| 摘要 |
A centering syringe plunger guide (140) includes a guide body (141) including a proximal end (142) and a distal end (149), a coupling bore (143) extending partially into the guide body (141) from the proximal end (142), a precision guide bore (144) extending partially into the guide body (141) from the coupling bore (143), with the precision guide bore (144) adapted to fit over a barrel precision diameter of a syringe barrel and hold the centering syringe plunger guide (140) in a predetermined substantially coaxial alignment with the syringe barrel, and a guide plunger bore (145) extending completely from the precision guide bore (144) to the distal end (149) of the guide body (141). The guide plunger bore (145) is adapted to receive a syringe plunger and is configured to substantially center the syringe plunger in a plunger bore of the syringe barrel.
