Endoscopy Pump Adaptive Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical pumps for endoscopy lack continuous, non-invasive blood pressure monitoring, leading to discontinuous pressure control in body cavities during procedures, which can result in inadequate fluid pressure adjustments and potential complications due to blood pressure fluctuations.
Innovation Solution
A medical device equipped with continuous, non-invasive blood pressure sensors, such as pulse oximeters or impedance sensors, that allow for real-time monitoring and automatic adjustment of fluid pressure in the body cavity to match the subject's blood pressure variations, ensuring precise control without disrupting blood flow or requiring surgical access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual pressure control is used in the body cavity, then bleeding can be stopped by increasing pressure, but the pressure cannot be dynamically adjusted to blood pressure fluctuations causing renewed bleeding or excessive pressure
Solution Approach 1:
The control unit continuously receives blood pressure measurements from the sensor and automatically adjusts the pump's fluid pressure accordingly. This closed-loop feedback system ensures the cavity pressure dynamically adapts to the patient's blood pressure fluctuations, preventing both renewed bleeding and excessive pressure complications.
Solution Approach 2:
The system transitions from static manual pressure setting to dynamic automatic pressure adjustment. The pump's pressure output continuously changes in response to real-time blood pressure measurements, allowing the system to adapt to varying physiological conditions during the procedure.
2Measurement precision
If classic blood pressure cuff is used for measurement, then blood pressure can be determined, but the measurement is discontinuous and requires measurement pauses to prevent tissue damage
Solution Approach 1:
The sensor enables continuous blood pressure monitoring throughout the procedure without interruption. Unlike intermittent cuff measurements, the continuous sensor provides uninterrupted blood pressure data, allowing the control unit to constantly adjust cavity pressure and eliminating measurement pauses that would interrupt the surgical procedure.
3Measurement precision
If invasive blood pressure measurement via catheter is used, then continuous blood pressure monitoring is possible, but surgical access is required
Solution Approach 1:
The sensor acts as an intermediary device that provides continuous blood pressure monitoring without requiring invasive catheter insertion. It offers a non-invasive alternative that achieves the measurement continuity of invasive methods while avoiding the surgical access and associated risks.
4Reliability
If pressure in the body cavity is increased to stop bleeding, then bleeding is controlled, but flushing fluid may be forced into blood vessels or tissue causing complications
Solution Approach 1:
The control unit uses real-time blood pressure feedback to precisely regulate cavity pressure, maintaining it just sufficient to control bleeding without exceeding safe levels. This prevents flushing fluid from being forced into blood vessels or surrounding tissue, eliminating the risk of post-operative complications from fluid leakage.
