Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to an extracorporeal circulation pipeline.
Background
Hemodialysis is a main alternative treatment mode for patients with end-stage renal disease, blood of the patients is pulled out of the body by a power device, enters a dialyzer through an extracorporeal circulation arterial blood circuit, exchanges substances and removes redundant water in the body of the patients, and is then returned to the body of the patients through an extracorporeal circulation venous blood circuit so as to achieve the purpose of treatment. In the hemodiafiltration mode of treatment, replacement fluid replenishment is required to increase the convection current to aid in the removal of more medium and large molecular weight toxins. During hemodialysis treatment, a replacement fluid pipeline is required to be connected to an arterial kettle or a venous kettle of an extracorporeal blood circuit, and sterile and pyrogen-free replacement fluid enters a human body to supplement water lost due to ultrafiltration. In the dialysis process, the inlet pot and the venous pot of the dialyzer are the parts which are most easy to cause coagulation blockage, and corresponding emergency measures (generally, the machine is put down) are needed once the coagulation blockage occurs, so that the life safety of a patient is ensured.
Currently, a set of extracorporeal circulation blood circuit and a set of replacement liquid pipeline are needed for completing hemodialysis filtration treatment, the extracorporeal circulation system is built in an assembled mode, in addition, the treatment modes (such as front replacement and back replacement) are replaced in the middle of the hemodialysis filtration treatment, and the replacement liquid pipeline needs to be disconnected from a connecting kettle and is connected to the connecting part of the corresponding treatment modes again. The substitution liquid discharged from the inside of the machine is generally directly injected into the extracorporeal circulation blood, and no further filtration treatment is performed on the discharged substitution liquid. Because the blood circuit and the replacement liquid pipeline are respectively packaged in different packaging bags, the production cost is increased, the labor intensity of medical staff is also increased, and in addition, the wrong packaging operation exists in the process of assembling the blood circuit and the replacement liquid pipeline together, so that medical accidents are caused; secondly, the outlet end of the clinically used replacement liquid pipe is designed to be a single outlet, the operation of changing the treatment mode in the middle of hemofiltration treatment is inconvenient, the risk of liquid pollution exists, and the replacement liquid coming out of the machine can not be further filtered.
