Solution Overview
Problem
Traditional methods for implanting biosensors into the skin are slow, painful, and inaccurate, causing tissue damage and affecting detection efficacy due to the use of hard needles, which are difficult to position correctly and withdraw efficiently.
Innovation Solution
An auxiliary applicator with a launcher and needle returning component using torsion springs to rapidly penetrate and withdraw a guide needle, featuring a handle piece for controlled ejection and a drying box for the probe component, ensuring precise and pain-reduced implantation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If hard needles are used to implant biosensors, then the biosensor can be inserted into subcutaneous tissue, but the implantation speed is slow and the implantation position is inaccurate
Solution Approach 1:
The patent employs a spring-loaded launching mechanism that converts elastic potential energy into kinetic energy to rapidly propel the guide needle and biosensor into the subcutaneous tissue. This dynamic ejection system achieves both high implantation speed and precise positioning by controlling the launch parameters, resolving the contradiction between slow manual insertion and inaccurate positioning.
Solution Approach 2:
The patent introduces a guide needle as an intermediary component that facilitates the insertion of the biosensor. The guide needle is first ejected into the tissue to create a precise pathway, then the biosensor is advanced through this guide, ensuring accurate positioning while maintaining high speed. The guide needle acts as a mediator that enables both speed and precision.
2Ease of operation
If hard needles are used for implantation, then the biosensor can be inserted, but the withdrawal time is long causing user pain and tissue damage
Solution Approach 1:
The patent uses a spring-loaded mechanism to rapidly eject the guide needle and biosensor into the subcutaneous tissue. This dynamic insertion method reduces the time the needle remains in the tissue, minimizing pain and tissue damage while maintaining ease of operation through automated ejection.
Solution Approach 2:
The patent separates the guide needle from the biosensor, allowing the guide needle to be ejected first to create a pathway, then the biosensor to be advanced through it. This extraction of the guiding function from the sensing function enables faster withdrawal of the rigid guide needle while keeping the biosensor in place for continuous monitoring.
3Manufacturing precision
If manual insertion methods are used, then the device structure can be simple, but the implantation position is inaccurate and tissue damage occurs
Solution Approach 1:
The patent introduces a guide needle as an intermediary component that facilitates the insertion of the biosensor. The guide needle is first ejected into the tissue to create a precise pathway, then the biosensor is advanced through this guide, ensuring accurate positioning while maintaining high speed. The guide needle acts as a mediator that enables both speed and precision.
Solution Approach 2:
The patent divides the implantation system into separate components: a launcher for ejection, a guide needle for pathway creation, and the biosensor for monitoring. This segmentation allows each component to be optimized for its specific function, achieving accurate positioning without excessive overall device complexity.
