Abstract

PURPOSE:To efficiently perform the shaping of a tube connection part after the connection of tubes by providing a tube shaping part molding the connection part of flatly deformed tubes to allow the cavities of the tubes to communicate each other to the lid member of one of first and second tube holders. CONSTITUTION:The connection part 93 of connected tubes 91, 92 is moved to the position corresponding to the protruding part 71 in a groove 21 to be rotated to set the flatness of the connection part 93 to a vertical direction. When the lid member 24 of a first tube holder 2 is closed, the protruding part 71 formed to the inner surface of the lid member 24 presses the flat connection part 93 from the vertical direction to shape the connection part 93 desirably. By this constitution, the mutual welding of the inner surfaces of the tubes at the connection part 93 is released and the cavities of the tubes 91, 92 communicate each other. Since the connected tubes 91, 92 are fixed by a second tube holder 3 in tube shaping work, the connection part 93 can be certainly shaped and the cavities of both tubes can be allowed to communicate each other.

て抜き取り、両チューブを融着するものである。This tube connecting device is provided with a pair of holders (blocks) capable of holding two tubes to be connected in parallel with each other, and a wafer (a plate-shaped plate) installed between the holders and movable across the tubes. Heating element) and heating the wafer while moving the two tubes while holding the two tubes in parallel and in opposite directions in the grooves formed in both holders. Melt and cut, then move one holder in the tube radial direction (arranged direction) to match the cut ends of the tubes to be joined, move to the wafer retreat position and remove, and fuse both tubes It is a thing.

る。By the way, the tube connecting portion connected by such a tube fusing device is deformed into a flat shape because the inner surfaces of the tubes are partially adhered to each other when the wafer is pulled out, and the tube inner cavity is deformed. Will be blocked. Therefore, after the tube connection, it is necessary to remove the part where the inner surfaces of the tubes are adhered (fused) to each other, and to perform the operation of communicating the tube lumens (tube shaping operation).

差し指とでチューブ接続部を挟み、これを押し潰しつつ
両指の間で転がしてもみほぐし、チューブ内面同士の接
着を剥していた。Conventionally, in this tube shaping operation, a tube connecting portion is sandwiched between a thumb and an index finger, and the tube inner portion is loosened by crushing the tube connecting portion and rolling it between the fingers so as to remove the adhesion between the inner surfaces of the tube.

率が低いという欠点もある。However, immediately after the tube is connected, the heat generated when the tube is melted remains, so there is a risk of burns if the work of unraveling with a finger is performed. It was hanging. Further, such a manual work has a drawback that the operation rate of the tube connecting work is low.

い。It is also possible to perform a tube shaping operation by using a predetermined tube shaping instrument or device, instead of directly gripping the tube with a finger. In this case as well, after connecting the tube, the tube shaping operation is performed. The work of transporting to an orthopedic device and the like and the work of loading the work are required, and the work is time-consuming and time-consuming, and eventually the above-mentioned drawbacks cannot be solved.
