Description

  The present invention relates to a medical multi-chamber container. More specifically, the medical multi-chamber container prevents the drug solution from being administered to the human body without being prepared.

  There are drugs and chemicals that have poor storability due to alteration when stored in a premixed state. These drugs and drug solutions are stored separately and mixed and used by aseptic mixing immediately before use. A medical multi-chamber container is used to store drugs and chemical solutions individually during storage and to aseptically mix these drugs and chemical solutions during use.

  This is because a plurality of medicines and chemical solutions are stored separately in a plurality of chambers partitioned by weak seal parts that can be easily peeled off, and the weak seal parts are removed by pressing the container by hand immediately before drug administration. The contents are exfoliated and the contents are mixed or dissolved under aseptic conditions by communicating with a plurality of chambers.

  Such a medical multi-chamber container can be stored in a sterile and stable state until a separately stored drug is opened, but forgets to open and only the drug on the port side is administered, not the prepared drug. There is a possibility that.

  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, a multi-chamber container disclosed in Japanese Patent Application Laid-Open No. 2007-175396 has a hard cover attached to a port so that an administration device such as an infusion line cannot be connected to the port. When the multi-chamber container communicates, the liquid moves from the upper chamber to the lower chamber (port side chamber), and can be detached by expanding the container.

  However, since the administration preventing mechanism in the non-communication state described above is composed of a hard member, it is affected by the shape of the attached port. That is, it is difficult to attach to a multi-chamber container with different port specifications. Therefore, the administration prevention mechanism is a soft cover, and the soft cover is shrunk to cover the lower chamber with each port, and the liquid moves from the lower chamber to the upper chamber during communication, reducing the cross-sectional area of the lower chamber. A multi-chamber container that can be detached by use has been proposed (Patent Document 1).

JP-A-2005-212558

  The thing of the type which covers the whole lower chamber like patent document 1 needs to be transparent so that it can confirm whether the chemical | medical agent in a chemical | medical solution container has denatured before administration. However, because the cover is transparent, it is obstructed by the cover from penetrating the infusion line into the port, but it is difficult to grasp whether the cover is provided to prevent uncontrolled communication, and the cover is soft. Since it is possible to grasp the position of the port, it is possible to connect the administration device if forcible.

  Therefore, it is not affected by the shape of the port at the time of mounting, and it is difficult to grasp the position of the port when it is not in communication, and administration in an unconnected state where it is impossible to connect an administration device can be prevented. A structure is needed.

  The purpose of the present invention is not affected by the shape of the port during installation, and it is difficult to grasp the position of the port in an unconnected state, and the administration device cannot be connected. An object of the present invention is to provide a medical multi-chamber container having a structure capable of preventing administration.

  Therefore, the present inventors are a medical multi-chamber container containing a medicine, and a plurality of storage chambers in which medicines partitioned by partition means that can be opened by pressing are formed in the container body, Suspension means provided at the upper part of the container main body, and a port provided at the lower part of the container main body so as to communicate with the lowermost chamber among the plurality of storage chambers, for discharging the medicine stored in the storage chamber And at least a liquid agent is sealed in the lowermost chamber, and is provided so as to cover from the lower end of the port to the uppermost portion of the lowermost chamber, at least above the region having the maximum cross-sectional area of the lowermost chamber, and the opening is a container body. And a bag-like soft cover provided in close contact with the outer cover, and the soft cover is opaque at the bottom so that the inside of the lowermost chamber is visible and the position of the port cannot be recognized from the outside. Colored By using a medical multi-chamber container, it is possible to attach the soft cover without being affected by the shape of the port, and until the communication, In the attached state, the position of the port could not be grasped, and it was found difficult to connect the administration device to the port in an unconnected state, and the present invention was achieved.

  The soft cover may be further translucently printed with communication means so that the printing of the container body can be visually recognized.

  Since the medical multi-chamber container of the present invention is attached so as to cover the soft cover, it can be used regardless of the port shape, and since the lower part of the soft cover is opaquely colored, the soft cover is attached. In this state, the position of the port cannot be grasped, and it is difficult to connect the administration device to the port in a non-communication state.

In addition, the soft cover is translucently printed with the communication method, so that it is possible to grasp the printing of the container body itself, to alert the user that communication is not established, and to illustrate the communication method.

The front view of one embodiment of the medical multi-chamber container of this invention. The sectional side view of the medical multiple-chamber container of FIG. The front view of the other embodiment example of the medical multiple-chamber container of this invention.

  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.

  FIG. 1 is a front view of an embodiment of the medical multi-chamber container of the present invention. However, for the convenience of illustration, the opaque portion of the soft cover is indicated by hatching so that the inside thereof can be seen. 2 is a side sectional view of the medical multi-chamber container of FIG. FIG. 3 shows another embodiment of the medical multi-chamber container of the present invention.

  The medical multi-chamber container of the present invention will be described with reference to FIGS. A weak seal portion which is a partitioning means 2 is provided so as to divide the container main body 1 into upper and lower portions, and an upper chamber 3 and a lower chamber 4 are formed by the weak seal portion, and each contains a liquid agent. A suspension hole as suspension means 5 is formed in the upper part of the container body 1, and a port 6 is provided at the lower end provided to communicate with the lower chamber. A soft cover 7 is provided so as to cover the port 6 and the lower chamber 4. The soft cover 7 exists so that the opening is in close contact with the vicinity of the partition means 2. The opening 71 is located above the weak seal portion, that is, above the maximum cross section circumference 41 of the lower chamber 4 and is smaller than the maximum cross section circumference 41, so that the soft cover 7 is stably provided and is not provided. It will not be detached easily. The soft cover 7 has an opaque colored portion 72 below so that the position of the port 6 cannot be visually recognized from the outside. An outline of the communication method may be illustrated on the opaque colored portion.

  As shown in FIG. 2, the maximum transverse section circumference 41 is the circumference of the portion that is most widened in the lower chamber 4, and is formed when the liquid agent is accommodated in the lower chamber 4.

  When the storage chamber in which the liquid agent is sealed is pressed from the outside and the communication operation is performed, the weak seal portion as the partitioning means 2 is peeled off, and the partition of the upper chamber 3 and the lower chamber 4 is eliminated, and the liquid agent moves within the container body. The range in which the container can be deformed is widened. When the liquid agent in the lower chamber 4 is moved to the upper chamber side, the cross-sectional circumference of the lower chamber becomes smaller than the opening of the soft cover 7, so that the liquid agent in the lower chamber 4 is moved to the upper chamber side at the same time. By pulling out, the container body 1 and the soft cover 7 are separated from each other, and the port 6 appears so that it can be administered.

  It is not necessary to color the opaque portion of the soft cover with one color, and printing may be performed. As a coloring method of the opaque portion, for example, it can be achieved by first printing with white ink. In addition, by printing with an arbitrary color, colored opaque printing is also possible. The opaque coloring may be performed so that the puncture position of the port 6 cannot be grasped and the printing of the lower chamber 4 and the visual recognition of the medicine are not hindered. As a preferred example, as shown in FIG. 1, it is formed from the lower end of the soft cover 7 to above the boundary between the lowermost chamber and the port. Further, as shown in FIG. 3, a communication method print (for example, a pressing position and direction) 73 is made translucent above the soft cover so that the medicine information printed on the container body can be confirmed. May be. The semi-transparent communication method printing 73 is optional, but printing is preferable because the operation procedure becomes clear and a warning is given that communication is not established. The print color is not particularly limited, but an eye-catching one such as vermilion is preferable.

Note that the printing of the soft cover 7 and the position of the opening 71 in FIG. 3 are examples of the embodiment of the present invention. The opening 71 of the soft cover 7 only needs to be positioned above the maximum cross-sectional circumference 41 of the lower chamber 4. And since the printing 73 of the communication method printed in the semicircle shape on the side part of the soft cover 7 is translucent, the visual recognition of the printing of the container body is not hindered. Moreover, since there is no printing in the upper center part of the soft cover 7 and it is colorless and transparent, the state of the liquid agent enclosed in the lower chamber 4 can be confirmed before the preparation of the medicine (before use).

  The material of the drug chamber is not particularly limited as long as the drug can be stably stored, and is usually formed of a synthetic resin film used for a drug bag. When the drug is a powder, it is preferable that the drug can be stably stored, has gas / moisture barrier properties, and has excellent bag strength, and has an innermost layer that comes into contact with the drug when the film is formed into a bag shape. Polyethylene and cyclic polyolefin capable of stably storing chemicals, vapor-deposited polyethylene terephthalate with an intermediate layer blocking moisture and gas, and excellent printing strength It is particularly preferable to use a laminated film to be formed. By laminating films in this way, it is possible to block moisture and gas that are going to permeate the synthetic resin. When the drug is a liquid, it is preferable to use polyethylene that is resistant to low temperature impact and excellent in flexibility.

  When the container body 1 is a laminated film made of the same material as the medicine sealed in the upper chamber and the lower chamber, the container body 1 is formed by integral molding and is divided by a weak seal portion so as to be a multiple chamber. Also good. However, the structure of the container body is not limited to FIG. 1 described above. When it is necessary to change the laminated material of the film suitable for drug storage, the first drug chamber and the second drug chamber are separately provided. It is good also as a container main body by manufacturing and connecting. A film formed by dividing the front seat and the rear seat may be bonded together.

  The structure of the weak seal portion 2 is not particularly limited as long as each drug chamber can be partitioned in a liquid-tight manner and each drug chamber can be quickly communicated when the container is pressed. For example, when the innermost layer is a polymer blend of polyethylene and polypropylene, the container body is welded at 200 to 250 ° C., and the weak seal portion forming sheet is welded at around 120 ° C. to form the weak seal portion. Thus, it is possible to achieve a structure in which only the weak seal portion can be peeled without peeling off the peripheral edge of the container due to pressing during communication. When the weak seal portion forming sheet is bitten into the weak seal portion to form the weak seal portion, the innermost layer material and the resin having low welding strength are usually used for the sheet. For example, when the innermost layer is polyethylene, a polymer blend in which polyethylene and polypropylene are mixed at 3: 7 to 7: 3 is suitably employed. By using the resin of the innermost layer and the resin having a weak welding strength, weak seals are possible because the portions not welded to the innermost layer are scattered in the weak seal portion.

  The medicine enclosed in the plurality of storage chambers is not particularly limited as long as at least the lowermost chamber is a liquid agent. The form of the medicine sealed in the chamber other than the lowermost part may be either a liquid agent or a powder agent.

  The suspending means 5 is a suspending hole in FIG. 1, but may be a hook member or the like that can be suspended, and the shape is not particularly limited as long as it can be suspended.

  The port 6 is a cylindrical body, and a plug is attached to the spout at the bottom of the port. Usually, isoprene rubber, butadiene rubber or the like is used as the rubber of the plug.

  The soft cover 7 is provided by contracting the upper or lower drug chamber so that the chamber cannot be detached when the chamber is not in communication, and is formed of, for example, a shrink film made of polyethylene or PET. When the soft cover 7 is attached to the container body 1, it is contracted by heat treatment and tightened, but at this time, depending on the processing conditions, a member that can be partially contracted may be used so as not to contract too much. Is possible. For example, a polypropylene sheet that is a non-shrinkable portion and a PET shrink film that is a shrinkable portion are joined together. By performing the heat treatment, only the shrink film portion made of PET shrinks. By forming it so as to be partially contracted, it is possible to design appropriately so that tightening after contraction is preferable, and it is not difficult to detach due to excessive contraction. Also when attaching, since heat shrinkage is applied after attaching to the multi-chamber container, it can be easily fixed.

  Since the medical multi-chamber container of the present invention is attached so as to cover the soft cover as described above, it can be used regardless of the port shape, and the lower side of the soft cover is opaquely colored. Therefore, the position of the port cannot be grasped with the soft cover attached, and it is difficult to connect the administration device to the port in a non-communication state.
