Intended Use

The Essence 55SP Large Monitor System (Essence 55SP) is intended to be used by health care professionals to integrate the video output from various commercially-available instruments commonly used in a medical procedure laboratory into a single video display.

Device Description

The Essence 55SP Large Monitor System is a large color LCD monitor for viewing images derived from several video sources on a single display and to rearrange these images to the situational requirements of the user. The system consists of a 55" TFT color LCD Monitor, and optionally a video wall controller, optical graphic extension module, a common PC, and cables.

AI/ML Overview

The provided document is a 510(k) Summary for the Essence 55SP Large Monitor System. It describes the device and claims substantial equivalence to a predicate device. However, it does not contain the kind of detailed study information (sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, ground truth details for training/test sets) that would typically be found for an AI/ML medical device submission.

This document describes a medical monitor, not an AI/ML device. Therefore, the specific criteria requested, which are typically for assessing the performance of AI/ML algorithms against a clinical ground truth, are not applicable or present in this submission. The tests mentioned are performance tests for the display itself, ensuring it meets technical specifications and is equivalent to the predicate device.

Here's an attempt to answer the questions based on the available information, noting where the requested information is not present due to the nature of the device:

1. A table of acceptance criteria and the reported device performance

The document compares the proposed device (Essence 55SP) with a predicate device (Essence 55S) based on technical specifications. The acceptance criteria essentially appear to be demonstrating "substantial equivalence" to the predicate device, meaning its technical performance is either the same or, if different, the difference does not raise new questions of safety or effectiveness.

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

Not applicable. This is a medical monitor, and the "tests" performed are bench tests and display validation tests to confirm its technical specifications and equivalence to a predicate device. It does not process or analyze medical data in a way that would involve a "test set" of patient data.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

Not applicable. Ground truth, in the context of AI/ML, refers to clinically verified labels or diagnoses. This device is a display system, not a diagnostic AI. Its performance is assessed against technical specifications, not clinical judgment.

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

Not applicable. There is no test set in the sense of clinical cases requiring adjudication.

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 display monitor, not an AI system. It does not provide AI assistance for human readers, therefore, an MRMC study comparing human readers with and without AI would not be relevant.

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

Not applicable. This is a monitor, not an algorithm.

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

Not applicable. The performance is based on meeting technical specifications as specified by standards and comparison to a predicate device's measured performance. There is no "ground truth" related to medical disease states as one would find in an AI/ML submission.

8. The sample size for the training set

Not applicable. This is not an AI/ML device that requires a training set.

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

Not applicable. There is no training set or medical ground truth for this device.

The identified predicate within this submission is as follow:

Shenyang Torch-Bigtide Digital Technology Co., Ltd., Essence 55S Large Monitor System has been cleared by FDA through 510(k) No. K172969 (Decision Date - February 6, 2018).

{5}------------------------------------------------

5. Description of the Device [21 CFR 807.92(a) (4)]

The system consists of the following components:

  • A 55" TFT color LCD Monitor: HL5501SP ●
  • Video wall controller (AVS-540) (optional) ●
  • Optical graphic extension module-fibres detachable (M1-201SA-TR) (optional) ●
  • . A common PC (optional)
  • Cables (optional) .

The Essence 55SP Large Monitor System is a large color LCD monitor for viewing images derived from several video sources on a single display and to rearrange these images to the situational requirements of the user. Thanks to the advantages of the large widescreen monitor, the data can be collected from the video sources using the optional video wall controller AVS-540 and fed into the large display via the DVI lines and / or DP. DVI lines mean the assemblies consisting of DVI cable and related connectors; DP means the assembly consisting of DP cable and related connectors.

The optical graphic extension module M1-201SA-TR can be used to convert / transmit the video signal, and the common PC can be taken as a video device.

The difference between the Essence 55SP and the legally marketed device Essence 55S is additional glass. Essence 55S is without glass and Essence 55SP with glass, so Essence 55SP is named with the letter "P".

6. Intended Use [21 CFR 807.92(a)(5)]

  • Indications for Use:
    The Essence 55SP Large Monitor System (Essence 55SP) is intended to be used by health care professionals to integrate the video output from various commercially -available instruments commonly used in a medical procedure laboratory into a single video display.

7. Technological Characteristics [21 CFR 807.92(a)(6)]

The Essence 55SP Large Monitor System (Essence 55SP) uses a color LCD panel employing In-Plane Switching (IPS) technology to allow wide viewing angles. It is used in landscape mode.

{6}------------------------------------------------

When the various video sources from medical and other devices are being collected, they are being fed into the large Display via the corresponding lines and / or DP. The optional optical graphic extension module can be used as an optional part of the system to convert / transmit the video signal, and the optional PC can be taken as a video device.

The Essence 55SP Large Monitor System (Essence 55SP) may be provided in different housing colors and with different logos. The cosmetic differences do not affect the function and performance of the system.
