Description

A blood transfusion box container with temperature and speed control

technical field

The utility model relates to the technical field of medical equipment, in particular to a temperature-controlled and speed-controlled blood transfusion box container.

Background technique

In hospital blood banks, some blood products are stored at temperatures below 4°C. Therefore, even if the blood products in the blood bag can reach a room temperature of 15°C after being taken out of the refrigerator, it is still far below the normal body temperature of 37°C. In first aid and surgical massive blood transfusion, if a large amount of these low-temperature liquids are injected into the human body, the body temperature of the patient will drop, thereby changing the normal temperature of the enzyme reaction in the human body, seriously affecting the enzyme-catalyzed biochemical reaction of the whole body, and threatening the life function. At the same time, the patient shivered due to hypothermia and metabolized rapidly, threatening the lives of critically ill patients. Therefore, large infusions of unheated blood products would cause great danger to rescue work.

In addition, when unheated blood products enter the blood vessels, the smooth muscles of the blood vessels will shrink instinctively, and the blood vessels will become thinner, thereby increasing the resistance, hindering the smooth infusion, and increasing the pain of the patient.

Therefore, for the above-mentioned blood products, in the traditional infusion method, most of them are to apply hot towels to the proximal end of the patient's infusion venipuncture point, so as to increase the temperature of the blood in the infusion tube, thereby reducing the impact of low temperature on the human body. However, this extensive practice has great disadvantages. First of all, it usually takes 1 to 2 hours for a bag of blood to be transfused, and the hot towel cools down very quickly, keeping it warm for up to ten minutes. In the rest of the time, it is difficult to ensure the continuous temperature of the infusion solution, so the adverse reaction of condensation in the blood will inevitably occur. Secondly, the hot towel at 50°C directly heats the blood vessels under the skin, and if it is higher than 38°C, there is a risk of red blood cell destruction, which will cause hemolysis. Therefore, this infusion method is cumbersome to operate, has low efficiency, and the temperature and speed are uncontrollable, which also has certain dangers.

Therefore, it is necessary to provide a technical solution that can increase the temperature during blood transfusion and improve the convenience of transfusion.
