On the rotating element 602 are several evenly distributed non-slip protrusions 6021 arranged; if the female Luer connector 60 and the male Luer connector 59 are to be connected to each other, they are connected to the female Luer connector by means of the rotating element 60 tightened clockwise; the rotating element should be rotated when tightening, with the arrangement of a non-slip projection 6021 on the rotating element 602 the tightening work can be done effectively.

Please refer 12th , the present exemplary embodiment comprises an open ear basin 8th , being on one side of the ear basin 8th a first ear placement groove 81 is provided, with a gun placement groove on the other side 82 is provided, the middle of which is a cavity 83 for collecting the ear cleaning waste water or placing the gun for cleaning the ears, and being the size of the mold cavity 83 sufficient to place the cleaning liquid bottle 2nd and the first ear placement groove 81 in the open ear basin 8th for placing the patient's ears, and with the lower part supported and bumped by a hand, then the liquid supply tube 3rd adjacent to the first ear placement groove 81 and the placement groove 82 connected to the with the liquid supply pipe 3rd connected ear-nose irrigation return nozzle 5 is a female Luer connector 60 connected by a liquid outlet silicone tube 9 inserted into the patient's cochlea to perform cleaning work; if during cleaning the cochlea is completely filled with the cleaning liquid, the cleaning liquid will of course run out, now the cleaning liquid is in the cavity 83 of the ear basin 8th If no cleaning work is done, the gun can flow back into the cavity to clean the ears 83 in the ear basin 8th In summary, the ear basin has two functions that the cavity 83 can hold both the cleaning liquid after the return and the gun for cleaning ears.

When using the gun for cleaning ears, the liquid supply tube, which is designed as a long soft tube, is opened with one hand 3rd aligned with the ear and this protrudes into the cochlea, with the other hand the pistol is held and the ear basin 8th to be supported by another person;

Working principle: with one hand, the liquid supply pipe, which is designed as a long, soft pipe, becomes 3rd aimed at the ear, and this protrudes into the cochlea, with the other hand the pistol 1 held, a nurse should support the ear basin with the hand, the user connects the ear-nose Rinsing return nozzle 59 with the female Luer connector 60 and put it through the liquid outlet silicone tube 9 into the patient's cochlea, the pressure switch 10th on the gun body 14 is pressed several times to the cleaning liquid in the cleaning liquid bottle 2nd successively through the liquid supply pipe 3rd and the liquid outlet silicone tube made of silicone material 9 the ear-nose irrigation return nozzle 5 pour into the patient's cochlea; When the hearing auger is completely filled with the cleaning liquid, the cleaning liquid flows out in the opposite direction and falls after it meets the transparent splash-proof baffle plate 9 in the ear basin 8th a.
