1. A syringe comprising:
- a handle having a first flange and a second flange forming a handgrip;
a first arc forming a bottom surface of the first flange contoured to correspond to a radius of an arc formed by a user'"'"'s fingers;
a second arc forming a bottom surface of the second flange contoured to correspond to a radius of an arc formed by the user'"'"'s fingers and shaped flatter than the first arc;
a syringe barrel having an outer barrel and an inner barrel, the inner barrel having dosage marks and a needle mounted at a distal end, the outer barrel shaped to receive the inner barrel and having an elliptical cross section to magnify the dosage marks located on the inner barrel; and
a tip cap slidably engageable with a distal end of the syringe barrel for shielding the needle comprising,an outer cap;
an inner cap; and
a connector shaped to fit within and engage the outer cap and engage the inner cap and having a plurality of first legs spaced symmetrically away from one another, each first leg having a plurality of internally facing barbs pointing toward a distal region of the connector and adapted to engage a proximal region of the inner cap, wherein the plurality of internally facing barbs are disposed at an angle with respect to the plurality of first legs, the connector having a plurality of second legs spaced symmetrically away from one another, each second leg having a plurality of externally facing barbs located in the distal region of the connector and adapted to engage a distal region of the outer cap;
wherein the outer barrel includes a first recess and a second recess shaped to receive the tip cap.
