Abstract

A microphone 1 or 3 is attached to a stethoscope to detect sounds picked up by the stethoscope. The microphone is connected to a display device 5 which provides a graphical representation of the sounds detected by the stethoscope. The device can also incorporate recording and playback of the detected sounds and may include a wristwatch or laptop based display.

Description

1. DESCRIPTION 1. 1. Title Heart Sounds Visual Aid.
1.2. Background One component of a routine medical examination involves the use of a stethoscope to listen to the heart sounds, and if present, murmurs. The findings are then recorded in medical casenotes in a graphical format, with vertical lines representing the physiological heart sounds, and additional sounds being recorded by shading in their relative amplitude, duration and position in the cardiac cycle.
The heart sounds visual aid is a device that displays the heart sounds on a screen, in a format that is readily transferable to the medical casenotes. The heart sounds visual aid allows the clinician to confirm the clinical auscultatory findings, and is applicable to health professional and students, providing a visual representation of auscultatory findings in a bedside setting.
1. 3. Essential Features The heart sounds are captured for the device by means of a microphone attachment to a stethoscope. The electronic information is passed to a screen for real-time display. Figure 1 (attached) shows a stethoscope and the heart sounds visual aid attached.
The microphone (1) is attached to the stethoscope by means of a clamp (2) onto either of the metal tubes that form its upper earpiece extensions.
Alternatively, by modifying the flexible plastic lower portion of the stethoscope to include an opening, the microphone may be inserted into the side of the tubing (3). Transfer of the captured signal is achieved via electrical cabling (4), or wireless transmission. The display screen (5) may be clipped onto the stethoscope; alternatively it can be incorporated into a wristwatch display, or utilise the screen of a palm-top computer.
1.4. Applications The primary application of the heart sounds visual aid is to allow health professional to confirm their clinical auscultatory findings prior to recording them in medical casenotes.
Subsidiary applications include the use of the heart sounds visual aid as a learning tool, which would be achieved by means of an audio playback of the heart sounds with simultaneous re-display of the visual representation.
Classification of the auscultatory findings by means of analysis software is permitted by capture of the electrical signal into a palm-top computer.

Claims (1)

  1. 2. CLAIMS The heart sounds visual aid is a device that displays a two-dimensional representation of the heart sounds, as heard with a stethoscope, in terms of signal amplitude versus time.
    The heart sounds are captured by means of attachment to, or modification of a stethoscope, and in its simplest form comprises a microphone and screen.
    The functionality of the device can be enhanced to include audio playback of the heart sounds, remote transfer of visual information to a wrist-mounted screen, or use of a palm-top computer for analysis and classification of the signal.
