Sterile powder spraying device used for nursing wounds and closing wound surfaces

The invention relates to the technical field of medical apparatus and instruments, and in particular relates to a sterile powder spraying device used for nursing wounds and closing wound surfaces. Thesterile powder spraying device comprises a powder fluidizing device, a drive air source, an air filtering device and a spray head, wherein the powder fluidizing device can be directly inserted into apower container, sterile air is provided for the powder fluidizing device through the drive air source, after being fluidized, liquid formed by the powder is sprayed out through the spray head and isuniformly sprayed to the wound surfaces. The device can continuously, stably and uniformly spray sterile medicine powder to the wound surfaces of a patient in a controllable manner, a motor does notneed to be placed in a bottle, thus the pollution caused to the medicine powder can be avoided, the complete sterile effect is realized, and thus the safety is high. 本发明涉及医疗器械技术领域，尤其是种用于伤口护理、创面封闭的便携式无菌粉末喷涂装置，其包括粉末流化装置、驱动气源、气体过滤装
