Description

Technical Field

[0001] The utility model relates to the technical field of tracheotomy surgery, in particular to a device for preventing sputum from splashing. Background Art

[0002] Patients in the intensive care unit of a hospital often experience difficulty coughing up sputum or breathing, and must undergo a laryngeal tracheotomy. After a tracheotomy, sputum is easier to cough up and suction is also more convenient, but a tracheal tube needs to be left in place for a long time. At present, if a tracheotomy patient's condition improves, they do not need a ventilator to assist breathing. In addition to using an airway humidification tube, a piece of medical wet gauze is generally used to cover the tracheotomy site to prevent the respiratory tract from becoming too dry, sputum from splashing, and foreign objects from falling into it. When a tracheotomy patient coughs violently, sputum often splashes onto the bed or onto family members and nurses, and even onto the sheets of other patients several meters away, causing contamination.

[0003] China Utility Model Patent Publication No.: CN213158689U, discloses: a device for preventing sputum splashing of tracheotomy patients, which is easy to disassemble and convenient for cleaning and disinfecting the sputum collecting tray and protective cover. The device for preventing sputum splashing of tracheotomy patients is not convenient for adjusting the ventilation volume and is not convenient for adapting to patients in different conditions.
