Input: cuff pressure alterations detected by electronic semiconductor sensor. Operation: oscillometric method; sensor converts pressure changes to electrical signals; software analyzes signals to calculate blood pressure and pulse. Usage: non-invasive; upper arm cuff; intended for adult individuals. Output: digital display of blood pressure and pulse rate. Clinical utility: provides automated, non-invasive vital sign monitoring for patient assessment. ## Clinical Evidence Clinical testing performed according to ANSI/AAMI-SP-10 standards (Section 4.4.2). Results met all required parameters. ## Technological Characteristics Non-invasive oscillometric blood pressure monitor. Uses electronic semiconductor sensor for pressure sensing. Powered by internal electronics. Form factor: upper arm cuff system. Software-based algorithm for signal processing. Tested for electrical, mechanical, and environmental safety per FDA 1993 guidance and IEC 60601-1. ## 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 - AMPLIFE Upper Arm Blood Pressure Monitor, Model M100 ([K043440](/device/K043440.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The assigned 510(k) number is: Kol 1279 AUG 1 8 2006 ## 1. Submitter's Identification: Little Doctor (Shanghai) Electronic Manufacture Co., Ltd Floor 30,1st Bldg ,No 4514 Caoan Road Shanghai China Tel: 0086-021-63056696 Date Summary Prepared: May 1, 2006 Contact: Mr. David Zhang ## 2. Name of the Device: LD-578 Fully Automatic Digital Blood Pressure Monitor ## 3. Common or Usual Name: Non-Invasive Blood Pressure Monitor System ## 4. Predicate Device Information: The LD-578 Fully Automatic Digital Blood Pressure Monitor, is substantially equivalent to the AMPLIFE Upper Arm Blood Pressure Monitor, Model M100, AMPLIFE Corporation. ## ട. Device Description: The LD-578 Fully Automatic Digital Blood Pressure Monitor, Model LD-578 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 semiconductor 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". {1}------------------------------------------------ # 6. Intended Use: The LD-578 Fully Automatic Digital Blood Pressure Monitor 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. # 7. Comparison to the Predicate Device: The LD-578 Fully Automatic Digital Blood Pressure and predicate device (AMPLIFE Upper Arm Blood Pressure Monitor, Model M100, K043440) are identical in functionality and performance with the difference being the external shape of the device, dimensional specification and clock function. These differences have no impact on safety or performance of the device. The blood pressure measurement algorithm and its functional technology are identical. Both the subject and predicate devices use the well known oscillometric method within the software algorithm to determine the systolic and diastolic blood pressure and pulse rate. ## 8. Discussion of Non-Clinical Tests Performed for Determination of Substantial Equivalence are as follows: Testing information demonstrating safety and effectiveness of the LD-578 Fully Automatic Digital Blood Pressure Monitor in the intended environment of use 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: - a. General Functions Test - b. Reliability Test-Operation Conditions - c. Reliability Test-Drop Testing - d. Reliability Test-Storage - e. Reliability Test-Vibrating Testing - EMC Testing ﺖ - g. IEC 60601-1 Safety Testing - h. FDA required Unit Intravariability Testing 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 LD-578 Fully Automatic Digital Blood Pressure Monitor tested met all relevant requirements of the aforementioned tests. {2}------------------------------------------------ ## 9. Discussion of Clinical Tests Performed: We have performed clinical testing on the LD-578 Fully Automatic Digital Blood Pressure Monitor according to "Clinical Data and Analysis ANSI/AAMI-SP-1000 Stondord -Saction 1-1 0" - Alto "Clinical Data and Analysis ANSI/AAMI-SP-10 Standard, Section 4.4.2". All testing results met required parameters. ## 10. Conclusions: We have demonstrated that the LD-578 Fully Automatic Digital Blood Pressure Monitor is as safe and effective as the predicate device based on electrical, mechanical and environmental testing results, and SP-10 standard requirements. FDA guidance document requirements were also met. Therefore, our subject device is as safe and effective as our predicate device. {3}------------------------------------------------ Image /page/3/Picture/0 description: The image shows the logo for the U.S. Department of Health & Human Services.
