Description

Nasal secretion collecting device capable of being connected to negative pressure

Technical Field

The utility model relates to a nasal secretion collecting device capable of being connected with negative pressure, and belongs to the technical field of medical instruments.

Background

Clinically, the diagnosis of chronic rhinitis and sinusitis is mainly judged according to the clinical symptoms and signs and the medical history of patients, and necessary laboratory diagnosis basis is lacked. The infection, allergy and neuroendocrine causes of rhinitis and nasosinusitis can not be well analyzed, and the rough and ambiguous diagnosis results in the inaccurate administration and poor curative effect. Among them, the lack of a convenient and inexpensive nasal secretion collecting device is an important reason. The cytological analysis, the microbiological analysis and the analysis of characteristic secretory proteins in nasal secretions all determine the diagnosis of different rhinitis and sinusitis. The traditional tools and materials for clinically collecting nasal secretions are different, generally are simple sliver and manually made expanded sponge, negative pressure suction is often not good for collecting the nasal secretions because the secretions are lost, and a simple and convenient standardized collecting device is lacking clinically at present; therefore, there is a need in the art for a nasal secretion collection device that is convenient to use.
