Description

本発明は、使い捨てバッグ（シングルユースバッグ）などの可撓性（弾性も含む）のある撹拌容器内の内容物を撹拌する撹拌装置に関する。   The present invention relates to a stirring device that stirs contents in a flexible (including elastic) stirring container such as a disposable bag (single-use bag).

医薬分野等で使用される液体などの撹拌においては、撹拌後の撹拌容器内の洗浄が困難であることから、撹拌容器は、再利用せず、一度きりの使用（シングルユース）となる。   In stirring a liquid or the like used in the medical field or the like, it is difficult to clean the stirring container after stirring. Therefore, the stirring container is not reused but is used only once (single use).

このようなシングルユースの撹拌容器は、経済性の観点から、可撓性のある合成樹脂製（プラスチック製、エラストマー製）の使い捨て（シングルユース）バッグなどの可撓性容器が用いられる。   As such a single-use stirring container, a flexible container such as a disposable (single-use) bag made of flexible synthetic resin (made of plastic or elastomer) is used from the viewpoint of economy.

このシングルユースバッグ内の内容物の撹拌は、従来においては、バッグ内に挿入した回転式撹拌翼により、内容物を撹拌していたが、該回転式撹拌翼の回転軸とバッグとの間で摺動部分が存在し、この摺動部分を通じて、外部から容器内部に異物が挿入（コンタミ）したり、または、内容物が容器外部に漏れてしまうという危険性があった。   Conventionally, the contents in the single use bag are stirred by a rotary stirring blade inserted into the bag. However, between the rotating shaft of the rotary stirring blade and the bag, the contents are stirred. There is a sliding portion, and there is a risk that foreign matter may be inserted (contaminated) from the outside into the container through the sliding portion, or the contents may leak to the outside of the container.

この摺動部分の問題点を解決するために、例えば、超電導を利用して、バッグ内に挿入した撹拌翼をバッグ底部から浮上させて、該撹拌翼の回転手段と非接触で該撹拌翼を回転させることにより、容器内の内容物を撹拌させる撹拌装置がある。この撹拌装置によれば、バッグを完全密閉状態で内容物を撹拌することができるので、異物の混入（コンタミ）や、内容物が容器外部に漏れる危険性はない（特許文献１）。   In order to solve the problem of the sliding portion, for example, using superconductivity, the stirring blade inserted into the bag is levitated from the bottom of the bag, and the stirring blade is not contacted with the rotating means of the stirring blade. There is an agitation device that agitates the contents in the container by rotating. According to this stirring device, the contents can be stirred with the bag completely sealed, so there is no risk of contamination (contamination) or leakage of the contents outside the container (Patent Document 1).

An agitating blade, a means for reciprocating the drive shaft, and a member for preventing damage that is fixed through the drive shaft so that the flexible container can be pressed when the drive shaft moves. The drive shaft fixed to the stirring vessel can be reciprocated using the flexibility and elasticity of the stirring vessel, so that no special sealing portion is provided in the vessel. Can be stirred in a sealed state.

本発明によれば、特別なシール部を設けることなく、可撓性撹拌容器と回転しない駆動軸と撹拌翼の一体構造が可能となり、容器を完全密閉状態とでき、異物の混入（コンタミ）や、内容物が容器外部に漏れる危険性が無くなる。また、撹拌翼を大きくすることができるなど、適切な流動・撹拌作用を得るための撹拌翼のデザインを自由に設計でき、無菌性と良好な撹拌の両方を実現することができる。   According to the present invention, an integrated structure of a flexible stirring container, a non-rotating drive shaft and a stirring blade can be provided without providing a special seal portion, the container can be completely sealed, and foreign matter contamination (contamination) or The risk of the contents leaking outside the container is eliminated. In addition, the size of the stirring blade can be increased, and the design of the stirring blade for obtaining an appropriate flow and stirring action can be freely designed, so that both sterility and good stirring can be realized.

Moreover, it is preferable to make the inside of the flexible stirring vessel 2 have a positive pressure (at least atmospheric pressure).

次に、本発明の撹拌装置の作動及びその効果について説明する。   Next, the operation of the stirring device of the present invention and the effects thereof will be described.

駆動軸３が固定された、被撹拌物を収納した可撓性撹拌容器２を収納容器などの固定手段１４に収納する。なお、該固定手段１４が収納容器である場合には、該収納容器内に前記可撓性撹拌容器２を挿入することにより、前記可撓性撹拌容器２は、その被撹拌物の重さにより変形して、該収納容器内に嵌合して、固定されるようになる。   The flexible agitation container 2 storing the object to be stirred, to which the drive shaft 3 is fixed, is stored in a fixing means 14 such as a storage container. In the case where the fixing means 14 is a storage container, the flexible stirring container 2 is inserted into the storage container so that the flexible stirring container 2 has the weight of the object to be stirred. It is deformed and fitted into the storage container and fixed.

なお、上記可撓性撹拌容器２内の上部は気体で満たされ、この気体は陽圧（大気圧以上）となるようにするのが好ましい。   In addition, it is preferable that the upper part in the said flexible stirring container 2 is filled with gas, and this gas is made to become a positive pressure (atmospheric pressure or more).

そして、前記駆動軸３の上端を、前記往復駆動装置７のモータ軸７ａに締結手段８を介して連結する。   Then, the upper end of the drive shaft 3 is connected to the motor shaft 7 a of the reciprocating drive device 7 via a fastening means 8.

そして、前記往復駆動装置７を駆動することにより、上記撹拌翼６が前記被撹拌物内で上下動など往復動し、該被撹拌物が撹拌される。また、上下撹拌方式を採用することにより、撹拌性能を上げることができる。   Then, by driving the reciprocating drive device 7, the stirring blade 6 reciprocates in the object to be stirred, such as moving up and down, and the object to be stirred is stirred. Moreover, the stirring performance can be improved by adopting the vertical stirring method.

この際、図２及び図３に示すように、前記可撓性撹拌容器２の天井壁２ａが上下に撓むので、上記駆動軸３が上下動等の往復移動ができるようになる。   At this time, as shown in FIGS. 2 and 3, the ceiling wall 2a of the flexible stirring vessel 2 bends up and down, so that the drive shaft 3 can reciprocate such as up and down.

そして、完全密閉で摺動部のない雰囲気にて良好な流動作用を得られるようになる。   A good fluidity can be obtained in an atmosphere that is completely sealed and has no sliding parts.

また、上記ダメージ防止用板１６がない場合には、上記駆動軸３が往復動する際、この駆動軸３が固定された前記可撓性撹拌容器２の天井壁２ａの貫通孔４の縁部分のみに応力が集中するため、可撓性容器のように材質が弱いもの場合には、耐久性に問題が生ずる場合がある。   Further, when the damage prevention plate 16 is not provided, when the drive shaft 3 reciprocates, the edge portion of the through hole 4 of the ceiling wall 2a of the flexible stirring vessel 2 to which the drive shaft 3 is fixed. Since stress concentrates only on the surface, there may be a problem in durability when the material is weak like a flexible container.

そこで、本発明においては、ダメージ防止用板１６を設けるとともに、前記撹拌容器２内を陽圧とし、前記駆動軸３が下方に移動する場合には、前記天井壁２ａを該ダメージ防止用板１６の下面で押圧するようにして、天井壁２ａの一部に応力を集中させないようにし、また、前記駆動軸３が上方に移動する場合は、撹拌容器２内の陽圧により天井面２ａが上方に押し上げられるようにして、上記天井壁２ａの一部に応力が集中しないようにし、可撓性の容器であっても、その破損を防止でき、耐久性を上げることができるようになる。   Therefore, in the present invention, the damage prevention plate 16 is provided, and when the inside of the stirring vessel 2 is set to a positive pressure and the drive shaft 3 moves downward, the damage prevention plate 16 is placed on the ceiling wall 2a. So that the stress is not concentrated on a part of the ceiling wall 2a, and when the drive shaft 3 moves upward, the ceiling surface 2a is moved upward by the positive pressure in the stirring vessel 2. As a result, the stress is not concentrated on a part of the ceiling wall 2a, and even a flexible container can be prevented from being damaged and the durability can be increased.

また、駆動軸３は回転するものではないので、該駆動軸３に添加物供給手段を容易に設けることができ、前記撹拌容器２内に酸素などの気体や液体、又は固体などの添加物を供給できるようになる。   Further, since the drive shaft 3 does not rotate, an additive supply means can be easily provided on the drive shaft 3, and a gas such as oxygen, a liquid, or an additive such as a solid is placed in the stirring vessel 2. It becomes possible to supply.

また、本願発明は、回転軸を用いないことから、その取付公差の制約がなく、従って、前記可撓性撹拌容器２を往復動駆動装置に容易に脱着である。   In addition, since the present invention does not use a rotating shaft, there is no restriction on its mounting tolerance, and therefore the flexible stirring container 2 can be easily attached to and detached from the reciprocating drive device.

なお、前記実施例においては、駆動軸３を垂設し、上下方向に移動する例を示したが、駆動軸３を横設し、横方向に移動するなど、駆動軸を任意の方向に向け、該任意の方向に往復移動するようにしてもよい。   In the above-described embodiment, the example in which the drive shaft 3 is suspended and moved in the vertical direction has been described. The reciprocation may be performed in the arbitrary direction.

本発明の撹拌装置は、医療品関係、食品関係等における撹拌に利用される。   The stirring device of the present invention is used for stirring in medical products, foods, and the like.
