Portable Rib Panel Trainer for Chest Tube and Pericardiocentesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical professionals lack access to affordable and portable simulators for training in rare procedures like chest tube insertion and pericardiocentesis, leading to procedural skill decay due to limited access to simulation centers.
Innovation Solution
A portable, easy-to-assemble simulator apparatus comprising a base and rib panel that simulates the human rib cage, allowing practitioners to practice chest tube insertion and pericardiocentesis in various locations using off-the-shelf materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current trainers are used for procedural training, then training fidelity is maintained, but cost and complexity increase making them inaccessible to most practitioners
Solution Approach 1:
The simulator is divided into separate modular components including a rib cage assembly, base, and optional overlay layers. Each module can be independently assembled and configured, allowing practitioners to build a functional trainer without requiring a complex integrated system. The rib cage portion can be separated from the base for storage or transport.
Solution Approach 2:
The simulator creates a simplified copy of the actual anatomical structure using readily available materials. The rib cage is constructed to replicate the essential geometry and insertion mechanics of human ribs without requiring expensive proprietary materials. This allows faithful procedural training through approximation rather than exact replication.
2Reliability
If simulation centers are accessed for training, then procedural skill maintenance is achieved, but accessibility and cost decrease
Solution Approach 1:
The simulator is designed as a self-contained system that practitioners can assemble and use independently without requiring access to a centralized simulation center. All necessary components are included in a single kit that can be stored and used in any clinical setting, eliminating the need for external facilities or staffed training centers.
Solution Approach 2:
The simulator is designed to be universally applicable across different clinical settings and procedures. The same basic apparatus can be used for training various chest access procedures including tube thoracostomy, pericardiocentesis, and other needle insertion techniques, making it adaptable to diverse training needs without requiring multiple specialized systems.
3Reliability
If expensive simulation equipment is purchased, then training quality improves, but affordability and portability decrease
Solution Approach 1:
The simulator components are designed to be separable and compact when disassembled. The rib cage portion can be detached from the base and stored in a compact form, making the entire system portable and easy to transport between clinical locations or store in limited space without requiring a large dedicated training room.
4Strength
If complex assembly is required for the simulator, then structural integrity is improved, but ease of assembly decreases
Solution Approach 1:
The connector pieces serve dual functions by simultaneously providing structural reinforcement at joint locations and acting as simple snap-fit or friction-based fasteners. This integration of structural and fastening functions into single components maintains base integrity while eliminating the need for separate complex assembly mechanisms.

AI summary
A simulator apparatus for training medical professionals in the procedures of chest tube insertion and/or pericardiocentesis. The apparatus includes a first stand element and a second stand element that form a rib panel base with the two elements substantially at right angles to one another to create a 90-degree stand. A rib panel is removably joined to the two stand elements and includes curved slots representing the spaces between ribs. This allows for the insertion of chest tubes between the simulated rib spaces, using off-the-shelf supplies to create a subcutaneous and skin overlay. For training in pericardiocentesis, the rib panel can be placed on a standard dimension medical basin, which is filled with a training heart with a pericardial effusion created with off-the-shelf supplies. The basin is then filled with echogenic material (water, water and fiber supplement, or gelatin) that facilitates ultrasound.
