The invention discloses a ventilator connector and a ventilator, wherein the ventilator connector is used for connecting a ventilator body and an external catheter. The ventilator connector comprisesan external tube connector, an insert and a cannula. The external tube connector has a first end and a second end; the first end of the external connector is used for connecting the ventilator body. The insert is used for setting detection components and is arranged at the second end of the external tube connector. The cannula is used for connecting the external catheter and is connected to the second end of the external tube connector in order to limit the insert. The ventilator connector of the embodiment has the advantages that assembly and fixation can be performed after the external tubeconnector, the insert and the cannula are manufactured separately, the parts are easy to manufacture, post-connection integrity is good, the appearance is complete, and air-oxygen mixed gas can be imported smoothly and can be heated to a suitable temperature; the detection components are centrally arranged on the insert, manufacturing is convenient, and space is saved.
