Blood transfusion sets are used in medical devices for infusing blood. It mainly consists of blood transfusion bag, blood transfusion pipeline, blood transfusion needle, etc. Blood transfusion sets are used for infusing bagged blood products such as erythrocytes, platelets, cryoprecipitates, and bottled blood products such as albumin, gamma globulin, factor VIII, etc. Blood transfusion tubes generally use soft transparent plastic tubing for transporting blood. The joints of all parts of the blood transfusion device usually have a leakage-proof function, so that no external pollution is caused in the process of transfusion. Blood transfusion needles are used to puncture a patient's blood vessel to deliver blood into the patient. The blood transfusion apparatus works on the principle that blood is driven by gravity or pressure difference to flow from a blood transfusion bag through a blood transfusion pipeline into the vascular system of a patient.
The existing transfusion device has thick and long needle head, is easy to puncture a transfusion bag to cause blood leakage, and the blood stuck on the transfusion bag at the end of transfusion can not be completely injected into a patient, thereby wasting precious blood resources, the existing transfusion device has longer tube above the bifurcation, when blood is transfused, the blood inside the side tube of the transfusion bag can not be completely transfused into a patient, or when the transfusion device is used for bottled blood products such as albumin or gamma globulin, the liquid is very little, the liquid can easily reach the lower part of the filter screen during replacement, and if the liquid is extruded or the foam is too much, the last foam is transmitted to be adhered to the tube wall, so that waste is caused. When blood transfusion is finished, blood leaks out during blood product treatment, blood pollution is easy to cause in the process of destroying blood transfusion apparatuses, and blood is easy to cause on scissors or is caught on hands of nurses.
