Description

[Detailed Description of the Invention] The present invention relates to a package for medical instruments, which includes an outer container having at least one surface made of a transparent plastic material, and a package provided within the outer container for housing the instrument. It consists of an elongated inner envelope, the inner envelope being made of a transparent material and having at least one end closed.

The invention relates in particular to a package suitable for plastic devices such as catheters and cannulas.

Catheters, cannulas, and other medical devices are typically housed in semi-rigid containers with blow-molded plastic fronts, and the containers are occluded with breathable paper.

For containing elongated items such as catheters, a sheet of paper typically forms the longitudinal back wall of the package. With this sheet of paper,
The sealed package and its contents can be sterilized using conventional sterilizing gases.

The blow-molded plastic front is usually transparent, allowing the user to see the contents, and the paper back has a
Contents, manufacturer, and other details are printed.

It may also be desirable to provide an inner package within the outer package. In that case,
The inner package is separate from the outer package to prevent contamination of the contents even after the outer package is opened.

As such a double-layered inner package, an envelope made of low-density polythene has the advantage of being transparent and inexpensive.

Conventional envelopes are sealed along their length and open at one end through which the contents can be removed or sterilized gas can be introduced.

Alternatively, a transverse perforation may be provided midway along the length of the envelope, through which the sterilizing gas can enter, and by pulling the ends along this perforation. , the envelope can be opened by tearing it open.

However, such packages have the disadvantage that the envelope body adheres to the contents when stored for a long time.

It is well known that in conventional envelopes in which the contents are pulled out in the longitudinal direction of the inner envelope, the adhesive force of the envelope makes it difficult to remove the contents.

This problem becomes even more serious when a nurse or the like must place the tip on a surgical trolley without touching the product. In some cases this may not be possible and the envelope body may have to be cut.

For the inner envelope, a material having a similar shape and having a low adhesion to the contents may be used. However, such materials have the drawbacks of being expensive and not having high transparency.

The object of the invention is to provide a package which can overcome the above-mentioned drawbacks.

According to the present invention, there is provided a package of the above type, characterized in that an opening is provided in the longitudinal direction over substantially the entire length of the inner envelope.

This opening is formed by overlapping the longitudinal side edges of the envelope, and the amount of overlapping is approximately 30% of the width of the envelope.

The envelope body may be made of low-density polythene and both ends thereof may be closed. Alternatively, the envelope may be made from a single sheet of material and closed at one or both ends by heat sealing. The other side of the outer container is constructed of breathable paper.

Hereinafter, preferred embodiments of the present invention as a package for a catheter will be described in detail with reference to the accompanying drawings.

In FIGS. 1 and 2, a standard catheter 1 is housed in a double pack 2. In FIGS. This double pack 2 consists of a rectangular outer container 3 and an envelope body 4 housed within this outer container 3.
The catheter 1 is housed in the envelope body 4.

The outer container 3 has the same structure as the conventional one, with a transparent and flexible front surface 3 made of plastic.
0, and a back surface 31 made of paper and having air permeability. Through this back surface 31, sterilizing gas is allowed to enter the interior of the outer container 3, thereby preventing the intrusion of dust and bacteria.

The front face 30 and back face 31 are sealed around their peripheries. One end 32 of these surfaces extends further outward than the sealing portion and serves as an opening tab, so that both surfaces of the outer container 3 can be peeled off there.

As shown in FIG. 3, the envelope body 4 is made of a single rectangular transparent sheet made of low-density polythene.

One end of the envelope body 4 is closed 40, and the other end 41 is open 41.

The envelope body 4 also has an open portion 42 that extends from the open end 41 to the closed end 40. The open portion 42 is formed by the longitudinal edges 43 and 44 of the envelope body 4 overlapping each other by about 30% of the width of the envelope body.

This type of envelope 4 can be easily manufactured by folding the opposite edges of a polythene strip over each other. The folded strip is laterally heat sealed at intervals and one side of the seal is cut laterally to form an open end and a closed end.

In use, the envelope body 4 of the present invention is similar to the conventional one in that it is adhered to the catheter 1, but in terms of removing the tube,
It's much easier than the traditional one.

This is because the envelope body 4 can be opened along its length by simply pulling the edges 43, 44 apart, as shown in the third figure.

In this way, most of the tube is exposed through the opening 42, making it easier to reach into the tube.

Even if there is some adhesive force at the contact portion of the catheter 1 with the envelope body 4, it is easy to separate the envelope body from the catheter.

According to the envelope body 4 according to the present invention, the catheter 1
The force required to peel the envelope 4 away from the catheter or other article along the length of the envelope 4
The force required to separate the envelope body 4 is smaller than that required.

In the present invention, it is sufficient to peel off only one part of the bond between the envelope body 4 and the catheter 1. The reason for this is that as the envelope body 4 is torn off, its adhesive points move.

In comparison, in conventional products of this kind,
The longitudinal adhesive of the envelope body and catheter must be peeled off at the same time.

Within the technical scope of the present invention, in the envelope body 4,
Various modifications can be made.

For example, as shown in FIG.
0,41 is advantageous when the adapter adapter or connector 50 is placed in the outer container 3. When both ends of the envelope are closed in this manner, the adapter is prevented from falling off from the envelope during transportation.

Instead of being formed by overlapping side edges, the longitudinal openings may also abut each other or be separated from each other by longitudinal gaps.

The side edges may also be joined together by breakable welds or members that can be easily torn by the user.

Perforations may be provided in the longitudinal opening of the envelope so that the envelope can be separated along its length.

Note that the closed end of the envelope body does not necessarily need to be airtightly sealed, and it is sufficient that the closed end is closed to the extent that the contents of the envelope body can be retained.

The material used for the envelope may be high density polythene or polypropylene.
