Vibrating Gastrointestinal Capsule for Enhanced Drug Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for delivering medicaments to the gastrointestinal tract lack efficiency in absorption, particularly for conditions like Parkinsonism, where enhanced absorption and reduced dosage are desired without compromising therapeutic efficacy.
Innovation Solution
A vibrating gastrointestinal capsule system that, when ingested, uses a vibrating agitation mechanism to stimulate the enteric nervous system and increase peristalsis, enhancing the absorption of ingested medicaments within the gastrointestinal tract, allowing for potentially lower dosages and improved therapeutic outcomes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional medicament delivery methods are used, then the medicament is delivered to the gastrointestinal tract, but absorption efficiency is insufficient requiring higher dosages
Solution Approach 1:
The patent employs a vibrating capsule containing an eccentric rotating mass that generates mechanical vibrations and acoustic waves within the gastrointestinal tract. These vibrations stimulate the enteric nervous system and enhance peristalsis, thereby improving medicament absorption efficiency and reducing the required dosage
Solution Approach 2:
The capsule operates in periodic cycles, alternating between vibration phases and transit phases. The controller activates the vibration motor for specific durations at predetermined locations along the gastrointestinal tract, creating periodic stimulation that enhances absorption during critical time windows
2Reliability
If higher dosages are used to compensate for poor absorption, then therapeutic efficacy is maintained, but the risk of side effects increases
Solution Approach 1:
By changing the physical state of medicament delivery through vibration-induced enhancement of gastrointestinal motility and mucosal contact, the system achieves more reliable and consistent absorption. This improves therapeutic efficacy while reducing the need for high dosages that would otherwise be required to compensate for poor absorption
3Productivity
If the vibrating capsule is activated continuously, then absorption is enhanced throughout the entire transit, but energy consumption increases
Solution Approach 1:
The capsule employs periodic activation of the vibration motor rather than continuous operation. The controller activates vibrations at specific locations and times along the gastrointestinal tract, maintaining absorption enhancement during critical periods while conserving battery power during transit phases
Solution Approach 2:
The system dynamically adjusts its operation mode based on location and physiological conditions, transitioning between active vibration phases for enhanced absorption and passive transit phases for energy conservation, optimizing the balance between therapeutic effect and power consumption
4Productivity
If the capsule structure is made more complex to enable precise control and vibration mechanisms, then absorption enhancement is improved, but device complexity increases
Solution Approach 1:
The capsule integrates multiple functions into a single device: it serves as both a medicament delivery vehicle and an active absorption enhancement tool through integrated vibration and heating elements. The controller manages multiple functions (vibration, heating, tracking) within a unified system architecture
Solution Approach 2:
The patent combines the medicament delivery function with absorption enhancement functions by integrating the vibration motor, heating element, and controller directly into the capsule structure. This merging of functions achieves enhanced absorption capability while maintaining a relatively compact and manageable device design
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The vibrating capsule system increases the absorption of medicaments, enabling lower dosages while maintaining or improving therapeutic efficacy, and can be timed to coincide with the absorption period of ingested drugs, specifically benefiting conditions such as Parkinsonism.
Implementation Method 1
a vibrating agitation mechanism adapted such that, in a first vibrating mode of operation, the housing exerts vibrations on an environment surrounding the vibrating gastrointestinal capsule
Implementation Method 2
uses a vibrating agitation mechanism to stimulate the enteric nervous system and increase peristalsis, enhancing the absorption of ingested medicaments
