You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.

Device Information Trade Name/Common Name: MD-6000S Bladder Scanner Classification Name: Ultrasonic Pulsed Echo Imaging System (IYO) Diagnostic Ultrasound Transducer (ITX) Regulatory Class: Class II Regulation Number: 892.1560; 892.1570 Product Code: IYO; ITX ## 3. Predicate Devices Device Name: CUBEScan™ BioCon-1100 510(k) Number: K200548 Manufacturer: Mcube Technology Co., Ltd. ## 4. Device Description MD-6000S Bladder Scanner is intended to measure the volume of bladder. The device consists of a Main Unit and a 2.5 MHz 3D probe; the Main Unit is equipped with a color LCD touchscreen, a rechargeable Li-ion battery and a dock which integrates a thermal printer and AC power supply. Its software system is MD60SBLD V1.0. 004-1 {5} ## 5. Indications for Use MD-6000S Bladder Scanner is a B-mode pulsed-echo ultrasound device. It is intended to measure the volume of bladder. The device is intended to be used in medical and nursing care institutions. It should be used by appropriately trained and qualified healthcare professionals. ## 6. Comparison of Technological Characteristics The CUBEScan BioCon-1100 is a B-mode pulsed-echo ultrasound device. The BioCon-1100 projects ultrasonic energy through the lower abdomen of a patient to obtain images of the bladder to calculate the urine volume non-invasively. The BioCon-1100 is intended to be used by a qualified medical professional in hospitals and other healthcare facilities to non-invasively measure the urine volume in the bladder. Contraindications for the BioCon-1100 are fetal use and use on pregnant patients. The subject and the predicate devices are based on the following same technological elements: | Model Item | Subject Device MD-6000S Bladder Scanner | Predicate Device CUBEScan™ BioCon-1100 | | --- | --- | --- | | Display | 10.1 inch | 10.1 inch | | Volume Range | 0-999mL | 0-999mL | | Accuracy | ±7.5% or ±7.5mL, whichever is greater (based on phantom) | ± 7.5mL (0-99mL) ± 7.5% (100-999mL) | | Probe Mode | B-Mode scan image; 3D-Mechanical Sector Scan | B-Mode scan image; 3D-Mechanical Sector Scan | | Probe Scan Angel | 120° | 120° | | Printer | Built in Thermal Printer | Built in Thermal Printer | The differences of MD-6000S Bladder Scanner and its predicate device: | Model | Subject Device MD-6000S Bladder Scanner | Predicate Device CUBEScan™ BioCon-1100 | | --- | --- | --- | | Probe frequency | 2.5MHz | Dual frequency (2.8 MHz, 3.7MHz) | | OS | Android | Linux | | Power Supply | Power supply cord | Power adaptor | As it can be seen from the above tables, both MD6000S and CUBEScan BioCon-1100 are B-mode pulsed-echo portable ultrasound devices, and have the same intended use. The MD-6000S has similar performance characteristics, controls and indicators, and specifications as its equivalent device. It incorporates the same operational principles and technology as the BioCon-1100. The primary difference between the products is that: 004-2 {6} 1) MD-6000S uses a 2.5MHz ultrasound transducer and BioCon-1100 uses Dual frequency (2.8 MHz, 3.7MHz) ultrasound transducer. 2) The MD-6000S runs on Android, while the BioCon-1100 runs on Linux. 3) The MD-6000S is powered by an internal switching power supply connected via a power cord, whereas the BioCon-1100 is powered by an external adapter. Although there are some differences between the MD-6000S and BioCon-1100, they have no substantial impact on the intended use, safety and effectiveness of the device. ### 7. Brief Discussion of Non-clinical Tests The device has been verified to meet the following requirements, with all verifications passed: #### Safety and EMC: The safety and EMC testing were conducted on the MD-6000S and the testing results comply with the requirements of the following standards: IEC 60601-1:2005, IEC 60601-1:2005/AMD1:2012, IEC 60601-1:2005/AMD2: 2020 and AAMI ES60601-1:2005, AAMI ES60601-1:2005/ AMD1:2012, AAMI ES 60601-1:2005/ AMD2:2021 Medical electrical equipment - Part 1: General requirements for basic safety and essential performance IEC 60601-1-6:2010, IEC 60601-1-6:2010/AMD1:2013, IEC 60601-1-6:2010/AMD2:2020 Medical electrical equipment - Part 1-6: General requirements for basic safety and essential performance-Collateral standard: Usability for use in conjunction with IEC 62366-1:2015, IEC 62366-1:2015/AMD1:2020 Medical devices - Part 1: Application of usability engineering to medical devices IEC 60601-2-37: 2024 Medical electrical equipment-Part 2-37: Particular requirement for the basic safety and essential performance of ultrasonic medical diagnostic and monitoring equipment IEC 60601-1-2: 2014/AMD1: 2020 Medical electrical equipment - Part 1-2: General requirements for basic safety and essential performance - Collateral Standard: Electromagnetic disturbances - Requirements and tests IEC TR 60601-4-2: 2016 Medical electrical equipment - Part 4-2: Guidance and interpretation - Electromagnetic immunity: performance of medical electrical equipment and medical electrical systems #### Acoustic output parameters: The acoustic output parameters comply with the requirements of: NEMA UD 2-2004 (R2009) Acoustic Output Measurement Standard for Diagnostic Ultrasound Equipment Revision 3, and FDA Guidance document Marketing Clearance of Diagnostic Ultrasound Systems and Transducers issued on February 21, 2023 #### Biocompatibility: 004-3 {7} The biocompatibility evaluation has been conducted according to ISO 10993-1:2018 Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process. Tests for in vitro cytotoxicity, skin sensitization and skin irritation were conducted on the patient-contacting materials according to the requirements of: ISO 10993-5: 2009 Biological evaluation of medical devices - Part 5: Tests for in vitro cytotoxicity ISO 10993-10: 2021 Biological evaluation of medical devices - Part 10: Tests for skin sensitization ISO 10993-23: 2021 Biological evaluation of medical devices - Part 10: Tests for irritation # **Bench Testing:** Measurement accuracy of ±7.5% or ±7.5 mL within the measurement range of 0 mL – 999 mL For the measurement range of 100 mL – 999 mL, use MD-6000S Bladder Scanner to make scan on the phantom and compare the measurement value and the nominal value, the measurement accuracy met the requirements of ±7.5%. For the measurement range of 0 mL – 99 mL, use MD-6000S Bladder Scanner to make scan on the phantom and compare the measurement value and the nominal value, the measurement accuracy met the requirements of ±7.5mL. # **Clinical Validation Study:** Two clinical studies were conducted to evaluate the accuracy of the MD-6000S Bladder Scanner in measuring bladder volume — one enrolling pediatric and adult volunteers, and a second focused on individuals with high BMI. The studies assessed measurement accuracy across different bladder volume ranges and BMI levels, using Bland-Altman statistics and 95% limits of agreement as the analytical framework. Accuracy requirements were pre-defined and applied consistently across both studies. Based on statistical analysis of test data, good agreement is confirmed between MD-6000S measurements and voided-urine-volume reference values. # **8. Conclusions** The results of non-clinical tests as well as the software and essential performance verification and validation demonstrate that the MD-6000S Bladder Scanner is substantially equivalent in safety, effectiveness and performance to the legally marketed predicate device. 004-4 --- **Source:** [https://fda.innolitics.com/device/K260313](https://fda.innolitics.com/device/K260313) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
