Abstract
Devices, systems, and methods of facilitating airway management with reduced risk of release of droplets and aerosolized pathogens from the lungs of a patient are disclosed, including a bronchoscope adapter for an endotracheal tube, an endotracheal tube with integral bronchoscope adapter, an endotracheal intubation mask system, a laryngeal mask airway-specific mask system, and a quick-seal laryngeal mask airway-specific mask system.
Claims20
A sealed access endotracheal tube adapter configured to attach to an endotracheal tube, the adapter comprising:
- a) an access port comprising a first tube ending in a proximal entry port and a distal endotracheal tube connector, the proximal entry port configured to receive at least medical instrument and the distal endotracheal tube connector configured to couple to a proximal end of the endotracheal tube;
- b) a selectively pressurized balloon-valve seal positioned within an inner surface of the first tube distal to the proximal entry port, the balloon-valve seal comprising at least two balloons attached to at least a portion of the inner surface of the first tube, wherein the balloon-valve seal assumes a sealed configuration when the at least two balloons are inflated and the balloon-valve seal assumes an open configuration when the at least two balloons are deflated;
- and
- c) a ventilation system connector comprising a second tube comprising a distal end operatively coupled to the first tube between the balloon-valve seal and the distal endotracheal tube connector and a proximal end ending in a ventilation system connector, the ventilation system connector configured to couple to a ventilation device.

An intubation mask system, comprising:
- a) a mask comprising at least one central opening, the least one central openings defining at least one adjacent, noncontiguous port, wherein each of the ports is configured to receive at least one medical instrument:
- b) at least one balloon-valve seal, each balloon-valve seal positioned within each of the at least one ports, each balloon-valve seal comprising at least two balloons, wherein the balloon-valve seal assumes a sealed configuration when the at least two balloons are inflated and the balloon-valve seal assumes an open configuration when the at least two balloons are deflated;
- and
- c) a scaffold and a plurality of removable head straps, each head strap comprising a first end attached to the mask and a second end attached to the scaffold, wherein the mask, the scaffold, and the plurality of straps are configured to secure to a head of a patient with the mask positioned on the patient's face and the scaffold positioned behind the head of the patient.
1 more element
A quick-seal laryngeal mask airway-specific system, comprising
- a) a patient-fitted mask frame defining a central opening;
- b) a selectively inflatable cushion coupled to a proximal surface of the mask frame, the cushion configured to seal against a patient's face;
- c) a collapsible insertion channel comprising a flexible tubular membrane comprising a proximal end and a distal end, a mask fitting coupled to the proximal end of the flexible tubular membrane, and an inlet port attached to the distal end of the flexible tubular membrane, where
- i) the mask fitting is further coupled to a distal surface of the mask frame;
- ii) the inlet port is configured to receive at least one of a laryngoscope and at least a portion of a laryngeal mask airway device;
- iii) the insertion channel is configured to assume an extended configuration wherein the flexible tubular membrane is extended distally between the inlet port and the mask fitting and the insertion channel is further configured to assume a collapsed configuration wherein the inlet port is reversibly coupled to the mask fitting with the flexible tubular membrane stowed therebetween, and
- d) a balloon-valve seal positioned within the inlet port, the balloon-valve seal comprising at least two balloons, each balloon having a low-friction surface, wherein the balloon-valve seal assumes a sealed configuration when the at least two balloons are inflated and the balloon-valve seal assumes an open configuration when the at least two balloons are deflated.
