[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a packaging bag suitable for radiation sterilization, and more particularly to a packaging bag for a blood processing device in which an oxygen scavenger is contained and fixed.

[0002]

[Prior art]

 Recently, as a sterilization method for disposable medical devices, sterilization by radiation, especially gamma rays, is becoming popular.However, since most of the constituent materials of disposable medical devices are plastic, the plastic is deteriorated by irradiation of radiation. As a result, medical equipment may become defective and may generate an odor, which was a problem.

As a solution to this problem, a method of sealing an oxygen scavenger in a gas-impermeable packaging bag together with the hollow fiber type blood treatment device when irradiating the hollow fiber type blood treatment device with radiation (Patent Publication 5) No. 50946) is known. That is, even if the oxygen scavenger is stored together with the hollow fiber blood processor in a gas-impermeable packaging bag, the activity of the oxygen scavenger is not lost even when the radiation is applied, and the hollow fiber blood processor is degraded It has been found that problems such as the occurrence of toxicity and toxicity do not occur.

[0004]

[Problems to be solved by the device]

 However, in this method, the oxygen absorber is only stored in the packaging bag without being fixed, so when the packaging bag is opened, the oxygen absorber falls to the floor and is unsanitarily picked up. . If the oxygen absorber is present near the cut edge when the packaging bag is opened, the oxygen absorber package will be torn when the packaging bag is opened, and the active metals and other substances in the package will adhere to the blood treatment device and scatter on the floor. Or

[0005]

[Means for Solving the Problems]

 The present invention is intended to solve the above-mentioned problems, and is made of a gas impermeable material, and an oxygen scavenger is fixed in a position outside the cutting site in the packaging bag. It is a packaging bag. The present invention is also a packaging bag for a blood processing device, wherein a part of the oxygen absorber packaging body in the packaging bag is fixed by a seal portion at an end of the packaging bag.

[0006]

[Embodiment of device]

 The packaging bag of the blood processor obtained by the present invention will be described. FIG. 1 is a plan view of a packaging bag 12 accommodating a blood treatment device 11 according to an embodiment of the present invention, in which the blood treatment device 11 is accommodated in a gas impermeable packaging bag 12, The oxygen agent 13 is fixed to the seal portion 15 at a position separated from the cut portion of the packaging bag 12. In addition, the seal portion 14 of the packaging bag 12 is formed with a cut end 16 as a slitting start point for slitting the packaging bag 12.

In FIG. 1, the oxygen scavenger 13 is fixed to the seal portion 15 in the packaging bag 12, but the position for fixing the oxygen scavenger is not particularly limited as long as it is a position apart from the cut site. .. Examples of methods for fixing the oxygen absorber include a method of sealing with a heat sealer, a method of adhering with an adhesive tape such as a double-sided tape, a method of adhering with an adhesive, and the like. Particularly, in consideration of cost and simplification of manufacturing process, a method of sealing the end of the oxygen absorber package with a heat sealer at the same time as sealing the packaging bag is preferable.

Examples of the blood treatment device include a hollow fiber type dialyzer, a coil type dialyzer, a flat plate type dialyzer, a hemofilter, a blood adsorber and the like.

As the packaging bag for the blood treatment device, a gas-impermeable bag is preferable in order to prevent the invasion of oxygen from the outside and improve the effect retention of the oxygen scavenger. Examples of gas impermeable materials include unstretched or stretched films or sheets of polyvinylidene chloride, polyvinyl alcohol, polyamide, polyester, etc., films or sheets coated with these resins, or films laminated with these films or Sheet, polyester / aluminum / polyethylene laminate film or sheet, polyethylene terephthalate / polyethylene / aluminum / polyethylene or nylon / polyethylene / aluminum / polyethylene 4-layer laminate film, aluminum foil, aluminum vapor deposition film And metal foils, metal vapor deposition films, or laminated products thereof. In particular, a laminated film having a four-layer structure of polyethylene terephthalate / polyethylene / aluminum / polyethylene or nylon / polyethylene / aluminum / polyethylene is preferable.

The oxygen scavenger contained in the packaging bag of the blood treatment device generates a gas component (hydrogen, carbon dioxide gas, etc.) when absorbing oxygen, generates a gas component by irradiation of radiation, or is an oxygen scavenger. It is preferable that it is non-toxic and does not lose its activity. For example, it is preferable that the oxygen scavenger contains an active metal as a main component and the reaction rate thereof is controlled by a catalyst, and examples of the active metal include iron, zinc, copper and tin. Particularly, those containing active iron oxide as a main component are preferable. As a commercially available product, there is Ageless (trade name of oxygen absorber manufactured by Mitsubishi Gas Chemical Co., Inc.).

FIG. 2 is a cross-sectional view of the packaging bag 12 of FIG. 1 taken along the line AA ′, in which the blood treatment device 11 is housed in the gas-impermeable packaging bag 12 to remove oxygen. The agent 13 is fixed to the seal portion 15 at a position separated from the cut portion of the packaging bag 12.

FIG. 3 is a plan view of a packaging bag 32 accommodating a gas permeable bag 37 accommodating a blood processor 31 according to another embodiment of the present invention. A gas-permeable bag 37 is housed in a gas-impermeable packaging bag 32, and an oxygen scavenger 33 is fixed to a seal portion 35 at a position outside the cut portion of the packaging bag 32. Further, the sealing portion 34 of the packaging bag 32 is formed with a cut end 36 as a slitting start point for slitting the packaging bag 32.

The gas permeable bag is used as the bag for accommodating the blood treatment device. When the gas impermeable bag is used, oxygen in the micropores of the semipermeable membrane of the blood treatment device is gradually released. As a result, it was confirmed that oxygen was accumulated in the bag, and the decrease in strength of the blood treatment device with time progressed at high temperatures. As a gas permeable bag, along the both edges of the gas impermeable laminate film consisting of the polyethylene terephthalate layer and the polyethylene layer, the widthwise both edges of the tape made of the gas permeable polyethylene spunbonded nonwoven fabric Is preferably a bag obtained by heat-sealing the polyethylene layer of the laminate film to form a cylindrical shape, and then heat-sealing both ends of the opening to close the bag.

FIG. 4 is a cross-sectional view of the packaging bag 32 of FIG. 3 taken along the line BB ′, in which the gas permeable bag 37 accommodating the blood processing device 31 is a gas impermeable packaging bag 32. The oxygen absorber 33 is housed inside, and is fixed to the seal portion 35 at a position outside the cut portion of the packaging bag 32.

FIG. 5 is a partially cutaway perspective view of the packaging body 52 containing the oxygen scavenger 51 therein. In the packaging body 52 containing the oxygen scavenger 51, a seal portion 53 is provided at the end of the packaging body 52. Are formed. In the packaging bag accommodating the blood treatment device shown in FIGS. 1 to 4, the sealing portion 53 of the packaging body 52 is heat-sealed and fixed to the sealing portion 15 or 35 of the gas-impermeable packaging bag.
