Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an infusion bag capable of easily and safely mixing a powdery or liquid drug in a vial with a drug solution in a bag portion.

[Conventional technology]

Conventional medical solutions such as physiological saline and blood, which are used for infusion (hereinafter referred to as drug solutions), are placed in a glass bottle equipped with a mouthpiece that can be pierced by an injection needle, and the mouthpiece is placed near the patient with the mouthpiece down. The injection needle pierced by the mouth plug and the injection needle pierced by the blood vessel of the patient are connected by a conduit, the height of the bottle is adjusted, and the drug solution is injected into the blood vessel by the head pressure. At this time, when the amount of the drug solution in the bottle decreases and the inside of the bottle is in a reduced pressure state,
Since the liquid medicine is no longer injected, another injection needle is pierced through the mouth plug so that air is introduced as the amount of the liquid medicine decreases, so that depressurization of the bottle is prevented. However, since the outside air enters the sterilized bottle, there is a concern that bacteria and the like may be mixed in the drug solution.

Therefore, recently, instead of a glass bottle, an infusion bag made of a thermoplastic resin film that does not require the introduction of outside air has been generally used.

As the above-mentioned plastic resin, soft vinyl chloride, polyethylene and the like are used, but polyethylene which does not contain a plasticizer or the like and has no fear of foreign matter being eluted from the bag into the liquid medicine is often used.

[Problems to be solved by the device]

By the way, although the invasion of various bacteria is prevented by using the synthetic resin infusion bag, when the drug filled in the vial bottle, which is often performed at the time of infusion, is added to the drug solution in the infusion bag and used. Injects the solution into the vial with a syringe to dissolve the powdered or liquid drug, then withdraws it again with the syringe and adds it to the drug in the bag. There is a concern that

In addition, mixing the drug in the vial using the above syringe is a troublesome task for busy nurses, especially when it is necessary to add drugs in different vials to drug solutions in many infusion bags. Must take the utmost care not to mistake the drug,
It is a time-consuming task.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an infusion bag capable of easily and safely mixing the drug in the vial bottle with the drug solution in the bag without fear of contamination. To do.

[Means for Solving the Problems]

In order to achieve the above object, in the infusion bag of the present invention, a synthetic resin mouth member that can be connected to a vial is fused to one opening end of a cylindrical synthetic resin film, and the other opening is formed. , An infusion bag having a spout used for drip fusion fused, wherein the bag portion of the infusion bag is empty on the side on which the mouth member is attached and the other side is filled with the medicinal solution. Is liquid-tightly divided by a detachable clamp, and the mouth member has a tubular mouth member main body whose lower outer periphery is fused to the opening end of the bag portion, and a needle holding portion for vertically partitioning the mouth member main body. A hollow puncture needle which is attached to this needle holding part and whose lower end is opened to the lower part of the needle holding part and whose upper end is a puncture blade pierced by a rubber stopper at the mouth of a vial; And a seal for sealing the upper opening of the mouth member body.

[Action]

Since the infusion bag of the present invention has the above-mentioned structure, the seal is removed, the rubber stopper at the mouth of the vial is pierced through the puncture needle, and then the clip is removed to leave the inside of the bag and the vial bottle. The drug in the vial is dissolved and mixed in the drug solution in the medical bag without any invasion of bacteria from outside.

[Embodiment] FIGS. 1 and 2 show an embodiment of an infusion bag according to the present invention, in which a mouth 22 of a vial 21 is attached to one opening of a cylindrical synthetic resin film. The mouth member 1 is fused, and the well-known mouth stopper 2 to which a rubber stopper 2a used for drip is attached is fused to the other opening to form an infusion bag.

In the bag portion 3 between the mouth member 1 and the mouth plug 2 of the infusion bag,
A clamp 4 for liquid-tightly separating the empty space 3a on the side of the mouth member 1 containing no chemical liquid and the filling portion 3b on the spout 2 side filled with the chemical liquid 23
Is installed.

The clamp 4 is made of synthetic resin and is shown in FIGS.
As shown in (c), just like a clamp such as an ice pillow,
The ridge 5 and the concave groove 6 are provided so as to face each other, one end is connected, and the bag 3 is sandwiched and the other end is tightened.

The mouth member 1 is made of synthetic resin, and the outer periphery is fused to one opening of the bag portion 3 and the lower small diameter portion 7 is formed.
a, and the large diameter part 7 at the top where the vial mouth part 22 is fitted
A needle holding portion 8 that is integral with the mouth member main body 7 that divides the mouth member main body 7 made of b, the large diameter portion 7b, and the small diameter portion 7a, and the needle holding portion 8 that is formed integrally with the needle holding portion 8 The rubber stopper 22 of the vial mouth 22 is opened at one end of the holding portion 8 and has an upper end.
It is composed of a thick puncture needle 9 along the central axis of the mouth member body, which is a puncture blade 9a that pierces a. The upper opening of the mouth member body 7 is sealed by a mouth sealing material 7c.

In order to use the above infusion bag for infusion, the mouth sealant
After removing 7c, the vial bottle 21 is first turned upside down as shown in FIG. 4, the mouth rubber stopper 22a is pressed against the puncture needle 9a, and the puncture needle 9 is pierced through the rubber band 22a. As a result, the vial 21 and the empty portion 3a are communicated with each other. Next, if the clamp 4 is removed, the entire bag portion 3 and the vial bottle 21 are communicated with each other, and if the bag portion 3 is pressed, the drug solution 23 flows into the vial bottle 21 to dissolve the drug and returns to the bag portion 3 when the hand is released. . By repeating this, the drug in the vial is added to and mixed with the drug solution 23. In this case, since the puncture needle 9 is formed thick, the rubber stopper 23a of the vial bottle firmly holds the puncture needle 9 and the vial bottle 21
