical Tests Performed for Determination of 7. Substantial Equivalence are as follows: {2}------------------------------------------------ Testing information demonstrating safety and effectiveness of the Microlife Automatic Blood Pressure Monitor, Model BP-3BTO-1 in the intended Automatio Drosa is supported by testing that was conducted in accordance with the FDA November 1993 Draft "Reviewer Guidance for Premarket Notification Submissions", DCRND, which outlines Electrical, Mechanical and Environmental Performance Requirements. The following testing was conducted: - General Functions Test a. - Reliability Test Operation Conditions b. - Reliability Test Drop Testing C. - Reliability Test Storage ರ. - Reliability Test Vibrating Testing e. - f. EMC Test - IEC 60601-1 Safety Test g. - Blood Pressure Monitor Printer Port Function Test Report h. - Thermal Printer Software Validation Report .... - EMC Test Report Blood Pressure Monitor Connected with j. Thermal Printer None of the testing demonstrated any design characteristics that violated the requirements of the Reviewer Guidance or resulted in any safety hazards. It was our conclusion that the Microlife Upper Arm Automatic Blood Pressure Monitor, Model BP-3BTO-1 tested met all relevant requirements of the aforementioned tests. #### Discussion of Clinical Tests Performed: 8. ANSI/AAMI SP10-1992 "National Standard for Electronic or Automated Sphygmomanometers" testing was performed. All relevant sections were addressed and testing conducted. The BP-3BTO-1 met all relevant requirements of this standard. #### 9. Conclusions: We have demonstrated that the Microlife Automatic Blood Pressure Monitor, Model BP-3BTO-1, is as safe and effective as the predicate, the Microlife Automatic Blood Pressure Monitor, Model BP-2BHO based on electrical, mechanical and environmental testing results as well as the FDA DCRND November 1993 Draft "Reviewer Guidance for Premarket Notification Submissions", and, the ANSI/AAMI Voluntary Standard, SP10-1992 testing results. {3}------------------------------------------------ Image /page/3/Picture/2 description: The image shows the seal of the Department of Health & Human Services (HHS) of the United States of America.
