DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drug solution container and a drug solution infusion set using the same, and more particularly, to a drug solution container containing a drug solution for infusion or injection, and the mouth of which is lock-connected to the drip set. Liquid injection set.

[0002]

2. Description of the Related Art As a method of communicating a drip set with a drug solution container containing a drug solution such as physiological saline or glucose, for example, as shown in FIG.
By inserting a bottle needle 43 attached to the end of a drip connection pipe 44 of a drip set via a connection portion into a rubber stopper 42 provided in 41, a glass vial serving as a drug solution container is pierced.
Forty chemicals are injected into the human body via the drip communication pipe 44 and the drip set. Since this communication method has a structure in which the bottle needle 43 is merely pierced into the rubber stopper 42, the bottle needle 43 falls off the rubber stopper 42 when liquid leaks from the connection part or when the patient moves during the drip. Or danger. In addition, bottle needle 43
There is a problem in that when the rubber is inserted into the rubber stopper 42, rubber dust is generated, enters the chemical solution container, and is mixed as foreign matter of the chemical solution.

Japanese Patent Laid-Open Publication No. 9-182777 discloses a chemical solution container which solves these problems. The opening portion of the chemical solution container and the end portion of the drip set are formed in a cylindrical opening projecting without using a rubber stopper and a needle. There has been introduced a medical fluid filling bottle that connects a medical fluid container and an infusion set by fitting and screwing together using a part and a tubular body to inject a medical fluid into a human body. Further, the medical fluid discharge opening of the bottle is sealed with a screw-off tab cap which can be opened and opened, and the tab of the bottle which has been screw-sealed is opened by rotating the tab cap by hand. Has become.

[0004]

When a medical fluid must be injected into a blood vessel in a short period of time like a contrast medium, a medical fluid filling bottle having a mouth opened by threading a tab is immediately drip-injected. There is no problem because the drip is started by connecting to the set, but when using general medical solutions such as infusions at general hospitals, a large number of medical fluids with a screwed tab and open mouth are used. Line up the bottles on the desk and leave
The drug solution is infused to the patient by being sequentially connected to an infusion set.
At this time, since the opening of the bottle is exposed to the outside air, there is a risk that bacteria in the air may enter the chemical solution.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to allow bacteria in the air to enter the chemical solution from the mouths of a large number of chemical solution storage containers arranged and left on a desk. The present invention also provides a drug solution infusion set aseptically communicating with the drug solution container and aseptically communicating with the syringe or with the drip set.

[0006]

That is, according to the present invention, there is provided a fragile portion whose mouth portion is integrally formed with a container body and a tab having a thickness larger than the fragile portion, and a portion which enters the inside of the container from the opening portion. A medical solution container provided with a pierceable sheet for sealing a medical solution housed in a container body, wherein the fragile portion is twisted by rotating the tab to open an opening, A medical solution container that is pierced by the puncture needle and communicates with the medical solution stored in the container body.

The present invention is also a lock adapter having a cylindrical shape in which the inner surface of the mouth opening is formed in a luer taper shape in the above-mentioned drug solution container.
Is a chemical solution container provided with a ridge for screwing engagement with a female screw formed at the end of the drip set or at the tip of the syringe. Further, the present invention provides a tubular body provided with a puncture needle at the tip having a tapered shape whose outer peripheral surface can be fitted to the inner peripheral surface of the lock adapter, and an inner surface provided outside the tubular body. A drip set having an end provided with the lock adapter-a connector comprising a rotatable or fixed coupler body formed with a female thread that can be screwed and engaged with a ridge provided on the outer periphery of the end. The puncture needle penetrates the sheet of the drug solution container, the tubular body fits with the inner peripheral surface of the lock adapter of the drug solution container, and the female screw of the coupler body locks the drug solution container. It is a chemical | medical-solution injection | pouring set connected with the chemical | medical solution storage container screwed with the protrusion part formed in the outer periphery of the end part of the adapter.
