Implanted electronic siren to alarm for bladder full with urine

Area of Science:

• Biomedical Engineering
• Medical Devices
• Urology

Background:

• Accurate detection of bladder fullness is crucial for managing urinary incontinence and retention.
• Current methods may be invasive or lack real-time feedback.
• A non-invasive, reliable bladder fullness detection system is needed.

Purpose of the Study:

• To design and verify a device for detecting bladder fullness based on pressure measurement.
• To assess the feasibility of transmitting signals through biological tissues for remote alerting.

Main Methods:

• A liquid pressure sensor was integrated into a device to measure intravesical pressure.
• Pressure signals were processed, triggering an oscillator when exceeding 40 cmH2O.
• Signal transmission through a pig bladder and pigskin was tested to simulate body surface transmission.

Main Results:

• The device successfully measured bladder pressure and detected pressure exceeding the 40 cmH2O threshold.
• Oscillating signals were transmitted and received through biological tissue, demonstrating signal propagation feasibility.
• The system successfully triggered an alarm upon reaching the pressure threshold.

Conclusions:

• The designed device shows promise for non-invasively detecting bladder fullness.
• Signal transmission through biological tissues is feasible for remote alarm systems.
• Further development could lead to improved bladder management solutions.
