Abstract

The invention discloses a filter used for the air pressure return pipeline of a non-invasive ventilation synchronous ventilator. One side of the filter body is provided with an inlet pipe interface, and the other side of the filter body is provided with an outlet pipe interface. There is an air filter grille between the filter bodies, a first filter cylinder is provided on the side of the filter body, a first filter element is provided in the first filter cylinder, and a second filter cylinder is provided on the other side of the filter body. A second filter element is arranged in the filter cylinder, and a reversing shaft is arranged on the filter body, and a rotating handle is arranged on the reversing shaft, and the first filter element or the second filter element can be selected to be connected to the air pressure return pipeline by turning the reversing shaft. The filter of the present invention for the air pressure return pipeline of a non-invasive ventilation synchronous ventilator is provided with two filter cylinders on the body, and one of the filter cylinders can be selected to be connected to the air pressure return pipeline by turning the reversing shaft, even if it is The used ventilator can also replace the filter element for the filter, which is fast and convenient.

Description

technical field [0001] The invention relates to the medical field, more precisely, it is a filter for the air pressure return circuit of a non-invasive ventilation synchronous ventilator. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. Ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients. The filter used in the air pressure return line of the non-invasive ventilation synchronous ventilator is an important part of the air pressure return line, but the filter currently commonly used has the disadvantage of being diffi...
