Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The detection of the connection terminal of an implanted ultrasound device is difficult due to factors such as edema and thick scalp, leading to prolonged connection times and patient discomfort.
Innovation Solution
An implantable medical device with a positioning indicator, comprising light-emitting diodes or resonant passive electrical circuits, facilitates the detection of the connection terminal by emitting light radiation or inducing electromagnetic interference, allowing precise localization using a location unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If palpation through the patient's scalp is used to detect the connection terminal, then the detection method is simple, but the detection time increases and patient discomfort increases due to edema and thick scalp
Solution Approach 1:
A positioning indicator comprising light-emitting diodes is introduced as an intermediary element between the connection terminal and the detection system. The LEDs are positioned around the connection terminal and emit light that can be detected through the scalp, serving as a mediator that enables indirect detection of the terminal position without requiring direct palpation.
Solution Approach 2:
The mechanical palpation method is replaced with an optical detection system. Instead of using tactile sensation to locate the connection terminal, the invention uses light-emitting diodes that emit optical signals detectable through the scalp, substituting a mechanical sensing approach with an optical one.
2Measurement precision
If multiple needle insertion attempts are made to locate the connection terminal, then the detection accuracy improves, but patient discomfort increases
Solution Approach 1:
The positioning indicator with light-emitting diodes is activated before the needle insertion procedure begins. This preliminary action provides advance information about the precise location of the connection terminal, allowing the operator to plan and execute a single accurate insertion rather than multiple attempts.
Solution Approach 2:
The light-emitting diodes serve as an intermediary that provides visual guidance for needle insertion. The optical signals emitted by the LEDs guide the operator to the exact terminal position, eliminating the need for multiple exploratory insertion attempts.
3Reliability
If the connection terminal is deeply embedded due to thick scalp and edema, then the implantation is secure, but the detection and connection time increases
Solution Approach 1:
The light-emitting diodes act as an intermediary signaling system that penetrates or transmits through the thick scalp and edematous tissue. The optical signals from the LEDs can be detected despite the tissue barriers, providing a reliable method to locate the terminal position without requiring shallow placement.
Solution Approach 2:
The light-emitting diodes emit visible light that can be detected through the scalp tissue. The optical signals provide a visual indicator that remains detectable regardless of the depth of the terminal embedding, allowing rapid location even through thick or edematous tissue.
