Description

  The present invention relates to a medical instrument package having a blister container body and a cover sheet for sealing the blister container body and enclosing the medical instrument.

  A medical device such as a syringe or an infusion bag used to administer a drug solution to a patient is sterilized, and is then transported or stored in a container or bag. As this container, a package called a blister package molded with a thermoplastic resin is used. This package body is made of a blister container body having a housing recess and an opening formed by molding, and joined at the periphery of the blister container body made of nonwoven fabric, resin film or aluminum foil while covering the opening of the blister container body. A cover sheet. In addition, a medical device is enclosed in the package. This prevents contamination of the medical device during transportation and storage.

  In particular, a prefilled syringe in which a syringe is pre-filled with a chemical solution or an autoinjector loaded with a cartridge filled with a chemical solution may be used for self-injection by a patient's own operation.

  Patent Document 1 discloses a package body having a blister container body having an opening on the top surface, and a cover sheet covering the opening and airtightly attached to the flange on the periphery of the opening by a roll seal. ing. A prefilled syringe is enclosed in this package. Medical workers and patients such as doctors and nurses open the package by peeling off the cover sheet from the flange immediately before injection. Thereafter, the prefilled syringe is taken out from the blister container body.

  To peel off the cover sheet from the flange, with your fingertips firmly grasping the non-joined part of the outer edge of the cover sheet and the knob slightly protruding from the outer edge, with a force that exceeds the adhesive force between the cover sheet and the flange The operation | movement of pulling and separating a cover sheet and a blister container main body is required.

  Since this operation requires a large force on the fingertip, it imposes a physical and mental burden on patients whose fingers are inconvenient due to diseases such as rheumatism, or who are old and cannot receive sufficient force. To prevent contamination of medical equipment during transportation and storage, in particular, the cover sheet and the flange are attached to the patient with a high adhesive force so that the cover sheet is not easily peeled off. It is difficult to peel off the sheet.

  Moreover, since a medical instrument is enclosed in the package, a blister is used to remove the cover sheet and open the package from the viewpoint of avoiding damage and contamination of the package by using a knife such as a scissors or a cutter. The container body and cover sheet cannot be cut.

  The medical device package can surely prevent contamination of the medical device, and at the same time, the finger is inconvenient and weak, but even in patients who need self-injection, It is desired that it can be easily opened by force.

JP 2007-302327 A

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a medical instrument package that can be easily opened with a slight force with a finger while preventing contamination and contamination of the medical instrument.

  The medical device package of the present invention made to achieve the above object includes a bottom portion, a peripheral wall portion extending continuously upward around the bottom portion, and an opening surrounded by an upper end of the peripheral wall portion. A blister container body that can accommodate a medical device, and a cover sheet that covers the opening and is joined to the periphery of the opening to seal the blister container main body. And an opening pull tab having an operation portion protruding from the cover sheet and a bonding surface bonded to the cover sheet, wherein the cover sheet and / or the opening pull tab is on the cover sheet. A guide part for guiding the tearing of the cover sheet from the opening pull tab according to the pulling and / or pulling of the operation part in the tearing direction from the opening pull tab; Than is. In addition, it is preferable that the said operation part is a finger hook part on which a finger is hung. Further, the peripheral edge of the opening may have a flange extending toward the outside of the blister container body.

  The medical instrument package is a guide notch that guides the tear by the guide portion being cut in the cover sheet along the tear direction at the joining surface, and is closed by the opening pull tab. It is preferable that it is removed.

  The medical device package has the two guide cuts, and the start cuts for starting the tearing on the operation unit side of the two guide cuts are provided on the cover sheet. It may be provided substantially perpendicular to the cut.

  It is preferable that the medical instrument package is an opening band in which the guide portion extends in the tearing direction while being connected to the operation portion of the opening pull tab.

  In the medical instrument package, it is preferable that the unsealing band has a wide part that gradually spreads in the direction opposite to the operation part and / or toward the operation part.

  In the medical device package, the opening pull tab may be formed of a material harder than the cover sheet.

  In the medical device package, the cover sheet is preferably formed of a stretched film having an orientation along the tear direction.

  The medical device package may be filled with the medical device which is any one of a syringe, a prefilled syringe, an injection needle, an infusion bag containing a chemical solution, or a cartridge containing a chemical solution.

  Since the medical device packaging body of the present invention includes an opening pull tab having a finger hook portion protruding at the outer edge of the cover sheet, it is easy to pull up and / or pull the finger after hooking the finger on the finger hook portion. It can be opened with simple operation. As a result, even if the patient has difficulty in finger movement or is difficult to apply force to the finger, the opening operation can be performed without requiring much force. Moreover, since the opening operation can be performed promptly, it contributes to the improvement of the work efficiency of the medical staff.

  Although the blister container body and the cover sheet are securely joined to each other, the medical instrument package can reliably prevent contamination and contamination of the encapsulated medical instrument. Since peeling of the joint portion with the cover sheet is not required, it is possible to achieve both the prevention of contamination and contamination of the medical instrument and the ease of opening.

  The medical device package has a simple structure consisting of only three members: the blister container body, the cover sheet, and the opening pull tab, so a large-scale manufacturing facility has been newly introduced to manufacture the medical device package. Therefore, existing manufacturing equipment can be used, and manufacturing can be performed simply, quickly, and at low cost.

  When the medical instrument package has a guide cut along the direction of tearing the cover sheet as the guide part, the guide cut is cut when the medical instrument package is opened. Therefore, the force required for the opening operation is further reduced.

  If the medical device package has a start cut cut into the cover sheet perpendicular to the guide cut, the force applied at the time of opening is concentrated on the guide cut. The force required at times can be further reduced, and medical staff and patients can quickly perform opening operations.

  If the medical device package has an opening band connected to the opening pull tab as a guide portion, the cover sheet can be torn along the opening band and opened, so the simplicity and certainty of the opening operation can be achieved. Can be improved.

  In the medical device package, when the cover sheet is formed of a stretched film having an orientation along the cutting direction of the cover sheet, the cover sheet is cut along the orientation, so that the tear resistance of the cover sheet is reduced. Therefore, the force required for opening can be further reduced.

It is a perspective view which shows the medical device packaging body to which this invention is applied immediately after the opening start, and the middle of the opening. It is a disassembled perspective view which shows the middle of manufacture of the medical device package which applies this invention. It is a perspective view which shows another medical device package body to which this invention is applied. FIG. 5 is a partially omitted perspective view showing a state immediately after the opening of the medical device package of FIG. 4 is completed. It is a perspective view of another medical device packaging body to which the present invention is applied. It is a perspective view of another medical device packaging body to which the present invention is applied.

  Hereinafter, although the form for implementing this invention is demonstrated in detail, the scope of the present invention is not limited to these forms.

  FIG. 1 shows a perspective view of an example of the medical device package 1 of the present invention. The medical device package 1 includes a blister container body 10 having an opening 13 opened at the top surface, and a cover sheet 20 that covers the opening 13 and seals the blister container body 10. An opening pull tab 30 is joined to the cover sheet 20. A sterilized prefilled syringe 40 is enclosed in the medical device package 1. The medical device package 1 is opened by pulling and / or pulling the opening pull tab 30.

  The blister container body 10 is formed of a transparent thermoplastic resin. The blister container body 10 includes a bottom part 11, a peripheral wall part 12 extending continuously upward around the bottom part 11, an opening part 13 surrounded by the upper end of the peripheral wall part 12, and a peripheral edge of the opening part 13. And a flange 14 protruding in the direction. The opening 13 has a substantially rectangular shape with arc-shaped corners, and two short sides of the substantially rectangular shape facing each other are a first short side 13a and a second short side 13b. A part of the peripheral wall portion 12 is along the outer shape of the prefilled syringe 40. Thereby, the movement of the prefilled syringe 40 in the medical instrument packaging body 1 is suppressed, and damage during transportation of the prefilled syringe 40 is prevented. In addition, an extraction groove 12 a into which a finger can be inserted is provided in a part of the peripheral wall portion 12 by forming a gap with the prefilled syringe 40.

  The cover sheet 20 has a substantially rectangular shape, and its outer edge 21 a overlaps the outer periphery of the flange 14. The cover sheet 20 is formed of a transparent thermoplastic resin film that is stretched so as to be oriented along the tearing direction S (see FIG. 2B). Since the blister container body 10 and the cover sheet 20 are formed of a transparent resin, the inside of the medical device package 1 can be visually recognized from the outside without opening. Thereby, the kind of the prefilled syringe 40 enclosed in the medical instrument package 1 and the presence or absence of breakage or contamination can be visually confirmed before opening.

  The outer edge portion 21 of the cover sheet 20 and the upper surface of the flange 14 are heat-sealed. Thereby, the cover sheet 20 is firmly joined to the blister container body 10 and is prevented from being unexpectedly peeled off from the flange 14. As described above, the blister container body 10 is hermetically sealed, so that the prefilled syringe 40 is reliably prevented from being contaminated / stained during transportation or storage.

  The opening pull tab 30 is harder and more colored than the thermoplastic resin film forming the cover sheet 20, or is formed of an opaque or translucent thermoplastic resin. The unsealed pull tab 30 has a flat outer shape in which a rectangle on the base end 31 side thereof and a semicircular shape on the tip end 32 side are combined. The opening pull tab 30 is joined to the cover sheet 20 by bonding the rectangle on the base end 31 side and the cover sheet 20 with an adhesive. The front end 32 side of the unsealed pull tab 30 is the first short side 13a side and protrudes outward from the outer edge 21a of the cover sheet 20 horizontally, and there is an annular finger hook hole 33 as a finger hook portion there. is open.

  At the joint surface between the cover sheet 20 and the opening pull tab 30, a guide cut 22 that is a guide portion and a start cut 23 are cut into the cover sheet 20. The guide cuts 22 form two parallel lines, and are along the longitudinal direction of the cover sheet 20, that is, the tearing direction S of the cover sheet 20. Thereby, the guide cut 22 guides the tearing of the cover sheet 20 when the medical instrument package 1 is opened.

  The start cut 23 forms a line perpendicular to the guide cut 22 and connects one ends of the guide cut 22 on the finger hooking hole 33 side. The start cut 23 prompts the start of the tearing of the cover sheet 20 so that the pulling force and the tensile force applied to the opening pull tab 30 are concentrated on the induction cut 22. Since both the cuts 22 and 23 are blocked by the opening pull tab 30, viruses and bacteria do not enter the blister container body 10 from the both cuts 22 and 23. Thereby, contamination of the prefilled syringe 40 is prevented. The width between the guide cuts 22 is preferably at least 1 mm, and more preferably 2 mm or more, although it depends on the size of the blister container body 10 and the cover sheet 20.

  FIG. 2A shows a state immediately after the opening of the medical device package 1 is started. A finger 51 of the hand 50 is caught on the tip 32 of the opening pull tab 30. The tip of the finger 51 is inserted into the finger hooking hole 33. The unsealed pull tab 30 is pulled up while drawing a locus indicated by a two-dot chain line arrow in the drawing with the base end 31 as a fulcrum by the finger 51 and stands on the cover sheet 20. The cover sheet 20 is cut into a rectangle along both cuts 22 and 23, and the outlet 24 is slightly opened. The opening pull tab 30 is peeled off from the cover sheet 20 together with the cutout portion 20a corresponding to the takeout opening 24 from which the coversheet 20 has been cut off.

  Since the medical instrument package 1 has the finger hooking hole 33 protruding at the outer edge 21 a of the cover sheet 20, the finger 51 can be easily hooked into the finger hooking hole 33. Moreover, since the opening pull tab 30 is conspicuous by being joined on the cover sheet 20, even a patient who is unfamiliar with the handling of a medical instrument can recognize and understand the opening method at a glance. In addition, both the cuts 22 and 23 cut in advance in the cover sheet 20 serve as an opportunity for tearing the cover sheet 20. Therefore, it is sufficient to raise the finger hook hole 33 with the base end 31 as a fulcrum, erect the opening pull tab 30 on the cover sheet 20, and peel off a part of the joint surface between the cover sheet 20 and the opening pull tab 30. A large force is not required at the start of opening the medical device package 1.

  FIG. 2B shows the middle of opening the medical device package 1. The opening pull tab 30 is pulled toward the second short side 13 b above the cover sheet 20 by the force of the hand 50. Thus, the cover sheet 20 is cut from the first short side 13a side to the second short side 13b along the cutting direction S, which is a direction straddling the straight line. As a result, the medical device package 1 is opened, and a rectangular outlet 24 is opened in the cover sheet 20. A part of the prefilled syringe 40 is exposed at the outlet 24.

  The cutout portion 20a follows the unsealed pull tab 30 and is pulled in the same manner. The cover sheet 20 and the cutout portion 20a are connected by a folded portion 20b that is folded back in the pulling direction by pulling the opening pull tab 30. The folded portion 20b approaches the second short side 13b according to the tension of the opening pull tab 30. Thereby, the outlet 24 becomes wider gradually.

  According to this medical instrument package 1, a medical worker or a patient simply hooks the finger 51 into the finger hook hole 33 and pulls up or pulls the opening pull tab 30, and does not apply much force to the finger 51. The opening operation of the medical instrument package 1 can be performed. Accordingly, there is no need to pick the cover sheet 20 or peel off the joint between the cover sheet 20 and the flange 14, so that it is difficult to move the hand or fingertip due to a disease such as rheumatism, or a sufficient force to reduce muscle strength. Even a patient who does not have an opening can be easily opened.

  Since the cover sheet 20 is formed of a stretched film parallel to the guide cuts 22, that is, oriented along the cutting direction S, it is easy to tear along the cutting direction S of the opening pull tab 30. As a result, the cover sheet 20 can be torn simply by pulling up or pulling the opening pull tab 30 with a force lower than that without maintaining the force at the start of opening.

  In addition, since the opening pull tab 30 is formed of a relatively hard resin, the opening pull tab 30 is not deformed or broken by pulling by the finger 51 placed on the finger hooking hole 33 during the opening operation. Thereby, the opening pull tab 30 can transmit the response by the tearing of the cover sheet 20 to the hand 50 through the finger 51. As a result, the patient or the like who performs the opening operation can recognize that the opening operation has progressed reliably.

  Moreover, since a tool such as a blade is not required for the opening operation, the medical device package 1 can be quickly opened and the prefilled syringe 40 can be taken out even when the user is away from home.

  The medical instrument package 1 can be opened by a simple operation as described above. Thereby, since the preparation work for injection is promptly performed, not only the work burden of the patient as described above, but also the work burden of a medical worker or the family of a patient receiving home medical care is reduced.

  When the folded portion 20b reaches the second short side 13b, the opening operation of the medical instrument package 1 is completed, and the prefilled syringe 40 is exposed at the outlet 24 so as to be removable.

  As described above, the medical device packaging body 1 can join the blister container body 10 and the cover sheet 20 with a high joining force to reliably prevent the prefilled syringe 40 from being contaminated or soiled, and at the time of opening the blister container body Since it is not necessary to peel off the joint portion between the ten flanges 14 and the outer edge portion 21 of the cover sheet 20, it can be easily opened with a small force.

  A method for manufacturing the medical device package 1 will be described with reference to FIG. First, the blister container body 10 and the opening pull tab 30 are molded.

  Next, a uniaxially stretched film to be the cover sheet 20 is prepared, both cuts 22 and 23 are cut at predetermined positions, and cut into an outer shape slightly larger than the outer shape of the flange 14 of the blister container body 10.

  The prefilled syringe 40 is accommodated in the blister container body 10, and both incisions 22 and 23 are positioned closer to the first short side 13 a of the opening 13 of the blister container body 10, while the long side direction of the flange 14 and the orientation of the extension are The openings 13 and the flanges 14 are covered with a uniaxially stretched film so that they are parallel to each other. The outer edge portion 21 of the cover sheet 20 and the flange 14 are joined by heat fusion or adhesion.

  An adhesive is applied to one surface of the opening pull tab 30 on the base end 31 side. The opening pull tab 30 is thermally fused to the cover sheet 20 so that the finger hooking hole 33 protrudes horizontally from the outer edge 21a on the first short side 13a side while closing both the notches 22 and 23 on the surface where the adhesive is applied. Join by adhesion or adhesion. In this way, the medical device package 1 is completed. The medical instrument package 1 is packed and transported to the home of a patient who is receiving medical care or home medical care.

  Since the medical device package 1 has a simple configuration and only requires three members, the blister container body 10, the cover sheet 20, and the opening pull tab 30 to enclose the prefilled syringe 40, and quickly Can be manufactured in large quantities. Moreover, since the medical device packaging body 1 has the blister container body 10 and the cover sheet 20 that are also used in conventional packaging bodies, existing manufacturing equipment can be used as it is. Thereby, since it is not necessary to introduce a large-scale manufacturing facility newly in order to manufacture the medical instrument packaging body 1, it can manufacture simply and at low cost.

  The medical instrument package 1 is used as follows. First, after unpacking, the medical device package 1 is placed on a horizontal table (not shown). Next, the flange 14 is pressed toward the base with the other hand of the hand 50 to fix the medical device package 1. The tip of the finger 51 is inserted into the finger hook 33 so as to cover the tip 32 from the lower surface to the upper surface of the finger hook 33. Further, the joint on the tip side of the finger 51 comes into contact with the edge of the finger hooking hole 33.

  By pulling up the finger hooking hole 33 with the finger 51 (see FIG. 2A), the opening pull tab 30 stands on the cover sheet 20 so that the tip 32 draws an arc centered on the base end 31. The cover sheet 20 and the opening pull tab 30 are peeled in a region sandwiched between the start cut 23 and the outer edge 21a opposite to the start cut 23. The opening pull tab 30 is inverted by the subsequent operation of the finger 51 so that the start cut 23 opens widely, and the cover sheet 20 follows the open pull tab 30 so that the area cut along both the cuts 22 and 23 is rolled. The outlet 24 opens.

  The cover sheet 20 is cut off by pulling the pull pull tab 30 with the hand 50 while pulling the pull pull tab 30 upside down. When the folded portion 20b reaches the second short side 13b, the medical worker or patient recognizes that the opening operation has been completed by the response generated at this time.

  The prefilled syringe 40 is taken out from the medical device package 1 by being picked up by a fingertip inserted into the takeout groove 12a, and the injection needle is removed after the cap that forms a substantially hexagonal column screwed to the tip is removed. Is attached for injection. The medical device package 1 is inverted so that the opening 13 is positioned downward and the bottom 11 is positioned upward, so that the prefilled syringe 40 can be removed from the low position by, for example, gently dropping it onto a tray. Good. According to this, the prefilled syringe 40 can be easily taken out even if the patient is unable to move the fingertip, such as a rheumatic patient.

  When the blister container body 10 is formed of a hard resin that is not deformed by the force of fingers, when the medical instrument package 1 is opened, it can be pressed against the table and firmly fixed to perform the opening operation. According to this, the medical device packaging body 1 can be fixed by an arm without using a hand. On the other hand, if the blister container body 10 is formed of a soft resin that can be deformed by the force of fingers, when the medical instrument package 1 is opened, the blister container body 10 is firmly grasped with one finger, The other finger can be inserted into the finger hooking hole 33 to perform the opening operation.

  The outer surface of the cover sheet 20 may be provided with medical device information such as manufacturer name, trade name, product number, volume, dose, ingredient, and / or precautions for use. Such information may be a barcode or a QR code (registered trademark). The information may be attached by printing, or may be attached by attaching a label on which the information is described.

  Examples of the material of the cover sheet 20 include paper and nonwoven fabric in addition to the thermoplastic resin as described above. Note that the cover sheet 20 may be opaque.

  Examples of the adhesive that bonds the cover sheet 20 and the opened pull tab 30 include an acrylic pressure-sensitive adhesive mainly composed of poly (meth) acrylate. Examples of poly (meth) acrylates include methyl acrylate, ethyl acrylate, propyl acrylate, butyl acrylate, 2-ethylhexyl acrylate, methyl methacrylate, ethyl methacrylate, propyl methacrylate, and butyl methacrylate. Examples thereof include a homopolymer obtained by polymerizing a monomer selected from (meth) acrylic acid alkyl esters, and a copolymer obtained by copolymerizing any of them. In addition, at least one of these monomers and 2-hydroxyethyl acrylate, 2-hydroxypropyl acrylate, 3-hydroxypropyl acrylate, 3-hydroxybutyl acrylate, and 4-hydroxy acrylate Hydroxyl-containing (meth) acrylic such as butyl, 2-hydroxyethyl methacrylate, 2-hydroxypropyl methacrylate, 3-hydroxypropyl methacrylate, 3-hydroxybutyl methacrylate, 4-hydroxybutyl methacrylate Acid alkyl esters; (meth) acrylic acids such as acrylic acid and methacrylic acid; vinyl esters such as vinyl acetate and vinyl propionate; cyano group-containing compounds such as acrylonitrile and methacrylonitrile; amide groups such as acrylamide Compound; Styrene, can be mentioned at least one copolymer of monomers selected from aromatic compounds such as vinyl pyridine.

  As a method for joining the outer edge portion 21 and the upper surface of the flange 14, these adhesives may be used instead of heat fusion.

  Moreover, as a sterilization processing method of the blister container main body 10, the cover sheet 20, and the opening pull tab 30, an ethylene oxide gas sterilization process, a gamma ray sterilization process, and an electron beam sterilization process other than a high temperature steam sterilization process are mentioned.

  In addition to the prefilled syringe 40, the medical instrument package 1 may be filled with an autoinjector, a syringe, an injection needle, an infusion bag containing a chemical solution, or a cartridge containing a chemical solution. Among these, prefilled syringes and autoinjectors that are used in home medical care and are often handled by patients themselves and have an elongated outer shape are preferable.

  FIG. 4 shows another embodiment of the medical device package 1. FIG. 1 is a perspective view showing another embodiment of the medical device packaging body 1 before opening.

  The opening pull tab 30 of the medical device package 1 includes a finger hook ring 34 that is a finger hook portion that protrudes horizontally toward the outside of the cover sheet 20 at the outer edge 21a on the first short side 13a side, and this finger hook. It is connected to the ring 34, and has an unsealing band 35 that is a band-shaped guiding portion that extends along the cutting direction S and extends straight toward the second short side 13 b. The opening pull tab 30 is bonded to the inner surface of the cover sheet 20, that is, the surface facing the bottom portion 11 of the blister container body 10. The opening pull tab 30 including the finger ring 34 and the opening band 35 is integrally formed of a resin harder than the cover sheet 20.

  The unsealing band 35 has a wide portion 36 whose width gradually increases from the second short side 13b to the end rather than the middle. The end of the wide portion 36 overlaps the second short side 13b.

  A guide cut 22 is cut into the cover sheet 20 between the first short side 13a and the outer edge 21a. The guide cut 22 is cut along the edge of the opening band 35 so as to reach the outer edge 21a. The guide cut 22 does not reach the first short side 13a. Thereby, sealing of the medical instrument package 1 is ensured.

  FIG. 5 shows a partially omitted perspective view immediately after opening the medical device package 1 of FIG. After the finger 51 is hung on the finger ring 34, the finger ring 34 is pulled up, whereby the unsealing band 35 joined to the inner surface of the cover sheet 20 is pulled up. At this time, the guide sheet 22 is triggered, and the cover sheet 20 is torn along the edge of the opening band 35. As a result, the elongated strip-shaped outlet 25a is opened from the opening stage to the middle stage, and the medical instrument package 1 is opened. Since the unsealing band 35 has the wide portion 36, the wide wide outlet 25b connected to the strip-shaped outlet 25a is opened at the end of the opening. At this time, since the wide portion 36 has a gradually wider shape toward the second short side 13b, a sharp increase in the tear resistance of the cover sheet 20 is prevented. Thereby, the force required to pull the opening pull tab 30 is reduced.

  As described above, since the opening pull tab 30 has the opening band 35, even if the medical instrument packaging body 1 is inclined unexpectedly after opening, the cover sheet 20 becomes a resistance and the prefilled syringe in the blister container main body 10 is provided. 40 does not fall unexpectedly. As a result, the prefilled syringe 40 is prevented from being damaged or soiled due to an unexpected drop.

  A medical worker or patient can take out the prefilled syringe 40 by inserting a fingertip into the wide outlet 25b and picking up the prefilled syringe 40. At this time, the prefilled syringe 40 is taken out so as to push and widen the strip-shaped outlet 25a. Further, by fixing the prefilled syringe 40 and moving the second short side 13b in the direction of the bottom portion 11, the prefilled syringe 40 can be removed so as to be exposed.

  FIG. 6 shows another embodiment of the medical device package 1. As shown to the figure (a), the medical device package 1 may have the opening pull tab 30 to which the opening belt | band | zone 35 is connected to the lower surface by the side of the base end 31 side. The unsealing band 35 penetrates the cover sheet 20 via the through hole 26 opened in the cover sheet 20, and is bonded and joined to the inner surface thereof. The guide cut 22 is cut into the cover sheet 20 so as to extend two sides of the through hole 26 along the cutting direction S (see FIG. 4). The through hole 26 and the guide cut 22 are closed by the opening pull tab 30. According to this medical instrument package 1, since the finger hook hole 33 can be caused by using the base end 31 as a fulcrum, and the cover sheet 20 can be torn by the opening band 35, the medical instrument packaging can be performed with much less force. The body 1 can be opened.

  As shown in FIG. 6B, the wide portion 36 may be provided at both ends of the opening band 35. The wide portion 36 on the finger hooking hole 33 side gradually widens toward the finger hooking hole 33. According to this medical instrument package 1, the simplicity of extraction can be improved.

  FIG. 7 shows another embodiment of the medical device package 1. This medical device package 1 encloses an infusion bag 41 containing peritoneal dialysis fluid and the like. The dose of the peritoneal dialysis solution varies depending on the morphological variety, composition, and concentration according to the pathology and dialysis method of the peritoneal dialysis patient, but is approximately 1 to 2 L. Therefore, the infusion bag 41 is compared with a prefilled syringe or cartridge. And large. Therefore, the medical instrument packaging body 1 enclosing the infusion bag 41 is also large.

  The tip 32 of the opening pull tab 30 has a plurality of concave and convex shapes. The concave portion is formed with a gentle curve so that the four fingers of the index finger, the middle finger, the ring finger, and the little finger can be hung.

  As indicated by a two-dot chain line in FIG. 7, the medical staff or patient brings the four fingers 51 into contact with the concave portion of the tip 32 of the opening pull tab 30 and grips the tip 32 with the hand 50. Furthermore, the medical instrument package 1 can be opened by pulling up and pulling the opening pull tab 30. As described above, since the four fingers 51 are hung on the finger hook hole 33, the medical device package 1 can reduce the force applied to one finger and can be opened using the muscles of the entire arm or the back muscles. It is something that can be done. Thereby, since the encapsulated medical instrument is large, even if a wide outlet 24 is required, it can be easily opened with a weak force.

  The medical device package of the present invention is used to keep a sterilized medical device clean and prevent breakage and fouling while transporting and storing it and opening it under a patient.
