在医学临床方面、特别是心脏外科,迫切需要一种全身降温设备,以保证体外循环心内直视手术的施行。为了解决医疗工作的这一急需,我厂在上海新华医院和青海医学院等单位的协助下,开始了这个项目的研制。根据参加协作各单位商定的方案,采用了以温差电现象为基础的半导体致冷技术。在试验试制的过程中,首先是用 P 型和 N 型元件制成电堆,置于全身大血管集中的部位,试行降温,发现冷量不足,达不到所需的低温。在接受了这个失败的经验后,修改了设计方
In clinical medicine, especially cardiac surgery, an urgent need for a systemic cooling equipment to ensure the implementation of cardiopulmonary bypass surgery. In order to solve this urgent need of medical work, I plant in Shanghai Xinhua Hospital and Qinghai Medical College and other units with the help of the project started. According to the scheme agreed by participating units, the semiconductor cooling technology based on the thermoelectric power was used. In the trial trial process, the first is made of P-type and N-type components stack, placed in the body parts of the large blood vessels, trial cooling, lack of cold found, reach the desired low temperature. After accepting this unsuccessful experience, the designer was modified
