Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a medical multi-chamber container having an opening confirmation seal.

[0002]

[Prior art and its problems]

 As shown in FIG. 9, the present applicant has previously separated a plurality of, for example, two chambers a and b containing a liquid agent, a powder agent or a solid agent, and separating the chambers a and b by increasing the pressure inside the chamber. A multi-chamber medical container having a weak seal portion c that can be formed has been proposed (see, for example, Japanese Patent Publication No. Hei 4-364850).

Each of the chambers a and b of the multi-chamber container contains a drug d and e that are unstable when mixed or dissolved in advance, and the drugs d and e are sealed by a weak seal portion c. It is safely and securely stored in an isolated state until use. When at least one chamber a or b is pressed during use to increase the chamber pressure, the weak seal portion c separates and both chambers a and b are in a communicating state, and both drugs d and e can be rapidly mixed or dissolved. By the way, the chamber a containing the powder or solid drug d is covered with a cover f for the purpose of absorbing moisture and / or preventing oxidation, and in the space g between the cover f and the chamber a, A desiccant h and an oxygen absorber i are contained.

The multi-chamber container is for storing the unstable ones which are unstable when mixed or dissolved in this way, and is divided into two or more chambers for storage. It is stored and transported in a folded form at the seal portion c. However, even with such consideration, when this container is dispensed from the pharmacy department, or when nurses, pharmacists and doctors handle this container in the ward, it may be stretched beforehand. This not only risks the weak seal to be accidentally peeled and opened long before it is used, but it is not easy to visually check in the case of localized peeling and opening, and this is equivalent to administration to the patient. There is a risk that the drugs will be mixed or dissolved in advance and change over time, resulting in accidental administration of the drug to the patient whose safety is not guaranteed for the patient.

The present invention has been made for the purpose of eliminating such conventional problems.

[0006]

[Means for solving problems]

 The present invention is a multi-chamber container having a plurality of chambers containing a liquid agent, a powder agent, or a solid agent, and a weak seal portion separating the chambers from each other and capable of being peeled off by increasing the room pressure. And a multi-chamber container for medical treatment provided with an unsealing confirmation seal, characterized in that the multi-chamber container is constrained in an unextensible state by an unsealing confirmation seal in a folded state at a weak seal portion. .

[0007]

[Action]

 In the present invention, since the multi-chamber container is folded at the weak seal portion and is constrained to be unextensible by the seal for opening confirmation, the folded state can be held stably and securely until just before use. Prior to the last minute, the risk that the weak seal part may be expanded so that it may be peeled and opened may be eliminated, and the confirmation seal may prevent the multi-chamber container from being expanded. It is a guarantee, and by checking the seal, it can be used with confidence, and the risk of accidentally administering to the patient what was exfoliated mixed or dissolved before immediately before use can be prevented.

【Example】

 Various embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, a two-chamber type multi-chamber container 1 is folded in two at a weak seal portion 2 for partitioning between two chambers, and a tape-shaped opening confirmation seal 3 is used to extend the container. An example of the implementation of the present invention in the case of being restrained to be impossible is shown.

In the present embodiment, the tape-shaped seal 3 is bridged between the end portions 1 a, 1 a facing each other on one end side of the folded multi-chamber container 1, and the end portion 1 a 1a is bonded and fixed at the joints 3a, 3a at both ends to prevent the ends 1a, 1a from opening. Therefore, the multi-chamber container 1 is stably and reliably held in the folded state by the tape-like seal 3.

The multi-chamber container 1 is transported and stored in the folded state shown in FIG. 1, further carried out to the medical field, and held in the folded state until just before use.

The weak seal portion 2 of the multi-chamber container 1 is a portion where the sealing strength is weaker than that of the peripheral seal portion 2a, and it is possible to peel and open by intensively increasing the pressure in one chamber of the multi-chamber container 1. It has a simple structure. If the multi-chamber container 1 is folded in two at the weak seal portion 2, the weak seal portion will have the same sealing strength as the other seals that make up the bag, and will temporarily increase the room pressure. It can be asserted that there is almost no possibility of peeling and opening even if external force is applied. Therefore, if the multi-chamber container 1 is folded and folded in two for transportation and storage, and if it is carried out to the medical site and left as it is until just before use, it may be accidentally subjected to heavy pressure. Even if there is, there is no risk that the weak seal portion 2 is peeled off and opened.

Further, as long as the seal 3 is attached in a normal state, it is a proof that the multi-chamber container 1 has never been stretched between transportation and storage and immediately before use, and is not stretched. As far as possible, the weak seal portion 2 is not peeled and opened first, so that it can be used with confidence.

In use, the tape-shaped seal 3 is broken, for example, at the bridge portion 3b. Therefore, the multi-chamber container 1 is released from the restraint in the folded state, and can be immediately brought into the extended state necessary for peeling and opening the weak seal portion 2.

In order to easily break the tape-shaped seal 3, a broken part such as a perforation 4 and a notch can be formed in the bridge part 3b.

As shown in FIGS. 2 to 3, instead of providing a break in the bridge 3 b, at least one joint end 3 a of the tape-shaped seal 3 is provided with a peelable seal 5 that cannot be re-attached. You may fix to the one end part 1a of the chamber container 1.

As shown in FIG. 4, the opening confirmation seal may be in the form of a string, and the string-like seal 3'is in the form of a loop, one end of which is the hanging hole 6 and the other end of which is a mouth part. It is locked at 7 respectively. As shown in FIG. 5, the loop-shaped string-shaped seal 3 ′ may be used in the shape of a figure 8 in order to secure the locking to the mouth portion 7 more securely.

FIG. 6 shows an enlarged view of the mouth portion 7 part of FIG. 4, and a notch 8 is formed in the middle of the loop-shaped seal 3 ′ to facilitate breakage. Instead of the notch 8, a perforation or a welding seam 9 having a weak adhesive strength as shown in FIG. 7 may be used.

In the present invention, the multi-chamber container 1 is not limited to the structure proposed by the applicant shown in FIG. 9, and the desiccant h and / or the oxygen scavenger i can be obtained from the structure shown in FIG. May be omitted, or may have a structure in which the cover f is omitted. In short, a plurality of chambers and weak seal portions formed between the chambers are provided, and It only needs to be configured so that it can be folded at the section.

The material for the opening confirmation seals 3 and 3'is not particularly limited as long as it has strength as a sealing material, but is usually paper, and if necessary, biaxially stretched synthetic resin (eg PET, nylon). , OPP, HDFE, L-LDPE, LDPE, etc.), metal foil such as aluminum foil, elastomers, raw rubber, etc. as raw materials, and these raw materials are processed alone or in combination into tapes, strings, etc. Used.

Adhesive fixing means of the tape-shaped seal 3 to the multi-chamber container 1 and further adhesive fixing means of the end portions of the string-shaped seal 3'may differ depending on the material and the structure. In this case, the welding means may be used, and in other cases, an appropriate adhesive may be applied to fix the adhesion. However, an adhesive means capable of re-adhesion is not preferable in the present invention.

As the material of the peeling seal 5, paper, cotton, non-woven fabric, P. P non-woven fabric, other thin film metals, synthetic resins, etc. are suitable, and those that can be peeled off by heat welding or the application of an appropriate adhesive, and those that can be re-adhered such as adhesives are not suitable.

The multi-chamber container of the present invention may be transported and stored in an outer bag 10 as shown in FIG. 8, and may be further transported to a medical site.
