- Normal auscultation of the cardiovascular system, pulmonary system or gastro-intestinal system by a health care professional.
- Normal auscultation as above by a health care professional who wears hearing aids.
- To allow four other listeners (e.g. students) to listen together with a health care professional.
An electronic stethoscope utilizing conventional stethoscope components but amplifying auscultated sounds by means of a 3 volt electronic circuit. An output jack is provided for headphone use. The stethoscope is controlled by a single button which turns the unit on and adjusts the amplitude through four levels.
The provided document states that no clinical tests were performed for the GEMINI E Electronic Stethoscope.
Therefore, the following information cannot be extracted from the document:
- A table of acceptance criteria and the reported device performance: Not applicable as no clinical tests were performed to establish performance metrics against acceptance criteria.
- Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective): Not applicable.
- 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.
- Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable.
- 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. The device is an electronic stethoscope, not an AI-assisted diagnostic tool.
- If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
- The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable.
- The sample size for the training set: Not applicable.
- How the ground truth for the training set was established: Not applicable.
The document indicates that the determination of substantial equivalence was based on non-clinical tests, specifically:
- Emissions testing conducted by Acme Laboratories in Acme, Washington.
- Safety testing in accordance with government requirements conducted by Intertek Testing Services in Laguna Niquel, California.
The conclusion states that the GEMINI E stethoscope is substantially equivalent to the Simulscope Bedside Auscultation System in its applications and that safety has been established through these non-clinical tests.
