Another insert piece for blood tubing set to promote mixing infusion solution with further fluid

Abstract

Another insert piece for a blood tubing set to promote mixing an infusion solution with a further fluid The present invention relates to an insert piece (100) for a blood tubing set (200), comprisingblood tubing set (200), comprising at least, respectively, a first connection site (101) for connecting a first tubing portion (205a) of the blood tubing set (200) to the insert piece (100); a secondconnection site (103) for connecting a second tubing portion (205b) of the blood tubing set (200) to the insert piece (100); a third connection site (105) for connecting a third tubing portion (209) of the blood tubing set (200) to the insert piece (100); a first main line (107a) for conducting a first liquid, preferably blood, through the insert piece (100), wherein the first main line (107a) isin fluid communication with the first connection site (101) and with the second connection site (103); a second main line (107b) for conducting a first liquid, preferably blood, through the insert piece (100), wherein the second main line (107b) is in fluid communication with the first connection site (101) and with the second connection site (103); a secondary line (111) for conducting a second liquid, preferably an infusion, into at least one of the first main line (107a); the second main line (107b); the secondary line (111), and a connection portion (109) which connects both main lines (107a, 107b) to each other or to the second connection site (103); wherein the secondary line (111) is in fluid communication with the third connection site (105); the first connection site (101) comprises a perfusable lumen having a first cross section area; the second connection site (103) comprises a perfusable lumen having a second cross section area; and the first main line (107a) and/or the second main line (107b) comprises a perfusable lumen having a third cross section area.

Description

technical field [0001] The invention relates to an insert according to the preamble of claim 1 , an extracorporeal blood tube set according to the preamble of claim 11 and a blood treatment device according to the preamble of claim 15 . Background technique [0002] During extracorporeal blood therapy, infusion solutions or drugs are mostly infused through the extracorporeal blood circuit, ie the blood tubing system utilized. Depending on the type of infusion solution, rapid mixing of the infusion solution with blood may be beneficial or desirable. [0003] For example, anticoagulant infusion solutions are regularly infused during extracorporeal blood therapy to prevent possible blockage of extracorporeal blood circulation. [0004] Two methods are mainly used for this purpose; systemic anticoagulation and local anticoagulation. A citrate solution that complexes calcium to inhibit blood coagulation is mainly used as an anticoagulant in partial anticoagulation. Additional ...
