Description

Technical Field

[0001] The invention relates to the technical field of liquid biological culture and separation devices, in particular to a blood warming device. Background Art

[0002] Blood cancer patients need blood transfusions in certain cases. For example, severe anemia or bleeding may occur during hematopoietic stem cell transplantation, chemotherapy or radiotherapy. At this time, blood transfusion can help improve oxygen carrying capacity, replenish lost blood components, and support the treatment process. When giving blood transfusions to patients, the blood usually needs to be warmed. Blood warming equipment in the prior art is usually divided into two forms, one is to heat the blood bag, and the other is to heat the blood transfusion tube. Both forms use heat conduction heating. The former, due to its large volume and low heat conduction efficiency, is prone to uneven heating. The latter, due to its small volume, can be evenly heated.

[0026] The medium heating mechanism 2 comprises a cylindrical body 21 with a hollow interior, a heating mechanism and a water pump 26 are arranged in the cylindrical body 21, a liquid outlet pipe 22 is arranged at the bottom of the cylindrical body 21, and the liquid outlet of the water pump 26 is connected to the liquid outlet pipe 22; one of the semi-cylinders 11 is fixedly arranged at the top of the cylindrical body 21; the cylindrical body 21 is connected to the semi-cylinder 11 fixedly arranged on the cylindrical body 21 through the through hole 18; the top of the cylindrical body 21 is provided with a guide groove 23 opposite to the semi-cylindrical groove 12, and the guide groove 23 is used to guide the blood transfusion tube;
