The working principle is as follows: as shown in fig. 1, firstly, a medicine bottle containing medicine liquid is screwed on the butt joint port 4, as shown in fig. 1, the cover body on the receiving cavity 2 at the lower end of the cylinder body 1 is opened, then the second air bag 8 is taken out from the receiving cavity 2, then the second air bag 8 is pinched and pressed, the pressed second air bag 8 conveys air into the first air bag 6 through the first pipe body 7, at this time, the first air bag 6 is swelled in the liquid storage cavity 3, the air in the liquid storage cavity 3 pushes the second one-way valve plate 10 to be sprayed out through the second pipe body 13, the mounting ring 19 and the medicine spraying head 20, then the pressed second air bag 8 is loosened, as shown in fig. 4 and 6, at this time, the second one-way valve plate 10 performs reverse rotation movement on the cylinder body 1 through the mounting shaft 11 under the pushing of the vortex spring 12, at this time, the second one-way valve plate 10 cooperates with the partition plate 9 to close the liquid storage cavity 3, when the second air bag 8 is loosened, the air in the first air bag 6 can flow back into the second air bag 8 through the first pipe body 7, the volume of the first air bag 6 is reduced, so that the liquid storage cavity 3 at the moment is in a negative pressure state, as shown in fig. 1, the negative pressure environment in the liquid storage cavity 3 adsorbs the first one-way valve plate 5, so that the first one-way valve plate 5 at the moment rotates leftwards through the mounting shaft 11 and the scroll spring 12 to be opened under the action of the negative pressure environment, so that the liquid medicine in the medicine bottle flows into the liquid storage cavity 3 through the butt joint 4 until the pressure in the liquid storage cavity 3 is recovered, after the pressure in the liquid storage cavity 3 is recovered, the scroll spring 12 pushes the first one-way valve plate 5 to rotate through the mounting shaft 11 to be reset to seal the butt joint 4, and the liquid medicine at the moment is added;
according to the illustration in fig. 1, after the liquid medicine is added into the liquid storage cavity 3, the patient holds the barrel 1 with one hand to approach the nasal cavity, then the other hand pushes the adjusting ring 16 at the upper end of the barrel 1, the adjusting ring 16 performs the rotation motion at the upper end of the barrel 1 through the connecting ring 17 and the connecting groove 18, according to the illustrations in fig. 1 and 5, while the adjusting ring 16 performs the rotation motion, the adjusting ring 16 at this time pushes the extension rod 15 to perform the telescopic motion at the inner side of the adjusting groove 14 through the screw thread, according to the illustrations in fig. 1 and 3, the adjusting groove 14 with the rectangular inner wall can limit the rotation direction of the extension rod 15, so as to ensure that the extension rod 15 performs the stable telescopic motion, and the extension rod 15 performing the telescopic adjustment drives the mounting ring 19 and the medicine spraying head 20 to extend into the nasal cavity of the patient, when the extension rod 15 drives the mounting ring 19 and the medicine spraying head, at this time, the adjusting ring 16 is stopped being screwed, so that the extension rod 15 does not perform the telescopic movement any more, and the positions of the mounting ring 19 and the pesticide spraying head 20 are fixed;
according to fig. 1, after the positions of the mounting ring 19 and the medicine spraying head 20 are adjusted to be close to the focus position, the second air bag 8 is pinched by the hand, so that the gas in the second air bag 8 can flow into the first air bag 6 through the first tube 7, at the same time, the first air bag 6 is swelled in the liquid storage cavity 3, so that the first air bag 6 pushes the medicine liquid to push the second check valve plate 10 open, the medicine liquid can flow into the second tube 13, and finally the medicine liquid is smeared on the nasal cavity focus position of the patient through the second tube 13, the mounting ring 19 and the medicine spraying head 20, after the medicine liquid is smeared for one time, the pinched second air bag 8 is released, at the same time, the second check valve plate 10 loses the pushing force of the medicine liquid, according to fig. 4 and 6, the vortex spring 12 pushes the second check valve plate 10 to rotate reversely through the mounting shaft 11 to close the partition plate 9, according to fig. 1, while the second air bag 8 is released, the gas in the first air bag 6 flows back into the second air bag 8 through the first tube 7, the volume of the first air bag 6 is reduced again, so that the liquid storage cavity 3 is in a negative pressure state again, as shown in fig. 1, the negative pressure environment in the liquid storage cavity 3 adsorbs the first check valve plate 5 again, the first check valve plate 5 rotates leftwards through the mounting shaft 11 and the vortex spring 12 under the action of the negative pressure environment to open, so that the liquid medicine in the medicine bottle flows into the liquid storage cavity 3 through the butt joint port 4 until the pressure in the liquid storage cavity 3 recovers, after the pressure in the liquid storage cavity 3 recovers, the vortex spring 12 pushes the first check valve plate 5 to rotate through the mounting shaft 11 to recover to seal the butt joint port 4, the liquid medicine at the moment is added again, and the liquid medicine of the medicine feeding device can be repeatedly applied and supplemented only by repeatedly pressing and loosening the second air bag 8, the device avoids the need of repeatedly dipping the liquid medicine for use, is simple, convenient and efficient, and reduces the possibility of wound infection, thus the device for the administration in the department of otorhinolaryngology is convenient to use.
