The concentration of China's medical device industry is low, more than 90% of the manufacturers are small and medium-sized, and most of the cooperation objects are hospitals, so the market popularity of Aipeng Medical is not high. In fact, Aipeng Medical entered the field of pain management and nasal care earlier, mastering core technologies such as physiological seawater preparation and atomization quantitative spray, and also participated in the compilation of the industry standard of "portable electric infusion pump".

Nasal irrigation devices belong to Class II medical devices, and in order to be sold in the market, they must have a national Class II medical device product registration certificate. Aipeng Medical has 10 Class II medical device registration certificates, and has passed the quality management system certification of ISO9001 and ISO13485, and its "Nuosiqing" brand nasal spray is mainly sold to individuals through e-commerce platforms, and in China's spray nasal irrigation device market, Nuosiqing has a market share of more than 30%, and Nose Lang and Baoen occupy the top three positions in the industry, and the brand strength should not be underestimated.

Compared with the richness and refinement of the product, Northqing is inferior to the nose, and there is only one kind of packaging for the quantitative pump, which is divided into 50ml children's and 80ml adults, but it is intimately packaged in a non-pressure bottle, which can be used after the water bath is warmed, and the nasal cavity is more comfortable. The products of the Bowen brand are more homogeneous, so they are not considered for inclusion in the list.
