Description

  The present invention comprises a medical multi-chamber container, and more specifically, a plurality of chambers for individually storing various unstable drugs (liquid, powder, or solid agent) that change with time when mixed at the same time. The present invention relates to a medical multi-chamber container that can mix a medicine stored in each chamber in a sterile state without generating foreign matter by peeling and opening the weak seal portion.

  Among drugs administered to patients by intravenous injection, there are unstable drugs that cause undesirable changes over time when pre-mixed. For example, when an amino acid infusion solution and a glucose infusion solution are blended and stored, the mixed solution browns by a so-called Maillard reaction. Also, if fat emulsion and electrolyte solution are blended and stored, fat will aggregate, and if phosphoric acid-containing liquid and calcium-containing liquid are blended, calcium phosphate will precipitate, causing undesirable changes. And so on.

  For such drugs, medical multi-chamber containers that individually store components before mixing are often used. This medical multi-chamber container is provided with a plurality of storage units that are stored individually, and a partition weak seal unit that partitions the storage unit and can be peeled off by applying pressure from the outside.

  FIG. 12 is a plan view showing an example of such a conventional medical multi-chamber container, and FIG. 13 is a sectional view taken along line XX of FIG.

  In the storage units 10 and 11 of the medical multi-chamber container, various drugs a and b which are undesirable when mixed or dissolved in advance are stored, respectively, and these drugs a and b are isolated by a weak seal 20 for partitioning. It is stored safely and reliably in the used state until it is used. In use, when the storage portion 10 or 11 is pressed, the partition weak seal portion 20 is peeled off, the inside of the storage portions 10 and 11 is in a communicating state, and both drugs a and b can be mixed or dissolved quickly.

  Further, the medical multi-chamber container is provided with a hanging hole 30 at one end and a chemical solution discharge port 32 having a rubber stopper at the other end. When administering a mixed medicine to a patient, the container is suspended from a support column or the like through the hanging hole 30, and then a piercing needle is inserted into a rubber stopper provided at one end of the container, and the tip of the catheter is injected. Administer to the patient through the needle.

  However, such a medical multi-chamber container often stores a liquid agent in the storage portion 11 on the side of the chemical solution discharge port 32, and the rubber seal is attached to the rubber stopper without peeling off the weak seal portion 20 for partitioning. There is a possibility that the liquid medicine is taken out from the chemical liquid outlet 32.

  In order to solve the problems of the prior art, the present invention ensures that the medicines stored in the respective storage portions are mixed and then administered to the patient, and the medicine is administered to the patient without being mixed by mistake. It is an object of the present invention to provide a medical multi-chamber container capable of reliably preventing an accident.

  The object of the present invention is to provide a plurality of storage portions, a weak seal portion for partitioning the storage portions, a medicine discharge port connected to the storage portion, and at least one of the storage portion and the medicine discharge port. A discharge weak seal portion that partitions the liquid medicine, and liquid medicine is stored in at least one of the plurality of storage portions, and the partition weak seal portion and the discharge weak seal portion increase the pressure in the storage portion. The medical multi-chamber container is characterized in that the pressure necessary for opening the weak seal portion for discharging is larger than the pressure necessary for opening the weak seal portion for partitioning. (First invention).

  The container body is formed of a mixed material of polyethylene and polypropylene, and the weak seal portion for partition and the weak seal portion for discharge are formed by heat-sealing the film surfaces on both sides of the container body, and the weak discharge portion is formed. It is possible that the fusion strength of the seal portion is smaller than the fusion strength of the peripheral portion of the container body and greater than the fusion strength of the weak seal portion for partition.

  Alternatively, the subject of the present invention is a plurality of storage portions, a weak seal portion for partitioning the storage portions, a medicine discharge port connected to the storage portion, at least one of the storage portion and the medicine discharge port. And a liquid medicine is stored in at least one of the plurality of storage portions, and the partition weak seal portion and the discharge weak seal portion increase the pressure in the storage portion. The medical multi-chamber container is characterized in that the pressure required to open the discharge weak seal portion is equal to the pressure required to open the partition weak seal portion. (Second invention).

  The partition weak seal portion may be formed to include at least one projecting portion projecting from the housing portion.

  The discharge weak seal portion is formed in an arc shape so that the discharge weak seal portion surrounds the medicine discharge port in the vicinity thereof, and the partition weak seal portion is housed from the discharge weak seal portion. It is also possible to form it in an arc shape so as to surround the discharge seal portion with an interval necessary for formation.

  Further, the object of the present invention is to provide at least one inner container that contains a medicine and is sealed by a weak sealing portion for sealing, and an outer container that contains the inner container and contains the medicine outside the inner container. And a medicine discharge port connected to the outer container, and a weak discharge part for discharging partitioning between the medicine container and the medicine outlet in the outer container, and at least one of the medicine container and the inner container The liquid medicine is stored in the container, and the weak sealing portion for sealing and the weak sealing portion for discharging are opened by increasing the pressure in the inner container and the medicine storing portion, respectively, and the weak sealing portion for discharging is opened. It is also achieved by a medical multi-chamber container characterized in that the pressure required to do this is greater than the pressure required to open the weak sealing portion for sealing (third invention).

  Furthermore, the problems of the present invention are a plurality of inner containers in which a medicine is stored and sealed by a weak sealing portion for sealing, an outer container for storing the plurality of inner containers, and a medicine connected to the outer container. A liquid medicine is stored in at least one of the plurality of inner containers, and the weak sealing portion for sealing is opened by increasing the pressure in the inner container. This can also be achieved by a multi-chamber container (fourth invention).

  As is clear from the above, according to the medical multi-chamber container of the present invention (first invention), in the structure where the partition weak seal part and the discharge weak seal part are opened by increasing the pressure in the storage part, Since the pressure required for opening the discharge weak seal portion is larger than the pressure required for opening the partition weak seal portion, the discharge weak seal portion is opened after the partition weak seal portion is opened. The seal portion is opened, and it is ensured that the mixed medicine is discharged from the medicine discharge port.

  The container body is formed of a mixed material of polyethylene and polypropylene, and the weak seal part for partition and the weak seal part for discharge are formed by heat-sealing the film surfaces on both sides of the container body. There is a difference in heating temperature, pressure, etc. at the time of fusing, the fusing strength of the discharge weak seal portion is smaller than the fusing strength of the peripheral portion of the container body, and the fusing strength of the weak sealing portion for the partition By setting it as a big structure, it will become reliable to discharge | emit the medicine after mixing from a medicine discharge port.

  Further, according to the medical multi-chamber container of the present invention (second invention), the pressure required for opening the discharge weak seal portion is equal to the pressure required for opening the partition weak seal portion. By having a certain configuration, the partition weak seal portion and the discharge weak seal portion can be fused and formed under the same conditions, and the discharge weak seal portion is opened before the partition weak seal portion is opened. Only can be prevented from being opened.

  Further, according to the medical multi-chamber container of the present invention (third invention), the medicine container of the outer container is provided with the inner container containing one medicine, and the medicine container and the medicine discharge part are disposed by the weak discharge part for discharge. Since the outlet is partitioned, for example, even when a puncture needle is inserted into the medicine discharge port before mixing the medicine and the medicine is taken out, the medicine before mixing is prevented from flowing out. Can do. In addition, since the strength of the pressure required for peeling the discharge weak seal portion is higher than the weak seal portion for sealing the inner container, when the pressure in the multi-chamber container is increased, the discharge weakness is reduced. Prior to the sealing portion, the weak sealing portion for sealing can be peeled off. As a result, only the mixed drug can be discharged from the drug discharge port.

  Also, according to the medical multi-chamber container of the present invention (fourth invention), the medicines to be mixed are stored in the inner containers, and these inner containers are stored in the outer container. Even when the medicine discharge port is opened by mistake, the medicine before mixing can be prevented from being discharged. In addition, since the multi-chamber container is manufactured by preparing an inner container in which a medicine is stored in advance and storing them in the outer container, the manufacturing process can be simplified.

  Hereinafter, embodiments of a medical multi-chamber container according to the present invention will be described with reference to the drawings. In the following description, the same code | symbol is attached | subjected to the same or the same kind part through several embodiment.

  (First Embodiment) A medical multi-chamber container according to a first embodiment of 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 medical multi-chamber container 1 includes a container body 3 having a peripheral edge 2 fused and formed in a rectangular shape, and a first storage section 10 arranged side by side in the longitudinal direction of the container body 3. And the second storage portion 11, the peelable partition weak seal portion 20 that partitions the two storage portions 10, 11, the medicine discharge port 32 that is connected to the second storage portion 11 and has the rubber plug 31, and the second storage. A dischargeable weak seal portion 21 is provided that separates between the portion 11 and the medicine discharge port 32. Each of the storage units 10 and 11 stores various drugs a and b, which are undesirable when mixed or dissolved in advance.

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

  The partition weak seal portion 20 and the discharge weak seal portion 21 are formed to be openable in various ways. For example, both the sides of the film forming the medical multi-chamber container 1 can be bonded by thermal fusion to form the partition weak seal portion 20 and the discharge weak seal portion 21. The discharge weak seal portion 21 can be formed in parallel with the partition weak seal portion 20 as shown in FIG. 1. For example, as shown in FIG. 3, the discharge weak seal portion 21 has an arc shape around the medicine discharge port 32. It can also be formed.

  The pressure required to open the discharge weak seal portion 21 is set to be larger than the pressure required to open the partition weak seal portion 20. Thereby, when pressing each storage part and mixing the medicines a and b, since the partition weak seal part 20 is opened before the discharge weak seal part 21, only the discharge weak seal part 21 is opened. Can be prevented. Furthermore, it is possible to reliably prevent accidents in which the medicine is administered to the patient without mixing the medicine by mistake. Preferably, the difference in opening strength (weight when pressing the medical multi-chamber container) required for peeling the discharge weak seal portion 21 and the partition weak seal portion 20 is about 5 kg to about 10 kg.

  As described above, according to the present embodiment, the medicines stored in the storage units 10 and 11 are adjusted by adjusting the pressure necessary for peeling the discharge weak seal portion 21 and the partition weak seal portion 20. When a and b are mixed, the discharge weak seal portion 21 can be peeled off after the partition weak seal portion 20 is peeled off.

  That is, the mixing or dissolution of the drugs a and b stored in the storage units is completed before the discharge weak seal portion 21 is peeled off and the drug can be administered to the patient. Therefore, it is possible to discharge the mixed medicine reliably from the medicine discharge port 32.

  Various methods can be used to adjust the pressure required to peel the discharge weak seal portion 21 and the partition weak seal portion 20 from each other. For example, by forming the container body from polyethylene (PE), the fusion strength of the discharge weak seal portion 21 is smaller than the fusion strength of the peripheral edge portion 2 of the container body, and the fusion weak seal portion 21 is fused. It can be greater than strength.

  In order to provide such a difference in 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 heat fusion time of the partition weak seal portion is reduced. It must be longer than the arrival time. Alternatively, the fusion strength is adjusted by performing the fusion pressure of the discharge weak seal portion at a pressure lower than the fusion pressure of the peripheral edge portion 2 of the container body and higher than the fusion pressure of the partition weak seal portion. Is possible.

  In this way, by adjusting the fusion strength in each part of the multi-chamber container, it is possible to prevent only the discharge seal portion 21 from being opened first. This ensures that the mixed drug is discharged from the drug discharge port 32. In addition, as described later, the partition weak seal portion 20 can be opened first by adjusting the widths of the seal portions 20 and 21.

  Since the peripheral edge 2 of the container main body 3 has higher fusion strength than the weak seal part 21 for discharge, the peripheral part 2 of the container main body 3 must be opened even after the weak seal part 21 for discharge is opened. Is prevented, and the chemical liquid is prevented from leaking from the storage units 10 and 11.

  Alternatively, the pressure necessary for peeling the discharge weak seal portion 21 may be equal to the pressure necessary for peeling the partition weak seal portion 20. Thus, the partition weak seal portion 20 and the discharge weak seal portion 21 are opened almost simultaneously, and only the discharge weak seal portion 21 is not opened. Can be mixed.

  Further, by making the pressures necessary for opening the partition weak seal portion 20 and the discharge weak seal portion 21 substantially the same, the partition weak seal portion 20 and the discharge weak seal portion 21 Can be formed by fusing under the same conditions, so that the multi-chamber container 1 can be easily manufactured. In particular, in a multi-chamber container in which the powder agent is stored in the second storage unit 11 on the drug discharge port 32 side and the chemical solution is stored in the first storage unit 10, the first storage unit 10 on the side far from the chemical solution discharge port 32. Since the partition weak seal portion 20 is opened and the chemical solution and the powder agent are surely mixed, only the discharge weak seal portion 21 is opened before the partition weak seal portion 20 is opened. Can be prevented in advance.

  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 disposed outside the discharge weak seal portion 21. The first storage part 10 is formed in the upper part of the container body 3 and the second storage part 21 is formed in the lower part. The same effects as described above can be obtained by configuring the seal portions 20 and 21 in this way.

  In the present embodiment, the two storage portions 10 and 11 are arranged side by side in the longitudinal direction of the container main body 3, but may be arranged side by side in a direction crossing the longitudinal direction, for example, as shown in FIG. As shown in the figure, the medical multi-chamber container 1 is provided with an inverted V-shaped discharge weak seal portion 21 so as to surround the medicine discharge port 32. And the partition weak seal part 20 formed in the width | variety narrower than the discharge weak seal part 21 is extended in the longitudinal direction of the container main body 3 from the top part of this weak seal part 21 for discharge to the peripheral edge part 2 which opposes. A first storage portion 10 is formed on the left side of the main body 3, and a second storage portion 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 edge portion 2 on the side of the container body 3. desirable. By providing such a guide seal portion 22, all of the medicine stored in the first storage portion 10 can flow into the second storage portion 11 when the partition weak seal portion 20 is peeled off.

  In this medical multi-chamber container 1, by making the width of the discharge weak seal portion 21 wider than the width of the partition weak seal portion 20, the peeling strength of the discharge weak seal portion 21 is increased, and the partition weak seal is thus obtained. The portion 20 is peeled off before the discharge weak seal portion 21. Therefore, since the difference in the peel strength between the weak seal portions 20 and 21 can be provided while keeping the same fusion time or pressure in the weak seal portions 20 and 21, the manufacturing time of the container 1 can be shortened. And manufacturing costs can be reduced. In order to provide such a peel strength 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 employed.

  As described above, the width of the guide seal portion 22 is wider than the width of the discharge weak seal portion 21 so that the guide seal portion 22 is not easily peeled off. Therefore, for example, as shown in FIG. 6, a portion surrounded by the guide seal portion 22 and the peripheral edge portion 2 may be fused and the guide seal portion 22 may be integrated with the peripheral edge portion 2.

  (Second Embodiment) A second embodiment of the medical multi-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 action of the protruding portion, and FIG. 8B is a plan view of FIG. It is AA sectional view.

  The main difference between the second embodiment and the first embodiment described above is that a protrusion is provided to relatively reduce the pressure required for peeling off the partition weak seal. is there.

  As shown in FIG. 7, in this medical multi-chamber container 1, the partition weak seal portion 20 and the discharge weak seal portion 21 are formed with the same width, and with the same fusion time and fusion pressure. It is fused. Moreover, the partition weak seal part 20 is provided with a protrusion 20a formed in a V shape in the middle thereof, and the partition weak seal part 20 is discharged by the protrusion 20a as shown below. It can be opened before 21.

  As shown in FIG. 8A, when the pressure in the storage portions 10 and 11 is increased, the pressure acts on the partition weak seal portion 20 in the direction of the arrow in the figure. At this time, the pressure acts perpendicularly and equally to the seal portion 20, so that the total pressure acting on the region near the top B of the protruding portion 20 a is higher than the other regions of the seal portion 20. Thus, as shown in FIG. 8 (b), this pressure acts in the direction of separating the films constituting the container body 3, and when the pressure in the storage portions 10 and 11 is increased, the partition weak seal portion 20 is Peeling starts from the top B of the protrusion 20a. Thereby, peeling progresses rapidly under the action of a pressure, the 1st accommodating part 10 and the 2nd accommodating part 11 connect, and the chemical | medical agents a and b are mixed. When the container body 3 is further pressed subsequently, 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 this embodiment, since the discharge weak seal portion 20 is provided with the V-shaped protruding portion 20a, the partition weak seal portion 20 and the discharge weak seal portion 21 are formed with the same width. Even when they are fused at the same fusing temperature and fusing pressure, when the pressure is applied to the storage parts 10 and 11, the protruding part 20a starts to peel off first, and the discharge weak seal part Prior to 21, the partition weak seal portion 20 can be opened. As a result, after the medicines a and b stored in the storage parts 10 and 11 are reliably mixed, the discharge weak seal part 21 can be opened, and the mixed medicine is discharged from the medicine discharge port 32. Can be made.

  Moreover, in this embodiment, since only the shape of the partition weak seal portion 20 is changed, the pressure required for peeling off the weak seal portions 20 and 21 can be adjusted. It is not necessary to adjust the fusing time, etc., and both weak seal portions 20, 21 can be fused under the same conditions. As a result, the manufacturing time of the container 1 can be shortened and the manufacturing cost can be reduced. In particular, since the partition weak seal portion 10 and the discharge weak seal portion 11 are formed with the same width, it is possible to eliminate unevenness in fusion, and the weak seal portions 10 and 11 as a whole can be melted uniformly. Can be worn.

  In the present embodiment, the protruding portion 20a is formed in the medical multi-chamber container 1 in which the storage portions 10 and 11 are arranged in the longitudinal direction of the container body 3, and this protruding portion 20a is shown in FIG. 9, for example. Thus, it goes without saying that the present invention can be applied even when the storage units 10 and 11 are arranged in a direction crossing the longitudinal direction of the container body 3. Further, the number of the protrusions 20a is not limited to one, and as shown in the figure, a plurality of protrusions 20a may be provided, or the direction in which the V-shaped top portion faces may be changed.

  Further, the shape of the protruding portion is not limited to the V shape, and may be a shape provided with a protruding portion on which pressure tends to concentrate.

  (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 provided with a bag-shaped inner container in which at least one of the drugs to be mixed is housed in the container body without providing the partition weak seal portion. This is different from the embodiment.

  As shown in FIG. 10, this medical multi-chamber container 1 is provided with an arc-shaped discharge weak seal portion 21 surrounding the medicine discharge port 32, and the peripheral portion of the container body 4 as an outer container is provided by this seal portion 21. The medicine container 12 surrounded by 2 and the medicine discharge port 32 are partitioned. The medicine storage unit 12 directly stores one of the two kinds of medicines to be mixed, and stores an inner container 13 formed in a bag shape. The inner container 13 includes a sealing weak seal portion 23 formed by laminating two films and fusing the peripheral portion 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 peel off at a low pressure.

  And when mixing a chemical | medical agent, if the container main body 4 is pressed, a pressure will also act on the inner container 13 accommodated in the inside, and the pressure in the inner container 13 will increase. As a result, the sealing weak seal portion 23 is peeled off prior to the discharge weak seal portion 21, and the drug b stored in the inner container 13 diffuses into the drug storage portion 12 of the container body 4. mixed with a. Thereafter, when the puncture needle is inserted into the drug discharge port 32, the mixed drug can be discharged.

  As described above, according to the present embodiment, the medicine container 12 and the medicine discharge port 32 are partitioned by the discharge weak seal portion 21, so that the medicine discharge port 32 is erroneously opened before the medicine is mixed. Even if it is a case, it can prevent that the chemical | medical agent before mixing flows out. Further, since the pressure required for peeling the discharge weak seal portion 21 is higher than that of the sealing weak seal portion 23, when the container body 4 is pressed, the sealing is performed prior to the discharge weak seal portion 21. The weak seal part 23 for a stop can be peeled. As a result, when the discharge weak seal portion 21 is peeled off, the sealing weak seal portion 23 is already peeled and the medicine is mixed, so that only the mixed medicine is discharged from the medicine discharge port 32. can do. Furthermore, unlike the first or second embodiment described above, it is not necessary to provide the partition weak seal portion 20, so that the manufacturing process can be simplified.

  In the present embodiment, the peripheral edge of the inner container 13 is used as the weak sealing part 23 for sealing. However, the present invention is not limited to this. For example, an opening is provided only in a part of the inner container 13, and this opening is You may provide the weak seal part for sealing so that it may seal.

  (Fourth Embodiment) A fourth embodiment of the medical multi-chamber 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.

  In the medical multi-chamber container according to the present embodiment, the discharge container and the partition weak seal part are not provided, and the container body is provided with an inner container containing a medicine to be mixed. It is different from the form.

  As shown in FIG. 11, this medical multi-chamber container 1 includes two bag-shaped containers each containing medicines a and b to be mixed in a storage part 14 surrounded by a peripheral part 2 of a container body 4 as an outer container. Inner containers 15 and 16 are accommodated. The inner containers 15 and 16 are each provided with a weak seal portion 23 for sealing formed by laminating two films and fusing the peripheral portions thereof, and the medicines a and b are accommodated therein. The inner containers 15 and 16 are formed in a rectangular shape, and the weak seal portions 23 for sealing the inner containers 15 and 16 are fused with substantially the same strength.

  When mixing the medicine, when the container body 4 is pressed, a pressing force is applied to the inner containers 15 and 16 accommodated therein, and the pressure in the inner containers 15 and 16 is increased. When the container main body 4 is pressed in this way, the respective weak sealing portions 23 for sealing are peeled off almost simultaneously, and the drugs a and b stored in the inner containers 15 and 16 are transferred to the storage portion 14 of the container main body 4. It diffuses and the two drugs a and b are mixed. Subsequently, when the puncture needle is inserted into the drug discharge port 32, the mixed drug can be discharged.

  As described above, according to the present embodiment, the medicines a and b to be mixed are stored in the inner containers 15 and 16, respectively, and these inner containers 15 and 16 are stored in the container body 4. Even when the medicine discharge port 32 is accidentally opened before pressing 4, the medicine can be prevented from being discharged. In addition, since the container 1 is manufactured by preparing the inner containers 15 and 16 in which medicines are stored in advance and storing them in the container body 4, as in the first to third embodiments described above, It is not necessary to provide the partition weak seal portion 20 and the discharge weak seal portion 21, and the manufacturing process can be simplified.
