View page
US Patent:
20190381249, Dec 19, 2019
Filed:
Mar 15, 2019
Appl. No.:
16/354675
Inventors:
- Exton PA, US
Jurgen BRINKHUES - Aachen, DE
Heike GRUEN - Aachen, DE
Joel WORMAN - Palm Harbor FL, US
Xia ZHAO - Malvern PA, US
Jason MATTIA - Downingtown PA, US
International Classification:
A61M 5/315
Abstract:
A pharmaceutical syringe piston having a longitudinal axis includes a body having a central face portion with a first outer circumference and maximum first diameter. A cylindrical sealing portion proximate the central face portion has first and second axial ends and a wall extending therebetween. The wall has a second outer circumference and a second diameter essentially constant along the longitudinal axis between the first and second axial ends of the cylindrical sealing portion and is larger than the maximum first diameter. An annular curved portion has a maximum outer diameter less than the second diameter and connects the first axial end of the cylindrical sealing portion to the first outer circumference. An inert film encloses the central face portion and at least part of the annular curved portion and has an outer boundary between the first axial end of the cylindrical sealing portion and the first outer circumference.
