Modular Injection Training Pad Simulating Tissue Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current injection training devices are often costly and fail to effectively simulate various types of injections, such as intradermal, subcutaneous, and intramuscular, due to the expense of materials and manufacturing complexities.
Innovation Solution
A modular injection training pad with a container, lid, retaining member, cushion, and cap designed to simulate skin and muscle tissue, allowing for practice of different injection types with a durable, nonporous structure and flexible cap to mimic human skin, providing a realistic simulation of needle insertion and fluid injection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If life-like training pads or mannequins are used to simulate skin and muscle tissue, then the realism of injection simulation is improved, but the manufacturing cost and material expense increase significantly
Solution Approach 1:
The training device is divided into separate functional layers: a cap simulating skin tissue, a cushion simulating muscle tissue, and a container for fluid storage. Each layer can be manufactured independently using simple, inexpensive materials and then assembled together to create the complete training device.
Solution Approach 2:
The patent employs inexpensive materials such as foam for the cushion and simple plastic or rubber for the cap and container. These components are designed to be cost-effective and can be easily replaced if needed, avoiding the high costs associated with durable life-like mannequins while maintaining training effectiveness.
2Adaptability or versatility
If a single training device is designed to accommodate multiple injection types (intradermal, subcutaneous, intramuscular), then the versatility of the device is improved, but the device complexity increases
Solution Approach 1:
The training device is designed with a universal structure where the layered composition (cap, cushion, container) can accommodate all three main injection types. The varying depths and angles of needle insertion naturally access different layers, allowing the same device to train intradermal, subcutaneous, and intramuscular injection techniques without requiring separate specialized devices.
Solution Approach 2:
The device incorporates a flexible cushion layer that can be compressed during injection, allowing dynamic adjustment to different injection depths and pressures. This flexibility enables the same static structure to adapt to multiple injection techniques without requiring complex mechanical adjustments.

AI summary
Disclosed is an injection training pad that allows a user to practice intradermal, subcutaneous and intramuscular injections all on the same device. The injection training pad includes a container having an open top and a closed bottom. A lid having a hole removably engages the open top of the container. The pad also includes a retaining member having a base with at least one leg. At least a portion of the retaining member is disposed within the container. A cap having a flange is positioned between the retaining member and the lid, and a cushion is positioned between the retaining member and the cap.
