TECHNICAL FIELD
[0001] The present application relates to the technical field of medical devices, more particularly to a disposable self-adaptive tracheostomy tube port plugging device. BACKGROUND
[0002] Tracheostomy is a surgical procedure in which an incision is made in the neck and a tracheostomy tube is inserted into the trachea, with the purpose of maintaining the patency and cleanliness of the airway. Tracheostomy has both therapeutic and prophylactic purposes, and is mainly used for upper airway obstruction, lower airway secretion retention, central or peripheral respiratory depression, and cardiopulmonary insufficiency, etc.
[0003] After the patient meets the extubation criteria, the tracheostomy tube needs to be removed to restore the patient's normal respiratory function and language ability. Before extubation, a plugging test needs to be performed using a plugging tool to determine whether the patient can breathe through the upper airway. The current plugging tools are self-made by clinical medical staff, including plugging with a cotton swab wrapped in adhesive tape, plugging with a processed syringe, plugging with a Murphy drip tube cut from an infusion set, and direct plugging with multiple adhesive tapes. These plugging methods require the plugging tool to be completely removed before sputum can be suctioned from the tracheostomy tube port, resulting in a high difficulty in unblocking, especially for the multiple adhesive tape plugging method, which also leaves adhesive residue on the tracheostomy tube, requiring a second cleaning of the tracheostomy tube. SUMMARY
