Description

容器container
　この発明は、容器に関する。 This invention relates to a container.
　病院などの医療機関においては、バイアル等の薬剤容器に入った乾燥薬剤を、蒸留水、生理食塩水、ブドウ糖液、その他の溶解液に溶解して液状薬品を調整し、点滴注射などにこの液状薬品を用いている。 In medical institutions such as hospitals, dry drugs contained in drug containers such as vials are dissolved in distilled water, physiological saline, glucose solution, and other dissolved solutions to adjust liquid chemicals, and this liquid is used for infusion injections. Uses chemicals.
　このような液状薬品を簡便に調整できるように、乾燥薬剤を収容した薬剤容器を、溶解液を収納した輸液容器に直列状に連結し、使用時にこれら二つの容器の内部を連通するようにした医療用容器が提案されている（たとえば、国際公開第２０１３／１７５９７０号（特許文献１）参照）。 In order to be able to easily adjust such liquid chemicals, a drug container containing a dry drug was connected in series to an infusion container containing a dissolved solution, and the inside of these two containers communicated with each other during use. A medical container has been proposed (see, for example, International Publication No. 2013/175970 (Patent Document 1)).
国際公開第２０１３／１７５９７０号International Publication No. 2013/175970
　輸液容器内の液体が排出されるとき、輸液容器がねじれるような変形をすると液体が輸液容器内に残存する場合がある。また、滅菌時にも膨張等による変形が起こる場合がある。 When the liquid in the infusion container is discharged, the liquid may remain in the infusion container if the infusion container is deformed to be twisted. Further, deformation due to expansion or the like may occur during sterilization.
　本発明の目的は、変形量を制限できる容器を提供することである。 An object of the present invention is to provide a container that can limit the amount of deformation.
　本発明の容器は、膜部を一端に備える。膜部には孔が形成される。容器の一端と反対側の他端には、液体を排出する液体取出口が形成される。容器は、箱状部をさらに備える。膜部の中心と液体取出口の中心との両方を通る直線の延びる方向を第一の方向とし、箱状部は、第一の方向に直交する断面が略矩形の形状を有する。箱状部には略矩形の角部に、第一の方向に平行に延びる溝が形成されている。 The container of the present invention has a membrane part at one end. A hole is formed in the film part. A liquid outlet for discharging liquid is formed at the other end opposite to the one end of the container. The container further includes a box-shaped portion. A direction in which a straight line passing through both the center of the membrane portion and the center of the liquid outlet extends is a first direction, and the box-like portion has a substantially rectangular shape in cross section perpendicular to the first direction. The box-shaped portion is formed with a groove extending in parallel with the first direction at a corner portion of a substantially rectangular shape.
　上記の容器によれば、略矩形の角部に形成される溝により容器の剛性が大きくなっているので、液体が排出されるときに、容器の変形量を制限することができる。 According to the above container, since the rigidity of the container is increased by the groove formed in the substantially rectangular corner, the deformation amount of the container can be limited when the liquid is discharged.
　上記の容器において、箱状部は、略矩形の角部に畝部を有する。畝部は、第一の方向と平行に延び、箱状部の内部に突き出る。畝部によって、容器の剛性がより大きくなるので、容器の変形量を制限することができる。 In the above container, the box-shaped portion has a flange at a substantially rectangular corner. The collar portion extends in parallel with the first direction and protrudes into the box-shaped portion. Since the rigidity of the container is further increased by the flange portion, the deformation amount of the container can be limited.
　上記の容器において、箱状部は、第一の方向に延びる壁面部を有する。溝は、壁面部の第一の方向の両端に亘って延びる。溝が広範囲に亘って延びることによって、容器の剛性がより大きくなるので、変形量を制限することができる。 In the above container, the box-shaped portion has a wall surface portion extending in the first direction. The groove extends across both ends of the wall surface in the first direction. Since the rigidity of the container is increased by extending the groove over a wide range, the deformation amount can be limited.
　上記の容器において、溝は、略矩形の角部の全てに形成される。溝の数が多くなることによって、容器の剛性がより大きくなるので、容器の変形量を制限することができる。 In the above container, the groove is formed in all of the corners of the substantially rectangular shape. Since the rigidity of the container is increased by increasing the number of grooves, the deformation amount of the container can be limited.
　上記の容器において、箱状部の壁厚は、溝の深さよりも小さい。壁厚が薄い容器でも、溝により容器の剛性が大きくなるので、容器の変形量を制限することができる。 In the above container, the wall thickness of the box-shaped part is smaller than the depth of the groove. Even in a container having a thin wall thickness, the rigidity of the container is increased by the groove, so that the deformation amount of the container can be limited.
　本発明によると、変形量を制限できる容器を実現することができる。 According to the present invention, a container capable of limiting the amount of deformation can be realized.

　実施の形態の医療用容器１および医療用容器１に用いられる輸液容器１００の構成および作用効果についてまとめて説明すると、以下の通りである。なお、実施の形態の構成に参照番号を付すが、これは一例である。 It is as follows when the structure and the effect of the infusion container 100 used for the medical container 1 and the medical container 1 of embodiment are demonstrated collectively. In addition, although a reference number is attached | subjected to the structure of embodiment, this is an example.
　本実施の形態の医療用容器１は、図１に示すように、輸液容器１００と、連結部材３００とを備えている。輸液容器１００は、膜部４を上端に有する。輸液容器１００の下端には、水剤取出口６が形成される。輸液容器１００は、箱状部３をさらに有する。膜部４の中心と水剤取出口６の中心との両方を通る直線の延びる方向を第一の方向ＤＲ１として、箱状部３は、第一の方向ＤＲ１に直交する断面が略矩形の形状を有する。箱状部３は、略矩形の断面の角部１１に、第一の方向ＤＲ１に平行に延びる溝１２が形成されている。これにより、輸液容器１００の剛性が大きくなるので、液体が排出されるときに、輸液容器１００の変形量を制限することができる。これによって、液体が輸液容器１００内に残存しにくくなるため、輸液容器１００内の液体を最後まで使用することができ、経済性が高くなる。また、輸液容器１００の剛性が大きくなるので、輸液容器１００を高温高圧蒸気による滅菌処理をした際に、熱応力による輸液容器１００の変形を抑制することができる。 The medical container 1 according to the present embodiment includes an infusion container 100 and a connecting member 300 as shown in FIG. The infusion container 100 has the membrane part 4 at the upper end. A liquid medicine outlet 6 is formed at the lower end of the infusion container 100. The infusion container 100 further has a box-shaped part 3. The direction in which a straight line passing through both the center of the membrane part 4 and the center of the liquid medicine outlet 6 extends is defined as a first direction DR1, and the box-shaped part 3 has a substantially rectangular cross section perpendicular to the first direction DR1 Have In the box-shaped part 3, a groove 12 extending in parallel with the first direction DR1 is formed in a corner part 11 of a substantially rectangular cross section. Thereby, since the rigidity of the infusion container 100 is increased, the deformation amount of the infusion container 100 can be limited when the liquid is discharged. This makes it difficult for the liquid to remain in the infusion container 100, so that the liquid in the infusion container 100 can be used to the end, and the economy is increased. Further, since the rigidity of the infusion container 100 is increased, deformation of the infusion container 100 due to thermal stress can be suppressed when the infusion container 100 is sterilized with high-temperature and high-pressure steam.
　図７に示すように、箱状部３は、第一の方向ＤＲ１に直交する略矩形の断面の角部１１に畝部１３を有する。畝部１３は、第一の方向ＤＲ１と平行に延び、箱状部３の内部に突き出る。畝部１３によって、輸液容器１００の剛性がより大きくなるので、輸液容器１００の変形量を制限することができる。 As shown in FIG. 7, the box-shaped portion 3 has a flange portion 13 at a corner portion 11 of a substantially rectangular cross section orthogonal to the first direction DR1. The collar portion 13 extends in parallel with the first direction DR1 and protrudes into the box-shaped portion 3. Since the rigidity of the infusion container 100 is further increased by the collar portion 13, the deformation amount of the infusion container 100 can be limited.
　図２に示すように、箱状部３は、第一の方向ＤＲ１に延びる壁面部８を有する。壁面部８は、一対の第一壁面部８ａと一対の第二壁面部８ｂから構成される。溝１２は、壁面部８の第一の方向の両端に亘って延びる。溝１２が広範囲に亘って延びることによって、輸液容器の剛性がより大きくなるので、変形量を制限することができる。 As shown in FIG. 2, the box-shaped part 3 has a wall surface part 8 extending in the first direction DR1. The wall surface portion 8 includes a pair of first wall surface portions 8a and a pair of second wall surface portions 8b. The groove 12 extends across both ends of the wall surface portion 8 in the first direction. Since the rigidity of the infusion container is further increased by extending the groove 12 over a wide range, the amount of deformation can be limited.
　溝１２は、略矩形の角部１１の全てに形成される。溝１２の数が多くなることによって、輸液容器１００の剛性がより大きくなるので、輸液容器の変形量を制限することができる。 The grooves 12 are formed in all of the substantially rectangular corners 11. Since the rigidity of the infusion container 100 is increased by increasing the number of the grooves 12, the amount of deformation of the infusion container can be limited.
　図６に示すように、角部１１の壁厚ｔは、溝深さｄよりも小さい。壁厚が薄い輸液容器１００でも、溝１２により輸液容器１００の剛性が大きくなるので、輸液容器１００の変形量を制限することができる。 As shown in FIG. 6, the wall thickness t of the corner 11 is smaller than the groove depth d. Even in the infusion container 100 having a thin wall thickness, the rigidity of the infusion container 100 is increased by the grooves 12, and therefore, the deformation amount of the infusion container 100 can be limited.
　本実施の形態の輸液容器１００は、図１に示すように、医療用容器１に用いられる。医療用容器１は、輸液容器１００と、連結部材３００とを備えている。輸液容器１００は、膜部４を上端に有する。輸液容器１００の下端には、水剤取出口６が形成される。輸液容器１００は、箱状部３をさらに有する。膜部４の中心と水剤取出口６の中心との両方を通る直線の延びる方向を第一の方向ＤＲ１として、箱状部３は、第一の方向ＤＲ１に直交する断面が略矩形の形状を有する。箱状部３の略矩形の断面の角部１１に、第一の方向ＤＲ１に平行に延びる溝１２が形成されている。これにより、輸液容器１００の剛性が大きくなるので、液体が排出されるときに、輸液容器１００の変形量を制限することができる。 The infusion container 100 of the present embodiment is used for a medical container 1 as shown in FIG. The medical container 1 includes an infusion container 100 and a connecting member 300. The infusion container 100 has the membrane part 4 at the upper end. A liquid medicine outlet 6 is formed at the lower end of the infusion container 100. The infusion container 100 further has a box-shaped part 3. The direction in which a straight line passing through both the center of the membrane part 4 and the center of the liquid medicine outlet 6 extends is defined as a first direction DR1, and the box-shaped part 3 has a substantially rectangular cross section perpendicular to the first direction DR1. Have Grooves 12 extending in parallel with the first direction DR1 are formed in corner portions 11 of the substantially rectangular cross section of the box-shaped portion 3. Thereby, since the rigidity of the infusion container 100 is increased, the deformation amount of the infusion container 100 can be limited when the liquid is discharged.
　変形例として、膜部４および水剤取出口６は、円形状でなくてもよい。膜部４および水剤取出口６が円形状以外である場合、それぞれの形状の重心を中心として定義する。例えば、膜部４および水剤取出口６の形状が長方形である場合、長方形の対角線の交点が中心である。 As a modification, the membrane part 4 and the liquid medicine outlet 6 do not have to be circular. In the case where the film part 4 and the liquid medicine outlet 6 are other than circular, the center of gravity of each shape is defined as the center. For example, when the shape of the film part 4 and the liquid medicine outlet 6 is a rectangle, the intersection of the diagonal lines of the rectangle is the center.
　本発明の実施例として、溝が形成されていない輸液容器と溝１２が形成されている輸液容器１００のそれぞれについて、高圧蒸気滅菌処理（１２１℃で２０分間）前後における輸液容器の寸法を測定した。下記に測定結果を示す。 As an example of the present invention, the dimensions of the infusion container before and after high-pressure steam sterilization (at 121 ° C. for 20 minutes) were measured for each of the infusion container in which the groove was not formed and the infusion container 100 in which the groove 12 was formed. . The measurement results are shown below.

Figure JPOXMLDOC01-appb-T000001
　短辺は、図５に示すａであり、長辺は、図５に示すｂである。キーエンス社製ＬＳ－９１２０Ｍを用いて短辺ａ、長辺ｂを測定した。カバー部材２００を下にして測定器に輸液容器１００を設置し、高さ７０ｍｍの位置における輸液容器１００の短辺ａおよび長辺ｂを１か所ずつ測定した。溝深さｄは、オリンパス社製ＳＴＭ７を用いて測定した。略矩形箱状の輸液容器１００の４角の溝深さｄを１か所ずつ測定した。表１は、１０個の輸液容器において、短辺ａ、長辺ｂ、溝深さｄそれぞれの寸法測定結果の最大値を示している。なお、高圧蒸気滅菌処理前の輸液容器の溝深さｄは、溝が形成されていない輸液容器と溝１２が形成されている輸液容器１００のどちらも２．２０［ｍｍ］であった。 The short side is a shown in FIG. 5, and the long side is b shown in FIG. The short side a and the long side b were measured using LS-9120M manufactured by Keyence Corporation. The infusion container 100 was placed on the measuring instrument with the cover member 200 facing down, and the short side a and the long side b of the infusion container 100 at a position of 70 mm in height were measured one by one. The groove depth d was measured using Olympus STM7. The square groove depth d of the substantially rectangular box-shaped infusion container 100 was measured one by one. Table 1 shows the maximum values of the dimension measurement results for each of the short side a, the long side b, and the groove depth d in 10 infusion containers. The groove depth d of the infusion container before the high-pressure steam sterilization treatment was 2.20 [mm] for both the infusion container in which no groove was formed and the infusion container 100 in which the groove 12 was formed.
　溝が形成されていない輸液容器は、滅菌処理後に短辺ａの長さが９．９２［ｍｍ］増加し、長辺ｂの長さが２．９１［ｍｍ］増加した。溝１２が形成されている輸液容器１００は、滅菌処理後に短辺ａの長さが４．９２［ｍｍ］増加し、長辺ｂの長さが２．１９［ｍｍ］増加した。滅菌処理後、溝が形成されていない輸液容器は膨張し、角部が円弧状になった。一方、溝１２が形成されている輸液容器１００は膨張せず、角部１１が円弧状になることもなかった。これにより、溝１２が形成されている輸液容器１００の方が寸法変化は少なく、溝が形成されていない輸液容器よりも容器の変形を抑制できることが示された。 In the infusion container in which no groove was formed, the length of the short side a increased by 9.92 [mm] and the length of the long side b increased by 2.91 [mm] after sterilization. In the infusion container 100 in which the groove 12 was formed, the length of the short side a increased by 4.92 [mm] and the length of the long side b increased by 2.19 [mm] after sterilization. After the sterilization treatment, the infusion container without grooves was expanded, and the corners became arcuate. On the other hand, the infusion container 100 in which the groove 12 was formed did not expand, and the corner 11 did not have an arc shape. Thereby, it was shown that the infusion container 100 in which the groove 12 is formed has less dimensional change, and the deformation of the container can be suppressed than the infusion container in which the groove is not formed.
