    • PROBLEM TO BE SOLVED: To provide an easily portable jet type syringe suitable for insulin injection for diabetes, gene therapy drug injection, and vaccination. SOLUTION: In this jet type syringe, a nozzle 101B comprising a jet nozzle 104 opening at the distal end, a cylinder 105 communicating with the jet nozzle 104, a drug solution storage chamber 106A formed along the circumference of the cylinder 105, and a ring shape rubber stopper 200 which slides and fits into the drug solution storage chamber 106A by pressure difference between inside and outside of the drug solution storage chamber 106A and is movable blocking an air flow along the axis is detachably connected to the syringe body. Because the drug solution storage chamber 106A is set along the circumference of the cylinder 105, the outer diameter of the whole syringe including a nozzle 101B can be made slim and the storage chamber 106A can store a volume of drug solution more than several times the drug solution which the cylinder 105can store, whereby eliminating the need to carry drug solution vials.

    • 要解决的问题:提供一种适用于胰岛素注射用于糖尿病,基因治疗药物注射和疫苗接种的便携式喷射型注射器。 解决方案:在该喷射式注射器中,包括在远端开口的喷嘴104的喷嘴101B,与喷嘴104连通的圆筒105,沿着圆筒105的圆周形成的药液存储室106A, 以及通过药液存储室106A的内外的压力差而滑动并配合到药液容纳室106A的环形橡胶塞子200,并且可阻止沿着轴线的空气流动的可移动地可拆卸地连接到注射器主体。 由于药液存储室106A沿着圆筒105的圆周设置,所以包括喷嘴101B的整个注射器的外径可以变薄,并且储存室106A可以将一定量的药物溶液存储多于药物的几倍 气瓶105可以存储的溶液,从而消除了携带药物溶液瓶的需要。 版权所有(C)2005,JPO&NCIPI
