Description

  TECHNICAL FIELD The present invention relates to an infusion container and a method for producing an infusion container in which a drug can be prepared and blended in a drug solution such as an infusion solution.

Prior to infusion to the patient, mix and dissolve drugs such as vitamins and antibiotics that are difficult to pre-mix into the infusion in a vial or soft soft bag containing the infusion. It is done to adjust the chemicals.
In the case of a liquid drug, such adjustment of the drug solution is carried out as it is, and in the case of a solid drug, the solution is added and dissolved by a syringe, and then sucked into a syringe and filled in an infusion solution or a soft bag. It is done by injection mixing.
However, such adjustment of the chemical solution has a disadvantage that the operation procedure is complicated, and is particularly inconvenient when a rapid infusion is required. In addition, the adjustment of the chemical solution as described above may cause contact with contaminated atmosphere or equipment because part of the infusion is taken out and mixed and dissolved in another container. There was a risk of contamination.

In order to solve such problems, the container and the solution (infusion solution) can be mixed aseptically and separated into two by heat-sealing the inner space of the container consisting of a soft bag with a sealing part. And the container which accommodates a chemical | medical agent and a solution in each space is disclosed (patent document 1). When it is necessary to prepare a chemical solution, the outside of the container is pressed to break the seal portion, and the drug and the solution are mixed.
Since the entire container is composed of a flexible sheet material, when a pressure is applied from the outside of the container, a hard solid drug and the sheet material may rub against each other to generate a pinhole. When pinholes are generated in this way, gas, for example, moisture in the air, oxygen, carbon dioxide, or the like may enter from the pinholes and alter the chemicals in the container.
Alternatively, the seal part can be easily broken by external pressure or impact, and the dissolved solution leaks and mixes the drug with the dissolved solution except when necessary, so that the stability and safety of the drug can be maintained. It can be difficult.
Furthermore, since a flexible sheet material generally has a relatively high gas permeability, there is a case where the chemical comes into contact with moisture, oxygen, etc. due to gas intrusion into the container and decomposes or deteriorates. Therefore, a portion of the container in which the medicine is accommodated is double-wrapped with a gas-impermeable packaging material, and an oxygen scavenger and a desiccant are enclosed inside the packaging material.

However, packaging with a packaging material or encapsulating an oxygen scavenger or the like in this way makes the manufacturing process complicated and makes the container bulky, which is disadvantageous for transportation and storage.
In order to solve such problems, a breakable communication restricting member is arranged between two containers, and when it is necessary to mix the medicine inside, the communication restricting member is pushed from the outside of the container with a finger. In addition, a type has been devised in which the membrane of the communication regulating member is destroyed, two chambers are communicated, and a drug is mixed (Patent Document 2).
However, in this type of infusion container, the medicine in the medicine container 5 may be administered from the infusion outlet (discharge port) 7 before the two containers are communicated. In this case, only the medicine in the medicine container 4 may be administered at a high concentration and the proper use of the medicine may not be performed.

The drug container 3 includes a drug storage unit 4 in which a drug is stored, a discharge port 5 that is provided independently of the drug storage unit 4 and discharges the contents inside the soft bag, the drug storage unit 4 and the discharge. Provided at one end of the port 5 and disposed inside the soft bag, restricts the communication between the medicine container 4 and the discharge port 5 and the inside of the soft bag, and connects both the medicine container 4 and the discharge port 5 to the inside of the soft bag. It has the communication control part 6 which can be communicated with.

  In other words, the infusion container 1 of the present invention includes a soft bag 2 in which a chemical solution is stored and a medical member 3 attached to the soft bag 2, and the medical member 3 stores a drug. The medicine storage part 4, the discharge port part 5 for discharging the contents inside the soft bag 2, the one end part of the medicine storage part 4 and the discharge port part 5 and disposed inside the soft bag 2, A communication restriction mechanism 6 is provided that restricts communication between the medicine container 4 and the discharge port 5 and the inside of the soft bag 2 and enables the medicine container 4 and the discharge port 5 to communicate with the inside of the soft bag 2. . That is, in the infusion container 1, the medical member is configured by the drug container 3, and the communication restriction mechanism is configured by the communication restriction unit 6.

The infusion container 1 of the present invention comprises a soft bag 2 and a drug container 3 attached to one end of the soft bag 2 as shown in FIGS. In this embodiment, communication between the medicine container 4 and the inside of the soft bag and communication between the discharge port 5 and the inside of the soft bag are possible by a single operation of the communication restricting portion 6. By operating the communication restricting portion 6, both the medicine storage portion 4 and the discharge port 5 can be communicated with the inside of the soft bag almost simultaneously.
The soft bag 2 is an infusion container having a medicine storage space inside. At one end and the other end of the soft bag 2 are provided seal portions 43a and 43b in which a soft resin sheet is fused to a predetermined width. In the embodiment shown in FIG. 1, the medicine storage space of the soft bag 2 is divided into a plurality of medicine chambers by a partition 40. In the embodiment shown in FIG. 1, the chemical solution storage space is divided into a first drug chamber 41 and a second drug chamber 42 by a partition 40.

  The partition part 40 is formed by the weak seal part which can be peeled. The weak seal portion is peeled off when strongly pressed with a finger, and the first drug chamber 41 and the second drug chamber 42 communicate with each other. The peel strength of the weak seal portion is preferably such that it does not peel off by the pressure applied to the soft bag 2 during transportation but peels when the soft bag is strongly pressed with fingers. The weak seal portion is preferably formed by fusing the weak seal forming portion of the soft resin sheet. As the fusion, a heat seal, a high frequency seal or the like is preferable. Since the soft bag 2 has a plurality of drug chambers divided by weak seal portions, a plurality of drugs can be mixed aseptically in the soft bag. The soft bag 2 is not limited to the one having the multi-chamber structure as described above, and may have a single-chamber structure.

  The soft bag 2 is made of a soft synthetic resin having a certain degree of heat resistance, such as polyolefin (for example, a mixture containing polyolefin such as polyethylene, polypropylene, ethylene-propylene copolymer, a mixture of polypropylene and polyethylene or polybutene), and further parts thereof. Cross-linked product, ethylene-vinyl acetate copolymer (EVA), polyester (polyethylene terephthalate, polybutylene terephthalate), soft vinyl chloride resin, polyvinyl acetate, polyvinylidene chloride, silicone, polyurethane, polyamide elastomer, polyester elastomer, styrene / ethylene・ Various thermoplastic elastomers such as styrene elastomers such as butylene / styrene copolymer or any combination of these (blend resin, poly -Alloy, laminated body, etc.), a resin layer of a hard material such as a polyester such as polyethylene terephthalate and polyethylene naphthalate, a polyamide such as nylon, and the above-mentioned soft material (for example, polyethylene) A multilayer structure sheet made of a resin layer is used. By molding with these soft resins, the operation of the communication restricting portion 6 described later can be easily performed from the outside of the soft bag 2.

Preferred soft resin materials include a mixture of a plurality of polyethylenes having different densities, a multilayered sheet, or a polypropylene resin composition softened by blending a styrene elastomer or an olefin elastomer. These have heat resistance that can withstand the high temperatures of autoclave sterilization, and are excellent in handleability because they are rich in flexibility and transparency. Furthermore, there is an advantage that it is easy to be fixed by molding and processing to the soft bag 2 and fusion of the drug container 3 and the manufacturing cost can be reduced. The thickness of the sheet material constituting the flexible bag 2 is not particularly limited and varies depending on the material constituting the sheet. For example, in the case of the above-described polypropylene resin composition, the thickness is preferably about 20 to 500 μm. As the soft bag 2, it is desirable to use an extruded film or a blown tube having a tensile elastic modulus of 500 MPa or less, preferably 50 to 300 MPa.
The soft bag 2 is produced by blow molding using any one of the above resins, the one formed by welding the peripheral portions of two sheets formed from the resin, and the one formed by the resin. Any one of a sheet formed by folding a sheet and welding the peripheral edge part, or a sheet formed by extrusion molding using the above resin and welded to the peripheral edge of the opening may be used.

  An infusion solution (chemical solution) is accommodated in the medicine storage space. Examples of the infusion include physiological saline, electrolyte solution, Ringer's solution, high calorie infusion, glucose solution, water for injection, amino acid electrolyte solution, and the like, but are not limited thereto. For example, a glucose electrolyte solution is stored in one of the first drug chamber 41 and the second drug chamber 42, an amino acid solution is stored in the other chamber, and vitamin B1, vitamin B2, vitamin B6, vitamin C, panthenol, nicotine are stored in both chambers. Water-soluble vitamins such as acid amides can be appropriately sorted and stored in consideration of stability and the like. In this case, a vitamin-containing high-calorie total infusion solution can be obtained by storing a liquid preparation mainly composed of fat-soluble vitamins such as vitamin A, vitamin D, vitamin E, and vitamin K in the medicine storage section 4 described later.

  In addition, the seal portion 43b on the other end side of the soft bag 2 is provided with a hole (hanging portion) 45 for hanging on a hanger or the like. Furthermore, in order to maintain the quality of the chemical solution, a film such as an aluminum foil may be laminated on the soft bag 2 in order to impart oxygen barrier properties, light shielding properties, and the like. Further, a thin film such as a vapor deposition film made of an oxide such as titanium oxide, aluminum oxide, or silicon oxide may be formed on the surface of the soft bag 2 in order to impart oxygen barrier properties. Or you may provide the resin film which has these thin films as an intermediate | middle layer.

As shown in FIG. 1, the drug container 3 is attached so that the communication restricting portion 6 is in the drug solution storage space of the soft bag 2.
As shown in FIGS. 2 and 5, the medicine container 3 includes a main body portion 7, a lid portion 8, and a communication restriction portion 6.
The main body 7 has a tapered diameter toward the communication restricting portion. As shown in FIG. 6, the cross section of the main body 7 has a rectangular shape with both sides chamfered. The main body 7 may have a circular, elliptical, polygonal cross section, or the like. And inside the main body 7, a medicine container 4 and a discharge port 5 are formed. As shown in FIGS. 5 and 6, the medicine storage unit 4 and the discharge port 5 are preferably arranged in parallel. Moreover, as shown in FIG. 6, it is preferable that the medicine storage part 4 and the discharge port 5 are spaces having a substantially circular cross section. With this configuration, the puncture needle can be easily pierced into the discharge port 5, and the drug can be easily mixed in the drug storage unit 4. The cross sections of the medicine container 4 and the discharge port 5 may be polygonal shapes such as an ellipse and a rectangle.

  The medicine storage part 4 is a medicine storage space formed by the medicine storage part forming part 7 a, the lid part 8, and the distribution restriction part 6 of the main body part 7. The medicine container 4 is filled with a medicine 9. The medicine storage part 4 is formed from one end to the other end of the medicine storage part forming part 7a. One end of the medicine storage unit 4 is closed by the flow restriction unit 6, and the other end is closed by the lid unit 8. The medicine storage space 4 may have any shape as long as it has a volume capable of filling a proper amount of the medicine 9 and can mix the medicine in the soft bag 2 and the medicine in the storage space 4. . The medicine container 4 of the present invention does not have a discharge port for directly discharging the medicine 9. With the configuration as described above, the medicine container 4 is restricted from communicating with the inside of the soft bag 2 by the communication restricting portion 6 (fragile portion 6a), and only when the communication restricting portion 6 is broken, Communication is possible.

  The drug 9 filled in the drug container 4 may be any powder, granule or other solid form, liquid form or the like. 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, anti-Parkinson agents, ulcer treatment agents, corticosteroid agents, arrhythmia agents, correction electrolytes, antiviral agents, immunostimulants, and the like. Moreover, although the chemical | medical agent storage part 4 may be a normal pressure, it is good also as a pressure reduction or a vacuum state. As described above, when the medicine container 4 is in a reduced pressure or vacuum state, the effect of preventing the degradation / degradation or the like of the medicine is improved, and when the communication restricting portion 6 is broken, the infusion is sucked and the medicine is more quickly It can be introduced into the storage unit 4. The filling of the medicine into the medicine storage section 4 is performed by filling the medicine from the opening on the lid section 8 side of the forming section 7a and then closing the lid with the lid section 8 under normal pressure or reduced pressure.

  The discharge port 5 is a port for discharging the contents in the soft bag 2 to the outside of the soft bag 2. As shown in FIG. 5, the discharge port 5 includes a discharge port forming portion 7 b and a lid portion 8 of the main body portion 7. The discharge port 5 includes a discharge path formed by the discharge port forming portion 7 b, the lid portion 8, and the communication restriction portion 6. The discharge path is formed from one end to the other end of the discharge port forming portion 7b. One end of the discharge port 5 is closed by the communication restricting portion 6, and the other end is closed by a sealing material 5a through which the discharge needle can be inserted as shown in FIGS. The sealing material 5a is formed of an elastic body. The discharge port 5 may be formed to a length such that the tip of the discharge needle inserted through the sealing material 5 a comes into contact with the communication restricting portion 6. With this configuration, if the discharge needle is inserted before the communication restricting portion 6 is broken, the tip of the needle comes into contact with the communication restricting portion 6, thereby preventing the communication restricting portion 6 from being forgotten to be folded. Note that the discharge port 5 may not include a discharge path.

  As the sealing material 5a, a discharging needle can be pierced. Moreover, it is preferable that the sealing material 5a has a self-occlusion property, and after the needle tube is extracted from the elastic body, the puncture hole is closed to prevent leakage of the chemical solution. Examples of the constituent material of the sealing material include polyolefins such as polyethylene, polypropylene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, and cross-linked ethylene-vinyl acetate copolymer, polyester, polyvinyl chloride, polyurethane, Flexible polymer materials such as polyamide, thermoplastic resins such as polyamide elastomer and polyester elastomer (thermoplastic elastomer), natural rubber, isoprene rubber, silicone rubber, butadiene rubber, various rubber materials such as styrene-butadiene rubber, etc. An elastic material or a combination of any two or more of these materials can be used, and those containing an elastic material are preferable from the viewpoint of sealing performance and resealability.

  As shown in FIGS. 1 and 5, the discharge port 5 is not in communication with the inside of the soft bag 2 when the communication restricting portion 6 is not broken. For this reason, in this state, even if the discharging needle is inserted into the sealing material 5a, the contents inside the soft bag cannot be discharged. When the communication restricting portion 6 is broken, the contents in the soft bag flow into the discharge port 5 through the opening formed by the breakage, so that the contents can be discharged. In the present invention, since the discharge port 5 is formed independently of the medicine container 4, only the solution in the soft bag 2 can be discharged from the discharge port 5, and the medicine 9 in the medicine container 4 cannot be directly discharged. It has become. For this reason, it is safe because the drug 9 in the drug container 4 and the drug solution in the soft bag are not separately administered.

As shown in FIGS. 2 and 5, the communication restricting portion 6 includes a fragile portion 6a that can be broken by a finger break, an operation portion 6b for performing a damaging operation of the fragile portion 6a, and a tapered portion 6d. Yes.
As shown in FIGS. 2 and 5, the fragile portion 6 a is formed by making the thickness of the boundary portion between the end portions of the medicine storage portion 4 and the discharge port 5 and the communication restriction portion 6 thinner than other places. Specifically, in the embodiment shown in FIG. 2 and FIG. 5, it is formed by providing a groove at the boundary. It is preferable that the groove is provided on the entire circumference of the boundary portion. The groove is preferably formed so as to be deeper toward the center of the boundary portion in the axial direction. The cross-sectional shape of the groove is preferably made in a triangular shape, a semi-elliptical shape, a semi-circular shape or the like. Further, the depth of the groove in the embodiment of the present invention is uniform over the entire circumference.

As shown in FIGS. 2 and 5, the operation portion 6b is a supportable portion formed continuously with the fragile portion 6a. The operation part 6b is formed in a flat plate shape and extends on the opposite side to the main body part 7 with respect to the fragile part 6a. Moreover, it is preferable that the anti-slip | skid part 6c is provided in the surface of the operation part 6b. In the embodiment of the present invention, a rib is provided as the anti-slip portion 6c.
As shown in FIG. 7, when the communication restricting portion 6 is bent from the outside of the soft bag 2 to break the fragile portion 6 a, the medicine containing portion 4 is connected to the closed end of the medicine containing portion 4 and the discharge port 5 on the communication restricting portion 6 side. And two openings which connect the discharge port 5 and the inside of the soft bag 2 are formed substantially simultaneously. Then, the medicine in the medicine storage unit 4 moves into the soft bag 2 and is administered after being sufficiently mixed with the chemical solution in the bag 2. It is preferable that the opening formed by the breakage of the fragile portion 6a has an opening area that can sufficiently ensure the communication of the drug solution between the medicine container 4 and the discharge port 5 and the inside of the soft bag 2. The cross-sectional shape of the opening formed by the breakage of the fragile portion 6a is not particularly limited, and examples thereof include an ellipse and a rectangle in addition to a circle.
Therefore, according to the embodiment of the present invention, the drug 9 in the drug container 4 and the drug solution in the soft bag 2 are not administered alone, which is safe.

In the medicine container 3 of the embodiment of the present invention, when the communication restricting portion 6 is broken, the closed ends of the medicine containing portion 4 and the discharge port 5 on the communication restricting portion side are opened almost simultaneously. Instead, the medicine storage unit 4 may be configured to communicate with the soft bag 2 before the discharge port 5.
The distribution regulating unit may have any configuration as long as it opens both the medicine storage unit and the discharge port by a series of opening operations.
Moreover, although the main-body part of the chemical | medical agent container 3 and the communication control part 6 may join another member, it is preferable to form integrally like this Example. Further, the fragile portion can also be formed by forming with a separate member from the center of the boundary portion and controlling the joining force, or by interposing a brittle resin in the boundary portion. Moreover, it is preferable that the main-body part 7 and the communication control part 6 of the chemical | medical agent container 3 are comprised from the hard material, especially a hard resin material. Moreover, by comprising with a hard material, the weak part 6a by the operation of the operation part 6b can be fractured easily and reliably. Moreover, it is preferable that at least the main body portion 7 of the medicine container 3 is made of a transparent or translucent material in order to ensure internal visibility.

Examples of the hard material used for the drug container 3 include hard polyvinyl chloride, polyethylene, polypropylene, polybutadiene, cyclic polyolefin (specifically, ZEONEX (registered trademark, Nippon Zeon Co., Ltd.), APEL (registered trademark, Mitsui Chemicals). Ltd.)), polypropylene, polypropylene homopolymer, polyolefin such as high density polyethylene, polystyrene, poly- (4-methylpentene-1), polycarbonate, ABS resin, acrylic resin, polymethyl methacrylate (PMMA), polyacetal, Polyarylate, polyacrylonitrile, polyvinylidene fluoride, ionomer, acrylonitrile-butadiene-styrene copolymer, polyethylene terephthalate (PET), polybutylene terephthalate (PBT) Una polyester, butadiene - styrene copolymer, various resins such as aromatic or aliphatic polyamide, or is a combination thereof optionally used.
