Medication Support Device with Pinching Arms and Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for insulin delivery, such as syringes and pens, often result in inconsistent needle placement and depth due to manual pinching and alignment challenges, leading to variable medication delivery.
Innovation Solution
A support assembly with biased arms that grip and pinch the skin to create a raised surface, coupled with a guide and holder for the delivery device, ensuring consistent needle placement and controlled depth of injection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual pinching and alignment is used for needle insertion, then the device structure remains simple, but needle placement consistency and injection depth control deteriorate
Solution Approach 1:
The patent introduces a support device as an intermediary tool between the user and the needle insertion process. The support device includes a pinching mechanism that grasps the skin and a guide structure that directs the needle, thereby mediating the insertion process to achieve consistent placement without requiring complex manual coordination
Solution Approach 2:
The support device performs preliminary actions by first pinching the skin to create a raised surface and then providing a guide structure that pre-establishes the correct needle insertion path and depth before the actual injection occurs, ensuring consistent results
2Reliability
If manual pinching of skin is performed, then no additional device components are needed, but injection depth control and needle alignment deteriorate
Solution Approach 1:
The support device serves as a mediator that simplifies the operation by providing a ready-to-use pinching mechanism and guide structure. The user simply needs to attach the support device to the skin, and the device automatically performs the pinching and alignment functions, making the operation easier while improving reliability
Solution Approach 2:
The support device is designed to be self-sufficient, with the pinching mechanism automatically grasping the skin and the guide structure automatically directing the needle insertion. The device serves itself by providing all necessary guidance and positioning functions without requiring complex user manipulation
3Manufacturing precision
If consistent skin pinching and alignment are provided, then medication delivery consistency improves, but device structure and complexity increase
Solution Approach 1:
The support device is segmented into distinct functional components: a pinching mechanism for grasping the skin, a guide structure for needle alignment, and a holder for securing the delivery device. This segmentation allows each component to perform its specific function efficiently while keeping the overall design relatively simple and manufacturable
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The support assembly facilitates consistent and controlled delivery of insulin by maintaining the needle at a precise depth and orientation, improving the accuracy and reliability of medication administration.
Implementation Method 1
The arms are biased inwardly toward each other and toward the center axis of the support for gathering or pinching the tissue

AI summary
A support (10) for a delivery device, such as a syringe (18) or pen needle delivery device, includes an adapter (12), a guide (16) for coupling to the adapter, and holder (14) for the delivery device that is able to slide relative to the adapter. The adapter includes movable arms (30) for gripping or pinching the tissue of the patient into raised, bulged area. The guide (16) is coupled to the adapter between the arms of the adapter to guide the delivery device into a position where the needle can access the tissue between the arms. The holder for the delivery device slides in the guide to guide the needle of the delivery device into the tissue between the arms to a controlled depth for introducing the medication to the patient.
