Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to an extracorporeal circulation pipeline of an improved novel blood purification device.
Background
End stage renal disease is the final stage of disease progression in chronic kidney disease, a progressive, irreversible impairment of kidney structure or function caused by a variety of causes, and has become a global public health problem that severely jeopardizes human health. Renal replacement therapy is the only effective treatment for end stage renal patients to sustain life and mainly includes hemodialysis, peritoneal dialysis and renal transplantation. Of these, hemodialysis is most commonly used. Hemodialysis is to take the blood of a patient out of the body through a purification device according to the semipermeable membrane permeation principle, and perform substance exchange by utilizing functions of dispersion, ultrafiltration and the like, so as to achieve the purpose of correcting the balance of water electrolyte and acid and alkali. During the treatment, blood is usually circulated in the dialyzer and the extracorporeal circulation blood circuit at a pump speed of 200-300 ml/min, if the blood circuit pipeline is poorly fixed, the blood circuit pipeline can be separated from the joint of the central venous catheter or the fistula puncture needle, so that a large amount of blood flows out of the pipeline, and the life of a patient can be endangered in severe cases, so that the fixation of the extracorporeal circulation blood circuit pipeline is very important; according to guidelines, the patient's dialysis treatment time is set to be 5.0-5.5 h/time for 2 times per week and 4.0-4.5 h/time for 3 times per week according to the dialysis treatment frequency. Therefore, in the long-time dialysis treatment, medical staff needs to fix the extracorporeal circulation blood tube properly so as to ensure the dialysis safety of patients. At present, the pipeline is usually fixed by two modes of vascular clamps or adhesive tapes in clinic. In the practical process, the sticking of the adhesive tape can be unstable due to the problem of adhesive tape viscosity reduction, and part of critical patients can pull the blood vessel tube due to agitation caused by diseases, so that the tube is shifted and even falls off, therefore, the tube clamp is mostly used for fixing the tube on the bed sheet in clinic. However, the vascular forceps have certain dead weight, so that the potential safety hazard is also possibly caused, and meanwhile, the used vascular forceps need to be conventionally sterilized to prevent cross infection, so that the complicated work task of clinical medical staff is greatly increased; hypocalcemia is a common chronic complication of maintenance hemodialysis patients, and during dialysis treatment, doctors prescribe intravenous pumping of calcium gluconate in order to supplement the calcium ions removed in hemodialysis and maintain the balance of internal and external potentials of skeletal muscle cells and cardiac muscle cells. Because the medicine has small molecular weight, the medicine needs to be slowly and continuously administered from the intravenous kettle end in order to ensure the stable exertion of medicine effect without purification. Meanwhile, during dialysis treatment, patients may cause a decrease in plasma osmotic pressure due to rapid clearance of blood solutes, an increase in osmotic pressure difference between blood and brain tissue fluid, and water transfer to brain tissue, thereby causing an imbalance syndrome. If the patient is accompanied by muscle cramps, the complications are treated by simultaneous infusion of 4% sodium bicarbonate, 10% sodium chloride or 50% glucose solution. In the present stage, only one drug injection connector is arranged on the extracorporeal circulation blood circuit used clinically, and the extracorporeal circulation blood circuit is often occupied by accessing physiological saline, so that when the condition that the additional drug is needed to be pumped occurs, a corresponding drug injection channel is lacked to meet the requirement of actual work, and therefore, an improved extracorporeal circulation pipeline of a novel blood purification device is provided.
