Embodiment Construction

[0022] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0023] figure 1 It is a schematic diagram of the structure of the blood purification pipeline in the prior art. One end of the first filter 5 in the device is directly connected with the outlet of the arterial pot 6, while the other end is directly connected with the inlet of the venous pot 4, and the outlet of the venous pot 4 is directly connected with the venous tube. Road 12 connects.

[0024] figure 2 The blood purification device comprises an arterial line 11, a venous line 12, a first filter 5 and a control unit (not shown in the figure); the arterial line 11 first passes through the arterial catheter clip 16 and then bypasses the blood pump 7 and the arterial jug The inlet of 6 is connected, and arterial conduit bypass 15 is provided on the arterial conduit 11 between blood pump 7 and arterial conduit clip 16; Venous conduit 12 is connected with the out...

Abstract

The invention discloses a blood purifier and a displacement method thereof. In the blood purifier, an artery pipe communicates with an artery kettle after bypassing a blood pump, and a vein pipe communicates with a vein kettle. A displacement liquid communicates with the vein kettle after bypassing a displacement liquid pump through pipes. A liquid waste output port of the blood filter communicates with a liquid waste collecting bag after bypassing a liquid waste pump through pipes. One in-film joint of the blood filter communicates with a first multi-pipe gating switch, and the other in-film joint of the blood filter communicates with a second multi-pipe gating switch. The first multi-pipe gating switch communicates with the vein kettle, and the second multi-pipe gating switch communicates with the artery kettle. Both the first multi-pipe gating switch and the second multi-pipe gating switch have ports connected with a blood filter to be replaced. The blood purifier and the displacement method thereof can solve the problems, such as blood exosmosis, increase of financial burden for a patient caused by frequently whole pipe replacement, influence on blood filtration, and increase of risk of blood infection, caused by direct separation of cruor in pipes during blood purification and installation of pipes and a blood filter.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for clinical blood purification. Background technique [0002] The scope of clinical application of continuous renal replacement therapy is expanding day by day, especially in the treatment of severe infection, trauma, poisoning and multiple organ failure and other critical diseases. In the prior art, there is a kind of continuous renal replacement therapy using Fresenius (Multifiltrate) CRRT machine, such as figure 1 As shown, patients often use continuous venovenous hemofiltration (CVVH) for therapeutic effect, but it is also time consuming. Not only that, repeated flushing of the pipeline can also be a pattern. Due to the long treatment time, there are many factors affecting the blood coagulation of the pipeline. Sometimes filter coagulation occurs after treatment for more than 10 hours. For patients receiving CRRT without anticoagulants, the treatment time w...
