摘要：
An injection device has a generally disc-shaped housing including an arcuate clear section and graduated markings in an arcuate arrangement on or adjacent to the clear section. An arcuately expandable member is contained within the housing and is configured to hold a volume of liquid. An indicator is connected to the expandable member and positioned within the housing. The indicator is configured to move along an arcuate path adjacent to the clear section such that alignment of the indicator with the graduated markings indicates a volume of liquid within the expandable member.
