Description

本発明はクランプ及び該クランプを装着した透析用血液回路や高カロリー輸液バックや輸液セット等の医療用具の改良に関する。   The present invention relates to an improvement of a medical device such as a clamp and a blood circuit for dialysis equipped with the clamp, a high calorie infusion bag, an infusion set, and the like.

図８は従来のクランプ３１の概略図で（ａ）は側面図と（ｂ）は斜視図である。クランプ３１は押圧部１２を押して係合突部３４を係合溝３５に係合する時に屈曲部８の力が封止部材３３と押圧部１２を介して前記係合突部３４に伝導するので左右に動きやすい。そして前記係合突部３４と係合溝３５の係合状態は前記係合突部３４の先端天壁面が係止部３６の下部に形成した前記係合溝３５だけで係合しており、係合溝３５又は係合突部３４の両側に該係合突部３４の動きをブロックする物がない為に前記係合突部３４が左右に動いてしまう。その為封止部材３３の下部と底部２の上部に形成した挟持部７ａ、７ｂも同様に左右に動き、チューブ１５を確実に挟持、閉塞ができず、場合によっては係合突部３４と係合溝３５の係合が外れてしまうことも有り得る状況であった。そこで本発明者は以上の課題を解決する為に、鋭意検討を重ねた結果次の発明に到達した。   8A and 8B are schematic views of a conventional clamp 31. FIG. 8A is a side view and FIG. 8B is a perspective view. Since the clamp 31 pushes the pressing portion 12 to engage the engaging protrusion 34 with the engaging groove 35, the force of the bent portion 8 is conducted to the engaging protrusion 34 via the sealing member 33 and the pressing portion 12. Easy to move from side to side. And the engagement state of the engagement protrusion 34 and the engagement groove 35 is engaged only by the engagement groove 35 formed at the lower end of the engagement part 36 at the top ceiling surface of the engagement protrusion 34, Since there is nothing that blocks the movement of the engagement protrusion 34 on both sides of the engagement groove 35 or the engagement protrusion 34, the engagement protrusion 34 moves left and right. Therefore, the holding parts 7a and 7b formed at the lower part of the sealing member 33 and the upper part of the bottom part 2 also move to the left and right in the same manner, so that the tube 15 cannot be securely held or closed. It was a situation where the engagement of the joint groove 35 could be disengaged. Therefore, as a result of intensive studies to solve the above problems, the present inventor has reached the following invention.

特開平１０−１６９６１８号（特許請求の範囲）JP 10-169618 (Claims) 特開平５−３２９２１０号（特許請求の範囲）JP-A-5-329210 (Claims)

本発明が解決しようとする問題点は、従来のクランプ３１は、係合溝３５又は係合突部３４の両側に該係合突部３４の動きをブロックする物がない為に前記係合突部３４が左右に動いてしまう。その為封止部材３３の下部と底部２の上部に形成した挟持部７ａ、７ｂも同様に左右に動き、チューブ１５を確実に挟持、閉塞ができず、場合によっては係合突部３４と係合溝３５の係合が外れてしまう点である。   The problem to be solved by the present invention is that the conventional clamp 31 does not have an object that blocks the movement of the engagement protrusion 34 on either side of the engagement groove 35 or the engagement protrusion 34, so that the engagement protrusion The part 34 moves from side to side. Therefore, the holding parts 7a and 7b formed at the lower part of the sealing member 33 and the upper part of the bottom part 2 also move to the left and right in the same manner, so that the tube 15 cannot be securely held or closed. The point is that the engagement of the mating groove 35 is disengaged.

(D) is a rear view, (e) is a cross-sectional view taken along the line AA ', and (f) is a cross-sectional view taken along the line BB'. FIG. 2 is a perspective view of the clamp 1. The sealing member 3 is formed integrally with the bottom portion 2 via a bent portion 8, and a locking portion 6 is formed on the bottom portion 2 via a connecting portion 14. A sandwiching portion 7 a and a sandwiching portion 7 b are formed at the lower portion of the sealing member 3 and the upper portion of the bottom portion 2, and insertion holes 10 a and 10 b are formed at substantially middle portions of the bent portion 8 and the connecting portion 14. The tube 15 is disposed between the holding portions 7a and 7b through the insertion holes 10a and 10b. A wave-like pressing portion 12 is formed at the front upper portion of the sealing member 3, and a tapered engagement protrusion 4 is formed at the tip of the wave-shaped pressing portion 12 so as to be narrower than the width of the sealing member 3. A rectangular engaging groove 5 narrower than the width of the locking portion 6 is formed in the lower portion of the engaging portion 6. Further, walls 9 are formed on both sides of the connecting portion 14.

図３は参考例のチューブ１５を通したクランプ１を閉じた時の展開図で、（ａ）は該クランプ１の側面図で、（ｂ）は平面図、（ｃ）は正面図、（ｄ）は背面図、（ｅ）はＡ−Ａ′の断面図、（ｆ）はＢ−Ｂ′の断面図である。図４は図３の（ａ）クランプ１の斜視図である。前記クランプ１に装着したチューブ１５を閉塞するには、封止部材３の前方上部に形成した押圧部１２を指で押し、封止部材３先端の係合突部４が係止部６の内側の傾斜状の誘導面１３に沿って係止部６の下部の四角形状の係合溝５と係合する。すなわち前記先細りの係合突部４の両側外壁面が係合溝５の両側に隣接する前記係止部６の両側内壁面に沿って係入し、且つ前記係合突部４の先端天壁面が、前記係合溝５の上部に隣接する係止部６の底壁面と係合する。前記係合溝５の両側に隣接する前記係止部６の両側内壁面が前記係合突部４の左右の動きをブロックし屈曲部８の力が前記係合突部４に伝導しないので該係合突部４は左右に動くことなく、前記チューブ１５も挟持部７ａ、７ｂから外れることなく確実に閉塞することができる。遮断したチューブ１５を解放するには、係止部６に形成した誘導面１３を親指で押し開くことで、屈曲部８の反動により係合した係合突部４と係合溝５が外れると同時にチューブ１５を押圧挟持していた挟持部７ａ、７ｂも解放されチューブ１５の閉塞も解除される。   3 is a developed view when the clamp 1 is passed through the tube 15 of the reference example, (a) is a side view of the clamp 1, (b) is a plan view, (c) is a front view, (d ) Is a rear view, (e) is a cross-sectional view taken along line A-A ', and (f) is a cross-sectional view taken along line BB'. FIG. 4 is a perspective view of the clamp 1 in FIG. In order to close the tube 15 attached to the clamp 1, the pressing portion 12 formed on the front upper portion of the sealing member 3 is pushed with a finger, and the engaging protrusion 4 at the tip of the sealing member 3 is located inside the locking portion 6. It engages with the rectangular engaging groove 5 below the locking portion 6 along the inclined guide surface 13. That is, the outer wall surfaces on both sides of the tapered engaging protrusion 4 are engaged along the inner wall surfaces on both sides of the engaging portion 6 adjacent to both sides of the engaging groove 5, and the top ceiling wall surface of the engaging protrusion 4. Engages with the bottom wall surface of the engaging portion 6 adjacent to the upper portion of the engaging groove 5. The inner wall surfaces on both sides of the engaging portion 6 adjacent to both sides of the engaging groove 5 block the left and right movements of the engaging protrusion 4 and the force of the bent portion 8 is not conducted to the engaging protrusion 4. The engagement protrusion 4 does not move left and right, and the tube 15 can be reliably closed without being disengaged from the holding portions 7a and 7b. In order to release the blocked tube 15, the guide surface 13 formed on the locking portion 6 is pushed open with the thumb so that the engaging protrusion 4 and the engaging groove 5 engaged by the reaction of the bent portion 8 are released. At the same time, the holding portions 7a and 7b that press and hold the tube 15 are also released, and the blockage of the tube 15 is released.

前記のように挿入孔１０ａ、１０ｂを通り、挟持部７ａ、７ｂで押圧挟持したチューブ１５は前記係合突部４と係合溝５の係合により、挟持部７ａ、７ｂの左右の動きがなくなると同時にチューブ１５の外れがなくなるが、更に安全性を増す為に前記チューブ１５が押圧挟持した挟持部７ａ、７ｂの間から外れない様に連結部１４の両側に壁９を形成することができる。前記壁９を形成することによりクランプ１の開閉する際のチューブ１５の撓みを防ぐことができ、前記チューブ１５が挟持部７ａ、７ｂから外れることは完全に解消される。   As described above, the tube 15 that has passed through the insertion holes 10a and 10b and is pressed and clamped by the clamping portions 7a and 7b has the left and right movements of the clamping portions 7a and 7b due to the engagement of the engagement protrusion 4 and the engagement groove 5. At the same time, the tube 15 does not come off, but in order to further increase safety, the walls 9 may be formed on both sides of the connecting portion 14 so that the tube 15 does not come off between the holding portions 7a and 7b pressed and clamped. it can. By forming the wall 9, it is possible to prevent the tube 15 from being bent when the clamp 1 is opened and closed, and the tube 15 is completely prevented from coming off from the holding portions 7 a and 7 b.

図５は参考例のクランプ１のその他の実施例を示すクランプ１１で、（ａ）はチューブ１５を装着した時の側面図で（ｂ）はその斜視図である。クランプ１１は前記連結部１４の両側に形成した壁９を省略したクランプである。該クランプ１１は前記クランプ１と同じように封止部材３の幅より狭く形成し先細りの係合突部４の幅の両側外壁面と、前記係止部６の幅より狭い四角形状の係合溝５に隣接する前記係止部６の両側内壁面が係合することにより前記係合突部４は左右に動くことはない。従って挿入孔１０ａ、１０ｂに通り挟持部７ａ、７ｂにより押圧挟持されたチューブ１５も左右に動くことはないので壁９を省略することができる。   FIG. 5 is a clamp 11 showing another embodiment of the clamp 1 of the reference example, (a) is a side view when the tube 15 is mounted, and (b) is a perspective view thereof. The clamp 11 is a clamp in which the walls 9 formed on both sides of the connecting portion 14 are omitted. The clamp 11 is formed narrower than the width of the sealing member 3 in the same manner as the clamp 1, and the both side outer wall surfaces of the width of the tapered engaging protrusion 4 and the rectangular engagement narrower than the width of the locking portion 6. When the inner wall surfaces on both sides of the engaging portion 6 adjacent to the groove 5 are engaged, the engaging protrusion 4 does not move left and right. Therefore, the tube 9 that is pressed and clamped by the clamping portions 7a and 7b through the insertion holes 10a and 10b does not move left and right, and thus the wall 9 can be omitted.

図６は本発明の実施例を示すクランプ２１Ａで、装着したチューブ１５を閉塞した時の斜視図である。前記クランプ２１Ａは、前記封止部材３の先端に該封止部材３と同じ幅の係合突部４ａを設け、係止部６ａ及び連結部１４の両外壁側に亘って壁９ａを形成したものである。その他の形状は前記クランプ１、１１と実質的に同じなので各構成部品の説明は省略する。係合突部４ａの両側壁面は前記壁９ａの両側内壁面に沿って係入し、前記係合突部４ａの先端天壁面が前記係合溝５ａの上部に隣接する係止部６ａの底部壁面と係合する。前記壁９ａの両側内壁面が、前記係合突部４ａの左右の動きをブロックするので、係合突部４ａは左右に動くことはなくなる。
更に詳述すれば、押圧部１２を押した時、係合突部４ａの両側外壁面は前記壁９ａの両側内壁面に沿って係入されると共に前記係合突部４ａの先端は誘導面１３に沿って係入するので、前記係合突部４ａは左右に動くことなく係合溝５ａと係合することができる。
更に前記係合突部４ａの先端天壁面が前記係合溝５ａの上部に隣接する係止部６ａの底部壁面と係合することで、屈曲部８の力が前記係合突部４ａに伝導しないので、前記チューブ１５も挟持部７ａ、７ｂから外れることなく確実にチューブ１５を閉塞することができる。
更に前記誘導面１３の壁９ａの先端は、係合突部４ａを誘導面１３に導入しやすくするために多少外側に広げた方が良い。 FIG. 6 is a perspective view when the attached tube 15 is closed with a clamp 21A showing an embodiment of the present invention. The clamp 21A is provided with an engagement protrusion 4a having the same width as the sealing member 3 at the tip of the sealing member 3, and a wall 9a is formed across both outer wall sides of the locking portion 6a and the connecting portion 14. Is. Since other shapes are substantially the same as those of the clamps 1 and 11, description of each component will be omitted. Both side wall surfaces of the engagement protrusion 4a are engaged along both inner wall surfaces of the wall 9a, and the top ceiling wall surface of the engagement protrusion 4a is adjacent to the top of the engagement groove 5a. Engage with the wall. Since the inner wall surfaces on both sides of the wall 9a block the left and right movements of the engaging protrusion 4a, the engaging protrusion 4a does not move left and right.
More specifically, when the pressing portion 12 is pressed, the outer wall surfaces on both sides of the engaging protrusion 4a are engaged along the inner wall surfaces on both sides of the wall 9a, and the tip of the engaging protrusion 4a is the guide surface. 13, the engaging protrusion 4a can engage with the engaging groove 5a without moving left and right.
Further, the top ceiling wall surface of the engaging protrusion 4a engages with the bottom wall surface of the locking portion 6a adjacent to the upper portion of the engaging groove 5a, whereby the force of the bent portion 8 is transmitted to the engaging protrusion 4a. Therefore, the tube 15 can be reliably closed without detaching from the sandwiching portions 7a and 7b.
Further, the tip of the wall 9a of the guide surface 13 should be widened slightly outward so that the engaging protrusion 4a can be easily introduced into the guide surface 13.

図７は本発明のその他の実施例を示すクランプ２１Ｂで、装着したチューブ１５を閉塞した時の斜視図である。前記クランプ２１Ｂは、前記クランプ２１Ａの係止部６ａ及び連結部１４の両外側に亘って形成した壁９ａの代わりに、封止部材３の先端に形成した係合突部４ａの両側に板状の壁９ｂを形成したものである。前記板状の壁９ｂは図示した略半円形状や四角形状でも良い。その他の形状は前記クランプ２１Ａと実質的に同じなので各構成部品の説明は省略する。前記壁９ｂの両側内壁面は、前記係止部６ａ及び連結部１４の両側外壁面に沿って係入し、前記係合突部４ａの先端天壁面が前記係合溝５ａの上部に隣接する係止部６ａの底部壁面に係合する。
前記壁９ｂの両側内壁面が前記係合突部４ａの左右の動きをブロックするので、前記係合突部４ａは左右に動くことがなくなる。さらに前記係合突部４ａの先端天壁面が前記係合溝５ａの上部に隣接する前記係止部６ａの底壁面と係合することで、前記クランプ２１Ａと同様に屈曲部８の力が前記係合突部４ａに伝導しないので前記チューブ１５も挟持部７ａ、７ｂから外れることなく確実にチューブ１５を閉塞することができる。 FIG. 7 is a perspective view when the attached tube 15 is closed with a clamp 21B according to another embodiment of the present invention. The clamp 21B has a plate-like shape on both sides of the engaging protrusion 4a formed at the tip of the sealing member 3 instead of the wall 9a formed over both outer sides of the engaging portion 6a and the connecting portion 14 of the clamp 21A. The wall 9b is formed. The plate-like wall 9b may have a substantially semicircular shape or quadrangular shape as illustrated. Since other shapes are substantially the same as those of the clamp 21A, description of each component will be omitted. The inner wall surfaces on both sides of the wall 9b are engaged along the outer wall surfaces on both sides of the engaging portion 6a and the connecting portion 14, and the top ceiling wall surface of the engaging protrusion 4a is adjacent to the upper portion of the engaging groove 5a. Engage with the bottom wall surface of the locking portion 6a.
