Peritonsillar Abscess Aspiration Kit with Guard-Actuator System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current peritonsillar abscess aspiration procedures lack a standardized kit that ensures secure configuration of components, leading to potential human error and failure in aspirating abscesses without unintentionally hitting critical tissues.
Innovation Solution
A peritonsillar abscess aspiration kit comprising a hollow aspiration needle with a tapered distal tip, an aspiration needle guard, an anesthetic application needle, and a syringe actuator, all designed to securely attach and detach to prevent misplacement and ensure accurate aspiration, with components pre-assembled for ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standardized peritonsillar aspiration kit is implemented, then reliability and safety are improved, but device complexity increases due to multiple pre-assembled components
Solution Approach 1:
The aspiration system is divided into distinct segments: needle assembly, syringe assembly, and guard assembly. Each component can be independently manufactured, sterilized, and quality-controlled, then pre-assembled into a standardized kit configuration that ensures proper compatibility and reduces assembly errors during procedure.
Solution Approach 2:
The needle is inserted through the guard assembly, with the guard acting as a protective outer structure. The syringe connects to the needle hub, creating a nested configuration where smaller components are housed within larger ones. This nesting ensures proper component alignment and prevents misuse.
2Ease of operation
If the needle guard length is made shorter than the needle length, then ease of operation is improved by allowing adequate needle extension, but reliability deteriorates due to potential needle exposure risks
Solution Approach 1:
The guard assembly is designed with dynamic characteristics allowing it to be positioned at different depths during insertion, with the distal end serving as a depth indicator. The guard can be fully inserted to protect the needle, then advanced further to indicate proper insertion depth, providing operational flexibility while maintaining safety.
Solution Approach 2:
The guard assembly acts as an intermediary element between the needle and the external environment. It provides a protective barrier during storage and transport, then serves as a depth indicator during use, mediating between the need for needle protection and the need for adequate needle extension.
3Ease of operation
If pre-assembled components are used, then ease of operation is improved, but device complexity increases due to standardized configuration requirements
Solution Approach 1:
The kit components are pre-assembled and sterilized together as a complete system before use. The needle is pre-attached to the syringe, and the guard is pre-positioned, eliminating the need for complex assembly procedures during the medical procedure. This preliminary preparation simplifies the user's task while ensuring proper component compatibility.

AI summary
A peritonsillar abscess aspiration kit. The kit includes at least one aspiration needle and one anesthetic application needle. Each needle has a corresponding needle guard and guard cap configured to house the needle. In addition, each needle has a length greater than the needle guard. The kit further includes at least one syringe configured to attach to the needles and a syringe actuator. The syringe actuator is configured to securely house the syringe and includes a pistol grip and a trigger configured to translate a plunger in the syringe when the trigger is pulled.
