The Bladder Scanner (model: PadScan Z3, PadScan Z3, PadScan Z5) is B-mode pulsed-echo ultrasound device. It intended as a handheld battery-operated device. The Bladder Scanner projects ultrasound energy through the lower abdomen of the patient to obtain images of the bladder which is used to calculate bladder Volume noninvasively. The Bladder Scanner is intended to be used only by qualified medical professionals.
The PadScan Series manufactured by AvantSonic Technology Co., Ltd. provides non-invasive volume bladder measurement utilizing real-time ultrasound imaging and measurement. The equipment consists of the main unit, 3D probe, battery and adapter. It features: Two Operation Modes: Expert Mode and Easy Mode, Non-invasive, comfortable, correct, reliable, fast and simple operation, Printouts with ultrasound images and various parameters through PC software, Touch screen keyboard operation, Urine volume setting and alarm setting, Multi-language selection, Combined power supply with AC adapter and a built-in battery. The difference between these models is the size of the LCD screen and enclosure structure. PadScan DS3 is provided 7-inch LCD screen. PadScan Z3 is provided 7-inch LCD screen and LCD screen stand. PadScan Z5 is provided 8-inch LCD screen and LCD screen which has a handle.
Here's a breakdown of the acceptance criteria and study information for the AvantSonic Bladder Scanner, based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
| Parameter | Acceptance Criteria (Predicate Device K131227) | Reported Device Performance (PadScan DS3, Z3, Z5) |
|---|---|---|
| Volume Measurement Accuracy | ±15%, ±15ml | ±10%, ±10ml |
2. Sample Size Used for the Test Set and Data Provenance
The document explicitly states: "Clinical testing is not required." This indicates that no clinical test set was used for the substantial equivalence determination. The performance criteria were based on comparisons to the predicate device's specifications.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
Not applicable, as no clinical testing with a test set requiring expert ground truth was conducted. Performance was based on device specifications and non-clinical testing.
4. Adjudication Method for the Test Set
Not applicable, as no clinical testing with a test set requiring adjudication was conducted.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No MRMC comparative effectiveness study was mentioned or performed. The submission relies on demonstrating substantial equivalence to a predicate device through non-clinical testing and shared intended use/technological characteristics.
6. Standalone (Algorithm Only) Performance Study
While the device calculates bladder volume non-invasively, the provided information does not detail a standalone algorithm performance study. The performance is assessed based on the device's ability to measure bladder volume within specified accuracy against a reference.
7. Type of Ground Truth Used
For the reported device performance regarding volume measurement accuracy, the ground truth would have been established through a controlled measurement method (e.g., using known volumes of liquid in a phantom or other controlled environment) to calibrate and verify the device's calculations. This is implied by the accuracy specification but not explicitly described as "pathology" or "outcomes data."
8. Sample Size for the Training Set
Not applicable, as this is a medical device submission based on substantial equivalence, not a machine learning model requiring a training set in the typical sense. The device's "training" is inherent in its design and calibration processes to meet the specified accuracy.
9. How the Ground Truth for the Training Set Was Established
Not applicable. See point 8. The device's volume calculation mechanism is based on ultrasound physics and established algorithms for bladder volume estimation, not trained on a distinct dataset with "ground truth" labels in the context of machine learning. The accuracy is verified through metrological testing.

Dear Mr. Wang:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. 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. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820);

§ 892.1560 Ultrasonic pulsed echo imaging system.
(a)
Identification. An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)
Classification. Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.
