Drug Injector with Nested Imaging for Precise Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drug injecting implements with sliding attachment units lack precision in injecting drug solutions due to the inability to accurately indicate the needle insertion position in the human body, leading to potential wastage of expensive drugs and reduced efficacy, and require specific drug containers that can be inconvenient to use.
Innovation Solution
A drug injecting implement equipped with an image measuring unit that captures images inside the body to precisely adjust the needle position, combined with a sliding attachment unit that allows for the use of universal drug containers or cartridges, enabling accurate drug delivery and flexible dosing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional sliding attachment unit is used without an image measuring unit, then the device structure remains simple, but the injection position accuracy deteriorates
Solution Approach 1:
The image measuring unit is nested within the insertion needle structure, allowing the needle and imaging components to be inserted together as a single integrated unit into the human body, thereby achieving precise positioning without significantly increasing external device complexity
Solution Approach 2:
The image measuring unit acts as an intermediary between the insertion needle and the practitioner, providing visual feedback about the needle's position inside the body, which enables accurate positioning without requiring the practitioner to directly sense or guess the injection site
2Ease of operation
If a separate drug container is used for each injection, then the drug dose can be precisely controlled, but the operation convenience deteriorates
Solution Approach 1:
The sliding attachment unit is designed with a universal interface that can accommodate different sizes and types of drug containers, allowing a single injection device to work with multiple container configurations, thereby improving operation convenience while maintaining dosing flexibility
Solution Approach 2:
The sliding attachment unit can be dynamically adjusted along the longitudinal axis of the main body, allowing the practitioner to position the drug container at different locations depending on the required dose and container size, which enhances both ease of operation and dose control
3Productivity
If the drug container capacity is smaller than the required dose, then the drug dose can be precisely controlled, but the injection time increases
Solution Approach 1:
The sliding attachment unit can be repositioned along the main body axis to accommodate different container capacities, allowing practitioners to use larger containers for multi-dose applications when productivity is prioritized, while still maintaining the ability to use smaller containers for precise single-dose control when needed

AI summary
A drug injecting implement equipped with a sliding attachment unit includes a main body having an accommodating space formed on the inside thereof, and equipped with a handle, an insertion needle having a solution flow pathway for a drug solution to flow therethrough, and of which one side is secured inside the main body while the other side extends outside the main body, an image measuring unit disposed on the main body, and of which one portion is formed in elongated fashion, a sliding attachment unit having an open topped accommodating unit for accommodating a separate drug container on the inside thereof, and which slides selectively on the side surface of the main body and a solution injecting unit provided on the main body and which is adapted such that the drug solution accommodated inside the drug container is injected into the human body via the insertion needle.
