Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically to an ophthalmic nebulizer. Background Technology

[0002] With the increasing number of people suffering from eye diseases, the treatment of eye diseases has received more and more attention. In the treatment process, the medication is often dropped directly into the eyes, such as eye drops. However, the process of dropping eye drops is often unpleasant due to shaky hands, inability to control the dosage, and children's lack of cooperation. If you are not careful, you will be "tearful" and waste the medication.

[0003] Furthermore, when applying medication to the eyes, such as using eye drops, the patient needs to lie flat or tilt their head back. If the application time is too long, the patient may experience neck pain and head movements, which will affect the application and greatly restrict the patient's posture, increasing the patient's discomfort.

[0004] Existing postoperative ophthalmic nebulization devices deliver medication to the patient's eyes via atomization. However, these devices are often large and bulky, requiring patients to be near them for each application. Furthermore, after medication is applied, a certain amount of medication residue remains on the nebulizer nozzle. If not cleaned promptly, this residue can form on the nozzle, potentially clogging it over time and affecting the effectiveness of subsequent applications.

[0005] Therefore, developing an ophthalmic nebulizer that is easy to operate and clean is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the present invention provides an ophthalmic nebulizer that is easy to operate and easy to clean.
