During the Pidu epidemic in Chengdu, I went to Sichuan Friendship Hospital for nucleic acid testing, which was very impressive at that time, because I had done nucleic acid testing in other hospitals before, all in temporary houses. But in Sichuan Friendship Hospital, there are not only temporary tents and houses, but also nucleic acid sampling cabins that have never been seen before. The nurse stood in that square transparent room, sampling through sampling gloves, which was a bit high-tech. It was still snowing outside on the day I went, but the clothes worn by the nurses in the sampling cabin were not very thick, and there seemed to be air conditioning. This kind of equipment is really good, which can make the medical staff less hard. Oh, by the way, that sampling cabin seems to be Haier's, too. I remember that at the beginning of the epidemic, Sichuan Friendship Hospital was designated by the government as the designated hospital for suspected cases in COVID-19, and later it was designated as the nucleic acid detection point when the epidemic was repeated. I feel that no hospital undertakes such a critical moment.
