Description

  The present invention relates to an infusion bag for an infusion bag that houses an infusion solution that is susceptible to alteration by light, particularly an infusion bag filled with an infusion solution containing vitamins and amino acids.

  Conventionally, as a material for forming a general infusion bag, a material mainly composed of a resin such as polyethylene, polypropylene, an ethylene-vinyl acetate copolymer, or polyvinyl chloride has been widely used.

The infusion bag is used by being filled with various infusions, and contains infusion solutions that are susceptible to alteration by ultraviolet rays, particularly vitamins (eg, vitamins A, B ₂ , B ₁₂ , K, folic acid, etc.) and amino acids. In the case of infusion, it is necessary to protect the infusion from ultraviolet rays.

  The infusion bag filled with the infusion solution as described above is usually stored in a light-shielding packing material such as cardboard until it is used, so there is almost no risk of exposure to ultraviolet rays. Deterioration due to ultraviolet rays during use, such as drip, becomes a problem.

  Therefore, for example, a method of adding an agent such as an ultraviolet absorber to the material forming the infusion bag to form an infusion bag and absorbing the ultraviolet rays can be considered. In this case, the ultraviolet absorber is eluted in the infusion solution. There is a risk that the safety at the time of infusion (at the time of infusion administration) is significantly impaired.

  In addition, when using an infusion bag, the entire infusion bag is often covered with a cover made of a light-shielding film that completely blocks light. However, since the entire infusion bag is covered during use, There is also a problem that workability is poor because the cover must be lifted and an injection needle or the like must be inserted into the drug discharge port of the infusion bag.

  Therefore, there is a demand for an outer bag for an infusion bag that protects the infusion solution in the infusion bag from ultraviolet rays and has good workability during infusion (during administration of the infusion solution).

  In view of the above problems, an object of the present invention is to provide an outer bag for an infusion bag that protects the infusion solution in the infusion bag from ultraviolet rays and has good workability at the time of infusion (during administration of the infusion solution). .

  As a result of intensive research to solve the above problems, the inventor of the present invention stores an infusion bag in an infusion bag outer bag formed from an ultraviolet blocking film, and in use, the lower part of the outer bag for infusion bag is used. It has been found that the above problem can be solved by providing a lower opening planned portion for exposing only the infusion bag medicine discharge portion to the outside, and the present invention has been completed.

That is, the present invention provides an infusion bag body sealed with a flexible UV blocking film, filled with an infusion solution, protruding from the infusion bag body, and having an outer diameter from the outer periphery of the infusion bag body. An infusion bag for infusion bag in which an infusion bag formed from a small infusion bag medicine discharge section is accommodated, the lower part of the infusion bag outer bag being smaller than the outer periphery of the infusion bag body and discharging the infusion bag medicine A lower opening planned portion having a larger outer diameter than the portion, and the lower opening planned portion is inserted with an infusion bag medicine discharge portion of the infusion bag that is peeled and stored, and only the infusion bag medicine discharge portion is inserted into the infusion bag medicine discharge portion. Provided is an infusion bag outer bag characterized in that it is sealed weaker than at least the peripheral edge of the lower opening planned portion so as to be exposed to the outside of the infusion bag outer bag.
The infusion bag includes a bottle-shaped infusion bottle.

  The outer bag for the infusion bag is formed of an ultraviolet blocking film, so that harmful ultraviolet rays can be blocked, and the lower opening planned portion at the lower part of the outer bag for the infusion bag is only the medicine discharge part of the infusion bag outside. Since it is sealed to a size that can be exposed to be weaker than the peripheral edge of the lower opening planned portion, it can be easily opened during use, and only the medicine discharge portion can be exposed to the outside.

The outer bag for an infusion bag of the present invention can protect the infusion filled in the infusion bag from light of harmful wavelengths such as ultraviolet rays, and can prevent alteration of the infusion.
In addition, the lower part of the infusion bag outer bag of the present invention is provided with a weakly sealed lower opening planned portion for exposing only the infusion bag medicine discharge part to the outside of the infusion bag outer bag. It can be opened, and only the infusion bag medicine discharge part can be exposed to the outside of the outer bag for infusion bag, and the workability at the time of infusion (at the time of infusion administration) is improved.
