The inboard welding of metal sleeve 14 has water wheel 1401, and metal sleeve 14 left side inside is fixed with inner tube 1402, and shower nozzle 1403, the design of above-mentioned structure is all welded to inner tube 1402 inboard, make the effectual in-process that water wheel 1401 is rotatory drive inner tube 1402 and shower nozzle 1403 simultaneously rotatory, thereby can effectually evenly spray out the inboard air antiseptic solution of inner tube 1402 under the rotatory effect of shower nozzle 1403, and then utilize the effectual air to local disinfection of antiseptic solution of even spraying to handle.

The working principle of the embodiment is as follows: when the safe and comfortable type suction aid for the respiratory medicine is used, firstly as shown in figure 1 and figures 5-8, the whole suction aid is quickly taken to the side of a required inspiratory patient through a handle at the upper end, then the fixing frame 6 is sleeved through the upper part of the forehead and the chin of the patient, then the air outlet pipe 4 is connected with the clamping groove 501 at the lower inner side of the connecting pipe 5 in a sealing and clamping way through the air nozzle 402, then the air outlet pipe 4 is fixedly clamped with the connecting pipe 5 at the front side of the lower part of the fixing frame 6, and the intubation tubes 502 at the upper part of the connecting pipe 5 are inserted into the inner sides of two nostrils of the patient, because the head sizes of each patient are different, in order to avoid that the patient turns over under the unclear condition when breathing through the suction aid, the intubation tubes 502 are separated from the nose and can not absorb air, so that the symptoms of life crisis can be caused, at the moment, the conical gear set 8 and the screw rod 9 can be driven to rotate simultaneously by manually rotating the rotating rod 7, the slider 901 and the limiting plate 902 are driven to be matched with the connecting column 601 to move downwards through the rotation of the screw rod 9, so that the inserting tube 502 in the nose of a patient can be effectively fixed through the adjustment of the limiting plate 902 according to the patient with different head sizes in the downward movement process of the limiting plate 902, the inserting tube 502 in the nose of the patient is not easy to loosen when the patient turns over, and the phenomenon that the face of the patient has deep indentations due to the use of a conventional head surrounding fixing mode in the long-term inhalation assisting process of the patient is avoided, so that a lot of convenience is brought to the patient;

after the above steps are completed, at this time, the external air needs to be pumped into the inner side of the air bag 10 and the patient needs to be assisted with inhalation, because the environment of each patient needing to be rescued and assisted with inhalation is different, for example, the environment of some patients is relatively bad, all the air around the patient is viruses, so that the external air cannot be directly sent into the lung of the patient through the connecting mechanism by using the air pump, and it is inconvenient to assist with inhalation to the patient at regular time and quantity when using the air pump, so that the patient has a very difficult problem of shortness of breath, for solving the problem, the specific operation steps are as shown in fig. 1-4, firstly starting the water pump 12 inside the liquid tank 11, so that the air disinfectant inside the liquid tank 11 enters the inner side of the water outlet pipe 13, and then enters the metal sleeve 14 through the water outlet pipe 13, and then driving the water wheel 1401, the inner pipe 1402 and the spray nozzle 1403 to rotate at the same time, therefore, the air disinfectant inside the inner tube 1402 can be uniformly sprayed out during the rotation of the nozzle 1403, and then the air in a local range can be effectively sterilized by the uniformly sprayed disinfectant, then the servo motor at the rear side of the housing 1 is started to drive the main shaft 2 to rotate, the main shaft 2 rotates to drive the chain wheel 202 and the driven shaft 203 to rotate simultaneously, so that the upper and lower half gears 201 are effectively driven to rotate simultaneously by the simultaneous rotation of the chain wheel 202 and the driven shaft 203, and further the guide rack plate 303 and the piston 301 are matched with the fixed cylinder 3 to reciprocate left and right by the effective driving of the two half gears 201 during the simultaneous rotation, and then the air outside the air is guided into the air bag 10 and the inner side of the fixed cylinder 3 at the right side by the matching of the first button air valve 302, the second button air valve 304 and the sponge 101 at the left side during the left and right movement of the piston 301, the sponge 101 is used for filtering air disinfected on the left side to prevent disinfectant in the air from being sucked into the lung of a human body, in addition, under the pressure that the piston 301 is matched with the fixed cylinder 3 to move left and right, the disinfected air enters the inner side of the air outlet pipe 4 in a timed and quantitative mode, and is matched with the third button air valve 401 and the air nozzle 402 to be led into the inner side of the connecting pipe 5 in a timed and quantitative mode, so that the air enters the intubation tube 502 through the connecting pipe 5 and then is sent into the respiratory tract of the nasal cavity in a timed and quantitative mode till the lung, further, the third button air valve 401 can prevent the air from flowing back to the inner side of the air outlet pipe 4 through the intubation tube 502 to pollute the air in the air outlet pipe 4 and the inside of the patient when the patient exhales, the structure enables the patient to breathe freely in the timed and quantitative mode by matching with the suction aid in an unobtrusive state, and brings comfort to the patient, and the treatment and the rapid rehabilitation of the patient are facilitated, which is the working principle of the patient, so that a series of work is completed.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
