[0005] In the storage sections 10 and 11 of the medical multi-chamber container, various medicines a and b, which are undesirable if they are mixed or dissolved in advance, are housed. 20 and stored safely and securely in isolation until use. When used, pressing the storage portion 10 or 11 peels off the weak seal portion 20 for partitioning,
The insides of both storage sections 10 and 11 are in communication with each other, and both medicines a and b
Can be quickly mixed or dissolved.

Further, the medical double-chamber container has a hanging hole 30 at one end.
And a chemical solution 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 column 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 to inject the distal end of the catheter. Administer to the patient through a needle.

However, such a multi-chamber medical container often stores a liquid agent in the storage portion 11 on the side of the chemical liquid outlet 32, and does not peel off the weak seal portion 20 for partitioning.
There is a possibility that a puncture needle is inserted into the rubber stopper and the liquid agent is taken out from the chemical liquid outlet 32.

[0008]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a medical double-chamber container according to the present invention. In the following description, the same reference numerals are given to the same or similar parts throughout a plurality of embodiments.

(First Embodiment) A first embodiment of a multi-chamber medical container according to the present invention will be described in detail. FIG. 1 is a perspective view of a first embodiment of a medical multi-chamber container according to the present invention, and FIG. 2 is a plan view of the medical multi-chamber container of FIG.

As shown in FIG. 1, a multi-chamber medical container 1 comprises:
A container body 3 having a peripheral portion 2 fused and formed in a rectangular shape;
A first storage unit 10 and a second storage unit 11 arranged side by side in the longitudinal direction of the container body 3 and two storage units 10 and 11
Partitioning weak seal portion 20 for partitioning a medicine, and a medicine outlet 32 connected to the second storage portion 11 and having a rubber stopper 31
And a weak peelable discharge seal portion 21 that partitions between the second storage section 11 and the medicine discharge port 32. In addition, the respective storage portions 10 and 11 store various medicines a and b, respectively, which are undesirable if they are mixed or dissolved in advance.

The multi-chamber medical container 1 can be a bag-shaped container formed by heat-sealing or bonding the peripheral portions 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 weak seal portion 20 for partition and the weak seal portion 21 for discharge are formed to be openable in various modes.
For example, both sides of the film forming the medical multi-chamber container 1 may be bonded by heat fusion to form the partition weak seal portion 20 and the discharge weak seal portion 21. The weak discharge seal portion 21 can be formed in parallel with the weak partition seal portion 20 as shown in FIG. 1, or can be formed in an arc around the medicine discharge port 32 as shown in FIG. 3, for example. It can also be formed.

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. Thereby, when the medicines a and b are mixed by pressing the respective storage portions, the weak seal portion 21 for partition is opened before the weak seal portion 20 for discharge, so that only the weak seal portion 20 for discharge is opened. Can be prevented. Further, it is possible to reliably prevent an accident in which a drug is administered to a patient without being mixed by mistake. Preferably, the difference in the opening strength (weight when the medical double-chamber container is pressed) required to peel off the weak seal portion 21 for discharge and the weak seal portion 20 for partition is about 5 kg to about 10 kg.

As described above, according to the present embodiment, by adjusting the pressure required to separate the weak seal portion 21 for discharge and the weak seal portion 20 for partition, each of the storage portions 1 is adjusted.
When the medicines a and b stored in 0 and 11 are mixed, the weak seal portion 21 for discharge can be peeled off after the weak seal portion 20 for partitioning has been peeled off.

That is, the mixing or dissolving of the medicines a and b stored in each storage section has been completed before the weak seal portion 21 for discharge is peeled off and the medicine can be administered to the patient. Therefore, it is possible to reliably discharge the mixed medicine from the medicine outlet 32.

Various methods can be used to adjust the pressure required for separating the weak seal portion 21 for discharge and the weak seal portion 20 for partitioning. For example, by forming the container body from polyethylene (PE), the welding strength of the discharge weak seal portion 21 is smaller than the welding strength of the peripheral portion 2 of the container body, and the partitioning weak seal portion 21 is fused. It can be larger than the strength.

In order to provide such a difference in the fusion strength, for example, the heat fusion time of the discharge weak seal portion 21 is shorter than the heat fusion time of the peripheral portion 2 of the container body, and the partition weak seal portion is formed. Longer than the heat-sealing time. Alternatively, the fusing strength of the weak seal portion for discharge is adjusted to be lower than the fusing pressure of the peripheral portion 2 of the container body and higher than the fusing pressure of the weak sealing portion for partitioning. Is possible.

By adjusting the fusion strength in each part of the multi-chamber container in this manner, it is possible to prevent only the discharge seal portion 21 from being opened earlier. This ensures that the mixed medicine is discharged from the medicine outlet 32. In addition, as described later, each of the seal portions 2
By adjusting the widths of 0 and 21, the partitioning weak seal portion 20 can be opened first.

Since the peripheral portion 2 of the container body 3 has a higher fusion strength than the weak seal portion 21 for discharging, the peripheral portion 2 of the container body 3 remains open even after the weak seal portion 21 for discharging is opened. Opening is prevented, and leakage of the chemical solution from the storage sections 10 and 11 is prevented.

Alternatively, the pressure required for peeling the weak seal portion 21 for discharge may be equal to the pressure required for peeling the weak seal portion 20 for partition. As a result, the partition weak seal portion 20 and the discharge weak seal portion 2
1 is opened almost at the same time and only the weak seal portion 21 for discharge is not opened, so that the medicine in each storage section can be surely mixed with the patient before administration.

Further, as described above, the weak sealing portion 20
And the pressure required for opening the discharge weak seal portion 21 are made substantially equal, so that the partition weak seal portion 20 and the discharge weak seal portion 21 are fused and formed under the same conditions. Therefore, the manufacture of the multi-chamber container 1 is easy. In particular, in a multi-chamber container in which the powder agent is stored in the second storage portion 11 on the side of the medicine outlet 32 and the chemical solution is stored in the first storage portion 10, the first storage portion 10 farther from the drug solution outlet 32 is provided. Is pressed, so that the partitioning weak seal portion 20 is opened, the chemical solution and the powder agent are always mixed, and only the discharge weak seal portion 21 is opened before the partitioning weak seal portion 20 is opened. Can be prevented beforehand.

Further, the shape of the partition weak seal portion may be, for example, a curved shape other than the linear shape described above. As shown in FIG. 4, in this example, the discharge weak seal portion 21 is formed in an arc shape so as to surround the medicine discharge port 32, and the partition weak seal portion 20 is provided outside the discharge weak seal portion 21. It is formed in an arc shape that is almost concentric with
The first storage part 10 is formed in the upper part in the container main body 3, and the second storage part 21 is formed in the lower part. By configuring each of the seal portions 20 and 21 in this manner, the same effect as described above can be obtained.

In this embodiment, the two storage units 10 and 11
Are arranged side by side in the longitudinal direction of the container body 3, but may be arranged side by side in the direction crossing the longitudinal direction, for example, as shown in FIG. As shown in the figure, in the medical multi-chamber container 1, an inverted V-shaped weak discharge sealing portion 21 is provided so as to surround the medicine discharge port 32. Then, from the top of the weak sealing portion 21 for discharge to the peripheral portion 2 opposed thereto, a weak sealing portion 20 for partition formed narrower than the weak sealing portion 21 for discharging extends in the longitudinal direction of the container body 3, A first storage section 10 is formed on the left side of the main body 3 and a second storage section 11 is formed on the right side. Further, as shown in the figure, a guide seal portion 22 wider than the discharge weak seal portion 21 is formed from the top of the discharge weak seal portion 21 toward the peripheral portion 2 on the side of the container body 3. desirable. Such a guide seal portion 22
Is provided, all of the medicine stored in the first storage unit 10 can flow into the second storage unit 11 when the weak partition seal portion 20 is peeled off.

In this multi-chamber medical container 1, the peel strength of the weak discharge seal 21 is increased by making the width of the weak seal 21 for discharge wider than the width of the weak seal 20 for partition. Weak seal part 20 for discharge is weak seal part 21 for discharge.
It peels off earlier. Therefore, it is possible to provide a difference in the peel strength between the weak seal portions 20 and 21 while keeping the fusion time or the fusion pressure in the weak seal portions 20 and 21 the same, thereby shortening the manufacturing time of the container 1. And reduction of manufacturing costs. Further, in order to provide such strength of the peel strength of the seal portion, not only the width of the seal portion is adjusted but also various methods such as the adjustment of the fusion time described above can be adopted.

Although the width of the guide seal portion 22 is made larger than the width of the discharge weak seal portion 21 so as not to be easily peeled as described above, the peeling of the guide seal portion 22 is ensured. For example, as shown in FIG.
A portion surrounded by the guide seal portion 22 and the peripheral edge portion 2 may be fused to integrate the guide seal portion 22 with the peripheral edge portion 2.

(Second Embodiment) A second embodiment of the medical double-chamber container according to the present invention will be described with reference to FIGS. FIG. 7 is a plan view of the medical multi-chamber container according to the second embodiment. FIG. 8A is a plan view for explaining the operation of the protruding portion, and FIG. FIG. 3 is a sectional view taken along line AA.

The main difference between the second embodiment and the first embodiment described above is that the second embodiment is provided with a protruding portion for relatively reducing the pressure required for peeling the weak seal portion for partitioning. It is a point.

As shown in FIG. 7, this medical multi-chamber container 1
Then, the partition weak seal portion 20 and the discharge weak seal portion 21
Are formed with the same width, and are fused at the same fusion time and fusion pressure. Further, the weak seal portion 20 for partitioning has a protruding portion 20a formed in the middle thereof in a V-shape.
As shown below, the protruding portion 20a allows the partitioning weak seal portion 20 to be discharged by the discharge weak seal portion 21.
It can be opened earlier.

As shown in FIG. 8A, the storage units 10, 1
When the pressure in 1 increases, pressure acts on the weak seal portion 20 for partitioning in the direction of the arrow in the figure. At this time, since the pressure acts on the seal portion 20 vertically and equally,
The total pressure acting on the area near the top B of the protrusion 20a is:
The height is higher than other areas of the seal portion 20. Thus,
As shown in FIG. 8B, this pressure acts in a direction for separating the film constituting the container main body 3, and
When the pressure in the inside 11 increases, the weak sealing portion 20
Starts peeling from the top B of the protrusion 20a. Thereby, the peeling proceeds rapidly under the action of the pressure, and the first storage unit 10 and the second storage unit 11 communicate with each other to mix the medicines a and b. Subsequently, when the container body 3 is further pressed,
The discharge weak seal portion 21 is peeled off, and the mixed medicine can be discharged from the medicine discharge port 32.

As described above, in the present embodiment, since the V-shaped projection 20a is provided on the discharge weak seal portion 20, the partition weak seal portion 20 and the discharge weak seal portion 21 have the same width. Even when they are fused at the same fusion temperature and fusion pressure, when the pressure is applied to the storage portions 10 and 11, the protruding portion 20a starts peeling the earliest, and Prior to the weak seal portion 21, the partition weak seal portion 20 can be opened. As a result, after the medicines a and b stored in the storage sections 10 and 11 are surely mixed, the weak seal 21 for discharge can be opened, and the mixed medicine is discharged from the medicine discharge port 32. Can be done.

In this embodiment, only the shape of the partitioning weak seal portion 20 is changed, and the weak seal portion 2 is changed.
Since it is possible to adjust the pressure required for peeling the weak seals 0 and 21, there is no need to adjust the welding time and the like of the weak seals 20 and 21, and the weak seals 20 and 21 are fused under the same conditions. can do. As a result, it is possible to reduce the manufacturing time and the manufacturing cost of the container 1. In particular, since the partition weak seal portion 10 and the discharge weak seal portion 11 are formed with the same width, unevenness of fusion can be eliminated, and the entire weak seal portions 10 and 11 can be uniformly fused. You can wear it.

In this embodiment, the storage units 10 and 11
Are formed in the medical multi-compartment container 1 in which the container portions 3 are arranged in the longitudinal direction of the container body 3. The projecting portion 20 a, for example, as shown in FIG.
It is needless to say that the present invention can be applied to a case in which the elements are arranged in a direction crossing the longitudinal direction of the elements. Further, the number of the protruding portions 20a is not limited to one, and a plurality of protruding portions 20a may be provided as shown in FIG.

The shape of the protruding portion is not limited to the V-shape, but may be any shape having a protruding portion on which pressure is easily concentrated.

(Third Embodiment) A third embodiment of the medical multi-chamber container according to the present invention will be described with reference to FIG. FIG. 10 is a plan view of a medical multi-chamber container according to the third embodiment.

The medical multi-chamber container according to this embodiment is characterized in that the container main body is provided with a bag-shaped inner container in which at least one of the medicines to be mixed is stored without providing a weak seal portion for partitioning. , Is different from the first embodiment.

As shown in FIG. 10, the medical multi-chamber container 1 is provided with an arc-shaped weak discharge seal 21 surrounding the medicine discharge port 32, and the seal 21 allows the container main body 4 as an outer container to be formed. Storage section 1 surrounded by peripheral portion 2
2 and a medicine outlet 32 are partitioned. The medicine accommodating section 12 directly accommodates one medicine a of the two kinds of medicines to be mixed, and has a bag-shaped inner container 13.
Is stored. The inner container 13 is provided with a weak sealing portion 23 for sealing formed by laminating two films and fusing the peripheral portions thereof, and the other medicine b is accommodated therein.
The sealing weak seal portion 23 is fused with a lower fusion strength than the discharge weak seal portion 21, and is configured to be peeled off at a low pressure.

When mixing the medicine, the container body 4
Is pressed, the pressure also acts on the inner container 13 housed therein, and the pressure in the inner container 13 increases. As a result, the weak sealing portion 23 for sealing peels off before the weak sealing portion 21 for discharge, and the medicine b stored in the inner container 13 is diffused into the medicine storing section 12 of the container body 4 and the medicine b mixed with a. Thereafter, when the puncture needle is inserted into the medicine outlet 32, the mixed medicine can be discharged.

As described above, according to the present embodiment, the medicine storage section 12 and the medicine discharge port 32 are separated by the weak discharge seal section 22, so that the medicine discharge port is erroneously prepared before mixing the medicine. Even when the opening 32 is opened, it is possible to prevent the medicine before mixing from flowing out. Further, since the pressure required for peeling the weak sealing portion 21 for discharging is higher than that of the weak sealing portion 23 for sealing, when the container body 4 is pressed, the sealing is performed prior to the weak sealing portion 21 for discharging. The stop weak seal portion 23 can be peeled off. As a result, when the weak sealing portion for discharge 21 is peeled off, the weak sealing portion for sealing 23 is already peeled and the medicine is mixed, so that only the mixed medicine is discharged from the medicine outlet 32. can do. Further, the first or second
Unlike the embodiment, there is no need to provide the weak sealing portion 20 for the partition, so that the manufacturing process can be simplified.

In this embodiment, the peripheral portion of the inner container 13 is the weak sealing portion 23 for sealing. However, the present invention is not limited to this. For example, only a part of the inner container 13 is provided with an opening, A weak sealing portion for sealing may be provided so as to seal the opening.

(Fourth Embodiment) A fourth embodiment of the multi-chamber medical container according to the present invention will be described with reference to FIG. FIG. 11 is a plan view of a medical multi-chamber container according to the fourth embodiment.

The medical multi-chamber container according to the present embodiment does not have the weak seal portion for discharge and the weak seal portion for the partition, but has an inner container containing the medicine to be mixed inside the container body. This is different from the first embodiment.

As shown in FIG. 11, this multi-chamber medical container 1 has a bag-like shape in which medicines a and b to be mixed are stored in a storage portion 14 surrounded by a peripheral portion 2 of a container body 4 as an outer container. Are stored. The inner containers 15 and 16 each include a weak sealing portion 23 for sealing formed by laminating two films and fusing the peripheral portions thereof, and accommodate the medicines a and b therein. Each inner container 15, 16 is formed in a rectangular shape, and each inner container 15, 1 is formed.
The weak sealing portion 23 for sealing is fused with almost the same strength.

When mixing the medicine, the container body 4
Is pressed, the inner container 15,
The pressing force acts on the inner container 16, and the pressure in each of the inner containers 15 and 16 increases. When the container body 4 is pressed in this manner, the weak sealing portions 23 for peeling off are almost simultaneously separated, and the medicines a and b stored in the inner containers 15 and 16 are stored in the storage portion 14 of the container body 4. It diffuses and the two drugs a and b are mixed.
Subsequently, when a puncture needle is inserted into the medicine outlet 32,
The mixed drug can be discharged.

As described above, according to this embodiment, the medicines a and b to be mixed are stored in the inner containers 15 and 16, respectively, and the inner containers 15 and 16 are stored in the container body 4. Even if the medicine outlet 32 is accidentally opened before the container body 4 is pressed, the medicine can be prevented from being discharged. Further, since the container 1 is manufactured by preparing inner containers 15 and 16 in which medicines are stored in advance and storing them in the container body 4, as in the above-described first to third embodiments, There is no need to provide a weak seal portion 20 for partition and a weak seal portion 21 for discharge,
The manufacturing process can be simplified.

It should be noted that the weak sealing portion 23 for sealing is
As in the embodiment, an opening may be provided only in a part of the inner containers 15 and 16, and the opening may be sealed.

In the multi-chamber medical container of each of the above embodiments, 2
Although it is configured to be able to mix different types of medicines, the present invention is not limited to this, and may be provided with two or more storage units or two or more inner containers.

[0055]

As is clear from the above, the present invention (first embodiment)
According to the multi-chamber medical container of the invention), in the structure in which the partitioning weak seal portion and the discharge weak seal portion are opened by increasing the pressure in the storage portion, it is necessary to open the discharge weak seal portion. By setting the pressure to be higher than the pressure required to open the partition weak seal portion, after the partition weak seal portion is opened, the discharge weak seal portion is opened and the mixed drug is dispensed with the drug. It is ensured that it is discharged from the outlet.

The container body is formed of a mixed material of polyethylene and polypropylene, and the partition weak seal portion and the discharge weak seal portion are formed by heat-sealing the film surfaces on both sides of the container body. The difference in heating temperature, pressure, etc. at the time of fusion of the seal portion is provided, and the fusion strength of the weak seal portion for discharge is smaller than the fusion strength of the peripheral portion of the container body,
In addition, by adopting a configuration that is larger than the fusion strength of the partition weak seal portion, it is ensured that the mixed medicine is discharged from the medicine discharge port.

Further, according to the multi-chamber medical container of the present invention (the second invention), the pressure required to open the weak discharge seal is the pressure required to open the weak seal partition. With the configuration equivalent to the above, the partition weak seal portion and the discharge weak seal portion can be formed by fusing under the same conditions, and the discharge weak seal portion can be formed before the partition weak seal portion is opened. It is possible to prevent only the weak seal portion from being opened.

Further, according to the medical double-chamber container of the present invention (third invention), the medicine container of the outer container is provided with an inner container containing one medicine, and the medicine container is formed by the weak seal portion for discharge. Since the medicine outlet is separated from the medicine outlet, for example, even if the user inserts a puncture needle into the medicine outlet before mixing the medicine and tries to take out the medicine, the medicine before mixing does not flow out. Can be prevented. In addition, since the strength of the pressure necessary for peeling the weak seal portion for discharge is higher than the weak seal portion for sealing the inner container, when the pressure in the multi-chamber container is increased, the weak pressure for discharge is reduced. Prior to the sealing portion, the sealing weak sealing portion can be peeled off. As a result, only the medicine after mixing can be discharged from the medicine outlet.

According to the multi-chamber medical container of the present invention (the fourth invention), the medicines to be mixed are stored in the inner containers, respectively.
Since these inner containers are housed in the outer container, it is possible to prevent the medicine before mixing from being discharged even if the medicine discharge port is accidentally opened before mixing the medicine. it can. In addition, in this multi-chamber container, since the inner container in which the medicine is stored in advance is prepared and these are stored in the outer container, the manufacturing process can be simplified.
