Antibacterial Suture Packaging with On-Demand Antimicrobial Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suture packaging solutions fail to effectively prevent post-surgical infections while maintaining a sufficient shelf life, as antimicrobial materials absorbed by the suture reduce its longevity.
Innovation Solution
A suture packaging kit design that separates the suture and antimicrobial material, using a sealed accommodation unit with a partition and antimicrobial capsule, allowing the antimicrobial material to be absorbed by the suture through a simple pressing operation just before use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antimicrobial material is absorbed by the suture during storage, then infection prevention is improved, but shelf life is reduced
Solution Approach 1:
The packaging kit is divided into separate compartments: a first accommodation unit for the suture and a second accommodation unit for the antimicrobial material. This segmentation prevents premature contact between the suture and antimicrobial material, preserving shelf life while enabling infection prevention when needed.
Solution Approach 2:
The antimicrobial material is extracted from direct contact with the suture during storage and placed in a separate compartment. It can be applied to the suture just before use through a simple pressing operation, ensuring infection prevention without compromising shelf life.
2Reliability
If antimicrobial material is included in the package, then infection prevention is improved, but the suture absorbs the material during storage reducing shelf life
Solution Approach 1:
The packaging kit is prepared in advance with the suture and antimicrobial material separately positioned in their respective compartments. The design includes a mechanism that enables easy activation just before use, combining the benefits of pre-preparation with on-demand antimicrobial application.
Solution Approach 2:
A partition or barrier structure acts as an intermediary between the suture and antimicrobial material during storage, preventing direct contact while maintaining the ability to easily activate the antimicrobial function when needed.
3Ease of operation
If the package is opened before surgery, then accessibility is improved, but bacteria or germs may enter and contaminate the suture
Solution Approach 1:
The packaging is segmented into separate sealed compartments that can be opened independently or simultaneously. This allows the suture to remain protected in its compartment while the antimicrobial material compartment is accessed, maintaining sterility while providing accessibility.
Solution Approach 2:
The packaging design enables the user to activate the antimicrobial function by simply pressing a mechanism, allowing the antimicrobial material to be dispensed onto the suture without requiring full package opening or complex procedures, maintaining sterility while ensuring ease of use.
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
This design effectively suppresses surgical site infections by ensuring the antimicrobial material is absorbed by the suture just before use, extending shelf life and providing convenience and hygiene.
Implementation Method 1
an antimicrobial capsule 190 which is accommodated in the second accommodation unit 150 and is filled with the antimicrobial material 170 to be swelled by the antimicrobial material 170
Implementation Method 2
the antimicrobial material 170 passes through a movement path formed by the partition 300 when the second accommodation unit 150 is pressed to rupture the antimicrobial capsule 190, and then flows into the suture kit 130
Implementation Method 3
flows into the suture kit 130, to be absorbed by the suture 120

AI summary
An antimicrobial suture package kit of the present disclosure includes a first accommodation unit 140 which has an internal space sealed by a bonded portion 110 formed by welding two synthetic resin sheets; a suture kit 130 accommodated in the first accommodation unit 140; a second accommodation unit 150 which is located to be adjacent to the first accommodation unit 140 and has an internal space sealed by the bonded portion 110; a liquid antimicrobial material 170 accommodated in the second accommodation unit 150; a partition 300 which partially partitions the first accommodation unit 140 and the second accommodation unit 150 so as to ensure a movement path of the antimicrobial material 170; and an antimicrobial capsule 190 which is accommodated in the second accommodation unit 150 and is filled with the antimicrobial material 170 to be swelled by the antimicrobial material 170, and the antimicrobial material 170 is filled in the antimicrobial capsule 190 to be accommodated separately from the suture kit 130 and passes through a movement path formed by the partition 300 when the second accommodation unit 150 is pressed to rupture the antimicrobial capsule 190, and then flows into the suture kit 130, to be absorbed by the suture 120.
