Oscillating Agitator for Controlled Hemostatic Agent Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscopic medical procedures face challenges in controlling the delivery rate of hemostatic agents, leading to inconsistent dosing and potential clogging of delivery devices, which can hinder effective hemostasis in the gastrointestinal tract.
Innovation Solution
A medical device featuring an enclosure with an oscillating agitator that uses pressurized fluid to move a hemostatic agent through a delivery tube, ensuring controlled and consistent delivery by creating pressure changes and utilizing a diaphragm and walls to facilitate movement of the agent towards the outlet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pressurized fluid systems are used to deliver hemostatic agent, then the agent can be delivered to the treatment site, but the delivery rate cannot be controlled and may result in clogging or inconsistent dosing
Solution Approach 1:
The system transitions from static pressurized delivery to dynamic peristaltic pumping, where the delivery mechanism actively changes its state through sequential compression and relaxation of delivery sections, enabling controlled and consistent agent delivery rates
Solution Approach 2:
The patent replaces the traditional pressurized fluid system with a peristaltic pumping mechanism that uses mechanical compression of flexible delivery sections to propel the agent, eliminating the uncontrolled pressure-driven flow and enabling precise delivery rate control
2Speed
If high pressure is used to deliver agent through delivery tube, then the agent reaches deep within GI tract, but the delivery device may clog
Solution Approach 1:
The system uses dynamic peristaltic waves that sequentially compress and relax delivery sections, creating controlled propulsion that maintains sufficient speed to reach deep GI tract sites while avoiding the high pressure that causes clogging
Solution Approach 2:
The delivery tube is divided into multiple flexible sections that can be independently compressed and relaxed, allowing the agent to be propelled forward in controlled segments rather than through uncontrolled high pressure, preventing clogging while maintaining delivery speed
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 device enables precise and efficient delivery of hemostatic agents to the target site, reducing the risk of clogging and ensuring consistent dosing, thereby enhancing hemostasis and procedural efficiency.
Implementation Method 1
The agitator is configured to create pressure change within the enclosure via oscillation of the agitator relative to the enclosure
Implementation Method 2
an agitator positioned adjacent to or within the enclosure and configured to oscillate relative to the enclosure
Data Source
AI summary
A medical device that includes an enclosure for storing an agent, an agitator positioned adjacent to or within the enclosure and configured to oscillate relative to the enclosure, and an outlet having a first end in fluid communication with the enclosure and a second end in fluid communication with a channel of a delivery tube. Oscillation of the agitator causes the agent to move toward the outlet.
