Description

[Technical field]

[0001] The present invention relates to a medical container that includes a port and a sheet releasably attached to the port, and that contains a medical liquid therein. [Background technology]

[0002] Medical containers such as drug solution containers and infusion containers are provided with ports for discharging stored liquids and for mixing medicines into the container. The port contains a stopper made of elastic material (rubber material, elastomer material) that can be punctured with a medical tool (e.g., a connecting needle of an infusion set, a syringe needle). In addition, the port generally has a cap that holds the stopper inside. Furthermore, some ports have a protective sheet removably attached to cover the upper surface of the stopper. This protective sheet functions to prevent contamination of the stopper before use and to confirm whether it has been used. As a port provided with such a removably sheet, Japanese Patent No. 5122878 (Patent Document 1) and Japanese Utility Model Publication No. 3-24186 (Patent Document 2) have been proposed, and the applicant of the present application has also proposed Japanese Patent Publication No. 2018-134315 (Patent Document 3) and Japanese Patent Publication No. 2018-138083 (Patent Document 4). Furthermore, Japanese Patent No. 2582134 (Patent Document 5) and JP-A No. 2011-78810 (Patent Document 6) propose a laminate film of a non-peelable plastic film that is tightly bonded.

[0004] Recently, there have been reports in the media of damage caused by foreign objects being mixed into infusions at several hospitals. These crimes are believed to have been committed by puncturing the protective sheet with a needle and mixing foreign objects into medical containers. In the case of an infusion with a protective sheet attached, medical personnel consider the infusion to be unused when the protective sheet of the infusion is not peeled off. For this reason, at the time of administration, confirmation of the presence or absence of needle puncture in the protective sheet and confirmation of the presence or absence of needle puncture in the stopper after the protective sheet is peeled off are not performed. In addition, it is not easy to confirm the presence or absence of needle puncture in the above-mentioned protective sheet. At the time of administration, it is difficult for medical personnel to notice the fact of mixed injection. In this respect, the ones in Patent Document 3 and Patent Document 4 are effective because medical personnel can easily notice the fact of mixed injection. However, there are also infusions without a protective sheet attached, and careful confirmation is required for infusions without a protective sheet attached. In addition, in the case of Patent Document 4, the laminated film of the plastic film is tightly bonded and cannot be peeled off. However, in the case of Patent Document 4, it is not necessarily easy to visually check for the possibility of contamination by foreign matter. In addition, in some cases, other drugs are injected into the infusion container before administration to the patient. For this reason, the outlet port of the infusion container may be punctured multiple times. When multiple punctures are performed at the same site, there is a possibility that liquid leakage may occur. The object of the present invention is to provide a medical container which, when a medical instrument is punctured through a sheet which is inseparably attached to the upper surface of the elastic member of a port, makes it easy to confirm this, ensures that there is a possibility of mixed injection, and also prevents the medical instrument from puncturing the same area in the case of normal mixed injection. [Means for solving the problem]

[0005] The above objectives are achieved by the following: (1) A medical container having a container body, a medical liquid contained in the container body, and a port portion provided in the container body and capable of being punctured by a medical instrument, the port portion includes an elastically deformable seal member having an upper surface with a first color, and a plastically deformable sheet inseparably attached to the upper surface of the elastically deformable seal member, A medical container, wherein the plastically deformable sheet has a second color having a different hue or tone from the first color of the elastically deformable sealing member, and wherein a puncture mark is formed in the plastically deformable sheet by puncturing it with the medical instrument, and wherein the first color of the upper surface of the elastically deformable sealing member is directly visible at the puncture mark.

[0006] (2) The medical container according to (1) above, wherein the plastically deformable sheet has transparency, and the upper surface of the elastically deformable sealing member can be seen through the plastically deformable sheet. (3) A medical container as described in (1) or (2) above, wherein the plastically deformable sheet is transparent, and the first color of the elastically deformable sealing member is different from the hue or tone of a third color when the plastically deformable sheet is laminated on the upper surface of the elastically deformable sealing member. (4) A medical container according to any one of (1) to (3) above, wherein the port portion comprises a tubular opening provided in the container body and a cap housing the elastically deformable sealing member and fixed to the tubular opening, and the plastically deformable sheet is not in contact with the cap. (5) A medical container described in any one of (1) to (4) above, wherein one of the first color of the elastically deformable sealing member and the second color of the plastically deformable sheet is white or blue, and the other is red or yellow. (6) A medical container according to any one of (1) to (5) above, wherein the first color of the elastically deformable sealing member is white or grayish with a brightness of 3 or more and a chroma of 1 or less, and the second color of the plastically deformable sheet is any one of reddish, blued, greend, and yellowd. (7) The medical container according to any one of (1) to (6) above, wherein the port portion is a medical liquid discharge port. (8) The medical container according to any one of (1) to (6) above, wherein the port portion is a mixed injection port. Effect of the Invention

[0007] The medical container of the present invention comprises a container body, a medical liquid contained in the container body, and a port portion provided on the container body and puncturable by a medical instrument. The port portion comprises an elastically deformable sealing member having an upper surface with a first color, and a plastically deformable sheet fixedly attached to the upper surface of the elastically deformable sealing member in a non-removable manner. The plastically deformable sheet has a second color having a different hue or tone from the first color of the elastically deformable sealing member, and a puncture mark is formed on the plastically deformable sheet by puncturing it with the medical instrument, and the first color of the upper surface of the elastically deformable sealing member is directly visible at the puncture mark.

[0008] As a result, the color of the upper surface of the elastically deformable sealing member is exposed at the puncture mark, and further, due to the difference in color between the exposed upper surface of the elastically deformable sealing member and the color of the plastically deformable sheet portion at its peripheral portion, the puncture mark in the plastically deformable sheet can be reliably seen, making it possible to recognize the possibility of mixed injection, and in the case of normal mixed injection, it is possible to avoid puncturing the same area with a medical instrument.

[0010] The medical container of the present invention will be described with reference to the embodiment shown in the drawings. The medical container 1 of the present invention comprises a container body 2, a medical liquid contained in the container body 2, and a port portion 3 provided on the container body 2 and capable of being punctured by a medical instrument. The port portion 3 comprises an elastically deformable sealing member 6 having an upper surface with a first color, and a plastically deformable sheet 8 non-peelably fixed to the upper surface of the elastically deformable sealing member 6. The plastically deformable sheet 8 has a second color having a different hue or tone from the first color of the elastically deformable sealing member 6, and a puncture mark 83 is formed on the plastically deformable sheet 8 by puncturing it with the medical instrument, and the first color of the upper surface of the elastically deformable sealing member 6 is directly visible at the puncture mark 83.

[0011] The medical container 1 in this embodiment comprises a container body 2 having a main body portion 20 and a tubular opening 21 integrally therewith, and the port portion 3 is an outlet port portion 3 which can be punctured by a puncture member, and further, the medical container 1 comprises a drug 7 filled within the container body 2. As shown in Figures 1 to 4, the container body 2 comprises a substantially cylindrical tubular opening 21 having an opening at the upper end, a flattened tubular upper portion 22 that is continuous with the tubular opening 21 and extends downward, a flattened tubular body portion 23 that is continuous with the tubular upper portion 22 and extends downward, and a flattened tubular lower portion 24 that is continuous with the tubular body portion 23 and extends downward.

[0012] Tubular opening 21 is a cylindrical portion that extends a predetermined length with approximately the same inner diameter. In this embodiment, tubular opening 21 constitutes port portion 3 in cooperation with a sealing member described below. Container body 2 also has a closed lower surface portion 28, on which a protruding portion 29 that protrudes downward is formed. Protruding portion 29 functions as an attachment and holding portion for hanging member 4. Hanging member 4 in this embodiment can be bent to hang a medical container.

[0013] The container body 2 of this embodiment has two upper side portions 27a, 27b provided at both ends on the long axis side of the flat cylindrical upper portion 22. The two upper side portions 27a, 27b are abruptly adjacent to each other toward the tubular opening portion 21. Moreover, the upper side portions 27a, 27b are curved portions that protrude outward in a substantially arc shape. Furthermore, the container body 2 has upper central portions 22a, 22b provided on the front and back sides, respectively, of the long axis side (opposite sides of the long axis) of the cylindrical upper portion 22, and the thickness of the upper central portion gradually decreases from the top end to the bottom end.

[0014] The container body 2 also includes a flat tubular body 23 that is continuous with the lower end of the flat tubular upper portion 22 and extends downward. The flat tubular body 23 also includes two body side portions 26a, 26b that are continuous with the lower ends of the upper side portions 27a, 27b and extend downward. The body side portions 26a, 26b are curved portions that protrude outward in a generally arc shape.

[0015] The container body 2 also includes a flat cylindrical lower portion 24 that is continuous with the lower end of the flat cylindrical trunk portion 23 and extends downward. The flat cylindrical lower portion 24 is continuous with two lower side portions 25a, 25b provided at both ends of the long axis of the flat cylindrical lower portion 24, and the lower side portions 25a, 25b are continuous with the lower ends of the trunk portions 26a, 26b and extend to a closed lower surface portion 28. As shown in FIG. 4, the flat cylindrical lower portion 24 is formed so that the width decreases downward (toward the lower surface portion 28) and the thickness also gradually decreases.

[0016] The container body 2 is made of a thermoplastic resin. Examples of the thermoplastic resin that is the material for forming the container body 2 include polyolefins (polyethylene, polypropylene, ethylene-propylene copolymers, mixtures of polypropylene and polyethylene or polybutene), polyesters (polyethylene terephthalate, polybutylene terephthalate), polyamides, polyvinylidene chloride, polyvinylidene fluoride, etc. Among these, polypropylene-based resins that have excellent heat resistance are most preferable.

[0017] The internal volume of the container body 2 is preferably 50 to 1600 ml, and the diameter of the protruding portion 29 is preferably about 2 to 5 mm. The thickness of the main body portion 20 of the container body 2 is preferably 0.1 to 0.5 mm, the width of the main body portion 20 of the container body 2 is preferably 60 to 150 mm, and the length of the main body portion 20 of the container body 2 is preferably 110 to 250 mm.

[0018] Next, the port section 3 will be described. In the medical container 1 of this embodiment, the port portion 3 is a discharge port portion. The port portion 3 is constituted by the tubular opening 21 of the container body 2 described above and a sealing member fixed to the tubular opening 21. As shown in Figures 4 to 6, the sealing member consists of a cap (annular cap) 5 made of thermoplastic resin fixed to the sealing member fixing portion (annular flat portion) 75 of the tubular opening 21, and an elastically deformable sealing member 6 that is attached to the cap (annular cap) 5 and can be punctured by the puncture member.

[0019] The elastically deformable sealing member 6 is one that can be punctured by a puncture member (eg, a needle tube for discharging a medical solution), and further, is one that seals the puncture portion after the puncture member is removed. The elastically deformable seal member 6 is made of an elastic material. Examples of materials that can be used to form the elastically deformable seal member 6 include various rubbers such as silicone rubber, isoprene rubber, butyl rubber, and natural rubber, and various resins such as polyurethane, polyamide elastomer, polybutadiene, and soft polyvinyl chloride.

[0020] As shown in Figs. 5 to 8, the upper surface of the elastically deformable seal member 6 is provided with a plastically deformable sheet 8 that is fixed in an inseparable manner. The plastically deformable sheet 8 does not have elastic deformability, and when a medical tool (such as an infusion connection needle or an injection needle) is punctured, a through hole is formed as shown in Fig. 8. When the punctured medical tool is removed, the through hole does not return to its original state and becomes a puncture mark 83. Since a part of the upper surface of the elastically deformable seal member 6 is exposed at the puncture mark 83, the first color of the elastically deformable seal member 6 can be directly seen at the puncture mark 83. If the puncture mark is not a normal puncture site, it can be recognized that there is a possibility of foreign matter being mixed in. If the puncture mark is a normal mixed injection, it is possible to avoid puncturing the same site with a medical tool.

[0021] The plastically deformable sheet 8 is fixedly attached in an unpeeling manner to the upper surface of the elastically deformable sealing member 6. Therefore, even when the punctured medical instrument 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 instrument. Therefore, the puncture mark 83 remains reliably on the upper surface of the elastically deformable sealing member 6.

[0022] Materials for forming the plastically deformable sheet 8 include polyolefins (polyethylene, polypropylene, ethylene-propylene copolymer, mixtures of polypropylene and polyethylene or polybutene), polyesters (polyethylene terephthalate, polybutylene terephthalate), polyamides, polyvinylidene chloride, polyvinylidene fluoride, polyamides, polybutadiene, vinyl chloride, etc. It is preferable that the material has thermal adhesiveness with the material for forming the elastically deformable seal member 6. The plastically deformable sheet 8 may be formed by laminating it on the upper surface of the elastically deformable seal member 6. The plastically deformable sheet 8 is preferably one that leaves a large puncture mark. For example, when a rubber stopper is laminated while being compressed in the circumferential direction, tension is applied to the plastically deformable sheet 8 by the repulsive force of the rubber, so that the puncture mark tends to widen after puncture. The thickness of the plastically deformable sheet 8 is preferably 20 to 150 μm, and more preferably 30 to 100 μm. The bending elasticity of the plastically deformable sheet 8 is preferably 100 to 500 MPa.

[0023] At least the upper surface of the elastically deformable sealing member 6 has a first color. The plastically deformable sheet 8 has a second color having a different hue or tone from the first color of the elastically deformable sealing member 6. Furthermore, a puncture mark 83 is formed in the plastically deformable sheet 8 by puncturing it with a medical instrument, and the first color of the upper surface of the elastically deformable sealing member 6 can be directly seen at the puncture mark. Different hues here refer to different colors, and different tones refer to different lightness and / or saturation, or different color tones.

[0024] Furthermore, in the medical container 1 of this embodiment, the plastically deformable sheet 8 has transparency, and the upper surface (shape of the upper surface) of the elastically deformable sealing member 6 can be seen through the plastically deformable sheet 8. Furthermore, in the medical container 1 of this embodiment, the plastically deformable sheet 8 has transparency, and the first color of the elastically deformable sealing member is different from the hue or tone of the third color (mixed color) in a state in which the plastically deformable sheet is laminated on the upper surface of the elastically deformable sealing member. This makes it easy to distinguish the first color from the puncture mark, and the puncture mark can be recognized reliably. The transparency of the plastically deformable sheet 8 is not completely transparent, and the haze value is preferably 20 to 80%, and particularly preferably 30 to 60%.

[0025] 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), it is preferable that the first color is an expanding color compared to the second color. In particular, it is preferable that the first color is an expanding color and the second color is a contracting color. Note that an expanding color generally refers to a color that makes something appear larger than it actually is, and a contracting color conversely refers to a color that makes something appear smaller than it actually is. As a combination (a combination of different hues or tones) of the first color of the elastically deformable sealing member 6 and the second color of the plastically deformable sheet 8, it is preferable that the first color of the elastically deformable sealing member is a dark color (dark color system) and the second color of the plastically deformable sheet is a light color (light color system). In this case, the puncture mark will have a dark color (dark color system) such as red on a light background color (light color system) such as white or light gray, making it easy to grasp the change and to visually recognize the puncture mark. Also, as a combination of the above-mentioned first color and the above-mentioned third color (mixed color), one is preferably white or blue and the other is preferably red or yellow.Also, it is preferable that the first color of the elastically deformable sealing member is white or gray with a brightness of 3 or more and a chroma of 1 or less, and the second color of the plastically deformable sheet is any of red, blue, green, and yellow. In any case, it is preferable that both the first color of the elastically deformable sealing member 6 and the second color of the plastically deformable sheet 8 are not black.

[0026] In the medical container 1 of this embodiment, the elastically deformable seal member 6 includes a substantially cylindrical seal member main body 61, a side portion (annular side portion) 62 provided to enclose the side surface of the seal member main body 61, and a connecting portion (annular connecting portion) 64 connecting the center portions of the seal member main body 61 and the side portion (annular side portion) 62, as shown in Fig. 4 and Fig. 5. Therefore, the elastically deformable seal member 6 includes a recess (annular recess) formed by the upper surface of the connecting portion (annular connecting portion) 64, the upper portion 62a of the side portion (annular side portion) 62, and the upper portion of the seal member main body 61. In addition, the elastically deformable seal member 6 includes a recess (annular recess) formed by the lower surface of the connecting portion (annular connecting portion) 64, the lower portion 62b of the side portion (annular side portion) 62, and the lower portion of the seal member main body 61, as shown in Fig. 5.

[0027] The sealing member main body 61 is formed in a substantially cylindrical shape, and has recesses 66a, 66b, and 66c on the upper surface thereof as puncture indicators, as shown in Figs. 4 and 5. In the medical container 1 of this embodiment, the plastically deformable sheet 8 has transparency, and the recesses 66a, 66b, and 66c formed on the upper surface of the elastically deformable sealing member can be seen through the plastically deformable sheet 8. Therefore, the plastically deformable sheet 8 does not hinder the puncture of the medical instrument into the recesses 66a, 66b, and 66c. Furthermore, in the medical container 1 of this embodiment, as shown in Fig. 7, the plastically deformable sheet 8 is in close contact with the upper surface of the elastically deformable sealing member 6 without any gaps. Therefore, the plastically deformable sheet 8 has recesses 82a, 82b, and 82c corresponding to the recesses 66a, 66b, and 66c, as shown in Figs. 6 and 7.

[0028] The lower surface of the elastically deformable seal member 6 is provided with a skirt-shaped protrusion 65 that is formed on the periphery of the lower surface and becomes thinner toward the end. As shown in Fig. 5, this skirt-shaped protrusion 65 penetrates into the tubular opening 21 (inside the small-diameter tip portion 74 of the cylindrical portion 73). As shown in Fig. 5, the skirt-shaped protrusion 65 becomes thinner toward the lower end and the inner diameter increases. For this reason, the inner surface of the skirt-shaped protrusion 65 is an inclined surface that increases in diameter toward the lower end (specifically, a curved inclined surface that increases in diameter toward the lower end).

[0029] The port portion 3 (sealing member) is provided with a cap (annular cap) 5 made of a thermoplastic resin that is fixed to a sealing member fixing portion (annular flat portion) 75 of the tubular opening 21 . The cap (annular cap) 5 comprises a cylindrical main body 51 having an elastically deformable sealing member mounting portion, a protrusion (annular protrusion) 52 protruding outward from the lower end side of the cylindrical main body 51, and a fusion protrusion 55 protruding downward from the underside of the protrusion (annular protrusion) 52.

[0030] As shown in FIG. 5, the lower surfaces of the cylindrical main body portion 51 and the protrusion portion (annular protrusion portion) 52 of the cap (annular cap) 5 face the upper surface annular flat portion of the sealing member fixing portion 75 of the flange portion 71, and the fusion protrusion portion 55 is melted and fixed to the upper surface annular flat portion (sealing member fixing portion) 75 of the flange portion 71. As shown in Figs. 5 to 8, the cap (annular cap) 5 has an opening, and houses the elastically deformable seal member 6 with the upper surface of the main body 61 of the elastically deformable seal member 6 exposed at the opening.

[0031] The cap (annular cap) 5 includes a cylindrical main body 51, an inner cylindrical portion 53 that is arranged concentrically with the cylindrical main body 51 and connected at the upper portion by a connecting portion 54, and a protrusion (annular protrusion) 52 that protrudes outward from the outer surface of the lower end of the cylindrical main body 51. A wavy protrusion 58 is formed on the upper surface of the connecting portion 54, and is formed in an annular shape in this embodiment.

[0032] The protrusion (annular protrusion) 52 has a fusion protrusion 55 extending downward from a position slightly inside the outer edge. In this embodiment, the fusion protrusion 55 is an annular rib, and both the inner and outer diameters decrease toward the lower end. Furthermore, in this embodiment, as shown in Fig. 5, the lower end of the fusion protrusion 55 is an annular flat surface. The cylindrical main body 51 extends in a predetermined longitudinal direction and is substantially cylindrical.

[0033] The cap (annular cap) is made of a thermoplastic resin. Examples of the thermoplastic resin that is the material for forming the cap (annular cap) include polyolefin (polyethylene, polypropylene, ethylene-propylene copolymer, mixture of polypropylene and polyethylene or polybutene), polyester (polyethylene terephthalate, polybutylene terephthalate), polyamide, polyvinylidene chloride, polyvinylidene fluoride, etc. In addition, the cap (annular cap) is preferably made of a material that is highly compatible with the material for forming the tubular opening 21 (in this embodiment, the container body 2), and more preferably, the same or similar resin. Furthermore, the material for forming the cap (annular cap) is preferably made of a material that has a lower melting point than the material for forming the tubular opening 21 (in this embodiment, the container body 2).

[0034] In this elastically deformable seal member 6, the outer diameter of the upper part of the substantially cylindrical seal member main body 61 is substantially the same as the diameter (inner diameter of the inner cylinder portion 53) of the opening of the above-mentioned cap (annular cap) 5. The upper part of the seal member main body 61 advances into the opening of the cap (annular cap) 5, as shown in Fig. 5. In addition, in the elastically deformable seal member 6 of this embodiment, the upper part (annular upper part) 62a of the side part (annular side part) 62 is housed in the recess (annular recess) of the cap (annular cap) 5, as shown in Fig. 5.

[0035] Furthermore, the lower part (annular lower part) 62b of the side part (annular side part) 62 of the elastically deformable seal member 6 is housed between the cylindrical main body part 51 of the cap (annular cap) 5 and the small diameter tip part 74 of the main body part 20, as shown in Fig. 5. As shown in Fig. 5, the lower end of the inner cylindrical part 53 of the cap (annular cap) 5 and the upper end of the small diameter tip part 74 of the main body part 20 face each other, and the connecting part (annular connecting part) 64 of the elastically deformable seal member 6 is clamped by the inner cylindrical part 53 of the cap (annular cap) 5 and the small diameter tip part 74 of the main body part 20. This provides a liquid-tight seal between the tubular opening part 21 and the sealing member.

[0036] In the medical container 1 of this embodiment, as described above, the port portion 3 includes the tubular opening 21 provided in the container body 2, and the cap 5 that houses the elastically deformable seal member 6 and is fixed to the tubular opening 21, and the plastically deformable sheet 8 is not in contact with the cap 5. Therefore, when the cap 5 presses the elastically deformable seal member 6, the plastically deformable sheet 8 does not become an obstacle, and the plastically deformable sheet 8 is not deformed by the cap 5. In addition, in the medical container 1 of this embodiment, the elastically deformable seal member 6 is exposed in a ring shape on the outside of the outer edge 81 of the plastically deformable sheet 8, and the color (first color) of the elastically deformable seal member 6 itself can be visually recognized in this portion. By comparing the color in this portion with the color of the puncture mark 83, it is easy to recognize that the elastically deformable seal member 6 is exposed to the puncture mark 83.

[0037] The medical container of the present invention may be a soft bag-type medical container 100 as shown in FIG. In the medical container 100 of this embodiment, a discharge port 3 made of a tubular opening 21 and a sealing member is used. In the medical container 100 of this embodiment, a mixture port 104 made of a tubular opening 21 and a sealing member is used. The discharge port 3 and the mixture port 104 are provided with the above-mentioned elastically deformable seal member 6, and further provided with a plastically deformable sheet 8 fixed to the upper surface (front surface) of the above-mentioned elastically deformable seal member 6 in a non-peeling manner.

[0038] The sealing members of the ports 3 and 104 are substantially the same as those of the medical container 1 described above. In addition, the medical container 100 of this embodiment uses a soft container 102. The tubular opening 21 is formed of a separate member from the soft container 102, and is fixed to the soft container 102 by fastening parts 127, 128.

[0039] The soft container (container body) 102 of this embodiment is formed of a sheet-like cylindrical body. The container body 102 is formed with a partition 109 that divides the internal storage section and constitutes a releasable partition, and is divided into a first medicinal liquid chamber 121 and a second medicinal liquid chamber 122. In this medical container 100, a medicine discharge port 3 is attached to the first medicinal liquid chamber 121 of the container body 102. The first medicinal liquid chamber 121 contains a first medicinal liquid, and the second medicinal liquid chamber 122 contains a second medicinal liquid. The container body 102 of this embodiment is provided with an upper seal portion 105, a lower seal portion 106, and side seal portions 107 and 108.

[0040] The partition 109 has a peelable partition weak seal 109a that crosses the entire container body 102 in the lateral direction, and a substantially unpeelable strong seal 109b that is provided within branched portions at both ends of the weak seal 109a. The volume of the medical container 100 varies depending on the type of drug contained therein, but generally, the volume of the first drug liquid chamber is preferably about 50 to 5000 ml, and the volume of the second drug liquid chamber is preferably about 50 to 5000 ml.

[0041] The medicine contained in each of the drug liquid chambers may be a drug liquid, a powder, or the like. In particular, in the medical container of the present invention, the first drug liquid is preferably a drug liquid. The second drug liquid may be either a drug liquid or a powder. Preferably, it is a drug liquid. Combinations of the first drug liquid and the second drug liquid include, for example, a combination of an amino acid electrolyte solution and a glucose solution, a glucose solution and a sodium bicarbonate solution, and the like.

[0042] The medical container 100 of this embodiment is provided with a peelable communication-impeding weak seal portion 110 that inhibits communication between the discharge port 3 and the inside of the container body 102. As a result, the discharge port 3 communicates with the empty chamber 123 in the container body 102, but does not communicate with the first drug solution chamber 121. The above-mentioned weak seal portions 109a, 110 are formed by heat sealing (thermal fusion, high-frequency fusion, ultrasonic fusion, etc.) a sheet material into a strip shape.
