Description

[Detailed explanation of the idea]

[Industrial Application Field] The present invention relates to a medical sterilization bag. More specifically, the present invention relates to a sterilization bag used for transporting and storing sterilized medical tools without exposing them to bacteria. [Prior Art] A conventional medical sterilization bag will be explained based on FIGS. 10a to 10d. This medical sterilization bag uses an inner bag 30 and an outer bag 40. The inner bag 30 is made of a non-breathable film, and a ventilation portion 31 is provided in a part thereof. Further, the outer bag 40 is made only of non-breathable film and is provided with gas barrier properties. To enclose the medical device a, first put it into the inner bag 30, and then seal the upper edge 32 by heat sealing or the like (FIG. 7b). Then, the inner bag 30 is sterilized and placed in the outer bag 40 (Fig. 7c). At this time, an air conditioner b such as a degassing agent is also added. Finally, the upper edge 41 of the outer bag 40 is sealed (Fig. 7b). As mentioned above, conventional sterilization bags are double wrapped. [Problems that the invention aims to solve] In the case of conventional double-wrapped sterilization bags, two packaging materials are required, which increases production costs and requires a lot of effort to enclose medical devices. There is. In view of these circumstances, the present invention aims to provide a sterile bag that is low in production cost and requires little effort to seal. [Means for Solving the Problems] The medical sterilization bag of the present invention includes a packaging bag sealed with a non-breathable film, a first compartment for storing sterilized medical tools inside the packaging bag, and a first compartment for storing sterilized medical tools. and a second compartment for containing an adjacent air conditioning agent, and at least a part of the diaphragm is made of a film that is breathable and impermeable to bacteria. [Operation] After inserting the medical device into the first compartment of the sterile bag,
Sterilization is performed by sealing only the opening on the first compartment side. After the sterilization process, an air conditioner is further inserted into the second compartment and the opening on the second compartment side is sealed. If transported or stored in that condition,
The air in the compartment passes through a breathable diaphragm into the second compartment.
As it diffuses towards the compartment, the air within the first compartment is conditioned. [Example] Next, an example of the present invention will be described. Fig. 1 is a partially cutaway perspective view of a sterilization bag according to an embodiment of the present invention, Fig. 2 is an external view of the sterilization bag shown in Fig. 1, and Fig. 3 is ()-- in Fig. 2.

Figures 9 to 8 are perspective views showing other configuration examples of the diaphragm 2.
Figures a to 9b are explanatory diagrams of a medical device enclosing operation. In Figs. 1 to 4, 1 is a packaging bag and 2 is a diaphragm. The packaging bag 1 is a bag-like container whose periphery is sealed, and is made of a non-breathable film. The non-breathable film used here is preferably a laminate film of aluminum or polyester and polyethylene or polypropylene.
Note that the film referred to herein includes not only so-called films but also sheets. A diaphragm 2 is sandwiched between the front side film 1a and the back side film 1b of the packaging bag 1.
It is divided into a drawing room 3 and an adjacent second drawing room 4. The diaphragm 2 is made of a film that is at least partially breathable and impermeable to bacteria (hereinafter simply referred to as a breathable film), and nonwoven fabric, cloth, paper, etc. are used as the film material. In the case of paper, filter paper is preferred.
The diaphragm 2 has the same vertical and horizontal dimensions as the packaging bag 1, or is preferably made slightly smaller than that (if it has the same dimensions as the packaging bag, the gas impermeability is slightly inferior), and the surface side It is sandwiched between the film 1a and the back side film 1b and joined by means such as heat fusion. As shown in FIGS. 3 and 4, the four-circumference seal portion 5 joined in this manner includes an outer peripheral seal portion 6 in which the front side film 1a and the back side film 1b are joined in two layers, and A three-layer inner peripheral seal portion 7 is formed with the diaphragm 2 sandwiched therebetween. Since the outer peripheral seal part 6 blocks the air-permeable diaphragm 2 from the outside air, it guarantees the airtightness of the packaging bag 1. Further, the inner peripheral seal portion 7 functions to fix the diaphragm 2 inside the packaging bag 1.
As described above, the packaging bag 1 may have two front side films 1a and a back side film 1b attached to each other, but as shown in FIG. 8, and then the seal portion 5 may be formed by heat fusion or the like. The diaphragm 2 may be made entirely of a film having air permeability, or may be made of a film 2a having only a part thereof as shown in FIGS. 7 and 8. In this case, the shape of the ventilation portion may be circular, band-like, or various other shapes. The other portion 2b of the diaphragm 2 may be made of a non-breathable film or a normal film. The sterilization bag of this example has medical tools a in the first compartment 3.
is introduced into the second compartment 4, and the air conditioner b is introduced into the second compartment 4. Note that the first compartment 3 and the second compartment 4 are names added for convenience, and either compartment may become the first compartment 3 or the second compartment 4. When enclosing the medical device a and the air conditioner b into the first compartment 3 and the second compartment 4, as shown in FIG. 9, the sterilization bag is sealed on three sides, while, for example, the upper edge is not sealed. It is opened and sealed after being enclosed. The procedure will be explained based on FIGS. 9a to 9d. First, medical equipment a is placed in the first room 3.
(Fig. 9a) and seal only one side (5a) of its upper edge (Fig. 9b). Next, the sterilized bag is sterilized. The sterilization work here is as follows:
EOG sterilization (ethylene oxide gas sterilization, the same applies hereinafter), radiation sterilization, high pressure steam sterilization, etc. are used. Next, put the air conditioner b into the second compartment 4 (Fig. 9c), and apply the other side (5b) of the upper edge to the one side (5a).
(Figure 9d). Through the above steps, sterilization and packaging of the medical device a are completed. In the above process, various types of air conditioning agent b can be used to fill the second compartment 4, but in the case of EOG sterilization, a moisture absorbent, a degassing agent (for example, activated carbon, etc.), or an oxygen absorbing agent can be used. etc. are used. When radiation sterilization is performed, oxygen absorbers and deodorizers are used. Furthermore, when high-pressure steam sterilization is performed, oxygen scavengers and moisture absorbers are used. Note that the air conditioning agents b listed above are all typical ones, and in addition to these, various other agents can be used as necessary. Since the sterilized bag that has been filled as described above is isolated from the outside air, bacteria will not adhere to the sterilized medical device a. Furthermore, since the medical device a and the air conditioning agent b coexist inside the device via the breathable diaphragm 2, air treatment after sterilization is continuously performed. Next, the advantages achieved by various air conditioning agents b are shown in Tables 1 to 3 below.
