Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical training devices for injections lack hands-on simulation, leading to anxiety and inefficiency in administering injections, especially for self-administration and inexperienced users, as they fail to accurately replicate the forces and sensations involved in needle insertion.
Innovation Solution
An injection simulation device with a retractable injection simulation member that mimics the forces of needle insertion, including deformation, puncture, and insertion forces, using a resistance mechanism to simulate the experience of injecting without actual skin penetration, providing tactile, visual, and auditory feedback to mimic the actual injection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional injection training methods are used, then users can learn injection procedures, but anxiety and fear remain high due to lack of realistic simulation
Solution Approach 1:
The patent creates a realistic copy of the injection experience using a simulation device that replicates the physical sensations of needle insertion through resistance mechanisms. The simulation member mimics tissue resistance and needle penetration forces, providing tactile feedback that closely resembles actual injection without causing harm, thereby reducing anxiety while maintaining training effectiveness.
2Manufacturing precision
If no simulation device is used, then device complexity is low, but injection accuracy and compliance are poor
Solution Approach 1:
The patent employs resistance mechanisms with adjustable parameters that can be modified to simulate different tissue types and injection conditions. By changing resistance values and mechanical properties of the simulation member, the device can replicate various injection scenarios, improving training accuracy without requiring an overly complex device architecture.
3Ease of operation
If self-injection is practiced without proper training simulation, then patients gain independence, but errors and improper administration increase
Solution Approach 1:
The patent enables patients to perform preliminary practice injections using the simulation device before actual self-injection. The device allows repeated practice of the injection motion and force application in a safe environment, building muscle memory and confidence, thereby improving both independence and accuracy when transitioning to real self-injection.

AI summary
An injection simulation device for simulating one or more forces of an injection is provided herein. The device may include a housing and a retractable injection simulation member associated with the housing, wherein the retractable injection simulation member retracts according to a multi -phase force profile. The multi-phase force profile includes a first phase configured to simulate a deformation force of pressing a needle against a subject so as to deform at least a first layer of tissue prior to traversing at least the first layer of tissue of the subject, a second phase configured to simulate a puncture rebound force, and a third phase configured to simulate an insertion force.
