Autoinjector Cap Integrating Antiseptic Dressing Receptacle
Solution Overview
Problem
Conventional autoinjectors lack a convenient and compact method to integrate antiseptic and antibacterial solutions for pre- and post-injection treatments, especially for self-administration where separate swabs and solutions may not be readily available.
Innovation Solution
An autoinjector cap system that integrates an antibacterial element receptacle, featuring a removable cover and storage compartment for antiseptic-soaked dressings, which can be retrofitted onto existing autoinjectors, including an expiration timer and locking mechanism to prevent use of expired medications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate swabs and antiseptic solutions are used for pre-injection treatment, then the injection site can be disinfected, but the system becomes bulky and difficult to carry and transport
Solution Approach 1:
The patent combines the antiseptic solution reservoir, dressing applicator, and storage compartment into a single integrated cap assembly that attaches to the autoinjector. This merging of previously separate components (swabs and antiseptic bottles) into one compact unit resolves the contradiction by maintaining disinfection capability while dramatically reducing transport volume.
Solution Approach 2:
The cap assembly serves multiple functions: it stores the antiseptic solution, applies it to the injection site, covers the needle when not in use, and provides post-injection treatment materials. This multi-functionality allows a single compact component to replace multiple separate items, resolving the volume contradiction while maintaining comprehensive treatment capability.
2Ease of operation
If a compact integrated package is created to combine swabs and antiseptic solution, then transport convenience is improved, but the device complexity increases
Solution Approach 1:
The patent employs a nested structure where the dressing applicator is contained within the cap assembly, the antiseptic solution is stored in a reservoir within the same assembly, and post-injection materials are stored in a compartment within the cap. This nesting of components within each other creates a compact integrated package that improves transport convenience while managing complexity through hierarchical organization.
3Reliability
If the antiseptic-soaked dressing is mounted into the removable cover, then the cap assembly can be locked to the autoinjector body, but the administrator must remove the cap assembly for pre-injection treatment
Solution Approach 1:
The cap assembly is designed with dynamic characteristics - it can be securely locked to the autoinjector body via the locking mechanism for storage and transport, but can be easily removed when needed for pre-injection treatment. This dynamic ability to transition between locked and unlocked states resolves the contradiction by providing both security and accessibility at different operational stages.

AI summary
A system for integrating an antibacterial-element receptacle into an autoinjector cap facilitates the pre-injection treatment, the post-injection treatment, and prevents the accidental delivery of the injection. The system includes a cap assembly, an autoinjector body, and an antiseptic-soaked dressing. The cap assembly encloses the needle of the autoinjector and prevents the accidental trigger of the injection mechanism. The autoinjector body refers to the body of any conventional autoinjector. The antiseptic-soaked dressing is applied to the patient's skin prior to the delivery of the injection to disinfect and sterilize the injection area. The antiseptic-soaked dressing is housed in the cap assembly, between a receptacle and a removable cover. The removable cover is releasably mounted to the receptacle to allow access to the antiseptic-soaked dressing.
