Claims (1)
塞して内部に薬液を充填した内シリンジと、前記
内シリンジを摺動可能に内装し前端に中空両方向
針を具えた外シリンジと、前記外シリンジの前部
に摺動可能に装着され前端をセプタムで封塞した
ガイド部と、前記プランジヤの後部に突設された
ステムと、前記外シリンジの内部で内シリンジの
後部に摺動可能に嵌装されたフリーピストンとを
具え、ガイド部前端を相手容器に当て外シリンジ
を押すことにより両方向針の前部がガイド部及び
相手容器のセプタムを貫通し、次にプランジヤの
ステムを押すことにより内シリンジが前進し、両
方向針の後部が内シリンジ前端のセプタムを貫通
し、薬液が中空両方向針を通り相手容器に注入さ
れるようにしたことを特徴とする二重シリンジ。 an inner syringe whose front end is sealed with a septum and whose rear end is sealed with a plunger and filled with a drug solution; an outer syringe with the inner syringe slidably inside and equipped with a hollow bidirectional needle at the front end; a guide portion that is slidably attached to the front portion of the syringe and whose front end is sealed with a septum; a stem that projects from the rear portion of the plunger; and a guide portion that is slidably fitted to the rear portion of the inner syringe inside the outer syringe. The front end of the bidirectional needle passes through the guide part and the septum of the mating container by placing the front end of the guide part against the mating container and pushing the external syringe, and then by pushing the stem of the plunger, the internal syringe is inserted. A double syringe characterized in that when the syringe moves forward, the rear part of the bidirectional needle penetrates the septum at the front end of the inner syringe, and the medicinal solution passes through the hollow bidirectional needle and is injected into the mating container.
