Abstract
A laryngoscope and viewing system configured to provide imaging of a patient's airway passage during intubation is described. In one embodiment, the described device includes a handle; a blade attached to the handle, a flange attached to one side of the blade; a transmission cable connected to the opposite side of the blade; and a camera connected to the transmission cable, wherein the camera is offset from the blade in at least one of the X plane and the Y plane.
Description
- The present invention relates generally to medical devices. In particular, but without limitation, the present invention relates to a laryngoscope and viewing system configured to provide imaging of a patient's airway passage during intubation and similar medical procedures.
- In a process known as “intubation,” an endotracheal tube is inserted into a patient's airway passage to facilitate breathing during certain medical procedures. To avoid damaging the airway passage while inserting the endotracheal tube, medical professionals generally use a laryngoscope to open and view the airway passage and to secure the patient's tongue to one side of the mouth. A typical laryngoscope includes a rigid, curved structure with a smooth tip that engages the tissue of the patient's tongue and airway passage. Laryngoscopes often also include a guide surface for directing the endotracheal tube as it is inserted into the airway passage.
- Even with the use of a laryngoscope, medical professionals often damage a patient's airway passage when inserting the endotracheal tube. The reasons that medical professionals damage the airway passage center is their inability to monitor the laryngoscope and endotracheal tube as it is being inserted. To reduce the risk to patients, several modified laryngoscopes have been made. These laryngoscopes, however, are not completely satisfactory. Certain devices, for example, require two people for proper operation—a first person to insert a fiber optic or camera device into the patient's airway and a second person to operate the laryngoscope and insert the endotracheal tube.
- Other systems include an integrated laryngoscope and imaging device. These systems generally come in two forms: those with integrated viewing devices and those without integrated viewing devices. Laryngoscopes with the integrated viewing device generally include a small screen attached directly to the handle of the laryngoscope. A medical professional can insert the laryngoscope into the patient's airway passage so that the imaging device captures a corresponding image thereof. The medical professional can then view the airway passage and guide the endotracheal tube to its proper location therein. By having the viewing screen attached directly to the laryngoscope, the medical professional is not forced to shift his field of vision away from the patient to monitor the insertion of the tube.
- The laryngoscope with the non-integrated viewing device operates in much the same way as the laryngoscope with the integrated viewing device. The primary difference being that the laryngoscope with the non-integrated viewing device transmits the image of the airway passage to a remote viewing device such as a video monitor. The medical professional can then view the insertion of the endotracheal tube on the remote viewing device.
- Although the laryngoscope with the integrated camera system contains some improvements over the basic laryngoscope, these systems are not always satisfactory. For example, in present systems, the view from the laryngoscope's camera becomes blocked as the endotracheal tube passes the end of the laryngoscope. Unfortunately, when the camera's view is blocked, the health care professional is “blind” and prone to damaging the patient's airway passage. Accordingly, a system and method are needed to address the above-described problems as well as other problems with existing laryngoscope technology.
- Exemplary embodiments of the present invention that are shown in the drawings are summarized below. These and other embodiments are more fully described in the Detailed Description section. It is to be understood, however, that there is no intention to limit the invention to the forms described in this Summary of the Invention or in the Detailed Description. One skilled in the art can recognize that there are numerous modifications, equivalents and alternative constructions that fall within the spirit and scope of the invention as expressed in the claims.
- In one embodiment, the present invention includes a laryngoscope integrated with an imaging device such as a camera. The laryngoscope of this embodiment includes a blade for insertion into the patient's airway passage. This blade can be permanently affixed to a handle or can be removably mounted so that different blades can be connected to the handle. On one side of the blade—generally the left side—is a flange that sits perpendicular to the blade. The blade secures the patient's tongue to one side of the mouth and provides a surface for the endotracheal tube to engage as it is inserted into the airway. For proper perspective, the laryngoscope should be viewed with the handle up, the blade down and away.
- The blade also includes an imaging device that can be connected externally to the blade or integrated into the blade and/or flange. Generally, the imaging device is positioned adjacent to the blade and the left side of the flange. Moreover, the end portion of the imaging device can be partially disengaged from the blade (or flange) to provide a better angle for viewing the patient's airway passage. For example, the image collection point for the imaging device could be offset from the blade in both the X plane and the Y plane. Depending upon the embodiment, the imaging device could be rigid so that the offset is fixed, or the imaging device could be flexible so that the offset is variable.
- In other embodiments, the laryngoscope is equipped with a wireless transmitter for relaying images of the airway passage to a remote viewing device. Alternatively, the imaging device could be attached to the remote viewing device by a traditional wired connection. In yet another embodiment, the viewing device could be directly attached to the handle of the laryngoscope.

FIG. 1 illustrates a system constructed in accordance with the present invention; -
FIG. 2 illustrates one embodiment of a laryngoscope in accordance with the present invention; -
FIG. 3 illustrates an embodiment of a laryngoscope blade in accordance with the present invention; -
FIG. 4 illustrates a side view of an embodiment of a laryngoscope blade and a portion of a handle, both of which are constructed in accordance with the principles of the present invention; and -
FIG. 5 illustrates a laryngoscope with an integrated viewing device in accordance with the principles of the present invention. - Referring to
FIG. 1 , it illustrates asystem 100 constructed in accordance with one embodiment of the present invention. In this embodiment, an optically-enabledlaryngoscope 105A is connected to acamera controller 110 and aremote viewing device 115 such as a TV or video monitor. In operation, the medical professional grasps thehandle 120A of thelaryngoscope 105A and inserts theblade portion 125 into the patient's airway passage. Thecamera 130A that is fixed to theblade 125 can then capture an image of the airway passage and transmit that image to thecamera controller 110 for display at theremote viewing device 115. The medical professional can then use the displayed image to guide an endotracheal tube into the patient's airway passage. - Referring now to
FIG. 2 , it illustrates one embodiment of alaryngoscope 105A in accordance with the principles of the present invention. In this embodiment, aremovable blade 125 is attached to ahandle 120A by thecoupler 135, which provides a reliable connection for connecting the blade-mountedcamera unit 130B with corresponding circuitry (not shown) in thehandle 120A. Although the exemplary embodiments are described with relation to a camera, embodiments of the present invention can include fiber optic bundles (which transmit images back to a camera mounted near the handle-end of the blade or in the handle), endoscope, or any other imaging device. Thecamera unit 130B, in one embodiment, can include acamera 140, aconnection mechanism 145, and a light (not shown). Thecamera portion 140 of the camera unit generally can be any one of the small camera units that are widely available. Moreover, thecamera unit 130B could be either a fixed-focus or a variable-focus unit, a straight lens unit, or an angulated lens unit. Although thecamera unit 130B is shown as secured to the outer edge of theblade 125, portions of thecamera unit 130B can be housed inside theblade 125 or theflange 150 or secured to theflange 150. - In addition to the
camera unit 130B, theblade 125 also includes aflange 150 that is typically arranged perpendicular to the surface of theblade 125. Theflange 150 is used to secure the patient's tongue away from the endotracheal tube. In particular, theflange 150 can be on the left side of the blade (when viewing thelaryngoscope 105A from behind with thehandle 120A pointed up) and thecamera unit 130B on the left side of the flange. Mounting theflange 150 and thecamera unit 130B on same side of theblade 125 can be advantageous because the view provided by thecamera 140 is less obstructed by the insertion of the endotracheal tube than when thecamera 140 is centered on theblade 125 or mounted to the right of center. Thecamera unit 130B could also be formed into the flange or secured adjacent to the right side of the flange. - This embodiment of the
laryngoscope 105A includes a rechargeable power supply (not shown) that can be recharged through the contact points 155 in thehandle 120A. Additionally, this embodiment includes acable 160 for relaying image data to a remote viewing device (not shown). In other embodiments, thecable 160 could be used to transfer power to thecamera unit 130B rather than using a rechargeable power supply. - Although not shown, the
blade 125 can include a channel formed therein. This channel can be an open channel formed in the surface of theblade 125, or the channel can be formed in the body of theblade 125 so that it is enclosed. The channel can be used to provide oxygen to the patient during the intubation process. Alternatively, the channel could be used to provide suction at or near the tip of theblade 125 during the intubation process. - Referring now to
FIG. 3 , it illustrates an embodiment of alaryngoscope 105B in accordance with the principles of the present invention. Thislaryngoscope 105B is wireless-enabled. Thus, images collected by thecamera unit 130C can be wirelessly transmitted through theantenna 165 to a remote viewing device (not shown). - Unlike the
laryngoscope 105A shown inFIG. 2 , thecamera unit 130C inFIG. 3 extends beyond the end of theblade 125 or stop short of the end. In other embodiments, thecamera unit 130C can extend only to the end of theblade 125. Additionally, thecamera unit 130C inFIG. 3 includes an offset in both the X and Y planes where the surface of the blade defines the X plane. Other embodiments, however, can include an offset in either the X or Y plane. The offset, in one embodiment, can vary in either plane from 0.05 to 1.25 inches, including all points in between. Additionally, thecamera unit 130C can include a curvature, T, for better positioning thecamera 140 at the end of thecamera unit 130C. The curvature, T, can be a regular curvature defined by, for example, the arc of a circle, or T can represent an irregular curve. - The
camera unit 130C can be formed of a rigid material to prevent any flexing and subsequent shifting of thecamera 140 and its viewing angle. In other embodiments, however, the camera unit 13C can be formed of a semi-rigid material that permits thecamera unit 130C to be reshaped so that the curvature angle, T, can be changed and/or thecamera 140 relocated in the X and/or Y planes. Additionally, in one embodiment, thecamera unit 130C can be retracted or extended to better position thecamera 140 and its viewing angle. - Referring now to
FIG. 4 , it illustrates a side view of an embodiment of alaryngoscope 105C. In particular, this embodiment illustrates acamera controller 170 that is contained in thehandle 120C of thelaryngoscope 105C and connected to thecamera unit 130D. The camera controller can be used to relay images to a blade-mounted, handle-mounted, or remote viewing device. This particular embodiment includes a fixed-blade rather than a removable blade. - Referring now to
FIG. 5 , it illustrates another embodiment of a laryngoscope in accordance with the principles of the present invention. In this embodiment, a display is connected to thehandle 120 of thelaryngoscope 105D. Images captured by thecamera 140 are transmitted to thecamera driver 175 and relayed to thedisplay driver 180. Thedisplay driver 180 then causes the image to be displayed. Thedisplay 170 and thecamera 140 are powered by therechargeable power supply 185. In another embodiment, the display is secured to the blade rather than to the handle. Moreover, the camera can be replaced with any type of imaging device. - In summary, embodiments of the present invention provide an optically-enabled laryngoscope with an advantageously placed imaging device for viewing a patient's airway passage. Those skilled in the art can readily recognize that numerous variations and substitutions may be made in the invention, its use, and its configuration to achieve substantially the same results as achieved by the embodiments described herein. Accordingly, there is no intention to limit the invention to the disclosed exemplary forms. Many variations, modifications and alternative constructions fall within the scope and spirit of the disclosed invention as expressed in the claims.
