Percutaneous Access Template for Chest Decompression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical devices for procedures like chest decompression rely on users identifying anatomical landmarks, which is challenging for untrained personnel, especially in stressful environments, leading to high failure rates and incorrect placements.
Innovation Solution
A percutaneous access template device that aligns with anatomical landmarks, providing a safe zone for accurate needle or tube insertion, designed for use by both skilled and unskilled personnel, with features like axilla and iliac crest pointers to simplify the procedure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If anatomical landmarks are used for procedure localization, then the procedure can be performed by untrained personnel, but the accuracy and reliability of landmark identification deteriorates under stress
Solution Approach 1:
The patent introduces a template device as an intermediary tool between the untrained operator and the anatomical landmarks. The template provides pre-marked guidance lines and target zones that mediate the localization process, allowing untrained personnel to achieve accurate needle placement without needing to independently identify complex anatomical landmarks under stress
Solution Approach 2:
The template is pre-prepared with marked anatomical landmarks, guidance lines, and target zones before the procedure. This preliminary action transfers the complexity of landmark identification from the stressed operator to the pre-designed template, enabling accurate procedure localization even when the operator is untrained or under duress
2Productivity
If traditional needle decompression procedure is used, then the procedure can be performed quickly, but the failure rate and incorrect placement rate increase
Solution Approach 1:
The template is pre-prepared with all necessary guidance information including landmark positions, needle insertion paths, and target zone markings. This allows the operator to quickly apply the template and perform the procedure without spending time on complex anatomical analysis, thereby maintaining speed while improving accuracy and success rate
Solution Approach 2:
The patent replaces the reliance on operator skill and anatomical knowledge (human mechanical system) with a standardized template device that provides objective guidance. This substitution reduces variability in procedure outcomes and increases reliability while maintaining operational efficiency

AI summary
A device (100) for medical procedure localization that provides a template that indexes the site of interest along a first axis or plane that is defined by anatomical landmarks of a patient. An embodiment is disclosed in which a first axis is an axillary line from the patient's axilla (armpit) toward the iliac crest (pelvis) and the site of interest is a distance away from the axilla along said first axis. The site of interest is the 3rd, 4th or 5th intercostal space, into which a needle/catheter and/or chest tube may be placed for decompression.
