Self-Disinfecting Vial Cap With Rupturable Antiseptic Pouch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medication vial caps do not ensure sterile conditions when inserting or removing a syringe needle, potentially leading to contamination and infection risks.
Innovation Solution
A self-disinfecting medication vial cap assembly with a rupturable antiseptic pouch that releases antiseptic upon opening, ensuring the cap and needle insertion site are disinfected before use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional medication vial cap is used, then the device structure remains simple, but sterile conditions cannot be ensured during needle insertion and removal
Solution Approach 1:
The antiseptic pouch is pre-loaded and sealed within the cap assembly before use. When the cap is opened, the pouch automatically ruptures and applies antiseptic to the needle insertion site in advance, ensuring sterile conditions before the needle contacts the medication
Solution Approach 2:
The antiseptic pouch is nested inside the cap assembly, with the pouch contained within the cap's internal cavity. This nested structure allows the complex disinfection mechanism to be integrated within the simple external appearance of the cap
2Reliability
If antiseptic is applied manually before needle insertion, then sterile conditions can be partially achieved, but the process requires additional steps and time
Solution Approach 1:
The cap assembly performs self-disinfection automatically when opened. The mechanical action of opening the cap triggers the pouch to rupture and apply antiseptic without requiring the user to manually apply antiseptic, making the sterilization process as simple as opening the cap
3Reliability
If the cap remains closed to maintain sterility, then contamination is prevented, but the needle cannot be inserted for medication access
Solution Approach 1:
The antiseptic is applied to the insertion site in advance of needle contact, during the cap opening process itself. This preliminary disinfection ensures that when the needle is inserted immediately after opening, the sterile field is already established, enabling rapid medication access
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 solution provides a sterile environment for needle insertion and removal, reducing the risk of contamination and infection by effectively disinfecting the cap and needle insertion site with the released antiseptic.
Implementation Method 1
The pouch membrane may be ruptured upon opening of the assembly cap, releasing the antiseptic from the pouch onto the assembly base to disinfect the assembly base

AI summary
A self-disinfecting medication vial cap assembly for a medication vial includes a needle-penetrable assembly base configured for attachment to the medication vial; an assembly cap carried by the assembly base, the assembly base and the assembly cap having a cap interior and the assembly cap positional between closed and open positions; a rupturable antiseptic pouch attached to the assembly base and the assembly cap in the cap interior; and an antiseptic contained in the antiseptic pouch. The antiseptic pouch remains intact in the closed position of the assembly cap. The antiseptic pouch ruptures and the antiseptic is discharged onto the assembly base upon movement of the assembly cap from the closed position to the open position.
