Description

The present invention relates to a medical multi-chamber container provided with a plurality of storage portions for individually storing various unstable drugs (liquids, powders or solids) that change with time when mixed.

Some of the drugs given to patients by intravenous injection are unstable drugs that, when premixed, cause unwanted changes over time. For example, in the case of amino acid infusion and glucose infusion, the Maillard reaction causes the mixture to turn brown. Further, in the case of a fat emulsion and an electrolyte solution, the fat content aggregates, and in the case of a phosphoric acid-containing solution and a calcium-containing solution, calcium phosphate precipitates.

As a container for storing these drugs, a medical multi-chamber container for individually storing a plurality of types of drug components before mixing is known (see Patent Document 1). As described in Patent Document 1, such a multi-chamber container includes a plurality of storage portions for individually storing each drug and a partition sealing portion for partitioning the plurality of storage portions. Since the joint strength of the partition sealing portion is set low, when pressure is applied from the outside of one of the plurality of storage portions, the partition sealing portion is opened due to the increase in pressure inside the housing portion, and the plurality of storage portions are opened. Each other opens. This allows the individually stored agents to be mixed and administered to the patient before they change over time.

JP-A-2002-136570

In the conventional medical multi-chamber container as described above, when the pressure applied to the storage portion is not sufficient to open the partition sealing portion, or when the operation of applying pressure to the storage portion is not performed, the operation of applying pressure to the storage portion is not performed. Since the partition sealing portion is not opened and the plurality of storage portions are not opened, there is a risk that the individually stored drugs may be administered to the patient without being mixed.

When the pressure applied to the storage portion is not sufficient, it is conceivable to significantly reduce the joint strength of the partition sealing portion so that the plurality of storage portions can be easily opened. However, if the joint strength of the weakly sealed part for partitioning is lowered from the aspect of easy opening, the weakly sealed part for partitioning will be opened when there is no intention such as an impact during transportation, and chemicals will be mixed and changes over time will occur. There is a risk.

The present invention has been made in view of the above problems, and the partition sealing portion of the container body can be reliably and easily opened, while the medical use is difficult to open due to an impact during transportation or the like. The purpose is to provide a multi-chamber container.

As a result of diligent studies on the structure of the medical multi-chamber container, the present inventors have devised a medical multi-chamber container that can solve the above problems. That is, the medical multi-chamber container according to the present invention is a bag-shaped container body composed of a first film and a second film facing the first film, and the first film and the second film. A container body in which a partition sealing portion for partitioning the inside into a first storage portion and a second storage portion is formed by joining the film so as to be peelable, and a second storage that is attached to the container body. A first coating film that includes a drug discharging portion that communicates with the portion and a coating member that covers at least a part of the container body, and the coating member is bonded to the first film and the second film, respectively. And a second coating film, the first coating film and the second coating film have a strength equal to or higher than the bonding strength of the partition sealing portion to the first film and the second film on the partition sealing portion. It is bonded with a bonding strength, and the first coating film and the second coating film are detachably bonded to the first film and the second film on the second storage portion.

According to the medical multi-chamber container of the present invention, since the joint strength between the covering member and the partition sealing portion is equal to or higher than the bonding strength of the partition sealing portion, the covering member is used to start using the multi-chamber container. When the container is separated from at least a part of the container body and peeled off, the partition sealing portion is also opened by the tensile force, and the two storage portions are surely opened. As a result, even if the pressure applied to the storage portion is not sufficient or the operation of applying pressure to the storage portion is not performed, the individually stored drugs can be reliably mixed and administered to the patient. It will be possible.

Further, in the conventional medical multi-chamber container, the drug discharge part is covered with a peel seal so that the sterile state is maintained until the time of use. However, when using this multi-chamber container, the user is asked. There is also a problem that the work of administering the drug is troublesome because the peel seal must be peeled off at the same time as opening the partition sealing portion.

On the other hand, in the medical multi-chamber container in which the drug discharge part is also covered with a covering member, the peel seal that has been conventionally applied becomes unnecessary, and the drug discharge part is exposed and sealed for partitioning by simply peeling off the covering member. The part can be opened at the same time, and the labor of drug administration work can be reduced.

The covering member may be provided only on a part of the container body from the viewpoint of resource saving, but the covering member may cover the entire container body. This makes it possible to omit the exterior that has been applied to the conventional medical multi-chamber container. This contributes to resource saving and eliminates the need to dispose of the exterior, which leads to a reduction in the labor of drug administration work.

Further, the first coating film and the second coating film can be peeled off from the first film and the second film on the second storage portion with a bonding strength equal to or higher than the bonding strength of the partition sealing portion. It is preferable that they are joined. As a result, the opening of the partition sealing portion is started when the covering member is peeled off from the second storage portion, so that the opening can be performed even more reliably.

A hole for inserting a hook may be formed at the end of the first coating film and the second coating film on the drug discharging portion side. In this hole, the first coating film and the second coating film are peeled off from the drug discharging section and the second storage section of the container body, and the drug is discharged in a state where the partition sealing portion is folded back to the opposite side. It is arranged outside the end of the container body on the opposite side of the portion. As a result, the medical multi-chamber container can be hung on the hook of the so-called drip stand. According to this configuration, it is possible to perform a series of operations from peeling of the covering member to starting the use of the medical multi-chamber container hung on the drip stand, and the drug can be easily administered.

Various methods of bonding the first coating film and the second coating film to the first film and the second film can be considered, but when the surface layer of each film is a thermoplastic resin layer or the entire film. When is made of a thermoplastic resin, it is effective to use heat fusion. This is because heat fusion is a simple method of simply applying heat, and the bonding strength can be easily controlled by adjusting the heating temperature. Further, heat fusion can be performed by utilizing the temperature of high-pressure steam sterilization usually performed at the final stage of the manufacturing process of the medical multi-chamber container. In this case, there is an advantage that the joining step related to the covering member can be omitted from the manufacturing process of the multi-chamber container. Further, the inner surface of the covering member and the outer surface of the container body can be closely joined by high pressure.

Various forms of the first coating film and the second coating film can be considered, and for example, it may constitute a blister package that covers the entire medical multi-chamber container.

According to the present invention, it is possible to provide a medical multi-chamber container in which the partition sealing portion of the container body is easy to open when the medical multi-chamber container is used, while it is difficult to open due to an impact during transportation or the like. It will be possible. In particular, in a medical multi-chamber container in which the covering member also covers the drug discharging portion, the peel seal becomes unnecessary. This is preferable because it is possible to perform a series of operations from the exposure of the drug discharging portion to the opening of the partition sealing portion, and the drug administration work becomes easy.

Hereinafter, embodiments of the medical multi-chamber container according to the present invention will be described with reference to the drawings.

FIG. 1 is a schematic plan view showing an embodiment of a medical multi-chamber container, and FIG. 2 is a schematic cross-sectional view taken along the line II-II of FIG. As shown in these figures, the medical multi-chamber container 10 includes a rectangular container body 12 and a drug discharge unit 14 attached to the container body 12. Further, the medical multi-chamber container 10 further includes a covering member 22, and the covering member 22 covers the container body 12 and the drug discharging section 14.

The container body 12 is formed in a bag shape by joining the peripheral edges 30 of the two films (the first film 12a and the second film 12b) over the entire circumference thereof. As a result, the drug can be stored in the container body 12.

In the present embodiment, the film constituting the container body 12 is two single-layer or multi-layer films having the same shape and the same dimensions, and the inner surface inside the container body 12 is heated by polyethylene, polypropylene, polystyrene, or the like. It is preferably a plastic resin. By using a thermoplastic resin, the films can be bonded to each other by heat fusion. Further, it is preferable that the outer surface of the container body 12 is also made of a thermoplastic resin such as polyethylene, polypropylene, or polystyrene. As a result, the outer surface of the container body 12 and the inner surface of the covering member 22 can be joined by heat fusion by means such as high-pressure steam sterilization described later. It is preferable that at least the inner surface of the film constituting the container body 12 has chemical resistance and the film as a whole has flexibility.

As the film constituting the container body 12, a film made of another material having no thermoplasticity can also be used. In this case, the peripheral edge portion 30 may be joined by another method such as using an adhesive.

The container body 12 has a rectangular shape in the present embodiment, and is arranged so that the longitudinal direction thereof is the vertical direction (vertical direction) of FIG. Hereinafter, the vertical relationship of the container body 12 may be described with reference to the state shown in FIG.

A partition sealing portion 28 that extends in the left-right lateral direction of FIG. 1 is formed at a substantially central portion of the container body 12 in the vertical direction. The partition sealing portion 28 divides the internal space of the container body 12 into an upper space (hereinafter, “first storage portion 24”) and a lower space (hereinafter, “second storage portion 26”). This makes it possible to store two or more kinds of drugs that are not suitable for mixing or dissolving in advance in the container body 12. For example, various drugs that need to be isolated because they cause a brown change due to the Maillard reaction can be encapsulated. Specifically, one storage portion 24 or 26 contains a solution containing an amino acid, and the other storage portion 26. Alternatively, a solution containing glucose can be stored in 24. Further, not only the liquid drug but also the solid or powder drug may be stored.

The partition sealing portion 28 is formed by heat-sealing the two films constituting the container body 12. The bonding strength of the partition sealing portion 28 is made smaller than the bonding strength of the peripheral edge portion 30 by adjusting the fusion time, temperature, and the like.

The drug discharge section 14 is connected to the end of the container body 12 on the second storage section 26 side. The drug discharge unit 14 is composed of a drug discharge pipe 16 having a passage through which the drug passes, and a rubber stopper 18 for closing the drug discharge pipe 16. Here, when the medical multi-chamber container 10 is used (after the partition sealing portion 28 is opened), the drug in the container body 12 is administered to the patient by inserting the piercing needle into the rubber stopper 18. It will be possible.

As shown in FIGS. 1 and 2, the covering member 22 covers the entire container body 12 and the drug discharging section 14. In the present embodiment, the coating member 22 is made of a single-layer or multi-layer coating film, which is folded in two and used as the first coating film 22a on the front side and the second coating film 22b on the back side. ing. These coating films 22a and 22b have a rectangular shape larger than that of the container body 12 and have substantially the same dimensions. The container body 12 and the drug discharge section 14 are sandwiched between these coating films 22a and 22b, and the container body 12 and the drug discharge section 14 are sealed by joining the covering films 22a and 22b over the entire circumference of the peripheral edge portion 32. Has been done.

In the illustrated embodiment, the covering member 22 has flexibility and is in close contact with the outer surfaces of the container main body 12 and the drug discharging portion 14 by vacuum packaging that sucks air between the covering member 22 and the container main body 12. ing. Further, the covering member 22 is joined to substantially the entire container body 12 (the outer surface of the first storage portion 24, the partition sealing portion 28, and the second storage portion 26). The joint strength at each site will be described later.

The bonding may be performed by an adhesive or the like, but is preferably by heat fusion. Therefore, it is preferable that at least the inner surfaces of the films 22a and 22b constituting the covering member 22 are made of a thermoplastic resin such as polyethylene, polypropylene, or polystyrene, which is easily fused with the resin of the container body 12 by heat. In particular, the resin used for the outer surfaces of the films 12a and 12b constituting the container body 12 and the resin used for the inner surfaces of the coating films 22a and 22b constituting the coating member 22 may be made of a resin having a relatively low melting point. preferable. As a result, the outer surfaces of the films 12a and 12b forming the container body 12 and the coating forming the covering member 22 are applied to the medical multi-chamber container 10 by the heat of high-pressure steam sterilization usually applied at the final stage of the manufacturing process. It is also possible to join the inner surfaces of the films 22a and 22b.

In the medical multi-chamber container 10 of the present embodiment, the thermoplastic resin contained in the coating films 22a and 22b forming the inner surface of the covering member 22 and the heat contained in the outer surfaces of the films 12a and 12b forming the container body 12 It is also preferable that the thermoplastic resin is the same resin such as polyethylene, while the thermoplastic resin contained in the inner surfaces of the films 12a and 12b constituting the container body 12 is a mixture of polypropylene and polyethylene. By setting the temperature of high-pressure steam sterilization, which is usually performed in the final stage of the manufacturing process of the medical multi-chamber container 10, higher than the melting point of polyethylene and lower than the melting point of polypropylene, the same resin such as polyethylene can be obtained by high-pressure steam sterilization. The inner surface of the covering member 22 and the outer surface of the container body 12 can be tightly bonded, and the bonding strength is higher than that of the partition sealing portion 28 whose bonding strength is lowered by a mixture of polypropylene and polyethylene. Can be done.

In the medical multi-chamber container 10 of the present embodiment, since the drug discharging section 14 is also covered by the covering member 22, the upper surface of the rubber stopper 18 of the drug discharging section 14 is covered from the viewpoint of hygiene. The peel seal normally used for is not required. Further, since the drug discharge portion 14 is covered with the covering member 22 at the stage before use, it is possible to prevent the plurality of storage portions 24 and 26 from being used before opening.

The films 22a and 22b of the covering member 22 preferably have a light-shielding property, a gas barrier property, and a water vapor barrier property. Further, as can be understood from FIG. 2, depending on the shapes of the container body 12 and the drug discharging section 14 and the properties of the films 22a and 22b of the covering member 22, the covering member 22 and the container body 12 and the drug discharging section 14 Spaces may be formed between them. In such a case, an oxygen absorber or a water absorbent may be sealed in this space. As a result, deterioration can be suppressed even when the chemical in the container body 12 is a component that is deteriorated by oxygen or water.

Next, a method of using the medical multi-chamber container of the present embodiment will be described.

FIG. 3 is a schematic cross-sectional view showing an operation when the covering member 22 is peeled off from the container body 12. As shown in FIG. 3, when the medical multi-chamber container 10 is started to be used, the covering member 22 is moved from the drug discharge section 14 side to the first storage section 24 side which is not adjacent to the drug discharge section 14. The coating films 22a and 22b on both sides are peeled off. As shown in FIGS. 1 and 2, a knob portion 34 is formed on the peripheral edge portion 32 of the coating film (front side, 22a) of the covering member 22. Therefore, by gripping the end portion 36 and the knob portion 34 of the covering film (back side, 22b), the covering member 22 can be easily peeled off.

Here, the joint strength between the covering member 22 and the container body 12 will be described in detail. The first coating film 22a and the second coating film 22b of the covering member 22 are attached to the first film 12a and the second film 12b on the partition sealing portion 28, and the first coating portion 28 of the partition sealing portion 28 is attached. The film 12a and the second film 12b are bonded with a bonding strength equal to or higher than the bonding strength. As shown in FIG. 3, when the covering member 22 is separated from the drug discharging portion 14 and the container body 12 and peeled off in order to start using the multi-chamber container 10, the partition sealing portion 28 is also formed by the tensile forces F and F. It is opened and the two storage portions 24 and 26 are reliably opened. Therefore, it is possible to administer to the patient after the drugs individually stored in the two storage units 24 and 26 are surely mixed. The first coating film 22a and the second coating film 22b are higher than the bonding strength of the partition sealing portion 28 to the first film 12a and the second film 12b on the partition sealing portion 28. It is preferable that the partition sealing portion 28 is joined with a joining strength from the viewpoint of more reliably opening the partition sealing portion 28.

Further, the first coating film 22a and the second coating film 22b of the covering member 22 are detachably joined to the first film 12a and the second film 12b on the second storage portion 26, and are peeled off. If possible, the joint strength may be any strength. However, the first coating film 22a and the second coating film 22b of the covering member 22 have a bonding strength equal to or higher than the bonding strength of the partition sealing portion 28, and the first coating film 12a on the second storage portion 26 And it is preferable that it is peelably bonded to the second film 12b. As a result, the partition sealing portion 28 is started to be opened by the operation of peeling the covering member 22 from the second storage portion 26, so that the opening can be performed even more reliably. The first coating film 22a and the second coating film 22b are higher than the bonding strength of the partition sealing portion 28 to the first film 12a and the second film 12b on the second storage portion 26. It is more preferable that they are joined with a joining strength.

Further, the bonding strength between the first coating film 22a and the second coating film 22b of the covering member 22 and the first film 12a and the second film 12b on the first storage portion 24 is the partition sealing. From the viewpoint of opening the part 28, there is no particular limitation. However, from the viewpoint of preventing the container body 12 from peeling off from the covering member 22 and falling due to a load such as a chemical when the multi-chamber container 10 is suspended from the drip stand, the covering films 22a and 22b of the covering member 22 are prevented. And the films 12a and 12b on the first storage portion 24 are preferably joined with a joining strength that does not peel off due to a load such as a chemical, and may be joined so as not to be peeled off.

As shown in FIG. 3, the first coating film 22a and the second coating film 22b on both sides of the covering member 22 can be prevented from being completely peeled off from the container body 12. In medical institutions, the treatment of medical waste is strict and the sorting is thorough. However, in the case of the multi-chamber container 10 of the present embodiment, since the container body 12 and the covering member 22 are integrated, once. It is highly convenient in that it can be disposed of at the same time and the labor of sorting processing is reduced.

FIG. 4 is a schematic cross-sectional view showing a state of the medical multi-chamber container when used. As shown in FIG. 4, the first coating film 22a and the second coating film 22b of the coating member 22 peeled off from the drug discharge portion 14 side are joined to the outer surface side of the container body 12 when the container body 12 is coated. The inner surface is inverted by being folded around the partition sealing portion 28 to become the outer surface. Further, the outer surface of the container body 12 at the time of coating is similarly folded back to become an inner surface, and the outer surface of the first coating film 22a and the second coating film 22b covering the first storage portion 24 side. Overlap with.

As shown in FIG. 4, the first coating film 22a and the second coating film 22b are removed from the first film 12a and the second film 12b on the drug discharge section 14 and the second storage section 26 of the container body 12. In a state where the film is peeled off and folded back to the opposite side with the partition sealing portion 28 as the center, a hole 38 for inserting a hook is formed on the outer side of the end portion of the container body 12 on the opposite side of the drug discharging portion 14. The hook 40 is inserted into the hole 38. As shown in FIG. 1, the hole 38 is formed at the end of the first coating film 22a and the second coating film 22b of the covering member 22 on the drug discharging portion 14 side. As a result, the medical multi-chamber container 10 can be hung on the hook 40 of the so-called drip stand. As described above, according to the medical multi-chamber container 10 of the present embodiment, it is possible to perform a series of operations from the peeling of the covering member 22 to the start of use by hanging it on the drip stand, and the drug can be easily administered. be able to. In the conventional multi-chamber container, for example, if the partition sealing portion is left unattended during the opening operation of the partition sealing portion, the partition sealing portion is opened and the chemicals are mixed or changed with time. According to the chamber container, the use can be started by a series of operations, so that it is easy to prevent the container from being left unattended during the opening operation or after the opening operation.

FIG. 5 is a schematic cross-sectional view showing a modified example of the medical multi-chamber container 10b. As shown in FIG. 5, the first coating film 22a and the second coating film 22b of the covering member 22 are the first film 12a on the partition sealing portion 28 and the second storage portion 26 of the container body 12. And may only be bonded to the second film 12b, or may only be bonded to only the first film 12a and the second film 12b on the partition sealing portion 28. For example, when the covering member 22 is joined to the container body 12 that has been sterilized by high pressure steam, the amount of adhesive used can be reduced if the joint portion between the two is small. In the medical double-chamber container 10b of such a modified example, the space between the covering member 22 and the container body 12 and the drug discharge portion 14 is wider than that of the medical double-chamber container 10 shown in FIG. Since there is a tendency, it is preferable to enclose the oxygen absorber or the water absorber A in order to suppress the deterioration of the chemical in the container body 12. Further, from the viewpoint of preventing the medical multi-chamber container 10b of FIG. 5 from falling when suspended from the drip stand, the first coating film 22a and the second coating film 22b of the covering member 22 and the partition sealing portion 28 are above.
