Problems solved by technology

[0003] There are many problems with the existing ear, nose and throat sprayer. The old attending doctor can quickly spray the medicine according to the patient's disease, the angle of spraying the medicine and the contact angle of the spray tube to the human body, etc., but many interns can't grasp the correct method of use. If you can’t grasp the distance of the jet tube to the diseased part, it will often cause the hard contact of the jet tube to the patient’s ear, nose and throat, which will increase the pain of the patient and cause secondary damage. It is in the deep parts such as the ear canal, nasal cavity or throat. The existing device cannot adjust the position of the drug outlet according to the demand, resulting in the inability to spray to the affected area, reducing the effect of drug absorption, and the direction and angle of the spray port cannot be adjusted. The entire device needs to be turned over, which is time-consuming and labor-intensive
