Port member for infusion bag, and infusion bag

Abstract

Provided a port member for an infusion solution bag that is capable of suppressing occurrence of gaps or wrinkles in a sealed portion in a manufacturing process, and preventing damages to resin sheets of a bag body during storage or transportation. A port member for an infusion solution bag includes a tubular body portion having one end sealed by a plug member structured to enable a hollow needle to be pierced into the plug member, and a tubular to-be-sealed portion continuously formed with an other end of the body portion and having an inner space communicated with the inside of the body portion, the to-be-sealed portion being held between and sealed to end portions of resin sheets overlapped together to form a bag body having an inner space for accommodation of at least a medicine, in which the to-be-sealed portion thus sealed has a radially flattened shape.

Description

technical field [0001] The present invention relates to a port member for an infusion bag that is fluidly connected to a bag body formed with an inner space for storing at least medicines, and an infusion bag including the port member. Background technique [0002] Conventionally, various containers have been provided as containers for accommodating various medicines. As one of them, there are known Figure 11 (a) shows the infusion bag 5 comprising the bag body 50 and the inlet and outlet part 51 fluidly connected with the bag body 50, wherein, by sealing the overlapped resin sheets S, ends (peripheral ends) E, E of S, the bag The main body 50 forms an internal space 500 for storing at least medicine. [0003] The access part 51 includes a cylindrical body part 511 whose end is closed by a plug body 510 that can be pierced by a hollow needle N, and a cylinder that is connected to the other end of the body part 511 so that the inside communicates with the inside of the body ...

AI Technical Summary

Problems solved by technology

[0008] This will cause: at the border of the sealing portion between the resin sheets S, S and the sealing portion between the resin sheets S, S and the sealed portion 512 or in the vicinity thereof, wrinkles W are formed on the resin sheets S, S (see Figure 11 (a)) or form a small gap G (see Figure 11 (b)), so that it is not only unsightly as a product, but also the medicine may leak from the part of the fold W or the gap G

[0009] Moreover, since the bag body 50 is made of freely deformable resin sheets S, S, when the infusion bag 5 is stored or transported, sometimes the bag body 50 containing the medicine may be folded (such as a half-folded state). The sealed portion 512 is formed in a cylindrical shape, so the portion EP of the bag body 50 corresponding to the opening end edge portion of the sealed portion 512 will be in a protruding (cornered) state, and since the bag body 50 is folded, the protruding portion EP and It is also possible to open holes in the resin sheet S, S due to partial contact with the opposite part
