This study introduces a novel multifunctional urine bag for enhanced patient monitoring. The device automates urine volume and pH monitoring, improving clinical decision-making and reducing nursing workload.
Area of Science:
- Biomedical Engineering
- Clinical Monitoring
- Urology
Background:
- Vital signs monitoring is common, but urine monitoring is often overlooked.
- Traditional methods for urine analysis (volume, pH) are manual and intermittent.
- There is a need for automated and continuous urine monitoring solutions in clinical settings.
Purpose of the Study:
- To design and develop a multifunctional urine bag for improved patient monitoring.
- To enable automated, real-time tracking of urine volume and pH.
- To assist healthcare professionals in clinical decision-making and reduce nursing tasks.
Main Methods:
- Development of a multifunctional urine bag with integrated alarm systems.
- Inclusion of a urine pH detection area within a hard plastic measuring bottle.
- Customizable alarm settings based on patient age and condition for urine volume per unit time.
Main Results:
- The designed urine bag accurately monitors urine volume per unit time.
- The device facilitates real-time, dynamic monitoring of urine pH.
- Potential for automated alarming of abnormal urine volume per unit time.
Conclusions:
- The multifunctional urine bag offers a significant advancement in urine monitoring.
- Automated monitoring of urine volume and pH can improve patient care and treatment planning.
- This innovation can help reduce the workload of clinical nursing staff.
