Abstract
The utility model discloses a disposable extracorporeal circulation arterial side blood loop structure matched with a kidney machine. The loop structure is characterized in that connecting threads are added at a connecting end of a bottle-inserting needle, so that the bottle-inserting needle can be directly connected with a shunting connector. The loop structure has the advantages of simple structure and smaller length of a straight pipe of the shunting connector; and during the disassembly of the bottle-inserting needle, a fixing nut on the shunting connector can be screwed to produce a backward thrust with a rear lug boss of the shunting connector, so that an insertion end of the shunting connector can be released for automatic disassembly of the bottle-inserting needle, thereby dispensing with forceful pulling for disassembly and achieving easy disassembling operation..
Description
Technical field
This utility model belongs to technical field of medical instruments, particularly relates to disposable use extracorporeal circulation arterial side blood loop structure.
Background technology
This utility model relates to a kind of and the supporting use of hemodialyzer, is applicable to the uremia that acute and chronic renal failure causes and need carries out the extracorporeally circulating blood pipeline that the artificial kidney hemodialysis patients carries out the extracorporeal blood dialysis treatment.At present, known disposable use extracorporeal circulation blood circuit is divided into arterial side, the venous side two independent parts constitutes, critical piece has plug-in type cone joint, negative pressure monitor, irrigator (or transfusion device), pump line, anticoagulant pipeline, cartridge filter, drainage screen, dialyser joint, and some medicines inject with branched pipe and the flexible pipe that is connected with upper-part.This product is and the supporting use of hemodialyzer, is applicable to the uremia that acute and chronic renal failure causes and need carries out the extracorporeally circulating blood pipeline that the artificial kidney hemodialysis patients carries out the extracorporeal blood dialysis treatment.
Fig. 2 is needle for inserting bottle and an adapter assembly existing structure sketch map in the disposable use extracorporeal circulation of the prior art arterial side blood loop structure.Needle for inserting bottle 23 in the prior art arterial side blood circuit structure connects flexible pipe 24, flexible pipe 24 is connected with adapter 25, it is fixing with hold-down nut 26 that adapter 25 other ends are provided with screw thread, hold-down nut 26 connection hard tubes 27 ', hard tube 27 ' with dividing pipeline connector 27 is integrally formed, divides the length of the straight-tube portion of pipeline connector 27 to be set to length greater than hold-down nut 26.Disposable use extracorporeal circulation arterial side blood loop structure is the passage that connects extracorporal dialysis equipment such as human body and hemodialyzer, hemodiafiltration device, is disposable macromolecule pipeline.Cardinal principle is: dialysis system flushing time-division pipeline connector is connected with needle for inserting bottle, carrying out hemodialysis time-division pipeline connector is connected with disposable use diacan subassembly product and hold-down nut is tightened, after puncture needle inserts the human body artery blood vessel, then blood is introduced the arterial side blood circuit, roller pump on the dialyser is by the pump line of roller extruding arterial side blood circuit, for blood provides power external flowing, the anticoagulant branch line is by introducing heparin, make that blood is unlikely in the loop solidifies, other branch line can be adjusted pipeline with the medicine flow in pipes of dialyser with horizontal plane respectively and be connected, when each branch line uses little nothing wheel Shui is only opened, the time spent does not close little nothing wheel Shui and only gets final product, the dialyser joint makes blood circuit be connected with dialyser, blood is introduced in the dialyser, blood carries out mass exchange with dialysis solution in the doughnut of being made by semipermeable membrane there, and dialysis solution is driven constantly to flow by dialysis machine and upgrades, and the main process of dialysis is here finished.But, irrigator (or transfusion device) needle for inserting bottle modular construction is complicated in the existing disposable use extracorporeal circulation arterial side blood loop structure, also inconvenient during clinical disassembling section, as when dismantling needle for inserting bottle or diacan, unscrew behind the hold-down nut on the branch pipeline connector owing to divide the front end conehead of pipeline connector also to be inserted in the taper hole of needle for inserting bottle or artery and vein puncture needle connector, needing operator firmly to tear open pulls out just and can dismantle, particularly this is firmly torn open and pulls out the operating physical force of dismantling, dismounting during diacan such as misoperation can conduct on the syringe needle that inserts in the patient vessel, make the patient suffering, needle point can puncture blood vessel when serious.
Summary of the invention
The purpose of this utility model be for overcome needle for inserting bottle in the existing disposable use extracorporeal circulation arterial side blood loop structure and along separate routes complicated, the clinical manipulation of adapter assembly structure connect the inconvenient problem of dismounting, and design a kind of needle for inserting bottle and along separate routes adapter assembly simple for structure, easily connect the disposable use extracorporeal circulation arterial side blood loop structure of disassembling section, reduce the misery that connects at arterial puncture needle, reduces the patient when tearing open.The technical scheme that its technical problem that solves this utility model adopts is:
