Intended Use

The device is a sphygmomanometer intended to be used with a stethoscope or Doppler for indirect measurement of arterial blood pressure. This device includes an aneroid gauge. Koven Technology, Inc. intends to provide the device for use by healthcare providers. Our product is for both hospital and clinical use and are intended for pediatric through adults, excluding neonates.

Device Description

The FAST Sphyg by Koven is an aneroid sphygmomanometer that uses the auscultatory blood pressure technique in combination with a stethoscope or Doppler and occluding cuff to determine systolic and diastolic blood pressure measurement. The FAST Sphyg includes an aneroid qauge, as well as a battery powered air pump so the user can control the inflation. When the activation button is pushed on the device, the air pump inflates the cuff. When the activation button is released, inflation stops, but the system remains pressurized. The aneroid gauge on the device reflects this increase in pressure, which is displayed in mmHg. A release valve is activated through a trigger switch to manually deflate the cuff and notate the blood pressure measurement.

AI/ML Overview

The provided text describes the FAST Sphyg by Koven, an aneroid sphygmomanometer intended for indirect measurement of arterial blood pressure. The document focuses on establishing substantial equivalence to a predicate device and adherence to relevant performance standards.

Here's an analysis of the provided information concerning acceptance criteria and supporting studies:

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

    The document does not present a single, consolidated table explicitly labeled "acceptance criteria" and "reported device performance" in the context of clinical accuracy for blood pressure measurement. Instead, it refers to compliance with performance standards, primarily ISO 81060-1:2007 Non-invasive sphygmomanometers - Part 1: Requirements and test methods for non-automated measurement type.

    However, the document lists other technical standards that the device meets, which can be considered acceptance criteria for electrical safety and electromagnetic compatibility:

    For the primary function of blood pressure measurement accuracy, the document states, "the FAST Sphyg has been designed and tested to meet the following standards: ISO 81060-1:2007 Non-invasive sphygmomanometers - Part 1: Requirements and test methods for non-automated measurement type." However, the specific accuracy acceptance criteria defined within ISO 81060-1 (e.g., mean difference and standard deviation between the device and reference method) and the actual reported performance data against these criteria are not detailed in this excerpt.

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

    This information is not provided in the excerpt. The document states that the device was "designed and tested to meet" ISO 81060-1:2007, but it does not describe the specific study, patient cohort, or sample size used for that testing.

  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):

    This information is not provided in the excerpt. For blood pressure measurement, the "ground truth" would typically come from a trained observer using a reference sphygmomanometer (e.g., mercurial sphygmomanometer or direct arterial measurement) following specific protocols, often involving multiple observers to mitigate bias (as per ISO standard requirements). However, no details on this are given.

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

    This information is not provided in the excerpt. Given that the device is a sphygmomanometer, adjudication would refer to how multiple measurements or observations by reference methods are reconciled, if applicable.

  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:

    This is not applicable to the FAST Sphyg by Koven. This device is a mechanical aneroid sphygmomanometer with a battery-powered pump, not an AI-assisted diagnostic tool for image analysis or interpretation.

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

    This is not applicable to the FAST Sphyg by Koven. It is a manually operated device where a healthcare provider uses a stethoscope or Doppler to interpret the Korotkoff sounds. There is no "algorithm" in the sense of an automated analytical process that provides a standalone reading without human involvement in the detection of sounds.

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

    For blood pressure measurement devices, the ground truth is typically established by simultaneous measurements using a recognized reference method, such as a mercurial sphygmomanometer or direct invasive arterial pressure measurement, performed by trained observers. The document, however, does not explicitly state the specific "type of ground truth" used in its testing beyond mentioning compliance with ISO 81060-1:2007, which dictates such methods.

  8. The sample size for the training set:

    This information is not applicable/not provided. As an analog medical device (aneroid sphygmomanometer), the FAST Sphyg does not involve machine learning or AI models, and therefore does not have a "training set" in the computational sense.

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

    This information is not applicable. See point 8.

General Overview:

The FAST Sphyg by Koven is an aneroid sphygmomanometer that uses the auscultatory blood pressure technique in combination with a stethoscope or Doppler and occluding cuff to determine systolic and diastolic blood pressure measurement.

The FAST Sphyg includes an aneroid qauge, as well as a battery powered air pump so the user can control the inflation. When the activation button is pushed on the device, the air pump inflates the cuff. When the activation button is released, inflation stops, but the system remains pressurized. The aneroid gauge on the device reflects this increase in pressure, which is displayed in mmHg. A release valve is activated through a trigger switch to manually deflate the cuff and notate the blood pressure measurement.

Clinical Applications:

Non-invasive arterial blood pressure measurement.

Principles:

Auscultatory blood pressure measurement:

As the heart beats, blood forced through the arteries cause a rise in pressure, called systolic pressure, followed by a decrease in pressure as the heart's ventricles prepare for another beat. This low pressure is called the diastolic pressure.

The sphygmomanometer inflates a cuff above expected systolic pressure using a pump. As the air release valve is opened, cuff pressure (slowly) decreases. When the cuff's pressure equals the arterial systolic pressure, blood begins to flow past the cuff, creating blood flow turbulence and audible sounds (called Korotkoff sounds). Using a stethoscope, these sounds are heard and the cuff's pressure is recorded. The blood flow sounds will continue until the cuff's pressure falls below the arterial diastolic pressure. The pressure when the blood flow sounds stop indicates the diastolic pressure.

Performance Standards:

No performance standards have been established for the FAST Sphyg under section 514 (864.5700) of the Federal Food and Drug Act. However, the FAST Sphyg has been designed and tested to meet the following standards:
