And a needle tube entry inhibiting portion 4 that inhibits entry of the drug ejection needle tube into the cylindrical portion 31a when the portion 31c is not broken.
The discharge port 3 of this embodiment is a non-communication discharge port. As shown in FIG. 3, the discharge port 3 does not communicate with the inside of the medicine chamber 11 when not broken.
A medical container 1 according to this embodiment is formed of a flexible material, and includes a container body 2 having a medicine chamber 11 serving as a medicine storage portion therein, and a medicine discharge port 3 attached to the medicine chamber 11 of the container body 2. And a medicine-filled medical container comprising a medicine solution filled in the medicine chamber 11.
As shown in FIG. 1, seal portions 5 and 6 are provided on one end side and the other end side of the container body 2.

The container body 2 of the medical container 1 is formed of a soft synthetic resin. The container body 2 is preferably formed into a cylindrical shape by an inflation molding method. The container body 2 may be manufactured by various methods such as a blow molding method and a coextrusion inflation method.
The container body 2 preferably has a water vapor barrier property. As the degree of water vapor barrier property, the water vapor permeability is preferably 50 g / m ² · 24 hrs · 40 ° C. · 90% RH or less, more preferably 10 g / m ² · 24 hrs · 40 ° C. · 90% RH or less. More preferably, it is 1 g / m ² · 24 hrs · 40 ° C. · 90% RH or less. This water vapor permeability is measured by the method described in JISK7129 (Method A).
As described above, the container main body 2 has the water vapor barrier property, so that the evaporation of moisture from the inside of the medical container 1 can be prevented. As a result, it is possible to prevent reduction and concentration of the medicine (specifically, chemical solution) to be filled. Moreover, the invasion of water vapor from the outside of the medical container 1 can be prevented.

Examples of the material for forming the container body 2 include various types such as polyethylene (PE), polypropylene (PP), polybutadiene, polyolefin such as ethylene-vinyl acetate copolymer (EVA), olefin elastomer, and styrene elastomer. Thermoplastic elastomers or those arbitrarily combined (blend resins, polymer alloys, laminates, etc.) can be mentioned. And it is preferable that the resin material to be used has the heat resistance and water resistance which can endure high pressure steam sterilization (autoclave sterilization).
Moreover, when polyolefin is contained as a material for forming the container body, the usefulness of the present invention is great. Therefore, in this invention, it is preferable that polyolefin is included as a forming material of the container main body 2. As a material for forming the container main body 2, particularly preferable are polyethylene, polypropylene, styrene-based thermoplastic elastomers such as styrene-butadiene copolymers and styrene-ethylene-butylene-styrene block copolymers, or ethylene-propylene copolymers. And a soft resin obtained by blending and softening an olefin-based thermoplastic elastomer such as an ethylene-butene copolymer or a propylene-α-olefin copolymer. This material is preferable in that it has high strength and high flexibility, high heat resistance (particularly heat resistance during sterilization), high water resistance, excellent workability, and reduction in production cost.

  Further, the container body may have a single layer structure (single layer body) made of the material as described above, or a multilayer in which a plurality of layers (particularly layers of different materials) are stacked for various purposes. A laminated body may be sufficient. In the case of a multilayer laminate, a plurality of resin layers may be stacked, or a metal layer may be stacked on at least one resin layer. In the case where a plurality of resin layers are stacked, the advantages of the respective resins can be provided together. For example, the impact resistance of the container body 2 can be improved or anti-blocking properties can be imparted. Further, in the case of a metal layer, the gas barrier property of the container body 2 can be improved. For example, when a film such as an aluminum foil is laminated, the gas barrier property can be improved and the light shielding property can be imparted. In addition, when a layer made of an oxide such as titanium oxide, aluminum oxide, or silicon oxide is formed, the transparency of the container body 2 can be maintained while the gas barrier property is improved, and the internal visibility is ensured. Can do. In addition, when the container main body 2 is a multilayer laminated body, it is preferable that the material which forms the inner surface part is the material mentioned above.

The thickness of the sheet material constituting the container body 2 is appropriately determined according to the layer configuration and the characteristics of the material used (flexibility, strength, water vapor permeability, heat resistance, etc.), and is not particularly limited. However, usually, it is preferably about 100 to 500 μm, and more preferably about 200 to 360 μm.
Moreover, although the volume of the medical container 1 changes with kinds etc. of the chemical | medical agent accommodated in an inside, it is preferable normally that the volume of a chemical | medical agent chamber is about 50-5000 ml.
The medicine discharge port 3 is for discharging the medicine (chemical solution) filled in the container body 2.

  In this embodiment, an appropriate amount of medicine 8 is accommodated in the discharge port 3 as shown in FIGS. Moreover, it is preferable that the formation part of the chemical | medical agent storage part 34 of the discharge port 3 is transparently formed so that an internal chemical | medical agent can be visually observed. The medicine to be stored may be any powder, granule or other solid form or liquid form. Drugs are formulated and dissolved in infusions. For example, antibiotics, vitamins (general vitamins), various amino acids, antithrombotics such as heparin, insulin, antitumor agents, analgesics, cardiotonics, statics Note: Anesthetic agents, anti-Parkinson agents, ulcer treatment agents, corticosteroid agents, arrhythmia agents, correction electrolytes, antiviral agents, immunostimulants, and the like. Moreover, although the cylindrical part 31a of the discharge port 3 may be a normal pressure, it is good also as a pressure reduction or a vacuum state. As described above, when the medicine container is in a reduced pressure or vacuum state, the effect of preventing the degradation and degradation of the medicine is improved, and the infusate is sucked when the breakable portion 31c breaks, so that the tubular shape can be more quickly formed. It can introduce into the part 31a.

As shown in FIGS. 2, 3, and 4, the discharge port 3 is fixed to the drug chamber 11 and includes a port main body portion 31 including a flow restricting portion that can be broken, and the other end side of the port main body portion 31. A discharge port 33 having a sealing portion 32 capable of connecting a closed medicine discharge needle tube and a needle tube intrusion inhibiting portion 4 provided in the port main body portion 31 are provided.
The port body portion 31 closes the tubular portion 31a and one end side of the tubular portion 31a and breaks the first drug chamber 11 of the container body 2 and the inside of the tubular portion 31a by being broken. A flow restricting portion including an operation portion 31b for performing a breaking operation of the breakable portion 31c and the breakable portion 31c is provided.
The breakable portion 31c is a portion where a wedge-shaped annular recess is formed, and is thinner than other portions. For this reason, the breakable portion 31c is weaker than other portions, and by pushing the operation portion 31b from the outside of the bag, the breakable portion 31c is broken at the breakable portion 31c. Separated from the part 31a. And it is preferable that the operation part 31b to isolate | separate is hollow so that it may show in figure. By doing in this way, the breakable part 31c becomes a state without uneven thickness. The distance between the inner upper surface of the tubular portion 31a and the breakable portion 31c is preferably 1 to 2 mm.

Furthermore, you may form this operation part 31b in the color discriminable with respect to the chemical | medical solution after mixing a chemical | medical agent. It can be easily identified from the chemical solution, and the remaining amount of the chemical solution can be easily confirmed because it floats on the chemical surface. The color distinguishable with respect to the drug solution after mixing the drug differs depending on the drug solution and the drug used, and is not unique. For example, if the color of the drug solution after mixing the drug is yellow, If red (red, blue, green, black) is red, it is assumed to be other than red (for example, yellow, blue, green, black). In addition, when the color of the chemical | medical solution after a chemical | medical agent mixing is colorless, as long as it is colored, what kind of color may be sufficient.
The sealing portion 32 is formed of an elastic member that seals the rear end opening of the cylindrical portion and can be pierced by the needle tube for discharging the medicine. In this embodiment, the port main body portion 31 is formed by the cap portion 33a. The discharge port 33 is configured by being fixed to the rear end.

In the medical container 1 of this embodiment, the needle tube entry inhibiting portion 4 is accommodated in the discharge port 3. As shown in FIG. 3, the needle tube intrusion inhibiting unit 4 in this embodiment includes a distal end portion 41 that can abut on the operation portion 31 b (the bottom surface of the bottom of the operation portion) and a base on which the distal end of the drug discharge needle tube can abut. It has an end portion 42 and a connecting portion 43 that connects the distal end portion 41 and the proximal end portion 42.
In the state where the breakable portion of the flow restricting portion is not broken (the state shown in FIG. 3), when the medicine discharge needle tube is punctured into the sealing portion 32, the distal end of the needle is the proximal end portion of the needle tube entry inhibiting portion 4 Even if the needle tube intrusion inhibiting part 4 is moved upward and the tip part 41 is brought into contact with the operation part 31b, it cannot move any further even if it is brought into contact with 42 and further pressed. Further, the needle tube intrusion inhibiting portion 4 of this example is slightly movable in the cylindrical portion, but in the state where the proximal end portion 42 is in contact with the sealing portion 32, the distal end portion 41 and the operation portion 31b. There may be almost no distance between (the bottom surface of the bottom of the operation unit) and it cannot be moved substantially.
And an operator recognizes that the distribution control part is unbroken from the needle tube for medicine discharge being in an unpuncturable state.
The length of puncture of the discharge port of the drug discharge needle tube when the breakable portion of the flow restricting portion is not broken (the state shown in FIG. 3) is such that the opening of the drug discharge needle tube does not communicate with the inside of the discharge port. It is preferable. Therefore, it is preferable that the movable distance in the discharge port of the needle tube entry inhibiting portion 4 is 5 mm or less.

In the needle tube entry inhibiting portion 4 of this example, the tip portion 41 is hemispherical. By doing in this way, it becomes the shape which is hard to be caught in the inner edge part after the fracture | rupture of a breakable part. Further, the needle tube entry inhibiting portion 4 includes a wing portion 46 that is provided on the side surface of the connection portion 43, extends to the proximal end side from an appropriate position of the connection portion 43, and has a lower end continuous with the peripheral edge of the proximal end portion 42. . By providing such a wing portion, the base end portion 42 is prevented from being caught by the inner edge portion after the breakable portion of the breakable portion. In this example, the wing part 46 extends from the tip part 41.
Further, the needle tube intrusion inhibiting portion 4 is not limited to the above type, and for example, is a cylindrical type with a lower end portion closed like the needle tube intrusion inhibiting portion 4a shown in FIG. Also good. In the case of such a type of needle tube entry inhibiting portion 4a, it is preferable that a large number of windows are formed on the side surface. By doing in this way, mixing with the chemical | medical solution with which the chemical | medical agent chamber 11 of the container main body 2 of the chemical | medical agent body located in the needle tube penetration | inhibition part 4a was filled becomes favorable. In this type of needle tube entry inhibiting portion 4a, the distal end portion 41 formed by the upper end contacts the operation portion 31b, the proximal end portion 42 formed by the bottom surface contacts the distal end of the drug discharge needle tube, and the side surface portion is the distal end. A connecting portion 43 that connects the portion 41 and the base end portion 42 is formed. The cross-sectional shape of the cylindrical type as described above may be any of a circle (columnar shape, cylindrical shape) including an ellipse, a polygonal shape (for example, a triangle, a quadrangle), and the like.

And the needle tube penetration | inhibition inhibiting part 4a of the example mentioned above can flow out from a discharge port after the fracture | rupture of the breakable part of a distribution control part. However, it is not limited to such a thing.
For example, as in the discharge port 36 of the example shown in FIG. 6, the needle tube entry inhibiting portion does not flow out from the port main body portion 31 as long as it does not inhibit the puncture of the drug discharge needle tube after the breakable portion is broken. It may be. In the discharge port 36, the inner diameter of the port main body portion 31 near the breakable portion is smaller than the outer diameter of the proximal end portion 42 of the needle tube entry inhibiting portion 4b. For this reason, even after the breakable portion of the flow restricting portion is broken, even if the needle tube penetration inhibiting portion 4b is lifted by buoyancy, the needle tube penetration inhibiting portion is formed on the upper portion (the portion that was the breakable portion) of the broken tubular portion 31a. The base end part 42 of 4b contacts and is locked, and does not flow out of the cylindrical part.
In the case of such a type, it is preferable that the needle tube entry inhibiting portion 4b has an opening at the base end portion 42 as shown in FIG. In the needle tube entry inhibiting portion 4b, the opening is configured by a plurality of slits 44a extending inward from the periphery of the base end portion. Note that the opening may be a through-hole provided in the base end portion 42 as in the needle tube entry inhibition portion 4c shown in FIG. In this example, a plurality of (for example, 2 to 8, specifically, four) through holes 45a are provided.
Also in this type of needle tube entry inhibiting portion 4b, the tip portion 41 is preferably hemispherical. Moreover, although a wing | blade part may be provided, it is preferable not to provide.

  Furthermore, although the needle tube penetration | inhibition inhibiting part 4 of the example mentioned above is a thing isolate | separated from the operation part 31b, it is not limited to such a thing. For example, like the discharge port 53 shown in FIG. 9, the distal end portion 64a of the needle tube entry inhibiting portion 64 may be fixed to the operation portion 31b. In the discharge port 53, after the breakable portion of the flow restricting portion is broken, the needle tube entry inhibiting portion 64 is floated together with the operation portion 31b and flows out from the tubular portion. In the case where such a needle tube intrusion inhibiting portion is integrated with the operation portion, the needle tube intrusion inhibiting portion needs to be in a form that does not hinder the breaking operation in the operation portion. Also in the needle tube penetration inhibiting part 64 of this example, like the needle tube penetration inhibiting part 4 described above, the needle tube penetration inhibiting part 64 is provided on the side surface of the connection part 43, extends from the appropriate position of the connection part 43 to the proximal end side, and the lower end is the proximal end part. It is preferable to provide a wing portion that is continuous with the peripheral edge of 42.

Further, even in this type of discharge port, for example, as long as the discharge port 63 shown in FIG. 10 does not hinder the puncture of the drug discharge needle tube after the breakable portion is broken, the needle tube entry blocking portion May not flow out of the port body 31. In the discharge port 63, the inner diameter of the port main body 31 in the vicinity of the breakable portion is smaller than the outer diameter of the proximal end portion 64 b of the needle tube entry inhibiting portion 64. For this reason, even after the breakable portion of the flow restricting portion breaks, even if the needle tube intrusion inhibiting portion 64 rises due to buoyancy together with the operation portion 31b, the upper portion of the broken tubular portion 31a (the portion that was the breakable portion) The proximal end portion 64b of the needle tube entry inhibiting portion 64 comes into contact with and is locked and does not flow out of the cylindrical portion.
In the case of such a type, it is preferable to have an opening at the base end portion 64b in order to ensure the flow of the chemical solution. As the opening, those shown in FIGS. 7 and 8 and described above are preferable.

  Hard or semi-rigid resin is suitable as a material for forming the cylindrical portion, the needle tube intrusion inhibiting portion, and the cap portion in all the embodiments described above. As a material for forming the cylindrical portion, a material that can be fused to the container body by ultrasonic fusion, heat sealing, or the like is preferable. Moreover, as a forming material of the cap part 33a of the discharge port 33, a hard or semi-hard resin is suitable. Further, the material for forming the cap portion 33a is preferably a material that can be fused to the port body portion 31 by ultrasonic fusion, high frequency fusion, or the like. In addition, as shown in FIG. 3, the port main body portion 31 preferably includes a flange portion 31 d having an annular recess that accommodates the tip portion of the cap portion at the rear end. The cap portion 33a includes a flange portion 33b that comes into contact with the flange portion 31d, and a tip portion 33c that is accommodated in the annular recess of the cylindrical portion. And the port main-body part 31 and the cap part 33a are fixed liquid-tightly in the contact surface of both flange parts.

  Further, the first stress applying part 21 and the second stress applying part 22 are formed slightly apart between the first stress applying part 21 and the second stress applying part 22. Thus, the first stress applying part 21 and the second stress applying part 22 are not so far apart. For this reason, even if the space between the first stress applying portion 21 and the second stress applying portion 22 is pressed when being fixed to the container body 2, the first stress applying portion 21 and the second stress applying portion 22 are allowed. The amount of deformation is small and there is no possibility that the breakable portion 15 will break.

In addition, the whole or part of the flat surface portion 22 b of the second stress applying portion 22 is joined to the inner surface of the sheet of the container body 2 to form the second fixing portion. For this reason, the first stress applying part and the second stress applying part follow the spread between the first stress applying part and the fixed part of the second stress applying part of the soft bag when the drug chamber is pressed. It spreads, and a breakable portion, which will be described later, is opened and broken on one sheet side and the other sheet side.
The bonding between the flat surface portion 21b of the first stress applying portion 21 and the flat surface portion 22b of the second stress applying portion 22 and the inner surface of each sheet of the container body 2 is performed by ultrasonic fusion, high frequency fusion, thermal fusion, or the like Is preferably carried out by Specifically, after the discharge port 13 is arranged at a position as shown in FIG. 11, it is performed by sandwiching and heat-sealing it from both sides of one sheet and the other sheet surface of the container body 2. Is preferred.

The first stress applying portion and the second stress applying portion in the discharge port 13 are not limited to those having the above-described configuration, and can be joined to one sheet inner surface and the other sheet inner surface constituting the soft bag.

For example, it may not be formed so as to extend in the axial direction of the medicine container, but may be formed obliquely with respect to the medicine container.
In the medical container 10 of this embodiment, when the drug chamber 11 is inflated by pressing the drug chamber 11 of the medical container 10, this expansion (opening of the first fixing portion and the second fixing portion) is interlocked. Then, as shown in FIGS. 16 and 17, the first stress applying portion 21 and the second stress applying portion 22 open in the direction of one sheet 2a and the other sheet 2b. The tip side portion is broken, and then the first stress applying portion side portion and the second stress applying portion side portion are broken.

It is preferable to include a detachable spread suppressing inter-sheet fixing portion 85 for suppressing the spread between the sheets fixed by the second stress applying portion 22 and the second stress applying portion 22.
In the embodiment shown in FIG. 18, the spread suppressing sheet fixing portion 85 is formed in an arc shape in the vicinity of the distal ends of the first stress applying portion 21 and the second stress applying portion 22 of the discharge port 13. It is preferable that the inter-sheet fixing portion for suppressing the spread is not peeled off by pressure applied to the container main body 2 before use such as during transportation, but can be peeled off when the container main body 2 is strongly pressed with fingers. The sheet-to-sheet fixing portion 85 is preferably an arc-shaped one that is continuous with a position near the tip of the stress applying portions 21 and 22 and inside the drug chamber as in the illustrated embodiment. The inter-sheet fixing portions 85 may not be continuous but may be scattered. Further, the inter-sheet fixing portion 85 may be provided in such a manner that one or two stress applying portions 21 and 22 are sandwiched between the tip portions of the stress applying portions 21 and 22 and on the side surfaces thereof. Further, as shown in FIG. 18, it is preferable that the spread suppressing sheet fixing portion 85 does not form a chamber partitioned from the drug chamber 11.

  The inter-sheet fixing portion 85 is preferably formed by fusing the container body 2 so as to be peelable. The fusion is preferably thermal fusion, high frequency fusion or the like. The inter-sheet fixing portion 85 is preferably performed by a hot press, and the mold temperature can be formed by performing the process at a temperature lower by 10 ° C. or more than the melting temperature of the forming material of the container body 2. By having the inter-sheet fixing portion for suppressing spread, there is no possibility that the container main body 2 swells during transportation and the first stress applying portion 21 and the second stress applying portion 22 are cleaved.

Next, a medical container 30 according to another embodiment of the present invention will be described.
FIG. 19 is a front view of another embodiment of the medical container of the present invention. FIG. 20 is a cross-sectional view of an example of a medicine discharge port used for the medical container of the present invention. FIG. 21 is a cross-sectional view of another example of the medicine discharge port used in the medical container of the present invention.
The medical container 30 of this embodiment is in communication with two drug storage units 11 and 12 divided by a releasable partition unit 9, drugs stored in the respective drug storage units, and any drug storage unit. The medical container 30 includes a discharge port 33 into which the medicine discharge needle tube can be inserted, and the medical container 30 is inserted into the discharge port 33 when the partition part 9 is not released. A needle tube intrusion inhibiting unit 4 that inhibits entry is provided.
The medical container 30 of this embodiment includes a container main body 52 formed of a sheet-like cylindrical body, and the container main body 52 partitions an internal storage portion and forms a partition portion 9 that can be released. The storage section is divided into a first drug chamber 11 that is a first drug storage section and a second drug chamber 12 that is a second drug storage section. The medical container 30 also has a medicine discharge port 3 a attached to the first medicine chamber 11 of the container body 52. The first medicine chamber 11 contains the first medicine, and the second medicine chamber 12 contains the second medicine.

In particular, in the medical container 30 of this embodiment, the first drug chamber 11 is filled with a chemical solution, and due to the presence of the filled chemical solution, the operation portion 31b of the flow restricting portion before the weak seal portion 9a is peeled off. It is preferable that the breaking operation by is difficult.
And since the medical container 30 is provided with the needle tube penetration inhibiting part 4 as described above, the separation work of the partition part of the container body, that is, the communication work between the first medicine chamber and the second medicine chamber is performed. Therefore, it is possible to prevent the drug solution from being administered. In particular, if the breaking operation by the operation portion 31b of the flow restricting portion before the weak seal portion 9a is peeled is difficult, the communication work between the first drug chamber and the second drug chamber is more reliably performed. It is possible to prevent the drug solution from being administered.
The medical container 30 includes a container main body 52, a discharge port 3a, and a mixed injection port 7. The mixed injection port 7 may not be provided.
If it demonstrates concretely, as shown in FIG. 1, the seal | sticker parts 5 and 6 are provided in the one end side and other end side of the container main body 52. As shown in FIG. In addition, the medical container 30 of this embodiment includes a medicine discharge port 3 a provided in the first medicine chamber 11 and a mixed injection port 7 provided in the second medicine chamber 12. And the 1st chemical | medical agent chamber is in the state swelled to some extent with the filled 1st chemical | medical solution, and it is difficult to fracture | rupture the operation part 31b of the distribution control part of the discharge port 3a over a container. It has become. It should be noted that the breaking operation may be difficult to some extent and may not be impossible at all.

As the container main body 52 of the medical container 1, what was demonstrated in the container main body 2 mentioned above can be used conveniently.
And the container main body 52 is provided with the partition part 9, and the inside is divided into 2 chambers by this. The partition portion 9 includes a peelable weak seal portion 9a that traverses the container body 52 in the entire horizontal direction, and a substantially non-peelable strong seal portion 9b provided in a branch portion at both ends of the weak seal portion 9a. Yes.
And it is preferable to perform a weak seal | sticker part by a hot press, and it can form by performing the temperature of a metal mold | die at a temperature lower by 10 degreeC or more than the melting temperature of the formation material of the container main body 52. FIG.

In addition, the volume of the medical container 30 varies depending on the type of medicine stored therein, but it is usually preferable that the volume of the first medicine chamber is about 50 to 5000 ml. The volume is preferably about 50 to 5000 ml.
By dividing the drug chamber into two in this way, it can be stored separately until it uses a liquid containing a substance that causes alteration or deterioration due to reaction, etc., and it is preferable to mix both liquids in use. Can be applied to. As a medicine stored in each medicine room, a medicine, a powder, etc. can be considered. In particular, in the medical container of the present invention, the first drug is preferably a chemical solution. The second drug may be either a chemical solution or a powder. A chemical solution is preferable. Examples of the combination of the first drug and the second drug include combinations of an amino acid electrolyte solution and a glucose solution, a glucose solution and a sodium bicarbonate solution, and the like.
The medicine discharge port 3a is for discharging the medicine (chemical solution) filled in the container body 52. As shown in FIG. 20, the discharge port 3a in this embodiment is the same as the discharge port 3 shown in FIGS. 2 to 4 and described above, except that no medicine is stored. As shown in FIGS. 20, 2, 3, and 4, the discharge port 3 a is fixed to the drug chamber 11 and includes a port main body portion 31 including a breakable flow restricting portion, and the port main body portion 31. A discharge port 33 having a sealing portion 32 that can be connected to a drug discharge needle tube that closes the end side, and a needle tube intrusion inhibition portion 4 provided in the port main body portion 31 are provided.

Also in the discharge port 3 a, the needle tube intrusion inhibiting portion 4 is housed in the same manner as the discharge port 3. As shown in FIG. 20, the needle tube intrusion inhibiting unit 4 in this embodiment includes a distal end portion 41 capable of abutting against the operation portion 31 b (lower surface of the bottom of the operation portion) and a base capable of abutting the distal end of the drug discharge needle tube. It has an end portion 42 and a connecting portion 43 that connects the distal end portion 41 and the proximal end portion 42.
When the breakable portion of the flow restricting portion is in an unbroken state (the state shown in FIG. 20), when the medicine discharge needle tube is punctured into the sealing portion 32, the distal end of the needle is the proximal end portion of the needle tube entry inhibiting portion 4. Even if the needle tube intrusion inhibiting portion 4 is in contact with 42 and further pressed, the needle tube entry inhibiting portion 4 moves upward, and after the distal end portion 41 abuts on the operation portion 31b, it cannot be moved any more. Further, the needle tube intrusion inhibiting portion 4 of this example is slightly movable in the cylindrical portion, but in the state where the proximal end portion 42 is in contact with the sealing portion 32, the distal end portion 41 and the operation portion 31b. There may be almost no distance between (the bottom surface of the bottom of the operation unit) and it cannot be moved substantially.
Then, the operator recognizes that the flow restricting portion is not broken, that is, that the partition portion is not peeled off, because the medicine discharge needle tube is not puncturable.

The punctureable length of the discharge port of the drug discharge needle tube when the breakable portion of the flow restricting portion is not broken (the state shown in FIG. 20) is such that the opening of the drug discharge needle tube does not communicate with the inside of the discharge port. It is preferable. Therefore, it is preferable that the movable distance in the discharge port of the needle tube entry inhibiting portion 4 is 5 mm or less.
Further, the needle tube intrusion inhibiting unit 4 is not limited to the above-mentioned type. For example, the needle tube intrusion inhibiting unit 4d shown in FIG. The obstruction part 4a is of a cylindrical type with the lower end closed, or a hollow columnar type (not shown, in other words, a cylindrical type with the upper end and lower end closed). May be. In these cases, the distal end portion 41 formed by the upper end contacts the operation portion 31b, the proximal end portion 42 formed by the bottom surface contacts the distal end of the drug discharge needle tube, and the side surface portion connects the distal end portion 41 and the proximal end portion. A connecting portion 43 to be connected is configured. The cross-sectional shape in the columnar and cylindrical types as described above may be any of a circle (columnar, cylindrical) including an ellipse, a polygon (for example, a triangle, a quadrangle), and the like.

And the needle tube penetration | inhibition part 4 of the example mentioned above can flow out from a discharge port after the fracture | rupture of the breakable part of a distribution control part. However, it is not limited to such a thing.
For example, as in the discharge port 36 of the example shown in FIG. 6, the needle tube entry inhibiting portion does not flow out from the port main body portion 31 as long as it does not inhibit the puncture of the drug discharge needle tube after the breakable portion is broken. It may be. In the discharge port 36, the inner diameter of the port main body 31 near the breakable portion is smaller than the outer diameter of the proximal end portion 42 of the needle tube entry inhibiting portion 4c. For this reason, even after the breakable portion of the flow restricting portion breaks, even if the needle tube penetration inhibiting portion 4c rises due to buoyancy, the needle tube penetration inhibiting portion is formed on the upper portion (the portion that was the breakable portion) of the broken tubular portion 31a. The base end part 42 of 4c contacts and is locked, and does not flow out from the cylindrical part.

In the case of such a type, it is preferable that the needle tube entry inhibiting portion 4b has an opening at the base end portion 42 as shown in FIG. In the needle tube entry inhibiting portion 4b, the opening is configured by a plurality of slits 44a extending inward from the periphery of the base end portion. Note that the opening may be a through-hole provided in the base end portion 42 as in the needle tube entry inhibition portion 4c shown in FIG. In this example, a plurality of (for example, 2 to 8, specifically, four) through holes 45a are provided.
Furthermore, although the needle tube penetration | inhibition inhibiting part 4 of the example mentioned above is a thing isolate | separated from the operation part 31b, it is not limited to such a thing. For example, like the discharge port 53 shown in FIG. 9, the distal end portion 64a of the needle tube entry inhibiting portion 64 may be fixed to the operation portion 31b. And in this discharge port 53, after the breakable portion of the flow restricting portion breaks, the needle tube entry inhibiting portion 64 rises together with the operation portion 31b and flows out from the tubular portion. In the case where such a needle tube intrusion inhibiting portion is integrated with the operation portion, the needle tube intrusion inhibiting portion needs to be in a form that does not hinder the breaking operation in the operation portion.

Also, in this type of discharge port, for example, as long as the discharge port 63 shown in FIG. May not flow out of the port body 31. In the discharge port 63, the inner diameter of the port main body 31 in the vicinity of the breakable portion is smaller than the outer diameter of the proximal end portion 64 b of the needle tube entry inhibiting portion 64. For this reason, even after the breakable portion of the flow restricting portion breaks, even if the needle tube intrusion inhibiting portion 64 rises due to buoyancy together with the operation portion 31b, the upper portion of the broken tubular portion 31a (the portion that was the breakable portion) The proximal end portion 64b of the needle tube entry inhibiting portion 64 comes into contact with and is locked and does not flow out of the cylindrical portion.
In the case of such a type, it is preferable to have an opening at the base end portion 64b in order to ensure the flow of the chemical solution. As the opening, those shown in FIGS. 7 and 8 and described above are preferable.

Hard or semi-rigid resin is suitable as a material for forming the cylindrical portion, the needle tube intrusion inhibiting portion, and the cap portion in all the embodiments described above. As a material for forming the cylindrical portion, a material that can be fused to the container body by ultrasonic fusion, heat sealing, or the like is preferable. Moreover, as a forming material of the cap part 33a, hard or semi-rigid resin is suitable. Further, the material for forming the cap portion 33a is preferably a material that can be fused to the port body portion 31 by ultrasonic fusion, high frequency fusion, or the like. In addition, as shown in FIG. 3, the port main body portion 31 preferably includes a flange portion 31 d having an annular recess that accommodates the tip portion of the cap portion at the rear end. The cap portion 33a includes a flange portion 33b that comes into contact with the flange portion 31d, and a tip portion 33c that is accommodated in the annular recess of the cylindrical portion. And the port main-body part 31 and the cap part 33a are fixed liquid-tightly in the contact surface of both flange parts.
As the forming material of the cylindrical portion, the needle tube entry inhibition portion, the cap portion, and the sealing portion (elastic member) 32, those described above can be suitably used.

  The medicine may be stored in the discharge port 3a of the medical container 30 of this embodiment.

In these cases, the distal end portion 41 formed by the upper end can contact the weak seal portion for preventing communication, the proximal end portion 42 formed by the bottom surface contacts the distal end of the drug discharge needle tube, and the side surface portion is the distal end portion 41. And a connecting portion 43 that connects the base end portion 42 to each other. The cross-sectional shape in the columnar and cylindrical types as described above may be any of a circle (columnar, cylindrical) including an ellipse, a polygon (for example, a triangle, a quadrangle), and the like.

  And the needle tube penetration | inhibition part 4 of this example can flow out from a discharge port after peeling of a weak seal part. However, it is not limited to such a thing. For example, like the discharge port 83a in the example shown in FIG. 28, the needle tube entry inhibiting part 4 may not flow out from the cylindrical part 61. In this discharge port 83 a, the inner diameter in the vicinity of the distal end portion of the cylindrical portion 61 is smaller than the outer diameter of the proximal end portion 42 of the needle tube entry inhibiting portion 4. For this reason, even after the breakable portion of the flow restricting portion is broken, even if the needle tube entry inhibiting portion 4 is lifted by buoyancy, the base end portion 42 of the needle tube entry inhibiting portion 4 comes into contact with the upper portion of the tubular portion 61 and is locked. And does not flow out of the cylindrical portion. In the case of such a type, it is preferable to have an opening at the base end portion 42 as in the needle tube entry inhibiting portion 4b shown in FIG. 7 in order to ensure the circulation of the chemical solution. In the needle tube entry inhibiting portion 4b, the opening is configured by a plurality of slits 44a extending inward from the periphery of the base end portion. Note that the opening may be a through-hole provided in the proximal end portion 42 as in the needle tube entry inhibiting portion 4c shown in FIG. In this example, a plurality of (for example, 2 to 8, specifically, four) through holes 45a are provided.

  Further, the medicine 8 may be stored in the third chamber 25 as in the medical container 90 shown in FIG. The medicine to be stored may be any powder, granule or other solid form or liquid form. Drugs are formulated and dissolved in infusions. For example, antibiotics, vitamins (general vitamins), various amino acids, antithrombotics such as heparin, insulin, antitumor agents, analgesics, cardiotonics, statics Note: Anesthetic agents, anti-Parkinson agents, ulcer treatment agents, corticosteroid agents, arrhythmia agents, correction electrolytes, antiviral agents, immunostimulants, and the like.

Next, a medical container 100 according to another embodiment of the present invention will be described.
FIG. 32 is a front view of another embodiment of the medical container of the present invention. FIG. 33 is a front view of another embodiment of the medical container of the present invention.
The medical container 100 according to this embodiment includes two drug storage units 11 and 12 divided by a releasable partition unit, a drug stored in each drug storage unit, and any one of the drug storage units 11 and 12. The medical container 100 is provided with a discharge port 33 through which the medicine discharge needle tube can be inserted, and the medical container 100 has a medicine discharge needle tube connected to the discharge port 33 when the partition portion is not released. A needle tube intrusion inhibiting unit 4 that inhibits insertion is provided.

The medical container 100 of this embodiment is formed of a flexible material and is divided into a first drug chamber 11 and a second drug chamber 12 by a partition portion 9 having a peelable weak seal portion 9a. 102, the medicine discharge port 3 attached to the first medicine chamber 11 of the container body 102, and the detachable operation part movement suppression provided at a position close to or in contact with the distal end of the operation part 31b of the discharge port 3 Weak seal portion 26, the first medicine filled in first medicine chamber 11, the second medicine housed in second medicine chamber 12, and the third medicine housed in the discharge port It is a medical container containing medicine.
The operation portion movement restraining weak seal portion 26 is provided at a position close to or in contact with the distal end portion of the operation portion 31b of the discharge port 3 and is detachable and suppresses movement of the operation portion 31b after rupture before peeling. Is.
The medicine discharge port 3 is for discharging the medicine (chemical solution) filled in the container main body 102. The discharge port 3 shown in FIGS. 3 and 4 is preferably the same as described above. Further, an appropriate amount of medicine 8 is accommodated in the discharge port 3. Moreover, it is preferable that the formation part of this medicine storage part 34 of this discharge port 3 is formed transparent so that an internal medicine can be visually observed. The medicine to be stored may be any powder, granule or other solid form, or liquid form.

Drugs are formulated and dissolved in infusions. For example, antibiotics, vitamins (general vitamins), various amino acids, antithrombotic agents such as heparin, insulin, antitumor agents, analgesics, cardiotonics, statics Note: Anesthetic agents, antiparkinsonian agents, ulcer treatment agents, corticosteroid agents, arrhythmia agents, correction electrolytes, antiviral agents, immunostimulants, and the like. Moreover, although the cylindrical part 31a of the discharge port 3 may be a normal pressure, it is good also as a pressure reduction or a vacuum state. As described above, when the medicine container is in a reduced pressure or vacuum state, the effect of preventing the degradation / degradation and the like of the medicine is improved, and when the breakable portion 31c is broken, the infusate is sucked to form a cylinder more quickly. It can introduce into the part 31a.
As shown in FIGS. 2, 3, and 4, the discharge port 3 is fixed to the drug chamber 11 and includes a port main body portion 31 including a flow restricting portion that can be broken, and the other end side of the port main body portion 31. A discharge port 33 having a sealing portion 32 capable of connecting a closed medicine discharge needle tube and a needle tube intrusion inhibiting portion 4 provided in the port main body portion 31 are provided.

The port main body 31 closes the cylindrical portion 31a and one end side of the cylindrical portion 31a, and enables communication between the first drug chamber 11 of the container main body 102 and the inside of the cylindrical portion 31a by breaking. A flow restricting portion including a breakable portion 31c and an operation portion 31b for performing a breaking operation of the breakable portion 31c is provided.
The breakable portion 31c is a portion where a wedge-shaped annular recess is formed, and is thinner than other portions. For this reason, the breakable portion 31c is weaker than other portions, and by pushing the operation portion 31b from the outside of the bag, the breakable portion 31c is broken at the breakable portion 31c. Separated from the part 31a. And it is preferable that the operation part 31b to isolate | separate is hollow so that it may show in figure. By doing in this way, the breakable part 31c becomes a state without uneven thickness. The distance between the inner upper surface of the tubular portion 31a and the breakable portion 31c is preferably 1 to 2 mm.

Furthermore, you may form this operation part 31b in the color discriminable with respect to the chemical | medical solution after mixing a chemical | medical agent. It can be easily identified from the chemical solution, and the remaining amount of the chemical solution can be easily confirmed because it floats on the chemical surface. The color distinguishable with respect to the drug solution after mixing the drug differs depending on the drug solution and the drug used, and is not unique. For example, if the color of the drug solution after mixing the drug is yellow, If white (red, blue, green, black) is red, it is not red (for example, white, yellow, blue, green, black). In addition, when the color of the chemical | medical solution after a chemical | medical agent mixing is colorless, as long as it is colored, what kind of color may be sufficient.
The sealing portion 32 is formed of an elastic member that seals the rear end opening of the cylindrical portion and can be pierced by the needle tube for discharging the medicine. It is fixed at the rear end.

Also in the medical container 100 of this embodiment, the needle tube entry inhibiting portion 4 is accommodated in the discharge port 3. As shown in FIG. 3, the needle tube intrusion inhibiting unit 4 in this embodiment includes a distal end portion 41 that can abut on the operation portion 31 b (the bottom surface of the bottom of the operation portion) and a base on which the distal end of the drug discharge needle tube can abut. It has an end portion 42 and a connecting portion 43 that connects the distal end portion 41 and the proximal end portion 42.
In the state where the breakable portion of the flow restricting portion is not broken (the state shown in FIG. 3), when the medicine discharge needle tube is punctured into the sealing portion 32, the distal end of the needle is the proximal end portion of the needle tube entry inhibiting portion 4 Even if the needle tube intrusion inhibiting part 4 is moved upward and the tip part 41 is brought into contact with the operation part 31b, it cannot move any further even if it is brought into contact with 42 and further pressed. Further, the needle tube intrusion inhibiting portion 4 of this example is slightly movable in the cylindrical portion, but in the state where the proximal end portion 42 is in contact with the sealing portion 32, the distal end portion 41 and the operation portion 31b. There may be almost no distance between (the bottom surface of the bottom of the operation unit) and it cannot be moved substantially.

In the needle tube entry inhibiting portion 4 of this example, the tip portion 41 is hemispherical. By doing in this way, it becomes the shape which is hard to be caught in the inner edge part after the fracture | rupture of a breakable part. Further, the needle tube entry inhibiting portion 4 includes a wing portion 46 that is provided on the side surface of the connection portion 43, extends to the proximal end side from an appropriate position of the connection portion 43, and has a lower end continuous with the peripheral edge of the proximal end portion 42. . By providing such a wing portion, the base end portion 42 is prevented from being caught by the inner edge portion after the breakable portion of the breakable portion. In this example, the wing part 46 extends from the tip part 41.
Further, the needle tube intrusion inhibiting portion 4 is not limited to the above-mentioned type. For example, the needle tube intrusion inhibiting portion 4 shown in FIG. It may be.

And the needle tube penetration | inhibition part 4 of the example mentioned above can flow out from a discharge port after the fracture | rupture of the breakable part of a distribution control part. However, it is not limited to such a thing.
For example, as shown in FIG. 6 and the discharge port 36 described above, the needle tube entry inhibiting portion does not flow out from the port main body portion 31 as long as it does not inhibit the puncture of the drug discharge needle tube after the breakable portion is broken. It may be a thing. In the case of such a type, it is preferable to have an opening at the base end portion 42 as in the needle tube entry inhibiting portion 4b shown in FIG. 7 in order to ensure the flow of the chemical solution. In the needle tube entry inhibiting portion 4b, the opening is configured by a plurality of slits 44a extending inward from the periphery of the base end portion. Note that the opening may be a through-hole provided in the base end portion 42 as in the needle tube entry inhibition portion 4c shown in FIG. In this example, a plurality of (for example, 2 to 8, specifically, four) through holes 45a are provided.
Also in this type of needle tube entry inhibiting portion 4b, the tip portion 41 is preferably hemispherical. Moreover, although a wing | blade part may be provided, it is preferable not to provide.

Furthermore, although the needle tube penetration | inhibition inhibiting part 4 of the example mentioned above is a thing isolate | separated from the operation part 31b, it is not limited to such a thing. For example, like the discharge port 53 shown in FIG. 9 and described above, the distal end portion 64a of the needle tube entry inhibiting portion 64 may be fixed to the operation portion 31b. Also in the needle tube penetration inhibiting part 64 of this example, similarly to the needle tube penetration inhibiting part 4 described above, it is provided on the side surface of the connection part 43, extends from the appropriate position of the connection part 43 to the proximal side, and the lower end is the proximal part. It is preferable to provide a wing portion that is continuous with the peripheral edge of 42.
Further, even in this type of discharge port, for example, as long as the discharge port 63 shown in FIG. 10 and described above does not hinder the puncture of the drug discharge needle tube after the breakable portion is broken, the needle tube enters. The inhibiting part may not flow out from the port body part 31. In the discharge port 73, the inner diameter of the port main body 31 in the vicinity of the breakable portion is smaller than the outer diameter of the proximal end portion 64 b of the needle tube entry inhibiting portion 64. For this reason, even after the breakable portion of the flow restricting portion breaks, even if the needle tube intrusion inhibiting portion 64 rises due to buoyancy together with the operation portion 31b, the upper portion of the broken tubular portion 31a (the portion that was the breakable portion) The proximal end portion 64b of the needle tube entry inhibiting portion 64 comes into contact with and is locked and does not flow out of the cylindrical portion.
In the case of such a type, it is preferable to have an opening at the base end portion 64b in order to ensure the flow of the chemical solution. As the opening, those shown in FIGS. 7 and 8 and described above are preferable.

The medical container 100 of this embodiment includes a container main body 102 formed of a sheet-like cylindrical body, and the container main body is formed with a partition portion 9 that partitions an internal storage portion.

In addition, as the container main body 102, the same thing as the container main body 52 mentioned above except the weak seal part 26 for operation part movement suppression is used.
In this embodiment, the weak seal portion 26 for suppressing movement of the operating portion is formed so as to surround the upper portion of the discharge port 3, similarly to the weak seal portion 24 for inhibiting communication. A third chamber 25 that is isolated from the first drug chamber 11 is formed by the weak seal portion 26 for suppressing movement of the operation portion. The third chamber 25 is an empty room. However, a predetermined liquid (for example, physiological saline) may be placed in the third chamber. The third chamber may be in a dry state, but may be filled with a small amount of liquid for sterilization. Further, a passage through which some water vapor or medicine passes through the weak seal part 26 for suppressing movement of the operation part may be formed and communicated with the first medicine chamber 11 at the above level. The operation portion movement restraining weak seal portion 26 can be formed by heat-sealing the sheet material in a band shape (thermal fusion, high-frequency fusion, ultrasonic fusion, etc.).

In the embodiment shown in FIG. 32, the weak seal portion 26 for suppressing operation portion movement is formed in an inverted U-shape. In addition, the weak seal part for communication inhibition has a trapezoidal shape with the short side on the upper side, a triangular shape with the discharge port at the top, a triangular shape with the discharge port at the bottom, a polygonal shape such as a quadrangle, a substantially semicircular shape, a substantially It may be semi-elliptical.
Further, it is preferable that the seal strength of the weak seal portion 26 for suppressing the operation portion movement is equal to, slightly larger or slightly smaller than the seal strength of the partition weak seal portion 9a. If it is such, a chemical | medical solution will not be administered in the state in which the weak seal part 9a for a partition is not peeled, and administration preparation can be performed by easy operation.

The weak seal portion 26 for suppressing movement of the operating portion is pressed against the first drug chamber 11 so that the weak seal portion 26 for suppressing movement of the operating portion is peeled off almost simultaneously with or subsequently to the peeling of the weak seal portion 9a for partitioning. It is preferable that By doing in this way, when the 1st chemical | medical agent chamber 11 of the container main body 102 is compressed, the operation part movement suppression weak seal part 26 does not peel ahead of the partition weak seal part 9a.
Moreover, the medical container 100 may be one in which the weak seal portion 26 for suppressing movement of the operation unit is peeled off after the weak seal portion 9a for partitioning is peeled by pressing the second drug chamber 12. If this is the case, the second drug chamber 12 of the container main body 102 is pressed, and the weak seal portion 26 for suppressing movement of the operating portion is peeled off by the force of the fluid when the weak seal portion 9a for partitioning is peeled off. Can do.

  The medicine discharge port 3 is for discharging the medicine (chemical solution) filled in the container main body 102. 25 and 27, the discharge port 3 in this embodiment is fixed to the medicine chamber 11 and has a cylindrical portion 61 having an open end and the other end side of the cylindrical portion 61.

And the cylindrical part 61 and the cap part 33a are fixed liquid-tightly in the contact surface of both flange parts.

In this medical container 100, the distal end portion of the operation portion 31 b of the discharge port 3 is in proximity to or in contact with the weak seal portion 26 for suppressing operation portion movement. Therefore, even if the operation portion 31b is broken before the weak seal portion 9a for partitioning and the weak seal portion 26 for suppressing movement of the operation portion are peeled, the operation portion 31b Movement is restricted by the movement restraining weak seal portion 26, and the needle tube intrusion inhibiting portion 4 in the discharge port 3 can not substantially move, so that the medicine discharge needle tube cannot be connected. As a normal operation in the medical container 100, by pressing the first drug chamber 11 or the second drug chamber 12, the partition weak seal portion 9a is peeled and the operation portion movement restraining weak seal portion 26 is peeled. After the first medicine and the second medicine are mixed, the medicine in the discharge port is mixed with the medicine in the container body by operating the operation part of the discharge port 3 and breaking.
