Rocket-Shaped Rectal Suppository for Hemorrhoid Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rectal suppositories for hemorrhoids are prone to slippage and fail to effectively retain medication at the hemorrhoid site, particularly for external hemorrhoids, due to their pill or bullet shapes, leading to reduced efficacy.
Innovation Solution
A rocket-shaped rectal suppository with a small tip for easy insertion and a wider base to prevent slippage, featuring a longitudinal slit-like cavity for gas release, which retains medication at the hemorrhoid site and slowly delivers it through slow dissolution, treating both internal and external hemorrhoids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pill-shaped rectal suppository is used for easy insertion, then insertion ease is improved, but the suppository slips out of the rectum and fails to retain medication at the hemorrhoid site
Solution Approach 1:
The suppository is designed with an asymmetric rocket shape featuring a tapered tip for insertion and a flared base for retention. The base diameter is significantly larger than the tip diameter, creating an asymmetric geometry that allows easy insertion through the narrow anal opening while preventing slippage outward, as the flared base cannot pass back through the narrow sphincter.
Solution Approach 2:
The invention transitions from a traditional cylindrical pill shape to a three-dimensional rocket shape with varying cross-sectional dimensions along its length. The suppository has a small tip dimension for insertion, a middle section for positioning, and a wide base dimension for anchoring, utilizing dimensional variation to simultaneously achieve easy insertion and secure retention.
2Ease of operation
If a bullet-shaped suppository is used, then insertion is facilitated, but the suppository travels too far inside the rectum and cannot treat external hemorrhoids
Solution Approach 1:
The rocket-shaped suppository employs asymmetric geometry with a flared base that rests against the anal sphincter and lower rectum, positioning the medication delivery surface at the optimal location for treating both internal and external hemorrhoids. This asymmetric design prevents the suppository from traveling too far into the rectum while still allowing easy insertion.
Solution Approach 2:
The suppository is designed with different functional zones: the tip for insertion, the middle section for positioning, and the flared base for retention and localized medication delivery. The medication is formulated to dissolve and deliver active ingredients locally at the hemorrhoid site, with the flared base ensuring direct contact with both internal and external hemorrhoid regions.
3Ease of manufacture
If conventional pill-shaped suppositories are used, then manufacturing is simple, but slippage occurs reducing treatment efficacy
Solution Approach 1:
The rocket shape with its flared base and tapered tip can be manufactured using standard mold-making techniques. The asymmetric geometry is created by designing molds with the desired rocket profile, allowing the suppository to be formed in a single molding process while maintaining manufacturing efficiency and consistency.
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 rocket-shaped design effectively keeps the medication at the hemorrhoid site, enhancing treatment efficacy by preventing slippage and ensuring direct delivery of medication to both internal and external hemorrhoids, improving pain relief and inflammation management.
Implementation Method 1
Upon insertion into the rectum, the rocket-shaped suppository slowly dissolves inside the body and delivers the medication to treat internal and external hemorrhoids simultaneously.
