Vibrating Syringe Housing for Less Painful Injections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Injections cause discomfort and pain due to piercing of the skin and subcutaneous tissues, which is particularly challenging for children and infants, and existing solutions like vibrating syringes or needles are either impractical or harmful.
Innovation Solution
A device with a vibrating mechanism is integrated into the housing of a syringe apparatus, which applies vibration to the skin and subcutaneous tissues before and during the injection to desensitize nerve endings, reducing pain by confusing or masking nerve impulses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If vibration is applied to the syringe during injection, then pain reduction may be achieved, but the syringe becomes difficult to hold and control
Solution Approach 1:
The device separates the vibration function from the syringe by using a distinct vibration mechanism attached to or near the syringe barrel, allowing the needle to remain stable while the vibration is applied to the skin and syringe body for pain reduction
Solution Approach 2:
The vibration mechanism acts as an intermediary that transfers vibrational energy to the skin and syringe without requiring the syringe itself to be the vibration source, thus reducing pain while maintaining control
2Object-affected harmful factors
If a vibrating needle is used, then pain reduction may be achieved, but the device becomes difficult and expensive to manufacture and may tear tissues
Solution Approach 1:
The vibration function is extracted from the needle and placed in a separate vibration mechanism that acts on the skin and syringe barrel, eliminating the need for complex vibrating needle construction while achieving pain reduction
Solution Approach 2:
The patent uses mechanical vibration applied to the skin and syringe barrel rather than the needle itself, achieving pain reduction through tissue desensitization without the manufacturing complexity and tissue damage risks of vibrating needles
3Loss of time
If the needle is advanced quickly to reduce pain, then injection time is reduced, but the risk of tissue damage and patient discomfort increases
Solution Approach 1:
The vibration mechanism is activated before needle insertion and continues during injection to pre-desensitize the skin and tissues, allowing for safer and more comfortable needle advancement without requiring extremely rapid insertion
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 device effectively reduces or eliminates pain during injections by applying mechanical excitation to the skin and tissues, making the procedure less distressing for patients, particularly children and infants, while being practical and safe to use.
Implementation Method 1
vibration or other similar mechanical excitation is applied to the skin and the subcutaneous tissues at the injection site
