Description

  The present invention has a steam sterilization treatment for containing a medical product a made of a laminated resin film having excellent barrier properties such as gas barrier properties and ultraviolet cut properties, such as a prefield syringe, a syringe needle pack, and a drug ampoule. The present invention relates to a method for manufacturing a sterilized packaging bag for a medical product with a palm seal type.

  Conventionally, a medical product a such as a pre-field syringe, an injection needle pack or a drug-filled ampoule is made of a non-woven fabric or synthetic paper on a container body 4a made of a relatively hard resin sheet and having a recess formed by a vacuum forming method or the like. A packaging container 4 commonly called a blister pack capable of steam sterilization, covered with a flat lid 4b having air permeability, such as a product, and having front and rear, right and left ends (four sides) sealed seals f 1, f 2, f 3 and f 2 After packaging and steam sterilization with superheated steam, etc., the packaging container 4 containing the medical product a is made of a laminated resin film having various barrier properties such as gas barrier properties and ultraviolet cut properties. For example, a medical sterilization packaging bag shown in FIG. 5 that is double-packaged with a packaging bag 5 of the type is widely used.

However, for the conventional packaging container 4 called the blister pack of the medical sterilization packaging bag shown in FIG. 5, the medical product a is accommodated in the container body 4a formed with a recess by a vacuum forming method or the like. Although it is possible to cover the front and rear left and right ends with a flat lid body 4b having air permeability and to perform steam sterilization treatment with superheated steam as it is,
Various barrier layers such as a ceramic vapor-deposited layer and an ultraviolet absorber layer are provided in order to impart various barrier properties such as gas barrier properties and ultraviolet cut properties to the packaging container 4 commonly referred to as a blister pack containing the medical product a (FIG. Even if the container body 4a in which the recesses are formed by a vacuum forming method or the like using a relatively hard resin sheet in which the container body 4a is laminated, the corners of the recesses formed in the manufactured container body 4a are thinned. Thus, the various barrier layers are destroyed, and after the steam sterilization treatment with superheated steam or the like, the upper surface side of a flat lid body 4b having air permeability such as a nonwoven fabric or a synthetic paper is used. Even if a flat lid (not shown) with excellent barrier properties such as gas barrier properties and UV-blocking properties is placed on the top and bottom and the left and right ends are hermetically sealed, this nonwoven fabric or synthetic paper Lid 4b Thermal fusion of a flat cover member which cover various barrier property and excellent becomes incomplete, it is not completely seal is a problem,
Various barrier properties such as gas barrier properties and ultraviolet cut properties can be imparted to the container body 4a in which the recesses are formed and the air-permeable flat lid body 4b of the packaging container 4 containing the medical product a. Therefore, it was necessary to double-wrap with a packaging bag 5 made of a laminated resin film excellent in various barrier properties such as gas barrier properties and ultraviolet cut properties, such as a palm seal type.

Further, regarding the conventional packaging bag 5 of the above-mentioned sterilization packaging bag for medical products shown in FIG. 5, the blister pack in which the medical product a is accommodated and steam sterilized in the normal bag making process. Although it is a packaging bag 5 that can be easily double-packed, and has various barrier properties such as gas barrier properties and UV-cutting properties,
Even if a vent (not shown) is provided in a part of the packaging bag 5 in order to accommodate the medical product a in the packaging seal 5 such as a palm seal type and perform steam sterilization with superheated steam or the like, After the medical product a is stored and steam sterilized, an appropriate seal (not shown) having various barrier properties such as gas barrier property and ultraviolet cut property is heat-sealed. In spite of the necessity of closing, it is difficult to heat-seal an appropriate seal to the vent hole provided in the packaging bag 5 because the medical product a housed in the packaging bag 5 such as a palm seal type is in the way Is a problem,
Ventilation holes of the packaging bag 5 such as a palm seal type, which has excellent barrier properties such as gas barrier properties and ultraviolet cut properties, which contain this medical product a and are subjected to steam sterilization treatment, inevitably using an adhesive, Steam sterilization treatment is possible because this adhesive or the like may adversely affect the medical product a contained when an appropriate seal with excellent barrier properties such as gas barrier properties and ultraviolet ray blocking properties is attached and closed. Therefore, it is necessary to store the medical product a in the above-described packaging container 4 commonly called a blister pack and to perform steam sterilization with superheated steam in advance.

Furthermore, after storing medical products a such as conventional pre-field syringes, injection needle packs and ampoules containing pharmaceuticals in the packaging container 4 commonly referred to as the blister pack described above, and after steam sterilization with superheated steam or the like, About the sterilization packaging bag for medical products shown in FIG.
In hospitals and clinics where these medical products a are used in large quantities, it is a problem that it takes time to open the packaging container 4 containing the medical products a and the double-wrapped packaging bag 5. The problem is that the manufacturing cost of the packaging container 4 containing the medical product a and the double-wrapped packaging bag 5 is increased by a manufacturer that manufactures the medical product a in large quantities.

  Therefore, an object of the present invention is to accommodate medical products a such as prefield syringes, injection needle packs, and ampoules containing pharmaceuticals, which are made of a laminated resin film having excellent various barrier properties such as gas barrier properties and ultraviolet cut properties. By providing a method for manufacturing a sterilized packaging bag for medical products that can be steam sterilized, the conventional packaging container 4 referred to as a blister pack and a packaging bag 5 such as a cocoon seal type can be used. In other words, avoid double packaging, and greatly reduce the time and effort required for opening in hospitals and clinics and the rise in manufacturing costs at manufacturers.

The method for producing a sterilization packaging bag for medical products according to claim 1 of the present invention is a medical treatment such as a syringe, injection needle or ampoule made of a laminated resin film having various barrier properties such as gas barrier properties and ultraviolet ray blocking properties.
