Jet Injection Syringes TRIZ Cases
- Needleless Syringe with Transversal Slots for Particle Penetration
A needleless syringe uses transversal slots in a gas cannon to accelerate therapeutic particles through staged pressure release.
- Liquid Jet Discharge Device Using Pressure Wave and Staggered Interface
A liquid jet discharge device uses a pressure wave in a transmission medium to eject a focused jet from a narrow tube.
- Needleless Skin Filler Injection Device with Negative Pressure and Vibration
A needleless injection device uses negative pressure cooling and low-frequency vibration to facilitate precise subcutaneous liquid delivery.
- Nasal Aerosol Delivery Device Using Fluidodynamic Expansion
A manual nasal delivery device nebulizes liquid substances into aerosols using an annular expansion and acceleration chamber.
- Autoinjector Frontal Buttress for Accurate Needle Depth
Frontal buttress registers syringe shoulder to ensure accurate needle depth and reduce flange fracture risk.
