Description

[Detailed description of the invention] Packaging for sterile items The present invention provides packaging for the purpose of containing one or more sterile article packages. Regarding the body.

For example, this type of packaging for surgical disposable items and wound dressings. The packaging can be fronted in two main styles. Seal the two pieces of paper along the edges. Flat packaging is recommended for thin sterile items such as drying swabs or small surgical pads. Plastic trays sealed with paper lids can be used, for example, in wound dressing sets. Bulky products such as

For packages belonging to any of the above formats, use both hands to pull the package part along the joining line. Tear open to expose the sterile article inside. To maintain the sterility of this item In this case, the article must be removed from the packaging by someone else.

Two or two people are required to do this in order to properly open the package and remove the goods. Ru. After opening the package, for example, you cannot pour out the contents. The reason for this is that when pouring and dispensing, the edges of the non-sterile packaging may touch the contents and contaminate the contents. This is because it loses sterility.

Even when handled correctly, the contents can slide around inside an open package and cause package destruction. Conventional packaging still poses the risk of contamination due to contact with unsterilized edges. be.

In emergencies or when no assistant dressed for sterility is available, someone It is easy to understand that attempting to open the package could jeopardize its sterility. I can understand it.

As is clear from the price tag, traditional packaging requires less personnel to open it. Opening the package is the most inconvenient due to the demands placed on the personnel, while maintaining the packaging while dispensing the contents. Sufficient safety regarding the sterility of the contents cannot be guaranteed.

Therefore, the purpose of the present invention is to maintain the sterility of the contents while making it easy to open, and only one person can open it. To achieve a sterile article packaging whose contents can be taken out by opening it with a finger.

Therefore, by choosing a suitable material for this packaging or by other means, the price requirements can be met. A package for sterile goods that satisfies the above-mentioned contents in a sealed state The inner surface of at least some portion of a package that can be torn open to remove an item By selecting the materials for the layers, the inner layer and the corresponding outer layer can be created. A degree of hand tension is applied, and this hand tension is applied before the tensioned material is rolled up. Open the package so that the sterile inner surface is exposed and the non-sterile outer surface is hidden. This has been achieved by the present invention in that it can be removed by

Pre-stretching the packaging material has a wide range of alternative possibilities. You can choose from the law.

For example, two outer material layers may be attached to each other to varying degrees to create a tensile difference between them. Manual tension is applied from the beginning to a material made into a laminate consisting of pre-tensioned layers. You can

The above also applies to the materials of the layers included in the laminate with different coefficients of thermal expansion. A tensile difference is obtained.

Hand tensioning can also be achieved by purely mechanical means such as wire, plastic springs, etc. can.

The invention will be described in more detail below with reference to embodiments illustrated in the accompanying drawings.

Brief description of the drawing Figure 1 is a cross-sectional view of the package of the first embodiment of the present invention, and Figure 2 is an open view of the package of Figure 1. Figure 3 is a cross-sectional view of the package according to the second embodiment of the present invention. 4 is a cross-sectional view showing the package shown in FIG. 3 in an open state, and FIG. 5 is a sectional view. A perspective view of the third embodiment; FIG. 6 is a perspective view of the package shown in FIG. 5 when it is opened; The figure is a perspective view of another embodiment of the present invention, and Figure 8 is the package shown in Figure 7 when opened. It is a perspective view of a body.

The package shown in Figure 1 consists of an upper part 1 and a lower part 2, which are connected to their edges. The sterile articles 3 are housed by being connected to each other along these lines. Each part of this package Coupling can be done in different ways. For example, along the long side of the package This method involves melting and sealing the short sides by heat.

The material of the package part is finished and the tension of the sealed package is applied to the inner surface of the package part. Since the two-handed stress is given to be much higher in the outer layer than in the outer layer, The package tends to shrink along this outer layer. When the package is sealed , the prestress force is absorbed by the bond between the wrapper parts, so that these wrapper parts This force is released after the package is opened in the conventional way by tearing and removing the The candy can be rolled up and parts 1 and 2 are rolled up as shown in FIG. do that The sterile item is exposed, but the outer surface of the package, which is no longer sterile due to hand contact, is exposed to the contents. It rolls away from the body and rolls inward, exposing the sterile inner surface at the same time. Parts 1 and 2 are rolled up The contents are then removed from the package by dropping the contents onto a sterile surface intended for this purpose. It can be easily emptied from Contrary to what is possible with conventional packaging, the packaging of the present invention The entire procedure of opening and removing the contents can be done by one person without risk of contaminating the contents. This is a big advantage.

Figure 3 shows that the lower part 2 of the package is made of pre-tensioned material and the upper part 1 is made of pre-tensioned material. A second embodiment is shown made of conventional packaging material such as varnish-soaked insulating paper. upper part l has two parts 5.6 joined at sea/L/4. The package is a sterile article 3. The article 3 is sealed by tearing off one of the parts 5 of the upper part 1. exposed when the package is opened.

Figure 4 shows how to roll up the back of the package to sterilize the contents as shown in Figure 3. Indicates whether to remove the item. In this example, sterile articles are also dropped onto a sterile surface and packaged. The risk of contaminating the sterile article during removal from the body is completely avoided. There is no reason for that All parts that may come into contact with the germ article are located on the edge surface of the remaining part 6 of the upper part 1. This is because surfaces, including surfaces, remain sterile.

FIG. 5 shows another embodiment that is particularly useful for containing bulky items.

The package shown in FIG. 5 has a dish-shaped lower part 2 and flat rectangular side parts 1, The upper part 1 has four triangular parts 7 delimited by the diagonals and edges of this part. Consists of 10.

The triangular parts are joined by two intersecting tape strips 11.12, so that The resulting rectangular lid 1 is joined to the lower part 2 along its edge. The body can be opened by tearing off the tape strip 11.12. , the triangular part, which has been pre-tensioned as shown in the example above, is wound as shown in Figure 6. Rise up and become one. The edges of the triangular portion on the underside of the tape strip are sterile The sterile article 3 will not be contaminated.

One advantage of this packaging is that it must be soaked in a sterile liquid, e.g. salt water, before use. It can be used as a container for disinfectant cotton or pads. In this case It can be poured directly onto the pad or swab inside the container. damage these items When using it for treatment, remove each sterile swab soaked in liquid from the package. There is no risk of touching non-sterile surfaces of the packaging.

FIG. 7 shows a further embodiment of the invention, similar to the embodiment described above, with a dish-shaped lower part 2 and a flat surface. It has a lid 1. The lid 1 has a lower part 2 (which is sealed with a tape strip 13). Ru. The package can be removed by tearing off the tape strip 13 as shown in FIG. When opened, the lid 1, which has been given tension in advance, rolls up. In this way, sterile Item 3 is ready for pressure use. The plate part is covered with dezo during sterilization process. The entire edge 14 of the dish portion thus remains sterile. In the embodiment of FIGS. 5 and 6 Similarly, this package is also particularly useful for bulky items and for dressing wounds. It can also be used, for example, as a container for moist pads.

Although the above description did not mention how to achieve manual tension, for example, The packaging part that rises and becomes one piece looks like one outer layer has been manually stressed. It can be formed from a laminate stacked on one or more stress relief layers.

Another method of prestressing is wrapping an elastic band with one or more hand-tensioned This is a method in which the adhesive is attached to the side of the material that constitutes the outer surface of the package.

Hand-stretching can also be achieved by selecting materials with stress development gradients during manufacturing. You can also

Alternatively, there is an alternative method, such as incorporating hand tension into the material from the beginning. Finished packaging made from tobacco materials can also be activated by heat treatment. Ru.

All of the following packages provide a detailed explanation of the invention without limiting the scope of the invention. This invention is described by way of example for the sole purpose of are contemplated within the scope of the claims of the invention. For example, the physical form or use of the packaging. There are no restrictions on the type of materials.
