[0002] Thyroid surgery is one of the common methods for treating thyroid diseases. Thyroid tissue and lymphatic tissue that need to be treated during surgery often produce fluid accumulation. In order to avoid postoperative complications, drainage operations are required to drain the accumulated fluid and keep the surgical wound dry and clean.
[0003] Traditional thyroid surgical negative pressure drainage devices have the following defects: first, the air sucked out by the vacuum pump in the traditional device comes into contact with the drained liquid, and direct discharge poses a risk of cross-infection; second, the pressure inside the negative pressure box in the traditional device cannot be accurately controlled. Too little negative pressure cannot completely suck out the accumulated fluid, and too much negative pressure will cause discomfort to the patient. Utility Model Content

[0011] Compared with the prior art, the utility model has the following advantages:
[0012] 1. Prevent cross infection: An ultraviolet disinfection lamp is fixed on the top surface of the negative pressure box to disinfect the drainage fluid and improve the overall hygiene level. The exhaust gas discharged by the micro vacuum pump will be cleaned by the disinfectant in the disinfection box before being discharged, thus avoiding the risk of cross infection.
[0013] 2. Accurately control negative pressure: The negative pressure can be precisely controlled through the pressure control mechanism to ensure that the size of the negative pressure is suitable for the patient's needs, avoiding the problem that the negative pressure is too small to completely suck out the accumulated fluid or the negative pressure is too large to cause discomfort to the patient.
