Abstract
The invention discloses a blood purifier. The blood purifier comprises an artery pipe, a vein pipe and a blood filter. The artery pipe communicates with an artery kettle after bypassing a blood pump, and the 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 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
The present invention relates to technical field of medical instruments, especially a kind of clinically for the device of blood purification.
Background technology
Continuous renal replacementtherapy clinical application range, at expanding day, especially plays important effect in the treatment of the critical illnesses such as severe infections, wound, poisoning and MOFE.What have a kind of continuous renal replacementtherapy to adopt in prior art is Fei Senyousi ﹙ Multifiltrate ﹚ CRRT machine, as shown in Figure 1, patient commonly uses the Therapeutic mode of Continuous Veno-venous Xue liquid Lv Guo ﹙ CVVH ﹚, because treatment time is long, affecting pipeline coagulation factor more, just there is blood filter blood coagulation in 10 several hours in treatment sometimes, for without anticoagulant row patient CRRT, treatment time can be shorter, and the position that blood coagulation the most often occurs in blood purifying pipeline is blood filter, is secondly venous chambers.During without anticoagulant, for preventing pipeline blood coagulation and extending the blood filter life-span, often take be interrupted normal saline flushing pipeline and improve the measures such as rate of blood flow, but all difficulty achieves the goal; And change the financial burden that a whole set of pipeline had both increased patient frequently, affect again the therapeutic effect of hemofiltration, also lose time simultaneously.Moreover, repeated multiple times flushing of pipeline also can increase the risk of blood infection.If pipeline directly replaces the blood filter of blood coagulation outward, at the outer pre-flush blood filter of pipeline, easily contaminated, be separated simultaneously and installation pipeline and blood filter time, also easily generation blood extravasation and pollution.If the blood filter of blood coagulation can be replaced before finding the complete blood coagulation of blood filter, so just can re-establish CRRT treatment, both for patient reduces the financial burden, can resume treatment rapidly again.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of apparatus for purifying blood, it can solve in blood samples of patients purification process due to pipeline blood coagulation need be separated with installation pipeline and blood filter time, easy generation blood extravasation and pollution and frequently change the financial burden that a whole set of pipeline had both increased patient, affect again the therapeutic effect of hemofiltration and increase the problem of blood infection risk.
In order to solve the problem, technical scheme of the present invention is: this apparatus for purifying blood comprises arterial line and venous line and the first blood filter and control unit; Described arterial line is walked around blood pump and is connected with the entrance of tremulous pulse kettle, and described venous line is connected with the outlet of the first venous chambers; Displacement liquid is walked around displacement liquid pump by pipeline and is connected with the entrance of described first venous chambers; The waste liquid delivery outlet of described first blood filter is walked around waste drains pump by pipeline and is connected with liquid waste collector; Described blood pump, displacement liquid pump and waste drains pump are electrically connected with described control unit respectively by wire; A film nipple of described first blood filter is communicated with the first multi-channel gating switch, and another film nipple is communicated with the second multi-channel gating switch; Described first multi-channel gating switch is connected with the entrance of described first venous chambers, and described second multi-channel gating switch is connected with the outlet of described tremulous pulse kettle; Described first multi-channel gating switch and described second multi-channel gating switch are all reserved with the port of the temporary close be connected with the second blood filter waiting.
Another program is: the entrance of described first venous chambers of this apparatus for purifying blood is communicated with the 3rd multi-channel gating switch, and the outlet of described first venous chambers is communicated with the 4th multi-channel gating switch; Described 3rd multi-channel gating switch is connected with described first multi-channel gating switch, and described 4th multi-channel gating switch is connected with described venous line; Described 3rd multi-channel gating switch is all reserved with the port of the temporary close be connected with the second venous chambers waiting with described 4th multi-channel gating switch.
In technique scheme, more specifically scheme can also be: described first multi-channel gating switch, described second multi-channel gating switch, described 3rd multi-channel gating switch and described 4th multi-channel gating switch are knob three way cock.
Further: described blood pump, displacement liquid pump and waste drains pump are medical peristaltic pump.
Owing to adopting technique scheme, the present invention has following beneficial effect:
1, the present invention can select whether replace blood filter, flexible and convenient according to the practical situation of blood purification process; When blood coagulation appears in blood filter, replace the blood filter of blood coagulation in time with new blood filter, adopt closed filter to rush in advance, can avoid infection, set up treatment rapidly.
2, adopt the present invention can recover rapidly CRRT treatment, reach better therapeutic effect.
3, the present invention avoids changing a whole set of pipeline, and for patient reduces the financial burden, simultaneously because avoid the replacing of a whole set of pipeline, reduce the probability infected, program is simpler simultaneously, for medical worker saves time, realizes the cost degradation of blood purification treatment.
