Integrated Syringe Light for Oral Anesthesia
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current oral anesthesia injection syringes face challenges in illuminating the interior of a patient's mouth due to limited access and the need for manual repositioning of external lights, which can impede the procedure and require additional hands.
Innovation Solution
A self-contained light system integrated within the oral anesthesia syringe barrel, powered by a battery, that illuminates the needle and injection site within the mouth, allowing hands-free operation and eliminating the need for external power sources or additional lighting adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light mounted on a movable arm is used to illuminate the inside of the patient's mouth, then illumination is provided, but the dentist's head and hands impede illumination and the light must be repositioned between injections
Solution Approach 1:
The light source is merged with the syringe assembly, creating an integrated unit where the illumination device becomes part of the injection system. This eliminates the need for separate external lighting equipment and allows the light to follow the syringe as it moves between injection sites, providing continuous illumination without requiring the dentist to reposition external lights or use additional hands for light management.
2Illumination intensity
If a light mounted on a movable arm is used, then illumination is provided, but additional hands are required to manage positioning
Solution Approach 1:
The light source is merged with the syringe assembly, creating an integrated unit where the illumination device becomes part of the injection system. This eliminates the need for separate external lighting equipment and allows the light to follow the syringe as it moves between injection sites, providing continuous illumination without requiring the dentist to reposition external lights or use additional hands for light management.
3Illumination intensity
If external lighting equipment is used, then illumination is provided, but access to the inside of the mouth is limited by the size of the mouth opening
Solution Approach 1:
The light source is merged with the syringe assembly, creating an integrated unit where the illumination device becomes part of the injection system. This eliminates the need for separate external lighting equipment and allows the light to follow the syringe as it moves between injection sites, providing continuous illumination without requiring the dentist to reposition external lights or use additional hands for light management.
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
Provides consistent, hands-free illumination of the injection site, enhancing procedural efficiency and safety by ensuring adequate lighting without the need for manual repositioning or additional hands, while also offering a single-use, disposable solution to reduce cross-contamination risks.
Implementation Method 1
A battery is provided in the light for powering the lamps
Implementation Method 2
At least one lamp and preferably a plurality of lamps at the distal end of the barrel illuminate the needle and the interior of a patient's mouth
Data Source
AI summary
A light for use with an oral anesthesia syringe that is received into a passageway of a barrel of the light. When the syringe is received into a first opening in a proximal end of the barrel's passageway, the needle of the syringe extends through a second opening at the proximal end of the barrel. At least one lamp and preferably a plurality of lamps at the distal end of the barrel illuminate the needle and the interior of a patient's mouth. A battery is included in the light for powering the lamps. The insertion of the syringe into the barrel may a pair of contacts to cause the battery to power the lamps, or the battery may be removed to remove power from the lamps. A disposable integrated syringe and light combination is also described.
