The embodiment when in use, the anaesthetic mask 1 cooperate when specifically used air anesthetic together into It exercises and uses, air anesthetic is carrier gas using air or oxygen, can be carried out assisted respiartion and control breathing, specific: patient After completing anesthesia induction, air anesthetic and closed anesthesia mask 1 are attached, when patient breaths, anaesthetize gaseous mixture Inspiratory valve of the body through opening enters in patient body, and when expiration, expiratory valve is opened, while inspiratory valve is closed, and patient is discharged The gas of exhalation；When anaesthetizing work completion, since patient anaesthetizes sb. generally through gas, need to be used for patient's oxygen supply at this time Auxiliary patient carries out breathing because general anesthesia can also cause respiratory muscle to be anaesthetized, and needs after the completion of patient's anesthesia to patient Oxygen supply auxiliary patient respiratory is carried out, in case discomfort occurs during surgery for patient；

How to carry out about the anaesthetic mask 1 using will be described in detail following；We are first inflated air cushion 3 So that air cushion 3 expands, so that patient facial region is close in 1 bottom of mask, for guaranteeing the sealing performance of the mask 1, and The multiple exhaust passages for being set to the longitudinal two sides of mask 1 are closed, (preferable, we are in drain tap and 4 turns of main tracheae Dynamic matching postion is provided with sealing joint strip) because don't fail to guarantee the sealing of mask 1 when carrying out gas anesthesia to patient Property so as not to anesthetic gases leak, to extraneous air born pollution, the mask 1 is then fixed on patient facial region, when doctor is to trouble After the completion of person implements anesthesia induction, oxygen cathete 6 is closed and connect anesthesia tube 5 with air anesthetic by we, air anesthesia Agent will anaesthetize mixed gas and be delivered to anesthesia tube 5 through conduit and enter in main tracheae 4 in communication through anesthesia tube 5, I Set in the initial state, the main tracheae 4 in air inlet pipe 2 be not connected to cylinder 9 and through in main tracheae 4 anesthesia mix Gas directly enters in air inlet pipe 2 through main tracheae 4, and anesthetic gases enter directly into 1 cover of mask through air inlet pipe 2 at this time, Patient enters the anesthesia mixed gas in mask 1 by breathing and implements general anesthesia, when we are set in progress gas anesthesia, Plane locating for flabellum 12 and the first annulus 10, cylinder 9 of several rotational installations between the first annulus 10 and cylinder 9, which is in, hangs down Straight state (referring to shown in attached drawing 3), the anesthesia mixed gas for guaranteeing to enter in air inlet pipe 2 can be entered smoothly In mask 1, so that several flabellums 12 will not interfere the flowing of anesthetic gases, it shall be noted that be at this time patient be directly breathe into Enter to the anesthesia mixed gas in mask 1 and anaesthetized, and nose conduit 7 is not used and carries out breathing anesthetic gases, is worth note again Meaning, ether air anesthesia unit are not to convey anesthetic gases into mask 1 always but cooperate the breathing of patient itself same What step carried out, when the patient inhales, anesthesia inspiratory valve of the mixed gas through opening enters in patient body, when expiration, exhales Flap valve is opened, while inspiratory valve is closed, and the gas that patient breathes out is discharged through air inlet pipe 2, anesthesia tube 5 outward, when to patient Complete anesthesia after, at this time stop anesthesia mixed gas conveying anesthesia tube 5 is closed, and by oxygen cathete 6 be opened for patient into Row oxygen supply；

Since the oxygen come out from oxygen cylinder is pure oxygen, sucking pure oxygen that cannot be single when being supplied oxygen for patient, at this time I Need for mask 1 to be connected to outside air, air cushion 3 is deflated at this time so that between mask 1 and patient facial region generate between Gap is entered in patients with respiratory tract jointly with guaranteeing that outside air can enter the pure oxygen that 1 internal engagement of mask conveys, general right The operation that patient implements general anesthesia is biggish operation, causes its surgery duration longer, patient is when breathing Vapor can constantly be discharged, although part vapor can be evaporate into outside air out of mask 1, since mask 1 is narrow Small space and the lasting progress with operating time, the vapor for causing patient to breathe out are adhered on 1 inner wall of mask, so that Air humidity content in mask 1 increases the comfort level for influencing patient, and if do not cleared up in time these vapor, water steams Gas, which more condenses, forms water droplet and can drip in patient facial region, easily enters in patient nose, impacts safely to patient vitals；

In this programme 1 ontology of mask and air inlet pipe 2 we be made of transparent material, convenient for doctor to patient respiratory situation And in mask 1 vapor observation, we can be by artificially visually observing the aggregate amount of vapor in mask 1, as one kind It is preferred that: it can also be fixedly installed with humidity sensor in mask 1 and humidity sensor is connected with microcontrol processor, and It is provided with warning lamp on mask 1 and warning lamp returns route electronic and is powered, parameter is arranged to microcontrol processor in we, so that When in mask 1 air humidity content be more than we set by normal range (NR) when, humidity sensor issue signal to microcontroller at It manages device and microcontrol processor control warning lamp circuit is connected, so that warning lamp flashes, prompt medical staff；

We pass through lateral distance regulating device and vertical distance adjusting means first nose conduit 7 are moved to patient nostril at this time At position, so that nose conduit 7 is corresponding with the naris position of patient, it is soft at this time since nose conduit 7 is connect through hose 8 with cylinder 9 The fine tuning that pipe 8 can be extended or be shortened accordingly to cooperate 7 position of nose conduit, we are driven by first driving device at this time Dynamic annular ring 13 slide laterally and towards the direction close to main tracheae 4 along air inlet pipe 2, so that make cylinder 9 and main gas Pipe 4 is connected together, the oxygen entered in main tracheae 4 at this time no longer enter in air inlet pipe 2 but through cylinder 9, hose 8, Nose conduit 7 enters directly into patient nostril, we open multiple exhaust passages that the longitudinal two sides of mask 1 are arranged at this time, And motor 14(motor is controlled by 14 controller of motor and is connected with extraneous power supply through conducting wire) starting work, motor 14 is through hyperextension Contracting axis driving be set in cylinder 9 the first transmission device (since motor 14 is fixed in main tracheae 4 and position is constant, so Through being telescopically connected between the first transmission device and motor 14, to cooperate the connection and disengaging of cylinder 9 Yu main tracheae 4), motor 14 The first transmission device is driven through telescopic shaft and then drives several flabellums 12 vertical with plane locating for the first annulus 10 first It is rotated between annulus 10 and cylinder 9, and several flabellums 12 are rotated by certain angle in the first transmission device, so that fan Leaf 12 is no longer normal to plane locating for the first annulus 10 but generates an inclination angle between plane locating for the first annulus 10, After the first transmission device drives several flabellums 12 to rotate special angle, flabellum 12 is no longer rotated, and the first transmission device drives at this time Dynamic cylinder 9 drives rotational installation to synchronize in the first annulus 10 in annular ring 13 and is rotated by several flabellums 12 in turn, First annulus 10, cylinder 9 and several flabellums 12 being rotatablely installed between the first annulus 10 and cylinder 9 can be worked as conduct by this One exhaust fan, the driving of motor 14 at this time should be rotated entirely around annular ring 13, separate in air inlet pipe 2 due to being rotatablely installed The drain tap of 1 one end of mask is connect through several telescopic rods 11 with the first annulus 10, at this time drive of first annulus 10 in motor 14 It is dynamic lower that drain tap is driven to rotate synchronously to open drain tap, at this time in mask 1 the biggish air of humidity by a steady stream not Disconnected discharges mask 1 through drain tap, has gas since exhaust passage is opened fixed placement in its exhaust passage by us Desiccant, outside air enters in mask 1 simultaneously through the gap between several exhaust passages and air cushion 3 and patient facial region at this time And mask 1 is discharged in the biggish air of humidity in mask 1 under the action of several flabellum 12, to realize that dry gas enters Into mask 1, when air humidity content is restored to normal range (NR) in mask 1, humidity sensor is issued at signal to microcontroller Reason device disconnects warning lamp circuit, and trapezoidal medical staff stops exhaust, controls the reversion of motor 14 one by 14 controller of motor Determining to stop working after angle, (14 controller of motor is that motor 14 is controlled by active according to the direction of setting, speed, angle The integrated circuit that degree, response time work) and then multiple flabellums 12 is driven to restore again to locating for the first annulus 10 to put down Face is in plumbness (so that several flabellums 12 do not influence circulation of the gas in air inlet pipe 2), and the first annulus 10 stops at this time It rotates and is also stopped operating therewith by the drain tap that telescopic rod 11 is connect with the first annulus 10 and is in close state, this When and cylinder 9 is separated with main tracheae 4 by first driving device, so that the oxygen in winner's tracheae 4 is entered air inlet pipe 2 simultaneously And enter eventually into mask 1 and supplied oxygen for patient, patient restores the oxygen supply of mask 1 at this time.
