Abstract: A disposable safety syringe designed to prevent syringe handlers from being pricked by a needle by covering the needle with a needle shield, is provided. Special attention should be given to syringe needles because they are sharp enough to cause needle stick injuries before and after use. In particular, if a user is accidentally injured by a blood-stained needle, serious infections might be caused through the needle. Accordingly, the needle is covered with the needle shield after use. The needle shield is fitted over a syringe cylinder. A stopping tab prevents the needle shield from sliding off the cylinder. Inserting tabs are formed by cutting part of shield walls, and locking grooves are formed in the end of the inserting tabs. A fixing adapter has an engagement sill formed in the inner side thereof and a number of elastic fins in the outer side thereof, which is fitted on the locking tab of the needle fixer.

Abstract: The present invention provides a cationic group-containing amphiphilic block copolymer that is biocompatible and biodegradable, and when used as a drug carrier for an anionic drug, provides several advantages, such as increased blood concentration and improved stability of the drug.
