The BL-M10 is a new platform treatment system with 12.1" display screen which combines IPL/ Diode Laser/Triple Diode Laser/ Picosecond Nd:YAG Laser/ 1064nm Long pulse Nd:YAG laser and Q-switch Nd:YAG Laser functions. This is 6 in 1 platform machine, that provides different function with attaching different hand pieces. The system is designed with a mains electricity (AC-powered) mobile (on wheels) assembly of devices that uses multiple therapeutic modalities in combination or in isolative and non-ablative treatment of skin surface. The system includes various energy sources and dedicated hand-pieces intended to apply the different energies to the skin for respective indications for use.

This device is a Multi-function Platform System (BL-M10) which includes IPL, Diode laser, Triple Diode laser, Picosecond Nd:YAG Laser, 1064nm Long pulse Nd:YAG, and Q-switch Nd:YAG laser functions. The acceptance criteria and supporting studies are presented through a substantial equivalence discussion with multiple predicate devices for each function.

A general acceptance criterion for all functions is that the differences between the subject device and the predicate device should not raise new concerns regarding intended use or safety.

Here's an analysis of the provided information:

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria are generally established by showing substantial equivalence to existing predicate devices. The reported device performance is demonstrated by comparing its features with those of the predicate devices. Since there are multiple functions and predicates, a combined table is challenging without further clarification of "acceptance criteria" beyond substantial equivalence. However, the document outlines feature-by-feature comparisons for each function, highlighting similarities and differences.

Let's extract a representative sample for the IPL function from "Tabel 1 Substantial equivalence discussion - IPL":

Similar tables are provided for Diode Laser, Triple Diode laser, Picosecond Nd:YAG Laser, 1064nm Long pulse Nd:YAG, and Q-switch Nd:YAG Laser functions.
The overall acceptance criterion is that any identified differences do not raise concerns regarding the intended use or safety of the subject device, which is concluded to be met for all functions.

2. Sample size used for the test set and the data provenance

The document states "VII.1. Non-Clinical Testing: A battery of tests was performed to verify that the proposed device met all design specification." and "VII.2. Performance Testing: Each handpiece underwent rigorous performance testing to verify adherence to specified energy output, wavelength accuracy, pulse duration, and spot size."
No specific sample size for a "test set" (e.g., number of devices or units tested) is provided. The testing is non-clinical.
Data provenance: The tests were conducted internally by Shanghai Bele Medical Technology Co., Ltd. for verification and compliance with standards. It is non-clinical testing.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. The document describes non-clinical testing for safety and performance characteristics, comparing technical specifications to predicate devices and recognized standards. It does not involve a "test set" requiring expert-established ground truth for diagnostic accuracy, for example.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. This section is for clinical studies involving human observers and diagnostic ground truth adjudication, which is not described.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This device is a laser/light treatment system, not an AI-powered diagnostic imaging device that assists human readers. No MRMC study was performed.

6. If a standalone (i.e. algorithm only, without human-in-the-loop performance) was done

Not applicable. This device is a medical instrument used by practitioners, not a standalone algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

For non-clinical testing, the "ground truth" for performance is based on engineering specifications, compliance with recognized international standards (e.g., IEC 60601 series, IEC 60825-1, IEC 62471), and direct measurement of physical parameters like energy output, wavelength, pulse duration, and spot size. For safety, the ground truth is compliance with the relevant safety standards.

8. The sample size for the training set

Not applicable. This submission describes a physical medical device, not a machine learning model that requires a training set.

9. How the ground truth for the training set was established

Not applicable. As stated above, this is not a machine learning device.
