た。しかしながら、高周波融着を多用する従来の方法で
は生産性が悪く、効率的な生産が困難であり、その結果
製造コストも高くなる欠点を有していた。Usually, a blood transfusion set is provided with a filter for filtering blood and a drip tube for checking the blood transfusion rate. These filter bodies and drip tubes are generally integrated, and have conventionally been manufactured by high-frequency welding of synthetic resin tubes. However, conventional methods that make heavy use of high-frequency fusion bonding have the disadvantage that productivity is poor and efficient production is difficult, resulting in high manufacturing costs.

とする輸血用濾過点滴筒の製造法である。As a result of various studies to solve these problems, the inventor discovered that the purpose could be achieved by introducing a blow molding method, and thus arrived at the present invention. That is, the present invention involves a step of melt-extruding a synthetic resin to form a tube, and a step of blowing gas into the tube to expand it and bring it into close contact with a mold to form a continuous cylindrical body with alternating large-diameter portions and small-diameter portions. , the continuous cylindrical body is cut so that one end has a large diameter and the other end has a small diameter, and the large diameter part and the small diameter part are each divided into two parts.
a step of forming a separate cylindrical body; a step of inserting and fixing a tube having an outer diameter approximately equal to the inner diameter of the small diameter portion into the small diameter portion between the two large diameter portions of the cylindrical body; This is a method for producing a filtration drip tube for blood transfusion, which comprises a step of inserting and fusing a filter body and a tablet body or a tube for joining the tablet body from the diameter end.

定された状態を表わしている。1.1', 1"... or 2.2', 2", etc. may have exactly the same shape, but in order to manufacture the cylinder without waste, it is necessary that the two cylinders face each other. It is preferable that one unit is formed by combining the two, and this unit is repeated. That is, in FIG. 1, a portion separated by A-A and B-B and a portion separated by B-B and C-C are formed symmetrically with respect to line B-H,
By cutting AA, BB, and CC, the cylindrical body shown in FIG. 2 can be manufactured without waste. FIG. 2 is a perspective view of the cylindrical body thus obtained, which is formed of two large diameter sections 1.1' and two small diameter sections 2.2'. Next, in order to provide a drip port, a small diameter Iζ between the two large diameter parts 1 and 1' of the cylindrical body = B 2'? A tube 3 having an outer diameter approximately equal to the inner diameter of the small diameter portion is inserted and fixed by adhesive or the like. FIG. 2 shows the tube 3 in a fixed state.

The ends are fused together with the filter body and the lock body to form a filtration chamber. The fusion is preferably performed by high frequency heating. FIG. 3 is a front view showing one embodiment of the filtration drip tube obtained in this way, and 6 is the hlI11 fitting part. In addition, in the case shown in FIG. 8, the lock body is directly fixed to the filtration drip tube, but it may be connected via a tube. In this case, a tube for connecting the filter body and the lock body is inserted into the cylindrical body and fused.
