The object of the present invention is achieved like this:
It is mainly discharged system and weight balancing system etc. by body, operation control system, blood circuit system, fluid infusion system, waste liquid and partly forms.Wherein: body is made up of main frame, side lever and filter folder etc.; Operation control system is made up of Chinese operation control panel, LCDs and monitor key switch etc.; The blood circuit system is made up of transfusion filters, blood inflow pipe, blood effuser, blood pump, heparin pump, tremulous pulse air monitor, tremulous pulse bubble trap, arterial blood pressure monitoring device, venous air monitor, vein bubble trap, venous pressure monitor and flow plug etc.; Fluid infusion system is made up of fluid infusion pump, displacement liquid container, liquid supplementation pipe, displacement liquid cleaner and displacement liquid heater etc.; Waste liquid is discharged system and is made up of negative pressure pump, sewer pipe, transmembrane pressure monitor, blood leakage monitor and waste fluid container etc.; The weight balancing system is made up of weighing unit, LOAD CELLS, displacement liquid container, waste fluid container, fluid infusion pump and negative pressure pump etc.
Its structural feature is: described transfusion filters fixes on the side lever by the filter clamping, and the upper end of this transfusion filters links to each other with the blood effuser, and the lower end links to each other with the blood inflow pipe; The upper end of described liquid supplementation pipe links to each other with the vein bubble trap, and the lower end links to each other with the displacement liquid container; Described sewer pipe upper end links to each other with the side pipe mouth of transfusion filters, and the lower end of this sewer pipe links to each other with waste fluid container.Described waste fluid container and displacement liquid container are placed on the described weighing unit, and this weighing unit is placed on the described LOAD CELLS, and this LOAD CELLS links to each other with negative pressure pump with described fluid infusion pump by circuit; The weight balancing system determines ultrafiltration volume according to the variation of liquid gross weight on the described weighing unit, and with the ultrafiltration volume information feedback to described operation control panel.
Because transfusion filters is made up of a large amount of hollow fibre pipes, these hollow fibre pipes are a kind of semipermeable membranes with high-permeability, middle small-molecule substance can freely pass through, so blood under the effect of blood pump from pumping in patient's body after blood flows into pipe flow when transfusion filters filters, transfusion filters just can be with the metabolic waste in the blood (as creatinine, blood urea nitrogen, uric acid etc.), redundant moisture, harmful substances such as the exogenous or endogenous poisonous substance of inorganic salt and other filter away from blood with the waste liquid form, blood filters through the blood filter and purifies after monitor monitors flows back in patient's body from blood effuser safety, circulation so repeatedly realizes the purification to blood samples of patients.
Owing on the blood inflow pipe heparin pump is housed,, thereby has avoided blood extracorporeal circulation generation blood coagulation phenomenon so heparin pump can be injected anticoagulant in the blood inflow pipe with heparin solution (a kind of anticoagulant) automatically uniformly and stably.On blood inflow pipe and the blood effuser ultrasound wave air monitor and bubble trap are housed all, can effectively detect and remove air in the blood to avoid causing air embolism in the air admission patient body.
Side pipe mouth from transfusion filters under the effect of waste liquid at negative pressure pump that blood forms after the blood filter filters purification flows into sewer pipe, through transmembrane pressure monitor and blood leakage monitor monitoring, if transmembrane pressure is excessive, strides the film monitoring device and just can then
Send alarm and turn down the negative pressure pump rotating speed automatically to avoid the transfusion filters rupture of membranes, if blood will flow in the waste liquid behind the transfusion filters rupture of membranes, blood leakage monitor will send Lou blood alarm and interrupt run, to guarantee patient's safety, flows in the waste fluid container at last.
On the one hand since many uremias or acute renal failure patient in vivo because of there being a large amount of water retentions to form edema, therefore this class patient is when doing filtering therapy, need the moisture ultrafiltration of retention in the body is come out, to eliminate edema, we filter the moisture of retention and discharge the external process of patient ultrafiltration by transfusion filters, the amount of the water that ultrafiltration is come out is ultrafiltration volume.On the other hand since blood when filter filters, normal moisture in the blood and electrolyte will leach through the blood filter together along with harmful substance and form waste liquid, thereby normal moisture and electrolyte in the blood are lost in a large number, so blood needs to mend displacement liquid to replenish the normal moisture of losing and to keep electrolyte balance at blood effuser (or at blood inflow pipe) after the blood filter filters, fluid infusion, the amount of additional displacement liquid is amount infused this process for we.
It is by the fluid infusion pump displacement liquid to be pumped from the displacement liquid container that the benefit of displacement liquid is gone into, carry out flowing in the displacement liquid heater after the clean filtering through the displacement liquid cleaner again and heat, vein bubble trap from the blood effuser is added into and realizes in the blood at last so that the normal moisture that leaches from transfusion filters with mend the displacement liquid of going into and balance each other and keep electrolyte balance.
Therefore in the hemofiltration process, comprised the moisture that the displacement liquid mending and ultrafiltration go out in the waste liquid that leaches.In order both to guarantee that the moisture of retention in patient's body is discharged, guarantee that again the normal moisture that will lose adds in the blood, so hemofiltration must guarantee amount infused, waste liquid amount and ultrafiltration volume three's equilibrium relation, i.e. waste liquid amount=amount infused+ultrafiltration volume.Otherwise if the excessive waste liquid amount of amount infused too small (promptly occur negative ultrafiltration) then can make a large amount of moisture retentions in patient's body and cause occurring heart failure and pulmonary edema; Waste liquid amount excessive (being that ultrafiltration volume is excessive) can make the patient hypotension or shock occur because of a large amount of dehydrations if amount infused is too small; If patient's ultrafiltration volume is too small, the patient can not eliminate edema, and symptoms such as hypotension and dizziness can appear in the excessive patient of ultrafiltration volume.
Because the present invention has desk-top weight balancing system, can guarantee amount infused, waste liquid amount and ultrafiltration volume three's equilibrium relation, also can guarantee the equilibrium relation between fluid infusion pump and the negative pressure pump.After amount infused, ultrafiltration volume and filtration these three parameters running time are determined, the computer control system of operation control panel can calculate a corresponding fluid infusion pump speed and ultrasiltrated rate automatically, calculate the rotating speed of fluid infusion pump and negative pressure pump according to this fluid infusion pump speed and ultrasiltrated rate then, and it is satisfied automatically: waste liquid amount=amount infused+ultrafiltration volume.Because the difference of waste liquid amount and amount infused is exactly a ultrafiltration volume, and waste fluid container and displacement liquid container be placed on the same weighing unit, so the variable quantity of liquid gross weight is exactly a ultrafiltration volume on the weighing unit.For allow retention in patient's body moisture uniformly and stably ultrafiltration come out, the variable quantity that must make the gross weight of weighing unit is a direct proportion function relation of a time to time change.When too fast or slow excessively when ultrafiltration (be the total amount of liquid on the weighing unit change too soon or too slow), Weighing balancing system can arrive Chinese operation control panel with this information transmission automatically, the control system of operation control panel just can be sent instruction, adjusts the rotating speed of negative pressure pump automatically, till reaching balance.Therefore, desk-top weight balancing of the present invention system can guarantee accurately that fluid infusion, ultrafiltration and waste liquid discharge three's the speed and the balance of total amount, thereby has guaranteed the safety and the accuracy of hemofiltration running.
The present invention is if change transfusion filters into hemodialyzer, dialyser side pipe mouth is inserted in the liquid supplementation pipe upper end, can do hemodialysis: if change transfusion filters into blood perfusion device, can also do hemoperfusion, so the present invention can do hemofiltration and treats diseases such as uremia, acute renal failure, acute left heart failure and ascites recovery, also can treat chronic renal failure and uremia or treat diseases such as various poisonous substances, medicine and alimentary toxicosis by doing hemodialysis by doing hemoperfusion.Therefore the present invention is a kind of blood cleaning equipment that serves many purposes.
Adopt above scheme to have the following advantages:
1, the desk-top weight balancing of employing system can realize fluid infusion in the hemofiltration process, ultrafiltration and waste liquid discharge three's the speed and the equilibrium relation of total amount automatically, thereby has guaranteed the security reliability and the accuracy of hemofiltration process.
2, avoided the troublesome operation of the frequent shutdown replacing displacement liquid bag of employing coupling type weight balancing system mode.
3, increase automatons such as displacement liquid heater, displacement liquid cleaner, heparin pump and negative pressure pump, thereby improved the automatization of operating process.
4, increase safety monitoring devices such as blood leakage monitor, transmembrane pressure monitor, arterial blood pressure monitoring device, tremulous pulse bubble trap, thereby fully guaranteed the safety of hemofiltration process.
5, need not complexity, huge water treatment system, both simplified the structure, reduced cost again, be convenient to penetration and promotion in medical institutions at different levels.
6, can move arbitrarily, both can be used for the conventional blood purification treatment of Blood Purification Center, also can be used for the other emergency treatment of bed of ICU and emergency department.
