Capstone Proposal
The stethoscope has been used for many years, and has been very effective to diagnose
certain cardiologic and pulmonologic sounds. It has also been used to listen to the heart sounds
of a fetus. For many years healthcare professionals would listen quietly to patients internal
organs so they could diagnose from specific sounds of such internal organs. A digital
stethoscope would be beneficial to healthcare professionals. A digital stethoscope would help a
healthcare professionals record their findings, either by a micro SD card or by USB. Once the
data is stored, the healthcare professionals can hear and graph the data. This would be quick and
more effective since there is a visual and audio representation to diagnose such cardiologic and
pulmonologic sounds. I would like to design a digital stethoscope that can evaluate a premature
ventricular contraction or (PVC), also known as ventricular premature beat (VPB), is a form of
irregular heartbeat in which the ventricle contracts prematurely. While some causes of such
phenomena are biological; other factors such as amphetamines and caffeine can also contribute
to such heart palpitation. Such phenomena of PVC are early warnings of severe cardiac
complications that may develop later on in life if the subject is does not receive treatment or
significantly change detrimental lifestyle habits.
Budget:
Minimum estimate $350
Maximum estimate $500
This design will entail the following,
As stated above the ultimate goal of this project is to help medical professional detect
cardiologically and pulmonologically problems that their patients are suffering from. In order to
meet this goal the device will be similar to both an EKG and a stethoscope, recording both
electrical signals and sounds originating from the heart. The device is intended to be comfortably
worn by the patients throughout the day. While worn the device will record data and store it to be
examined at a latter time by medical professionals. Displayed below are design parameters to
that will need to be meet for the device to be successful.
Digital Stethoscope Design Parameters:
• Transforming acoustic sound waves to electrical signals via microphone
• Record audio data on SD card or USB compatible memory
• Transmit audio data to a PC
Additional Design Parameters:
• Make it portable to be carried on one’s person
• Make a program to plot results and play audio
Scope of Work:
• Create Milestones and such Deadlines
• Develop System Design and Budget
• Develop Software
• Construct Module
