Automatic Syringes TRIZ Cases
- Polymeric Acid Gas Generation for Controlled Drug Delivery
Adjusting polymeric acid cross-linking and concentration modulates reaction rate, resolving rapid gas generation that causes unpredictable drug delivery.
- Autoinjector Key Deformation for Injection Completion Feedback
A piston rod pulls a key shaft to deform tabs, generating audible cues that confirm complete fluid delivery.
- Automatic Intravenous Injection System with Sensor-Guided Vein Detection
Sensor-guided automatic injection system identifies vein position using infrared and optical detection to eliminate manual venipuncture errors.
- Reusable Auto-Injector with Fluid Transfer Assembly
Segmenting the device into reusable and disposable subassemblies reduces manufacturing complexity while maintaining immediate readiness for use.
- Drug Delivery Device Guard Lockout and Feedback
A drug delivery device uses a drive mechanism to expel medication through a plunger.
- Drug Delivery System with Exposure Monitoring Sensors
Sensors track temperature, humidity, and light exposure to determine drug viability, preventing the administration of compromised medication.
- Blinding Kit Segmentation for Clinical Trial Injection
Segmenting opaque containers from injection needles with intermediary connectors maintains blinding effectiveness while reducing device complexity.
- Injector Activation Button Assembly with Threshold Locking
A biasing member drives an injection needle from a retracted position to an injection position within the activation button assembly.
