[0004] JP 2000-25892 A Japanese Patent No. 6715384 A

[0005] When removing a protective cap using the medical tool of JP 2000-25892 A and then disinfecting the end of a medical container using another tool such as that disclosed in Japanese Patent No. 6715384 A, it is necessary to use two different tools, which is cumbersome.

[0006] The present disclosure aims to solve the above-mentioned problems.

[0007] (1) An aspect of the present disclosure is a medical tool for removing a protective cap from a container body of a medical container and disinfecting a sealing portion provided at the mouth of the container body, the medical tool comprising: a holder having an internal space capable of accommodating at least a portion of the container body and the protective cap; an operating member having a cap removal portion inserted into the internal space of the holder through a side wall opening provided on a peripheral wall portion of the holder, and capable of removing the protective cap from the container body using the cap removal portion while the cap removal portion is engaged with the protective cap within the internal space; and a disinfecting member having a cap disinfecting portion located within the internal space, capable of disinfecting the sealing portion by bringing the cap disinfecting portion into contact with the sealing portion within the internal space after the protective cap is removed from the container body.

[0008] According to this medical tool, the protective cap can be removed and the sealing portion can be disinfected easily and reliably using a single medical tool.

[0009] (2) In the medical tool described in (1) above, the operating member has a gripping portion that protrudes from the side wall opening to the outside of the holder and is gripped by a user, and the cap removal portion has a cap engaging portion that can engage with the protective cap, and the protective cap may be removed from the container body by moving the operating member relative to the holder so that the gripping portion and the cap engaging portion are displaced in opposite directions with the side wall opening as a fulcrum.

[0010] With this configuration, the protective cap can be easily removed by operating the operating member like a lever.

[0011] (3) In the medical device described in (1) above, the cap removal portion may have a pair of expandable cap holding portions, and the protective cap may be separated and removed from the container body by expanding the pair of cap holding portions while the protective cap is held by the pair of cap holding portions.

[0012] This configuration allows the protective cap to be easily removed without moving the entire operating member.

[0013] (4) In the medical device according to any one of (1) to (3), the disinfecting member may be movable relative to the holder in the axial direction of the holder. With this configuration, the disinfecting member can be moved relative to the holder to easily disinfect the sealing portion.

[0014] (5) In the medical tool described in any one of (1) to (4) above, the disinfecting member may have an operating shaft portion that is inserted into a guide hole provided in the holder and protrudes outside the holder.

[0015] With this configuration, the user can easily operate the disinfecting member by gripping the operating shaft.

[0016] (6) In the medical device described in any one of (1) to (5) above, the holder may have a cap recovery section capable of recovering the protective cap removed from the container body, and the cap recovery section may be provided in a position that does not interfere with contact between the cap disinfection section and the sealing section.

[0017] This configuration allows the disinfection of the sealing portion to be carried out quickly after the protective cap is removed.

[0018] (7) In the medical device described in any one of (1) to (6) above, the holder has a storage area capable of storing at least the cap removal portion of the operating member after the protective cap is removed from the container body, and the storage area may be located in a position that does not interfere with contact between the cap disinfection portion and the sealing portion.

[0019] This configuration allows the disinfection of the sealing portion to be carried out quickly after the protective cap is removed.

[0020] According to the present disclosure, by providing a cap removal portion that is inserted into the internal space of the holder and a disinfection member that can disinfect the sealing portion within the internal space using a cap disinfection portion after the protective cap is removed, it is possible to easily and reliably remove the protective cap and disinfect the sealing portion using a single medical tool.

[0022] As shown in Fig. 1, the medical tool 10 according to this embodiment is used to remove a protective cap 14 from a container body 121 of a medical container 12 and disinfect a sealing portion 123 provided on an opening 122 of the container body 121. The medical container 12 is used to collect a sample (not shown) such as blood. The sample may be a pharmaceutical product other than a blood product. The sample may also be a liquid sample other than a pharmaceutical product.

[0023] As shown in Figure 2, the medical container 12 includes a container body 121, a protective cap 14 attached to the container body 121, and a neck portion 124 that tapers radially inward below the protective cap 14. The container body 121 is formed in a cylindrical shape and is capable of containing a collection target. The end of the container body 121 includes a lid member 125 that surrounds the outer periphery, an opening 122 through which the collection target is introduced, and a sealing portion 123 that seals the opening 122. The opening 122 and the sealing portion 123 are provided inside the lid member 125. In the axial direction of the medical container 12, the end of the lid member 125 and the end of the sealing portion 123 are at approximately the same position.

[0024] The protective cap 14 is provided at the end of the container body 121 in the axial direction of the medical container 12. The protective cap 14 covers the end of the sealing portion 123 and the end of the lid member 125. The protective cap 14 is attached to cover the surface of the sealing portion 123, which has been sterilized in advance. The outer periphery of the protective cap 14 protrudes radially outward from the lid member 125. The open end 141 of the protective cap 14 is positioned radially outward from the outer periphery of the lid member 125. When storing a collection target in the medical container 12, the protective cap 14 is removed from the container body 121 and used with the sealing portion 123 and lid member 125 exposed (see FIG. 3 ). The protective cap 14 is removed from the container body 121 in the axial direction of the container body 121, away from the end of the container body 121.

[0025] As shown in FIG. 1 , the medical tool 10 includes a holder 16 , an operating member 18 , and a disinfecting member 20 .

[0026] The holder 16 is formed so as to be able to accommodate a portion of the medical container 12. The holder 16 is formed in a cylindrical shape. The holder 16 has a first end 161 provided at one axial end of the holder 16 in the axial direction, and a second end 162 provided at the other axial end. The medical jig 10 is used, for example, with the first end 161 facing downward. Note that the use direction of the medical jig 10 is not limited to when the first end 161 is used facing downward.

[0027] The holder 16 includes a peripheral wall portion 22, an internal space 24 provided inside the peripheral wall portion 22, an end opening 26 provided at the first end portion 161, and a side wall opening 28. The end opening 26 opens in the axial direction of the holder 16.

[0028] The peripheral wall portion 22 constitutes the outer periphery of the holder 16. When viewed from the axial direction of the holder 16, the peripheral wall portion 22 is formed in a substantially circular shape. The peripheral wall portion 22 extends along the axial direction of the holder 16. The inner periphery of the peripheral wall portion 22 is formed so as to be able to hold the outer periphery of the container body 121.

[0029] The internal space 24 extends along the axial direction of the holder 16. The internal space 24 is surrounded by the peripheral wall portion 22 and the second end portion 162. A portion of the medical container 12 is accommodated in the internal space 24. The medical container 12 is inserted into the internal space 24 through the end opening 26. Specifically, the internal space 24 can accommodate a portion of the container body 121 of the medical container 12 and the protective cap 14. Note that the internal space 24 of the holder 16 may also be able to accommodate the entire medical container 12.

[0030] The side wall opening 28 is formed in the peripheral wall 22 and penetrates it in the radial direction. The side wall opening 28 is located approximately in the center of the holder 16 in the axial direction, and is formed with a predetermined width along the circumferential direction of the peripheral wall 22. When the medical container 12 is housed in the internal space 24 of the holder 16, the side wall opening 28 is formed at a position in the axial direction of the holder 16 that is near the protective cap 14.

[0031] The operating member 18 is provided in the sidewall opening 28 of the holder 16. The operating member 18 extends in a direction substantially perpendicular to the axial direction of the holder 16. The operating member 18 has a cap removal portion 181, a grip portion 182, and an intermediate portion 183.

[0032] 2, the cap removal portion 181 is provided at one end of the operating member 18 and is disposed in the internal space 24 of the holder 16. The cap removal portion 181 has a cap engagement portion 30 that can engage with the protective cap 14 of the medical container 12. The cap engagement portion 30 is provided at the tip of the cap removal portion 181.

[0033] The cap engaging portion 30 includes a first engaging portion 301 and a second engaging portion 302. The first engaging portion 301 extends toward the first end 161 perpendicular to the extending direction of the operating member 18. The first engaging portion 301 faces the outer peripheral surface of the protective cap 14 of the medical container 12. The second engaging portion 302 is provided at the end of the first engaging portion 301. The second engaging portion 302 extends in a direction perpendicular to the first engaging portion 301. The extending direction of the second engaging portion 302 is the extending direction of the operating member 18. The second engaging portion 302 is disposed below the open end 141 of the protective cap 14. The second engaging portion 302 is provided so as to be able to engage with the open end 141 of the protective cap 14.

[0034] 1, the grip portion 182 is provided at the other end of the operating member 18 and protrudes from the side wall opening 28 to the outside of the holder 16. The grip portion 182 is formed so that it can be gripped by the user.

[0035] The intermediate portion 183 is provided between the cap removal portion 181 and the grip portion 182 in the extension direction of the operating member 18. The operating member 18 is supported on the holder 16 by the intermediate portion 183. The operating member 18 is supported so as to be tiltable relative to the holder 16, with the intermediate portion 183 supported on the side wall opening 28 as a fulcrum. The operating member 18 is supported so that the grip portion 182 and the cap engagement portion 30 are displaced in opposite directions with the intermediate portion 183 (side wall opening 28) as a fulcrum. Specifically, as shown in FIG. 3 , when the user presses the grip portion 182 downward, the cap engagement portion 30 is displaced upward, which is the opposite direction, within the internal space 24, with the intermediate portion 183 as a fulcrum.

[0036] As shown in FIG. 1, the holder 16 further includes a cap collection section 32 and a storage area 34 .

[0037] The cap retrieval portion 32 is formed to be able to retrieve the protective cap 14 removed from the medical container 12 (see FIG. 4 ). The cap retrieval portion 32 is formed adjacent to the side wall opening 28 and adjacent to the middle portion 183 of the operating member 18. The cap retrieval portion 32 is provided between the side wall opening 28 and the first end 161. When the medical container 12 is housed in the internal space 24, the cap retrieval portion 32 is provided at a position lower than the protective cap 14 of the medical container 12. The cap retrieval portion 32 is formed by expanding a portion of the peripheral wall portion 22 radially outward. The cap retrieval portion 32 extends along the axial direction of the holder 16 and has a bottom portion 321 at its end.

[0038] The holder 16 has a partition wall portion 322 radially inward of the cap recovery portion 32. The partition wall portion 322 radially separates at least the lower portion of the cap recovery portion 32 from the internal space 24. The upper portion of the partition wall portion 322 has an inclined portion 323 that slopes upward and radially inward. The inclined portion 323 contacts the outer peripheral surface of the medical container 12. The inclined portion 323 determines the axial position of the medical container 12 in the holder 16. Note that the partition wall portion 322 does not necessarily have to include the inclined portion 323. The cap recovery portion 32 is formed to a size capable of accommodating the protective cap 14. Specifically, the cap recovery portion 32 is formed to be larger than the axial thickness and diameter of the protective cap 14. Note that the cap recovery portion 32 may have a space capable of accommodating one protective cap 14 or multiple protective caps 14.

[0039] The cap recovery part 32 is provided at a position where it does not interfere with the movement of the disinfecting member 20 when the disinfecting member 20 moves axially in the internal space 24 of the holder 16 (see FIG. 5). That is, in the holder 16, the cap recovery part 32 is disposed radially outward with respect to the movement trajectory of the disinfecting member 20.

[0040] The accommodating area 34 is formed to be able to accommodate at least a portion of the operating member 18 after the protective cap 14 is removed from the medical container 12 (see FIG. 4 ). The accommodating area 34 is provided adjacent to the side wall opening 28 and adjacent to the middle portion 183 of the operating member 18. The accommodating area 34 is provided between the side wall opening 28 and the second end 162 and extends along the axial direction of the holder 16. The accommodating area 34 is formed by expanding a portion of the peripheral wall portion 22 radially outward. The accommodating area 34 has a space capable of accommodating at least the cap engaging portion 30 of the operating member 18.

[0041] The holder 16 has a separation wall 36 between the storage area 34 and the internal space 24. The separation wall 36 protrudes radially inward from the inner circumferential surface of the peripheral wall portion 22. The separation wall 36 extends along the axial direction of the holder 16. The separation wall 36 extends from the second end 162 to the side wall opening 28. The storage area 34 may be capable of storing only a portion of the operating member 18, or may be capable of storing the entire operating member 18 including the grip portion 182. The cap recovery portion 32 and the storage area 34 face each other in the axial direction of the holder 16. The cap recovery portion 32 and the storage area 34 may be located at different positions in the circumferential direction of the holder 16.

[0042] The accommodation area 34 is provided at a position that does not interfere with the movement of the disinfecting member 20, which is movable in the axial direction, in the internal space 24 of the holder 16 (see FIG. 5). That is, in the holder 16, the accommodation area 34 is disposed radially outward with respect to the movement trajectory of the disinfecting member 20.

[0043] The disinfecting member 20 is provided so as to be able to disinfect the sealing portion 123 of the medical container 12 after the protective cap 14 is removed (see FIG. 5). The disinfecting member 20 is disposed closer to the second end 162 of the holder 16 than the operating member 18. The disinfecting member 20 is provided so as to be able to move relative to the holder 16 in the axial direction of the holder 16. The disinfecting member 20 includes a cap disinfecting portion 201 and an operating shaft portion 202 that supports the cap disinfecting portion 201.

[0044] The cap disinfection unit 201 is provided in the internal space 24. The cap disinfection unit 201 faces the end of the medical container 12 in the axial direction of the holder 16. The cap disinfection unit 201 includes a base member 38 and a disinfection unit 40. The base member 38 is formed in a plate shape, and the disinfection unit 40 is provided on a first surface 381. The disinfection unit 40 is impregnated with a disinfectant. The disinfection unit 40 is made of, for example, gauze or cotton impregnated with a disinfectant. The diameter of the disinfection unit 40 is at least larger than the diameter of the sealing portion 123 of the medical container 12. The disinfection unit 40 may be made of multiple sheets of material stacked in the thickness direction. Note that the disinfection unit 40 is not limited to being made of multiple sheets of material. For example, the disinfection unit 40 may be made of a single member other than a sheet material.

[0045] The operating shaft 202 is connected to the center of the second surface 382 of the base member 38. The operating shaft 202 extends in a direction perpendicular to the base member 38. The operating shaft 202 is inserted into a guide hole 163 provided in the second end 162 of the holder 16. The guide hole 163 is formed on the axis of the holder 16 and penetrates the holder 16 in the axial direction. The operating shaft 202 protrudes to the outside of the holder 16 through the guide hole 163. A user can move the disinfection unit 40 along the axial direction within the internal space 24 by grasping the operating shaft 202 and moving it axially. The disinfection member 20 is guided in the axial direction of the holder 16 along the guide hole 163.

[0046] When the disinfecting member 20 moves along the axial direction of the holder 16, the cap collecting section 32 and the storage area 34 of the holder 16 are disposed radially outward from the cap disinfecting section 201. In other words, the cap collecting section 32 and the storage area 34 are provided at positions that do not prevent contact between the cap disinfecting section 201 and the sealing section 123.

[0047] Next, a case will be described in which the sealing portion 123 is disinfected after the protective cap 14 of the medical container 12 is removed using the medical tool 10. Here, a case will be described in which the first end 161 of the holder 16 is positioned downward and the second end 162 is positioned upward.

[0048] In the initial state of the medical tool 10 shown in FIG. 1 , the disinfecting member 20 is positioned relatively above the holder 16. The end of the medical container 12 is inserted into the internal space 24 of the holder 16 through the end opening 26. The container body 121 of the medical container 12 is held by the inner circumferential surface of the peripheral wall portion 22. The protective cap 14 contacts the cap removal portion 181 of the operating member 18. The protective cap 14 contacts the cap removal portion 181, thereby holding the medical container 12 in a predetermined position relative to the holder 16. The tip of the cap removal portion 181 may be provided with a convex contact portion that can contact the inner circumferential surface of the peripheral wall portion 22. The contact of the contact portion with the inner circumferential surface of the peripheral wall portion 22 positions the operating member 18 in the radial direction of the holder 16.

[0049] By accommodating the medical container 12 at a predetermined position in the internal space 24 of the holder 16, the open end 141 of the protective cap 14 climbs over the second engaging portion 302 of the cap engaging portion 30 and is positioned above the second engaging portion 302, as shown in Figure 2. The first engaging portion 301 is positioned radially outward of the protective cap 14. This places the protective cap 14 in a state of being engaged with the cap engaging portion 30 of the cap removal portion 181.

[0050] 3, when the user presses the grip portion 182 downward, the operating member 18 tilts with the intermediate portion 183 as a fulcrum so that the cap removal portion 181 (cap engagement portion 30) rises toward the second end portion 162 in the internal space 24. In other words, when the grip portion 182 is pressed, the grip portion 182 and the cap engagement portion 30 of the operating member 18 are displaced in opposite directions with the intermediate portion 183 as a fulcrum.

[0051] As the operating member 18 tilts around the intermediate portion 183 as a fulcrum, the cap removal portion 181 is displaced in a direction away from the container body 121, and the second engagement portion 302 pushes the open end 141 of the protective cap 14 upward. The protective cap 14 pushed by the second engagement portion 302 is removed upward from the lid member 125 and container body 121. Specifically, the cap engagement portion 30 removes the protective cap 14 obliquely toward the side wall opening 28. This exposes the lid member 125 and sealing portion 123 of the medical container 12 in the internal space 24 of the holder 16. Removal of the protective cap 14 by the cap removal portion 181 is completed.

[0052] As shown in FIG. 4 , the removed protective cap 14 moves along the operating member 18 toward the side wall opening 28, thereby disengaging from the cap engaging portion 30. The protective cap 14 moves along the operating member 18 toward the side wall opening 28. The protective cap 14 then contacts the peripheral wall portion 22 below the side wall opening 28, and then descends along the peripheral wall portion 22 to be housed in the cap retrieval portion 32. In the cap retrieval portion 32, the protective cap 14 is housed in a state rotated approximately 90° from the state in which it was attached to the medical container 12 (a state in which the axial direction of the protective cap 14 is perpendicular to the axial direction of the holder 16). The partition portion 322 prevents the protective cap 14 from moving toward the internal space 24, and the protective cap 14 is held in the cap retrieval portion 32.

[0053] Next, before disinfecting the sealing portion 123 of the medical container 12 with the disinfecting member 20, an operation (hereinafter referred to as the “storing operation”) is performed to store at least a portion of the operating member 18 in the storage area 34 of the holder 16. In the storing operation, the user inserts the cap removal portion 181 of the operating member 18 into the storage area 34.

[0054] In this case, the operating member 18 moves along the separation wall 36 toward the second end 162, and at least a portion of the operating member 18 (the cap removal portion 181 and the intermediate portion 183) is accommodated in the accommodation region 34. The remaining portion of the operating member 18, including the grip portion 182, is exposed to the outside of the holder 16 through the side wall opening 28. For example, by appropriately setting the length of the operating member 18 and the volume of the accommodation region 34, the entire operating member 18 may be accommodated in the accommodation region 34.

[0055] When the operating member 18 is removed from the holder 16, the disinfecting member 20 and the sealing portion 123 of the medical container 12 face each other in the axial direction of the holder 16.

[0056] Next, the disinfecting member 20 disinfects the sealing portion 123 of the medical container 12. Specifically, as shown in FIG. 5 , the user grips the operating shaft 202 and moves the disinfecting member 20 toward the medical container 12. The disinfecting portion 40 of the disinfecting member 20 contacts the end surface of the medical container 12, including the sealing portion 123. The disinfectant in the disinfecting portion 40 disinfects the end of the medical container 12, including the sealing portion 123, within the internal space 24. At this time, the removed protective cap 14 is stored in the cap recovery portion 32, and the removed operating member 18 is stored in the storage area 34. Therefore, the protective cap 14 and the operating member 18 do not interfere with the movement of the disinfecting member 20 within the internal space 24.

[0057] After the sterilization or disinfection of the sealing portion 123 of the medical container 12 is completed, the disinfecting member 20 is moved in a direction away from the medical container 12, as shown in FIG. 6 . If the disinfecting unit 40 is made of multiple sheets, when the disinfecting unit 40 is moved away from the end of the medical container 12, the sheet material arranged at the bottom of the disinfecting unit 40 adheres to the end of the medical container 12 and is peeled off from the disinfecting unit 40. By peeling off the sheet material, a new sheet material is exposed in the disinfecting unit 40. The disinfecting unit 40 with the new sheet material exposed is used to disinfect the next medical container 12. In other words, the disinfecting unit 40, which is made up of multiple stacked sheet materials, makes it possible to disinfect multiple medical containers 12 using a single medical jig 10.

[0058] Then, by moving the medical container 12 relative to the holder 16 in the axial direction, the medical container 12 is removed from the internal space 24 of the holder 16 to the outside.

[0059] This embodiment has the following advantages.

[0060] 1, the medical device 10 includes a cap removal part 181 that is inserted into the internal space 24 of the holder 16, and a disinfecting member 20 that can disinfect the sealing part 123 within the internal space 24 using a cap disinfecting part 201 after the protective cap 14 is removed. This allows the protective cap 14 to be removed and the sealing part 123 to be disinfected easily and reliably using a single medical device 10.

[0061] 3, the operating member 18 has a gripping portion 182 that protrudes from the sidewall opening 28 of the holder 16 to the outside of the holder 16 and is gripped by a user. The cap removal portion 181 has a cap engaging portion 30 that can engage with the protective cap 14. The protective cap 14 can be removed from the container body 121 by moving the operating member 18 with the sidewall opening 28 of the holder 16 as a fulcrum. With this configuration, the protective cap 14 can be easily removed by operating the operating member 18 like a lever.

[0062] 5, the disinfecting member 20 is movable relative to the holder 16 in the axial direction of the holder 16. With this configuration, by moving the disinfecting member 20 relative to the holder 16, the sealing portion 123 of the medical container 12 can be easily disinfected.

[0063] The disinfecting member 20 has an operating shaft 202 that is inserted into a guide hole 163 provided in the holder 16 and protrudes outside the holder 16. With this configuration, the user can easily operate the disinfecting member 20 by gripping the operating shaft 202.

[0064] The holder 16 has a cap recovery unit 32 that can recover the protective cap 14 removed from the container body 121. The cap recovery unit 32 is provided in a position that does not prevent contact between the cap disinfection unit 201 of the disinfection member 20 and the sealing unit 123 of the medical container 12. With this configuration, after the protective cap 14 is removed, it is possible to quickly move on to the disinfection work of the sealing unit 123.

[0065] The holder 16 has a storage area 34 that can store at least the cap removal portion 181 of the operating member 18 after the protective cap 14 is removed from the container body 121. The storage area 34 is provided in a position that does not prevent contact between the cap disinfection portion 201 of the disinfection member 20 and the sealing portion 123 of the medical container 12. With this configuration, after the protective cap 14 is removed from the container body 121, it is possible to quickly move on to the disinfection work of the sealing portion 123 of the medical container 12.

[0066] As shown in FIG. 7, a medical tool 10A according to a modified example includes a holder 16A and an operating member 18A.

[0067] The holder 16A has a storage portion 50 on the outer circumferential side of the peripheral wall portion 22. The storage portion 50 is formed to be able to store the operating member 18A. The storage portion 50 expands radially outward from the peripheral wall portion 22 of the holder 16A and extends axially. The storage portion 50 includes a storage space 52 capable of storing a portion of the operating member 18A, and a cap recovery portion 32 capable of storing the protective cap 14. The storage space 52 is provided on the sidewall opening 28 side of the cap recovery portion 32.

[0068] The storage section 50 further has a notch 54. The notch 54 is cut downward from the side wall opening 28. The notch 54 is located above the cap recovery section 32. The notch 54 is formed so that the intermediate section 183 of the operating member 18A can be inserted into the notch 54. The operating member 18A has a cap removal section 181A that can engage with and remove the protective cap 14 of the medical container 12. The cap removal section 181A is covered by the peripheral wall section 22 of the holder 16A. In other words, the radially outward side of the cap removal section 181A is covered by the peripheral wall section 22.

[0069] After the protective cap 14 of the medical container 12 is removed by the cap removal portion 181A of the operating member 18A, the gripping portion 182 of the operating member 18A is grasped and moved toward the notch 54. At this time, as shown in FIG. 8 , the operating member 18A is rotated about a center line along the extension direction of the operating member 18A so that the thickness direction of the operating member 18A, which is perpendicular to the extension direction, is approximately parallel to the axial direction of the holder 16A. Then, the middle portion 183 of the operating member 18A is inserted into the notch 54, and the cap removal portion 181A is accommodated in the accommodation space 52. This holds the operating member 18A in the accommodation portion 50 via the notch 54. After the protective cap 14B is removed from the container body 121, the sealing portion 123 is disinfected using the disinfectant 20.

[0070] In the medical jig 10 or 10A described above, an operating member 18B according to a modified example shown in Figures 9A and 9B may be used instead of the operating member 18 or 18A. As shown in Figure 9A, the operating member 18B has a gripping portion 182B and a cap removal portion 181B.

[0071] The cap removal portion 181B has a pair of expandable cap holding portions 601, 602. The pair of cap holding portions 601, 602 are provided so as to be openable and closable with the tip of the grip portion 182B as a fulcrum. The pair of cap holding portions 601, 602 are arranged symmetrically with respect to a center line along the extension direction of the operating member 18B. Each of the pair of cap holding portions 601, 602 is formed in an arc shape. The inner surface of each cap holding portion 601, 602 has a holding surface 62 capable of holding the outer peripheral surface of the protective cap 14B. Note that when the operating member 18B is employed, the holder 16 ( FIG. 1 ) or the holder 16A ( FIG. 7 ) is configured to accommodate, for example, the pair of cap holding portions 601, 602.

[0072] Next, the case where the protective cap 14B is removed by the cap removal part 181B will be described.

[0073] First, the pair of cap holders 601, 602 are opened relative to each other (see FIG. 9B ) with the tip of the gripping portion 182B as a fulcrum, and are positioned radially outward of the protective cap 14B of the medical container 12. Then, by closing the pair of cap holders 601, 602, the outer peripheral surface of the protective cap 14B is sandwiched and covered by the pair of cap holders 601, 602. The outer peripheral surface of the protective cap 14B is held by each holding surface 62 of the pair of cap holders 601, 602.

[0074] The protective cap 14B is opened by moving the pair of cap holders 601, 602 away from each other while the pair of cap holders 601, 602 hold the outer peripheral surface of the protective cap 14B. Because the protective cap 14B is held by the pair of cap holders 601, 602, the pair of cap holders 601, 602 pull the protective cap 14B toward each other in a direction intersecting the extension direction of the operating member 18B. As shown in FIG. 9B , when the pair of cap holders 601, 602 open, the protective cap 14B splits into two at approximately the center of the protective cap 14B.

[0075] As a result, the protective cap 14B is removed from the container body 121 of the medical container 12, and the sealing portion 123 is exposed to the outside. Preferably, the protective cap 14B has a breaking line L with multiple notches. This makes it easy to separate the protective cap 14B starting from the breaking line L. After the protective cap 14B is removed from the container body 121, the sealing portion 123 is disinfected using the disinfectant 20 (FIG. 1).

[0076] The modified example has the following effects.

[0077] 9B , while the protective cap 14B is held by the pair of cap holders 601, 602, the pair of cap holders 601, 602 are spread apart. This separates the protective cap 14B, allowing it to be removed from the medical container 12. With this configuration, the protective cap 14B can be easily removed without moving the entire operating member 18B.
