  In particular, as a package used in the medical field, for example, a package housing a medical device can be cited. In this case, the medical device is sterilized and then stored in a clean space formed inside the package, so that the sterile state of the medical device is maintained until use.

  By the way, in diagnosis and treatment using a medical device, an operator who is in direct contact with a patient touches only a sterilized medical device on the basis of preventing hospital infection. Therefore, when using a medical device, a nurse or the like who does not directly contact the patient provides the surgeon with a medical device that is stored, for example, by being lifted hollow and opened without placing the package on the desk. The surgeon himself takes out the medical device from the opened package. At this time, if the medical device is stuck to the storage surface of the film constituting the package or is located at the back of the storage space, the surgeon takes time to remove the medical device. During surgery, it puts a great burden on the patient.

  Moreover, in such a case, there is a risk that the operator may accidentally contact the non-sterile part of the package because of the time required for the work.

  An object of the present invention is to solve this kind of problem, and to provide a package capable of facilitating the removal of the medical device from the package and smoothly performing the delivery operation of the medical device during the operation. And

In the present invention, a packaging material in which a first and a second film are joined via a seal portion provided at a peripheral portion thereof, and an accommodation space is provided between the first and second films, and the accommodation space A holder that holds the items to be stored in the package,
The first film is provided with a guide piece having one end fixed to the accommodation surface and the other end as a free end and directed to the opening start portion of the packaging material,
The other end of the guide piece is inserted into a through hole formed in the holder,
The guide piece has an inclination angle of the other end of the guide piece toward the second film as the packaging material is opened and the first film and the second film are separated from each other. It is characterized by tilting to become large.

  And in this invention, while the said holder has a handle part, it is preferable that the said handle part is arrange | positioned so that it may point to the said opening start part of a said 1st film.

  In the present invention, a handle hole may be provided in the handle portion.

  Furthermore, it is preferable that the holder moves toward the other end of the holder as the guide piece tilts.

  Still further, the package may be configured such that a stored item as a medical device is stored, and the holder is provided with a holding unit that holds another medical device related to the stored item.

  In the present invention, one end of the guide piece is fixed to the accommodation surface of the first film constituting the packaging material, and the other end of the guide piece is inserted into the through hole formed in the holder for holding the contents, When the material is opened, as the first film and the second film are separated from each other, the other end of the guide piece tilts toward the second film, whereby the holder is supported by the guide piece. Therefore, it becomes easy to take out the holder holding the medical device from the opening formed by separating the first film and the second film, and the delivery can be performed smoothly.

  In addition, since the holder handle portion is arranged to face the opening start portion, the operator holds the holder handle portion from the opening or inserts a finger into the handle hole provided in the handle portion. And can be easily taken out.

  At this time, the holder can be further easily removed by moving the holder toward the other end of the guide piece along with the tilting of the guide piece.

  In this case, if the holder holds other medical devices related to the stored items, other related medical devices that are sterilized together with the stored items can be taken out at the same time.

It is a schematic plan view of the package which concerns on 1st Embodiment of this invention. It is a schematic exploded perspective view of the package shown in FIG. FIG. 3 is a schematic perspective view seen from the side when the package shown in FIG. 1 is opened. 4A is a schematic vertical cross-sectional view taken along line IV-IV showing a state before the package shown in FIG. 1 is opened, and FIG. 4B is a schematic vertical cross-sectional view showing a state after the package is opened. It is a schematic plan view of the package which concerns on 2nd Embodiment of this invention.

  FIG. 1 is a schematic plan view of a package 10 according to the first embodiment of the present invention, and FIG. 2 is a schematic exploded perspective view of the package 10. The package 10 is formed by laminating a first film 12 and a second film 14 through a seal portion 16 provided at a peripheral portion thereof, and the first film 12 and the second film 14 are laminated. It consists of a packaging material 20 in which a storage space 18 is formed, and a holder 24 for holding the storage object 22 stored in the storage space 18.

  In the accommodation space 18 in the package 10, a medical device is accommodated as the accommodation 22. Examples of the medical device include a catheter treatment medical device inserted into a puncture hole connected to an artery such as a patient's arm or leg. Specifically, for example, an angiographic catheter, an angiographic catheter guide wire, a microcatheter, a PTCA (percutaneous vasodilatation) guiding catheter (right heart shape, left shape, etc.), PTCA guide wire In addition, instruments used for diagnosis and treatment, such as PTCA balloon catheters and stent delivery catheters, and drugs such as angiographic contrast agents are suitable. In this case, the catheter or guide wire may be stored in a state of being packaged by a packaging member such as a holder tube.

  The wrapping material 20 includes a first film 12 and a second film 14 which are provided at the peripheral edge thereof and joined together via a seal portion 16, and are integrated between the first and second films 12 and 14. A storage space 18 is formed. The interior of the accommodation space 18 is a sterilized space.

  Although FIG. 1 shows an example in which both the first film 12 and the second film 14 have a rectangular shape, the shape is not limited to such a shape. For example, a triangular shape, a polygonal shape, Various shapes can be employed in addition to the circular shape. Moreover, since the sterilized accommodation space 18 should just be formed between the 1st film 12 and the 2nd film 14, the 1st film 12 and the 2nd film 14 do not necessarily need to be the same shape.

  Instead of the seal portion 16 made of an adhesive, the first film 12 or the second film 14 may be made of, for example, a material having heat sealability (heat fusion property) in any one of the films. As such a material, for example, a resin material such as a polyolefin resin such as polyethylene or polypropylene, a blend resin of these polyolefin resins, or a polyester resin such as polyethylene terephthalate can be suitably used.

  In this case, the other film may be a material having heat sealability or a material not having it. For example, in addition to polyethylene as described above, single-layer films such as polyvinylidene chloride, vinyl chloride-vinylidene chloride copolymer, metal foils such as aluminum, silica, etc. deposited on these films, aluminum films, aluminum laminate films, etc. Alternatively, a film containing a metal foil can be used. Furthermore, it is also possible to use a laminate in which two or more of these films are laminated. Moreover, you may use a plastic nonwoven fabric and paper.

  Since the packaging material 20 is sterilized, it is desirable to be able to withstand various sterilization processes such as high-pressure steam sterilization, EOG sterilization, and gamma ray sterilization. It should be possible. Furthermore, it is preferable that one of the first and second films 12 and 14 uses a transparent material in order to confirm the contents 22. In the first embodiment of the present invention, a transparent material is used for the first film 12.

  At one corner portion 40 of the first and second films 12 and 14 constituting the packaging material 20, the first and second opening start portions 38a and 38b are provided in a stacked state. The first and second opening start portions 38a and 38b may be provided in one place on the square-shaped first and second films 12 and 14, but may be provided at four corner portions of the square shape as necessary. May be. Further, for example, when the first and second films 12 and 14 are square, the center of one edge of the packaging material 20 obtained by joining the peripheral portions of the first and second films 12 and 14 is used. You may provide the 1st and 2nd opening start part 38a, 38b in a part. In addition, the first and second opening start portions 38a and 38b may be provided at appropriate positions according to the shape of the film, such as a circular shape, an elliptical shape, or a triangular shape, without being limited to a square shape. However, as shown in FIGS. 1 and 2, when the first and second opening start portions 38a and 38b are provided at the corner portions 40 of the first and second films 12 and 14 constituting the packaging material 20, It is preferable in terms of easy opening of the opening and easy removal of the contents 22.

  The seal portion 16 can be peeled, and the first seal portion 42 that is once bent at one corner portion 40, and the second seal portion 44 that is bent at the other corner portion 50 that does not need to be peeled off at the time of opening. And have. The seal portion 16 is formed so as to surround the accommodation space 18 by connecting the first seal portion 42 and the second seal portion 44 at their end portions. Thereby, isolation | separation with the accommodation space 18 sterilized and the exterior which is not sterilized is achieved. In FIG. 1, the seal portion 16 has a substantially similar shape of these films along the peripheral edge portions of the first and second films 12 and 14, but is not limited thereto. For example, the shape of the seal portion 16 may be changed according to the shape of the accommodation 22.

  As described above, the seal portion 16 can be formed by using an adhesive or by heat sealing (thermal fusion) of a film material. Alternatively, the seal portion 16 may be formed by adhesion with a solvent, for example. Since the first seal portion 42 is on the peeling side and the second seal portion 44 is on the non-peeling side, the peeling strength, that is, the bonding strength of the second seal portion 44 can be made larger than that of the first seal portion 42. preferable. For example, changing the temperature and pressure of thermocompression bonding at the time of heat sealing between the first seal part 42 and the second seal part 44, using different adhesives for the first seal part 42 and the second seal part 44, It is possible to adjust the peel strength of each of the first and second seal portions 42 and 44 by changing the width of the first seal portion 42 and the second seal portion 44.

  And the guide piece 28 which consists of a rectangular-shaped board is provided in the inner side of the 1st film 12, ie, the accommodating surface 26a. One end 29 of the guide piece 28 is fixed to the first film 12, and the other end 31 is formed as a free end. The other end 31 of the guide piece 28 is accommodated in the packaging material 20 in a state of being inserted into a through hole 30 provided in the holder 24. The fixing position of the one end portion 29 of the guide piece 28 is preferably on the diagonal line including the corner portion 40 where the first opening start portion 38a is provided, and is approximately the center portion on the diagonal line, or more substantially than the center portion. More preferably, it is provided on the other corner portion 50 side on the diagonal line of one corner portion 40 provided with one opening start portion 38a. If the fixing position of the guide piece 28 is too close to the first opening start portion 38a, the guide piece 28 itself is shortened and the guide piece 28 is detached from the through hole 30 of the holder 24 when the packaging material 20 is opened. Or the holder 24 cannot be moved to a position where it can be easily taken out.

  Therefore, the length of the guide piece 28 can be adjusted in the range from the approximate center to the one corner portion 40, for example, when the one end portion 29 of the guide piece 28 is fixed to the approximate center. When fixed to the other corner portion 50 facing the one corner portion 40, the length can be adjusted within a range from the other corner portion 50 to the one corner portion 40. In this case, the shape of the guide piece 28 is not particularly limited, such as a rectangular shape as shown in FIG. 1 or a rod shape, but is preferably a long shape having a predetermined length as described above.

  The guide piece 28 and the holder 24 can employ the same material as the first or second film 12, 14 described above, and the fixing of the one end portion 29 of the guide piece 28 to the first film 12 is similarly performed by heat sealing. A fixing form using other adhesive or the like can be adopted. Since the guide piece 28 is sterilized together with the packaging material 20, it is desirable that the guide piece 28 can withstand the various sterilization processes described above.

  Since the holder 24 is for holding a medical device that is the container 22, it is preferable to use a material having a predetermined strength. For example, when the same material as the first or second film 12 or 14 is used, it is preferable to make the thickness (plate thickness) of the material larger than these. Further, since the holder 24 is housed in the housing space and is sterilized, it is desirable that the holder 24 can withstand the above-described various sterilization processes in the same manner as the packaging material 20 and the guide piece 28.

  As shown in FIG. 1, the holder 24 has a three-pronged shape, and has three leg portions 24a, 24b, and 24c, and the leg portions 24a, 24b, and 24c are respectively latched for holding the contents 22 therein. Pieces 25a, 25b, and 25c are provided. The shape of the holder 24 is not limited to the three-pronged shape in FIG. 1, and various shapes such as a square shape, a triangular shape, a polygonal shape, and a circular shape can be employed. The size of the holder 24 only needs to be able to hold the accommodation 22 in the accommodation space 18, and therefore can be appropriately selected depending on the size of the accommodation 22. In this case, the locking pieces 25a, 25b, and 25c have a U-shaped cutout of the same member as the holder 24, with one end serving as a fixed end and the other end serving as a free end. The leg portion 24 c of the holder 24 is used as a handle portion 32, and a handle hole 34 is provided in the handle portion 32.

  As shown in FIG. 1, the handle portion 32 of the holder 24 is arranged so as to be directed to the first opening start portion 38a.

  The packaging body 10 according to the first embodiment of the present invention is basically configured as described above. Next, the operation for taking out the contents 22 such as a guide wire from the packaging body 10 will be described. This will be described with reference to FIGS. 3, 4A, and 4B. 4A and 4B each represent a cross section along a substantially diagonal line from one corner portion 40 provided with the opening start portion 38 of the package 10 to the other corner portion 50.

  First, the object 22 to be wound in a linear shape, for example, a guide wire is positioned in the accommodation space 18 and sandwiched between the locking pieces 25a, 25b, and 25c of the holder 24 (see FIG. 4A). . In this case, the guide piece 28 is in a state where the other end 31 side is inserted into the through hole 30.

  FIG. 3 shows a state where the first and second opening start portions 38a and 38b provided on the first and second films 12 and 14 are gripped with both hands in order to open the packaging material 20. FIG. Therefore, for example, the nurse opens the first opening start portion 38a and the second opening start in a state where the nurse holds the first opening start portion 38a with the right hand and holds the second opening start portion 38b with the left hand and lifts it hollow. The part 38b is separated and opened. Preferably, if the force applied to the first opening start portion 38a is greater than the force applied to the second opening start portion 38b, the guide piece 28 having the one end 29 fixed to the accommodation surface 26a of the first film 12 in advance is secured. It is easy to incline the other end 31 that is a free end toward the second film 14.

  As shown in FIG. 4B, when the first film 12 is peeled from the second film 14, the other end portion 31 of the guide piece 28 having one end portion 29 fixed to the first film 12 is attached to the second film 14. As a result, the first film 12 is relatively separated so as to push up. That is, the first film 12 is separated from the second film 14, and the package 10 is opened.

  As described above, when the package 10, that is, the packaging material 20 is opened, the operator holds the handle portion 32 of the holder 24 instead of the nurse, or inserts the finger into the handle hole 34 and inserts the finger. 24 is pulled out of the packaging material 20. Thus, the contents 22 held by the locking pieces 25a, 25b, and 25c of the holder 24 are taken out together with the holder 24 that moves along the guide piece 28.

  In this case, as indicated by phantom lines in FIG. 4B, when the angle formed by the guide piece 28 and the first film 12, that is, when the inclination angle of the guide piece 28 is small, the holder 24 is positioned in the vicinity of the first film 12. However, as the inclination angle increases, the holder 24 moves to the other end 31 side of the guide piece 28. As a result, for example, the handle portion 32 of the holder 24 can be positioned in the middle of the opening 36, and the handle 32 can be projected outside the opening 36. By setting the handle portion 32 to such a position, the handle portion 32 is separated from the opening start portion 38 which is a non-sterile portion and the outer surface of the packaging material 20, so that the operator mistakenly places the non-sterile portion of the package 10. It becomes easy to pull out the holder 24 from the packaging material 20 without contacting.

  In order to position the handle portion 32 of the holder 24 at an intermediate position of the opening 36 or to protrude outside, for example, the first opening start portion 38a is slightly upwardly directed from the second opening start portion 38b. Open it. In this case, as shown in FIG. 4B, the holder 24 is supported by the guide piece 28 in the accommodation space 18. At this time, due to the balance between the weight of the holder 24 and the contents 22 held by the holder 24 and the friction between the holder 24 and the guide piece 28, the other end 31, which is the free end of the guide piece 28, Inclined toward the two-film 14. As a result, the holder 24 moves toward the other end 31 as the guide piece 28 tilts, and the handle 32 reaches a position where it can be easily pulled out by the operator.

  FIG. 5 is a schematic plan view of the package 52 according to the second embodiment. Here, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the present embodiment, the holder 54 has a substantially rectangular shape, and other medical devices (container 22a, container 22b) such as a connector, for example, related to the container 22 which is a medical device are attached to the holder 54. A holding portion 56 for holding is provided. The holding portion 56 has two strips formed by cutting the holder 54 along four parallel line segments, and a holding piece 58 for holding the contents 22a between the holder 54, The holding hole 60 which fits and holds the accommodation 22b can be illustrated. The effect that one holder 54 is useful for holding and taking out the medical device related to taking out the contents 22 can be obtained. The holding part 56 may be provided in the holder 54 of the first embodiment.

  The present invention is not limited to the above-described embodiment, and various configurations can be adopted without departing from the gist of the present invention.
