Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical blood transfusion technology, and more specifically, to a heatable and pressurized blood transfusion device for a blood transfusion department. Background Art
[0002] Blood transfusion therapy is an important part of clinical treatment in hematology and one of the main means of saving lives and preventing and treating diseases. Under normal conditions, blood bag heating is mainly to improve the comfort of patients, so the temperature does not need to be as high as in an emergency. The warm water temperature is usually controlled at 32-35°C. This temperature can prevent the blood components from being destroyed by high temperature, and at the same time make the patient feel more comfortable during the transfusion process. At the same time, the existing blood transfusion devices heat the blood at the outlet of the blood bag. If the ambient temperature is low, the temperature of the blood is already low when it reaches the patient, and the actual effect of the blood heating device is greatly affected. When there is a temperature difference in the blood bag, the red blood cells may be stimulated by uneven cold and heat. If the temperature difference is large, such as the local temperature is too high, the cell membrane fluidity of the red blood cells will change, the stability of the cell membrane will decrease, and it is easy to cause the red blood cells to rupture, that is, hemolysis. Once the red blood cells rupture, hemoglobin will be released. On the one hand, the function of hemoglobin is lost and it cannot carry oxygen and carbon dioxide normally; on the other hand, after a large amount of hemoglobin enters the plasma, it may block the renal tubules and cause serious consequences such as acute renal failure.
[0003] In existing blood transfusion therapy, blood is mostly heated through a single pretreatment or temperature increase during transfusion. This type of heating method has a single function and cannot be adapted to routine and emergency transfusion operations. In view of this, we propose a blood transfusion device that can be heated and pressurized for use in the blood transfusion department. Summary of the invention
