Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a controllable spray device for clinical local anesthesia. Background Art

[0002] In clinical medical practice, local anesthesia is one of the commonly used anesthesia methods in surgical and diagnostic procedures. By injecting or spraying anesthetic drugs into specific parts of the patient, the sensory nerves in that part are blocked, thereby achieving the purpose of reducing pain and facilitating surgical operations. With the continuous progress of medical technology, the application of spray devices in local anesthesia has gradually received attention. The spray device converts anesthetic drugs into fine droplets through atomization technology and evenly sprays them on the anesthetic part of the patient, with the advantages of simple operation, uniform distribution of anesthetic drugs, and rapid anesthetic effect.

[0003] However, most of the existing local anesthesia spray devices have problems with insufficient regulation performance and cannot meet the precise control requirements for anesthetic depth and drug dosage in clinical practice. Summary of the Invention

[0007] Further, an electromagnetic valve is provided between the nozzle and the anesthetic cylinder; a switch is provided on the limiting plate, and by sliding the piston head into contact with the limiting plate, the switch is triggered to control the liquid extraction pump to stop working.

[0008] Further, a foot controller is connected to the liquid extraction pump through a guide to control the operation of the liquid extraction pump.

[0009] Further, the syringe driver includes a holding seat and a pushing plate. The pushing plate is slidably mounted on the holding seat, and a clamping plate is rotatably arranged on the holding seat. The other end of the clamping plate is connected to the holding seat by a bolt. The anesthetic cylinder is placed on the holding seat, and the anesthetic cylinder is fixed by rotating the clamping plate. The pushing plate abuts against the rear end of the push rod.

[0010] Further, a lead screw is rotatably arranged on the holding seat. The pushing plate is threadedly sleeved on the lead screw, and a motor is fixedly arranged in the holding seat.
