[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention provides a multi-chamber medical container, more specifically, a plurality of chambers for individually storing various unstable drugs (solutions, powders, or solids) that may change with time when mixed at the same time. The present invention relates to a medical double-chamber container capable of mixing medicine contained in each room in an aseptic state and without generating foreign matter by peeling and opening the weak seal portion.

[0002]

[Prior art]

 Some drugs that are administered to patients by intravenous injection are unstable drugs that, when pre-combined, cause undesired changes over time. For example, if an amino acid infusion and a glucose infusion are mixed and stored, the mixture turns brown by the so-called Maillard reaction. In addition, if the fat emulsion and the electrolyte solution are blended and stored, the fat content will coagulate, and if the phosphoric acid-containing solution and the calcium-containing solution are blended, calcium phosphate will precipitate, causing undesirable changes. Wake up.

[0003] A multi-chamber medical container for individually storing components before mixing is often used for such a drug. This multi-chamber medical container includes a plurality of storage sections for individually storing medicines, and a partition weak seal section that separates the storage sections and can be peeled off by applying pressure from the outside.

FIG. 4 is a plan view showing an example of such a conventional multi-chamber medical container, and FIG. 5 is a sectional view taken along line XX of FIG.

Various medicines a and b, which are not desired to be mixed or dissolved beforehand, are housed in the respective storage sections 10 and 11 of the medical multi-chamber container, and these medicines a and b are used for partitioning. It is safely and securely stored until it is used while being isolated by the seal portion 20. When the storage unit 10 or 11 is pressed during use, the weak seal portion 20 for partitioning peels off, and the inside of both storage units 10 and 11 is in a communicating state, so that the two medicines a and b can be mixed or dissolved quickly. it can.

Further, the medical double-chamber container has a hanging hole 30 at one end and a medicine outlet 32 having a rubber stopper at the other end. When administering the mixed drug to a patient, the container is hung on a support or the like with the hanging hole 30 and then a puncture needle is inserted into a rubber stopper provided at one end of the container. Administer to the patient through a needle.

However, such a medical double-chamber container often stores a liquid agent in the storage portion 11 on the side of the medicine outlet 32, so that the partitioning weak seal portion 20 is not peeled off, but instead a rubber stopper is used. There is a possibility that the puncture needle is inserted and the liquid medicine is taken out from the medicine outlet 32.

It is intended to provide a multi-chamber medical container characterized by the following.

[0010]

[Embodiment of the invention]

 Hereinafter, an embodiment of the medical multi-chamber container according to the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a medical multi-chamber container according to the present embodiment, and FIG. 2 is a cross-sectional view of a weak seal portion.

As shown in FIG. 1, a multi-chamber medical container 1 according to the present embodiment has a container body 3 having a peripheral portion 2 fused and formed in a rectangular shape, and a rubber connected to the container body 3. And a medicine outlet 32 having a stopper. The container main body 3 has a first storage section 10 and a second storage section 11 arranged side by side in the longitudinal direction. The two storage sections 10 and 11 are separated by a weak sealing section 20 which can be opened. I have. The above-mentioned medicine outlet 32 is connected to the second storage part 11, and the medicine outlet 32 and the second storage part 11 are separated by the dischargeable weak seal 21 that can be opened. In addition, in the storage sections 10 and 11, various medicines a and b that are not desirable to be mixed or dissolved in advance are stored, respectively.

The medical multi-chamber container 1 can be a bag-shaped container formed by heat-sealing or bonding the peripheral portions 2 of two flat-layer or multi-layer films. As the material of the film, various resins such as a thermoplastic resin such as polyethylene, polypropylene and polystyrene can be adopted.

The partitioning weak seal portion 20 and the discharge weak seal portion 21 are configured as follows. As shown in FIG. 2 (a), in this multi-chamber container 1, one of the film surfaces 3a on both sides of the container body 3 is provided with a ridge 35 having a circular cross section, and the other surface 3b is formed with a U-shaped cross section. Are provided. The weak seal portions 20 and 21 are configured by fitting them removably by elastic deformation. On the other hand, when a predetermined pressure acts on the storage sections 10 and 11, the convex ridges 35 and the concave ridges 36 are detached, and the weak seal portions 20 and 21 are opened.

The pressure required to open the discharge weak seal portion 21 is higher than the pressure required to open the partition weak seal portion 20. At this time, the difference in the opening strength required for opening the weak seal portion 21 for discharge and the weak seal portion 20 for partition (difference in the pressing force of the multi-chamber medical container necessary for opening) is, for example, about 5 kg to about 5 kg. It is preferably 10 kg. Various methods can be employed to provide such a difference in opening strength. For example, when the thickness of the concave streak portion 36 is increased, elastic deformation is difficult to be performed. The opening strength of the seal portion 21 can be increased. Also, the opening strength can be increased by providing minute projections and depressions on the fitting surface of the convex ridge 35 or the concave ridge 36 and increasing the frictional force between them. Further, the difference in the opening strength can also be provided by forming the partition weak seal portion 20 and the discharge weak seal portion 21 from different materials.

The discharge weak seal portion 21 can be formed in parallel with the partition weak seal portion 20 as shown in FIG. 1, or for example, around the medicine discharge port 32 as shown in FIG. It can be formed in an arc shape.

Next, a method of using the medical double-chamber container configured as described above will be described. In order to administer the medicine in the container to the patient, first, the first storage unit 10 is pressed by hand or the like to increase the pressure in the storage unit 10. As a result, the partition weak seal portion 20 is opened, the first and second storage portions 10 and 11 communicate with each other, and the medicines a and b in each of the storage portions 10 and 11 are mixed. Next, the whole of the first and second storage sections 10 and 11 is pressed to increase the pressure of the whole of the connected storage sections 10 and 11, and the weak discharge seal section 21 is opened. Subsequently, when the puncture needle is inserted into the rubber stopper, the mixed medicine in the container 1 is administered to the patient through the outlet 32 through the conduit.

As described above, according to the present embodiment, the discharge weak seal portion 21 is provided, and the second storage portion 11 and the discharge port 32 are not in direct communication with each other. Even if the puncture needle is inserted into the outlet 32 by mistake before opening the container, the medicine b before mixing in the second storage portion 11 is prevented from being discharged from the outlet 32. . In this case, since the medicine is not discharged from the outlet 32 even if the puncture needle is inserted, the user must confirm that the discharge weak seal portion 21 and the partition weak seal portion 20 have not been opened. Can be recognized. Therefore, by providing the discharge weak seal portion 21, it is possible to evoke a proper use method, that is, to use the correct weak seal portion 21 after opening the partition weak seal portion 20 in the correct order. Can be.

Further, as described above, since the weak seal portions 20 and 21 are formed by fitting the convex ridges 35 and the concave ridges 36, manufacture of the container is facilitated. For example, if both weak seals are formed by heat-sealing the film surface, in order to provide a difference in the opening strength, the weak seals must be fused by adjusting the welding time, welding pressure, etc. Production was not always easy. On the other hand, when configured as described above, the seal portion can be formed only by fitting the convex ridge portion 35 and the concave ridge portion 36, and the container can be easily manufactured. In addition, in the case of fusion, it may be difficult to sufficiently fuse the film surface if powder or water droplets of the chemical are scattered on the fusion surface. Even in this case, the convex ridge 35 and the concave ridge 36 can be securely fitted to each other, and sufficient sealing strength can be obtained.

One of the medicines stored in each of the storage sections 10 and 11 may be a liquid medicine so that the pressure in the storage sections 10 and 11 can be increased, but the second storage section 11 may be used. When a liquid medicine is stored in the container, there are the following advantages. That is, since the pressure required to open the weak discharge seal portion 21 is higher than the pressure required to open the weak seal portion 20 for partitioning, when the second storage portion 11 is pressed, the weak pressure for partition After the seal portion 20 is opened, the discharge weak seal portion 21 is opened. Therefore, the mixing or dissolution of the medicines a and b in the two storage sections 10 and 11 can be completed before the medicine is discharged by opening the weak seal portion 21 for discharge. Therefore, it is possible to ensure that the medicine discharged from the medicine outlet 32 is after mixing.

The present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention. For example, the shapes of the convex ridges 35 and the concave ridges 36 are not limited to those described above, and may be configured so that the convex ridges 35 and the concave ridges 36 are detachably fitted. . For example, as shown in FIG. 2B, the convex ridge 35 may be formed in a hook-shaped cross section, and the concave ridge 36 may be formed so as to include a locking piece 36a capable of locking the convex ridge 35. As shown in FIG. 2, the convex ridges 35 and the concave ridges 36 may be formed by attaching separately prepared members to the film surfaces 3a, 3b, or integrally with the film surfaces 3a, 3b. It can also be formed.

In the medical double-chamber container according to the above embodiment, the two weak seal portions are both formed by the concave-convex fitting. However, this is not always necessary, and any one of them may be used if necessary. It is also possible to form the weak seal portion by uneven fitting and the other by heat fusion of the film surface.

In the above-described embodiment, the opening strength of the discharge weak seal portion 21 is set to be greater than the opening strength of the partitioning weak seal portion 20, but they may be set to be equal. it can.

Further, the medical double-chamber container of the above embodiment is configured to be able to mix two types of drugs, but is not limited to this, and is provided with two or more storage units. You may.

[0024]

[Effect of the invention]

 As is clear from the above description, according to the medical double-chamber container of the present invention, the storage section and the medicine discharge port are separated by the weak discharge seal section. Even if the medicine is accidentally taken out from the medicine discharge port before opening, the medicine before mixing in the storage section is prevented from being discharged from the discharge port.

Also, since the convex and concave portions provided on the film surface are removably fitted by elastic deformation to form a weak seal portion, the container can be manufactured easily and more reliably. be able to. For example, if the weak seal portion is formed by heat fusion of the film surface, it may be difficult to sufficiently fuse the film surface if a chemical or the like scatters on the fusion surface. On the other hand, if the weak seal portion is formed by fitting the concave and convex portions as described above, a reliable seal strength can be obtained even if the medicine is scattered in the seal portion.
