Auto-Injecting Capsule for Emergency Medicament Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for parenteral medication administration, such as injections, are often not timely or controlled, especially in emergency situations where patients may not be aware of their condition or unable to administer medication themselves, leading to potential severe outcomes like sudden death or severe physical and cognitive damages.
Innovation Solution
A self-contained injection capsule system that allows for automatic or simple manual administration of medication via a needle, integrated with sensors and a control unit for real-time symptom detection and pre-programmed action, eliminating the need for medical professionals and reducing environmental impact through a disposable, hermetically sealed design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional syringe and needle packaging methods are used, then sterilization and handling are established, but environmental impact increases and complexity increases
Solution Approach 1:
The patent combines the syringe barrel, needle, and medication into a single integrated auto-injector device. The needle is permanently attached to the syringe barrel, and the medication is pre-filled in the barrel, eliminating the need for separate packaging and sterilization procedures for each component. This merging reduces environmental impact while maintaining sterility through the integrated design.
Solution Approach 2:
The auto-injector is designed as a disposable single-use device. After one use, the entire device including needle, syringe, and medication container is discarded. This eliminates the need for complex sterilization and repackaging procedures, reducing environmental impact from repeated sterilization cycles while ensuring sterility through factory-sealed disposable construction.
2Reliability
If manual injection administration is used, then flexibility is maintained, but timing and control are insufficient in emergency situations
Solution Approach 1:
The auto-injector is designed to automatically perform the injection process without requiring manual manipulation. When activated, the device automatically advances the needle, injects the medication at controlled rates, and retracts the needle. This self-service mechanism ensures timely and controlled administration while minimizing the physical actions required by the user, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The device is pre-loaded with the medication and needle assembly before use. The syringe is pre-filled with the exact dose required, and the needle is pre-attached and positioned. This preliminary preparation ensures that when emergency situations occur, the device can immediately administer medication without requiring assembly or manual preparation, achieving both timely administration and ease of operation.
3Reliability
If hermetic sealing is implemented, then sterility is maintained, but device complexity increases
Solution Approach 1:
The device uses a disposable hermetically sealed cartridge containing the medication. The seal is maintained through simple factory-applied barriers that are sufficient for single-use applications. This approach maintains sterility through hermetic sealing while avoiding the complexity of reusable密封 mechanisms, as the entire cartridge is discarded after one use.
Solution Approach 2:
The hermetic seal is achieved using thin flexible films and membranes that close the syringe barrel and medication reservoir. These thin-film barriers provide adequate hermetic sealing for single-use applications without requiring complex mechanical seal structures. The flexibility of these films allows for simple integration into the disposable device architecture while maintaining sterility.

AI summary
An injection capsule for medical use, having:a closed main body having an internal reservoir receiving a medical substance in liquid form to be administered to a target subject; anda needle, having one or more inlet bores located at its lateral skirt and configured to allow the inlet of the medical substance within its tubular body. The needle is activatable between a rest configuration, wherein it is housed within the reservoir and immersed in the medical substance, and an injection configuration, wherein it is pushed outside the closed main body to administer the medical substance by injection to the target subject.
