Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is equipped with a mouth member that can easily and safely add powdery or liquid drug in a vial to a drug solution in a bag. Regarding medical bags.

[Conventional technology]

The medical solution used for conventional intravenous drip such as physiological saline or blood (hereinafter referred to as the medical solution) is put in a glass bottle equipped with a mouthpiece that can be pierced by an injection needle, and put the mouthpiece near the patient with the mouthpiece down. Set, connect the injection needle pierced in the mouth plug and the injection needle pierced into the patient's blood vessel with a conduit, adjust the height of the bottle,
The liquid medicine is injected into the blood vessel by the head pressure. On this occasion,
When the amount of the drug solution in the bottle decreases and the inside of the bottle is in a depressurized state, the drug solution cannot be injected, so another needle is pierced through the mouth plug,
Air is introduced along with the decrease of the chemical liquid to prevent the pressure in the bottle from being reduced. 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 the glass bottle, a medical bag made of a thermoplastic resin that does not require introduction of outside air has been generally used.

As the above-mentioned thermoplastic resin, soft vinyl chloride, polyethylene, etc. are used, but especially, containing no plasticizer,
Polyethylene is often used because there is no concern that foreign matter will be eluted from the bag into the drug solution.

[Problems to be solved by the device]

By the way, although the invasion of various bacteria is prevented by using the above-mentioned synthetic resin medical bag, the drug filled in the vial bottle which is often used at the time of infusion is added to the drug solution in the medical bag for use. In this case, as in the case of the glass drip bottle, the drug solution is extracted with a syringe, poured into a vial, the powdery or liquid drug is dissolved, and the drug is withdrawn again with a syringe to remove the drug solution in the bag. In this case, there is a concern that various bacteria may enter.

Further, the addition of a drug in a vial using the above syringe is a troublesome task for a busy nurse, and it is necessary to add a drug in a different vial to the drug solution of a large number of medical bags. If it has been a time-consuming task, you must pay the utmost attention.

The present invention has been made in view of the above circumstances, and provides a medical bag provided with a mouth member that can easily and safely add a drug in a vial bottle to a drug solution in the bag without fear of contamination. The purpose is to provide.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the medical bag according to the present invention is a medical bag in which a synthetic resin mouth member connected to the mouth of a vial is fused to the opening end of a bag-shaped synthetic resin sheet. There, the lower part of the mouth member is a cylindrical mouth member main body in which the outer periphery is fused to the opening of the synthetic resin sheet and the upper part fits the vial mouth part, and the vertical direction of the mouth member body. A needle support part formed by partitioning the intermediate part, and a puncture blade which is fixed to the needle support part along the central axis of the mouth member body, is hollow, and has a closed upper end, and the lower part is released. And a puncture needle having a side hole on the side surface above the needle support, a push-down elastic sealing material for sealing the side hole, and an upper opening of the mouth member body. With a seal.

[Action]

Since the medical bag of the present invention has the above-described structure, if the seal is removed and the mouth opening of the mouth member body is fitted into the mouth portion of the vial, the puncture blade of the puncture needle will be the rubber stopper of the vial bottle. The elastic sealing material that seals the side hole with the rubber plug is pushed downward to open the side hole, and the vial and the medical bag are communicated with each other.

〔Example〕

1 to 4 show an embodiment of a medical bag according to the present invention, in which reference numeral 1 is a bag portion.

The bag 1 has a mouth member 2 for connecting a vial fused to one opening, and the other opening sealed with a known rubber stopper 3a used for drip infusion. It is formed of a cylindrical synthetic resin sheet to which the spout 3 is fused. The mouth member 2 and the mouth plug 3 are usually made of the same kind of synthetic resin as the bag 1.

The mouth member 2 has a small-diameter cylindrical portion 4a at the lower portion and a large-diameter cylindrical portion 4b at the upper portion into which the mouth portion 12 of the vial 11 is fitted, and the small-diameter cylindrical portion 4a. Support portion 5 that is integrally attached to the inner peripheral surface of the
And at the central axis position of the mouth member body 4 of the needle support portion 5,
Puncturing blade 6a fixed along the central axis and closed at the tip
And a hollow puncture needle 6 whose lower end is opened.

A side hole 6b is formed in the side portion of the puncture needle 6 near the puncture blade 6a. The side hole 6b is sealed by a detachable elastic sealing member (for example, a rubber band) 7.

In addition, the sterilized mouth member 4 is provided in the opening of the mouth member body 4.
A seal 8 is attached to prevent bacteria from entering the inside of the.

In order to add a drug in the vial bottle 11 and perform infusion using the medical bag to which the mouth member 2 configured as described above is attached, as shown in FIG. The removed vial bottle 11 is press-fitted to the large-diameter cylindrical portion 4b of the mouth member body 4. By this operation, the puncture needle 6 is pierced by the rubber stopper 12a of the mouth 12 of the vial 11, and the elastic sealing material 7 is pushed by the rubber stopper 12a and separated from the side hole 6b. The side hole 6b of the puncture needle 6 that has been pushed down and pierced
Enters the vial 11 and the inside of the bag 1 and the vial 11 are communicated with each other through the side hole 6b.

In this case, since the puncture needle 6 is formed thick,
The vial 11 is held by the cap body 4 by the frictional force between the rubber stopper 12a of the vial and the puncture needle 6, but the vial mouth 12 is attached to the inner peripheral surface of the large-diameter cylindrical portion 4b. If the convex portion 9 that stops is formed, the holding force can be further strengthened.

In the bag portion 1 and the vial bottle 11 which are communicated with each other, the bag portion 1
When is pressed, the drug solution inside enters into the vial 11 to dissolve the drug inside, and when released, it flows into the bag portion 1. By repeating this, the drug in the vial 11 is added to the drug solution in the bag 2.

When the drug added with the drug in the vial is instilled, since the vial 11 is fixed to the mouth member 2, it is hung up without removing it,
This is done using the conventional spout 3 at the lower end of the bag.

[Effects of the Invention] As described above, in the medical bag according to the present invention, a vial is attached to each medical bag, and the drug in the vial is added to the medical bag in a state of being shielded from the outside. , As it is, it can be used for infusion just like a conventional medical bag, so that the nurse's preparation work is reduced, and there is no concern that various bacteria will enter, and the infusion of the drug solution containing the drug in the vial is performed. You can
