This drug delivery device delivers a drug between a syringe barrel and a drug container, and, by enveloping the entire the drug container used in drug delivery, prevents exposure to hazardous drugs adhering to the drug container. This drug delivery device includes: a first member connected to the drug container on the side of a stopper; a second member connected to the first member and to the syringe barrel; and a third member connected to the first member and covering the drug container in a sealed state. The first member has a first hollow needle member and a drug container holder, and the second member has a second hollow needle member. The third member has an opening portion, a bottom surface portion where the drug container is stably mounted, and a flexible member which is connected to the opening portion and the bottom surface portion.

1. A drug delivery device that has a first member which is connected to a stopper side of a drug delivery device, a second member which is connected at one end thereof to said first member and which is connected at another end thereof to a syringe barrel, and a third device which is connected to the first member and which is for covering the drug container in a sealed state; and that carries out delivery of a drug between the drug container and the syringe barrel, the drug delivery device characterized in that:
the first member has
a first hollow needle member having a tip portion arranged so as to be directed toward the stopper side of the drug delivery device, and having a base portion arranged so as to be directed toward the second member, the base portion and the tip portion each being provided with a hole for delivery of the drug; anda drug container gripping portion that allows a size of a region at which connection occurs to be varied in correspondence to a magnitude of an outside diameter at the drug container stopper portion, and that squeezes on and holds the drug container stopper; the second member has
a second hollow needle member having a tip portion arranged so as to be directed toward the first member, and having a base portion arranged so as to be directed toward the syringe barrel, the base portion and the tip portion each being provided with a hole for delivery of the drug; and the third member has
an open portion;a bottom portion permitting stable placement of the drug container thereon; anda flexible member that is connected at one end thereof to the open portion and is connected at another end thereof to the bottom portion, that allows the drug container when placed on the bottom portion to be visible from an exterior side, that is of adjustable height, and that covers the drug container; wherein mounting the open portion on the first member while in a state in which the flexible member covers the drug container gripping portion causes the first member and the third member to be mutually connected while an interior of the third member is in a sealed state; wherein, when the first member and the second member are mutually connected, the second hollow needle member is inserted within the first hollow needle member which is inserted in the stopper of the drug container; and wherein, after the drug container gripping portion has caused the connected relationship between the drug container and the first member to become fixed, delivery of the drug between the drug container and the syringe barrel is carried out by way of the first hollow needle member and the second hollow needle member which is inserted within said first hollow needle member.
