Description

  The present invention relates to a multi-chamber container capable of preparing and blending drugs.

  Prior to infusion to a patient, a liquid medicine is prepared by mixing and dissolving a solid medicine such as a vitamin or antibiotic in an infusion medicine such as a vial or a soft bag. It has been broken.

  In order to prepare such a drug solution, first, a puncture needle of a syringe is pierced through an elastic stopper such as a vial bottle, and a plunger is pulled to collect an appropriate amount of infusion solution in the vial bottle into a syringe. Next, the collected infusion is transferred to a pre-weighed solid medicine container, and the solid medicine and the infusion are mixed and dissolved to obtain a medicine mixture. This drug mixture is collected by the syringe, the puncture needle of the syringe is pierced through the elastic stopper such as the previous vial, and the plunger is pushed to return the drug mixture to the vial or soft bag. .

  However, the preparation of such a chemical solution has the disadvantage that the operation procedure is complicated, and is particularly inconvenient when rapid infusion is required.

  In addition, preparation of the chemical solution as described above may cause contact with contaminated atmosphere or equipment because a part of the infusion is once taken out and mixed and dissolved in another container. There was a risk of contamination.

  In order to solve such a problem, Japanese Patent Laid-Open No. 4-364851 discloses an inner space of a soft bag as a container capable of aseptically mixing a solid drug and a solution (infusion solution). A container is disclosed that is separated into two by heat-sealing with a seal portion, and contains a solid drug and a solution in each space. When it is necessary to prepare a drug solution, the outside of the container is pressed to break the seal portion, and the solid 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 to alter the solid medicine in the container.

  Alternatively, the seal part may be easily broken by external pressure or impact, and the solid drug and solution may be mixed except when necessary, making it difficult to maintain the stability and safety of the drug. is there.

  Furthermore, since the flexible sheet material generally has a relatively high gas permeability, there are cases where the solid drug may be decomposed or altered by contact with moisture, oxygen or the like due to gas intrusion into the container. Therefore, a portion of the container in which the solid drug is accommodated is double-wrapped with a gas-impermeable packaging material, and an oxygen scavenger and a desiccant are sealed 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.

  The object of the present invention is to mix a solid drug and a liquid such as an infusion solution in a storage container by a simple operation when necessary. An object of the present invention is to provide a multi-chamber container that can prevent alteration, decomposition, etc. of a drug in the container.

  According to the multi-chamber container of the present invention, the space containing each of the infusion agent and the solid medicine is not communicated except when necessary, and the stability and safety of the chemical solution can be maintained.

  In addition, since there is no possibility that a pinhole is formed in the medicine container, gas and moisture do not enter the container, and alteration or decomposition of the medicine can be prevented. And since the packaging material etc. which enclosed the oxygen absorber and the desiccant are unnecessary like the past, the whole container can be reduced in size and conveyance and a preservation | save become easy.

  Further, by operating the communication mechanism from the outside of the multi-chamber container, the infusion agent and the solid drug can be mixed and dissolved, so that the drug solution can be quickly prepared. In addition, since the infusion agent and the like do not come into contact with the outside air during preparation, the chemical solution can be safely prepared without the possibility of contamination with bacteria and foreign substances.

The opening area of the opening can be sufficiently secured without causing a decrease in strength or the like.

Hereinafter, the multi-chamber container of the present invention will be described in detail based on a preferred embodiment shown in the accompanying drawings.
1 is a perspective view showing a first embodiment of the multi-chamber container of the present invention, FIG. 2 is a partial longitudinal sectional view of the multi-chamber container shown in FIG. 1, and FIGS. 3 and 4 are each shown in FIG. It is AA sectional view taken on the line of the communication mechanism of a multi-chamber container. In FIG. 3, the direction perpendicular to the paper surface is defined as “the width direction of the bag 2”.

  As shown in these drawings, the multi-chamber container 1 of the present invention contains a bag 2 made of a soft material having a first space 21 for containing a liquid such as an infusion solution 25 and the like, and a solid medicine inside. Partitioning the medicine container 3 made of a hard material having the second space 33, the first space 21 and the second space 33, and when necessary, the first space 21 and the second space 33 The partition member 4 includes a communication mechanism 5 capable of communicating with the space 33.

Hereinafter, each of these components will be sequentially described.
The bag 2 is formed by forming a sheet material made of a flexible soft material into a tubular shape (tube shape), and sealing the edge of the bag by fusion (thermal fusion, high frequency fusion, etc.) or adhesion. It is obtained by making it into a shape.

  A first space 21 is formed inside the bag 2 and contains an infusion solution 25 (liquid).

  Examples of the infusion solution 25 include physiological saline, electrolyte solution, Ringer's solution, high-calorie infusion solution, glucose solution, and water for injection.

  A suspending portion 7 in which a hole or the like for suspending the multi-chamber container 1 on the hanger may be provided in the seal portion 24 opposite to the opening 22 of the bag 2 in the longitudinal direction.

  As the soft material constituting the bag 2, for example, a resin material is preferable. Thereby, the operation of the communication mechanism 5 described later from the outside of the bag 2 becomes easy.

  Examples of such a soft resin material include polyethylene, polypropylene, polybutadiene, polyolefin such as ethylene-vinyl acetate copolymer (EVA), polyester such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and soft poly. Various thermoplastic elastomers such as vinyl chloride, polyvinylidene chloride, silicone, polyurethane, polyamide elastomer, or any combination thereof (blend resin, polymer alloy, laminate, etc.) can be mentioned, but more preferable soft resin material is soft Polyvinyl chloride is mentioned. This soft polyvinyl chloride has heat resistance that can withstand the high temperatures of autoclave sterilization, and is flexible, so it is easy to handle, has the advantage of being easy to mold and process into bags, and reducing manufacturing costs. .

  In addition, as a constituent material of the bag 2, a soft resin obtained by blending polypropylene with a styrene-butadiene copolymer and softening can be cited, which is excellent in water resistance, heat resistance, flexibility, workability, and reduction in manufacturing cost. It is preferable in that it can be achieved.

  Furthermore, in order to maintain the quality of the infusion solution 25, a film such as an aluminum foil can be further laminated on the bag 2 in order to impart oxygen barrier properties, light shielding properties, and the like.

  In order to provide oxygen barrier properties, a thin film such as a vapor deposition film made of an oxide such as titanium oxide, aluminum oxide, or silicon oxide can be formed on the surface of the bag 2. Even in this case, the transparency of the bag 2 can be maintained, and when the communication operation is performed, the confirmation of the communication state, the mixing / dissolving state of the infusion agent 25 and the solid medicine 31 and the like are easily visible. Is preferred.

  Although the thickness of the sheet material which comprises the bag 2 is not specifically limited, It changes with the constituent material of a sheet material, For example, in the case of a sheet material made from a soft polyvinyl chloride, it is preferable that it is about 20-500 micrometers.

  The opening 22 of the bag 2 is a partition for sealing the opening 22 and partitioning the first space 21 and the second space 33 to separate and store the infusion solution 25 and the solid medicine 31. A member 4 is provided.

  As shown in FIG. 2, the partition member 4 includes a lid part 41 that seals the opening 22 and a joint part 43 that joins the medicine container 3.

  As shown in FIGS. 2 to 4, the lid 41 covers the entire surface of the opening 22 of the bag 2, and the portion where the lid 41 and the opening edge 23 of the bag 2 come into contact is joined by fusion or the like. ing. Therefore, the opening 22 is liquid-tightly sealed by the lid 41.

  The joint portion 43 is provided with steps having different thicknesses on the entire circumference thereof. Thereby, the joining area of the junction part 43 can be enlarged, and the joining property and adhesiveness with the chemical | medical agent storage part 3 improve more.

  The partition member 4 is preferably made of a hard resin material. By using a hard material, it is possible to prevent the partition member 4 from being accidentally broken due to pressure, impact, or the like on the multi-chamber container 1, and the first space 21 and the second space 33 communicating with each other. .

  As a constituent material of the partition member 4, for example, rigid polyvinyl chloride, polyethylene, polypropylene, polyolefin such as polybutadiene, 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), polyester such as polybutylene terephthalate (PBT), butadiene-styrene copolymer, Various resins such as aromatic or aliphatic polyamide, or any combination thereof may be mentioned, but among these, safety is particularly high and adhesion to the bag 2 is excellent. In terms of that, rigid polyvinyl chloride, polyethylene, polypropylene, polyester is preferred.

  In addition, by providing the partition member 4, the range of selection of the material which each comprises the bag 2 and the chemical | medical agent storage part 3 spreads. That is, when the bag 2 and the medicine container 3 are made of different materials, even if their bonding properties are poor, the partition member 4 is interposed to bond them so as to ensure sufficient bonding strength. Alternatively, it can be fused.

  The lid portion 41 has a raised portion 42 that protrudes toward the first space 21 at the center. The raised portion 42 can keep a distance between a later-described lever 51 provided on the raised portion 42 and the opening 22 to some extent, and the operation of the lever 51 can be easily and reliably performed.

  The protruding portion 42 is provided with a communication mechanism 5 that forms an opening and communicates by breaking a part of the partition member 4.

  The communication mechanism 5 is preferably operable from the outside of the bag 2. Thereby, there is no need to open the multi-chamber container 1 or take out the infusion solution 25 for the preparation of the chemical solution, and there is no possibility of contamination of the chemical solution by bacteria or contamination with foreign substances.

  Moreover, the communication mechanism 5 forms the opening 53 by making a part of said partition member 4 break, and makes it communicate. As a result, the communication operation is simple and reliable, and the chemical solution can be easily prepared.

The communication mechanism 5 of the present embodiment is mainly composed of a lever 51 and a breaking portion 52.
As shown in FIG. 3, the lever 51 is provided at the top of the raised portion 42 and protrudes toward the first space 21 with a predetermined inclination angle. The lever 51 has such a length that the tip thereof contacts or approaches the inner surface of the bag 2. Thereby, the operation of the lever 51 from the outside of the flexible bag 2 can be easily and reliably performed.

  Around the base end portion of the lever 51, at least a fracture portion 52 (thin fragile portion) is formed. The broken portion 52 is formed by a groove having a V-shaped cross section extending in the width direction of the bag 2. As shown in FIGS. 3 and 4, when the lever 51 is operated in the X direction (rotating operation about the major axis of the ellipse of the opening 53), the partition member 4 is broken at the breaking portion 52 to form the opening 53. The first space 21 and the second space 33 communicate with each other. As described above, since the partition member 4 is made of a hard material, the opening 53 once formed retains its shape.

  In addition, the fracture | rupture part 52 of a present Example is comprised by one pair of groove | channels provided in the 1st space 21 side and the 2nd space 33 side so that it may become symmetrical across the wall of the protruding part 42. However, it is also possible to provide a groove only on either the first space 21 side or the second space 33 side.

  The opening 53 formed by the rupture has an elliptical long hole shape having a long axis, and has an opening area that can sufficiently ensure the flow of the liquid between the first space 21 and the second space 33. It is preferable to have. In this way, by sufficiently increasing the opening area of the opening 53, the infusion agent 25 in the first space 21 can be quickly flowed into the second space 33, and dissolution / mixing of the solid medicine 31 can be performed. It can be done quickly and efficiently.

  Furthermore, since the opening 53 is mainly composed of an elliptical long hole having a long axis in the width direction of the bag 2, the opening area of the opening 53 in the flat bag 2 is reduced in strength. And can be secured sufficiently.

  In addition, the communication mechanism 5 is preferably made of a hard resin material, like the partition member 4. Thereby, formation is easy and operation of the lever 51 is facilitated, and the fractured portion 52 can be reliably fractured.

  In the illustrated example, the communication mechanism 5 is formed integrally with the partition member 4, but these may be separate members.

  As described above, the medicine container 3 is hermetically joined at the joint 43 on the side opposite to the side where the bag 2 of the partition member 4 is adjacent.

  This medicine container 3 is made of a hard material. As a result, since the medicine container 3 is not greatly deformed by external pressure, the solid medicine 31 and the sheet material constituting the medicine container 3 slidably come into contact with the sheet material as in the prior art. Defects such as pinholes are not generated. Therefore, gas (water vapor, oxygen, etc.) does not enter the second space 33 from the pinhole, and the solid medicine 31 can be prevented from being altered or decomposed.

  As the hard material constituting the medicine container 3, the same materials as those exemplified for the partition member 4 can be used. Among them, for example, resins such as polyethylene terephthalate (PET), polyacrylonitrile, polyvinylidene fluoride, etc. Material is preferred. Such a material has low gas permeability such as oxygen, carbon dioxide, water vapor and the like, and can prevent the deterioration and decomposition of the solid drug 31 in the drug container 3 at a higher level, and can perform quality control more strictly. it can.

Further, a resin material having relatively gas permeability such as polypropylene and cyclic polyolefin can be used. In this case, a layer made of an oxide such as SiO ₂ , Al ₂ O ₃ , TiO ₂ (gas barrier layer) is formed on the surface by means of vapor deposition, sputtering, etc. The permeability can be improved.

  Moreover, it is preferable that the said bag 2 and the said chemical | medical agent storage part 3 are comprised with the resin material from which a composition or a characteristic differs, respectively. With such a configuration, the bag 2 can be made of a soft material, and the medicine container 3 can be made of a hard material, and the selection of each material can be widened as described above.

  A solid medicine 31 is contained in the second space 33 in the medicine container 3. This solid drug 31 is mixed and dissolved with the infusion solution 25. For example, antibiotics, vitamins (general vitamins), various amino acids, antithrombotic agents such as heparin, insulin, antitumor agents, analgesics Agents, cardiotonic agents, intravenous anesthetics, anti-parkinsonian agents, ulcer treatment agents, corticosteroid agents, arrhythmic agents, correction electrolytes, antiviral agents, immunostimulants, and the like.

  The medicine container 3 has a cross-sectional shape and size substantially equal to those of the bag 2 and the partition member 4 described above. As shown in FIG. 2, a step portion that can be fitted to the joint portion 43 is formed on the entire periphery of the portion of the medicine container 3 that is joined to the partition member 4. Thereby, the chemical | medical agent storage part 3 and the partition member 4 are joined with higher airtightness.

Further, the medicine container 3 has a tapered portion that decreases in diameter toward the bottom 32. A discharge port 6 for discharging the chemical solution is provided at the bottom 32 positioned at the end of the tapered portion. The outlet 6 is sealed by inserting an elastic body 61 and attaching a cap 62 from above. As a result, the second space 33 is hermetically sealed, the chemical solution does not leak to the outside, and O ₂ gas, CO ₂ gas, water vapor, or microorganisms such as bacteria enter the inside. There is no need to do.

  The elastic body 61 is preferably made of an elastic material that can puncture a needle tube. By comprising an elastic material, it can be inserted into the discharge port 6, and the sealing performance of the second space 33 can be made more reliable. Furthermore, when the needle tube is punctured, leakage of the chemical solution from the puncture hole can be prevented.

  As a constituent material of the elastic body 61, a polymer material having flexibility is preferable. For example, polyethylene, polypropylene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, and cross-linked ethylene-vinyl acetate. Examples thereof include polyolefins such as copolymers, thermoplastic resins such as polyester, polyvinyl chloride, polyurethane, polyamide and polyamide elastomer, and elastic materials such as natural rubber and silicone rubber.

  The cap 62 has a function of tightly fixing the elastic body 61 inserted into the discharge port 6 and the bottom 32 of the medicine container 3.

  The cap 62 is provided with a hole 63 for exposing the elastic body 61, and a needle tube can be pierced into the elastic body 61 from the hole 63.

  The material of the cap 62 is not particularly limited, and examples thereof include a resin material and a metal material.

  5 and 6 are partial longitudinal sectional views showing a second embodiment of the multi-chamber container of the present invention. The multi-chamber container shown in the figure has the same configuration as the multi-chamber container 1 shown in FIGS. 3 and 4 except that the configuration of the communication mechanism 5 is different.

  When the partition member 4 is broken by the communication operation, the lever 51 constituting the communication mechanism 5 of the present embodiment is separated from the communication mechanism 5 at the breaking portion 52 and becomes a broken piece 55.

  This broken piece 55 preferably has a specific gravity smaller than that of the infusion solution 25 accommodated in the first space 21. As a result, the broken piece 55 floats to the liquid level in the first space 21, and therefore, when the multi-chamber container 1 is in a state where the discharge port 6 faces downward (for example, when suspended by the suspension part 7). Etc.), and there is no possibility that the opening 53 is blocked.

  In this case, the specific gravity of the material itself of the broken piece 55 is not limited to that satisfying the above condition. For example, as shown in FIG. 6, the hollow piece 56 formed of a closed space is formed in a part of the broken piece 55. It may satisfy the condition.

  Thereby, when selecting the material of the broken piece 55, there is no restriction due to specific gravity, the range of selection is widened, and the direction of the broken piece 55 when it floats due to the formation position, size, etc. of the hollow portion 56 Sex can also be controlled.

  The lever 51 is preferably provided with a locking projection 54 that protrudes in a direction different from the direction in which the lever 51 protrudes. Thereby, the broken piece 55 can have a shape and a size that cannot pass through the opening 53. Therefore, even when the discharge port 6 is directed vertically upward, or even when the broken piece 55 sinks in the infusate 25, the broken piece 55 does not pass through the opening 53 and obstruct the flow of the infusate 25. Preparation and stirring can be performed quickly.

  The number and shape of the locking protrusions 54 are not limited to those of the present embodiment, and for example, a plurality of protrusions may be provided.

  The fracture portion 52 is formed by a groove having a V-shaped cross section provided along the outline of the opening 53. Accordingly, the lever 51 can be broken by performing at least one reciprocating motion, and can be separated from the partition member 4 into a broken piece 55.

Next, an example of the manufacturing method (assembly method) of the multi-chamber container 1 of this invention is demonstrated.
First, a kit (bag 2, partition member 4 (including the communication mechanism 5), and medicine container 3) constituting the multi-chamber container 1 having a predetermined size and capacity is formed.

  After the bag 2 and the partition member 4 are joined at the lid portion 41, an infusion solution 25 is injected, the injection port is sealed, and then sterilization is performed by autoclave sterilization. On the other hand, a predetermined amount of drug 31 is stored in the drug container 3.

  The sterilized bag 2 and the partition member 4 are joined at the joint portion 43 between the medicine container 3 and the partition member 4 to obtain the multi-chamber container 1.

  Here, as a method for joining the partition member 4 to the bag 2 and the medicine container 3, methods such as ultrasonic sealing, heat fusion, fitting, and joining using various adhesives can be used.

  Further, as another method, the multi-chamber container 1 is formed by joining the bag 2, the partition member 4, and the medicine container 3 by, for example, the methods exemplified above.

  Next, the infusion solution 25 is injected into the bag 2 and the injection port is sealed, followed by sterilization. On the other hand, a method in which the solid medicine 31 is aseptically sealed from the discharge port 6 of the medicine container 3, and then the elastic body 61 is inserted into the discharge port 6, and the cap 62 is covered from above to seal the discharge port 6. Is also possible.

  When the communication operation of the thus obtained multi-chamber container 1 is performed, the lever 51 is turned by hand from the outside of the bag 2. At that time, stress acts on the fractured portion 52 provided at the base of the lever 51. Further, when a force is applied to the lever 51, the partition member 4 is broken at the breaking portion 52, and an opening 53 is formed. The lever 51 may be rotated by reciprocating the lever 51 at least once.

  As described above, the opening 53 has a diameter that can sufficiently ensure the flow of the liquid, so that the infusion agent 25 accommodated in the first space 21 can be quickly transferred to the second space 33. The infusion solution 25 and the solid drug 31 can be efficiently mixed and dissolved. At this time, the bag 2 may be compressed or shaken from the outside in order to promote the circulation.

  After the solid drug 31 is completely dissolved, the multi-chamber container 1 is shaken to stir the drug solution uniformly, and the preparation of the drug solution is completed. When the multi-chamber container 1 is shaken, the broken piece 55 moves up and down in the first space 21 due to its buoyancy, so that it can function as a stirrer, and the chemical solution can be prepared more efficiently.

  When the preparation of the medicinal solution is completed, infusion is performed through the tube according to a conventional method by puncturing the elastic stopper 61 with a needle of an infusion tube.

  As described above, the multi-chamber container of the present invention has been described with reference to the drawings. However, the present invention is not limited to these, and for example, the shape and structure of the communication mechanism has a lever and a fracture portion as illustrated. It is not limited, and the communication method is not limited to that by breakage.
