Blood bag with saline balloon and used for blood transfusion of hematological patients

Abstract

The invention belongs to the technical field of medical apparatuses and discloses a blood bag with a saline balloon and used for blood transfusion of hematological patients. The blood bag comprises abag body, the inner wall of the bag body is provided with a first partition pad and a second partition pad, the bag body is internally provided with a first saline cavity, a second saline cavity and ablood cavity, and the upper surface of the first partition pad is provided with a second seal plate. The blood bag with the saline balloon and used for blood transfusion of the hematological patientshas advantages that by cooperation of the first saline cavity, the second saline cavity, the blood cavity, the first partition pad, the second partition pad, the first seal plate, a second seal plateand a check valve, after blood transfusion is finished, the check valve is turned on, then blood in the blood cavity and a tube is flushed by saline in the second saline cavity, blood infusion and cleaning processes of each blood bag are guaranteed against plugging and unplugging of a blood transfusion apparatus while convenience in flushing before and after blood transfusion is achieved, and accordingly workload of operating personnel can be relieved while probability of air mixed in blood is lowered, and smoothness and stability in a blood transfusion process are guaranteed to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, in particular to a saline bag blood bag for blood transfusion of blood patients. Background technique [0002] At present, in clinical work, according to blood transfusion requirements, normal saline is used to flush the pipeline before blood transfusion to prevent blood transfusion reactions, and normal saline is used to flush the pipeline after blood transfusion to avoid blood waste. Coagulation reaction occurs, and now the use of normal saline in the whole blood transfusion process needs to pull out the blood bag at one end of the blood transfusion set many times, resulting in a cumbersome operation process. At the same time, air may be mixed in the blood transfusion set, which brings great inconvenience to the blood transfusion process. Contents of the invention [0003] (1) Solved technical problems [0004] In order to overcome the above-mentioned defects of the prior art, the...
