DOSE DIVIDER SYRINGE

摘要

A syringe includes a barrel having an internal surface defining an internal bore therein; a plunger having a distal end disposed within the internal bore of the barrel, and a proximal end disposed outside the internal bore of the barrel, the proximal end of the plunger being opposite the distal end of the plunger along a longitudinal direction; and a dose divider. The dose divider includes a divider flange extending at least partly in a radial direction, the radial direction being perpendicular to the longitudinal direction, the divider flange having a distal surface that faces the barrel, the distal surface of the divider flange bearing on the proximal end of the plunger, and a concave shell extending away from the distal surface of the divider flange along the longitudinal direction.

1. A dose divider for a syringe, the dose divider comprising:
a flange extending at least partly in a radial direction; and a concave shell extending away from the flange along a longitudinal direction, the longitudinal direction being perpendicular to the radial direction, a proximal end of the concave shell being disposed on the flange, and a distal end of the concave shell being opposite the proximal end of the concave shell along the longitudinal direction, the concave shell extending in a circumferential direction about an axis from a first circumferential edge to a second circumferential edge, the axis being aligned with the longitudinal direction, and the first circumferential edge being separated from the second circumferential edge by a gap distance.
