  • Publication number: 20110004185
    Abstract: A drug solution transferring device that can suppress dispersion of a toxic drug solution to a surrounding environment is provided. The drug solution transferring device includes a barrel provided with an opening, and a connection tool for connection to the barrel. The barrel includes an elastic member for closing the opening. The elastic member is formed of a plurality of membranes overlaid together. The membrane has a projection projecting into the barrel. The connection tool includes a first needle having a sharp tip end. The first needle has a liquid hole extending in an extending direction of the first needle. When the needle penetrates through the projection of the membrane, an inside and an outside of the barrel are in communication with each other through the liquid hole to allow transference of the drug solution between the barrel and the connection tool.

  • Publication number: 20100211018
    Abstract: The kit for suppressing drug craving K is used by connecting an instrument for suppressing drug craving 1 to a syringe 2 and the instrument for suppressing drug craving 1 has a cylindrical housing 11, a pouch 12 provided in the housing and containing pseudo-blood B and a connecting member 13 with which the distal end of a syringe is coupled and which cause the syringe to communicate with the interior of the pouch. When the syringe accommodating pseudo-drug M is connected to the instrument and the plunger is moved forward (pseudo-priming), the pseudo-drug M flows into a pouch and the pouch inflates (FIG. 2(b)), and if the plunger 4 is pulled back from this condition, the pouch 12 deflates and the pseudo-blood B flows back from the pouch 12 to the syringe 2 (flashback) (FIG. 2(C)).
