A drug delivery device for otolaryngology

Abstract

The invention discloses a drug delivery device for otolaryngology, which comprises a cylinder body, a docking port, a first one-way valve plate and a second one-way valve plate. There is a liquid storage chamber above, the right side of the liquid storage chamber is provided with a docking port, and the docking port is located on the right side of the cylinder body, and a first one-way valve plate is installed between the docking port and the cylinder body. The bottom of the liquid chamber is provided with a first air bag, and a first pipe body is installed below the first air bag, and the upper end of the extension rod is provided with a mounting ring, and a spray head is provided above the mounting ring, and the spray head passes through The mounting ring is interconnected with the extension rod. The otolaryngology drug delivery device can manually twist the adjusting ring to perform rotational movement on the upper end of the barrel through the connecting ring and the connecting groove, and the rotating adjusting ring can push the extension rod through the thread to perform telescopic movement in the adjusting groove, so It is convenient to adjust the length of the drug delivery device protruding into the nasal cavity, which can avoid stab wounds.

Description

technical field [0001] The invention relates to the technical field of otolaryngology, in particular to a drug delivery device for otolaryngology. Background technique [0002] Otolaryngology includes ear, nose, throat and other parts, which are some parts of the human body that are more prone to disease. Diseases in the above parts often have a serious impact on the daily life of patients, so timely diagnosis and treatment are required, especially acute rhinitis, chronic rhinitis and Sinusitis and other nose-related diseases often need to be dipped with a cotton swab to apply the liquid to the patient. However, the existing cotton swabs that are dipped in the liquid to deliver the medicine often have the following problems: [0003] 1. After taking the liquid medicine through the cotton swab, the patient cannot see the location of the lesion and deliver the medicine during the process of applying the medicine, so the patient cannot accurately grasp the depth of the cotton s...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a drug delivery device for otolaryngology to solve the problem that the patient cannot see the location of the lesion and deliver the drug during the process of applying the drug after the cotton swab is dipped in the drug solution proposed in the background art. It is impossible to accurately grasp the feeding depth of the cotton swab, so it is extremely easy to puncture the mucous membrane in the nostrils, which further aggravates the pain of the patient. At the position of the patient, at the same time, the method of applying the medicine is very cumbersome, and the medicine needs to be repeatedly dipped and then inserted into the nasal cavity, which is likely to cause focal infection of the patient and is inconvenient to use
