在新型冠状病毒肺炎疫情期间，由于需要采集大量核酸样本，工作人员压力较大。为此，中日友好医院的医务人员研制了一种移动式正压洁净舱，并申请了国家实用新型专利（申请号：202021173605.8）。该设备主要由舱体、装有橡胶手套的操作孔、设置两扇电动门的交互通道、环境调节组件及空调等设施构成。使用时，医务工作人员位于舱体内部，双手由两个操作孔伸出，为等待检测人员进行核酸采样，然后将样本放置于舱外桌面等待送检。该洁净舱可用于医院、社区等地定点采集核酸样本，在达到高效采集样本这一目标的同时，通过有效阻隔医务工作人员与传染源的接触，进而降低在采样过程中被感染的风险。“,”During the epidemic of coronavirus disease 2019, due to the need to collect a large number of nucleic acid samples, the staff are under great pressure. For this reason, the medical staff of China-Japan Friendship Hospital developed a mobile positive pressure clean chamber and applied for a national utility model patent (application number: 202021173605.8). The equipment is composed of a cabin body, an operation hole equipped with rubber gloves, an interactive channel with two electric doors, an environmental control unitandanair-conditioner. When in use, the medical staff are located inside the cabin, and their hands are protruded by two operating holes to calculate and sample for the tested personnel. Then the samples are placed on the table outside the cabin waiting for inspection. The clean chamber can be used in hospitals, communities and other places, while achieving the goal of efficient sampling, and the risk of infection in the process is reduced by effectively blocking the contact between medical staff and the source of infection.
