Technical Field

[0001] The utility model relates to the technical field of tube-sealing liquids, in particular to a disposable tube-sealing liquid bag. Background Art

[0002] After an infusion or hemodialysis session, blood can easily flow back into the central venous catheter or hemodialysis catheter, clogging it and causing coagulation. Therefore, a sealing solution containing an anticoagulant is required. This solution is injected into the vein after the infusion to prevent clogging of the intravenous catheter. It is crucial for maintaining smooth infusion and primarily contains sodium heparin and normal saline.

[0003] The Chinese patent publication number is CN113633883A, and the authorization announcement date is November 12, 2021.
