Ampoule Syringes TRIZ Cases
- Injection Device Plunger Speed Control via Sensor Feedback
Sensor feedback reduces plunger advancement speed upon detecting stopper proximity, preventing unintentional substance discharge from syringes.
- Injection Pen Unidirectional Ratchet Mechanism
A syringe injection assembly uses a unidirectional ratchet mechanism to convert linear pushing force into controlled rotational motion for dose metering.
- Endothermic Gas Syringe Attachment for Pain-Free Injection
Syringe receptacle holds compressed endothermic gas canister that rapidly absorbs heat upon release to numb the injection site before needle insertion.
- Drug Delivery Device Back-Off Mechanism Eliminates Priming
A drug delivery device mechanism moves a piston rod away from a bung after dose delivery to maintain a predetermined initial distance.
