To provide a drug solution preparing kit which can be handled with ease in a substantially aseptic manner, and has no risk that a leakage of a drug solution such as a splash and a dispersion of an aerosol to an ambient environment occurs upon preparation of the drug solution There is provided a drug solution preparing kit including a pre-filled syringe and a transfusing tool, wherein the pre-filled syringe includes a sealing member which seals the tip end and can not be removed from the tip end, and that the transfusing tool includes a one-way valve which can discharge only gas from the system in an irreversible manner, and a filter which is provided so as to adjoin to the second communication channel with respect to the one-way valve.

Drug solution preparing kit

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.

Drug solution transferring device

The kit for suppressing drug craving K is used by connecting an instrument for suppressing drug cravingto a syringeand the instrument for suppressing drug cravinghas a cylindrical housing, a pouchprovided in the housing and containing pseudo-blood B and a connecting memberwith 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.()), and if the plungeris pulled back from this condition, the pouchdeflates and the pseudo-blood B flows back from the pouchto the syringe(flashback) (FIG.(C)).
