Description

本発明は、チューブ部材を接続するためのアダプタが経腸栄養剤などが充填されたスパウト付きパウチに取り付けられている、キャップ付きアダプタを備えるスパウト付きパウチに関する。   The present invention relates to a pouch with a spout having an adapter with a cap, in which an adapter for connecting a tube member is attached to a pouch with a spout filled with an enteral nutrient or the like.

従来、ビタミン類やアミノ酸などを含む経腸栄養剤、流動食、水分補強ゼリーなどを患者に投与するため、経腸栄養剤などが充填されたスパウト付きパウチが用いられている。
このスパウト付きパウチ内の充填物を患者に投与する際には、スパウトにカテーテルのようなチューブ部材を取り付けるが、一般には、スパウトとチューブ部材は、アダプタを介して取り付けられる。
特許文献１には、チューブ部材を圧入する先細テーパ状の接続部とスパウトに取り付ける取付部とを有し、前記接続部に形状の異なる滑り止め部が形成されている、アダプタが開示されている。 Conventionally, pouches with a spout filled with enteral nutrients and the like have been used to administer enteral nutrients including vitamins and amino acids, liquid foods, water-reinforcing jelly, and the like to patients.
When the filling in the pouch with a spout is administered to a patient, a tube member such as a catheter is attached to the spout. Generally, the spout and the tube member are attached via an adapter.
Patent Literature 1 discloses an adapter having a tapered connection portion for press-fitting a tube member and an attachment portion attached to a spout, and an anti-slip portion having a different shape formed in the connection portion. .

かかるアダプタは、次のようにして使用される。
スパウト付きパウチのスパウトからキャップを外し、スパウトの注出口を開口させる。次に、スパウトのネジ部にアダプタの取付部を螺合する。このアダプタの接続部にチューブ部材を接続する。そして、このチューブ部材を通じて、スパウト付きパウチ内の充填物が患者などに投与される。 Such an adapter is used as follows.
Remove the cap from the spout of the pouch with spout and open the spout spout. Next, the adapter mounting portion is screwed into the spout thread portion. A tube member is connected to the connecting portion of this adapter. And the filler in the pouch with a spout is administered to a patient etc. through this tube member.

しかしながら、スパウトのキャップを外し、さらに、アダプタを取り付けている間に、スパウトの注出口やネジ部に粉塵や雑菌などが付着するおそれがある。また、スパウトにアダプタを取り付ける際には、アダプタの接続部を手で持ってスパウトに螺合するので、衛生面から好ましいものとは言えない。   However, while removing the cap of the spout and attaching the adapter, dust or germs may adhere to the spout spout and the screw portion. Further, when the adapter is attached to the spout, it is not preferable from the viewpoint of hygiene because the adapter connecting portion is held by hand and screwed into the spout.

さらに、アダプタをスパウトに完全に螺合させずに、チューブ部材を接続して使用する場合がある。一方、当初、アダプタをスパウトに完全に螺合させていても、アダプタの接続部には患者に繋がったチューブ部材が接続されているので、使用している間に、アダプタの取付部がスパウトから緩むおそれがある。また、使用途中で、患者などが誤ってアダプタを回してスパウトから外すおそれもある。アダプタがスパウトに完全に螺合していないと、スパウトとアダプタの隙間から充填物が漏れてしまう。   Further, the tube member may be connected and used without completely screwing the adapter into the spout. On the other hand, since the tube member connected to the patient is connected to the connection portion of the adapter even if the adapter is completely screwed into the spout at the beginning, the adapter attachment portion is not removed from the spout during use. There is a risk of loosening. In addition, during use, the patient may accidentally turn the adapter and remove it from the spout. If the adapter is not completely screwed into the spout, the filler will leak from the gap between the spout and the adapter.

加えて、従来のアダプタにあっては、チューブ部材を接続して充填物を投与し始めると、その途中で投与を一旦止め、チューブ部材をアダプタから外すことができない。チューブ部材をアダプタから外すと、アダプタの注出口を密封状に封緘しなければならないが、従来のアダプタは、その注出口を適切に且つ簡易に封緘するための手段を有さない。   In addition, in the conventional adapter, when the tube member is connected and the filling is started, the administration is temporarily stopped in the middle of the administration, and the tube member cannot be removed from the adapter. When the tube member is removed from the adapter, the spout of the adapter must be sealed in a sealed manner, but conventional adapters do not have a means for properly and easily sealing the spout.

特開２００９−１３６４２７号公報JP 2009-136427 A

Thus, the adapter B with a cap can be obtained.

スクリューキャップ４がアダプタ３に完全に螺合した状態においては、キャップ本体８のシール部８５によってアダプタ３の接続部５の開口が塞がれていると共に、キャップ本体８によってアダプタ３の接続部５が封緘され、さらに、環状部９の上端面が取付部６の小突部６６と取付部係合部６３の間に位置していると共に、環状部９の環状部被係合部９３がアダプタ３の取付部係合部６３に係合している。
このように環状部被係合部９３と取付部係合部６３が係合することにより、環状部９を緩方向に回そうとしても環状部被係合面９３ｂが取付部係合面６３ｂに当たるので、環状部９を緩方向に回転させることができない。 In a state where the screw cap 4 is completely screwed into the adapter 3, the opening of the connection portion 5 of the adapter 3 is blocked by the seal portion 85 of the cap body 8, and the connection portion 5 of the adapter 3 is blocked by the cap body 8. In addition, the upper end surface of the annular portion 9 is positioned between the small protrusion 66 of the attachment portion 6 and the attachment portion engaging portion 63, and the annular portion engaged portion 93 of the annular portion 9 is an adapter. 3 is engaged with the attachment portion engaging portion 63.
By engaging the annular portion engaged portion 93 and the attachment portion engaging portion 63 in this manner, the annular portion engaged surface 93b hits the attachment portion engaging surface 63b even if the annular portion 9 is rotated in the slow direction. Therefore, the annular portion 9 cannot be rotated in the gentle direction.

このキャップ付きアダプタＢは、図１及び図３に示すように、スクリューキャップ４の環状部９の下端面４ａがアダプタ３の取付部６の下端面６ａよりも上方に位置している。従って、キャップ付きアダプタＢを正面から見て、アダプタ３の取付部６の下方部を視認できる。
アダプタ３の全体がスクリューキャップ４によって覆われていると、スクリューキャップ４がアダプタ３に対して完全に螺合しているかどうか目視で判断し難い。この点、本実施形態のキャップ付きアダプタＢによれば、スクリューキャップ４がアダプタ３に対して完全に螺合しているかどうかをその外部から確認できる。 As shown in FIGS. 1 and 3, the adapter B with a cap is such that the lower end surface 4 a of the annular portion 9 of the screw cap 4 is positioned above the lower end surface 6 a of the attachment portion 6 of the adapter 3. Therefore, the lower part of the attachment part 6 of the adapter 3 can be visually recognized when the adapter B with a cap is viewed from the front.
If the entire adapter 3 is covered with the screw cap 4, it is difficult to visually determine whether the screw cap 4 is completely screwed into the adapter 3. In this regard, according to the adapter B with a cap of the present embodiment, it can be confirmed from the outside whether or not the screw cap 4 is completely screwed to the adapter 3.

＜キャップ付きアダプタを備えるスパウト付きパウチについて＞
キャップ付きアダプタＢを備えるスパウト付きパウチＡは、次のようにして得ることができる。
スパウト付きパウチＡのスパウト１の注出口から袋２の内部に、充填物を充填する。本発明のスパウト付きパウチＡは、スパウト１から袋２内に充填物を充填できるので、袋２の内部に生じるデッドスペース（充填物が充填されていない空間）を小さくできる。一般的にスパウトが取り付けられていない袋の開口部から充填物を充填すると、比較的大きなデッドスペースが生じるが、本発明のスパウト付きパウチＡにあっては、デッドスペースが小さくなるため、正味の充填量に適合した容量の袋を用いることができる。このため、本発明では、袋のコストや保管運搬費の低減を図ることができる。さらに、本発明のスパウト付きパウチＡに対する充填物の充填は、既存の充填装置を用いて行うことができるので、新たな設備投資を行う必要もない。 <About pouch with spout equipped with adapter with cap>
The pouch A with a spout provided with the adapter B with a cap can be obtained as follows.
The filling material is filled into the inside of the bag 2 from the spout 1 of the spout 1 of the pouch A with spout. Since the pouch A with a spout of the present invention can be filled with the filling from the spout 1 into the bag 2, the dead space (space where the filling is not filled) generated in the bag 2 can be reduced. In general, filling a filling from an opening of a bag to which a spout is not attached causes a relatively large dead space. However, in the pouch A with a spout of the present invention, the dead space is reduced, so that the net A bag with a capacity suitable for the filling amount can be used. For this reason, in this invention, reduction of the cost of a bag and the storage conveyance cost can be aimed at. Furthermore, since the filling of the pouch A with a spout of the present invention can be performed using an existing filling device, it is not necessary to make a new capital investment.

充填物を充填した後、スパウト１からキャップ付きアダプタＢを挿入し、これをアダプタ３の締方向に回していく。キャップ付きアダプタＢの回転に従い、アダプタ３のネジ部６８がスパウト１のネジ部１８に螺合していく。キャップ本体８の締方向とアダプタ３の締方向は同じ方向なので、アダプタ３を取り付けている途中で、キャップ本体８がアダプタ３から外れることはない。
そして、アダプタ３の取付部被係合部６１がスパウト係合部１１に接する所までアダプタ３が螺合されると、取付部被傾斜面６１ａがスパウト傾斜面１１ａを乗り越えていくので、アダプタ３の回転が阻害されず、キャップ付きアダプタＢをスパウト１に完全に螺合できる。
このようにしてキャップ付きアダプタＢを備えるスパウト付きパウチＡを得ることができる。 After filling the filling material, the adapter B with the cap is inserted from the spout 1, and this is rotated in the tightening direction of the adapter 3. As the adapter B with the cap rotates, the screw portion 68 of the adapter 3 is screwed into the screw portion 18 of the spout 1. Since the tightening direction of the cap body 8 and the tightening direction of the adapter 3 are the same direction, the cap body 8 is not detached from the adapter 3 while the adapter 3 is being attached.
When the adapter 3 is screwed to the place where the attachment portion engaged portion 61 of the adapter 3 comes into contact with the spout engagement portion 11, the attachment portion inclined surface 61a gets over the spout inclined surface 11a. Is not hindered, and the adapter B with the cap can be completely screwed onto the spout 1.
In this way, a pouch A with a spout having an adapter B with a cap can be obtained.

キャップ付きアダプタＢがスパウト１に完全に螺合した状態においては、アダプタ３のシール部６５によってスパウト１の注出口が塞がれていると共に、アダプタ３の取付部被係合部６１がスパウト１のスパウト係合部１１に係合している。
このように取付部被係合部６１とスパウト係合部１１が係合することにより、アダプタ３を緩方向に回そうとしても取付部被係合面６１ｂがスパウト係合面１１ｂに当たるので、アダプタ３を緩方向に回転させることができない。 In a state where the adapter B with the cap is completely screwed into the spout 1, the spout 1 of the spout 1 is blocked by the seal portion 65 of the adapter 3, and the attachment portion engaged portion 61 of the adapter 3 is connected to the spout 1. The spout engaging portion 11 is engaged.
Since the attachment portion engaged portion 61 and the spout engagement portion 11 are engaged in this manner, the attachment portion engaged surface 61b hits the spout engagement surface 11b even if the adapter 3 is rotated in the loose direction. 3 cannot be rotated slowly.

得られたキャップ付きアダプタＢを備えるスパウト付きパウチＡを使用する場合、キャップ本体８を緩方向に回してアダプタ３を露出させる。
アダプタ３の取付部６が緩方向の回転を規制する回止め手段によってスパウト１に取り付けられているので、キャップ本体８を緩方向に回した際に、アダプタ３がスパウト１から外れることはない。
また、環状部９はアダプタ３の緩方向に回転しないようにアダプタ３に係合しているので、キャップ本体８を回すと、架橋部８９が破断してキャップ本体８のみをアダプタ３から取り外すことができる（図１１参照）。 When the pouch A with a spout provided with the obtained adapter B with a cap is used, the adapter 3 is exposed by turning the cap body 8 in a loose direction.
Since the attachment portion 6 of the adapter 3 is attached to the spout 1 by the rotation stopping means that restricts the rotation in the slow direction, the adapter 3 does not come off the spout 1 when the cap body 8 is turned in the slow direction.
Since the annular portion 9 is engaged with the adapter 3 so as not to rotate in the loose direction of the adapter 3, when the cap body 8 is turned, the bridging portion 89 is broken and only the cap body 8 is removed from the adapter 3. (See FIG. 11).

キャップ本体８を外すことによって露出したアダプタ３の接続部５に、チューブ部材を圧入することにより、チューブ部材を通じて、スパウト付きパウチＡの充填物を患者などに投与できる。チューブ部材は、特に限定されず、単なる柔軟な管（ゴム管や柔軟なプラスチック管など）でもよいし、或いは、特開２００９−１３６４２７号に開示されたような接続管付きの胃ろうカテーテルなどでもよい。   By inserting the tube member into the connection portion 5 of the adapter 3 exposed by removing the cap body 8, the filling of the pouch A with the spout can be administered to the patient or the like through the tube member. The tube member is not particularly limited, and may be a simple flexible tube (such as a rubber tube or a flexible plastic tube), or a gastric fistula catheter with a connecting tube as disclosed in JP-A-2009-136427. Good.

本発明のキャップ付きアダプタＢを備えるスパウト付きパウチＡは、アダプタ３をスパウト付きパウチＡに取り付けるときに、アダプタ３に直接触れないので、チューブ部材を取り付けるアダプタ３に粉塵や雑菌などが付着し難い。
また、キャップ本体８のみを簡単に外すことができる上、使用者がアダプタ３をスパウト付きパウチＡに取り付ける作業も不要であるので、取り扱いが簡便である。
さらに、回止め手段によってアダプタ３がスパウト１から緩まないので、チューブ部材を通じて充填物を注出している途中に、アダプタ３とスパウト１の間から充填物が液漏れしない。さらに、患者や補助者などが誤ってアダプタ３を回そうとしても、アダプタ３がスパウト１から緩むこともない。 Since the pouch A with a spout having the adapter B with a cap according to the present invention does not directly touch the adapter 3 when the adapter 3 is attached to the pouch A with a spout, dust, bacteria, etc. are not easily attached to the adapter 3 to which the tube member is attached. .
Moreover, since only the cap main body 8 can be easily removed and the user does not need to attach the adapter 3 to the pouch A with a spout, the handling is simple.
Furthermore, since the adapter 3 is not loosened from the spout 1 by the turning stop means, the filling material does not leak from between the adapter 3 and the spout 1 while the filling material is being poured out through the tube member. Further, even if a patient or an assistant tries to turn the adapter 3 by mistake, the adapter 3 does not loosen from the spout 1.

さらに、取り外したキャップ本体８は、アダプタ３のネジ部７に再度螺合させることもできる。このため、例えば、充填物の注出を一旦止めてチューブ部材をアダプタ３から引き抜き、アダプタ３にキャップ本体８を再度螺合して、アダプタ３を再封することもできる。再び充填物を注出したい場合には、キャップ本体８をアダプタ３から外し、アダプタ３にチューブ部材を取り付ければよい。   Further, the removed cap body 8 can be screwed again into the screw portion 7 of the adapter 3. For this reason, for example, the filling material can be temporarily stopped, the tube member is pulled out from the adapter 3, the cap body 8 is screwed into the adapter 3 again, and the adapter 3 can be resealed. When it is desired to pour out the filler again, the cap body 8 may be removed from the adapter 3 and a tube member may be attached to the adapter 3.

なお、キャップ本体８をアダプタ３から取り外した後、キャップ本体８で再封しても、架橋部８９が破断しているので、キャップ本体８と環状部９は当初のように連結された状態にはならない。従って、環状部９の状態を見れば、キャップ本体８が既に開封されたかどうかを簡単に確認できる。
また、スクリューキャップ４がアダプタ３に完全に螺合した状態において、環状部９は、その上端面が取付部６の小突部６６と取付部係合部６３の間に位置されており、この小突部６６の外径は、キャップ本体８の下方内周面の内径よりも僅かに小さく且つ環状部９の上方内周面の内径よりも僅かに大きい。このため、環状部９をアダプタ３の上方に抜き取ることが困難であるので、悪意者がキャップ本体８を開封後、開封の有無の確認対象となる環状部９を抜き取るという行為を防止できる。 Even if the cap body 8 is removed from the adapter 3 and then resealed with the cap body 8, the bridging portion 89 is broken, so that the cap body 8 and the annular portion 9 are connected as in the initial state. Must not. Therefore, by looking at the state of the annular portion 9, it can be easily confirmed whether or not the cap body 8 has already been opened.
Further, in a state where the screw cap 4 is completely screwed into the adapter 3, the upper end surface of the annular portion 9 is located between the small protrusion 66 of the attachment portion 6 and the attachment portion engaging portion 63. The outer diameter of the small protrusion 66 is slightly smaller than the inner diameter of the lower inner peripheral surface of the cap body 8 and slightly larger than the inner diameter of the upper inner peripheral surface of the annular portion 9. For this reason, since it is difficult to extract the annular part 9 above the adapter 3, it is possible to prevent the Service-to-Self from extracting the annular part 9 to be checked for the presence / absence of opening after the cap body 8 is opened.

なお、本発明のキャップ付きアダプタ及びこれを備えるスパウト付きパウチは、上記実施形態に限られず、本発明の意図する範囲で適宜変更できる。
例えば、上記実施形態のアダプタ３の接続部５においては、小径接続部５１及び大径接続部５２を有するが、小径接続部５１だけであってもよい。
また、上記実施形態のキャップ本体８は、アダプタ３の接続部５及び取付部６を封緘するように形成されているが、キャップ本体８は、少なくとも接続部５を封緘可能に形成されていればよく、例えば、取付部６の外周面のネジ部７の一部分が露出するようにスクリューキャップ４が取り付けられていてもよい。 In addition, the adapter with a cap of this invention and the pouch with a spout provided with this are not restricted to the said embodiment, In the range which this invention intends, it can change suitably.
For example, the connection portion 5 of the adapter 3 of the above embodiment includes the small diameter connection portion 51 and the large diameter connection portion 52, but only the small diameter connection portion 51 may be provided.
Moreover, although the cap main body 8 of the said embodiment is formed so that the connection part 5 and the attachment part 6 of the adapter 3 may be sealed, as long as the cap main body 8 is formed so that at least the connection part 5 can be sealed. For example, the screw cap 4 may be attached so that a part of the screw portion 7 on the outer peripheral surface of the attachment portion 6 is exposed.

また、取付部６のスパウト１に対する回転を規制する回止め手段、及び、環状部９のアダプタ３に対する回転を規制するための係合手段は、上記実施形態の構成に限られず、本発明の意図する範囲で変更できる。   Further, the rotation stopping means for restricting the rotation of the attachment portion 6 with respect to the spout 1 and the engaging means for restricting the rotation of the annular portion 9 with respect to the adapter 3 are not limited to the configuration of the above-described embodiment, but the intent of the present invention. The range can be changed.

本発明のキャップ付きアダプタを備えるスパウト付きパウチは、チューブ部材を取り付けて、パウチ内の充填物を患者などに投与するために使用できる。   A spout pouch comprising the adapter with a cap of the present invention can be used to attach a tube member and administer the filling in the pouch to a patient or the like.
