Subcutaneous Vein Access Port with Light Source
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing subcutaneous vein access ports are difficult to locate after implantation, making it challenging for unskilled individuals to accurately and safely inject medicine due to the hidden chamber and small cover membrane.
Innovation Solution
Incorporation of a light source within the access port that emits light through the cover membrane, allowing for easy identification of the chamber's location, powered by a substrate and switch mechanism, and optionally activated by an external signal or chemiluminescent material for simple operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If the chamber is sealed with a self-sealing cover membrane and implanted into the human body, then the device provides long-term medicine administration capability, but the chamber becomes hidden and difficult to locate with the naked eye
Solution Approach 1:
The patent applies a light-emitting element that emits light through the cover membrane, creating a visible light signal that indicates the location of the implanted chamber. This resolves the contradiction by making the hidden chamber detectable without compromising its sealed, long-term functionality.
Solution Approach 2:
The patent introduces light as an intermediary signal between the implanted chamber and the external environment. The light-emitting element acts as a mediator that translates the internal chamber location into an externally visible signal, allowing easy location identification while maintaining the chamber's sealed state.
2Area of stationary object
If the cover membrane is made small to maintain a compact implantable device, then the device size is reduced, but the area available for needle insertion becomes too small for accurate and safe insertion by unskilled persons
Solution Approach 1:
The light-emitting element creates a visible light signal through the cover membrane that marks the exact insertion point. This allows unskilled persons to accurately locate and insert the needle into the small cover membrane area, resolving the contradiction between compact size and ease of operation.
Solution Approach 2:
Light serves as an intermediary visual guide that bridges the gap between the small cover membrane and the user's ability to accurately locate it. The light signal acts as a mediator that enhances the usability of the compact device without requiring larger membrane area.
3Device complexity
If no visual indicator is provided on the implanted chamber, then the device structure remains simple, but an operator cannot easily identify the exact location of the chamber for medicine injection
Solution Approach 1:
The light-emitting element provides a simple yet effective visual indicator by emitting light through the cover membrane. This adds minimal structural complexity while dramatically improving chamber location detection, resolving the contradiction between simplicity and detectability.
Solution Approach 2:
The patent replaces the need for complex mechanical or structural visual indicators with a simple light-emitting mechanism. This substitution achieves effective location identification with minimal added complexity, resolving the contradiction between device simplicity and detection ease.

AI summary
A subcutaneous vein access port implanted into a living body to be connected to a subcutaneous vein, includes: a housing formed therein with a receiving portion to which a medicine is supplied; a cover membrane disposed at an upper end of the housing and sealing an upper side of the receiving portion; a conduit provided to the housing and inserted into the subcutaneous vein to connect the subcutaneous vein to the receiving portion; and a light source emitting light such that the light from the light source is discharged outside through the cover membrane.
