The composite film is a bag for preventing contamination of the container, especially when the IVH of the contents is easily oxidized.
It is preferable to have a barrier layer made of a polyvinylidene chloride or saponified enylene vinyl acetate copolymer between the seal layer and the outer layer.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The bag material used in the present invention is a composite film having at least one layer uniaxially stretched and comprising at least a sealing layer and an outer layer and having light-shielding properties. The sealing layer must be capable of heat sealing when the bag is made, and specifically, linear low density polyethylene (L-LDPE), low density polyethylene (LDP)
E), high-density polyethylene (HDPE), polypropylene (PP), enylene vinyl acetate copolymer (EVA) or a mixture thereof is used, and if there is no intermediate layer, it must be uniaxially stretched. The thickness of the sealing layer is 5
50 μm is required.

The outer layer is required to have strength as a bag and heat resistance such as being not melted by radiation sterilization or heat sealing temperature. For example, stretched nylon (ONy) which is biaxially stretched and heat-set and hardly thermally shrinks, stretched Polypropylene (OPP) or expanded polyethylene terephthalate (O-
PET). The thickness of the outer layer is 8 to 30 μm, preferably 10 to 20 μm.

The intermediate layer is necessary especially when the sealing layer is difficult to uniaxially stretch, and must be uniaxially stretched. Uniaxial stretching is the same when provided not only in the intermediate layer but also in the seal layer, but when used as a bag, it is necessary to be able to easily tear from the notch, and the film is stretched in the bag tearing direction, That is, it must be in the horizontal direction (in the drawing). When the seal layer and the intermediate layer are co-extruded, both may be uniaxially stretched. As a material of the intermediate layer, polypropylene, polyethylene terephthalate or various nylons can be used.

The barrier layer is necessary particularly when the IVH or the like is liable to be oxidized, and a saponified enylene vinyl acetate copolymer film is provided between the sealing layer and the outer layer. Between or between the intermediate layer and the outer layer, by using a dry lamination or the like,
It is used by coating polyvinylidin chloride on the inside of the intermediate layer or the outer layer.

The IVH or the like requires a light-shielding property in order to prevent deterioration due to ultraviolet rays or the like, and is provided by coating a light-shielding ink on the entire inner surface of the outer layer. The composite film used in the present invention needs to be transparent enough to read the scale and characters of the drip packaging container, and therefore needs to have the same degree of transparency when coated with a light-shielding ink.

The present invention will be described in detail with reference to the drawings. The contamination prevention bag 23 used in the present invention is a bag in which the three sides including the upper heat-seal portion 1 and the side seal portions 7 on both sides are heat-sealed. The hook take-out part 2 of the part is a take-out opening of the hook part 6 of the drip wrapping container A, and the lower part of the bag is not heat-sealed and serves as an insertion opening 3 into which the drip wrapping container A is inserted. An upper V-notch 4 is provided in the side seal portion 7 at a position slightly lower than the upper portion of the hook outlet of the drip packaging container, and a lower heat seal for vacuum sealing after inserting the drip packaging container into the bag. A lower V-notch 5 is provided in the side seal portion 7 slightly above the position of the portion 8, and the bag is sterilized by radiation. Normally, gamma rays or electron beams are used as the radiation.

Next, a method of using the pollution control bag of the present invention will be described. The drip wrapping container A having the chemical liquid inlet 9 and the chemical liquid outlet 10 as shown in FIG. 7 and having the chemical liquid mixed therein is inserted into the contamination prevention bag 23 shown in FIG. As shown in FIG. 7 through the opening 3, the inside of the contamination prevention bag is evacuated by suction from the insertion opening 3, and the lower heat seal portion 8 of the insertion opening is vacuum-sealed as shown in FIG. save. When injecting a drug solution or the like into a patient, as shown in FIG. 9, the contamination prevention bag is torn laterally from the upper V notch 4, the hook portion take-out portion 2 is opened, the hook portion 6 is pulled out, and the hanger 11 is pulled out. Then, the contamination prevention bag is torn laterally from the lower V-notch 5, and a drip tube 12 is connected to the chemical solution outlet 10 as shown in FIG. Further, in the case of the drip wrapping container A in which the hook portion does not protrude, the both ends of the hook portion take-out portion can be cut open with scissors or the like as shown in FIG. In these cases, the width dimension of the hook take-out portion must be smaller than the width dimension of the drip packaging container.

[0012]

By using the contamination prevention bag of the present invention, it is possible to prevent the contents of IV drip and the like for IVH and the like from being deteriorated due to oxidation or the like under reduced pressure, and to provide a light-shielding composite before the IV drip is performed. Since a bag made of film is used, it is possible to instill the drug such as vitamin E and vitamin A mixed in the drug solution to the end without injuring the drug when instilling the patient. Further, since the contamination prevention bag has transparency so that the patient can see the state of the liquid medicine for infusion from the outside at the time of infusion, mental stability can be obtained.
In addition, it is possible to pack both the effects of a hospital infection prevention bag and a light-shielding bag for preventing quality change such as IVH in the same bag.
