BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an infusion device, and more particularly to an infusion device (container) used for intravenous injection.

0002

[Prior Art] Conventionally, in medical institutions such as hospitals,
Powdered drugs or freeze-dried drugs in containers such as vials are dissolved and used as an infusion solution for intravenous injection.
The container containing the drug and the container containing the solution of the drug are connected using a connecting tool such as a double-ended needle or a connecting tube, and the solution is transferred to the container containing the drug to dissolve the drug. .

[0003] However, this operation is complicated and time-consuming, and since the connection hole is made in the container containing the drug in the open air, there is a possibility that the drug inside may become contaminated.

[0004] In order to solve the above-mentioned problems, an infusion device (container) as disclosed in Japanese Patent Publication No. 1988-501129 has been proposed.

As shown in FIG. 4, this infusion device includes a capsule (102) containing a vial (101) which is a drug container, and a flexible container (103) containing a solution having a drug solution outlet. ) are connected by a tube (104). Inside the tube (104), a hollow puncture needle (105) is attached to the vial (101) side, and a breaking member (106) is attached to the flexible container (103) side.
is attached. The breaking member (106) closes the passage within the tube (104) and prevents the flow of liquid.

In use, press the cap (107) on the top of the capsule (102) with your finger to remove the vial (101).
is pushed down and the puncture needle (105) pierces the rubber stopper (108) of the vial (101) to first connect the flexible container (103) and the vial (101). Next, the tube (1
The breaking member (106) in the tube (104) is manually bent to open a passage in the tube (104) and mix the drug and the solution.

[0007]

[Problems to be Solved by the Invention] However, in the above-mentioned infusion device, although it has been improved in communicating and mixing the drug container and the flexible device containing the solution, the puncture needle (105 ) by vial (101
) is pierced through the rubber stopper (108), and then the breakable member (10
6) by hand to open the passage, which still requires considerable effort. Furthermore, if the breakable member (106) is imperfectly bent, there is a problem in that it is difficult for the liquid to pass through and it takes a long time to dissolve. Furthermore, since there are many parts, there is also the problem that the cost is high.

[0008] The present invention was made in view of the above-mentioned problems, and it ensures and facilitates communication between a drug container and a container for dissolving liquid or diluting liquid (hereinafter referred to as dissolving liquid) with a simple structure, and after communication. To provide an infusion device that can mix a drug and a solution in a short time and is inexpensive.

[0009]

[Means and Effects for Solving the Problems] The present invention provides a liquid container in which a dissolving solution or a diluent is stored and a liquid communication port in the upper part, and a liquid container in which a drug is stored in the interior and a drug communication port in the lower part. This infusion device includes a drug container having a drug container, and a stopper that is interposed between the liquid communication port and the drug communication port and can be operated to switch both communication ports into a communicating state.

That is, in the present invention, by switching the stopper, the drug communication port at the lower part of the drug container (the neck of the drug container, the lower part in FIG. 1 of the embodiment) and the upper part of the liquid container (the neck of the drug container, the lower part in FIG. 1 of the embodiment) is connected. Connect the liquid communication port (upper part) to the liquid communication port,
This opens the communication ports of the drug container and the liquid container, thereby allowing the drug and the solution or dilution solution to be mixed to prepare an infusion.

In short, an infusion can be reliably prepared by simply moving the stopper in the rotational or axial direction.
