The present invention relates to, for example, a flexible container for accommodating a medical device having a puncture needle.

When doctors, nurses, etc. visit patients at home to perform medical treatment (during home visit medical treatment), medical equipment such as syringes used for treatment is stored in a medical waste container. For example, the medical waste container disclosed in Patent Document 1 is provided with a box-shaped main body and a needle puncture body for puncturing a sharp portion of an injection needle used in the main body, so that it takes time and effort to recap the needle. And prevent accidental needle sticks.

Japanese Unexamined Patent Publication No. 2014-176445

However, the box-shaped main body as disclosed in Patent Document 1 is formed rigidly so as not to apply an external force to the medical device. Therefore, it is bulky and easily takes up a large space, and when carrying a medical waste container in a home-visit bag, a lot of labor is required, such as devising a method of packing other equipment.

Here, it is also conceivable that the main body of the medical waste container has a flexible configuration (flexible container). However, in the case of simply using a flexible container, even if the injection needle is stuck in the needle stick, the injection needle changes its posture or the injection needle is pushed due to the bending or external force of the container. Therefore, in some cases, the injection needle may break through the container, resulting in erroneous puncture or the like.

The present invention has been made in view of the above circumstances, and is portable by firmly preventing exposure of a medical device or the like having a puncture needle and making it freely deformable with appropriate flexibility. An object of the present invention is to provide a flexible container that is easy to use and has good usability.

In order to achieve the above object, the flexible container according to the present invention is a flexible container for accommodating a medical device having a puncture needle, and is laminated on the flexible bag body and the bag body. , and a metal fiber layer configured to have aggregated and flexible a plurality of metal lines, each line size of the plurality of metal lines Ri 0.1mm~0.2mm der, said metal fibers The layer includes a mesh-like sheet formed by weaving the plurality of metal wires in a plain weave or a twill weave, and the metal fiber layer has a number of stitches between the plurality of metal wires of 30 mesh to 100 per inch. It is characterized by being in the range of the mesh.

According to the above, the flexible container has a metal fiber layer composed of a metal wire having a wire diameter of 0.1 mm to 0.2 mm, so that the metal wire can be prevented from breaking even if an external force is applied to the puncture needle. Can be done. Therefore, even if the puncture needle is discarded in the container without being recapped, the exposure of the puncture needle can be strongly prevented. Further, since the metal fiber layer of the flexible container is flexible, the shape of the flexible container can be freely deformed according to the form of use, and the flexible container can be easily carried, so that good usability can be obtained.

By providing the metal fiber layer of the mesh-like sheet woven by plain weave or twill weave, the flexible container can be easily manufactured and the manufacturing cost of the flexible container can be reduced.

The flexible container is provided with a metal fiber layer having a number of meshes set to 30 mesh to 100 mesh, so that the medical device can be kept flexible while not exposing the medical device.

Alternatively, the metal fiber layer may include a non-woven sheet in which the plurality of metal wires are irregularly arranged and points where the metal wires overlap each other are point-fused.

The flexible container can be provided with a metal fiber layer of a non-woven sheet to obtain sufficient flexibility. Moreover, since the non-woven sheet is point-fused at the points where the metal wires overlap each other, it is possible to suppress the separation of the metal wires and prevent the medical device from sticking out.

Further, the metal fiber layer may be formed in a plurality of layers with respect to the bag body.

Since the flexible container is provided with a plurality of metal fiber layers, it is possible to more reliably prevent the exposure of the medical device. Moreover, the plurality of layers can be easily formed by folding or stacking the metal fiber sheets, and the manufacturing cost can be suppressed.

Further, in the metal fiber layer, it is preferable that the opening ratio of the eyes between the plurality of metal wires is in the range of 20% to 50%.

The flexible container is provided with a metal fiber layer having an opening ratio of 20% to 50%, so that the medical device can be kept flexible while not exposing the medical device.

The metal wire may be made of a stainless steel material.

In the flexible container, since the metal fiber layer is made of a metal wire made of stainless steel, it is possible to form a metal fiber layer having an appropriate hardness that is plastically deformable and is not broken by a medical device.

Furthermore, it is preferable that the bag body has a chuck portion that can be opened and closed, and the metal fiber layer is provided on the entire inner surface of the bag body on the back side of the chuck portion.

By providing the metal fiber layer on the entire inner surface of the bag body, the flexible container can prevent the medical device from slipping through the metal fiber layer and being exposed.

It is a table which shows the experimental result of the flexible container which concerns on this invention.

Hereinafter, suitable embodiments of the flexible container according to the present invention will be given, and will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1A, the flexible container 10 according to an embodiment of the present invention is a medical device (as shown in FIG. 1A) that is possessed by a user such as a doctor or a nurse when visiting a patient at home and used in home visit medical care. It is a medical waste container that stores waste) (hereinafter, also simply referred to as container 10). Examples of the medical device to be discarded in the container 10 include a syringe having a puncture needle, a winged needle, and a glass ampoule which may be damaged and debris may be scattered.

The container 10 is configured to prevent the puncture needle from breaking through the container 10 even if the puncture needle is housed without being recapped at the time of disposal. Further, the container 10 has sufficient flexibility so that it can be deformed as needed, and is configured to be easily accommodated in a user's home visit bag (not shown). Hereinafter, the container 10 will be specifically described.

As shown in FIGS. 1A and 1B, the container 10 according to the present embodiment includes a flexible bag body 12 and a metal fiber layer 20 laminated on the bag body 12. The container 10 may be appropriately designed so that a size that can accommodate a medical device and a size that is easy to carry (easy to fit in a home visit bag) can be compatible with each other. The size of the container 10 depends on the object to be accommodated, but is preferably, for example, a height of about 80 mm to 200 mm and a width of about 80 mm to 200 mm. The container 10 according to the present embodiment has a height of 110 mm and a width of 110 mm.

The bag body 12 according to the present embodiment is configured as a bottom gusset type having a gusset portion 16 at the bottom. Therefore, the container 10 can have a thin sheet shape by folding the gusset portion 16 in a state where the medical device is not accommodated. Further, the container 10 can be deformed into a so-called stand type in which the bottom portion (gusset portion 16) is expanded by the user so that the container 10 can be independently placed on a flat place when the medical device is disposed of. Is.

The bag body 12 has a pair of film-shaped (or sheet-shaped) side surface portions 14 and a gusset portion 16, and is formed into a predetermined shape by heat-sealing the peripheral portions thereof. Specifically, the bag body 12 includes a side seal portion 18 that seals both ends of the pair of side surface portions 14 with the gusset portion 16 folded, and a peripheral portion of the gusset portion 16 that is folded back from the pair of side surface portions 14. It has a bottom seal portion 19 that seals the pair of side surface portions 14. By forming the entire peripheral portion of the gusset portion 16 harder than the other portions at the bottom seal portion 19, the independence of the container 10 is sufficiently ensured.

An internal space 11 having a predetermined volume is formed inside the container 10 (bag body 12) in which the gusset portion 16 is expanded. The volume of the internal space 11 changes according to the shape of the container 10. Further, the container 10 has an opening 11a in an upper portion (a portion opposite to the gusset portion 16) that allows the internal space 11 to communicate with the outside of the container 10. A chuck portion 30 for sealing the internal space 11 is provided on the pair of side surface portions 14 constituting the opening portion 11a.

The chuck portion 30 is fixed to the inner surface of the pair of side surface portions 14 by an appropriate fixing means, and a structure capable of repeatedly closing and opening the internal space 11 is applied under the operation of the user. The configuration of this type of chuck portion 30 is not particularly limited, and for example, the convex portion 30b fixed to the other side surface portion 14 is inserted and engaged with the concave portion 30a fixed to the one side surface portion 14. , The one that closes the opening 11a.

The material constituting the bag body 12 is not particularly limited, but a resin film having a function of shielding a liquid may be applied. Examples of this type of material include resin films such as polyethylene, polypropylene, polyolefin, polyethylene terephthalate, polyvinyl chloride, and nylon. With such a material, leakage of body fluid or chemical solution from the bag body 12 can be suppressed. Aluminum may be vapor-deposited or laminated on the resin film. As a result, the bag body 12 can be prevented from being visually recognized from the outside so that the discarded medical equipment, body fluid, chemical solution, and the like cannot be seen. Moreover, these materials may have heat resistance. As a result, the container 10 containing the discarded medical equipment can be heat sterilized without being damaged even if it is placed in the high-pressure steam sterilizer (autoclave) as it is, and the infectivity of infectious substances such as body fluids can be suppressed. Can be done.

On the other hand, the metal fiber layer 20 has a function of preventing a medical device such as a puncture needle placed in the container 10 from penetrating from the container 10. Further, the metal fiber layer 20 according to the present embodiment is configured to have flexibility so that the shape can be deformed integrally with the bag body 12.

The metal fiber layer 20 is formed by aggregating a plurality of metal wires 22 into a sheet shape. Here, the agglutination of the plurality of metal wires 22 means that the metal wires 22 are closely overlapped, aligned, intersecting, or intertwined with each other while having a gap between the metal wires 22. Say the state.

In particular, in the metal fiber layer 20 according to the present embodiment, a plurality of (three sheets in FIG. 1B) metal fiber sheets 24 (first to third metal fiber sheets 24a to 24c) are laminated on the bag body 12. It has a structure, that is, a three-layer structure. Further, the metal fiber layer 20 is fixed to the inside of the bag body 12 and behind the chuck portion 30 (the gusset portion 16 side) over the entire surface of the pair of side surface portions 14 and the gusset portion 16. Therefore, the metal fiber layer 20 cannot be visually recognized from the outside of the bag body 12 with the chuck portion 30 closed. The first to third metal fiber sheets 24a to 24c may be laminated in a fixed state with each other, or may be non-fixed and separated from each other.

For example, as shown in FIG. 2A, the metal fiber sheets 24 (first to third metal fiber sheets 24a to 24c) are each formed into a mesh-like sheet by weaving a plurality of metal wires 22 by plain weave. That is, in the plurality of metal wires 22, the vertical metal wire 22a extending in the vertical direction and the horizontal metal wire 22b extending in the horizontal direction are alternately overlapped one by one (the upper and lower parts of the metal wire 22 are overlapped). By passing them alternately), it is configured to have a surface shape as a whole. The cross-sectional shape of each metal wire 22 may be, for example, a circular shape or a polygonal shape, and in the present embodiment, a wire body having a perfect circular cross section is adopted.

In particular, the wire diameters (maximum dimension of the line segment between the center point of the cross-sectional shape or the outer edge passing through the center of gravity) of the plurality of metal wires 22 (longitudinal metal wire 22a, horizontal metal wire 22b) are 0.1 mm to 0. It is preferably set to 2 mm, more preferably 0.1 mm to 0.17 mm. As a result, the metal fiber layer 20 has both rigidity that is not pierced by the puncture needle and flexibility that is plastically deformed by an external force.

If the wire diameter of the metal wire 22 is smaller (smaller) than 0.1 mm, there is a high possibility that the metal wire 22 will be broken when the puncture needle contacts and pushes the metal wire 22. That is, the puncture needle may break through the metal fiber layer 20. On the other hand, when the wire diameter of the metal wire 22 is thicker (larger) than 0.2 mm, the rigidity of the metal fiber layer 20 becomes too large, and it is difficult to obtain flexibility in which the container 10 is easily deformed. Become.

A mesh 23 (mesh: cavity) having an appropriate size is formed at a portion surrounded by the vertical metal wire 22a and the horizontal metal wire 22b. It is preferable that the metal fiber sheet 24 has an appropriately designed number of stitches 23 between the plurality of metal wires 22 in one inch. The number of the stitches 23 depends on the wire diameter of the metal wire 22, but is preferably set to, for example, 30 mesh to 100 mesh, and more preferably 50 mesh to 90 mesh.

If the number of eyes 23 is less than 30 mesh even though the metal wire 22 is thin, the opening ratio of the metal fiber sheet 24 becomes large and the puncture needle passes between the metal wires 22 (metal fiber layer 20). (Penetrate) is more likely. On the contrary, when the number of stitches 23 is larger than 100 meshes, the adjacent metal wires 22 come too close to each other and the rigidity of the sheet becomes high, which makes it difficult to obtain sufficient flexibility.

Further, in the metal fiber sheet 24, the opening ratio of the mesh-like sheet (the ratio of the opening area of the eyes 23 to the metal wire 22) is 20% to 50 in relation to the wire diameter of the metal wire 22 and the number of eyes 23. It is preferably set in the range of%. This is because if the opening ratio is smaller than 20%, the flexibility is lowered as described above, and if the opening ratio is larger than 50%, the penetration possibility of the puncture needle is increased as described above.

The metal wire 22 constituting the metal fiber layer 20 is not particularly limited, and for example, a metal material such as a stainless steel material, aluminum or an aluminum alloy, titanium or a titanium alloy can be applied. Examples of the stainless steel material include SUS301, SUS302, SUS303, SUS304, SUS305, SUS309, SUS310, SUS316, and SUS317. In particular, in the present embodiment, a stainless fiber made of SUS304 having good corrosion resistance, weldability, and mechanical properties is adopted.

The metal fiber sheets 24 (first to third metal fiber sheets 24a to 24c) constituting the metal fiber layer 20 are not limited to the plain weave mesh as shown in FIG. 2A, and may have various forms. Can be adopted.

For example, as shown in FIG. 2B, the metal fiber sheets 26 (first to third metal fiber sheets 26a to 26c) may be formed into a mesh-like sheet in which a plurality of metal wires 22 are woven by twill weave. That is, in the metal fiber sheet 26, a plurality of vertical metal wires 22a (two in FIG. 2B) are alternately superposed on each of the plurality of horizontal metal wires 22b, and similarly, a plurality of horizontal metal wires 22b are laminated. By alternately superimposing it on the vertical metal wire 22a, it has a planar shape as a whole.

The conditions of the metal fiber sheet 26 can be the same as those of the plain weave even in the twill weave. That is, the wire diameter of the metal wire 22 is 0.1 mm to 0.2 mm, the number of stitches 23 between the plurality of metal wires 22 in 1 inch is 30 mesh to 100 mesh, and the opening ratio is 20% to 50%. good. As described above, by providing the metal fiber layer 20 of the mesh-like sheet woven by plain weave or twill weave, the container 10 can be easily manufactured and the manufacturing cost can be reduced.

Further, as shown in FIG. 3, even if the metal fiber sheet 28 (first to third metal fiber sheets 28a to 28c) is composed of a non-woven sheet in which a plurality of metal wires 22 are randomly (irregularly) arranged. good. For example, the non-woven sheet is formed in a form like cotton wool by aggregating a plurality of curved, bent, meandering, etc. metal wires 22 at a high density, and has a planar shape as a whole.

Further, in the present embodiment, the metal fiber sheet 28 is point-fused at a part of a portion where the plurality of metal wires 22 intersect and overlap each other. In the metal fiber sheet 28 configured in this way, it is suppressed that the metal wires 22 individually move significantly when an external force is applied. That is, the metal fiber sheet 28 can suppress the separation of the metal wires 22 from each other to prevent the medical device from sticking out, and can obtain sufficient flexibility.

The plurality of metal wires 22 may not be point-fused together. Further, the conditions of the metal fiber sheet 28 are that the wire diameter of the metal wire 22 is 0.1 mm to 0.2 mm and the opening ratio is 20% to 50%, as in the case of plain weave.

As described above, the metal fiber layer 20 can obtain the physical properties of the entire layer even if the same material is used for the metal wire 22 by appropriately adopting the metal fiber sheets 24, 26, 28 of the plain weave, twill weave, and non-woven sheets. , Can be designed with a high degree of freedom.

Next, some methods for manufacturing the container 10 according to the present embodiment will be illustrated. The container 10 can be manufactured by carrying out a sheet molding step, a folding step, and a sealing step as shown in FIG. 4, for example.

Specifically, in the sheet forming step, the metal fiber layer 20 (three-layer metal fiber sheet 24) is fixed to the long film 40 constituting the bag body 12, and the laminated sheet 42 constituting the container 10 is first. To manufacture. The film 40 of the bag body 12 is provided as a series of rolls in which aluminum is vapor-deposited at a preliminary manufacturing stage. Further, the metal fiber sheet 24 is also provided in which the metal fiber sheet 24 is plain woven by a plurality of metal wires 22 at a preliminary manufacturing stage.

Therefore, in the sheet forming step, a series of metal fiber sheets 24 are cut into an appropriate size, and a predetermined layer is laminated and fixed to form the metal fiber layer 20. The metal fiber layer 20 may be formed by folding the metal fiber sheet 24 cut to a predetermined length.

Then, in the sheet forming step, the formed metal fiber layer 20 is attached to a predetermined position of the film 40 sent out from the roll. The film 40 and the metal fiber layer 20 may be fixed by welding, adhesion, or the like. The welding surface of the film 40 (the pair of side surface portions 14 of the bag body 12 and the inner surface of the gusset portion 16) may be coated with a welding layer that promotes welding with the metal fiber layer 20. Further, in addition to the metal fiber layer 20, the chuck portion 30 is sealed on the welded surface of the film 40 at an appropriate timing.

Then, in the folding step, in a bag-making and packaging machine (not shown), the laminated sheet 42 in which the film 40 and the metal fiber layer 20 are integrated is conveyed, and the laminated sheet 42 is folded so that the gusset portion 16 is formed at the bottom. As a result, the metal fiber layers 20 face each other inside the bag body 12. As a folding method using this bag making and packaging machine, a known method can be applied, and thus the description thereof will be omitted. In addition, a part of the above-mentioned processing of the sheet forming step (seal of the metal fiber layer 20 and the chuck portion 30 and the like) may be performed during transportation by the bag making and packaging machine.

Then, in the sealing step, the folded laminated sheet 42 is sealed by the bag making and packaging machine to form the side seal portion 18 and the bottom seal portion 19. In the formation of the side seal portion 18, by sealing so as to include a part of both sides of the opposing metal fiber layers 20, it is possible to prevent a gap from being generated at the boundary between the opposing metal fiber layers 20. As a result, the metal fiber layer 20 is satisfactorily fixed to the entire inner surface of the bag body 12 below the chuck portion 30.

Further, as shown in FIG. 5, the container 10 according to the present embodiment can be manufactured by inserting the metal fiber layer 20 into the bag body 12 that has been made into a bag. At this time, the metal fiber layer 20 may be folded up and down so as to have a gusset, and both sides in the folded state may be folded back. As a result, the container 10 can prevent the contained puncture needle from slipping through both side portions from the inside of the metal fiber layer 20 and penetrating the bag body 12. The metal fiber layer 20 may be configured to eliminate gaps between both side portions by sewing both sides after folding with a separately prepared metal wire 22.

Next, the operation and effect of the container 10 according to the present embodiment will be described.

As described above, the container 10 is carried by the user in a home-visit bag, and the medical equipment used for home-visit medical care and the like is discarded. Here, since the bag body 12 and the metal fiber layer 20 have flexibility, the container 10 is housed in the home-visit bag in a state of being plastically deformed into a shape that is easy to carry.

For example, when a medical device is not housed, the container 10 has a thin sheet shape in which the gusset portion 16 is crushed by bleeding air from the internal space 11 and sealing the container 10 with a chuck portion 30. On the other hand, when the medical device is housed, the container 10 exhibits a state of being inflated by the outer shape of the medical device. In either form, the container 10 can be made more compact than a hard box-shaped container, so that it can be easily carried.

Further, the puncture needle of a medical device has a sharp cutting edge at the tip, and if it is housed in a flexible bag body without the metal fiber layer 20, it easily protrudes when an external force is applied to the puncture needle. It ends up. On the other hand, the container 10 according to the present embodiment has the metal fiber layer 20 composed of the metal wire 22 of 0.1 mm to 0.2 mm, so that even if an external force is applied to the puncture needle, the cutting edge is subjected to an external force. Demonstrate sufficient resistance. That is, the metal wire 22 can be prevented from breaking, and the metal fiber layer 20 can satisfactorily prevent the puncture needle from sticking out (in other words, the sharp inclusion is exposed).

For example, in home visit medical care, a 21 gauge thick needle may be used as the largest puncture needle. The metal fiber layer 20 under the above-mentioned conditions (metal wire 22 wire diameter is 0.1 mm to 0.2 mm, number of eyes 23 is 30 mesh to 100 mesh, opening ratio is 20% to 50%) is applied to the piercing needle. However, the non-penetrating performance can be sufficiently exhibited.

As described above, the container 10 according to the present embodiment has the metal fiber layer 20 composed of the metal wire 22 having a wire diameter of 0.1 mm to 0.2 mm, so that the metal is made even if an external force is applied to the puncture needle. It is possible to prevent the wire 22 from breaking. Therefore, even if the medical device is discarded without recapping the puncture needle, the exposure of the puncture needle can be strongly prevented. Further, since the metal fiber layer 20 has flexibility, the container 10 can be freely deformed in shape according to the form of use, and can be easily carried, so that good usability can be obtained.

In this case, the container 10 is flexible by providing the metal fiber layer 20 in which the number of stitches 23 is set to 30 mesh to 100 mesh or the opening ratio is set to 20% to 50%. While doing so, the puncture needle can be satisfactorily non-penetrated. In particular, in the container 10, since the metal fiber layer 20 is made of a metal wire 22 made of stainless steel, it is possible to form a metal fiber layer 20 that is plastically deformable and has an appropriate hardness that is not broken by a medical device.

Further, since the container 10 is provided with a plurality of metal fiber layers 20, it is possible to more reliably prevent the exposure of the medical device. Moreover, the metal fiber layer 20 can be easily formed by folding or stacking a plurality of metal fiber sheets 24, and the manufacturing cost can be suppressed. Further, since the container 10 is provided with the metal fiber layer 20 on the entire inner surface of the bag body 12, the metal fiber layer 20 surrounds the internal space 11 without a gap and can prevent the medical device from breaking through.

The present invention is not limited to the above-described embodiment, and various modifications can be made according to the gist of the invention. For example, the container 10 can not only contain medical equipment but also various objects (particularly dangerous materials such as blades).

The container 10 is not limited to the bottom gusset type described above, and may have various shapes to which the metal fiber layer 20 can be provided. For example, as the container 10, a bag having no gusset portion 16, a gusset type bag having a gusset portion 16 on the side, or the like can be adopted. The container 10 may have a structure in which the metal fiber layer 20 is laminated on the outer peripheral surface (surface) side of the bag body 12. Even in this case, the exposure of the medical device can be prevented.

Further, the metal fiber layer 20 is composed of three layers (first to third metal fiber sheets 24a to 24c) in the present embodiment, but is not limited to this, and may be, for example, one layer or two layers, or It may be composed of four or more layers. Further, when the metal fiber layer 20 is composed of a plurality of layers, the physical properties (wire diameter, number of stitches, opening ratio, hardness, etc.) can be improved by adopting different types of metal wires 22 and woven states for each layer. Of course, it may be different for each.

A sample of the container 10 (two configuration examples and two comparative examples according to the present invention) was produced, and it was verified whether or not the medical device protrudes when the medical device is actually housed. The results will be described below with reference to FIG.

The container 10 according to the first configuration example was made of SUS304, and a metal fiber sheet 24 to which a metal wire 22 having a wire diameter of 0.12 mm was applied was formed. The metal fiber sheet 24 is a plain weave of 80 mesh and has an opening ratio of about 40%. Further, the metal fiber layer 20 is housed inside the bag body 12 as shown in FIG. 5 as a structure in which the above metal fiber sheets 24 are stacked in three layers.

The container 10 according to the second configuration example was made of SUS304, and a metal fiber sheet 24 to which a metal wire 22 having a wire diameter of 0.15 mm was applied was formed. The metal fiber sheet 24 is a plain weave of 60 mesh and has an opening ratio of about 27%. Further, the metal fiber layer 20 is housed inside the bag body 12 as a structure in which the above metal fiber sheets 24 are stacked in two layers.

The container 10 according to the first comparative example was made of SUS304, and a metal fiber sheet 24 to which a metal wire 22 having a wire diameter of 0.05 mm was applied was formed. The metal fiber sheet 24 is a plain weave of 80 mesh and has an opening ratio of about 70%. Further, the metal fiber layer 20 is housed inside the bag body 12 as a structure in which the above metal fiber sheets 24 are stacked in three layers.

The container 10 according to the second comparative example was made of SUS304, and a metal fiber sheet 24 to which a metal wire 22 having a wire diameter of 0.03 mm was applied was formed. The metal fiber sheet 24 is a plain weave of 300 mesh and has an opening ratio of about 40%. Further, the metal fiber layer 20 is housed inside the bag body 12 as a structure in which the above metal fiber sheets 24 are stacked in two layers.

That is, in the experiment, the container 10 of the first and second constituent examples has the metal fiber layer 20 under the above-mentioned conditions, while the wire diameter of the metal wire 22 of the metal fiber layer 20 is described above in the first and second comparative examples. It is configured to be thinner than the specified conditions. In the experiment, a puncture needle (a 23-gauge winged needle and a 21-gauge injection needle with a cap removed) and a glass ampoule were accommodated as medical devices, the chuck portion 30 was closed, and then the outside of the bag body 12 was used. An external force was applied to the puncture needle and glass ampoule.

As a result of the experiment, in the container 10 according to the first and second configuration examples, even if the puncture needle was pushed from the outside, the puncture needle protruded to the outside of the container 10, that is, the medical device was not exposed. Further, even if the glass amplifier was damaged by an external force, the fragments did not come out of the container 10. On the other hand, in the container 10 according to the first comparative example, when the puncture needle was pushed from the outside, the puncture needle pierced the metal fiber layer 20 and was exposed from the bag body 12. Further, in the container 10 according to the second comparative example, fragments of the glass ampoule pierced the container 10.

Therefore, the container 10 (container 10 according to the present invention) having the metal fiber layer 20 having a wire diameter of 0.1 mm or more of the metal wire 22 satisfactorily prevents medical equipment (puncture needle or fragment of glass ampoule) from sticking out. It can be said that it can be done. The container 10 according to the first and second configuration examples also had flexibility capable of being appropriately deformed.

As described above, by having the metal fiber layer 20 according to the present invention, the container 10 can be satisfactorily prevented from being exposed to a medical device such as a puncture needle, and can be freely deformed by appropriate flexibility. It can be said that.
