Beschreibung
Zusammenfassung:	A Half-disposable syringe barrel including a barrel syringe and a cap member as two stages. A plunger is fitted in the syringe barrel. An emulsion ring is disposed in the cap member. The emulsion ring is formed with a membrane and is made of highly flexible material. A lubricant is overlaid on the emulsion ring and the membrane thereof. The cap member is fitted with the front end of the syringe barrel. When pulling the plunger backward to suck a medicine, the highly flexible membrane of the emulsion ring is extended and sucked to attach to the wall of the syringe barrel. Therefore, the medicine is enclosed by the emulsion ring and the membrane and isolated from the wall of the syringe barrel. Therefore, the syringe barrel and the plunger are not contaminated by the medicine and the flowing back blood. After the cap member is removed, the syringe barrel can be recovered for reuse.
