法及び装置に関する。Description: TECHNICAL FIELD The present invention relates to a high-frequency fusion method and apparatus for a heat-fusible tube containing blood or an aqueous solution, and in particular, high-frequency power is externally output as high-frequency noise during high-frequency fusion. The present invention relates to a high-frequency fusion method and apparatus for preventing propagation and damage to surrounding electronic devices.

〔従来の技術〕[Conventional technology]

従来、採血した血液バッグの熱融着性チューブを高周波
融着する場合、高周波雑音が発生し、周囲の電子機器に
障害を与えるため、この高周波雑音の外部への伝搬を防

周囲を部分的に金属等の導電性材料で囲う方法が採られ
ている。Conventionally, when the heat-fusible tube of a blood bag that has been collected is subjected to high-frequency fusion, high-frequency noise is generated and damages electronic devices in the surroundings.Therefore, as a means for preventing the propagation of this high-frequency noise to the outside, A method is used in which the entire fusing device and the fusing electrodes are partially surrounded by a conductive material such as metal.

〔発明が解決しようとする課題〕[Problems to be Solved by the Invention]

しかし、このような従来の高周波融着装置を用いても、
チューブ内に血液又は電解質溶液が存在する場合は、血

う問題があった。However, even if such a conventional high-frequency fusion device is used,
When blood or electrolyte solution is present in the tube, there is a problem that the blood or electrolyte solution acts as an antenna, radiates high frequency noise to the outside, and causes damage to electronic devices in the vicinity.

したがって、本発明はチューブ内に血液又は電解質溶液
が存在する場合でも高周波雑音の外部への伝搬を実質的
に防止し得るチューブの高周波融着方法及びそのための
装置を提供することを目的とする。Therefore, it is an object of the present invention to provide a tube high-frequency fusion method and a device therefor, which can substantially prevent high-frequency noise from being propagated to the outside even when blood or an electrolyte solution is present in the tube.

〔課題を解決するための手段〕[Means for Solving the Problems]

即ち、本発明は上記目的達成のための手段として、血液
又は電解質溶液を含む熱融着性チューブの一部を一対の

状態で高周波融着をおこなうことを特徴とする熱融着性
チューブの高周波融着方法を提供するものである。That is, the present invention, as a means for achieving the above object, sandwiches a part of a heat-fusible tube containing blood or an electrolyte solution with a pair of fusion electrodes, and applies a high-frequency electrode to the electrodes to apply high-frequency fusion. In the method described above, the tube portions on both sides of the fusion-bonded portion are each closed by a clamp member to cut off the internal passages thereof to divide the blood or electrolyte solution contained in the tube, and high-frequency fusion is performed in that state. A high-frequency fusion method for a heat-fusible tube is provided.

さらに、本発明は上記方法を実施する為の装置として、
血液又は電解質溶液を内部に有する熱融着性チューブの
導入部両側に互いに対向して接近自在に設けられた一対
の融着電極と、該チューブ導入部に沿って該融着電極の
両側に該融着電極から若干離間させて設けられ、該チュ

一対のクランプ部材とを具備してなる高周波融着装置を
提供するものである。Furthermore, the present invention provides an apparatus for carrying out the above method,
A pair of fusion electrodes, which are provided so as to be opposed to each other on both sides of the introduction portion of the heat-fusible tube having blood or an electrolyte solution therein, and the fusion electrodes on both sides of the fusion electrode along the tube introduction portion. The present invention provides a high-frequency fusion device including a pair of clamp members which are provided slightly apart from a fusion electrode and which can appropriately close the internal passages of the tube.

なお、上記高周波融着方法および装置において、クラン
プ部材は金属から構成されていて、かつ接地させるよう
にすることがより好ましい。In the high frequency fusion welding method and apparatus, it is more preferable that the clamp member is made of metal and is grounded.

外部への伝搬を効果的に防止することができる。According to the method and apparatus for high-frequency fusion of the heat-fusible tube of the present invention, the tube portions on both sides of the tube fusion part are closed by the clamp members to divide the blood or electrolyte solution in the tube, and the high-frequency fusion is performed in that state. Since the adhesion is performed, it is possible to prevent the blood or electrolyte solution in the tube from acting as an antenna, and thus to effectively prevent the propagation of high frequency noise to the outside.

The risk of rupturing a part of the expanded and softened tube can be prevented.

１を定常状態より押し潰す。First, after introducing the tube 1 (wall thickness, for example, 0.5 mm) to be fused having blood or electrolytic solution inside into the groove 17, first, as a first step, the pushing plate 12 is pushed, and The stopper 7 is pressed by this, the clamp spring 6, the clamp spring 11 and the clamp spring 9 are slightly contracted by this, and the fusion positive electrode 2a slides in the axial direction of the shaft 4 and the fusion negative electrode 2b. Crush tube 1. In this case, the front surface of the fusion positive electrode 2a is the front surface 1 of the side of the escape frame 14.
It moves forward until it contacts 4a, 14b. At this time,
The clamp block 10 moves together with the fusion positive electrode 2a,
The tube 1 between the escape frame 14 and the clamp claw 16 is crushed from the steady state.

ラケット５外方のチューブに流出する（第６図）。In the second stage, the push plate 12 is further pushed, which pushes the stopper 7 further forward, and further contracts the clamp spring 6, the clamp spring 11, and the clamp spring 9. The fusion positive electrode 2a further pushes the escape frame 14 and slides the escape frame 14 in the horizontal direction until the partial tube 1 between the fusion negative electrode 2b and the fusion negative electrode 2b is completely crushed. At this time, the distance between the fusion-bonding positive electrode 2a and the fusion-bonding negative electrode 2b is the tube wall thickness of about 1.0 mm. On the other hand, the clamp block 10 also slides together with the fusion positive electrode 2a to further crush the tube 1 between it and the clamp claw 16. However, the clamp claw 16
Since the tube 1 is not yet completely closed in the area of, even if the volume in the tube 1 is reduced by the amount crushed by the electrodes 2a and 2b, the solution in the tube 1 corresponding to that amount is outside the bracket 5. Out of the tube (Fig. 6).

Therefore, only the clamp block 10 slides by the force of the clamp spring 11, and the space between the clamp block 10 and the clamp claw 16 is increased. Completely crush tube 1 of. At this time, the distance between the clamp block 10 and the clamp claw 16 is about 1 mm, which corresponds to the thickness of the tube 1 (No. 7).

るしく抑制することが可能となる。In the fourth stage, a high frequency voltage is applied to both electrodes 2a and 2b, and the tube 1 is fused. The inner volume of the tube 1 decreases as this fusion proceeds, but the tube 1 between the clamp block 10 and the escape frame 14 is reduced in the first step.
Is crushed more than in the steady state, and the distance between the clamp block 10 and the escape frame 14 can be widened, so that the decrease in the inner volume of the tube 1 is absorbed and there is no fear of the tube 1 rupturing (No. (Fig. 8). Further, the propagation of high-frequency noise can be significantly suppressed because the tube 1 is completely closed by the clamp block 10 and the clamp claws 16 in the third step, and the antenna action due to blood and electrolyte solution is lost. It will be possible.

周波雑音の漏洩も低減できる。Furthermore, since both electrodes 2a and 2b are also surrounded by a metal bracket 5 (for example, a Cu-underlying Ni-plated product) that is grounded, leakage of high frequency noise can be reduced.

When it becomes about 0 mm, the high frequency voltage is cut off, and after a certain cooling time, the pressing by the pressing plate 12 is released and the clamp spring 6 returns to the initial state.
