Transparent Vascular Access Trainer for Ultrasound Insertion Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional venipuncture training models lack sufficient feedback for clinicians to visualize the insertion of medical devices under the skin, especially with ultrasound guidance, leading to difficulties in improving insertion skills and ensuring proper placement of needles and guidewires or catheters.
Innovation Solution
A transparent anatomical training model with clinically relevant ultrasonic properties, allowing unaided visualization of simulated vasculature and providing video recording of the procedure to enhance feedback and improve technique.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional venipuncture training models are used, then clinicians can practice needle insertion, but they cannot visualize what is occurring under the skin with the needle during venipuncture
Solution Approach 1:
The training model uses transparent or translucent materials for the skin and subcutaneous tissue layers, allowing light to pass through and enabling visualization of the needle, blood vessel, and internal structures. This transparency provides real-time visual feedback to clinicians during the insertion procedure without requiring additional imaging equipment.
Solution Approach 2:
The training model creates a simplified copy of human anatomy with transparent layers that replicate the structural relationships of skin, subcutaneous tissue, and blood vessels. This anatomical copy allows clinicians to practice insertion techniques while visualizing the procedure, bridging the gap between simple models and complex real anatomy.
2Reliability
If conventional venipuncture training models are used, then clinicians can practice insertion techniques, but they do not receive sufficient feedback to improve their ultrasound and insertion skills
Solution Approach 1:
The transparent design of the training model provides immediate visual feedback to clinicians during the insertion procedure. Clinicians can directly observe the needle's path, depth, and positioning relative to the blood vessel, allowing them to adjust their technique in real-time and understand what constitutes proper insertion form and technique.
Solution Approach 2:
The training model adds the dimension of visual transparency to the traditional opaque training model, enabling clinicians to observe the three-dimensional spatial relationships and depth of insertion structures that are normally hidden beneath the skin surface.
3Measurement precision
If multiple puncture attempts are made on patients, then clinicians can locate the intended blood vessel, but excess trauma is caused to the patient
Solution Approach 1:
The training model allows clinicians to practice and perfect their vessel location and insertion skills before performing procedures on patients. By repeatedly practicing on the transparent model with immediate visual feedback, clinicians develop the precision needed to locate vessels accurately on the first attempt, thereby reducing the need for multiple puncture attempts on actual patients.
Solution Approach 2:
The transparent training model serves its own educational purpose by providing built-in visual feedback without requiring external imaging equipment. The model's design inherently demonstrates proper technique and vessel location, allowing clinicians to self-correct and improve their skills through repeated practice.

Function Achieved in This Case
The model enables clinicians to visualize and record needle and catheter insertion procedures, offering definitive feedback for skill improvement and ensuring proper placement, thus reducing the need for multiple puncture attempts and patient trauma.
Implementation Method 1

AI summary
A vascular access training simulator system for training intravascular insertion of a medical device is disclosed. The vascular access training simulator system includes an anatomical training model having clinically relevant ultrasonic properties representative of ultrasonic properties of a human body site for ultrasound imaging. The training model includes a transparent housing, a transparent simulated tissue, at least one simulated blood vessel suspended in the tissue, and a layer of simulated skin covering the housing and the tissue. A first imaging device is records a first video showing a view of an insertion site outside of the simulated skin. A second imaging device records a second video showing the simulated blood vessel through the transparent simulated tissue. A third imaging device is shows an ultrasound view of the simulated blood vessel and the simulated tissue. A monitor displays a composite view of all three videos simultaneously on a single screen.
