Medicant Applicator Deformable Tip for Tablet Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for inserting misoprostol tablets into the vagina or rectum are cumbersome, prone to tablet breakage, and cause discomfort due to manual insertion, especially during emergency situations like postpartum hemorrhage, where rapid and precise administration is necessary.
Innovation Solution
A medicant applicator with a barrel, plunger, and deformable tip provides ergonomic features for comfortable and precise insertion, offering tactile and auditory feedback, and a secure locking mechanism to ensure accurate delivery of medicant tablets, suitable for vaginal and rectal administration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual insertion method is used, then the physician can directly insert tablets, but the insertion speed is slow and causes patient discomfort
Solution Approach 1:
The applicator device performs the insertion function automatically once loaded with tablets. The plunger mechanism self-advances to eject tablets through the deformable tip without requiring continuous manual manipulation, making the device serve itself to complete the insertion task efficiently.
Solution Approach 2:
The manual mechanical insertion by physician fingers is replaced with a controlled mechanical system consisting of a plunger and deformable tip. This mechanical substitution enables faster, more consistent tablet delivery while reducing the physical demands and discomfort associated with manual insertion.
2Quantity of substance
If multiple tablets are inserted rapidly, then the dosage requirement is met, but tablet breakage and dislodgement occur
Solution Approach 1:
The device loads multiple tablets in sequence within the barrel, allowing them to be administered one at a time through controlled plunger advancement. This segmentation prevents tablets from breaking or dislodging each other during insertion, as each tablet is ejected individually through the deformable tip rather than being forced simultaneously.
Solution Approach 2:
The tablets are pre-loaded into the barrel before insertion begins. This preliminary action allows the tablets to be positioned and secured in place before the actual insertion process, preventing breakage and dislodgement during the critical insertion phase when multiple tablets would otherwise be handled rapidly and precariously.
3Manufacturing precision
If deep insertion is required to reach posterior fornix, then proper medication placement is achieved, but patient discomfort increases
Solution Approach 1:
The deformable tip is designed with a curved, tapered shape that naturally follows the anatomical contours of the vaginal canal. This curvature allows the device to navigate the insertion path more smoothly and reach the posterior fornix with less resistance and patient discomfort compared to straight, rigid insertion tools.
Solution Approach 2:
The deformable tip is made from a flexible material that can compress and conform to the surrounding tissue during insertion. This flexibility reduces the mechanical stress and discomfort on the patient while still enabling the tip to reach the necessary depth for accurate medication placement at the posterior fornix.

AI summary
A medicant dispenser enabling the effective administration of tableted pharmaceutical products within a body cavity has a plunger, a barrel, and a deformable tip. The deformable tip provides a suitable leading element to allow the barrel to enter the body cavity, wherein the plunger may be pushed to eject the tableted pharmaceutical products into the body cavity through the deformable tip. More specifically, the deformable tip will comprise a plurality of cuspids fixed to a support ring, wherein the support ring is fitted to a terminal end of the barrel. The plurality of cuspids will collapse concentrically to form a tapered leading element of the medicant applicator while retaining the capacity to separate to allow passage of the tableted pharmaceutical products and a head of the plunger therethrough.
