ABSTRACT:
A retractable syringe includes a barrel, one end of which comprises a mounting collar. A needle carrier is releasably mounted within the collar and releaseably supports a needle cartridge. A hypodermic needle is mounted within the cartridge. A sheath attaches at one end of the cartridge and at the other end of the collar. A plunger is telescoped into the barrel and includes a piston sealingly engaging the barrel. The piston includes a latch for engaging the carrier and releasing it from the collar. The piston and carrier also include an anti-remount mechanism preventing the carrier from being reengaged into the collar. To preform this, a separate tool is used to insert the carrier into the collar. The plunger further includes surfaces to displace fluid as the piston is forced toward the proximal end of the barrel to displace fluid to reduce squirt. A cap is also provided to initially seal off the proximal end of the barrel and after usage to form a seal by engaging teeth within the proximal end of the barrel.
