Title:
DIALYSIS SOLUTION EXTRACTION DEVICE AND BLOOD PURIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/068320
Kind Code:
A1
Abstract:
Provided are a dialysis solution extraction device and a blood purification device, with which it is possible to reliably prevent the dispersal of a dialysis solution when removing a cap member from a collection opening part. The present invention is provided with: a dialysis solution extraction port 14 that has formed therein a collection opening part 14a through which a dialysis solution can be collected; a cap member 15 that can be attached to/detached from the collection opening part 14a of the dialysis solution extraction port 14; and a seal member 16 that seals the collection opening part 14a in a state in which the cap member 15 is attached to the collection opening part 14a. The seal member 16 comprises: an adhesion part 16a which adheres to the outer circumferential surface of the dialysis solution extraction port 14 so as to seal the collection opening part 14a; and a projection part 16b which is formed as to project toward the interior of the collection opening part 14a, and in which the outer circumferential surface 16ba thereof faces the inner circumferential surface 14aa of the collection opening part 14a so as to form a gap therebetween , and which forms an inflow passage γ that allows air from the outside to flow in when the seal by the adhesion part 16a is released.
