Painless Piercing Conduit with One-Way Valve and Middle Aperture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing piercing conduits for painless medication delivery fail to effectively incorporate a top distal end with a one-way valve and a pointed bottom distal end, both exposed outside the skin, along with a middle aperture for needle insertion, which are essential for efficient and economical medication delivery.
Innovation Solution
A piercing conduit with a top distal end featuring a one-way valve and an impermeable seal, a middle aperture for needle insertion, and a pointed bottom distal end made of surgical steel or titanium, allowing for painless medication delivery by inserting the needle through the skin and injecting medication through the middle aperture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a piercing conduit uses a traditional needle design with pointed distal ends left outside the skin, then the device structure is simple, but the medication delivery causes pain and requires frequent needle changes
Solution Approach 1:
The piercing conduit is divided into multiple segments: a reusable piercing conduit body with a middle aperture that remains inside the skin, and disposable needles that can be inserted and removed. This segmentation allows the painless middle aperture to remain in place while only the needle portion is replaced, reducing pain and improving ease of manufacture.
Solution Approach 2:
The middle aperture of the piercing conduit acts as an intermediary structure that remains embedded in the skin, allowing needle insertion without requiring a new puncture each time. This intermediary element mediates between the disposable needle and the skin, enabling painless repeated medication delivery.
2Reliability
If a piercing conduit includes a top distal end with one-way valve and impermeable seal, then medication delivery reliability is improved, but device complexity increases
Solution Approach 1:
The one-way valve and impermeable seal are applied locally at the top distal end of the piercing conduit, specifically at the medication delivery site. This localized application improves medication delivery reliability without requiring the entire conduit structure to be complex, as only specific regions have enhanced features.
3Ease of operation
If a piercing conduit has both top and bottom distal ends exposed outside the skin with middle aperture inside, then self-administration accessibility is improved, but manufacturing precision requirements increase
Solution Approach 1:
The piercing conduit is pre-configured during manufacturing with the middle aperture positioned at the optimal location for needle insertion and medication delivery. This preliminary positioning action ensures that during self-administration, the user simply needs to insert the needle into the pre-positioned aperture without requiring precise positioning skills, thus improving ease of operation while managing manufacturing precision requirements.

Function Achieved in This Case
Enables self-administration of medication in a painless and cost-effective manner, suitable for users requiring constant medication, such as diabetes or dialysis patients, by maintaining the needle and syringe outside the skin while the middle aperture remains inside for efficient fluid delivery.

AI summary
A piercing conduit to deliver medications to a user in a painless method including a placement phase, an inserting phase and an injection phase which are performed by the piercing conduit. The placement phase includes a penetrating bottom distal end of the piercing conduit which is inserted through a user's skin of the abdomen portion to place a middle aperture in the inside of the user's skin and then leave exposed the penetrating bottom distal end and a top distal end. The inserting phase passes through a sealing cap from the top distal end which has an aperture in which a needle is inserted along a conduit portion and then reaches the middle aperture that is placed inside of the user's skin. The injection phase delivers the medication with the syringe by the needle allowing to apply medication in a painless method. The piercing conduit is configured to be applied to users with constant medication such as diabetes or dialysis.
