Electronic Stethoscope with Integrated Sonogram for Non-Invasive Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting cardiovascular or heart diseases are invasive, costly, and lack specificity, often requiring multiple tests that may not provide sufficient information for accurate diagnosis, necessitating a more convenient and effective diagnostic tool.
Innovation Solution
A stethoscope with a built-in sonogram and transducer that sends soundwaves through the chestpiece to a patient's skin, receiving echoed waves and transmitting them to an external monitor for real-time diagnosis, allowing for the detection of circulatory issues without the need for invasive procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional diagnostic methods (physical examination, stress testing, blood tests, coronary angiogram) are used to detect cardiovascular diseases, then diagnostic coverage is comprehensive, but the procedures are invasive, costly, and carry substantial risk to the patient
Solution Approach 1:
The patent combines the acoustic listening capability of a stethoscope with ultrasound imaging technology into a single integrated device. The chestpiece houses both traditional acoustic chambers and an ultrasound transducer, allowing simultaneous acquisition of both acoustic and sonographic data from the patient's body, thereby providing comprehensive diagnostic information through one non-invasive tool
Solution Approach 2:
The chestpiece is designed to perform multiple diagnostic functions: traditional acoustic auscultation for hearing heart and lung sounds, ultrasound imaging for visualizing internal structures and blood flow, and wireless data transmission for real-time monitoring. This multi-functional design eliminates the need for separate invasive procedures while maintaining comprehensive diagnostic capability
2Measurement precision
If multiple diagnostic tests are conducted to ensure accurate diagnosis of cardiovascular diseases, then diagnostic thoroughness is improved, but the time required and cost incurred increase significantly
Solution Approach 1:
The device merges multiple diagnostic modalities (acoustic sensing and ultrasound imaging) into a single simultaneous measurement process. Both types of data are collected at the same time during one patient encounter, eliminating the sequential nature of traditional testing and dramatically reducing the total time required for comprehensive cardiovascular assessment
Solution Approach 2:
The device performs preliminary non-invasive screening through acoustic and ultrasound measurements that can detect early signs of cardiovascular issues before more invasive procedures are needed. This preliminary assessment can identify patients who require further investigation and those who can be managed conservatively, reducing unnecessary invasive testing time
3Ease of operation
If traditional stethoscope is used for listening to heart and lung sounds, then the device is simple and easy to operate, but it cannot provide visual information about internal structures and blood flow
Solution Approach 1:
The device combines the familiar simple interface of a traditional stethoscope with advanced ultrasound imaging technology. The acoustic chambers and tubing remain for direct auditory feedback, while the integrated transducer provides visual sonographic images, giving practitioners both auditory and visual information through a single unified device that maintains operational simplicity
Solution Approach 2:
The chestpiece serves dual purposes: as a traditional acoustic listening device and as an ultrasound imaging probe. This allows the same simple-to-operate device to provide both auditory auscultation and visual imaging, eliminating the need for separate complex imaging equipment while maintaining ease of use
