[0002] Otorhinolaryngology is a surgical discipline that diagnoses and treats the ears, nose, pharynx, larynx and related head and neck areas. For ENT patients, they need to use an applicator to apply medicine to the ears, nose and throat regularly to speed up the recovery of the affected area.

[0003] However, in the process of using the drug delivery and application device in the prior art, the ointment is usually pushed to the lesion through a needle tube or a medicine bottle. Since the drug outlets of the needle tube and the medicine bottle are mostly straight-cylindrical, the accuracy is low. Therefore, in the process of applying the medicine, in order to ensure that the lesion is covered, more ointment is often required to be squeezed in, which not only causes waste of ointment, but also makes the patient uncomfortable, and it is difficult to ensure the accuracy of the medicine application;

[0004] Moreover, since the inner wall of the ear, nose and throat is mostly circular, when multiple lesions appear on the same circular inner wall, it is often difficult to cover them all at once because the angle of the drug outlet cannot be adjusted. This undoubtedly increases the difficulty of operation, affects the patient's medication application, and is difficult to meet multiple medication application needs;

[0005] In view of the above technical defects, a solution is now proposed. Utility Model Content

Since the drug outlets of the syringe and the medicine bottle are mostly straight-cylindrical, the accuracy is low. Therefore, during the drug application process, in order to ensure that the lesion is covered, more ointment is often required to be squeezed in, which not only causes a waste of ointment, but also causes discomfort to the patient and makes it difficult to ensure the accuracy of drug application.

[0026] See also Figure 1 - Figure 3 As shown, this embodiment is a drug-drug applicator for ENT care, including a fixed tube 1, a connecting tube 2 is fixedly installed on the top of the fixed tube 1, an applicator assembly 3 is movably installed inside the fixed tube 1, a medicine storage tube 101 is fixedly installed inside the fixed tube 1, the top of the medicine storage tube 101 is movably connected to the applicator assembly 3, a push rod 102 is movably installed inside the medicine storage tube 101, a sealing block 103 is fixedly installed on the top of the push rod 102, and one end of the push rod 102 away from the sealing block 103 extends to the outside of the fixed tube 1.

[0027] The smearing assembly 3 includes a rotating block 301 and a drug outlet pipe 302. The drug outlet pipe 302 is fixedly mounted on the top of the rotating block 301. The rotating block 301 is spherical. The rotating block 301 is movably mounted on the top of the connecting pipe 2. The top of the drug outlet pipe 302 is bent.

A plurality of rotating grooves 104 are opened on the circumference of the outer wall of the fixed tube 1. The rotating ring 305 is movably installed inside the fixed tube 1. The rotating ring 305 is located at the rotating groove 104. The rotating ring 305 is rotated inside the fixed tube 1 by moving the rotating groove 104 to adjust the position of the rotating block 301.

[0031] The rotating groove 104 is arranged near one end of the fixed tube 1 away from the connecting tube 2, and the medicine storage tube 101 is located at the center of the rotating ring 305. The medicine storage tube 101 is movably connected to the rotating ring 305, wherein the medicine storage tube 101 is movably connected to the rotating block 301 through a rotating joint, wherein the rotating joint is a prior art, and its specific type and connection method are not described in detail here, and it is not drawn in the figure.

[0032] When there are multiple lesions, the rotating ring 305 is rotated by the rotating groove 104, and the connecting rod 304 is used to drive the rotating block 301 to rotate synchronously, so that the medicine outlet position of the medicine outlet tube 302 can be adjusted without taking out the fixed tube 1, so as to achieve medicine application on multiple lesions and meet various medicine application needs.

[0033] In combination with Example 1 and Example 2, through the coordinated use of the medicine storage tube 101 and the medicine outlet tube 302, the fixed tube 1 is inserted into the patient's ear, nose and throat, the medicine outlet tube 302 is moved to the lesion and then the push rod 102 is pushed to squeeze the ointment out from the medicine outlet 303. The curved medicine outlet tube 302 is used to ensure the accuracy of medicine application. When there are multiple lesions, the rotating ring 305 is rotated by the rotating groove 104, and the connecting rod 304 is used to drive the rotating block 301 to rotate synchronously. In this way, the medicine outlet position of the medicine outlet tube 302 can be adjusted without taking out the fixed tube 1, so that medicine can be applied to multiple lesions and meet various medicine application needs.

[0034] The working process and principle of the utility model are as follows:

[0035] First, the fixing tube 1 is inserted into the patient's ear, nose and throat, the medicine outlet tube 302 is moved to the lesion, and then the push rod 102 is pushed to squeeze the ointment out of the medicine outlet 303. The curved medicine outlet tube 302 is used to ensure the accuracy of medicine application.

[0036] Furthermore, the rotating ring 305 is rotated by the rotating groove 104, and the connecting rod 304 is used to drive the rotating block 301 to rotate synchronously, so that the medicine outlet position of the medicine outlet tube 302 can be adjusted without taking out the fixed tube 1, so as to achieve medicine application to multiple lesions and meet various medicine application needs;

[0037] In summary, the present invention provides a coating assembly 3 that ensures the accuracy of drug application and also enables free adjustment of the angle of the drug outlet 303 to meet various drug application requirements.
