用于血液保温输注的血袋辫加热套的设计

Design of Tube Warmer of Blood Bag for Blood Transfusion

目的研制可以使得血袋辫升温的保温套,使血液输注前的温度得以提高,以保证输血安全。方法设计可闭合的长圆柱体升温套,血辫置入后流经该套的低温血得以升温,采用基于高性能的温度传感器控制温度,采用电子加热线路加热。结果经反复研讨该血袋辫加热保温套安全可靠,达到设计的要求。结论该保温套可以方便的用于血液输注前的升温。

Objective In order to design a tube warmer of the blood bag, which could rise the blood temperature before it being transfused, thus to ensure the safety of blood transfusions. Methods Design a dismountable long cylinder tube warmer. When put tube into the warmer, the cold blood that flow through the tube will be warmed up. The whole device based on the high-performance temperature sensor and electronic circuits are used as the warming materials. Results The tube warmer is safe and reliable, and reaches the demand of clinical design. Conclusion The tube warmer should be used to rise the temperature of blood before it being transfused conveniently.
