摘要：
A safety syringe 10 includes a barrel 18, plunger assembly 12, and barrel adapter 20. A barrel adapter 20 mountable to a syringe barrel 18 includes a barrel tip 32, needle assembly 42, and needle retraction mechanism 21. The needle assembly 42 includes a needle hub 24, needle seal 26, and needle 29, which is configured to pass-through the needle assembly 42, locking mechanism 22, biasing member 30, and barrel tip 32. The needle retraction mechanism 21 includes a biasing member 30 and locking mechanism 22 such that actuation of the locking mechanism 22 allows the biasing member 30 to cause retraction of the needle 28 into the barrel tip 32. Methods of assembling, manufacturing, and using such syringes 10 are also provided.一種安全性注射器(10)係包含長筒(18)、柱塞組件(12)以及長筒接合器(20)。可安裝於注射器長筒(18)之長筒接合器(20)包含筒尖(32)、注射針組件(42)及注射針回縮機構(21)。該注射針組件(42)係包含針座(24)、注射針密封墊(26)及注射針(28),其組構成穿透該注射針組件(42)、鎖止機構(22)、偏壓構件(30)及筒尖(32)。該注射針回縮機構(21)係包含偏壓構件(30)及鎖止機構(22)使得該鎖止機構(22)之啟動可讓該偏壓構件(30)促使注射針(28)縮回進入筒尖(32)。亦提供本注射器(10)之組裝、製造及使用方法。10‧‧‧注射器12‧‧‧柱塞組件14‧‧‧柱塞棒16‧‧‧柱塞密封墊18‧‧‧長筒20‧‧‧長筒接合器22‧‧‧鎖止機構24‧‧‧注射針座26‧‧‧注射針密封墊28‧‧‧注射針30‧‧‧偏壓構件32‧‧‧筒尖32a‧‧‧鎖止體34‧‧‧注射針套36‧‧‧O型環38‧‧‧硬質注射針罩42‧‧‧注射針組件
