They occupy a very important position in the field of modern medicine. Ventilators are a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives.
[0003] When a patient wears a ventilator, condensed water will condense in the trachea of the ventilator. The condensed water will be collected and poured out through a liquid tank, but the condensed water will accumulate more and more. When medical staff are busy, they cannot pour out the condensed water in time. If the condensed water is not poured out in time, the bacterial concentration will increase, and the backflow of condensed water will cause VAP. Excessive condensed water will affect the patient's ventilation and contaminate the pipeline. Therefore, there is an urgent need for a ventilator pipeline condensate monitoring and drainage device to overcome the above defects. Utility Model Content

[0022] More specifically, by setting up a blocking and draining assembly 2, it is convenient to discharge condensed water. When in use, condensed water is introduced into the inner cavity of the storage tank 11 through the guide joint 13. At the same time, when the condensed water increases, the buoyancy causes the buoyancy float 36 to drive the connecting rod 34 and the slider 37 to move upward. When it moves to the specified position, the connecting rod 34 contacts the pressure switch 32, thereby generating an electrical signal to be transmitted to the controller 12.

[0029] Working principle:
[0030] Step 1: During use, condensed water is introduced into the inner cavity of the storage tank 11 through the diversion joint 13. At the same time, as the condensed water increases, the buoyancy causes the buoyancy float 36 to drive the connecting rod 34 and the slider 37 to move upward. When they move to the specified position, the connecting rod 34 contacts the pressure switch 32, thereby generating an electrical signal to be transmitted to the controller 12. Under the action of the controller 12, the motor 25 drives the blocking block 21 to rotate. After rotating to the specified position, the blockage of the top of the drain pipe 26 is released.
[0031] Step 2: The condensed water is discharged through the drain pipe 26, and then under the control of the controller 12, the motor 25 drives the blocking block 21 to reset, thereby blocking the drain pipe 26. When the water level monitoring component 3 fails, the water level is monitored under the action of the liquid level sensor 4, which has the advantages of good monitoring effect and automatic drainage function.
