Problems solved by technology
The paired processing method generally has a complex structure, and the processing is difficult and the production cost is also high.
The method with a certain amount of flexible adjustment is mainly to use the rigid valve and the sealing ring for docking. In this method, the deformation of the sealing ring is small, and there is generally a certain gap for the smooth insertion of moving parts, so that Air leakage will occur, especially when the movable parts swing up and down, the probability of air leakage will increase greatly, and the practicability will be poor.

The invention discloses a docking device for an exhalation valve and a ventilator having the same. The docking device comprises: an annular mounting seat; a plug, which is fitted in the mounting seat and is pluggable relative to the mounting seat, the plug is provided with a cavity and a gas channel, one side of the cavity is open, and the gas channel communicates with the cavity; The air nozzle fixing plate is arranged on one side of the mounting seat, and the air nozzle fixing plate is provided with a plurality of air nozzle insertion holes; and the flexible air nozzle, the flexible air nozzle is tightly fitted in the air nozzle insertion hole and the flexible air nozzle is communicated with the gas channel. According to the docking device for the exhalation valve according to the embodiment of the present invention, by arranging the flexible air nozzle and tightly fitting the flexible air nozzle and the air nozzle insertion hole, the sealing performance of the two is improved. The sealing of the gas in the docking device has an impact, which not only reduces the processing and assembling accuracy of the docking device, but also greatly improves the production qualification rate and production efficiency of the docking device.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to a docking device for an exhalation valve and a ventilator with the same. Background technique [0002] In the docking device of the exhalation valve in the current ventilator, a paired processing method and a method with a certain amount of flexible adjustment are usually adopted. The pairing processing method generally has a complex structure, and the processing is difficult, and the production cost is also high. The method with a certain amount of flexible adjustment is mainly to use the rigid valve and the sealing ring for docking. In this method, the deformation of the sealing ring is small, and there is generally a certain gap for the smooth insertion of moving parts, so that Air leakage will occur, especially when the movable parts are swinging up and down, the probability of air leakage increases greatly, and the practicability is poor. Contents of the invention [0003]...
