Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If vein visualization technology is used to improve injection accuracy, then visibility of vein is improved, but vein movement during operation makes it difficult to operate accurately
Solution Approach 1:
The compression strap is applied to the patient's arm before the near-infrared lamp is activated. This preliminary compression stabilizes the vein in position before visualization begins, preventing vein movement during the injection procedure. The binding means secures the compression strap to maintain consistent pressure throughout the procedure.
Solution Approach 2:
The invention combines multiple functions into a single integrated device: the compression strap provides mechanical stabilization, the near-infrared lamp provides visualization, and the controller coordinates their operation. This merging ensures that vein stabilization and visualization work together synergistically to solve both the visibility and movement problems simultaneously.
2Measurement precision
If near-infrared lamp is used to visualize vein, then vein position can be seen, but unskilled personnel still cannot perform injection safely
Solution Approach 1:
The controller receives feedback from the near-infrared camera about vein position and depth, then automatically adjusts the compression strap pressure and lamp illumination to maintain optimal visualization conditions throughout the injection procedure. This real-time feedback loop enables unskilled personnel to perform injections safely by relying on the system's automated adjustments.
Solution Approach 2:
The system performs self-adjustment of compression pressure and illumination intensity based on real-time vein visualization feedback, reducing the need for skilled operator judgment. The device automatically optimizes its own parameters to maintain safe and effective injection conditions throughout the procedure.
3Stability of the object's composition
If compression strap is applied to stabilize vein, then vein movement is prevented, but additional device components increase system complexity
Solution Approach 1:
The compression strap serves multiple functions: it stabilizes the vein in position, provides a mounting surface for the near-infrared lamp, and acts as a barrier to prevent direct skin contact with the lamp. The binding means also serves dual purposes of securing the strap and positioning the lamp. This multi-functionality reduces the need for separate components, thereby reducing overall system complexity while maintaining vein stabilization.

AI summary
The present invention relates to the intravenous injection aid for indicating vein, comprising: a compression strap; a binding means disposed at the opposite ends of the compression strap; a near-infrared lamp disposed at the compression strap; and a controller disposed on the compression strap for controlling the near-infrared lamp. The present invention as mentioned above may not only indicates vein with high visibility but also keep the vein from swaying or moving even during intravenous injection, so the intravenous injection can be carried out safely and efficiently.
