Description

A phototherapy instrument for rhinitis

technical field

The invention relates to the technical field of medical devices, in particular to a phototherapy instrument for rhinitis.

Background technique

Rhinitis is treated with oral antihistamines and nasal steroids. At the same time, low-energy red light or near-infrared light is believed to have biochemical, cellular, histological, and functional effects. The heat generated by light can promote blood circulation in the nasal cavity, so light therapy is also used in the treatment of rhinitis. Moreover, light therapy is easy to use, safe and effective, and is welcomed by most rhinitis patients.

At present, there are mainly two types of phototherapy products for rhinitis in the market: one is professional equipment used in hospitals, which is characterized by high energy of light irradiation (usually >20mW per nostril), large volume and high price. Special personnel are required to operate and use. The other category is a portable rhinitis phototherapy device for home use. This product has lower radiation energy than professional equipment in hospitals (usually the light radiation energy of each nostril ≤ 10mW), and is mainly used to relieve the discomfort caused by rhinitis to patients. Or it can be used in conjunction with drugs to speed up the treatment process. Although the effective optical power of home rhinitis phototherapy equipment is slightly lower than that of professional equipment used in hospitals, patients can achieve the same light radiation measurement by increasing the use time.
