Rectal Medication Device Balloon Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional rectal medication administration methods, such as suppositories and gels, are invasive and uncomfortable for patients and caregivers, especially when patients have hemorrhoids, and require repeated repositioning, which can be painful and challenging, especially for hospice patients who have lost the ability to swallow.
Innovation Solution
A medication administration device with a tip portion having multiple holes and a balloon that can be inflated to secure the device within the rectum, allowing for continuous or intermittent medication delivery through a port system connected to a syringe, minimizing the need for repeated insertion and reducing discomfort by maintaining the device in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional rectal medication administration using suppositories and gels is employed, then medication delivery is achieved, but the procedure becomes invasive and uncomfortable requiring repeated patient repositioning
Solution Approach 1:
The device is divided into distinct functional segments: a tip portion with multiple holes for medication distribution, a balloon portion for anchoring, and a port portion for syringe connection. This segmentation allows each component to perform its specific function independently, enabling reliable medication delivery while eliminating the need for repeated invasive insertions.
Solution Approach 2:
The balloon is inflated within the rectum to secure the device in place before medication administration begins. This preliminary anchoring action prevents the need for repeated repositioning during the medication delivery process, significantly improving patient comfort while maintaining reliable medication administration.
2Reliability
If traditional rectal administration methods are used, then medication can be delivered, but repeated insertion and repositioning is required which increases procedure complexity
Solution Approach 1:
Multiple functions are merged into a single device structure: the tip portion with holes delivers medication, the balloon portion anchors the device, and the port portion enables syringe connection. This integration allows all medication administration functions to be performed through one insertion, reducing procedural complexity while maintaining reliable medication delivery.
Solution Approach 2:
The device enables continuous medication administration through the port portion after single insertion. The balloon maintains continuous anchoring, and the port allows continuous or intermittent medication delivery without requiring repeated insertions, thereby simplifying the overall procedure.
3Device complexity
If medication is delivered through a single lumen, then the device structure is simple, but medication volume requirements increase leading to dilution
Solution Approach 1:
The internal structure is segmented into two separate lumens: a first lumen for medication delivery and a second lumen for balloon inflation. This segmentation allows medication to be delivered through a narrow bore without requiring large volumes, as the medication flows directly to the tip holes without being diluted in a large single lumen space.
4Reliability
If the tip portion is inserted deep into the rectum, then medication reaches the distal portion effectively, but device length increases making insertion more difficult
Solution Approach 1:
The tip portion is designed with multiple holes distributed across its surface, creating local medication distribution points throughout the distal rectum. This local quality approach allows effective medication distribution to be achieved with a shorter overall device length, as multiple localized delivery points replace the need for extremely deep single-point insertion.
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 comfortable, efficient, and prolonged medication delivery to the rectum without the need for frequent repositioning, reducing pain and discomfort for patients and simplifying the process for caregivers, while maintaining effective medication absorption.
Implementation Method 1
a balloon defining a balloon cavity. When the balloon is deflated the tip portion can be inserted into a body cavity, such as the rectum... The balloon is configured to prevent the tip portion from being withdrawn from the body cavity and, in at least some embodiments, to hold medication within the rectum after the balloon is inflated inside the body cavity
Implementation Method 2
The rectum is a good alternative for hospice patients when the oral route fails. The walls of the rectum absorb many medications fast and effectively

AI summary
A rectal medication administration device includes a tube, a balloon, a first valved port, and a second valved port. The tube includes a first lumen, a second lumen, and a plurality of holes extending from the first lumen therethrough. The balloon is proximal to the holes, is in communication with the second lumen, and is configured to be inflated to hold the tube in place within a patient's rectum. The first valved port is in communication with the first lumen and opens when connected to a first syringe or infusion set to provide medication transmission therethrough and closes when the first syringe or infusion set is withdrawn. The second valved port is in communication with the second lumen and opens when connected with a second syringe or infusion set to provide fluid to inflate the balloon and closes when the second syringe or infusion set is withdrawn.
