Abstract

A removable fiberoptic adapter is secured onto a respiratory-device, such as a laryngeal mask airway (LMA) or a ventilating airway mask, to allow for endoscopes to be inserted through the LMA while maintaining a connection to an oxygen source to sustain the patient as the patient breathes. The removable fiberoptic adapter includes an airway tube, an oxygen port, a carbon dioxide outlet, an implement port, and an adapter plug. The oxygen port and the carbon dioxide outlet allow for the introduction of air or oxygen and the removal of carbon dioxide for respiration of the patient. The oxygen port and the carbon dioxide outlet are laterally connected to the airway tube. The implement port allows for the insertion of endoscopes or other medical implements through the respiratory-device. The adapter plug engages the implement inlet in order to restrict fluid flow through the implement inlet.

DETAIL DESCRIPTIONS OF THE INVENTION

[0014] All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.

[0015] The present invention is a removable fiberoptic adapter for a respiratory-device, such as a laryngeal mask airway (LMA) or a ventilating face mask. The present invention is affixed to the respiratory-device for implementation. The LMA maintains an open airway for a plurality of airway procedures: to provide oxygen, to administer anesthesia, or to receive an endoscope. The LMA is positioned through the patient's trachea and adjacent to the patient's glottis to form a hermetic seal around the perimeter of the trachea to provide a channel for air and anesthesia to be introduced to sustain or sedate the patient. The ventilating face mask creates a seal around the patient's mouth and nose, such that tracheal intubation is not needed to channel air and/or anesthesia to sustain or sedate the patient, respectively. The present invention allows for medical devices, such as an endoscope to be inserted, interchanged, or removed quickly through an exposed end of the LMA or an adapter cuff of the ventilating face mask.

[0016] In accordance to FIG. 1, the present invention comprises an airway tube 1, an oxygen port 2, a carbon dioxide outlet 3, a grasping flange 5, an implement port 4, a mounting flange 6, an adapter plug 7, and an adapter mounting tube 8. The airway tube 1 is a channel that allows for oxygen and carbon dioxide to flow into and out from the patient as well as for the insertion of medical devices, such as an endoscope. The oxygen port 2 is coupled with an external oxygen source to allow oxygen to be introduced to the patient's body and sustain the patient. The oxygen port 2 is laterally connected to the airway tube 1, shown in FIG. 6 and FIG. 7. The oxygen port 2 is in fluid communication with the airway tube 1 to allow oxygen to flow through the oxygen port 2 into the airway tube 1, detailed in FIG. 8. The carbon dioxide outlet 3 allows for the removal of carbon dioxide generated from the patient's respiration. The carbon dioxide outlet 3 is laterally connected to the airway tube 1, detailed in FIG. 6 and FIG. 7. The carbon dioxide outlet 3 is in fluid communication with the airway tube 1 to allow carbon dioxide to be removed as the patient respires, in accordance to FIG. 8. The oxygen port 2 is preferred to be diametrically opposite the carbon dioxide outlet 3 about the airway tube 1 in order to prevent a hose connected to the oxygen port 2 from interfering with connecting another hose to the carbon dioxide outlet 3. The grasping flange 5 provides a hand hold for the user to manipulate the present invention onto the respiratory-device or to remove the present invention from the respiratory-device. The grasping flange 5 is perimetrically and terminally connected to the airway tube 1, detailed in FIG. 1 to FIG. 3 and FIG. 6 to FIG. 8. The implement port 4 is an opening that allows for the insertion, manipulation and removal of medical implements through the respiratory-device. The implement port 4 is centrally connected to the grasping flange 5, shown in FIG. 4. The implement port 4 is oppositely positioned to the airway tube 1 about the grasping flange 5, in accordance to FIG. 2, FIG. 3, and FIG. 6 to FIG. 8. The implement port 4 is in fluid communication with the airway tube 1, detailed in FIG. 8. The user is able to hold the grasping flange 5 in order to press the adapter plug 7 into the implement port 4, such that the adapter plug 7 restricts fluid flow through the implement port 4.

[0017] The mounting flange 6 and the adapter mounting tube 8 secure the present invention onto the respiratory-device. The mounting flange 6 is laterally and perimetrically connected to the airway tube 1, shown in FIG. 1. In accordance to FIG. 6 to FIG. 8, the oxygen port 2 and the carbon dioxide outlet 3 are positioned between the grasping flange 5 and the mounting flange 6 such that the oxygen port 2 and the carbon dioxide outlet 3, as well as the respective connected hoses, do not interfere with connecting the present invention with the respiratory-device or each other. The mounting flange 6 allows the adapter mounting tube 8 to be offset from the airway tube 1 to delineate a channel within which the respiratory-device is positioned in order to secure the present invention onto the respiratory-device. The adapter mounting tube 8 is adjacently connected to the mounting flange 6. The airway tube 1 is concentrically positioned within the adapter mounting tube 8. The adapter mounting tube 8 is oriented away from the oxygen port 2 and the carbon dioxide outlet 3. The airway tube 1, the mounting flange 6, and the adapter mounting tube 8 delineate a respiratory-device receiving channel 11, as the mounting flange 6 offsets the adapter mounting tube 8 from the airway tube 1, in accordance to FIG. 5 and FIG. 8. The respiratory-device is pushed into the respiratory-device receiving channel 11 in order to secure the present invention onto the respiratory-device. The adapter plug 7 seals the implement port 4 to prevent fluid flow through the implement port 4. The adapter plug 7 selectively engages the implement port 4.

[0018] Further in accordance to FIG. 1, the adapter plug 7 comprises a plug-mounting extrusion 12, a plug flange 13, an adapter orifice 14, and an implement-receiving channel 15. The plug-mounting extrusion 12 is centrally and normally connected to the plug flange 13. The plug-mounting extrusion 12 selectively engages the implement port 4 in order to seal the implement port 4 to prevent fluid flow to and from the airway tube 1 through the implement port 4. The adapter orifice 14 allows for implements with a smaller diameter than the diameter of the implement port 4 to be utilized by the user. The adapter orifice 14 traverses through the plug flange 13, shown in FIG. 3 and FIG. 8. The plug flange 13 presses against the implement that traverses through the adapter orifice 14 to seal the airway tube 1 from the atmosphere through the adapter orifice 14. The adapter orifice 14 is concentrically positioned with the plug-mounting extrusion 12. The implement-receiving channel 15 allows the adapter plug 7 to laterally engage an elongated implement such that the user is able to position the adapter plug 7 anywhere along the elongated implement. The implement-receiving channel 15 radially traverses through the plug flange 13, the plug-mounting extrusion 12, and into the adapter orifice 14, detailed in FIG. 1 and FIG. 3. Thus, the user is able to press the elongated implement through the implement-receiving channel 15, in order to position the elongated implement within the adapter orifice 14.

[0019] In accordance to the preferred embodiment, the adapter plug 7 further comprises an orifice plug 16, shown in FIG. 1. The orifice plug 16 allows the user to seal the adapter orifice 14 when an implement is not positioned through the adapter orifice 14. The orifice plug 16 is laterally mounted to the plug flange 13, such that the orifice plug 16 does not interfere with positioning the implement within the adapter orifice 14, detailed in FIG. 1, FIG. 6, and FIG. 7. The orifice plug 16 selectively engages the adapter orifice 14 to seal the adapter orifice 14 when the implement is not positioned within the adapter orifice 14.

[0020] Further in accordance to the preferred embodiment, the present invention comprises a plurality of tactile grooves 9, detailed in FIG. 1 and FIG. 8. The plurality of tactile grooves 9 improves the grip that the user has on the plug flange 13 when manipulating the adapter plug 7 onto or out from the implement port 4. The plurality of tactile grooves 9 traverses into the plug flange 13 in order to improve traction between the user's hand and the plug flange 13. The plurality of tactile grooves 9 is radially offset from the adapter orifice 14. Additionally, each tactile groove is radially offset from another. This configuration allows the plurality of tactile grooves 9 to effectively improve the user's grip radially across the plug flange 13.

[0021] In some embodiments of the present invention, the present invention further comprises a pair of tube mounting extrusions 10, shown in FIG. 3 and FIG. 5. The pair of tube mounting extrusions 10 assists in securing a carbon dioxide transfer hose onto the carbon dioxide outlet 3. The pair of tube mounting extrusions 10 is laterally connected to the carbon dioxide outlet 3. The pair of tube mounting extrusions 10 applies pressure to an interior wall of the carbon dioxide transfer hose as the carbon dioxide transfer tube is positioned around the carbon dioxide outlet 3. This pressure seals the carbon dioxide transfer tube against the pair of tube mounting extrusions 10 and the carbon dioxide outlet 3. The pair of tube mounting extrusions 10 is oppositely positioned to the airway tube 1 along the carbon dioxide outlet 3 in order to effectively engage the carbon dioxide transfer tube as the carbon dioxide transfer tube is positioned around the carbon dioxide outlet 3, in accordance to FIG. 6 and FIG. 7.

[0022] Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
