Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a condensate recovery and drainage device for a closed ventilator capable of pressure warning. Background Art

[0002] Patients with severe pneumonia are in critical condition and need oral intubation and ventilator-assisted ventilation when combined with respiratory failure. When the ventilator is in use, sterile water for injection will form condensed water during the humidification process of the airway, and the water vapor exhaled by the patient will adhere to the pipeline. At this time, it is necessary to collect it through a condensate recovery device to prevent the condensed water carrying bacteria from flowing back into the airway, so as to facilitate the subsequent centralized treatment of the condensed water.

[0003] However, when using the existing ventilator condensate recovery and drainage device, the nursing staff is required to pay attention to the water level in the collection tank at all times. When the water level reaches a certain level, the nursing staff must pour out the condensate in time to prevent the condensate from flowing back. However, this will increase the workload of medical staff, and the structure of the existing ventilator condensate recovery and drainage device for containing condensate is imperfect. When the nursing staff is busy at work, they may not have time to pour out the condensate in the collection tank in time, which will easily lead to the condensate flowing back. In addition, too much condensate in the collection tank may cause condensate to splash during the pouring process, increasing the risk of occupational exposure. Utility Model Content

When the tank body is full, the lifting member can be pushed to push the condensed water in the tank body into the connecting pipe. In this way, there is no need to remove the tank body from the cover body to pour out the condensed water. This can avoid splashing of condensed water when removing the tank body, thereby preventing infection to medical staff. BRIEF DESCRIPTION OF THE DRAWINGS
