製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing a medical bag for storing and preserving glucose, amino acids, Ringer's, physiological saline, blood preservation solution, blood, and the like.
（従来の技術及び問題点）
血液の保存、成分分離などに軟質塩化ビニル製の血液バ

血口３３などが取付けられている。For example, as shown in FIG. 3, this blood bag has a connection tube 30 for connecting to another bag, a blood collection tube 31, a blood transfusion port 33 covered with a protector 32, etc. attached to the upper end of the bag.

る。In order to attach these parts, conventionally, as shown in Fig. 4, two plastic sheets 3 are used to form the bag.
Insert the blood transfusion port 33.33 and the tubes 30a, 31a of each tube 30.31 into the end edge of the tube 4.34, and perform high-frequency welding of the conductive material as shown in FIG. While inserting the core pin 35, a high frequency welding mold 37.37 having a straight tubular groove 36.36 slightly smaller than the sum of the diameter of the cylinder 38 and the thickness of the sheet 34 is inserted into the sheet 34. It was pressed and welded from .34.

。However, according to this method, the constituent materials of the fused cylinder and sheet are forcibly pushed out beyond the welded seal between the cylinder and the sheet, resulting in a water droplet-shaped burr 39 as shown in FIG. as it protrudes into the internal space of the bag or protector. In particular, if a water droplet-shaped burr 39 forms inside the bag, blood may remain in the narrow part formed by the burr, the opening area of each cylinder becomes narrower, making it difficult to flow in and out, and blood cells may be damaged. This may cause problems such as On the other hand, the burr 39 on the outside of the bag may lead to a puncture failure of the protector 32.

題もあった。Also, compared to the flexible thin sheet 34, the cylinder 38
has a thick wall and relatively high rigidity, so if you try to completely weld the sheet and cylinder while heating them, the fusion will occur at the lower end of the cylinder as shown in Figure 7. There are also problems in that the dressing sheet becomes thinner, has a fragile portion 40, becomes easily damaged, and even has pinholes.
このような減少は、プロテクター３２の内面部にも生じ

った。Such a reduction also occurred on the inner surface of the protector 32, and there was a risk that the fragile portion would be damaged and the blood transfusion port would be contaminated.

バッグの製造方法が記載されている。Recently, Japanese Patent Application Laid-open No. 58-165867 discloses a mold in which a first land 41 for primary welding of resin, a second land 42 for secondary welding, and a third land 43 are formed, as shown in FIG. The tube 46 fitted into the core pin 45 and the sheet 47.47 are interposed between the tube 46 and the sheet 47.47, and a mold 44.44 is pressed against the tube 46 and the sheet 47.47, and a high frequency is applied to the tube 46 and the sheet 47.47. The constituent materials of the sheets 47 and 47 are melted and the welded constituent materials of the tube 46 and the sheets 47 and 47 are flowed out from the first land 41 to both sides of the first land 41, and the constituent materials of the tube 46 and the sheets 47 and 47 are melted to the first land 41. The secondary fusion is formed by absorbing and filling the primary fusion part 50 and the small space 47 formed between the tube 46 and the sheets 47 and 47 on both sides thereof without exceeding the lowest end 48 of the sheet fusion seal part. A method of manufacturing a medical bag forming section 51 is described.

していた。This method is an excellent invention since the constituent materials of the tube 46 and the sheets 47 and 47 do not flow out beyond the lowest end 48 of the sheet fusion seal portion, so no burrs are generated on the inner surface of the medical bag. It is difficult to adjust so that the fused portion 51 is completely filled with the molten resin, and as shown in FIG. However, there was some blood left in this area.

。(Means for solving the problems) As a result of intensive studies to solve the above problems,
It has been found that the above problems can be solved by forming a non-mating part 14 between the base part 4 of the opening part 3 of the medical bag and the plastic sheet 5.6. Specifically, the base 4 of the mouth molded product 3 of the medical bag is attached to the core pin 1 whose tip is capped with a non-conductive material 2 so that it covers the non-conductive material 2 within a range of 2 to 5 cm. After that, the mouth molded product 3 is sandwiched between two plastic sheets 5.6, and these sandwiching members are further clamped by a mold 9.10 having a straight sheet suppressing portion 7.8. A method of manufacturing a medical bag is provided in which a non-welded portion is formed between the base portion 4 and the plastic sheet 5.6.
（実施例）

図である０図中１は鉄、ステンレス、黄銅、ジュラルミ
ン等の導電性材料からなるコアピンで、その先端には例
えば、テフロン、ベークライト、セラミック、等からな
る非導電性材料２が装着されている。(Example) Figure 1 is a schematic diagram showing the method for manufacturing a medical bag of the present invention. In Figure 0, 1 is a core pin made of a conductive material such as iron, stainless steel, brass, duralumin, etc. A non-conductive material 2 made of, for example, Teflon, Bakelite, ceramic, etc. is attached.
最初に、コアピンｌに医療用バッグの口部成形品３を該
口部成形品３の基部４が幅Ａの範囲でかかるように装着
する。First, the mouth molded product 3 of the medical bag is attached to the core pin 1 so that the base 4 of the mouth molded product 3 covers the width A.
続いて、口部成形品３を装着したコアビン■を２枚のプ

成形品３とプラスチックシート５．６を溶着する。Next, the core bin ■ with the mouth molded product 3 attached thereto is sandwiched between two plastic sheets 5.6, and then, while applying high frequency, a mold in which the sheet suppressing portions 7.8 are formed flat from above and below is formed. 9. By clamping from step 10, the mouth molded product 3 and the plastic sheet 5.6 are welded.

融せず、金型９．１０のクランプ圧によりシート５．６
の内部空間１１方向へ移動しようとする前記溶融した構
成材料の移動を抑止する役割を果す。In other words, the constituent materials of the mouth molded product 3 and the sheet 5.6 that are in contact with the conductive member of the core pin 1 are melted by heat, and the base of the mouth portion 3 that is in contact with the non-conductive material 2 is melted by the heat. 4 and sheet 5.6 do not melt because heat is not directly transferred to them, and sheet 5.6 is formed by the clamping pressure of mold 9.10.
This serves to prevent the molten constituent material from moving toward the interior space 11 of the molten material.
第２図は、以上のようにして形成した医療用バッグの溶
着部付近の拡大図を示す。FIG. 2 shows an enlarged view of the vicinity of the welded portion of the medical bag formed as described above.
１２．１３は、コアピン１と金型９．１０により溶融さ
れた溶着部で、１４は、非導電性部材２により当接され
ていたために溶着されなかった非融着部である。Reference numeral 12 and 13 denote a welded portion that is melted by the core pin 1 and the mold 9 and 10, and 14 is a non-fused portion that was not welded because it was in contact with the non-conductive member 2.
非融着部１４の輻Ｂは、第１図で示したようにコアピン
ｌの非導電性材料２に、口部成形品３の基部４をかけた
幅Ａに相当する。The convergence B of the non-fused portion 14 corresponds to the width A obtained by multiplying the non-conductive material 2 of the core pin 1 by the base 4 of the mouth molded product 3, as shown in FIG.
幅Ａの範囲は２〜５ｍｍが好ましい、２ｍｍ以下では、
溶着時に溶融した構成材料の移動を抑制する役割を充分
に果すことができず、シート５．６の内部空間１１にパ
リが生成するので好ましくない。The range of the width A is preferably 2 to 5 mm, and if it is 2 mm or less,
This is not preferable because it cannot sufficiently suppress the movement of the melted constituent materials during welding, and particles are generated in the internal space 11 of the sheet 5.6.
５ｍｍ以上では、非融着部１４のシートと口部成形品３
との間に液体が多くしみ込み滞留することとなり好まし
くない、また運搬中や使用中に外圧が加わった時、該非
融着部に応力が集中してめくれの原因となり、著しく強
度が低下する。If it is 5 mm or more, the sheet of the non-fused part 14 and the mouth part molded part 3
This is undesirable as a large amount of liquid will seep in and stay between the parts, and when external pressure is applied during transportation or use, stress will concentrate on the unfused parts, causing them to curl up and significantly reduce the strength.

Since it is in close contact with the formation amount between 3 and 3, the amount of liquid that seeps into the contact area is minute, and there is no welding burr, so blood,
The chemical solution, etc. can be discharged smoothly.
