Description

  The present invention relates to an infusion container for mixing and administering two or more components to a patient. In particular, the present invention relates to an infusion container that can be used by aseptically mixing a drug solution and a drug immediately before use and can be applied to a home medical patient.

  Conventionally, infusions containing reducing sugars and amino acids, and infusions containing easily degradable amino acids such as L-tryptophan and L-cysteine are decomposed and colored at the time of manufacture (at the time of heat sterilization such as high-pressure steam sterilization) or during storage. In order to prevent this, 1) the pH of the infusion solution is adjusted to the range of 3.0 to 6.0 and sulfite is added as a stabilizer, and 2) it has a peelable partition wall. What is used as a two-chamber container (Japanese Patent Laid-Open No. 63-19149), or drugs that are easily affected by pH or stabilizer sulfites, such as vitamins and antibiotics, 3) And a kit (Japanese Patent Laid-Open No. 10-24088) and 4) a prefilled syringe for mixing immediately before use (Japanese Patent Laid-Open No. 7-51369) have been proposed.

However, the conventional container has room for improvement in application to the convenience of drug addition and home medical care.
Therefore, the problem of the present invention is that when adding other drugs to the drug solution, for example, when adding vitamins, antibiotics, etc. to electrolyte solution, amino acid solution, high calorie solution and enteral nutrition, etc. An object of the present invention is to provide an infusion container that can be prepared safely and conveniently without decomposition of the added drug.

That is, the present invention solves the above-mentioned problems by providing empty containers in these existing containers and providing the following infusion containers.
1) A plurality of compartments separated in a liquid-tight manner by isolation means that can communicate with a bag made of a thermoplastic resin film, a discharge part in one of the plurality of compartments, and an injection part in one of the other compartments In the infusion container thus formed, a chemical solution or a solid agent is accommodated in the compartment having the discharge part, and the compartment having the injection part is an empty container.
2) In an infusion container in which a discharge part is formed in a first compartment and an injection part is formed in a second compartment of two compartments separated liquid-tightly by a separating means that can communicate with a bag made of a thermoplastic resin film. The infusion container is characterized in that a chemical solution is stored in the first compartment, the second compartment is an empty chamber, and the separating means is released by an internal pressure generated by pressing one of the compartments from the outer surface. is there.
3) A discharge part is provided in the first compartment of the three compartments separated in a liquid-tight manner by a separating means that can communicate with a bag made of a thermoplastic resin film, a fixed end part in the second compartment, and an injection part in the third compartment. In the formed infusion container, the first compartment and the second compartment contain a chemical solution or solid agent, the third compartment is an empty room, and the separating means is generated by pressing one of the compartments from the outer surface. An infusion container which is released by internal pressure.
4) The infusion container characterized in that the isolation means is a heat seal formed by heating and pressing inner walls of a bag made of a thermoplastic resin film.
5) The infusion container is characterized in that the compartment is maintained at a pH of 3.0 to 6.0 and contains an infusion containing sulfite as a stabilizer.

  The isolation means 1 is heat sealed. Adjustment of the heat seal strength is not particularly limited, but can be adjusted by changes in the seal temperature, seal time, and seal pressure, and by the width and depth of the heat seal portion. Further, the isolation means is not particularly limited, and is formed on a heat seal formed by heating and pressing inner walls of a bag made of a thermoplastic resin film, a seal bar sandwiched from the outer surface of the bag, or an isolation part. Click chip to be used.

  Moreover, it does not specifically limit as a formation method of the heat seal of the isolation means 1 in an infusion container, It can carry out using the heat seal bar etc. which are used normally. Alternatively, a method may be used in which autoclave sterilization or the like is performed by high-pressure steam sterilization while the part of the isolation means 1 is held by a holding body from the outside and sealed by resin blocking that occurs at that time.

In the present invention, the actually measured value of the strength of the separating means is not particularly limited as long as it is within a range that a normal person can put on a flat surface and press and release with a palm from above. By way of example, 10~90g / cm ² the isolation means, preferably configured to be released by adding an internal pressure of 20 to 60 g / cm ^2.

A tube 4 is provided and sealed with a plug 3 and a plug 5 respectively. Moreover, the hole 10 for hanging is provided if necessary.

  The thermoplastic resin film used in the infusion container of the present invention is made of linear low-density polyethylene, and the tubular resin sheet is formed by inflation molding, but it is not necessary to be an inflation molded product, Extruded molded products, vacuum molded products, injection molded products, blow molded products and the like may be used.

  The thermoplastic resin in the present invention is not particularly limited, and polyethylene, polypropylene, polyvinyl chloride, ethylene-vinyl acetate copolymer, polyamide, polyvinylidene chloride, polyvinyl fluoride, polytrifluorochloroethylene, polyethylene terephthalate. , Polyester, polyolefin resin, and mixtures and laminates thereof. The infusion container of the present invention is preferably subjected to heat sterilization such as high-pressure steam sterilization or high-frequency sterilization after manufacturing in consideration of hygiene and safety, and a material that can withstand these is preferable.

  A medicine which a doctor or a nurse wants to administer at the same time as the infusion can be put in the empty room of the infusion container of the present invention in advance. As a result, 1) a double bag containing the medicine to be added can be easily prepared (a combination with various kinds of drugs is possible in a hospital without purchasing a double bag for each medicine. 2) It is contained in a bag. When there is a problem in stability when a drug is added to the drug solution, it can be prepared in advance at a nurse center and mixed immediately before use. 3) In a hospital room, mixing can be done more easily by releasing the isolation means, which helps streamline the medical field. 4) It is also useful for home medical care.

  Therefore, by using the infusion container of the present invention, even when other drugs are mixed with medicinal solutions such as electrolyte infusion, amino acid infusion, high calorie infusion and enteral nutrition, they are mixed by a simple operation. And can be safely administered without degradation of the drug.

  The infusion container of the present invention can be used by mixing medicines such as vitamins and antibiotics with electrolytes, amino acid infusions, high-calorie infusions, enteral nutrients, etc. There is no risk of chemical degradation until application.
