Intended Use
SKEEPER is an electronic stethoscope that collects, fitters, and amplifies the sound of a person's heart, lungs, and abdomen. It is intended for use by professional users in clinical environments or by lay users in non-clinical environments. It is not intended for self-diagnosis.
Device Description
SKEEPER is an electronic stethoscope used to collect and measure the sounds inside the body, and it consists of an electronic stethoscope (SM-300) and a mobile application (SKEEPER PRO APP). When the diaphragm at the bottom of the SM-300 is lightly attached to the body part to be measured, such as the heart, lungs, or abdomen, the diaphragm vibrates due to the sound inside the human body and generates a sound. This sound is collected using a microphone and converted into an electrical signal. After that, the electrical signal is filtered and amplified for each frequency band set according to the measurement site, amplified, and output to earphones or transmitted to the SKEEPER APP installed on the mobile platform, and then the sound is output the earphone or speaker of the corresponding platform. The SKEEPER PRO APP graphs the waveform of the sound received by the SM-300. It also stores and plays back sound data and analyzes heart rate.
More Information

No
The description focuses on basic signal processing (filtering, amplification) and data storage/playback. There is no mention of AI/ML terms, training/test sets, or performance metrics typically associated with AI/ML algorithms. The analysis of heart rate is a standard function for stethoscopes and doesn't necessarily imply AI/ML.

No
The device is an electronic stethoscope intended for collecting, filtering, and amplifying body sounds for diagnostic purposes, not for treating conditions.

No

Explanation: The "Intended Use" section explicitly states, "It is not intended for self-diagnosis." The device collects, filters, and amplifies sounds, and the app graphs waveforms and analyzes heart rate, but it is not presented as providing a diagnosis.

No

The device description explicitly states that SKEEPER consists of both an electronic stethoscope (SM-300) and a mobile application (SKEEPER PRO APP). The SM-300 is a hardware component that collects and processes sound before transmitting it to the software.

Based on the provided information, the SKEEPER device is not an In Vitro Diagnostic (IVD).

Here's why:

  • IVDs are used to examine specimens derived from the human body. The SKEEPER collects sounds directly from within the human body (heart, lungs, abdomen). It does not analyze blood, urine, tissue, or other biological samples.
  • The intended use is to collect, filter, and amplify sounds for listening and analysis of heart rate. This is a diagnostic tool that works by listening to internal body sounds, not by analyzing biological samples.

The description clearly indicates that the device is an electronic stethoscope used to collect and measure sounds inside the body. This aligns with the function of a traditional stethoscope, albeit in an electronic format with additional features like recording and analysis of heart rate.

Description of the Device 4.

SKEEPER is an electronic stethoscope used to collect and measure the sounds inside the body, and it consists of an electronic stethoscope (SM-300) and a mobile application (SKEEPER PRO APP).

When the diaphragm at the bottom of the SM-300 is lightly attached to the body part to be measured, such as the heart, lungs, or abdomen, the diaphragm vibrates due to the sound inside the human body and generates a sound. This sound is collected using a microphone and converted into an electrical signal. After that, the electrical signal is filtered and amplified for each frequency band set according to the measurement site, amplified, and output to earphones or transmitted to the SKEEPER APP installed on the mobile platform, and then the sound is output the earphone or speaker of the corresponding platform.

The SKEEPER PRO APP graphs the waveform of the sound received by the SM-300. It also stores and plays back sound data and analyzes heart rate.

Indication for Use

Subject, predicate, and reference devices are the same in that they collect, filter, and amplify sound inside the human body.

The subject and predicate devices are intended to be used by medical personnel and lay users in clinical and non-clinical environment.

Therefore, the indication for use of subject device is substantially the same as predicate device.

. Signal Input Method

The subjective device's signal input method is the same as that of the predicate device, which is different from the reference device.

. Frequency response range

The subjective device changes the frequency of the sound collected depending on the mode selection. A predicate device collects a wide range of sound frequencies in one mode. The reference device also has different collected frequencies depending on the mode.

The frequency band used throughout is 30 Hz to 2000 Hz for the target device and 20 Hz to 2000 Hz for the subject and reference devices. The frequencies used by the subject and reference devices are substantially equivalent because they cover the frequency bands used by the subject device.

. Functions

Sound Amplification, Volume Control, Record and Playback Sounds, Save & Share Recordings, Power Source, and wireless communication method are all the same for all devices.

. Application software

Using software to store, play, and graphically display sounds is all the same.

Predicate devices do not have the function of analyzing sound, but Reference devices do have the function of analyzing heart rate. This is the same as the function of analyzing heart rate for the Subject device.

Summary of Non-Clinical Data 7.

The following non-clinical data were provided in support of the substantial equivalence determination.

Electrical safety and electromagnetic compatibility(IEC 60601-1, IEC 60601-1-11, and IEC 60601-1-2), Biocompatibility(ISO 10993-1, ISO 10993-5, ISO 10993-10, ISO 10993-23), Software verification and validation (IEC 62304), Wireless coexistence (ANSI IEEE C63.27) and Bench testing

10. Summary of Clinical Data

Clinical Data was not required to demonstrate the substantial equivalence.

11. Conclusion

SKEEPER has the same intended uses and similar indications as the predicate device in that it filters and amplifies the sound of the human body. The two devices are also identical in that they send sound data to mobile applications for storage, playback, and visualization.

The difference between SKEEPER and predicate device is that SKEEPER's mobile application provides heart rate analysis, but predicate device's mobile application does not provide heart rate analysis. However, heart rate analysis is provided in the reference device's mobile application.

These functional differences do not introduce new intended uses and do not raise other concerns about safety and effectiveness when used as labeled.

Therefore, SKEEPER is substantially equivalent to a predicate device.
