Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Vascular access procedures in animals often result in occupational hazards due to the lack of barriers between needles and handlers, leading to percutaneous needle sticks during injection or withdrawal of substances.

Innovation Solution

The development of an injection device with a housing and injection guide opening that positions a body portion of an animal within a channel, shielding the handler from the needle and allowing precise penetration, and an injection plate designed to fit a finger and support an animal's ear, providing protection and accuracy during procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a needle is used for vascular access in animals, then the procedure can be performed, but the handler is exposed to percutaneous needle stick hazards

Engineering Contradiction:

Improveprocedural safetyVSAvoidneedle stick hazard

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a protective device that acts as an intermediary between the needle and the handler. The device includes a protective shield that covers the needle during insertion and withdrawal, and a restraining mechanism that secures the animal's body part, preventing accidental needle sticks while allowing the injection procedure to proceed safely

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the handler maintains direct contact with the animal during injection, then procedural control is improved, but the risk of needle stick increases

Engineering Contradiction:

Improveprocedural controlVSAvoidoccupational hazard

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The protective device is segmented into distinct functional components: a restraining portion that secures the animal's body part, a protective shield that isolates the needle, and an injection access portion that allows controlled needle insertion. This segmentation enables the handler to maintain procedural control through the designed interfaces while being physically protected from needle exposure

Inventive Principle:

Principle #1Segmentation

3Reliability

If a protective barrier is introduced between the needle and handler, then safety is improved, but device complexity increases

Engineering Contradiction:

Improvehandler protectionVSAvoiddevice structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple protective functions into a single integrated device structure. The protective shield, restraining mechanism, and injection access points are combined into one cohesive apparatus that can be applied to the animal's body part, reducing the number of separate components and simplifying the overall device while maintaining comprehensive protection

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Disclosed herein is an injection device with housing that defines a channel and a first injection guide opening. The first injection guide opening enters the channel in a manner that allows a needle to penetrate a vessel in an animal with accuracy and at the same time protect the user from the needle.
