Description

Anti-splashing breathing filter and use method thereof

Technical Field

The invention relates to the technical field of medical appliances, in particular to a splash-proof breathing filter and a using method thereof.

Background

In an anesthesia or intensive care unit, in order to facilitate airway management, a patient often performs tracheal intubation or tracheotomy so as to keep an airway unobstructed, relieve airway obstruction and ensure normal performance of lung ventilation function. Similarly, when a tracheal tube or a catheter is required to be subjected to sputum aspiration frequently, severe cough of a patient is often caused due to stimulation to tracheal wall mucosa, respiratory droplets and aerosol are sprayed outwards through the tracheal catheter, and once pathogenic bacteria are carried, cross infection of medical workers and other patients in the same space is easily caused.

Although the existing breathing filter can effectively prevent respiratory tract spray and aerosol from splashing, the tracheal intubation tube core or the sputum suction tube cannot pass through the filtering layer of the breathing filter, so that the sputum suction and tube drawing operation in the tracheal intubation or the catheter cannot be carried out under the condition of keeping the breathing filter.
