Description

TECHNICAL FIELD The present invention relates to a medical container having a port and a sheet releasably attached to the port and containing a medical liquid therein.

2. Description of the Related Art Medical containers such as drug solution containers and infusion containers are provided with ports for discharging stored liquids, co-injecting drugs into the containers, and the like. The port contains a stopper made of an elastic material (rubber material, elastomer material) and capable of being punctured by a medical device (for example, a connecting needle of an infusion set, an injection needle). Also, the port generally has a cap that holds a plug inside. Furthermore, some ports have a protective sheet releasably attached to cover the upper surface of the plug. This protective sheet functions as an indicator to prevent contamination of the plug before use and to confirm whether or not it has been used. Japanese Patent No. 5122878 (Patent Document 1) and Japanese Utility Model Publication No. 3-24186 (Patent Document 2) have been proposed as those having such a peelable sheet. Japanese Patent Laying-Open No. 2018-134315 (Patent Document 3) and Japanese Patent Laying-Open No. 2018-138083 (Patent Document 4) are proposed. Japanese Patent No. 2582134 (Patent Document 5) and Japanese Patent Application Laid-Open No. 2011-78810 (Patent Document 6) propose a structure in which non-peelable plastic film laminates are closely bonded.

Japanese Patent No. 5122878 Japanese Utility Model Publication No. 3-24186 JP 2018-134315 A JP 2018-138083 A Japanese Patent No. 2582134 JP 2011-78810 A

Recently, there have been reports of damage caused by contamination of infusion solutions at multiple hospitals. This is considered to be a crime of piercing the protective sheet with a needle and mixing a foreign substance into the medical container.
Infusions to which a protective sheet is attached are considered by medical professionals to be unused unless the protective sheet is peeled off. For this reason, at the time of administration, confirmation of the presence or absence of needle sticks to the protective sheet and confirmation of the presence or absence of needle sticks to the plug after peeling off the protective sheet are not performed. Further, it is not easy to confirm whether or not the protective sheet has been pricked with a needle. At the time of administration, it is difficult for medical personnel to notice the fact of co-infusion. In this respect, Patent Documents 3 and 4 are effective because it is easy for medical personnel to notice the fact of co-infusion. However, some infusions do not have protective sheets attached, and infusions without protective sheets must be checked carefully.
Moreover, in Patent Document 4, the laminated film of the plastic film is closely bonded and cannot be peeled off. However, in Patent Document 4, it is not necessarily easy to visually recognize the possibility of foreign matter contamination.
In addition, the infusion container may be used to inject other medicines before administration to the patient. Therefore, the discharge port of the infusion container may be punctured multiple times. If multiple punctures are performed, multiple punctures of the same site may result in fluid leakage.
An object of the present invention is to make it easy to confirm when a medical device is punctured by a sheet non-peelably fixed to the upper surface of an elastic member of a port, and to reliably recognize the possibility of mixed injection.

Next, the port section 3 will be explained.
In the medical container 1 of this embodiment, the port portion 3 is a discharge port portion.
The port portion 3 is composed of the tubular opening 21 of the container body 2 described above and a sealing member fixed thereto.
As shown in FIGS. 4 to 6, the sealing member includes a thermoplastic resin cap (annular cap) 5 fixed to a sealing member fixing portion (annular flat portion) 75 of the tubular opening 21, and a cap ( It consists of an elastically deformable sealing member 6 attached to an annular cap 5 and capable of being punctured by a puncturing member.

The elastically deformable sealing member 6 is one that can be punctured by a puncture member (for example, a needle tube for discharging drug solution), and the punctured portion is sealed after the puncture member is removed.
The elastically deformable sealing member 6 is made of an elastic material. As materials for forming the elastically deformable sealing member 6, various rubbers such as silicone rubber, isoprene rubber, butyl rubber, and natural rubber, and various resins such as polyurethane, polyamide elastomer, polybutadiene, and soft vinyl chloride are used.

A plastically deformable sheet 8 is provided on the upper surface of the elastically deformable sealing member 6, as shown in FIGS. The plastically deformable sheet 8 does not have elastic deformation properties, and when a medical device (infusion connecting needle, injection needle, etc.) is punctured, a through hole is formed as shown in FIG. is withdrawn, the through-hole does not restore and becomes a puncture mark 83 . Since part of the upper surface of the elastically deformable sealing member 6 is exposed at the puncture mark 83 , the first color of the elastically deformable sealing member 6 can be directly visually recognized at the puncture mark 83 portion. Then, if the puncture mark is not a normal puncture site, it can be recognized that there is a possibility of foreign matter contamination. In addition, when the puncture mark is a regular mixed injection, puncturing of the medical device to the same site can be avoided.

The plastically deformable sheet 8 is non-peelably fixed to the upper surface of the elastically deformable seal member 6 . Therefore, even if the punctured medical device is removed, the plastically deformable sheet 8 will not come off from the upper surface of the elastically deformable sealing member 6 together with the medical device. Therefore, the puncture marks 83 are reliably left on the upper surface of the elastically deformable sealing member 6 .

Materials for forming the plastically deformable sheet 8 include polyolefin (polyethylene, polypropylene, ethylene-propylene copolymer, mixture of polypropylene and polyethylene or polybutene), polyester (polyethylene terephthalate, polybutylene terephthalate), polyamide, polyvinylidene chloride, and polyvinylidene fluoride. , polyamide, polybutadiene, vinyl chloride, and the like.

Alternatively, the plastically deformable sheet 8 may be formed by laminating it on the upper surface of the elastically deformable sealing member 6 .
As the plastically deformable sheet 8, it is preferable that the puncture mark is enlarged. For example, when a rubber plug is laminated while being compressed in the circumferential direction, the plastically deformable sheet 8 is tensioned by the repulsive force of the rubber, so the puncture mark tends to widen after being pierced. The thickness of the plastically deformable sheet 8 is preferably 20 to 150 μm, particularly preferably 30 to 100 μm. The bending elasticity of the plastically deformable sheet 8 is preferably 100 to 500 MPa.

Furthermore, the plastically deformable sheet 8 has a puncture mark 83 formed by puncturing with a medical device, and the first color of the upper surface of the elastically deformable sealing member 6 can be directly recognized at the puncture mark.
The term "different hues" as used herein refers to different colors, and the term "different hues" refers to differences in lightness and/or saturation and differences in color tones.

In addition, in the medical container 1 of this embodiment, the plastically deformable sheet 8 has transparency, and the upper surface (form of the upper surface) of the elastically deformable sealing member 6 can be visually recognized through the plastically deformable sheet 8. is.
Further, in the medical container 1 of this embodiment, the plastically deformable sheet 8 is transparent, and the first color of the elastically deformable sealing member is the plastically deformable sheet on the upper surface of the elastically deformable sealing member. It differs from the hue or tone of the third color (mixed color) in the laminated state. Therefore, the puncture mark can be easily distinguished from the first color, and the puncture mark can be reliably recognized. The transparency of the plastically deformable sheet 8 is not completely transparent, and preferably has a haze value of 20 to 80%, more preferably 30 to 60%.

As a combination of the first color of the elastically deformable sealing member 6 and the second color of the plastically deformable sheet 8 (combination of different hues or tones), the first color is an expansion color with respect to the second color. preferably. In particular, it is preferred that the first color is an expanding color and the second color is a contracting color. In general, the expansion color refers to a color that makes an object look larger than it actually is, and the contraction color means a color that makes it look smaller than it actually is.
As for the combination of the first color of the elastically deformable sealing member 6 and the second color of the plastically deformable sheet 8 (a combination of different hues or tones), the first color of the elastically deformable sealing member is darker. (dark color), and the second color of the plastically deformable sheet is preferably a light color (light color). In this case, the puncture mark will appear in a light background color (light color) such as white or light gray, and a dark color such as red (dark color), making it easy to grasp the change and visually confirm the puncture mark. Easy.
As for the combination of the first color and the third color (mixed color), a pattern in which one is white or blue and the other is red or yellow is also preferable. The first color of the elastically deformable sealing member is white or gray with a brightness of 3 or more and a saturation of 1 or less, and the second color of the plastically deformable sheet is red, blue, Either greenish or yellowish ones are also preferred.
