Summary
This study introduces a cost-effective, reliable mini-invasive system for long-term bladder urine pressure monitoring. The system uses a specialized amplifier to accurately measure bladder pressure, aiding in diagnosing various bladder conditions.
Area of Science:
- Biomedical Engineering
- Medical Devices
- Urology
Background:
- Accurate long-term bladder urine pressure monitoring is crucial for diagnosing and managing various bladder conditions.
- Existing systems may face limitations in cost, reliability, or power consumption for extended monitoring.
- Understanding intravesical pressure dynamics is key to assessing bladder function.
Purpose of the Study:
- To develop and present a mini-invasive system for cost-effective and reliable long-term bladder urine pressure measurement.
- To enhance system reliability and reduce design costs through innovative instrumentation.
- To enable continuous monitoring for extended periods, including during sleep and work activities.
Main Methods:
- Utilized a 1-atm canceling sensing instrumentation amplifier (IA) to enhance reliability and reduce cost.
- Implemented a system design incorporating sleeping and working modes to conserve battery power for long-term observation.
- Integrated a pressure sensor, IA, and analog-to-digital converter for signal amplification and conversion.
- Ensured the IA's capability to cancel intrinsic 1-atm bladder pressure for accurate linearity and resolution.
Main Results:
- The developed system demonstrates enhanced reliability and reduced design costs.
- The system effectively measures bladder urine pressure within a range of 14.7 to 19.7 Psi.
- The pressure measurement range covers all known unusual bladder syndromes or complications.
- The dual-mode (sleeping/working) operation conserves battery power for long-term monitoring.
Conclusions:
- The proposed mini-invasive system offers a reliable and cost-effective solution for long-term bladder urine pressure monitoring.
- The innovative use of a 1-atm canceling IA improves measurement accuracy and system robustness.
- The system's broad pressure measurement range and power-saving features make it suitable for clinical applications and managing diverse bladder pathologies.
