Description

  The present invention relates to a medical multi-chamber container provided with a plurality of storage units that individually store various unstable drugs (solutions, powders, or solid agents) that change with time when mixed.

  Among drugs administered to patients by intravenous injection, there are unstable drugs that cause undesirable changes over time when premixed. For example, in the case of an amino acid infusion and a glucose infusion, the mixed solution browns due to the Maillard reaction. In the case of a fat emulsion and an electrolyte solution, fat is aggregated, and in the case of a phosphoric acid-containing solution and a calcium-containing solution, precipitation of calcium phosphate occurs.

  As a container for storing these drugs, there is known a medical multi-chamber container that individually stores a plurality of types of drug components before mixing (see Patent Document 1). As such a multi-chamber container, as disclosed in Patent Document 1, there is a container including a plurality of storage portions for individually storing each medicine and a partition sealing portion for partitioning the plurality of storage portions. Since the bonding strength of the partition sealing portion is set low, when pressure is applied from one outer side of the plurality of storage portions, the partition sealing portion is opened due to an increase in pressure in the storage portion, and the plurality of storage portions Opening each other. As a result, the individually stored medicines are mixed and can be administered to the patient before a change with time occurs.

JP 2002-136570 A

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

  In the case where the pressure applied to the storage portion is not sufficient, it is conceivable to significantly reduce the bonding strength of the partition sealing portion so that the plurality of storage portions can be easily opened. However, if the bonding strength of the partition weak seal part is lowered from the easy-opening surface, the partition weak seal part is opened when an impact such as an impact during transportation is not intended, and mixing of the medicine or a change over time occurs. There is a fear.

  The present invention has been made in view of the above-described problems, and can reliably and easily open the partition sealing portion of the container body, while being difficult to open due to impact during transportation. The object is to provide a multi-chamber container.

  As a result of intensive studies on the structure of a medical multi-chamber container, the present inventors have devised a medical multi-chamber container that can solve the above-described problems. That is, the medical multi-chamber container according to the present invention is a bag-like 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 main body in which a partition sealing portion is formed to partition the inside into a first storage portion and a second storage portion by releasably joining the film, and the second storage is attached to the container main body. The first covering film is provided with a medicine discharge portion communicating with the portion and a covering member that covers at least a part of the container body, and the covering member is bonded to the first film and the second film, respectively. And the second covering film, the first covering film and the second covering film are 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. Bonded with bonding strength Ri, the first coating film and the second coating film, those which are releasably joined to the first film and second film on the second housing portion.

  According to the medical multi-chamber container of the present invention, since the bonding 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 the use of the multi-chamber container. When the container is separated from at least a part of the container body and peeled, the partition sealing part is also opened by the tensile force, and the two storage parts are reliably opened. Thereby, even when the pressure applied to the storage unit is not sufficient or the operation of applying pressure to the storage unit is not performed, the individually stored medicines can be reliably mixed and administered to the patient. It becomes possible.

  In addition, the conventional medical multi-chamber container is designed so that the medicine discharge part is covered with a peel seal and is kept in a sterile state until use, but when using this multi-chamber container, the user There is also a problem that it takes time and labor to administer the medicine, since the partition sealing portion must be opened and the peel seal must be peeled off.

  On the other hand, in the medical multi-chamber container in which the medicine discharge part is also covered with the covering member, the peel seal which has been conventionally applied becomes unnecessary, and the exposure of the medicine discharge part and the sealing for partitioning can be performed only by peeling the covering member. The opening of the part can be performed at the same time, and the labor of the 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. Thereby, it becomes possible to omit the exterior which was provided with respect to the conventional medical multi-chamber container. This contributes to resource saving and also eliminates the need for disposal of the exterior, leading to a reduction in labor for drug administration.

  In addition, the first cover film and the second cover 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 it is joined. Thereby, since the opening of the sealing part for a partition is started when the coating | coated member is peeled from the 2nd accommodating part, it can open more reliably.

  You may form the hole for hook insertion in the edge part by the side of a chemical | medical agent discharge part of a 1st coating film and a 2nd coating film. In the state where the first cover film and the second cover film are peeled off from the drug discharge part and the second storage part of the container body and folded back to the opposite side with the partition sealing part as the center, this hole It arrange | positions outside the edge part of the container main body on the opposite side to a part. Thereby, this medical multi-chamber container can be hung on the hook of a so-called drip stand. According to this configuration, it is possible to perform a series of operations from the peeling of the covering member to the start of the use of the medical multi-chamber container suspended from the drip stand, and the drug administration can be easily performed.

  Various bonding methods of the first coated film and the second coated film to the first film and the second film are conceivable. When the surface layer of each film is a thermoplastic resin layer, or the whole of each film. When is made of a thermoplastic resin, it is effective to use heat fusion. This is because heat fusion is a simple method in which only heat is applied, and the bonding strength can be easily controlled by adjusting the heating temperature. Further, the heat fusion can be performed by utilizing the temperature of high-pressure steam sterilization that is usually performed in the final stage of the manufacturing process of the medical multi-chamber container. In this case, there exists an advantage that the joining process which concerns on a coating | coated member can be omitted from the manufacturing process of a multi-chamber container. Further, the inner surface of the covering member and the outer surface of the container body can be tightly joined by high pressure.

  In addition, the form of the 1st coating film and the 2nd coating film is considered variously, For example, you may comprise the blister packaging which coat | covers the whole 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 during use of the medical multi-chamber container, but is difficult to open due to impact during transportation. It becomes possible. In particular, in a medical multi-chamber container in which the covering member also covers the medicine discharge portion, no peel seal is required. This is preferable because it can be performed by a series of operations from the exposure of the medicine discharge section to the opening of the partition sealing section, and the medicine administration work is facilitated.

  Hereinafter, embodiments of a 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 line II-II in FIG. As shown in these drawings, the medical multi-chamber container 10 includes a rectangular container main body 12 and a medicine discharge section 14 attached to the container main body 12. Further, the medical multi-chamber container 10 further includes a covering member 22 that covers the container main body 12 and the medicine discharge portion 14.

  The container main body 12 is configured in a bag shape by joining the peripheral portions 30 of two films (the first film 12a and the second film 12b) over the entire circumference. Thereby, a medicine can be stored in the container body 12.

  In this embodiment, the film constituting the container body 12 is a single-layer or multi-layer film having the same shape and the same dimensions, and the inner surface inside the container body 12 is a heat such as polyethylene, polypropylene, polystyrene, or the like. A plastic resin is preferred. By using a thermoplastic resin, the films can be joined by heat fusion. Moreover, it is preferable that the outer surface which is the outer side of the container main body 12 is also thermoplastic resins, such as polyethylene, a polypropylene, a polystyrene. Thereby, the outer surface of the container main body 12 and the inner surface of the covering member 22 can be joined by thermal 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 main body 12 has chemical resistance, and the film as a whole has flexibility.

  In addition, as a film which comprises the container main body 12, the film which consists of another material which does not have thermoplasticity can also be used. In this case, what is necessary is just to join the peripheral part 30 by other methods, such as using an adhesive agent.

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

  A partition sealing portion 28 that extends in the horizontal direction in FIG. 1 and that can communicate is formed at a substantially central portion in the vertical direction of the container body 12. By the partition sealing portion 28, the internal space of the container body 12 is partitioned into an upper space (hereinafter, “first storage portion 24”) and a lower space (hereinafter, “second storage portion 26”). As a result, two or more kinds of drugs that are not suitable to be mixed or dissolved in advance can be stored in the container body 12. For example, various chemicals that need to be isolated in order to cause browning due to the Maillard reaction can be enclosed. Specifically, one of the storage units 24 or 26 contains an amino acid solution, and the other storage unit 26 Alternatively, a solution containing glucose can be stored in 24. Further, not only a liquid drug but also a solid or powder drug may be stored.

  The partition sealing portion 28 is formed by heat-sealing 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 medicine discharge unit 14 is connected to the end of the container body 12 on the second storage unit 26 side. The medicine discharge part 14 is composed of a medicine discharge pipe 16 having a passage through which the medicine passes, and a rubber plug 18 that closes the medicine discharge pipe 16. Here, when the medical multi-chamber container 10 is used (after the partition sealing portion 28 is opened), the medicine in the container body 12 is administered to the patient by inserting the piercing needle into the rubber plug 18. It becomes possible.

  As shown in FIGS. 1 and 2, the covering member 22 covers the entire container body 12 and the medicine discharge part 14. In the present embodiment, the covering member 22 is composed of a single-layer or multi-layer cover film, and is folded into two to be used as a front-side first cover film 22a and a back-side second cover film 22b. ing. These covering films 22a and 22b have a rectangular shape larger than the container body 12 and have substantially the same dimensions. The container main body 12 and the medicine discharge part 14 are sealed by sandwiching the container main body 12 and the drug discharge part 14 between these coating films 22a and 22b and joining them all around the peripheral part 32 of the cover films 22a and 22b. Has been.

  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 medicine discharge section 14 by vacuum packaging that sucks air between the covering member 22 and the container main body 12. ing. The covering member 22 is joined to substantially the entire container body 12 (the outer surfaces of the first storage portion 24, the partition sealing portion 28, and the second storage portion 26). The bonding strength at each part will be described later.

  The bonding may be performed using an adhesive or the like, but is preferably performed 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 on the outer surfaces of the films 12a and 12b constituting the container body 12 and the resin used on the inner surfaces of the covering films 22a and 22b constituting the covering member 22 may be resins having a relatively low melting point. preferable. Thereby, the outer surface of the films 12a and 12b constituting the container main body 12 and the covering constituting the covering member 22 are applied to the medical multi-chamber container 10 by 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 constituting the inner surface of the covering member 22 and the heat contained in the outer surfaces of the films 12a and 12b constituting the container body 12 are used. It is also preferred that the plastic resin is common to 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 usually applied in the final stage of the manufacturing process of the medical multi-chamber container 10 to be 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 made higher than that of the partition sealing portion 28 in which the bonding strength is lowered by a mixture of polypropylene and polyethylene. Can do.

  In the medical multi-chamber container 10 of the present embodiment, since the medicine discharge portion 14 is also covered with the covering member 22, the upper surface of the rubber plug 18 of the medicine discharge portion 14 is covered from the viewpoint of hygiene. The peel seal normally used in the case is not necessary. In addition, since the medicine discharge portion 14 is covered with the covering member 22 before use, it is possible to prevent the use of the plurality of storage portions 24 and 26 before opening.

  In addition, it is preferable that the films 22a and 22b of the covering member 22 have light shielding properties, gas barrier properties, and water vapor barrier properties. Further, as understood from FIG. 2, depending on the shape of the container main body 12 and the drug discharge portion 14 and the properties of the films 22 a and 22 b of the cover member 22, the cover member 22 and the container main body 12 and the drug discharge portion 14 A space may be formed between them. In such a case, an oxygen absorbent or a moisture absorbent may be enclosed in this space. Accordingly, even when the drug in the container body 12 is a component that deteriorates due to oxygen or moisture, deterioration can be suppressed.

  Next, the usage method of the medical multi-chamber container of this embodiment is demonstrated.

  FIG. 3 is a schematic cross-sectional view showing the operation when the covering member 22 is peeled from the container body 12. As shown in FIG. 3, when the use of the medical multi-chamber container 10 is started, the covering member 22 is moved from the medicine discharge section 14 side to the first storage section 24 side not adjacent to the medicine discharge section 14. The covering films 22a and 22b on both sides are peeled off. In addition, as shown in FIG. 1, FIG. 2, the knob part 34 is formed in the peripheral part 32 of the coating film (front side, 22a) of the coating | coated member 22. As shown in FIG. For this reason, it becomes easy to peel the covering member 22 by gripping the end portion 36 and the knob portion 34 of the covering film (back side, 22b).

  Here, the bonding strength between the covering member 22 and the container body 12 will be described in detail. The first covering film 22a and the second covering film 22b of the covering member 22 are formed on the first film 12a and the second film 12b on the partition sealing portion 28 by the first sealing portion 28. 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 pulled away from the medicine discharge portion 14 and the container body 12 to start using the multi-chamber container 10, the partition sealing portion 28 is also caused by the tensile forces F and F. The container is opened and the two storage portions 24 and 26 are reliably opened. For this reason, it becomes possible to administer to the patient after the medicines individually stored in the two storage portions 24 and 26 are reliably mixed. The first covering film 22a and the second covering 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. Bonding with bonding strength is preferable from the viewpoint of more reliably opening the partition sealing portion 28.

  Moreover, the 1st coating film 22a and the 2nd coating film 22b of the coating | coated member 22 are joined to the 1st film 12a and the 2nd film 12b on the 2nd accommodating part 26 so that peeling is possible, and peeling If possible, the bonding strength may be any strength. However, the first covering film 22a and the second covering 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 film 12a on the second storage portion 26. And it is preferable that it is joined to the 2nd film 12b so that peeling is possible. Thereby, since the opening of the partition sealing portion 28 is started by the operation of peeling the covering member 22 from the second storage portion 26, the opening can be further reliably performed. In addition, the 1st coating film 22a and the 2nd coating film 22b are higher than the joint strength of the partition sealing part 28 to the 1st film 12a and the 2nd film 12b on the 2nd accommodating part 26. It is more preferable that they are bonded with bonding strength.

  Further, the bonding strength between the first coating film 22a and the second coating film 22b of the coating member 22 and the first film 12a and the second film 12b on the first storage portion 24 is determined by the partition sealing. From the viewpoint of opening the portion 28, there is no particular limitation. However, 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 from preventing the container body 12 from being peeled off from the covering member 22 due to a load such as a medicine. And the films 12a and 12b on the first storage unit 24 are preferably bonded with a bonding strength that does not peel off due to a load such as a drug, and may be bonded so that they cannot be peeled off.

  As shown in FIG. 3, the first covering film 22 a and the second covering film 22 b on both sides of the covering member 22 may not be peeled from the container body 12. In a medical institution, treatment of medical waste is strict and thorough separation is performed. In the case of the multi-chamber container 10 of the present embodiment, the container body 12 and the covering member 22 are integrated. Therefore, it can be disposed of in a convenient manner, and the convenience of separation processing is reduced.

  FIG. 4 is a schematic cross-sectional view showing a state in use of the medical multi-chamber container. As shown in FIG. 4, the first covering film 22 a and the second covering film 22 b of the covering member 22 peeled from the medicine discharge section 14 side are joined to the outer surface side of the container body 12 when the container body 12 is covered. The inner surface is inverted by turning back around the partition sealing portion 28 and becomes the outer surface. In addition, the outer surface of the container body 12 when covered is similarly reversed to be reversed to become the inner surface, and the outer surfaces of the first covering film 22a and the second covering film 22b covering the first storage portion 24 side. And overlap.

  As shown in FIG. 4, the first coating film 22 a and the second coating film 22 b are separated from the first film 12 a and the second film 12 b on the drug discharge unit 14 and the second storage unit 26 of the container body 12. In the state of peeling and folding back to the opposite side with the partition sealing portion 28 as the center, a hook insertion hole 38 is formed on the outer side of the end portion of the container body 12 on the side opposite to the medicine discharge 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 covering film 22 a and the second covering film 22 b of the covering member 22 on the side of the medicine discharge section 14. Thereby, the medical multi-chamber container 10 can be suspended from the hook 40 of a 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 peeling of the covering member 22 until it is hung on the drip stand and starts to be used. be able to. In the case of a conventional multi-chamber container, for example, if the container is left during the opening operation of the partition sealing portion, the partition sealing portion is unsealed, resulting in mixing of the medicines and changes over time. According to the chamber container, use can be started by a series of operations, so that it is easy to prevent the chamber container from being left during 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 covering film 22 a and the second covering film 22 b of the covering member 22 are the first film 12 a on the partition sealing portion 28 and the second storage portion 26 of the container body 12. And only the first film 12a and the second film 12b on the partition sealing portion 28 may be bonded. For example, when the covering member 22 is joined to the container body 12 that has been subjected to high-pressure steam sterilization, the amount of adhesive used can be reduced when the joint portion between the two is small. In addition, in the medical multi-chamber container 10b of such a modification, the space between the covering member 22 and the container main body 12 or the medicine discharge part 14 becomes wider than the medical multi-chamber container 10 shown in FIG. Because of this tendency, it is preferable to enclose the oxygen absorbent or the water absorbent A in order to suppress the deterioration of the medicine in the container body 12. Further, from the viewpoint of preventing the drop when the medical multi-chamber container 10b of FIG. 5 is hung on the drip stand, the first covering film 22a and the second covering film 22b of the covering member 22 and the partition sealing portion 28 are also provided. The joint portion between the first film 12a and the second film 12b is preferably joined with a joining strength that does not peel off due to a load such as a drug, and may be joined so as not to peel off.

  FIG. 6 is a schematic cross-sectional view showing a modification of the medical multi-chamber container 10c. As shown in FIG. 6, the covering member 22 covers up to the second storage portion 26 and the partition sealing portion 28, and does not cover the first storage portion 24. Thus, from the viewpoint of resource saving, the covering member 22 may be provided only on a part of the container body 12. Further, when storing a drug that easily deteriorates due to oxygen or moisture, a material that suppresses permeation of oxygen or moisture is used as the covering member 22, and the drug is supplied to the second storage portion 26 covered with the covering member 22. It may be stored. The medical multi-chamber container 10c is similar to the medical multi-chamber container 10b in that the first covering film 22a and the second covering film 22b of the covering member 22 are prevented from being dropped when hung on the drip stand. In addition, it is preferable that the joining portions of the first film 12a and the second film 12b on the partition sealing portion 28 are joined with a joining strength that does not peel off due to a load such as a drug, and are joined so as not to be peeled off. It may be.

  FIG. 7 is a schematic cross-sectional view showing a modification of the medical multi-chamber container. As shown in FIG. 7, the container body 12 and the medicine discharge part 14 may be covered with blister packaging. For example, the container body 12 is disposed on the second covering film 22b of the covering member 22 so that the second film 12b of the container body 12 is in contact therewith. Subsequently, the first covering film 22 a of the covering member 22 is disposed on the first film 12 a of the container main body 1 to cover the container main body 12 and the medicine discharge unit 14. Next, the container main body 12 and the chemical | medical agent discharge part 14 can be sealed by joining the peripheral part 32 of the 1st coating film 22a and the 2nd coating film 22b. Furthermore, the container body 12 and the covering member 22 can be brought into close contact with each other by sucking the air between the covering member 22 and the container body 12 and vacuum-packaging it.

  Also in the medical multi-chamber container 10d by the blister packaging of the present embodiment, since the thermoplastic resin such as polyethylene or polypropylene can be used as the covering member 22, the outer surface of the container body 12 and the covering member 22 are heated by heat during high-pressure steam sterilization. Can be joined to the inner surface. The first covering film 22a and the second covering film 22b of the covering member 22 are formed on the first film 12a and the second film 12b on the partition sealing portion 28 by the first sealing portion 28. The film 12a and the second film 12b are bonded with a bonding strength equal to or higher than the bonding strength. The medical multi-chamber container 10d by the blister packaging of this embodiment is excellent in impact resistance. For this reason, when transporting a normal medical multi-chamber container, there is a case where a double back method is adopted in which the partition sealing portion is folded in two so as not to open due to an impact, but the medical multi-chamber container 10d of this embodiment is used. According to this, it is not necessary to fold it into two at the time of transportation, and it becomes possible to simplify the work at the time of a packaging process. The first covering film 22a and the second covering 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. Bonding with bonding strength is preferable from the viewpoint of more reliably opening the partition sealing portion 28.

  FIG. 8 is a schematic cross-sectional view showing a modification of the medical multi-chamber container. The medical multi-chamber container 10e shown in FIG. 8 has the medical cover shown in FIG. 7 in that the second covering film 22b of the covering member 22 is not joined to the second film 12b on the partition sealing portion. The shape is different from the multi-chamber container 10d. Here, the first covering film 22a of the covering member 22 is formed on the first film 12a on the partition sealing portion 28 by the first film 12a and the second film 12b of the partition sealing portion 28. The second covering film 22b of the covering member 22 is bonded to the second film 12b on the second storage portion 26 and the first storage portion 24 for partitioning with a bonding strength higher than the bonding strength. The first film 12a and the second film 12b of the sealing portion 28 are bonded with a bonding strength equal to or higher than the bonding strength. According to the medical multi-chamber container 10e, the partition sealing portion 28 is easily opened when the first covering film 22a and the second covering film 22b of the covering member 22 are peeled off.
