Disposable Injection Devices with Distinctive Marks for Site Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients with chronic conditions, such as diabetes, face complications from repeated injections at the same site, including the formation of fibrocollagenous scar tissue, localized lipodystrophy, and changes in insulin absorption due to inadequate injection site rotation and reuse of needles, leading to variable glucose levels and reduced injection site availability.
Innovation Solution
A kit and method that include disposable injection devices with unique distinctive marks and user-defined association tools, such as temporary tattoos or stickers, to facilitate a personalized injection site rotation plan, allowing patients to create and adhere to a customized injection routine, with options for sequential or randomized dispensing of devices to promote site rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disposable injection devices are made sterile and single-use, then infection risk is reduced, but device complexity and cost increase
Solution Approach 1:
The patent employs disposable injection devices that are sterile, single-use items designed to be discarded after one use. This eliminates infection risk from needle reuse while keeping each individual device relatively simple in structure. The disposable nature ensures reliability without requiring complex sterilization or tracking systems.
2Duration of action of stationary object
If injection sites are reused, then treatment continuity is maintained, but tissue trauma and lipohypertrophy increase
Solution Approach 1:
The patent divides the injection routine into segments by introducing distinctive marks on disposable devices that correspond to specific injection sites. Patients rotate through multiple marked devices, each designated for a different anatomical location. This segmentation ensures treatment continuity while systematically distributing trauma across different tissue areas, preventing lipohypertrophy.
3Reliability
If patients follow strict injection site rotation protocols, then tissue health is preserved, but patient compliance becomes difficult to maintain
Solution Approach 1:
The patent uses distinctive visual marks (colors, patterns, or symbols) on disposable injection devices that correspond to specific injection sites. Patients simply match the mark on the device to the corresponding marked area on their body or rotation chart, eliminating the need to remember complex rotation schedules. This visual guidance system maintains tissue health while dramatically improving patient compliance.
4Ease of operation
If injection devices include distinctive marks for rotation tracking, then site rotation compliance improves, but device manufacturing complexity increases
Solution Approach 1:
The patent incorporates distinctive marks such as colors, patterns, or symbols on the disposable injection devices. These visual indicators are applied during manufacturing using standard printing or marking techniques, adding minimal complexity to the production process. The marks enable easy patient compliance with rotation protocols while maintaining manufacturing efficiency.
