When the trachea cannula is used, one end of a trachea far away from a trachea connector can be matched with a laryngoscope to be sent into a trachea, and then the trachea is used for inflating the inflatable balloon, so that the inflatable balloon is inflated, and the inflatable balloon is contacted with the trachea to fix the position of the trachea cannula. The auxiliary breathing device simulates the breathing of a normal person, oxygen can be fed into the airway through the airway, and when carbon dioxide is required to be discharged from the airway, the carbon dioxide is discharged through the airway and the auxiliary breathing device. When the air duct is required to be pulled out, the air in the inflatable balloon is pumped out through the air pump, the inflatable balloon is retracted and is not contacted with the inner wall of the air duct any more, and an operator can slowly pump out the trachea cannula.
The auxiliary breathing device and the tracheal cannula together form an anesthesia ventilation device, and the existing anesthesia ventilation device has the following problems: in the general anesthesia state, the patient has no breathing capacity, so the breathing frequency of the patient can be completely determined through the frequency of the auxiliary breathing device, but with gradual disappearance of the anesthesia effect, the spontaneous breathing capacity of the patient is gradually restored, at this time, the situation that the breathing frequency of the patient is inconsistent with the auxiliary breathing frequency of the auxiliary breathing device can possibly occur, for example, when the patient needs to exhale carbon dioxide spontaneously, the auxiliary breathing device oxygenates in the airway of the patient, which can lead to suffocation of the patient and seriously affect the life of the patient.

The air inlet one-way valve clack and the air outlet one-way valve clack are positioned at one side of the far end of the inflatable air bag. The air inlet one-way valve clack and the air outlet one-way valve clack are both made of rubber materials.
The inflatable airbag comprises an inner wall and an outer wall of an annular structure, item 16 in the figure shows the inner wall of the inflatable airbag, item 17 shows the outer wall of the inflatable airbag, the inflatable airbag further comprises an end connecting wall arranged at the proximal end and the distal end of the inner wall, the inflatable airbag 7 is in rotary fit with an air duct, the periphery of the air duct is provided with a mounting annular groove, the inflatable airbag is rotationally assembled in the mounting annular groove, as shown in figure 1, the left channel wall of the air inlet channel is provided with an air outlet 9, the right channel wall of the air outlet channel is provided with an air charging port 8, the inner wall of the inflatable airbag is provided with an airbag air port 13 which is independently matched with the air outlet or the air charging port, the diameters of the air outlet 9 and the air charging port 8 are smaller than the diameters of the airbag air port 13, the air bag air port is provided with an airbag air valve flap 10 connected with the inflatable airbag at the proximal end, the air bag air port valve flap is made of an elastic material, and in the embodiment, when the air bag is communicated with the air charging port, the air bag is inflated into the air outlet channel 6, the air valve flap distal end of the air bag valve flap can swing towards the axis direction far away from the air duct; when the air bag port is communicated with the air outlet, the air inlet channel is pumped, and the far end of the valve clack of the air bag port swings to the inner side of the air duct towards the axis direction of the air duct so as to open the air bag port.
The use process of the anesthesia ventilation device is as follows: firstly, the far end of an air duct of an air pipe cannula is inserted into an airway of a patient by matching with a laryngoscope, the air duct is rotated, an inflation port of an expiration channel is communicated with an air duct port on the inner wall of the air duct, a second air pipe connector at the near end of the expiration channel is connected with an inflator pump to inflate towards the expiration channel, gas cannot enter the airway of the patient through the expiration channel due to the action of an expiration unidirectional valve clack, under the action of air pressure, the lower end of an air duct port valve clack swings towards the outer wall of the air duct to open the air duct port, at the moment, the air duct port valve clack acts as an air inlet unidirectional valve to inflate the air duct, the outer wall of the air duct is expanded to be in contact with the inner wall of the airway of the patient, as shown in fig. 1, therefore, the position of the air duct is regulated, the air pressure in the air duct is insufficient to enable the lower end of the air duct port valve clack to pass through the inflation port to the inner side of the air duct, and the air duct port valve clack is in sealing fit with the inflation port.
The breathing machine works, the breathing machine conveys oxygen to the airway through the air inlet channel, and specifically, the breathing machine intermittently supplies oxygen to the air inlet channel, oxygen enters the airway through the air inlet one-way valve clack every time, although partial oxygen is discharged through the expiration channel, the patient still can obtain corresponding oxygen supply due to the large cross section area of the air inlet channel, the oxygen supply enables the lung of the patient to expand, the lung of the patient resets in the oxygen supply gap of the breathing machine, and the expired carbon dioxide is discharged through the expiration one-way valve clack and the expiration channel, so that the patient is in a general anesthesia state and is in an operation mode without spontaneous respiratory consciousness. Along with the lapse of time, the gunpowder effect diminishes gradually, and the patient begins to resume spontaneous respiratory consciousness, and if patient's respiratory rate is inconsistent with the intermittent type oxygen supply frequency of breathing machine, the carbon dioxide that patient's spontaneous breathing produced also can discharge smoothly through expiration passageway, avoids carbon dioxide not to discharge smoothly and the suffocating that arouses, breathes unsmoothly problem. The far end of the air inlet channel is longer than the exhalation channel, so that the far end of the air inlet channel is softer and is easier to mould into an arc shape, and the intubation process is convenient; on the other hand, oxygen is supplied to the airway more conveniently.
When the patient is treated and tube drawing is needed, the air duct is rotated, the air outlet of the air inlet channel corresponds to the air outlet of the inflatable air bag, as shown in fig. 2, at the moment, the first air pipe interface at the proximal end of the air inlet channel is connected with the air pump to pump air to the air inlet channel, negative pressure generated by air pumping does not act on the air passage of the patient due to the action of the air inlet unidirectional valve clack, but negative pressure generated by air pumping acts on the air bag air outlet valve clack, the air bag air outlet valve clack generates elastic deformation, the lower end of the air bag air outlet valve clack turns inwards to cross the air outlet to the inner side of the air duct, as shown in fig. 2, air in the inflatable air bag is discharged, and the air bag is retracted, so that the air duct can be slowly pumped out. According to the invention, an inflation pipeline which is independently connected with the inflation air bag is not required to be arranged, and the inflation and deflation of the inflation air bag are realized by utilizing the cooperation of the expiration channel and the air inlet channel, so that the product structure is simplified, and the use is convenient.
