Compared with the prior art, the invention provides an inhalation type anaesthetic mask, which has the following beneficial effects:

1. this suction-type anaesthetic mask, pass through in pipeline one gets into pipeline two through anaesthetic gas, gaseous messenger pipeline two volume inflation, the recess evagination of inflation promotion sealing washer bottom surface through pipeline two, anaesthetic gas is discharged to cover body one in through pipeline four and is inhaled by patient ' S nasal cavity, can say by P ═ F/S, reduce the bottom surface of sealing washer and the area of contact of patient face, it is certain at the pulling force that the elastic cord provided, increase the pressure of sealing washer and patient face, reduce because of the deformation of rabbit lip patient face lead to the face mask and patient face laminating not closely make anaesthetic gas leak the risk, strengthen cover body one and patient face ' S leakproofness, effectively reduce anaesthetic gas ' S leakage, prevent to lead to anaesthetic dose inadequately because of anaesthetic gas leaks, influence the anaesthetic depth, influence the operation.

2. This suction-type anaesthetic mask promotes the recess evagination of sealing washer bottom surface through the inflation of pipeline two, and the gas that gets into in pipeline two when pipeline one is more, and pipeline two is expanded big more, and the leakproofness of reinforcing patient face and cover body one effectively reduces the risk of leaking of anaesthetic gas, avoids volatilizing to the air because of anaesthetic gas is in, endangers medical staff's healthy.

3. The inhalation type anaesthetic mask collects the exhaled air through the mask body I and guides the air into the vertical pipe II through the graduated scale, the vertical pipe II conveys the air which is exhaled by a patient and is mixed with anaesthetic gas into the shell III, the examining information shows that the inhalation type anaesthetic mask mostly adopts the anfluroether as the anaesthetic, the density of the anfluroether is lower than that of the air at room temperature, when the air mixed with the anfluroether enters the shell III, the air is at the lower layer of the shell III due to the low density of the anfluroether, the anfluroether is at the upper layer of the shell III, the anfluroether gas at the upper layer is exhausted into the shell II through the vertical pipe I and pushes the baffle II to turn over the extension spring I through the pipeline III, the anfluroether gas enters the shell I, the air which is exhaled by the patient and is mixed with the anfluroether gas is separated, the anfluroether is recycled, the waste of resources is avoided, and the, the waste gas is prevented from being accumulated in the first cover body to influence the health of the patient, and the safety of the whole inhalation type anaesthetic mask is improved.

4. This suction-type anaesthetic mask, it overturns to overturn left in pipeline two to promote baffle three through the anesthetic gas, baffle three upset drives a pulling slider of connecting rod one and slides and extension spring two in the round hole of pipeline two, make anesthetic gas get into in the casing two, only when patient breathes in, the gaseous reduction pressure of cover body one internal gas reduces, the gaseous upset that could promote baffle three that flows through in the pipeline one, gas in the pipeline one can only be to two internal flows of pipeline, and gas in the pipeline two can not be like a pipeline one internal reflux, when effectively preventing patient from exhaling, waste gas flows back to in the pipeline one, cooperation anaesthetic reflux unit, retrieve the anaesthetic, waste gas shifts, improve the utilization ratio of mask to anesthetic gas.

5. This inhalation type anaesthetic mask, the gas temperature through patient's exhalation is higher than the temperature of standpipe one, and the gas of patient's exhalation is through the condensation of baffle lower surface, because baffle slope right, the comdenstion water can be through the water conservancy diversion flow direction guiding gutter of baffle one in, collects through concentrating the vapor of exhaling gas, prevents effectively that the comdenstion water from condensing into the water droplet on cover body inner wall, flows back to patient's nasal cavity, causes patient's lung to choke water, improves inhalation type anaesthetic mask's security.

6. The inhalation type anaesthetic mask has the advantages that the volume of gas in the shell II is increased to push the cylinder II to move upwards in the cylinder I by the gas flowing out of the vertical pipe I into the shell II, the amplitude of the upwards movement of the cylinder II is read by the graduated scale, after the inhalation anaesthetic mask is inhaled by a patient, the patient gradually enters a sleeping state, the breathing depth and the frequency of a sleeping state and a waking device of the patient are different, the anaesthetic depth of the patient can be visually reflected by the amplitude of the upwards movement of the cylinder II in the cylinder I and the frequency of the upwards movement and the downwards movement of the cylinder II, if the upwards movement amplitude and the upwards movement frequency of the cylinder II are increased, the anaesthetic degree of the patient is reduced, at the moment, the amount of anaesthetic can be properly increased if the operation is not completed, the operation is continuously completed, and after the operation is completed, the moving distance and the frequency of the cylinder II can reflect the resuscitating degree, timely adjustment is realized, and the resuscitation state of the patient can be conveniently observed.

7. This suction-type anaesthetic mask, through will blow the riser through the anaesthetic gas that comes from the intake pipe and drive ring one rotatory in pivot one, the rotation of riser one can be halved from the anaesthetic gas that pipeline three backward flows come and the gas mixture that comes from the intake pipe, makes the gas mixture more even, improves the anesthesia effect to patient.

8. This suction-type anaesthetic mask through because whole device is disposable, can concentrate after the use and collect the processing, avoids flowing the processing because of using the machine to patient's expired gas, needs the inside postoperative disinfection of machine, reduces the work load in later stage, resources are saved.
