Abstract

The invention discloses an antiviral nasal cavity and paranasal sinus decongestant spraying device for treating a cold, which comprises a bottom plate and a liquid medicine storage bottle. By inserting two symmetrically arranged silicone spray nozzles into the nasal cavity of a patient, turning on an electronic atomizer, and pressing a three-way connecting pipe back and forth to compress air through a compressing block so that a return spring contracts, liquid is compressed into a catheter to flow out, and then sprayed into the nasal cavity of the patient after being atomized by the electronic atomizer. The electronically atomized medicine is sprayed out through the spray nozzles and inhaled by the patient, and can reach infected mucosas of the whole nasal cavity and paranasal sinuses, thus achieving a good therapeutic effect. Medicine can reach the sinus cavity, eustachian tube and upper respiratory tract which are hard to reach with ordinary spray, adverse reactions caused by systemic administration are avoided, and local drug concentration is improved. Clinical tests show that the course of the cold can be greatly shortened. By adopting the silicone spray nozzles, nasal mucosa damage possibly caused by a hard plastic spray nozzle is avoided. The antiviral nasal cavity and paranasal sinus decongestant spraying device is especially suitable for children who are prone to the common cold, and has great clinical application prospect.

Description

BL-5526 LU502371 Description Antiviral Nasal Cavity and Paranasal Sinus Decongestant Spraying Device for Treating Cold Technical Field The invention relates to a spraying device, in particular to an antiviral nasal cavity and paranasal sinus decongestant spraying device for treating a cold.
Background Art The common cold is the most common infection that occurs in humans.
Adults catch colds 2-3 times a year on average, 6-8 times for kids.
No western medicine, traditional Chinese medicine or proprietary Chinese medicine has been proved to shorten the natural course of the common cold.
Treatment mainly focuses on relieving symptoms.
Although most patients claim to benefit from treatment, it is just placebo effect for the most part.
At present, the common cold is mainly treated with painkillers and antipyretics.
Studies have shown that these drugs may cause potential harm to children.
Some countries including Canada have restricted children aged 6 and under from taking these drugs.
Symptoms like runny noses can be relieved by taking antihistamines, but adverse reactions such as drowsiness may be caused, and the effect on nasal congestion is limited.
Current cold medicines basically work through systemic administration, but after the first pass elimination of blood circulation and liver and systemic redistribution, the dose reaching pathogenic sites, that is, the congestive nasal cavity and paranasal sinus mucosas is quite limited, so the therapeutic effect is limited.
This is an important reason why no cold medicine available now can shorten the course of the cold, while patients have to suffer from adverse reactions and toxic and side effects of systemic administration.

2. Low local concentration and systemic adverse reactions caused by systematic administration are avoided. This device can realize a high drug concentration at pathogenic sites, and is proven by clinical tests to greatly shorten the course of the disease and lead to minimal systemic adverse reactions, so it has great clinical application prospect. Because cold medicines available in the market cannot shorten the course of the disease and may cause various systemic adverse reactions, someone recommends that colds not be treated. However, there have been many reports of severe leukopenia in patients catching a cold but not treated, and this might be life-threatening. This device will stop cold patients from feeling helpless.
3. The dust cap can be firmly installed and falls off less easily, the silicone spray nozzle can be disassembled and replaced, and the device is easy to clean, saves time and labor force in operation, and has a much better treatment effect.
