Problems solved by technology

[0003] In the above-mentioned medical bag unit, the transfer channel is formed by thermally welding two sheets of film to each other, so the liquid medicine flow path may be blocked due to the restoring force of these sheets.
If so, it may not be possible to make the liquid medicine flow smoothly in the liquid medicine flow path.

[0036] The medical bag unit 10A of the present embodiment is configured as an infusion bag unit for administering an infusion solution (medicine solution M) into a living body through, for example, a height difference of the transfer line 18 . Among them, the medical bag unit 10A may also be configured as a nutrient that introduces the nutritional agent (medicine solution M) into the digestive organs through a tube inserted into a small hole such as a gastric fistula, nasal cavity, or intestinal fistula through the drop of the transfer pipeline 18, for example. bag unit.

[0037] Such as figure 1 As shown, the medical bag unit 10A is provided with: a bag main body 14 having a storage portion 12 containing a medical solution M; a transfer line 18 formed with a medical solution flow channel 16 communicating with the inside of the storage portion 12; 18 connector 20; and a cap 22 provided on the connector 20.

[0038] The bag main body 14 and the transfer line 18 are formed by ...

[0064] Next, the medical bag unit 10B and its manufacturing method according to the second embodiment of the present invention will be described. In addition, in the medical bag unit 10B of the second embodiment, the same reference numerals are assigned to the same components as those of the medical bag unit 10A of the first embodiment, and detailed description thereof will be omitted. The same applies to the third embodiment described later.

[0065] Such as Figure 7 As shown, the medical bag unit 10B of this embodiment has a rectangular seal portion 60 . In other words, the width dimension of the bag main body 14a is set to be the same as the width dimension of the transfer line 18b (width dimension L1). In addition, the width dimension and length dimension of the bag main body 14a are set to be the same as the width dimension and length dimension of the above-mentioned bag body 14, and the length dimension and inner width dimension of the transfer line 18a are set to be ...

no. 3 approach

[0070] Next, the medical bag unit 10C and its manufacturing method according to the third embodiment of the present invention will be described.

[0071] Such as Figure 9 with Figure 10 As shown, the medical bag unit 10C of this embodiment includes a bag main body 14 b and a transfer line 18 . In addition, the width dimension and length dimension of the bag main body 14b are set to be the same as the width dimension and length dimension of the bag main body 14 mentioned above. Each side seal part 24b, 24c of the bag main body 14b protrudes to the other end side (Y2 direction) rather than the side part 12b of the accommodating part 12. As shown in FIG. Each intermediate seal part 24d, 24e is connected at the position shifted by predetermined length from the other end part of each side seal part 24b, 24c toward the one end side (Y1 direction) where the hole part 25 exists.

[0072] In addition, the medical bag unit 10C has a pair of support parts 66 and 68 that connect the ...

Abstract

This medical bag unit (10A) is provided with a bag main body (14) which contains a drug solution (M), and with a transfer line (18) which comprises film portions (15a, 15b) which are provided integrally with the bag main body (14), overlap each other and are bonded together so as to form a drug solution flow path (16) that communicates with the inside of the bag main body (14). The first flow pathfilm portion (15a) configuring the drug solution flow path (16) has a bulging portion (26) bulged to the side opposite of the second flow path film portion (15b) such that the inner surface of said first flow path film portion (15b) is formed concavely.

Description

technical field [0001] The present invention relates to a medical bag unit including a bag body containing a medical solution and a transfer line provided integrally with the bag body, and a method for manufacturing the same. Background technique [0002] Conventionally, a medical bag unit has been used in which a drug solution in a bag main body is supplied to a living body by circulating the drug solution in the drug solution flow path of the transfer line. In such a medical bag unit, for example, Japanese Patent No. 4658570 discloses that the bag body and the transfer line are integrally formed by overlapping two sheets of polymer material and thermally welding these sheets. technical thinking. [0003] In the medical bag unit described above, since the transfer channel is formed by thermally welding the two sheets to each other, the medical solution flow path may be clogged due to the restoring force of these sheets. If so, there is a possibility that the medical solut...
