Description

[Detailed Description of the Invention] This invention relates to an improvement in packaging for supplying medical instruments to medical institutions after being packaged and gas sterilized.

In order to supply large quantities of medical equipment to medical institutions in a hygienic manner, the medical equipment is individually packaged and sterilized.In order to make it possible to use the medical equipment in a sanitary manner, medical institutions are required to store the supplied medical equipment as needed. It is customary to open the package and use it immediately.

In order to package and sterilize individual medical instruments, as shown in Figure 1, the packaging bag is made of a material that prevents bacteria from entering but allows sterilization and disinfection gas (ethylene oxide gas) to pass therethrough, as well as heat. A nonwoven fabric made of plastic (mainly polyethylene) or paper mixed with polypropylene to be bonded is used as a mount 1. A plastic film 2 that is thermally bonded to the mount 1 is placed on one side of the mount, and a medical instrument 3 is accommodated inside and stacked on the mount. Circumference of plastic film 2 4゜5.6,7
was thermally bonded onto a mount to seal the medical instrument 3.

However, when thermally bonding the mount 1 and the plastic film 2, in order to make it easier to open the package and take out the medical instruments inside, a part 7 of the thermally bonded package is provided with an easy-to-peel part 7, and other parts are separated. Since the part was glued all the way to the side edge 1' of the periphery, when the mount 1 and plastic film 2 were peeled off from the part 7 to be peeled off as shown in Figure 2,
The edge 1' of the mount 1 is prone to breakage, and the breakage causes small fragments to fly off the mount 1. Although the fragments are not unhygienic, the packaging is often opened, especially during surgery. , there is a risk that the packaging may get into the patient's body, and the unsanitary feeling of such pieces of packaging being torn off has been avoided.

In order to improve such deficiencies in conventional medical device packaging, this invention was designed to heat-bond the peeled-off heat-bonded portion of the packaging bag by providing a small non-bonded part on the side edge of the bag. The non-adhesive parts on the side edges of the packaging are difficult to break, so when peeling off the mount and film, only the heat-adhesive parts are torn off, resulting in an excellent packaging with almost no packaging breakage. I was able to do so.

In the embodiment shown in Figures 3 and 4 of the accompanying drawings, the mount 1 of the bag for packaging the medical device 3 is similar to the conventional one as described above, and the mount 1 is strong and does not tear easily. It has a characteristic that does not exist.

The plastic film 2 to be placed on the mount 1 is made of a material that has the property of thermally adhering to the mount 1, or is laminated with another material that has the property of thermally adhering to the mount 1 on the part that is thermally bonded. Preferably, it should be transparent so that the medical instruments 3 housed therein can be seen through.

The periphery of the mount 1 and the film 2 is 4°5, 6. When thermally bonding 7, the medical device 3 is sealed inside, and during bonding, the side edges 1 are particularly attached to the portion where the mount 1 and the film 2 are peeled off, that is, on both side edges.
Non-adhesive parts 4', 6' of a small width are provided from ', 1', and narrow thermal adhesives 4, 6 are applied.

The medical device 3 sealed in the package in this way is immersed in the sterilized disinfectant gas, and the sterilized product is supplied to a medical institution, which opens it when necessary and takes out the medical device 3. In order to open the package, the hot-sealed part at one end of the package is located inward from one end of the bag with enough width to be pinched with your fingertips, so as shown in Figure 4, By pinching the and film 2 with your fingertips and peeling them off, the thermally bonded parts 4 and 6 on both sides of the package are easily peeled off, allowing the medical device 3 to be taken out.

When peeling off, the non-adhesive parts 4' provided on both sides of the package
, 6' are not directly subjected to tensile force, so that only the adhesive portions 4, 6 can be peeled off without the side edges 1' breaking.

Thus, the non-breakage of the side edge 1' is ensured by the mount 1 or the film 2.
This eliminates the risk of the product being torn into small pieces and making packaging safer and more hygienic.
