The adjustable spraying device comprises a
medicine storage chamber, a cover body and an extraction
pipe, the cover body is in threaded connection with the upper portion of the
medicine storage chamber, the extraction
pipe is connected to the lower portion of the cover body, the extraction
pipe is located in the
medicine storage chamber and used for extracting an
anesthetic, a connector is fixed to the upper portion of the cover body, and the connector is connected with the upper portion of the cover body. The interior of the connector is communicated with the extraction pipe, and the
anesthetic in the extraction pipe is guided. According to the adjustable and controllable spraying device for clinical
local anesthesia of the
anesthesiology department, different spraying ranges can be adjusted through the arrangement of the multiple spraying heads on the movable cover, the spraying head needing to be used can be selected by rotating the movable cover, and a second telescopic hose at the inner end of the adjusted spraying head can be automatically attached to a connector; in addition, by matching with mutual attraction of a first magnetic block and a second magnetic block, positioning of rotation of the movable cover can be achieved, the adjustability and subsequent use convenience of the device are improved, and different
local anesthesia requirements can be met.
