摘要：
#$%^&*AU2010210012B220120119.pdf#####16 ABSTRACT A retractable syringe and plunger therefor are provided, whereby the plunger comprises a pneumatic controlling means which facilitates control of the rate of retraction of the retractable needle when engaged with the plunger. By controlling the 5 rate of needle retraction, the likelihood of blood splattering is reduced thereby improving the user-friendliness and appeal of the retractable syringe. Typically, the syringe is a prefilled syringe. Following plunger depression, a symmetrical ejector member releases the retractable needle from a retaining member to thereby allow retraction of the retractable needle. The symmetrical ejector member does not require 10 alignment with said retaining member to release the retractable needle from the retaining member. Needle retraction is facilitated by a biasing means, such as a spring or other compressible and/or de-compressible device.17/18 341 340 381 342 382 320 370k 350 321 324 365 360 328 362 FIG. 17
