Compensatory Container Pressure-Responsive Volume Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for high blood pressure, including medication and lifestyle changes, are often ineffective due to patient compliance issues and can have adverse effects, necessitating a device that can directly manage blood pressure without medication.
Innovation Solution
A compensatory container with a volume chamber and adjustable frame and flexible body that limits volume change at lower pressures and abruptly increases volume above a threshold, mimicking the natural 'windkessel' function to lower blood pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If medication and lifestyle changes are used to treat high blood pressure, then blood pressure can be managed, but patient compliance is poor and adverse effects occur
Solution Approach 1:
The implantable device automatically regulates blood pressure through its pressure-reactive volume change mechanism, eliminating the need for patient adherence to medication schedules or lifestyle modifications. The device serves itself by sensing pressure changes and autonomously adjusting vascular compliance.
Solution Approach 2:
The patent replaces the chemical/behavioral system (medication and lifestyle changes) with a mechanical system (implantable device with pressure-reactive volume chamber) that physically modulates blood pressure through volume displacement and elastic compliance.
2Stress or pressure
If the volume chamber allows free volume change with pressure, then blood pressure can be reduced, but volume change is excessive at normal pressures
Solution Approach 1:
The volume chamber exhibits different compliance characteristics at different pressure levels: it maintains rigid stability at normal pressures (below threshold) and becomes compliant at elevated pressures (above threshold). This localized quality change enables selective volume adjustment only when needed.
Solution Approach 2:
The device changes its physical parameter (volume) based on pressure threshold conditions. The volume chamber transitions from a stable, minimal-volume state at normal pressures to an expanded, high-volume state at elevated pressures, dynamically adjusting its parameters in response to physiological conditions.
3Stability of the object's composition
If the volume chamber is made rigid to maintain stability, then volume change is limited, but blood pressure cannot be effectively reduced at high pressures
Solution Approach 1:
The volume chamber transitions from a static, rigid state at normal pressures to a dynamic, compliant state at elevated pressures. This dynamic behavior allows the chamber to be stable when not needed and flexible when required for blood pressure control.
Solution Approach 2:
The volume chamber undergoes periodic expansion and contraction in response to cyclic blood pressure variations. During each cardiac cycle, the chamber expands during systolic pressure peaks and contracts during diastolic pressure drops, providing rhythmic blood pressure attenuation.

Function Achieved in This Case
Effectively reduces high blood pressure without medication by replicating natural blood vessel behavior, allowing minimal volume changes at normal pressures and significant changes at elevated pressures, thereby attenuating peak blood pressures.

AI summary
The invention concerns compensatory container (1) to influence blood pressure, comprising volume chamber (2) with connectors (3) for connecting volume chamber (2) to a natural cardiovascular system, and in which a change in pressure in the cardiovascular system may effect a change in volume of volume chamber (2), as well as means of adjustment which limit the change in volume of volume chamber (2) in a lower pressure region below a pressure threshold of at least 100 mmHg to a maximum of 10 cm3, and which, in an upper pressure region between the pressure threshold and 150 mmHg, effect a change in volume of volume chamber (2) of not less than 10 cm3, whereby the means of adjustment comprise frame (4) and at least one flexible body (5) working in conjunction with such frame. Frame (4) and flexible body (5) are located outside volume chamber (2), with frame (4) having two front parts (6) and at least three support rods (7) connecting two front parts (6), between which is situated the at least one flexible body (5).
