Intraosseous Infusion Trainer with Modular Bone Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current trauma-care training tools lack realistic simulation of intraosseous infusion procedures, making it difficult for trainees to develop the necessary skills to successfully perform the procedure, especially in scenarios where intravenous access is not available.
Innovation Solution
A trainer device comprising a mannequin with a simulated injection site that includes a pocket, an insert simulating a hard bone exterior, and an outer cover simulating skin, allowing for realistic practice of intraosseous infusion while minimizing leakage and simplifying cleanup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a realistic intraosseous infusion trainer is developed, then training effectiveness is improved, but device complexity increases
Solution Approach 1:
The trainer is divided into separate modular components: a mannequin body, a removable injection-site simulant, and a bone insert. This segmentation allows each component to be optimized independently while maintaining overall realism for training purposes.
Solution Approach 2:
The injection-site simulant creates a realistic copy of the intraosseous infusion site using tactile materials that replicate the feel of skin, fat, and bone. The bone insert simulates the hard exterior and marrow cavity, providing authentic training feedback without requiring actual anatomical structures.
2Object-generated harmful factors
If fluid containment is improved to minimize leakage, then cleanup simplicity is improved, but device complexity increases
Solution Approach 1:
The bone insert is nested within the injection-site simulant, which is itself nested within the mannequin body. This nested structure creates multiple containment layers that work together to prevent fluid leakage while maintaining a clean and simple external appearance.
Solution Approach 2:
The bone insert acts as an intermediary barrier between the fluid injection site and the external environment. It provides a sealed cavity that contains fluids while allowing the training procedure to be performed, thereby preventing leakage without requiring complex external containment systems.
3Ease of repair
If the trainer allows component replacement after use, then ease of repair is improved, but device complexity increases
Solution Approach 1:
The trainer is designed with separable modules including a removable injection-site simulant and a replaceable bone insert. This segmentation enables easy replacement of worn or damaged components without affecting the entire system, simplifying maintenance while requiring a modular design architecture.
Solution Approach 2:
The bone insert and injection-site simulant are designed as disposable or replaceable components that can be easily removed and replaced after use. This approach prioritizes ease of repair and component replacement over permanent durability, allowing training systems to be maintained through simple component swapping rather than complex repairs.

AI summary
A trainer for practicing an intraosseous infusion is presented. The trainer includes a mannequin and an injection-site simulant. The mannequin is in the form of a body, either human or animal, in part or whole. The injection-site simulant further includes a pocket, an insert, and an outer cover. The pocket extends into the mannequin. The insert simulates a hard exterior of a bone and is disposed within the pocket. The outer cover with a plug simulates a skin, either human or animal. The outer cover conceals the insert, pocket, and plug. The pocket and insert cooperate to form a cavity where marrow resides within the bone. The cavity is capable of receiving a fluid injected through a hole formed during use through the outer cover, plug, and insert. The plug sealingly contacts and cooperates with the insert and/or the wall within the pocket to confine the fluid within the cavity.
