Solution Overview
Problem
Current medical injection procedures face challenges due to user anxiety and lack of experience, leading to errors in administering injections, particularly with self-injection devices that require needle use, which can result in incomplete doses and safety risks.
Innovation Solution
An injection simulation device that mimics the look and feel of a needle-containing injection device, providing tactile, visual, and auditory feedback to simulate the forces encountered during an injection, such as deformation, puncture, and insertion forces, to help users practice and become familiar with the injection process without actual needle penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a real needle-containing injection device is used for training, then the training is more realistic and effective, but it causes anxiety, fear, and safety risks to users
Solution Approach 1:
The patent creates a simulation device that copies the essential features and tactile feedback of a real injection device without using actual needles. The simulation member replicates the mechanical sensations of needle insertion, deformation, puncture, and insertion forces, providing realistic training experience while eliminating the harmful effects of actual needle penetration.
Solution Approach 2:
The simulation device acts as an intermediary between the training objective and the real injection procedure. It provides a safe intermediate step that bridges the gap between theoretical knowledge and actual practice, allowing users to familiarize themselves with the injection process without direct exposure to needles.
2Ease of operation
If users perform self-injection without proper training, then they can administer medications independently, but errors and safety risks increase
Solution Approach 1:
The simulation device enables preliminary practice and skill development before actual injection administration. Users can repeatedly practice proper technique, dosing mechanism operation, and force application in a safe environment, building confidence and competence prior to independent medication administration.
Solution Approach 2:
The device provides tactile feedback that mirrors the actual injection process, including resistance during skin deformation, the sensation of puncture, and insertion forces. This feedback mechanism allows users to adjust their technique in real-time based on the simulated response, improving injection accuracy and safety.
3Object-affected harmful factors
If a simulation device without tactile feedback is used, then the device is simpler and safer, but it cannot provide realistic training experience
Solution Approach 1:
The patent replaces the actual mechanical needle-tissue interaction with a simulated mechanical system. The simulation member, when actuated, replicates the sequence of mechanical events during injection (deformation, puncture, insertion) through controlled movement and force application, providing tactile feedback without the biological complexity and risks of real tissue penetration.

Implementation Method 1
at least one first biasing member, wherein the at least one first biasing member is associated with the retractable injection simulation member, and directly or indirectly associated with the plunger, wherein a first force on a distal end of the injection simulation member causes movement of the injection simulation member from an extended position to a retracted position, to compress the first biasing member
Implementation Method 2
a second force on the proximal end of the plunger asserts a third force directly or indirectly on the first biasing member to facilitate resetting the injection simulation member to the extended position
