バツグの口部に設けられる連通ピースの改良に関
する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a communication piece provided at the opening of a medical bag such as a drug solution bag or a blood bag.
[従来技術及び従来技術の問題点]
血液を無菌状態で採血し、密閉状態で血液成分
を分離分配して保存や輸液等に供するための血液
バツグが知られている。[Prior Art and Problems with the Prior Art] Blood bags are known for collecting blood in a sterile state and separating and distributing blood components in a sealed state for storage, infusion, etc.
第4図はこのバツグの一例を示したもので、採
血チユーブ23及び採血針24を備えた採血バツ
グ20と、血漿採取用のバツグ21とから構成さ
れ、これらバツグ20,21は連通チユーブ22
により、気密的に連結されている。 FIG. 4 shows an example of this bag, which is composed of a blood collection bag 20 equipped with a blood collection tube 23 and a blood collection needle 24, and a plasma collection bag 21.
are airtightly connected.
また、前記採血バツグ20の上縁部には連結筒
25が挿入固定されており、前記連結チユーブ2
2はこの連結筒25の上縁部に嵌入されるととも
に、該連結筒の内部には、連結筒25内の流路を
閉塞し、使用時に開通できるような連通ピース2
6が挿入されている。 Further, a connecting tube 25 is inserted and fixed to the upper edge of the blood collection bag 20, and the connecting tube 25
2 is fitted into the upper edge of the connecting tube 25, and inside the connecting tube is a communicating piece 2 that can close the flow path in the connecting tube 25 and open it during use.
6 has been inserted.
この連通ピース26としては、従来から種々の

5図に示すごとく、頭部27が閉塞した硬質樹脂
製の筒体28に、薄肉部29を形成し、前記頭部
27を連通筒25の外側から押し倒して折るよう
にしたものが使用されている。 Various communication pieces 26 have been proposed in the past, but generally, as shown in FIG. The head 27 is pushed down from the outside of the communication tube 25 and folded.
小片である頭部27に部分的に力を集中させる
ことは、連通筒25が比較的肉厚であり、連通チ
ユーブ22の重量も加わることから、かなりの力
が必要であり、困難であつた。 It is difficult to partially concentrate force on the head 27, which is a small piece, because the communicating tube 25 is relatively thick and the weight of the communicating tube 22 is also added, so a considerable force is required. .
また頭部27の外径は連通筒15の内径よりも
小さいので液体の流通中に開口した筒体の流路を
一時的に遮断する現象も時々みられ、流量の定常
的維持が困難であつた。 In addition, since the outer diameter of the head 27 is smaller than the inner diameter of the communication tube 15, the flow path of the open tube may sometimes be temporarily blocked during liquid flow, making it difficult to maintain a steady flow rate. Ta.
そこで本考案者は以上の課題を解決するため鋭
意検討を重ねた結果次の考案に到達した。 In order to solve the above problems, the present inventor conducted extensive studies and arrived at the following idea.

液体の安定した流路を確保でき一定の流量を維持
できる。[Function] By breaking the notch 3 formed between the protrusion 7 and the body 2, a liquid flow path is opened, and at the same time, the protrusion 4 moves only in the direction of the protrusion tip 8, and is pushed back by the pressure of the liquid. Since there is no leakage, a stable flow path for the liquid can be ensured from beginning to end, and a constant flow rate can be maintained.
[実施例]
第1図は医療用バツグに装着された連結筒12
内に配置される本考案の連通ピース1の概略図を
示す。[Example] Figure 1 shows a connecting tube 12 attached to a medical bag.
1 shows a schematic view of the communicating piece 1 of the present invention placed in the interior.
連通ピース1は胴体部2と突出部7を一体成形
して構成され、これらの間に指圧で破断可能な切
欠部3が形成されている。 The communication piece 1 is constructed by integrally molding a body part 2 and a protrusion part 7, and a cutout part 3 which can be broken by finger pressure is formed between them.
前記胴体部2の外径は、前記連結筒12の内径
により若干大きく形成されるとともに、内部には
液体の流路10が形成されている。 The outer diameter of the body portion 2 is slightly larger than the inner diameter of the connecting tube 12, and a liquid flow path 10 is formed inside.
前記突出部7は、先端に突出先端部8が形成さ
れ、長さ方向の外周面に凸部4と凹部5が交互に
形成され、さらに該長さ方向の外周面に複数のゲ
ート6が不連続(例えば4箇所)に形成されてい
る。 The protruding portion 7 has a protruding tip portion 8 formed at its tip, protrusions 4 and recesses 5 alternately formed on the outer circumferential surface in the longitudinal direction, and a plurality of gates 6 on the outer circumferential surface in the longitudinal direction. They are formed continuously (for example, in four locations).
前記凸部4の外径は、前記連結筒12の内径よ
り若干大きく形成され、凸部4の斜面9前記突出
先端部8方向に傾斜させて形成されている。 The outer diameter of the convex portion 4 is formed to be slightly larger than the inner diameter of the connecting cylinder 12, and the slope 9 of the convex portion 4 is formed to be inclined in the direction of the protruding tip portion 8.
第2図は医療用バツグ11内に収納された液体
を連通ピース1を破断して外部に排出するところ
の一例を示す状態図、第3図は連通ピース1を破
断するところ一例を示す状態図を示す。 FIG. 2 is a state diagram showing an example of when the liquid stored in the medical bag 11 is discharged to the outside by breaking the communicating piece 1, and FIG. 3 is a state diagram showing an example of how the communicating piece 1 is broken. shows.
医療用バツグ11内の液体を連結筒12内まで
導入すると液体は突出先端部8の外円周面に沿つ
て環状に流れを変えて、最初の凸部4を回避し、
4箇所のゲート6に分散して入つた後、切欠部3
まで到達する。 When the liquid in the medical bag 11 is introduced into the connecting cylinder 12, the liquid changes its flow in an annular manner along the outer circumferential surface of the protruding tip 8, avoiding the first protrusion 4,
After entering the gates 6 at four locations, the notch 3
reach up to.
次に、連結筒1の外側から突出部7を押さえた
後(突出部7の外円周には凸部4が形成されてい
るので、外部から固定しやすい)胴体部2を把持
して矢印方向に力Fを加え〓へ〓の字に曲げなが
ら切欠部3が破断するまで力を入れる。この時凸
部4は、斜面9が突出先端部8方向に形成されて
いるので、突出先端部8方向しか移動できない。 Next, after pressing the protrusion 7 from the outside of the connecting cylinder 1 (the protrusion 4 is formed on the outer circumference of the protrusion 7, it is easy to fix it from the outside), grip the body part 2 and Apply a force F in the direction of 〓 to 〓 while bending it in the shape of 〓 until the notch part 3 breaks. At this time, since the slope 9 is formed in the direction of the protruding tip 8, the convex portion 4 can only move in the direction of the protruding tip 8.
この曲げた状態の時、凸部4aはAの位置まで
移動し、次に〓へ〓の字に変形した連通筒12を
基の状態にするために力を加わえると凸部4aの
反対側の凸部4bもAの位置まで移動することに
なる。 In this bent state, the convex part 4a moves to the position A, and then when force is applied to return the communicating tube 12, which has been deformed into the shape of a 〓, to its original state, the opposite side of the convex part 4a is moved. The convex portion 4b will also move to the position A.
以上の操作によつて胴体部2と突出部7の間に
液体の流通機能を維持するために必要な約1mmの
間隔を容易に形成することができる。 By the above operations, it is possible to easily form a gap of approximately 1 mm between the body portion 2 and the protruding portion 7, which is necessary to maintain the fluid flow function.
液体は該間隔を通つて胴体部2内の流体の流路
10、連結チユーブ12、液体移送チユーブ13
を経て排出される。 The liquid passes through the gap to the fluid flow path 10, the connection tube 12, and the liquid transfer tube 13 in the body 2.
It is then discharged.
この時約1mm移動した突出部7の凸部4の外径
は、連通筒12の内径より若干大きく形成されて
いるので、連通筒12に密着して固定されてお
り、医療用バツグ11方向から来る液体の圧力に
押し戻されて基の位置に戻つて液体の流路を妨げ
ることはない。 At this time, the outer diameter of the convex part 4 of the protruding part 7, which has moved by about 1 mm, is formed to be slightly larger than the inner diameter of the communicating tube 12, so it is fixed tightly to the communicating tube 12, and the medical bag 11 can be seen from the direction. It is pushed back by the pressure of the incoming liquid and returns to its original position without blocking the flow path of the liquid.
[考案の効果]
以上説明したように本考案では、突出部7に形
成された凸部4を把持して胴部2に力を加わえる
事により容易に破断でき、同時に突出部7は突出
先端部8方向へのみ移動し、一度開通した流路を
二度と塞ぐ事がないので、終始安定した流量が確
保できる。[Effects of the invention] As explained above, in the present invention, the protrusion 7 can be easily broken by gripping the protrusion 4 formed on the protrusion 7 and applying force to the body 2, and at the same time, the protrusion 7 can be easily broken at the tip of the protrusion. Since it moves only in the direction of section 8 and never closes the flow path once opened, a stable flow rate can be ensured from beginning to end.
