Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature blood transfusion, in particular to a constant temperature blood transfusion device. Background Art

[0002] Blood transfusion refers to a treatment method in which blood is infused into a patient through a vein. It is widely used clinically. After blood is collected, in order to preserve the blood for transfusion for a certain period of time, the blood needs to be preserved. Blood preservation generally refers to the storage of whole blood and frozen blood (red blood cell products). The collected whole blood needs to be stored at a temperature of 4℃±2℃, after using an anticoagulant, and placed in a blood storage refrigerator for storage. The storage time is 21-35 days. The process of freezing blood is as follows: the collected whole blood is separated into red blood cells and plasma, and a cryoprotectant (glycerol) is added to the red blood cells. Under sterile conditions, the blood is transferred from an ordinary blood collection bag to a special plastic bag and stored in a refrigerator at minus 80 degrees Celsius.

[0003] Blood needs to be heated before use. Refrigerated or room temperature blood needs to be heated to a suitable temperature before use. However, during the infusion process, the heat of the blood will be dissipated, causing the temperature of the blood injected into the body to be lower, leading to a lower body temperature, causing hypothermia and its related complications.
