Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a medical bag having a mouth member attached to which a powdery or liquid drug in a vial can be easily and safely added to a drug solution in the bag.

[0002]

[Prior art]

 The medical solution used for intravenous drip such as conventional medical saline solution and blood (hereinafter referred to as medical solution) is placed in a glass vial equipped with a mouthpiece that can be pierced by an injection needle, and put the mouthpiece near the patient with the mouthpiece down. After setting, the injection needle pierced by the mouth plug and the injection needle pierced by the patient's blood vessel 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 is reduced and the inside of the bottle is in a depressurized state, the drug solution is not injected. Therefore, another injection needle is pierced through the mouth plug and air is reduced as the drug solution decreases. As it is introduced, the inside of the bottle is prevented from being depressurized. However, since outside air enters the sterilized bottle, there is a concern that bacteria and the like may be mixed in the drug solution.

Therefore, recently, a medical bag made of a thermoplastic resin has been generally used instead of the glass bottle.

As the above-mentioned thermoplastic 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. .

[0006]

[Problems to be solved by the device]

 By the way, the use of the synthetic resin medical bag prevents the invasion of various bacteria, but the drug filled in the vial bottle, which is often used for drip, is used by adding it to the drug solution in the medical bag. In this case, as with glass drip bottles, 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drug solution is extracted with a syringe, poured into a vial, the powdery or liquid drug is dissolved, and the drug is withdrawn again with a syringe to give the drug solution in the bag. Since it is added, there is a concern that germs may enter even if a medical bag is used.

As a solution to this, a vial is stored in a capsule, attached to the mouth member, the vial in the capsule is moved downward, and there is no concern that germs will enter. , An infusion container that can be mixed with a drug solution in a flexible container has been proposed (Japanese Patent Laid-Open No. 2-1277).

However, this capsule has a disadvantage that the structure is complicated, the cost is high, the capsule is easy to malfunction, and the capsule and the bag have different sterilization methods and the process is complicated. Further, since rubber is used, there is a possibility that foreign matter may elute or contamination may occur when a needle is stuck into the rubber stopper.

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

[0010]

[Means for Solving the Problems]

 The medical bag of the present invention is a medical bag in which a synthetic resin mouth member that can be connected to a vial is fused to the open end of a bag-shaped synthetic resin sheet,

The mouth member is a tubular mouth member main body whose outer peripheral surface is fused to the opening end of the synthetic resin sheet, and a membrane for closing the lower opening which is the bag side of the mouth member main body.

[0012] The upper part of the mouth member body is fitted from the upper opening, the upper part has a shape connectable to the mouth of the vial, and the locking claw for locking the connected vial mouth is provided inside. A hub that is the vial locking part,

The hub fitted into the mouth member body is prevented from being pushed into the mouth member body at a predetermined position, and when the hub is released, the hub can be further pushed into the mouth member body. A mechanism, a hollow puncture needle that is inserted through the mouth of a vial and a membrane that closes the lower opening that is fixed to the center of the hub along the central axis and has blade edges at both ends,

A means for solving the problem has a seal for sealing the upper opening of the mouth member body.

In addition, a mechanism that prevents the hub from being pushed into the mouth member body at a predetermined position and that can be pushed further by releasing the hub is provided in the concave portion provided on the inner surface of the mouth member body. It is preferable that the convex portion fits into the concave portion provided on the outer side of the hub.

Further, the recess provided on the inner side surface of the mouth member main body may be a recess formed on the inner side surface, or a recess formed by attaching a thin sheet to the outside of the side surface of the hole formed in the side surface. Good.

In addition, the membrane is easy to handle when it is sandwiched between two frame bodies having a hole in the center and the frame bodies are fused and integrated.

[0018]

[Action]

 Since the medical bag of the present invention is provided with the above-described mouth member, when the seal is broken and the vial mouth portion is fitted and connected to the hub upper portion, the upper end of the needle penetrates the vial mouth portion. In this state, the recess on the inner surface of the mouth body is pushed from the outside to release the lock, and by pressing the vial in the vertical direction, the hub is further pushed into the body of the mouth member, and the lower end of the needle penetrates the membrane.

[0019]

【Example】

 1 to 4 show an embodiment of a medical bag according to the present invention, in which reference numeral 1 is a mouth member fused to an open end of a bag-shaped synthetic resin sheet 2.

The mouth member 1 is fitted into a cylindrical mouth member main body 3 having an outer peripheral surface fused to the open end of the bag portion 2 and an upper opening portion of the mouth member main body 3, and the upper portion is a vial bottle. The hub 4 is configured to be connectable to the mouth.

The mouth member main body 3 has a large-diameter cylindrical portion 5 on the outside, and a small-diameter cylindrical portion 6 is concentrically provided inside the lower portion of the large-diameter cylindrical portion 5. The lower ends of the large diameter cylindrical portion 5 and the small diameter cylindrical portion 6 are integrally connected by a bottom plate portion 7.

A first concave portion 8 and a second concave portion 9 for locking the hub 4 are provided to face each other in the vertical middle of the side surface of the large-diameter cylindrical portion 5, and the upper end thereof is obliquely upward and outward. An open extension 10 is integrally formed. Even though the first recess 8 and the second recess 9 are recesses provided on the inner surface of the large-diameter cylindrical portion 5, the sheets 8a and 9a are attached to the outside of the holes formed in the large-diameter cylindrical portion 5. It may be recessed, or the outer periphery of the large-diameter cylindrical portion 5 including the bored holes may be fused and sealed with a bag-shaped synthetic resin sheet 2.

The upper end opening of the small-diameter cylindrical portion 6 which is the opening of the mouth member body 3 on the side of the bag portion 2 is closed by the membrane 11. In this case, if the membrane 11 is directly attached, the membrane 11 is broken and the chemical solution in the bag portion 2 leaks and spreads easily. Therefore, it is easy to handle when the membrane 11 is attached to the frame.

For example, as shown in FIG. 5 to FIG. 7, the membrane 11 is sandwiched between two disk-shaped frame bodies 31, 31 having a hole 31a in the center to fuse and integrate them. Alternatively, when molding the frame body 31 or the frame body in which the frame body 31 and the cylindrical body 32b are integrated, the membrane portion may be integrally formed at the same time. The integrated frame 32 may be fused to the tip of the small-diameter cylindrical portion 6, but it is convenient to attach a cylindrical body 32a that fits into the small-diameter cylindrical portion 6 in a liquid-tight manner if necessary. . A cylindrical member 32b having a size described later is integrally attached to the upper part of the integrated frame member to form a membrane member 33.

The membrane member 33 may be one in which the membrane 11 is sandwiched and integrated in an integrally formed product of the frame body 31 and the cylindrical body 32a or 32b.

The hub 4 has an outer diameter substantially equal to the inner diameter of the large-diameter cylindrical portion 5 of the mouth member body 3, and a hub cylindrical portion 13 having an inner diameter with which the mouth portion 12 a of the vial 12 is fitted, and this hub. A disk-shaped needle support plate 14 integrally provided on the upper end of the cylindrical portion 13 and an upper cylindrical body 32b of the membrane member 33 that is integrally fixed by projecting downward to the center of the needle support plate 14 A hollow puncture needle 17 having an upper cutting edge 17a and a lower cutting edge 17b on both sides, which are fixed to the central axis position of the needle supporting column 15 having an outer diameter equal to the inner diameter, and the outer peripheral upper edge of the hub cylindrical portion 3 and the like. It is composed of a plurality of vial locking parts 18 which are provided with locking claws 18a on their inner sides at appropriate intervals. The inner diameter of the upper cylindrical body 32b of the membrane member 33 may be the same as the outer diameter of the puncture needle 17, and the puncture needle 17 may serve as a stopper of the upper cylindrical body 32b.

On the outer periphery of the hub cylindrical portion 13, there is a ridge 19 for engaging the first concave portion 8 of the large-diameter cylindrical portion 5 of the mouth member body 3 to hold the hub 4 at a predetermined position, and further the hub. A convex portion 20 is formed which engages with the second concave portion 9 when 4 is pushed in.

In order to assemble the mouth member 1, the hub cylindrical portion 13 of the hub 4 is fitted from the upper opening of the mouth member main body 3, the ridge 19 is fitted in the first concave portion 8, and the upper cylindrical body 32b is fitted with the above-mentioned member. It is formed by inserting the needle support column 15 into a plug and then attaching a seal 21 to the expanded portion 10.

At this time, if a shallow guide groove (not shown) that is parallel to the axis and divides the first concave portion 8 into two is provided on the inner peripheral surface of the large-diameter cylindrical portion 5, the mouth member main body 3 and the hub The rotation with 4 is prevented, and the mutual positions in the circumferential direction do not shift and are easy to handle.

In this case, the convex portion 20 is adapted to engage with the second concave portion 9 when further pushed in the state as it is. Further, in the state where the ridge 19 is engaged with the first concave portion 8, the lower cutting edge 17b of the puncture needle 17 is located above the membrane 11 and is released to further push the hub 4 to push the convex portion 20 into the second concave portion. The lower cutting edge 17b is configured to pierce the membrane 11 at the time of being locked to 9. By locking the convex portion 20 in the second concave portion 9, the hub 4 is fixed to the mouth member body 3 at a predetermined position, and the puncture needle 17 maintains the communication state between the vial bottle 12 and the bag portion 2. However, the protrusion 20 and the second recess 9 may not be provided if care is taken to maintain the communication state.

To use the medical bag to which the mouth member 1 is attached, first, as shown in FIGS. 8 to 9, the seal 21 is removed, and the mouth 12 a of the vial 12 is fixed to the vial locking portion 1. 8 and then press it against the surface of the needle support plate 14.

By this operation, the upper blade edge 17a pierces the vial mouth portion 12a. Next, the ridge 19 is pressed from the outside of the first recess 8 to release the engagement between the first recess 8 and the ridge 19, and the vial bottle is further pressed to move the hub cylindrical portion 13 into the large-diameter cylindrical portion 5. Then, the convex portion 20 is fitted into the second concave portion 9. In this case, in the case where the concave portions 8 and 9 are holes, since the thin sheets 8a and 9a are closed, the inside of the mouth member is not contaminated.

By this operation, the needle support column 15 that is the stopper of the upper cylindrical body 32b is inserted further deeply, the lower blade edge 17b penetrates the membrane 11, and the base of the vial locking portion 18 is the large-diameter cylindrical portion 5. Entering inside, the vial mouth portion 12a is locked by the locking claw 18a.

As described above, the mouth member main body 3 and the hub 4, and the hub 4 and the vial bottle are fixed, and the vial bottle 12 and the bag portion 2 are communicated with each other by the puncture needle 17.

Therefore, when the bag 2 is pushed, the drug solution inside enters the vial 12, dissolves the drug in the vial 12, and flows into the bag when the hand is released. By repeating this, the drug in the vial 12 is easily added to the drug solution in the bag 2. Even if the drug solution in the bag portion 2 leaks from between the puncture needle 17 that penetrates the membrane 11 and the membrane 11, the small-diameter cylindrical portion 6 and the lower cylindrical body 32a, and the upper cylindrical body 32b and the needle support column 15 are plugged. Due to the action, the chemical solution does not come out except the membrane member 33.

When instilling the drug to which the drug in the vial is added, the vial 12 does not need to be removed because it is firmly locked to the mouth member 1 and is provided on the mouth member 1 side. The drip is hung by the hanging member 22 and a drip is performed using a conventional spigot (not shown) attached to the lower end of the bag 2.
