It can be understood that the above scheme can be realized when performing anesthesia air storage bag testing, convenient operation can be achieved, the detection time can be optimized, and the detection and use can be more convenient.

[0021] In this embodiment, the connector body 101 has a mounting portion 102 , and the mounting portion 102 is located below the connector body 101 . The mounting portion 102 facilitates the detection of the bag neck set of the air storage bag.

[0022] Among them, the trachea quick connector 103 is threadedly connected to the connector body 101 and is located at the top of the connector body 101, the air guide nozzle 104 is threadedly connected to the connector body 101 and is located at the bottom of the connector body 101, the annular expansion airbag 105 is fixedly connected to the connector body 101 and is located on the side of the connector body 101 close to the mounting portion 102, and the filter component is arranged between the trachea quick connector 103 and the air guide nozzle 104. The top and bottom of the connector body 101 are provided with threaded cavities to facilitate the installation of the trachea quick connector 103 and the air guide nozzle 104. A metal ring is arranged on the mounting end of the annular expansion airbag 105 to facilitate fixing to the connector body 101 by bolts. The filter component is arranged between the trachea quick connector 103 and the air guide nozzle 104 to detect gas filtration and prevent impurities from entering the detection air storage bag and affecting use.

[0023] Secondly, the connector body 101 also has an air pipe through hole 106 and a binding groove 107. The air pipe through hole 106 is arranged on the connector body 101; the binding groove 107 is located on the mounting portion 102. The air pipe through hole 106 is conducive to the gas pipeline arrangement of the annular expansion airbag 105. The binding groove 107 is arranged at the bottom of the mounting portion 102. In some detection occasions, when the pressure required for the detection is too large, it can be further fixed by a nylon line to ensure the stability of the detection airbag.
