Retainer for laryngeal mask
View Patent ↗An endo-tracheal tube retainer used to facilitate the removal of a laryngeal mask of the type used to facilitate lung ventilation and the insertion of endo-tracheal tubes or related medical instruments through a patient's laryngeal opening is provided. The endo-tracheal tube retainer includes a semi-rigid stylet having proximate and distal ends and a soft curved stylet cap secured to the proximal end. The endo-tracheal tube also includes a connection adapter that is tapered from front to rear for secure insertion within a range of endo-tracheal tubes, removably secured to the distal end.
1. A method for removing an inflatable laryngeal mask from a patient without dislodging any inserted endotracheal tubes or related medical instruments into the patient's laryngeal opening by using a tube retaining device, the method comprising the steps of:
inserting the tube retaining device through an opening in the inflatable laryngeal mask exterior to the oral cavity;
securing the tube retaining device within a proximal end of the previously inserted endo-tracheal tube within said inflatable laryngeal mask;
deflating said inflatable laryngeal mask;
simultaneously withdrawing said deflated inflatable laryngeal mask from the patient's oral cavity and exerting a retaining force on the tube retaining device sufficient to prevent friction from dislodging said endo-tracheal tube; and
sliding the inflatable laryngeal mask off the proximal end of said retaining device.
2. A method for removing an inflatable laryngeal mask from a patient without dislodging any inserted endo-tracheal tubes or related medical instruments into the patient's laryngeal opening by using a tube retaining device, the method comprising the steps of:
securing the tube retaining device within a proximal end of an endotracheal tube;
inserting the endotracheal tube through an opening in the inflatable laryngeal mask;
removing said inflatable laryngeal mask by withdrawing said inflatable laryngeal mask from the patient's oral cavity and exerting a retaining force on the tube retaining device sufficient to prevent friction from dislodging said endo-tracheal tube; and
removing the inflatable laryngeal mask.
3. The method of claim 2 wherein removing the inflatable laryngeal mask comprises separating the tube retaining device from the endotracheal tube and sliding the inflatable laryngeal mask off an end of the tube retaining device.
4. The method of claim 2 wherein removing the inflatable laryngeal mask comprises sliding the inflatable laryngeal mask off a proximal end of the tube retaining device.
5. A method for removing an laryngeal mask from a patient without dislodging any inserted endo-tracheal tubes or related medical instruments into the patient's laryngeal opening by using a tube retaining device, the method comprising the steps of:
inserting an endotracheal tube through an opening in the laryngeal mask;
securing the tube retaining device within the endotracheal tube;
removing the laryngeal mask by withdrawing the laryngeal mask from the patient's oral cavity and exerting a force on the tube retaining device sufficient to prevent dislodging the endo-tracheal tube; and
removing the laryngeal mask.
6. The method of claim 5 wherein removing the laryngeal mask comprises separating the tube retaining device from the endotracheal tube and sliding the laryngeal mask off an end of the tube retaining device.
7. The method of claim 5 wherein removing the laryngeal mask comprises sliding the laryngeal mask off a proximal end of the tube retaining device.
8. A method for removing a laryngeal airway from a patient's oral cavity without dislodging any inserted endotracheal tubes or related medical instruments into the patient's laryngeal opening by using a tube retaining device, the method comprising the steps of:
securing the tube retaining device within a proximal end of an endotracheal tube;
inserting the endotracheal tube through the laryngeal opening;
removing the laryngeal airway by withdrawing the laryngeal airway from the patient's oral cavity and exerting a retaining force on the tube retaining device, the retaining force being sufficient to prevent friction from dislodging said endo-tracheal tube; and
removing the laryngeal airway.
