Benefits of technology

The present invention is a packaging bag for medical supplies that allows visual confirmation of the content without bleaching the medical supplies. The packaging bag is made of a bacteria impermeable film and a gas permeable film, and the medical supplies are sterilized using a sterilizing gas such as ethylene oxide gas or the like. The packaging bag is designed to prevent the sterilizing gas from entering the inner bag and bleaching the medical supplies. The technical effect of the invention is to provide a packaging solution for medical supplies that allows for visual confirmation of the contents without compromising the quality of the medical supplies.

Problems solved by technology

The medical supplies are manufactured and contained in a packaging bag until use, which is not a constant period but storage is often a long time as well.
Moreover, disinfection is conducted using sodium hypochlorite, hydrogen peroxide, and the like in hospitals, and these disinfectants may penetrate into the packaging bag.

working example 1

[0045]Table 1 shows results from an experiment using four types of packaging bags A, B, C, and D. In Table 1, thickness (μm) is thicknesses of the films 11 and 12 constituting the packaging bag 10 for medical supplies, where 50+80 denotes that thickness of the film 11 is 50 micrometers and that of the other film 12 is 80 micrometers. Both of these films have used a film on which silica is deposited on each side.

Abstract

There are provided a packaging bag, which allows visual confirmation of the content yet does not bleach medical supplies contained therein, a packaging bag containing medical supplies, and a packaging method for medical supplies.A packaging bag 10 of the present invention includes two front and back films 11 and 12, at least one of which is transparent and are bacteria impermeable and do not transmit molecules as large as or greater than O2, wherein a material 13 that is gas permeable and bacteria impermeable is extended on the opening side of at least one of the films, and the periphery of the front and back films except for the opening is sealed. Medical supplies 15 are contained in the packaging bag 10, the opening is sealed to form a seal part 16b, and sterilization processing using EO gas or the like is executed. The EO gas is then removed and it is sealed by a seal part 16c. Even if the medical supplies 15 are exposed to an antiseptic solution such as H2O2, it will not enter the packaging bag 10.

Description

TECHNICAL FIELD[0001]The present invention relates to a packaging bag. More specifically, it relates to a packaging bag containing various medical supplies such as suture needles, suture thread, and a packaging method.BACKGROUND ART[0002]The medical supplies such as surgical suture thread and suture needles are contained in a packaging bag after production, and are sterilized and then stored. When using, the packaging bag is opened and the medical supplies are taken out and then used.[0003]The medical supplies are manufactured and contained in a packaging bag until use, which is not a constant period but storage is often a long time as well. Therefore, the sterilized state needs to be maintained throughout the storage period. A bacteria impermeable film is used for the packaging bag for this purpose.[0004]Moreover, disinfection is conducted using sodium hypochlorite, hydrogen peroxide, and the like in hospitals, and these disinfectants may penetrate into the packaging bag. Since the...
