Description

  The present invention relates to a medical multi-chamber container that can easily determine communication from an external shape.

  2. Description of the Related Art Conventionally, there is a medical multi-chamber container as a container for separately storing a plurality of medicines and chemical solutions that deteriorate or deteriorate when stored in a premixed state. In this product, one drug container is divided into a plurality of drug chambers by a detachable partitioning means such as a weak seal, and at the time of storage, each drug can be stored separately in each drug chamber having poor compatibility, and A container that can be administered by aseptically mixing these drugs by peeling the weak seal at the time of administration, and is widely used.

  Such a multi-chamber container communicates between the chambers by pressing the chambers, and it is common to visually determine whether the chambers communicate with each other. However, it is difficult to distinguish whether a plurality of chambers are in communication, and there has been a report that a medicine enclosed in a medical multi-chamber container is administered to a patient without communication.

  In order to avoid administration of a drug from a multi-chamber container to a patient in an unconnected state, a mechanism has been proposed in which the drug is not administered in an unconnected state. For example, as in JP-A-2005-218661 and JP-A-2006-6707, the multi-chamber container cannot be suspended until it communicates, or the infusion line cannot be connected to the port.

  However, the above-described form is not preferable because unnecessary dust is generated, and therefore, a multi-chamber container having a characteristic in the external shape of the container itself and capable of determining the communication state has been proposed. For example, in the suspended state as described in Patent Document 1, the center of gravity in the state where the liquid chamber for pressing deformation is filled with the liquid is in the state where the liquid chamber is filled with the liquid in the other liquid chamber. It is set as the structure which has shifted | deviated to the thickness direction of the liquid chamber for press deformation | transformation with respect to the gravity center.

  However, when configured as a multi-chamber container in Patent Document 1, when the press deformation chamber is formed in a three-dimensional form so that it can be discriminated, an upper welded portion provided with a partition portion and a hanging hole for partitioning the press deformation chamber The film cannot be formed unless the area of the film forming the press deformation chamber is excessively large relative to the area of the surface sandwiched between the two. An excessively large film causes wrinkles in the container after communication. In addition, the state where the covering member covering the pressure deformation chamber after communication cannot be eliminated cannot be eliminated, and the amount of dust increases.

  The drug in each chamber in the multi-chamber container is adjusted so that the concentration and amount are optimal for patient administration when mixed. However, when the container is wrinkled as described above, a liquid puddle is generated in the container, and it is difficult to optimally mix and administer the entire amount of the medicine in each chamber.

  Therefore, according to the present invention, communication can be discriminated from the appearance and shape, and wrinkles that cause liquid pools after communication are not formed, and the liquid agent contained in each room is optimally mixed and administered in its entirety. An object of the present invention is to provide a multi-chamber container for medical use.

  Therefore, as a result of intensive studies, the inventors have arrived at the following invention. An upper welded portion having a suspension means on the upper part and formed in a planar shape, a lower welded part welded so as to be flush with the upper welded part and provided with a port, and the upper welded part A plurality of chambers for containing a medicine formed between a portion and the lower welded portion, and a weak seal that separates the chambers and can be peeled off by pressing the chamber from the outside. It is a chamber container, and at least one of the weak seals is welded so as not to be coplanar with the plane formed by the upper welded portion, and the appearance shape is changed by peeling of the weak seal. This is a medical multi-chamber container.

  The external shape of the chamber defined by the weak seal welded so as not to be flush with the plane formed by the upper welded portion may be a triangular pyramid shape, and the external shape after the weak seal is peeled off is flattened. You may make it.

  In this way, by providing a weak seal welded so as not to be flush with the plane formed by the upper welded portion between the upper welded portion and the lower welded portion, the container shape can be distinguished from the outer shape. Therefore, it is not necessary to make the area of the film forming the chamber excessively larger than the area of the surface sandwiched between the weak seal that partitions the chamber and the upper welded portion having the hanging hole. For this reason, it was found that no wrinkles were formed in the container after communication, and the present invention was reached.

  In the medical multi-chamber container of the present invention, communication can be discriminated from the external shape, and wrinkles are not formed after communication, so that the total amount of the drug can be administered at an optimal concentration for the patient.

FIG. 1 is a perspective view before communication of an embodiment in the case where two chambers are formed in the medical multi-chamber container of the present invention. FIG. 2 is a top view before communication in the embodiment shown in FIG. FIG. 3 is a perspective view of the medical multi-chamber container after communication. FIG. 4 is a perspective view before communication of an embodiment in the case where three chambers are formed. FIG. 5 is a perspective view before communication of an embodiment in the case where four chambers are formed. FIG. 6 is a perspective view before communication of an embodiment in which the chamber shape is a substantially triangular pyramid shape.

  Hereinafter, the medical multi-chamber container of the present invention will be described with reference to the drawings. However, the present invention is not limited to the exemplary embodiments described in these drawings.

  The medical multi-chamber container of the present invention will be described with reference to FIGS. An upper welded portion (1) formed by closing one opening of a tube-shaped flexible film is formed on the upper portion of the container body, and the upper welded portion has a planar shape and has a suspension hole (2 )have. In the lower part of the container body, a port (3) connectable to the infusion line is sandwiched between the other openings of the tube-like flexible film so as to communicate with the lower chamber, and is flush with the upper welded part as shown in FIG. A lower welded portion (4) is formed by welding as it is formed. One weak seal (5) is provided between the upper welded portion and the lower welded portion, and when viewed from the upper surface of the container, the weak seal is formed with a cross between the upper welded portion and the weak seal as shown in FIG. It is formed to make. By the weak seal, the container body is divided into an upper chamber (6) including an upper welded portion and a lower chamber (7) including a lower welded portion, and each chamber has a triangular pyramid appearance. When the chamber is pressed, the weak seal is peeled off, the chambers are in communication with each other, the medicine contained in each chamber is mixed, and the outer appearance of the container consisting of two triangular pyramid shaped chambers before the weak seal is peeled off The shape is a flat shape as shown in FIG. Thus, by forming a weak seal between the upper welded portion and the lower welded portion that does not form the same plane as the plane formed by the upper welded portion, the chamber shape before communication is a three-dimensional shape, and after communication Therefore, it is possible to determine the communication from the external shape, and the wrinkle is not formed after the communication.

  In the above embodiment, the weak seal is formed so as to form a cross between the upper welded portion and the weak seal when the container is viewed from the upper surface of the container. In such a multi-chamber container, since the shape of the container greatly changes before and after the weak seal is peeled off, it is particularly easy to determine whether or not the chamber is communicated when the chamber is pressed. Since the cone-shaped chamber is formed, it is possible to determine whether the communication state is in the communication state or the non-communication state with a glance even when it is placed on a table or suspended from a hanging device. However, the above embodiment is an example, and if a weak seal that does not form the same plane as the upper welded portion is formed, it is possible to determine the communication from the external shape, and the container after the communication is wrinkled. It becomes a multi-chamber container which is not formed. Therefore, as in the above-described embodiment, at least one of the weak seals defining the chambers of the upper welded portion is not formed so as to form a cross between the upper welded portion and the weak seal when viewed from the upper surface of the container. A weak seal that does not form the same plane as the plane formed may be formed. The weak seal is preferably formed so that the angle α formed by the upper seal portion and the weak seal when viewed from the upper surface of the container is not less than 5 degrees and not more than 175 degrees.

  About formation of a container main body, in the said Example, the container main body is formed in the form of dividing several chambers in one tube-shaped film. However, the present invention is not limited to this, and the container body may be formed using a plurality of tubular films. For example, in one tubular film of two tubular films, one opening is closed with a strong weld (for example, an upper weld), and the other opening is closed with a weak seal, and an excess film is formed under the weak seal. In the other tubular film, only one opening is closed with a strong weld (lower weld), and the two tubular films are connected by the excess film and the opening of the tubular film. One multi-chamber container may be formed from two tubular films by welding to match. Moreover, it does not restrict to using a tube-shaped film about the film which forms a container. For example, the container body may be formed by bonding two films so as to weld four sides.

  In the above embodiment, the number of chambers is two chambers divided by one weak seal, but three or more chambers may be formed by providing two or more weak seals. It is sufficient that there is at least one weak seal that does not form the same plane as the plane to be formed. For example, as shown in FIG. 4, two weak seals that are not coplanar with the plane formed by the upper welded portion, and one weak seal and the other weak seal are coplanar with the upper welded portion. When provided between the lower welding parts, a multi-chamber container in which a flat chamber is formed between two triangular pyramid-shaped chambers can be obtained. Moreover, the container shape as shown in FIG. 5 is also possible, and the multi-chamber container composed of the chambers as shown in FIGS. 4 and 5 presses the chamber, peels off the weak seal, When communicated, a container having a flat outer shape as shown in FIG. 3 is obtained.

  Regarding the shape of the chamber, in the above embodiment, when viewed from the upper surface of the container, the shape of the chamber partitioned by the weak seal is triangular by forming a weak seal so as to form a cross between the upper welded portion and the weak seal. It has a cone shape. However, if a weak seal that does not form the same plane as the plane formed by the upper welded portion is formed, it is possible to determine the communication from the external appearance of the chamber, and it is a multi-chamber container in which wrinkles are not formed after communication. . Therefore, the shape of the chamber is not limited as long as it is a chamber partitioned by a weak seal that does not form the same plane as the upper welded portion. For example, in the embodiment described above, the upper welded portion shape may be formed in a triangular shape as shown in FIG.

  Regarding the shape of the weak seal, the upper welded portion, and the lower welded portion, in the examples, the upper welded portion and the weakly sealed shape are rectangular, and the shape of the lower welded portion is a bow to make sure that the entire amount is easily administered. The shape is a curved line. However, the shape can be changed according to various purposes, and the shape and size are not limited as long as they do not depart from the gist of the present invention.

  The material of the film forming the container is not particularly limited as long as it is suitable for the drug contained in the chamber. For example, film materials are polypropylene, polyethylene, polyethylene terephthalate, polyvinyl alcohol, polyvinyl chloride, ethylene-vinyl alcohol copolymer, ethylene-vinyl acetate copolymer, polycyclic olefin, nylon, polystyrene and other resins, and these resins are mixed. Or a laminated material, or a material other than a resin such as aluminum and a resin may be laminated. Moreover, you may form the multi-chamber container from which the film material for each chamber differs corresponding to the chemical | medical agent accommodated in a chamber.

  As for the suspending means, in the above embodiment, the suspending means is provided with a suspending hole in the upper welded portion. However, any structure can be used as long as it can be suspended by a hanging device. The container may be suspended by providing a hook.

  As for the port, the port is fixed by the lower welding portion so as to communicate with the lower chamber, and supplies the medicine inside the container to the infusion line by connecting the port and the infusion line. In the above-described embodiment, a port in which a rubber stopper capable of penetrating a needle is disposed at an end portion is sandwiched and welded and fixed by a tubular opening. However, the present invention is not limited to the tubular film, and may be welded and fixed so as to be sandwiched between two films. The port may be any port that can supply the drug inside the container to the infusion line by connection with the infusion line, and the configuration and shape thereof are not limited. For example, a membrane tube may be used instead of a port having a rubber plug at the end.

  As for the medicines contained in each room, if the medicine contained in at least one of the plurality of chambers is liquid, the medicines contained in the other indoors are in powder form. It does not matter what the state of the drug is.

  As described above, the medical multi-chamber container of the present invention can be used for medical treatment because it is possible to determine the communication from the external shape and no wrinkles are formed after the communication.
