Retainer for laryngeal mask
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 though 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 retainer 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 combination of an endo-tracheal tube retainer and an endo-tracheal tube comprising:
an endo-tracheal tube placed through a laryngeal mask and into a patient's laryngeal opening; and
an endo-tracheal tube retainer including:
a semi-rigid stylet rod having proximal and distal ends; and
a connection adapter tapered from a proximal end of said connection adapter to a distal end of said connection adapter and capable of secure insertion within said endo-tracheal tube, said adapter being secured to said distal end of said semi-rigid stylet rod; an exterior surface of said connection adaptor including:
a plurality of longitudinal grooves permitting passage of air and fluids past said endo-tracheal tube retainer after insertion within an endo-tracheal tube; and
a plurality of threads angled to facilitate insertion of said endo-tracheal tube retainer within an endo-tracheal tube, but hindering withdrawal of said endo-tracheal tube retainer from said endo-tracheal tube;
wherein, said endo-tracheal tube retainer is secured to said endo-tracheal tube so that said laryngeal mask can be removed from said patient's oropharynx without dislodging said endo-tracheal tube.
2. The combination of claim 1 wherein the connection adapter is composed of soft, semi-rigid material capable of at least partially traversing through said endo-tracheal tube after positioning within the oropharynx region.
3. The combination of claim 1 wherein said longitudinal grooves are equi-spaced around said connection adapter exterior surface.
4. The combination of claim 3 wherein there are at least four longitudinal grooves.
5. The combination of claim 1 wherein said longitudinal grooves extend from said proximal end of said connection adapter to said distal end of said connection adapter.
6. A combination of an endo-tracheal tube retainer and a laryngeal mask comprising:
a laryngeal mask of the type used to facilitate lung ventilation and the insertion of endo-tracheal tubes or related instruments through a patient's laryngeal opening; and
a endo-tracheal tube retainer including:
a semi-rigid stylet rod having proximal and distal ends; and
a connection adapter tapered from a proximal end of said connection adapter to a distal end of said connection adapter and capable of secure insertion within an endo-tracheal tube placed through said laryngeal mask and into said patient's laryngeal opening, said adapter being secured to said distal end of said solid stylet rod; an exterior surface of said connection adapter including:
a plurality of longitudinal grooves permitting passage of air and fluids past said endo-tracheal tube retainer after insertion within an endo-tracheal tube; and
a plurality of threads angled to facilitate insertion of said endo-tracheal tube retainer within an endo-tracheal tube, but hindering withdrawal of said endo-tracheal tube retainer from said endo-tracheal tube;
wherein, said endo-tracheal tube retainer is secured to an endo-tracheal tube extending into a patient's laryngeal opening so that said laryngeal mask can be removed from said patient's oropharynx without dislodging said endo-tracheal tube.
7. The combination of claim 6 wherein the connection adapter is composed of soft, semi-rigid material capable of at least partially traversing through said endo-tracheal tube after positioning within the oropharynx region.
8. The combination of claim 6 wherein said longitudinal grooves are equi-spaced around said connection adapter exterior surface.
9. The combination of claim 8 wherein there are at least four longitudinal grooves.
10. 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, said laryngeal mask being removed from a patient's oropharynx without dislodging any inserted endo-tracheal tubes or related medical instruments passing through the laryngeal mask into the patient's tracheal tube, said endo-tracheal tube retainer comprising:
a semi-rigid stylet rod having proximal and distal ends; and
a connection adapter tapered from a proximal end of said connection adapter to a distal end of said connection adapter and having a length therebetween; an exterior surface of said connection adapter including:
a plurality of longitudinal grooves running the entirety of said length; and
a plurality of threads angled to facilitate insertion of said endo-tracheal tube retainer within an endo-tracheal tube, but hindering withdrawal of said endo-tracheal tube retainer from said endo-tracheal tube.
