Description
The present invention relates to a kind of serial armarium, particularly a kind of serial automatic hemo-dialyser.The present invention is suitable for medical institutions at different levels and is used for the treatment of acute renal failure, chronic renal failure with uremia, and the multiple organ failure, MOF accompanies renal failure, poisonous substance, drug intoxication etc.
Present conventional artificial kidney machine has many shortcomings: 1, cost an arm and a leg.2, volume heaviness can not be moved patient's other treatment of bed according to patient's the state of an illness to temporarily.3, the conventional artificial kidney machine of dependence water source, power supply, import is higher to water, power requirement, and water, power supply hypotony all can not be moved, out of service at once can not the treatment of cutting off the water.4, dialysis solution is one-way flow, disposablely promptly dumps without abundant application by dialyser, causes energy waste.5, side reaction is big, and unbalanced syndrome takes place in the treatment, hypotension, even shock.External portable, Wearable artificial kidney, its basic scheme is that conventional artificial kidney machine's automatic monitoring system is partly dwindled, use the dialysate regeneration device and dwindle the dialysis solution feed system, as the REDY system, the mode that dialysis solution circulates in dialyser is the same with traditional conventional artificial kidney machine, is one-way flow.The the lighter of external Wearable artificial kidney total amount is 4.5 kilograms, relies on the power supply of battery or external power supply.Because imperfection own is not popularized the domestic Wearable artificial kidney application report that does not have import so far up till now yet in a large number.Continuous arterio venous hemofiltration (CAVH), though the other treatment of feasible bed accompanies the renal failure patient to offer convenience to treatment acute renal failure, chronic renal failure with uremia, multiple organ failure, MOF,, CAVH still has its shortcoming: 1, micromolecule is removed rate variance; 2, need in the treatment to replenish a large amount of displacement liquids and easily cause severe infections, and treat the cost height; 3, only can lie in bed and carry out.Continuous arterio venous hemofiltration dialysis (CAVHD) has improved the part curative effect of CAVH, but its shortcoming is: 1, dialysis solution still imitates traditional flow and method, is one-way flow, and per minute 15ml, disposable application dialysis solution be waste still.2, treatment time is long, easily concurrent hemorrhage.3, only can lie in bed and treat.United States Patent (USP), the patent No.: 4.631050.Int.Cl
4.A61M1/03。By " the defeated automatically streaming system and the method " of invention such as Charles C.Reed mainly by three impeller pumps, two filter unit and ultrafiltration unit and tubing and constitute, and are used for the cleaning from body blood of wound, operation, concentrate, feed back, can not carry out hemodialysis.United States Patent (USP), the patent No.: 4,650,457.Int.Cl
4.A61M1/03。" external lung auxiliary device " by inventions such as Tohrn Morioka is mainly used in the treatment acute respiratory failure.United States Patent (USP), the patent No.: 4,755,168.Int.Cl
4.A61M1/03。Be mainly used in the drainage wash of organ by " the medical drainage pump and the purging method " of inventions such as Pat Romanelli.United States Patent (USP), the patent No.: 4.838,865.Int.Cl
4，A61M1/03。" liquid monitoring system " by inventions such as Hans P.Flank can be used for hemodialysis, hemofiltration, but design is too complicated, and volume is big.United States Patent (USP), the patent No.: 4,769,001 Int.Cl
4, A61M1/03." standard combination pump liquid drainage system apparatus and method " by Paul R.Pince invention are the separation when being used for plasmapheresis.This system applies two pumps, can not carry out hemodialysis, feasible separating plasma and filtration, its shortcoming is that volume is big and heavy.
Purpose of the present invention, a kind of serial automatic hemo-dialyser that designs at above deficiency exactly.Automatic hemo-dialyser has been simplified conventional artificial kidney machine's dialysis solution feed system widely, does not rely on the water source, can freely move the patient and rescue at one's side, not limited by the place.Automatic hemo-dialyser is simplified to complicated conventional artificial kidney machine just like a medical little treatment center, basic point of the present invention that Here it is, the purpose of this series that Here it is invention.So, the patient that can make numerous needs obtain blood purification treatment can both obtain treatment, thereby improves the situation that the following medical institutions in present numerous unit, especially county and county hang back in the face of the conventional artificial kidney machine of expensive import.The automatic hemo-dialyser series technical project can make the hemodialysis carried out, hemodiafiltration etc. realize automatization or semi-automation, improves individual medical personnel's work efficiency.The present invention is fit to hospitals at different levels, the big-and-middle-sized hospital that especially carries out specific treatment, and county, city, district, township level hospital, factories and miness hospital, Army ambulance corps, individual specialist clinics etc. have large-scale application prospect.
The present invention is achieved in that a kind of medical automatic hemo-dialyser, and it is by first roller pump (1), ductus arteriosus (2), arterial end blood sampling hole (3), A end transfusion short tube (4), append calparine pipe (5), heparin syringe (6), dialyser or filter (7), venous duct (8), bubble trap (9), exhaustor (10), vein pressure pipe (11), venous pressure table (12), V end transfusion short tube (13), vein end blood sampling hole (14), second roller pump (15), dialysis liquid pool (16), first dialyzate bag (16-1), second dialyzate bag (16-2), the first dialysis solution circulation pipe (17), the second dialysis solution circulation pipe (18), electronic measuring device (19), object wearing device (20), go-cart (21), hemo system display screen (22), hemo system display screen button (23), the automatic hemo-dialyser that infusion support (24) constitutes, as Fig. 1, Fig. 2, shown in Figure 3, it is characterized in that: in the designed overall structure, thick section (1-1) by the convex roller of first roller pump (1) rolls ductus arteriosus (2), the process auxiliary drive blood circulation, the thin segment (1-2) of first roller pump (1) convex roller, roll the first dialysis solution circulation pipe (17) and drive the dialysis solution circulation, the thick section of the roller of convex roller pump (1-1) diameter is 20mm, and length is 18mm; The thin segment of roller (1-2) diameter is 15mm, and length is 23mm, and other adnexa is determined according to the size of convex roller pump convex roller, as Fig. 4, shown in Figure 5; Fig. 2, first roller pump (1) and second roller pump (15) shown in Figure 3 are non-convex roller pump, and the loop direction of dialysis solution is decided according to the position that roller rotation side is high and dialysis solution circulation pipe (17,18) is put of second roller pump (15).
