Description

GUI INTERACTIONS FOR A VIDEO LARYNGOSCOPECROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of U.S. Provisional Patent Application Serial No. 63 / 625,550, filed January 26, 2024, the entire content of which is incorporated herein by reference.INTRODUCTION

[0002] Laryngoscopes are commonly used during intubation of a patient (e.g., an insertion of an endotracheal tube into a trachea of the patient). In video laryngoscopy, a medical professional (e.g., a doctor, therapist, nurse, clinician, or other practitioner) views a real-time video feed, captured via a camera of the video laryngoscope, of the patient’ s larynx on a display screen to facilitate navigation and insertion of tracheal tubes within the airway.

[0003] It is with respect to this general technical environment that aspects of the present technology disclosed herein have been contemplated. Furthermore, although a general environment is discussed, it should be understood that the examples described herein should not be limited to the general environment identified herein.SUMMARY

[0004] Certain embodiments commensurate in scope with the originally claimed subject matter are summarized below. These embodiments are not intended to limit the scope of the disclosure . Indeed, the present disclosure may encompass a variety of forms that may be similar to or different from the embodiments set forth below.

[0005] Among other things, aspects of the present disclosure include systems and methods for interacting with a graphical user interface (GUI) of a video laryngoscope. In an aspect, a method performed by a video laryngoscope is disclosed. The method includes acquiring images using a camera of the video laryngoscope; and displaying the acquired images at a display screen of the video laryngoscope. Additionally, the method includes displaying a first set of indicators associated with functionality of the video laryngoscope, wherein each indicator of the first set of indicators is positioned along a bottom edge of the display screen, is partially transparent, and overlays a portion of the displayed acquired images. The method also includes receiving a menu touch interaction to view a menu of the video laryngoscope, wherein the menu touch interaction is received in the bottom fourth of the display screen of the video laryngoscope. In response to receiving the menu touch interaction, the method includesdisplaying a menu overlaying the acquired images, wherein the menu is confined to the bottom fourth of the display screen and wherein the menu includes a still-shot image icon. Further, the method includes receiving an image capture interaction with the still-shot image icon. In response to receiving the image capture interaction, the method includes capturing a set of stillshot images of the currently displayed acquired images; and storing the set of captured images in a memory of the video laryngoscope. The method also includes hiding the displayed menu. With the menu hidden, the method includes displaying a second set of indicators, different from the first set of indicators, wherein the second set of indicators includes a still-shot image count indicating a quantity of still-shot images captured in the set of captured images. Further, the method includes automatically uploading the set of captured images to a device wirelessly connected to the video laryngoscope.

[0006] In an example, the menu touch interaction is a swipe up or a swipe from left to right. In another example, in response to receiving the image capture interaction, the method includes displaying a flash animation. In a further example, a background of the menu is partially transparent. In yet another example, in response to receiving the image capture interaction, the method includes displaying the still-shot image count at the still-shot image icon. In still a further example, the method includes detecting a low battery state of the video laryngoscope; and in response to detecting the low battery state, deactivating touch-screen interactivity.

[0007] In another aspect, a video laryngoscope system is disclosed. The video laryngoscope system includes a device having wireless communication capability; and a video laryngoscope wireless connected to the device. The video laryngoscope includes an integrated display; a camera that acquires images while the video laryngoscope is powered on; and a processor. The processor operates to display the acquired images at the integrated display of the video laryngoscope at a startup time when the video laryngoscope powers on. The processor also operates to display, overlaying the acquired images along a bottom edge of the integrated display, a connection status indicator and a battery life indicator. Additionally, the processor operates to receive a menu touch interaction. In response to receiving the menu touch interaction, the processor operates to display a menu in the bottom fourth of the integrated display overlaying the acquired images. The processor further operates to receive an input, in the menu, to turn on a video-saving feature. In response to receiving the input, the processor operates to capture a video image of the acquired images beginning from the startup time and automatically upload the captured video to the device.

[0008] In an example, the processor further operates to: automatically hide the menu after a menu timeout period; and while the menu is hidden and after the input is received, display avideo-saving icon in proximity to the connection status icon. In another example, the input to turn on the video-saving feature is received as a touch interaction at a toggle indicator in the menu. In a further example, the toggle changes color between an on position and an off position. In yet another example, the processor further operates to: receive an image capture interaction with a still-shot image icon in the menu; and in response to receiving the menu touch interaction, capture a still-shot image of the acquired images, wherein the captured stillshot image is automatically uploaded to the device.

[0009] In another aspect, a method, performed by a video laryngoscope, for transferring fdes from the video laryngoscope is disclosed. The method includes acquiring images using a camera of the video laryngoscope. The method also includes storing a set of media fdes in a memory of the video laryngoscope, wherein the set of media fdes includes at least one of: a still-shot image of the acquired images or a video image of the acquired images. Additionally, the method includes displaying, in a media list, the set of media fdes on an integrated display of the video laryngoscope. The method further includes receiving a selection of at least one media fde in the media list. The method includes receiving a transfer input to transfer the at least one selected media fde. The method also includes displaying a device list of a set of devices connected to the video laryngoscope.

[0025] As discussed briefly above, video laryngoscopes are commonly used during intubation of a patient (e.g., an insertion of an endotracheal tube into a trachea of the patient). During intubation, the patient’s airway and larynx may be visualized by a medical professional (e.g., a doctor, therapist, nurse, clinician, or other practitioner), such as via video laryngoscopy. In video laryngoscopy, the medical professional may view a real-time video feed of the patient’s larynx, other patient anatomy, or other objects or structures in the upper airway of the patient, as captured via a camera of the video laryngoscope and displayed on a display screen of the video laryngoscope. The video feed may assist a medical professional to visualize the patient’s airway and facilitate manipulation and insertion of a tracheal tube.

[0026] When operating a video laryngoscope having a variety of features and settings, a medical professional may benefit from a user interface with self-explanatory indicators that are ergonomically positioned. Provided herein are examples of graphical user interfaces of a video laryngoscope to increase ease of use.

[0027] FIG. 1 shows an example patient environment 100 including a video laryngoscope 102. The patient environment 100 may be any room where an intubation is being performed, such as a medical suite in a hospital or other care setting, an operating or other procedure room, patient recovery room, an emergency intubation setting, or other environments. As described herein, the video laryngoscope 102 may be used for airway visualization of a patient 101 and / or visualization of an intubation tool 150 (e.g., an introducer, a tracheal tube or bougie, and / or an endotracheal tube, etc.) positioned inside the airway 140 of the patient 101. The intubation tool 150 may be positioned in the airway 140 of the patient 101 concurrently with a portion of a blade of the video laryngoscope 102. Aspects of the video laryngoscope 102 are further shown in FIGS. 2-3.

[0028] A medical professional 130 may hold a video laryngoscope 102 in a first hand 132 (e.g., a left hand 132 of the medical professional 130) and an intubation tool 150 (e.g., introducer 150) in a second hand 134 (e.g., a right hand 134 of the medical professional 130). As further described herein, the video laryngoscope 102 may be positioned in the airway 140 of the patient 101 to manipulate and / or visualize the patient’s airway 140, such as with an arm 114 or blade 118 (shown in FIG. 2). Visualization of the airway 140 of the patient 101 may include viewing patient’s anatomy (e.g., larynx, trachea, esophagus, vocal cords, etc.) with a camera 116 of the video laryngoscope 102. The medical professional 130 may move the introducer 150 proximally (e.g., retract the introducer 150) or distally (e.g., advance theintroducer 150), while watching the resulting images from the camera 116 of the video laryngoscope 102 on the display 108 of the video laryngoscope 102.

[0029] Acquired images (video images and / or still-shot images) may be acquired by the video laryngoscope 102 during operation by a medical professional. The acquired images may be displayed at an integrated display screen (e.g., display screen 108) ofthe video laryngoscope 102 in the line of sight of the operator (e.g., medical professional 130). The acquired images may be stored in a memory ofthe video laryngoscope 102. In some examples, the stored images may be reviewed or replayed on the display screen of the video laryngoscope 102 itself. In other examples, stored acquired images may be transferred to, or communicated to, a remote device / system (e.g., a computer). The stored images may be reviewed, edited, or otherwise interacted with at the remote device.

[0030] The video laryngoscope 102 may be configured to communicate with one or more remote devices or systems via any of a variety of techniques. Communication between the video laryngoscope 102 and a remote device / system may be facilitated by one or more communication devices (e.g., wireless transceivers or hubs, which may be a wireless adapter, dongle, bridge device, etc.) that are configured to establish wireless communication with one another using any suitable protocol. In an example, an adapter may be coupled to a remote device (e.g., by plugging the wireless adapter into a Universal Serial Bus (USB) port) to relay information or commands between the video laryngoscope 102 and the remote device. The wireless adapter may be movable between multiple remote devices / systems. In another example, communication between the laryngoscope and a remote device may use wireless hubs. Any other form of communication between the video laryngoscope 102 and a remote device to transfer media or information is contemplated, such as wired or wireless transceivers. The video laryngoscope 102 and / or remote devices / systems may include ports (e.g., USB ports, Ethernet ports, high-definition multimedia interface (HDMI) ports, optical ports, infrared ports, near field ports, or the like) that enable a wired connection.

[0031] FIG. 2 shows a schematic of a video laryngoscope 102. As shown, the video laryngoscope 102 has a body 104 (e.g., reusable body). The body 104 includes a display portion 106 having a display screen 108 that is configured to display images and / or other data, a handle portion 110 having a handle 112 that is configured to be gripped by the medical professional during the laryngoscopy procedure, and an elongate portion or arm 114 that supports a camera 116 and light source (e.g., light-emitting diodes (EEDs)) that is configured to obtain images, which may be still-shot images and / or moving images (e.g., a video feed). The camera 116 and light source may be incorporated on the distal end of the arm 114. The light source may beprovided as part of the camera 116 or separate from the camera 116 on the blade 118 or arm 114.

[0032] In examples, the display portion 106 and the handle portion 110 may not be distinct portions, such that the display screen 108 is integrated into the handle portion 110. In the illustrated embodiment, an activating cover, such as a removable laryngoscope blade 118 (e.g., activating blade, disposable cover, sleeve, or blade), is positioned about the arm 114 of the body 104 of the laryngoscope 102. Together, the arm 114 of the body 104 and the blade 118 form an insertable assembly that is configured to be inserted into the patient's oral cavity. It should be appreciated that the display portion 106, the handle portion 110, and / or the arm 114 that form the body 104 of the laryngoscope 102 may be fixed to one another or integrally formed with one another (e.g., not intended to be separated by the medical professional during routine use) or may be removably coupled to one another (e.g., intended to be separated by the medical professional during routine use) to facilitate storage, use, inspection, maintenance, repair, cleaning, replacement, or interchangeable parts (e.g., use of different arms or extensions with one handle portion 110), for example.

[0033] The handle 112, arm 114, and / or display portion 106 may include one or more sensors 122 capable of monitoring functions (e.g., different, additional, and / or advanced monitoring functions). The sensors 122 may include a torque sensor, force sensor, strain gauge, accelerometer, gyroscope, magnet, magnetometer, proximity sensor, reed switch, Hall effect sensor, infrared sensor, wireless connectivity sensor, etc. disposed within or coupled to any suitable location of the laryngoscope 102. The sensors 122 may detect interaction of the video laryngoscope 102 with other objects, such as a blade 118, physiological structures of the patient (e.g., teeth, tissue, muscle, etc.), or proximity of an introducer (e.g., introducer 150).

[0034] The laryngoscope 102 may also include a power button 120 that enables a medical professional to power the laryngoscope 102 off and on. In examples, the laryngoscope 102 may be powered by a power source (e.g., battery) that is coupled to the laryngoscope 102. The power source may be removably coupled to the laryngoscope 102. In an instance where the power source is removably couplable to the laryngoscope 102, the power button 120 may be positioned on the removable power source, instead of on the laryngoscope 102 itself. The power button 120 may also be used as an input device to access settings of the video laryngoscope 102, including a mode of operation (e.g., routine operation, settings, etc.). Additionally, the video laryngoscope 102 may include an input button, such as a touch or proximity sensor 124 (e.g., capacitive sensor, proximity sensor, or the like) that is configured to detect a touch or object (e.g., a finger or stylus). The touch sensor 124 may enable the medical professionaloperating the video laryngoscope 102 to efficiently provide inputs or commands, such as inputs that cause the camera 116 to obtain or store an image on a memory of the laryngoscope and / or any other inputs relating to function of the video laryngoscope 102.

[0035] FIG. 3 is a block diagram of components of the video laryngoscope 102 and a remote device or system 151. As shown, the video laryngoscope 102 and / or the remote device 151 may include various components that enable the video laryngoscope 102 to carry out the techniques disclosed herein. For example, the video laryngoscope 102 may include the display screen 108, the camera 116, a light source (e.g., which may integrated into the camera or separate from the camera), sensor(s) 122, and input (e.g., touch sensor) 124, as well as a controller 160 (e.g., electronic controller), one or more processors 162, a hardware memory 164, a power source 166 (e.g., battery, which may be removably couplable with the laryngoscope 102), input / output (I / O) ports 168, a communication device 170, and atimer 172. In some embodiments, the timer 172 may track relative time (e.g., a start time, an end time, a frequency of image frame sampling), which may be referenced to acquire still-shot input images for analysis.

[0036] The remote device 151 may include a controller 174 (e.g., electronic controller), one or more processors 176, a hardware memory 178, I / O ports 182, and a communication device 184. As described above, the video laryngoscope 102 may transmit images (e.g., video images and / or still-shot images, etc.) to the remote device 151 via I / O ports 182 and / or communication devices 170, 184. The communication device 170 of the video laryngoscope 102 may communicatively couple with the communication device 184 of the remote device 151 to allow communication between the video laryngoscope 102 and the remote device / system 151 (e.g., sending or receiving signal between the devices). The communication devices 170, 184 may enable wired or wireless communication. Wireless communication may include transceivers, adaptors, and / or wireless hubs that are configured to establish and / or facilitate wireless communication with one another. By way of example, the communication devices 170, 184 may be configured to communicate using the IEEE 802.15.4 standard, and may communicate, for example, using ZigBee, WirelessHART, or MiWi protocols. Additionally or alternatively, the communication devices 170, 184 may be configured to communicate using the Bluetooth standard or one or more of the IEEE 802.11 standards.

[0037] The processors 162, 176 may include multiple microprocessors, one or more “general-purpose” microprocessors, one or more special-purpose microprocessors, and / or one or more application specific integrated circuits (ASICS), or some combination thereof. For example, the processors 162, 176 may include one or more reduced instruction set (RISC)processors. It should be appreciated that the various processing steps may be carried out by either processor 162, 176 or may be distributed between the processors 162, 176 in any suitable manner.

[0038] The hardware memory 164, 178 may include a volatile memory, such as random access memory (RAM), and / or a nonvolatile memory, such as read-only memory (ROM). It should be appreciated that the hardware memory 164, 178 may include flash memory, a hard drive, or any other suitable optical, magnetic, or solid-state storage medium, other hardware memory, or a combination thereof. The memory 164, 178 may store a variety of information and may be used for various purposes. For example, the memory 164, 178 may store processorexecutable instructions (e.g., firmware or software) for the processors 162, 176 to execute, such as instructions for processing signals generated by the camera 116 to generate the image, provide the image on the display screen 108, etc. The hardware memory 164, 178 may store data (e.g., acquired images, tags, or labels, etc.), instructions (e.g., software or firmware for generating images, storing the images, analyzing the images, etc.), and any other suitable data.

[0039] FIGS. 4-14D show example display screens of a video laryngoscope 102 (e.g., display screens 108 ofvideo laryngoscope 102). As described herein, a camera 116 ofthe video laryngoscope 102 may acquire images in line of sights of the camera (e.g., images of a medical room before and after an intubation, a patient’s upper airway anatomy during intubation, etc.). The images from the acquired view are displayed on a display 108 of the video laryngoscope 102.

[0040] In FIGS. 4-7, example display screens 400 of a video laryngoscope are shown during routine operation (e.g., leading up to, during, and after an intubation of a patient by a medical professional). FIG. 4 shows example display screens of a video laryngoscope during routine operation prior to intubation. FIG. 5 shows example display screens of a video laryngoscope during routine operation, including during and after an intubation in which no images are captured by the medical professional operating the video laryngoscope. As an alternative to FIG. 5, FIGS. 6-7 show example display screens of a video laryngoscope during routine operation, including during and after an intubation in which images are captured and stored by the medical professional operating the video laryngoscope.

[0041] Referencing the example display screens 400 of FIG. 4, power-off display 402 does not have any data displayed (e.g., the display screen is off) when the video laryngoscope 102 is powered off. When the video laryngoscope 102 is initially powered on (e.g., via a single push of a power button with a battery coupled to the video laryngoscope 102), a first start-up display 404 populates the display screen. The first start-up display 404 may include a camerafeed (e.g., as acquired by a camera of the video laryngoscope 102). The first start-up display404 may display only the camera feed, without any additional icons or information displayed. The first start-up display 404 may be displayed temporarily, during an initial startup period of the video laryngoscope 102. After an initial start-up period, a second start-up display 406 may be shown. The second start-up display 406 may include information or icons in addition to the camera feed shown in the first start-up display 404.

[0042] Additional icons may include information associated with battery life, connection status, video recording, number of images captured, available menus, and / or any other indication of functionality, settings, or stored information on the video laryngoscope. For example, as shown in the second boot-up display 406 of FIG. 4, a connection status indicator405 and a battery life indicator 407 are shown. Although not shown in every display depicted in FIGS. 4-14D and 16, any or all icons may be included on one or more of the displays described herein.

[0043] The connection status indicator 405 indicates a connection status (e.g., connected or not connected) of the video laryngoscope 102 with transceivers, adaptors, and / or wireless hubs via a wireless connection (e.g., connection to a wireless hub, wireless module, and / or relay, as described herein). The connection status indicator 405 may have a different transparency level depending on the connection status. For example, in the second start-up display 406, the video laryngoscope 102 is not wirelessly connected to an external device, and the connection status indicator 405 has a high transparency (e.g., lower visibility). After the video laryngoscope 102 establishes a wireless connection (e.g., with at least one wireless hub, wireless module, and / or relay), the connection status indicator 405 has a low transparency (e.g., higher visibility), as shown in a third start-up display 408. A high transparency of the connection status indicator 405 may be 50-100% transparent. A non- 100%, high transparency (e.g., not completely transparent) of the connection status indicator 405 informs an operator of the video laryngoscope 102 that the video laryngoscope 102 has connection capability, but is not currently connected. Alternatively, a low transparency of the connection status indicator 405 may be 0-50% transparent. A non-zero percent, low transparency (e.g., still partially transparent) of the connection status indicator 405 informs the operator of the video laryngoscope 102 that the video laryngoscope 102 has connection capability and is currently connected, without completely obscuring a portion of the camera feed covered by the connection status indicator 405. In other examples, other display formats other than (or in addition to) transparency may be used to distinguish and convey connection status details. For instance, when the video laryngoscope 102 is not connected, the connection status indicator405 is displayed in a first display format, and when the video laryngoscope is connected, the connection status indicator 405 is displayed in a second display format that is more prominent or visible than the first display format.

[0044] The battery life indicator 407 may include a shape and / or outline associated with a battery containing a battery life number. The battery life number may be a one-digit, two-digit, or three-digit number. The size of the number and / or the size of the shape and / or outline may change to accommodate the amount of digits in the battery life number. For example, the size of the shape / outline of the battery life indicator 407 may remain unchanged and a font size of a three-digit number may be smaller than the font size of a two-digit number to fit within the shape / outline of the battery life indicator 407. In another example, the size of the shape / outline of the battery life indicator 407 may be larger (e.g., wider) for a three-digit number than for a two-digit or one-digit number. The battery life number may indicate a quantity of operational minutes remaining for the battery of the video laryngoscope 102 or another quantifiable battery life indicator, such as a percentage of battery life remaining, an estimated number of intubation procedure attempts remaining (e.g., based on a maximum, minimum, average, or estimated intubation duration), or any other indication of battery life remaining. The battery life indicator 407 informs an operator about remaining battery life so that an operator may determine if there is sufficient remaining power in the battery prior to starting a clinical procedure. The battery life indicator 407 may be positioned in the bottom right comer of the display screen. All or a portion of the battery life indicator 407 may be partially transparent so as to not completely obscure a portion of the camera feed covered by the battery life indicator 407.

[0045] Indicators / icons may be positioned along a bottom edge of the display screen of the video laryngoscope 102. Confining the indicators / icons to a bottom portion of the screen reduces camera feed obstruction from the indicators / icons, reduces distraction of the icons to an operator of the video laryngoscope 102, and allows the indicators / icons to be more easily reachable by an operator of the video laryngoscope 102 using a digit (e.g., thumb) of a hand grasping the handle. For instance, as the clinician holds the handle of the video laryngoscope 102 during an intubation procedure, the clinician can reach the bottom of the screen with their thumb of the same hand that is holding the video laryngoscope 102. To further reduce camera feed obstruction, some or all of the indicators / icons may be partially transparent. Some indicators / icons may be displayed continuously after start-up, such as a battery life indicator. Other indicators and / or icons not shown in FIG. 4, as well as functionality and positioning of such other indicators and / or icons, are further described herein.

[0046] To conserve power, regardless of display screen shown, the video laryngoscope 102 may automatically power down when motionless for an inactivity period (e.g., 2, 3, 4, or more minutes). Prior to automatically powering down, after a preliminary inactivity period (e.g., 10- 30 seconds), the display screen of the video laryngoscope 102 may dim (or be inactivated) until movement or touch is received). Additionally, after the preliminary inactivity period, recording and / or streaming features of the video laryngoscope 102 may pause. Paused functionality may reactivate or resume when movement of the video laryngoscope 102 is detected, and / or if any other input or action is detected at the video laryngoscope 102. If the video laryngoscope 102 automatically powers down, the video laryngoscope 102 may be powered on by a push of the power button.

[0047] After the start-up process is complete (e.g., after third start-up display 408), an operator of the video laryngoscope 102 may proceed to routine use (e.g., intubation of a patient). In some examples, an operator may proceed to routine use prior to a change in connectivity status (e.g., from second start-up display 406). The video laryngoscope 102 may connect at a later time to transfer files or stream data (e.g., as further described in FIGS. 16A- 16C), or may never connect (e.g., in situations where no transfer or streaming is desired, such as when no video or still-shot images are captured during use, as shown in FIG. 5).

[0048] During startup, such as at the second start-up display 406, at the third start-up display 408, or after the third start-up display 408, a menu indicator (not shown in FIG. 4) may be displayed. The menu indicator may inform an operator that a menu is hidden and available for viewing. Menu indicators may be symbols (e.g., the menu indicator 409 shown in FIG. 5), shading gradients (e.g., the menu indicator 411 shown in FIG. 6), text, or any other indicator to inform an operator that a menu is available.

[0049] FIG. 5 shows example display screens of a video laryngoscope during routine operation, including during and after an intubation in which no videos or images are captured by the medical professional operating the video laryngoscope. At intubation display 410, the camera feed is acquiring and displaying a patient’s upper airway during an intubation procedure with the video laryngoscope 102. The connection status indicator 405 and the battery life indicator 407 are displayed along with a menu indicator 409. Although the menu indicator 409 in FIG. 5 is shown as a shading gradient with increasing darkness towards the bottom edge of the display screen, other symbols or indicators may also be used to provide an indication of an available menu (e.g., a caret wrapped in a shaded half-circle in the middle, bottom of the display screen; a line or bubble in the middle, bottom of the display screen, or other shapes or shading near the bottom of the display screen, etc.). Other positions along the bottom edge of the screenmay also be used for the menu indicator 409. In this example routine operation shown in FIG. 5, the operator of the video laryngoscope 102 does not interact with the menu (e.g., associated with the menu indicator 409) and does not actively record video or still-shot images during the intubation. The indicators / icons remain unchanged during this routine use. Post-intubation display 412 shows a camera feed of the room after intubation has been completed. A shut-down display 414 may be shown during a shutdown time when the video laryngoscope 102 is shutting down. The video laryngoscope 102 may shut down manually after a press of the power button is received or may shut down automatically if the video laryngoscope 102 is motionless and / or inactive (e.g., no inputs received) for a period of time (e.g., 2 minutes, 2.5 minutes, 3 minutes, 4 minutes, 5 or more minutes, etc.). A progress bar or progress loop may be displayed over the course of the shutdown time. After the shutdown time, the video laryngoscope 102 is powered down, the display 416 turns off.

[0050] As an alternative to FIG. 5, FIGS. 6A and FIG. 7, and FIGS. 6B-6C show example display screens of a video laryngoscope during routine operation in which video is recorded and images are captured and stored by the medical professional operating the video laryngoscope. FIGS. 6B-6C show example display screens as an alternative to FIG. 6A (e.g., initial intubation display 418 shown in FIG. 6A and initial intubation display 428 shown in FIG. 6B may each flow from third start-up display 408 shown in FIG. 4). Regarding FIG. 6A- 6C, at initial intubation displays 418, 428, the camera feed is acquiring and displaying a patient’s upper airway at a beginning of an intubation procedure with the video laryngoscope 102. The connection status indicator 405 and the battery life indicator 407 are displayed along with a menu indicator 411. Although the menu indicator 411 shown in FIGS. 6A-6C is shown as a line near the bottom edge of the display screen, other indicators, shading, and / or shapes along any portion of the bottom edge of the screen may also be implemented.

[0051] At initial menu displays 420, 430, a menu 413 is displayed in a bottom portion of the display screen. The menu 413 may be displayed after an interaction with a bottom portion of the display screen and / or the menu indicator 411 is received from the clinician. In examples, an interaction to prompt an opening of the menu 413 may be a swipe up from or near (e.g., within a border of) the bottom edge of the display screen, a swipe from left to right from or near (e.g., within a border of) the left edge of the display screen, a tap or double-tap at or near the bottom edge of the display screen and / or the menu indicator 411, or another gesture near or within a menu region (e.g., a region in the bottom fourth or less of the display screen). The menu may include a background. The background and / or the menu-specific indicators may be partially transparent to not completely obscure the menu region portion of the camera feed.

[0052] Referring to FIG. 6A, the menu 413 may include menu-specific indicators and / or icons, such as a screenshot icon 415A, 415B and a video-saving icon 417A, 417B. In the initial menu display 420, the screenshot icon 415A may show a camera icon or image to inform an operator that a selection of the screenshot icon 415A captures and stores still-shot images. As shown in menu display 422, after one or more user interactions with the screenshot icon 415A, the screenshot icon 415B may show an image number, indicating a quantity of still-shot images captured during this routine use. In response to a selection of the screenshot icon 415A, 415B, the display screen may show a flash animation effect to indicate that the video laryngoscope 102 received an input to capture a still-shot image.

[0053] Additionally, in the initial menu display 420, the video-saving icon 417A may show a video-file-upload icon to indicate functionality relating to video recording, saving, and / or transfer to a connected device. The video-saving icon 417A may further include a toggle switch with two positions — an “off’ position and an “on” position. In the initial menu display 420, the toggle switch in an “off’ position (which may be the default position upon startup) to inform an operator that video saving and / or upload is currently not enabled. Alternatively, video recording may begin automatically when the video laryngoscope 102 is powered on (e.g., the video-saving icon 417A is defaulted to the “on” position). As shown in menu display 422, after a user interaction with the toggle of the video-saving icon 417A, the video-saving icon 417B toggles to the “on” position, indicating that video-saving and / or upload is currently enabled. When toggled to the “on” position, the toggle of the video-saving icon 417B may change in transparency, color, and / or other display format (e.g., the toggle may change from black or gray to blue or other bright color). The toggle of the video-saving icon 417A, 417B may be toggled on or off via a slide or atap. The video-saving icon 417A, 417B may be toggled on at any time during a use session (e.g., from the time the video laryngoscope 102 is powered on until any time prior to the video laryngoscope 102 is powered off) to save and / or store a video image of the entire use session (e.g., from the time the video laryngoscope 102 is powered on, regardless of when the video-saving icon 417A, 417B is toggled “on,” until the video laryngoscope 102 is powered off or until the video-saving icon 417A, 417B is toggled “off’). The video laryngoscope automatically (e.g., without user interaction) stops recording when the video laryngoscope powers off.

[0054] Referring to FIGS. 6B-6C, the menu 413 may include menu-specific indicators and / or icons, such as a screenshot icon 415C-415E and a video-saving icon 417C-417F. In the initial menu display 430, the screenshot icon 415 C may show a camera icon or image to inform an operator that a selection of the screenshot icon 415C captures and stores still-shot images.As shown in menu display 432, during a user interaction with the screenshot icon 415D and / or in response to a selection of the screenshot icon 415C, the menu display 432 may darken the camera feed temporarily to result in a flash animation effect, indicating that a still-shot image was captured. During the flash animation effect, the screenshot icon 415D may be highlighted, lightened, or otherwise changed in color or appearance to indicate a user selection and / or received input. As shown in menu display 434, after one or more user interactions with the screenshot icon 415C, the screenshot icon 415E may show an image number, indicating a quantity of still-shot images captured during this routine use and / or a portion of the screenshot icon 415E may change in color or appearance (e.g., a portion within a camera symbol showing the image number may be changed in appearance, without changing the appearance of the portion of the screenshot icon 415E outside of the camera symbol). If the menu 413 is closed after interacting with the screenshot icon 415C-415E and without interaction with the videosaving icon 417C-417F, then a still-shot image indicator 419B may be displayed without an upload indicator 42 IB. The still-shot image indicator 419B and upload indicator 42 IB are further described below with respect to intubation displays 424, 446. Flow may continue to intubation display 438 with or without closing the menu after still-shot image capture (e.g., from menu display 434 or intubation display 438).

[0055] At menu display 438, the video-saving icon 417C may show a video camera icon or symbol to indicate functionality relating to video recording or video saving (for later review or transfer to a connected device). The video-saving icon 417C may change in color or appearance to indicate if a video is currently being saved for the current use session (e.g., to inform an operator whether or not video saving is currently enabled). As a default, the videosaving icon 417C-417F may be “on” to automatically record and save video. As shown in menu display 440, after a user interaction with the video-saving icon 417C, the video-saving icon 417D changes in appearance (e.g., is lightened, highlighted, changed in color, etc.) and / or includes a dynamic progress bar, indicating that video-saving is currently enabled. Another interaction with the video-saving icon at menu display 442 may pause recording of the video. In such an instance, video-saving icon 417E may again change in appearance to indicate a video pause with some video already saved (e.g., a portion of the video-saving icon 417E may be lighter / highlighted, such as inside the video camera symbol, with another portion of the video-saving icon 417E not highlighted, such as outside the video camera symbol, and / or the progress bar may be static at the last position which it was dynamically active). Yet another interaction with the video-saving icon 417E, after video has been paused, reactivates the videosaving icon 417F (e.g., changing again in color or appearance and / or restarting the dynamicprogress bar). The video-saving icon 417C-417F may be activated / reactivated and / or paused any number of times and at any time during a use session (e.g., from the time the video laryngoscope 102 is powered on until any time prior to the video laryngoscope 102 is powered off) to save and / or store a video image of the entire use session (e.g., from the time the video laryngoscope 102 is powered on, regardless of when the video-saving icon 417C-417F is interacted, until the video laryngoscope 102 is powered off or until the video-saving icon 417C- 417F is deactivated or turned “off’). The video laryngoscope automatically (e.g., without user interaction) stops recording when the video laryngoscope powers off.

[0056] During a video pause state (e.g., shown in menu display 440 via video-saving icon 417E), the video laryngoscope 102 may continue recording video. If the video laryngoscope 102 powers off during the pause state, any video recorded after the time at which the pause state was activated (e.g., the time at which a selection was received of video-saving icon 417D to transition to video-saving icon 417E) may be deleted. If the video-saving icon 417D, 417F is active (e.g., activated or reactivated) when the video laryngoscope 102 powers down, then video recording from the entire power cycle (e.g., from the time the video laryngoscope 102 is powered on until any time prior to the video laryngoscope 102 is powered off, including during the pause period during which the video laryngoscope 102 was in a pause state as may be indicated by video-saving icon 417E) may be included in the saved video file. When video saving is reactivated (e.g., as shown in menu display 444 and may be indicated by video-saving icon 417F), the progress bar / loop may rapidly and temporarily proceed in a backwards (e.g., counter-clockwise) motion or forwards (e.g., clockwise) motion from the progress bar / loop position associated with reactivation to the progress bar / loop position associated with pause initiation. After the rapid progression of the progress bar / loop to the position associated with pause initiation, the progress bar / loop may continue to slowly progress forward (e.g., clockwise) during active video-saving.

[0057] Referring to both FIG. 6A and FIG. 6C, intubation displays 424, 446 show a camera feed of the patient’s upper airway after the menu 413 is closed. The menu 413 may be closed manually or automatically. To manually close the menu 413, an operator of the video laryngoscope 102 may interact with a bottom portion of the display screen and / or a portion of the menu 413 without an indicator or icon. In examples, an interaction to prompt the menu 413 to close may be a swipe down anywhere on the display screen, a swipe down on or near (e.g., within a border of) the menu 413, a swipe from right to left anywhere on the display screen, a swipe from right to left from or near (e.g., within a border of) the menu 413, a tap or doubletap anywhere on the display screen in a region without an indicator or icon, a tap or double-tapin the menu 413 in a region without an indicator or icon, or any other gesture near or within a menu region (e.g., a region in the bottom fourth or less of the display screen). A menu-close indicator (e.g., a downward caret indicator 423 shown in FIGS. 6B-6C), may visually indicate that the menu may be closed manually. Additionally or alternatively, the menu may automatically close (or may be automatically hidden) after a menu timeout period. The menu timeout period may be a period of time long enough for an operator of the video laryngoscope 102 to observe patient anatomy, make a decision regarding intubation of the patient, and begin to take action. The menu timeout period may be 3, 4, 5, 6, 7, 8, 9, 10 seconds, or any other appropriate time period. Automatic closing of the menu 413 allows an operator to use all digits (e.g., a thumb and all fingers) for intubation (e.g., to manipulate the video laryngoscope 102 by grasping the handle). In this way, the automatic closing of the menu allows an operator to better focus on the intubation, without the menu 413 obscuring the camera feed, presenting indicators and / or icons that may be distracting, and without requiring manual operator input during a time when the operator is focused on intubation.

[0058] As shown in intubation displays 424, 446, after the menu 413 is closed, relevant onscreen indicators / icons are populated along the bottom edge of the display screen. The onscreen indicators / icons that are populated are based on the interactions with the menu items and / or options that were received when the menu 413 was displayed. For example, the upload indicator 42 IB is not shown in menu display 436 of FIG. 6B during menu close because the video-saving icon 417C-417F has not yet been activated at menu display 436. The relevant onscreen indicators / icons are also shown in post-intubation displays 426, 448, after intubation is complete.

[0059] In the current examples, because interactions with the screenshot icon 415 and video-saving icons 417A-417F were received while the menu 413 was displayed, a still-shot image indicator 419A, 419B and an upload indicator 421 A, 42 IB are shown in addition to the connection status indicator 405 and the battery life indicator 407. The still-shot image indicator 419A, 419B further indicates the number of still shots that have been captured. In the examples depicted, the still-shot image indicator 419A, 419B displays the number “2,” indicating that two still-shot images have been captured (e.g., the screenshot icon 415A-415E has been selected or activated twice). The upload indicator 421 A, 42 IB indicates that the video-saving icon 417A-417F has been active (e.g., for FIG. 6A, 417A, 417B has been toggled to the “on” position; for FIGS. 6B-6C, 417C-417F has been selected) to capture and save video to be uploaded to a wirelessly connected device.

[0060] The relevant (e.g., applicable) onscreen indicators / icons may be partially transparent, grouped, and positioned in a way to reduce obstruction of the camera feed and reduce operator distraction. For example, relevant onscreen indicators / icons may be positioned in the left-most, bottom portion of the display screen, other than the battery life indicator 407 (which is positioned in the bottom right). Other positions of grouped indicators / icons may include top comers of the display, vertically along a side of the display adjacent a comer, etc. Selective grouping and positioning of relevant onscreen indicators / icons (e.g., in the bottom left of the display screen), while hiding non-relevant indicators / icons provides organization, reduces distraction to the operator and reduces obscured screen real estate of the camera feed. In an example where no still-shot images are captured, the still-shot image indicator 419A, 419B would be hidden and the upload indicator 421 A, 421 B is positioned leftward, in a position adjacent to the connection status indicator 405 (e.g., at the shown position of the still-shot image indicator 419A, 419B). In an example where the video-saving icon 417A-417F is inactive (e.g., no video captured and / or saved for the current use session), the upload indicator 421 A, 42 IB may be hidden.

[0061] FIG. 7 shows example upload displays for flow from FIG. 6A. Although the displayed indicators / icons match those described in FIG. 6A, similar upload displays are considered for flow from FIG. 6C (e.g., as indicated in FIG. 6C as “TO UPLOAD DISPLAY,” and may include still-shot image indicator 419B and the upload indicator 421B). In FIG. 7, the video laryngoscope 102 attempts to upload stored media. At upload display 450, the stored video and still-shot images, as indicated by the still-shot image indicator 419A and the upload indicator 421 A, begin uploading to external devices (e.g., relays) connected to the video laryngoscope 102. In other examples, the video may have been streamed to the relays during the procedure and such upload may not be necessary if the relay has recorded the stream.

[0062] Uploading may begin automatically or may be initiated by a user interaction with the display screen. As an example, where video-saving icon 417A has been toggled to the “on” position, the upload of the video may occur automatically when a shutdown input is received (e.g., a press of the power button or an auto-shutdown activation). For instance, the upload process may be considered as part of the shutdown process, in some examples. When the upload begins, the upload display 450 is displayed. A progress indicator 429 (e.g., progress bar or progress loop) may be displayed over the course of attempted upload of the stored media files. A file upload indicator, such as an image of a file and / or an upload symbol may be displayed near or inside the progress indicator 429. A file upload quantity may also be indicated in or around the progress indicator 429 (e.g., a bubble indicator with a number shown in uploaddisplay 450 inside the progress indicator 429). Text may also appear on the upload display 450 to indicate upload status (e.g., “Uploading saved media to connected Relays”). If the upload is completed, an upload completed display 452 may be displayed with appropriate text (e.g., “Upload complete”) and upload complete indicator (e.g., a check mark and / or full progress bar or full progress loop and / or quantity of uploaded files).

[0063] A partial upload may also be completed (not shown). In an example with a partial upload (e.g., some files, but not all files, captured during the current use session were uploaded to a relay), at upload completed display 452, the progress indicator 429 may be incomplete (e.g., partial / incomplete progress loop and / or a check mark and / or reduced quantity of uploaded files) and / or accompanying text may indicate partial upload status (e.g., “Partial upload complete”).

[0064] Alternatively, if the upload is incomplete or interrupted (e.g., no files were uploaded to a relay), an upload interrupted display 436 may be displayed that shows appropriate text (e.g., “Upload incomplete”) and an upload incomplete indicator (e.g., a dimmed or partially transparent, static version of the progress bar or progress loop and / or error symbol, such as the exclamation mark shown in displays 458, 460). A shut-down display 454, 460 may show text (e.g., “Shutting down... ”) indicating shutdown when the video laryngoscope 102 is shutting down. The prior indicator for upload complete or upload interrupted may be continued to be displayed at the shut-down display 454, 460. After the shutdown time, the video laryngoscope 102 is powered down and the display 456 turns off.

[0065] FIGS. 8A-8E show example display screens 500A-500E of different relay connectivity. Specifically, FIG. 8 A shows a connected display 502A when the video laryngoscope 102 is, in general, wirelessly connected to a device or system facilitating wireless communication (e.g., a wireless hub, wireless module, and / or relay). FIGS. 8B-8D show connected displays 502B-502D when the video laryngoscope 102 is, respectively, wirelessly connected to one, two, orthree device(s) or system(s) facilitating wireless communication (e.g., a wireless hub, wireless module, and / or relay). FIG. 8E shows a non-connectivity display 502E when the video laryngoscope 102 is not wirelessly connected to a device or system facilitating wireless communication (e.g., a wireless hub, wireless module, and / or relay). When the video laryngoscope 102 is wirelessly connected, a connection status indicator 504A-D may have a low transparency (e.g., be readily seen on the display screen 502A-502D of the video laryngoscope 102). In some instances, a quantity of relays connected to the video laryngoscope 102 may be indicated or displayed. For example, the connection status indicator 504B-504D may include or overlay a pattern (e.g., dots, dashed, lines, ticks, etc.) or numeric indicator (e.g.,number, numeral, etc.) to indicate a quantity of connected relays. For instance, the connection status indictor 504B of FIG. 8B includes one dot, indicating that one relay is connected to the video laryngoscope 102. Similarly, the connection status indictor 504C of FIG. 8C includes two dots, indicating that two relays are connected to the video laryngoscope 102; and the connection status indictor 504D of FIG. 8D includes three dots, indicating that three relays are connected to the video laryngoscope 102.

[0066] Alternatively, when the video laryngoscope 102 is not wirelessly connected (or when wireless connectivity is disabled, such as during a low battery state), such as shown in FIG. 8E, a connection status indicator 504E may change. In examples, the connection status indicator 504E may change in color, transparency, and / or any other change in shape or appearance. For instance, the connection status indicator 504E may have a higher transparency (e.g., 50-100% transparent) when the video laryngoscope 102 is not connected and a lower transparency when the video laryngoscope is connected. Additionally or alternatively, the connection status indicator 504E may flash and / or overlay a slash or an “x” to indicate no connectivity (as shown in FIG. 8E). In some instances the connection status indicator 504 may be hidden when the video laryngoscope 102 is not connected. Alternatively, a connection status indicator 504E with high transparency, but not completely transparent, may inform a user that the video laryngoscope 102 has connection capability, but is not currently connected. In an example, the connection status indicator 504E may flash between high and low transparency when a connection is forming or being established. Although FIGS. 8A-8E show various connection status indicators 504A-504E during intubation of a patient, appearance of any of the connection status indicators 504A-504E may occur in any display screen 500A-500E showing a connection status indicator (e.g., during routine use or in non-operational modes).

[0067] The video laryngoscope 102 may be used for an intubation or laryngoscopy, regardless of an established connection. Media (e.g., video images and / or still-shot images) may be stored and / or saved locally on the video laryngoscope 102. A wireless connection may be obtained at a later time to upload media to another device (e.g., a wireless hub, wireless module, and / or relay). Thus, an operator of the video laryngoscope 102 may proceed with timely treatment of a patient and delay troubleshooting connectivity, as media may be uploaded at a later time. A wireless connection may be established, or reestablished, by powering off the video laryngoscope 102 and / or the connectivity device and then powering back on, repositioning the video laryngoscope 102 and / or the connectivity device within line-of-sight and / or within a specified proximity of each other, relocating or disabling nearby equipmentthat generates infrared wavelengths or radio-frequency (RF) signals, confirming that the video laryngoscope has sufficient battery, and / or connecting to a different connectivity device.

[0068] FIG. 9 shows example display screens 600 of a first low-battery display 602 and a second low-battery display 604 when the video laryngoscope 102 is experiencing low-battery states. The first low-battery display 602 shows an open menu 610, including various indicators / icons (e.g., a connection status indicator 606A, a screenshot icon 612, a video-saving icon 614, and a low battery indicator 608). The connection status indicator 606A, screenshot icon 612, and video-saving icon 614, may be similar to the other connection status indicators, screenshot icons, and video-saving icons described herein. When the menu 610 is open and the battery life of the video laryngoscope 102 drops below a first threshold (e.g., 1 to 10 minutes remaining, such as 5 minutes remaining, 1-10% battery life remaining, etc.), the low battery indicator 608 may be displayed in the menu 610. The low battery indicator 608 may show a symbol associated with a low battery, such as a battery outline that is partially filled, and / or may show a number associated with the remaining battery life. The low-battery indicator 608 may flash when the battery life drops below the first threshold. When the menu 610 is hidden, the low-battery indicator 608 may replace the battery life indicator otherwise described herein (e.g., battery life indicator 407, 721). In some instances, the first low-battery display 602 may not be displayed.

[0069] The second low-battery display 604 shows when the battery life drops below a second threshold (e.g., 5 minutes remaining, 3 minutes remaining, 1 minute remaining, or less than 5% or less than 1% battery life remaining), or when a battery level cannot be measured or determined. The battery life indicator 616 in the second low-battery display may show an empty battery symbol and / or the battery symbol may be flashing. In an instance, the battery symbol may include a remaining battery life (e.g., as minutes or a percentage) until 0 minutes or 0% life is reached, when the battery symbol may show empty. In examples, the video laryngoscope 102 may have a built-in additional battery buffer of 5-10 minutes or associated percentage, after zero battery life is indicated on the display screen. This state below the second threshold may otherwise be referred to as a second low-battery state (e.g., dropping below the second threshold), with the first low-battery state defined by a battery level between the first threshold and the second threshold. Alternatively, if the first low-battery state is bypassed (e.g., the first low-battery display 602 is not shown), then this state may be referred to as the low- battery state (e.g., dropping below a threshold). In the second low-battery state (e.g., the battery level is not detected or drops below the second threshold), some functionality of the video laryngoscope 102 may be disabled. For example, in the second low battery state, touchinteractions with the display screen may be disabled (e.g., touch-screen interactivity may be deactivated), wireless connectivity may be disabled / deactivated (e.g., as shown nonconnectivity status indicator 606B), video recording and / or still-shot image capture may be disabled / deactivated or ended, and / or the menu 610 may automatically close (and / or no menu may be openable or selectable). The camera feed may continue to be displayed until the video laryngoscope 102 powers down. In some examples, the camera (e.g., camera feed) may also be disabled at an even lower battery state, followed by disabling ofthe display screen (e.g., turning off power to the screen) at yet a lower battery state. In an example where the camera (e.g., camera feed) is disabled, the display of the video laryngoscope may be empty (e.g., the screen may be black or darkened) except for an outline of a battery (e.g., an empty battery life indicator 616), which may flash. By conserving energy in such a manner, the remaining minimal battery life may be used to power a light source near the camera to illuminate the airway to allow for the clinician to still directly visualize (without video) the airway of the patient to complete the intubation procedure).

[0070] Additionally, in the second low-battery state, the battery life indicator (e.g., low- battery indicator 608 or battery life indicators 407, 721), may be replaced with a different low- battery indicator 616. The low battery indicator 616 associated with the second low-battery state may be an outline of a battery with no fill. The low battery indicator 616 may flash. Additionally or alternatively, warning text may be displayed (e.g., “Unknown battery life remaining,” “Warning: low battery,” etc.). Although FIG. 9 shows display screens 600 during intubation of a patient, the low-battery indicators described may be displayed in any display screen 600 showing the battery life (e.g., during routine use or in non-operational modes).

[0071] FIGS. 10-13 and 14A-14D, show example display screens 700 of a video laryngoscope 102 during non-operational modes of the video laryngoscope. FIG. 10 shows example display screens of a video laryngoscope during selection options for non-operational modes. FIG. 11 shows example display screens of a video laryngoscope during fde sharing of stored, acquired images. FIGS. 12, 13, and 14A-14D show example display screens of a video laryngoscope during selection of various settings.

[0072] Referencing FIG. 10, to access non-operational functionality of the video laryngoscope 102 (e.g., viewing and / or transferring locally stored fdes, changing device settings, or other non-routine use), an operator may long-press a power button of the video laryngoscope 102 (e.g., a press and hold of the power button for 2, 3, 4, 5, or more seconds). The long-press of the power button may be during a powered-off state of the video laryngoscope 102 (e.g., flow from display 402 to initial display 702). Alternatively, the long-press of the power button to access non-operational functionality may be during a powered-on state of the video laryngoscope 102 (e.g., flow from display 404, 406, 408 to initial display 702). In examples, a user may continue to hold the power button when navigating non- operational functionality display screens 700. In such an instance, a release of the power button may exit non-operational functionality (e.g., return to routine use) or power off the video laryngoscope 102. Other interactions with the video laryngoscope 102 may be performed to access the configuration settings discussed herein. The initial display 702 for non-operational functionality may show product and / or brand information, or any other indication of a special mode startup (such as a progress bar or loop, explanatory text, etc.). The initial display 702 may appear for a settings initialization period, after which a selection menu display 704 may be shown. Alternatively, after the settings initialization period, the initial display 702 may flow to settings display 722 (e.g., bypassing selection menu display 704, selection menu timeout display 706, and various displays shown in FIG. 11).

[0073] The selection menu display 704, may include icons for various non-operational functionality of the video laryngoscope 102. For example, as shown in selection menu display 704, a settings icon 705 and a stored media icon 707 may be displayed for selection by an operator of the video laryngoscope 102. Other information may also be shown on selection menu display 704, such as a software version number, product identification number, or other information. An interaction with the settings icon 705, or an interaction in proximity to the settings icon 705, may result in flow to settings display 722. An interaction with the stored media icon 707, or an interaction in proximity to the stored media icon 707, may result in flow to media listing display 708. If no input or interaction is received at the display screen for a timeout period, selection menu timeout display 706 may be shown. Alternatively, a long press of the power button (e.g., 5, 8, 10 or more seconds) may result in display of the selection menu timeout display 706. The selection menu timeout display 706 may show the same icons as the selection menu display 704 (e.g., a settings icon 705 and a stored media icon 707), in addition to a code 709. The code may be a series of numbers for identification or diagnostics, a scannable code (e.g., QR code, such as the troubleshooting QR code shown in troubleshooting display 723), or any other code for troubleshooting the video laryngoscope 102. Similar to the selection menu display 704, an interaction at or near the settings icon 705 may result in flow to settings display 722 and an interaction at or near the stored media icon 707 may result in flow to media listing display 708.

[0074] FIG. 11 shows display screens 700 relating to viewing, selection, and / or transfer of media stored locally on the video laryngoscope 102. At media listing display 708, a list oflocally stored media is displayed (e.g., first still-shot image 711, video image 713, second stillshot image 715, a third still-shot image 717, etc.). Each media file in the list of media files may include various information, including a thumbnail image associated with the media file, a file name, a symbol indicating media type (e.g., still-shot image, video image, audio file, information file, etc.), and / or a selection icon for selecting the media file. Media files may be organized in one or more folders, based on an amount of time that has passed since the media file(s) were captured. Media file names may be associated with a naming convention already saved to a connected device. Media files may be automatically deleted from the local storage of the video laryngoscope 102 after a threshold storage time (e.g., 2-10 days, such as 5 days). A connection status indicator 719 (which may be similar to connection status indicators 405, 504, 606A, 606B) and abattery life indicator 721 (which may be similarto battery life indicator 407) may be displayed. Additionally, text may appear on the media listing display 708, informing an operator of the video laryngoscope 102 to select files (e.g., “Select files”).

[0075] Certain user interactions with a thumbnail of a media file (e.g., first still-shot image 711, video image 713, second still-shot image 715, a third still-shot image 717) may result in enlarged thumbnail display 710. In examples, such interaction may be a long press and / or a long press and hold of the thumbnail and / or media file listing. The interacted thumbnail 723 may be enlarged and overlaid over top of the media listing display 708. Visible portions of the media listing display 708 may be dimmed behind the interacted thumbnail 723. An interaction with the enlarged thumbnail display 710 may return the display screen to media listing display 708 (e.g., closing or resizing the interacted thumbnail 723). In examples, an interaction to return to media listing display 708 may be a release of a long-press or hold, a tap, a double tap, a swipe, or any other touch interaction.

[0076] After at least one media file is selected (e.g., via a tap interaction with a selection icon associated with a media file), the display screen may show a media selection display 712. The media selection display 712 may include a media transfer icon 725. The media transfer icon 725 may include a symbol informing an operator that a selection of the media transfer icon 725 may allow the operator to transfer the selected media file(s) . If the video laryngoscope 102 is connected (e.g., no wireless connection to a device or system facilitating wireless communication and no wired connection detected), the media transfer icon 725 may be hidden, dimmed, or not selectable. In such an instance, text may be shown indicating that the video laryngoscope 102 is not connected (e.g., “No Relays connected,” “No wireless connection,” “No wired or wireless connection detected,” etc.).

[0077] After the media transfer icon 725 is selected, a loading display 714 may be shown for a loading time. The loading time may be a length of time associated with connecting with all available connected devices. The loading display 714 may include a progress bar, load bar, or other indicator of loading progress. Additionally or alternatively, text may be displayed to indicate that the video laryngoscope 102 is determining a list of all available / connected devices (e .g . , “Waiting for McGrath Relays ...”). At device list display 716, a list of available / connected devices (e.g., hubs, modules, and / or relays) are displayed for selection to transfer selected media files. The list of available / connected devices may include symbols and / or names representing and / or identifying the devices. The symbols may include an indicator of wireless or wired connection with the video laryngoscope 102 (e.g., device 200547 is shown with a wired connection and devices 200164, 200266, 200357 are wirelessly connected). A user interaction with one or more available / connected devices may select the devices for transfer of the selected media files. After one or more devices have been selected, transfer display 718 is shown. During transfer of the selected media files, a progress bar or progress loop or other progress indicator may be displayed to show transfer progress with each of the selected devices. In the example shown in transfer display 718, devices 200164 and 200266 are selected for media file transfer. After transfer of the selected media files is complete, transfer complete display 720 is shown, with an indicator of a complete transfer to each of the selected devices.

[0078] FIG. 12 shows display screens 700 relating to settings of the video laryngoscope 102, beginning with a settings menu display 722. The settings menu display 722 allows a user of the video laryngoscope 102 to configure save options (e.g., a selection of the “Save Options” option); recover backup files stored on the video laryngoscope 102 to a remote device (e.g., a selection of the “Backup Recovery” option); manage the device storage or settings on the video laryngoscope 102, including updating or restoring software, deleting local media files, and / or resetting device defaults (e.g., a selection of the “Manage Device” option); access a user manual and / or quick start guides associated with the video laryngoscope 102 (e.g., a selection of the “User Manual” option); and / or set the language for all text used in the user interface of the video laryngoscope 102 (e.g., a selection of the “A^i” option).

Additionally, the menu may include menu indicators and / or icons, such as a still-shot image capture icon (e.g., such as screenshot icon 415A-415E), a video-saving icon (e.g., such as video-saving icon 417A-417F), a low battery indicator (e.g., such as low battery indicator 608, 616), a connectivity status indicator (e.g., such as connection status indicators 405, 504, 606A, 606B, 719), etc.

[0102] At operation 812, input is received at the menu. The input received at the menu may instruct, or cause, the video laryngoscope to capture media (e.g., video images and / or still-shotimages). In an example, a user interaction with the still-shot image capture icon may cause the video laryngoscope to capture a still-shot image of the currently displayed acquired image. In another example, a user interaction with the video-saving icon may cause the video laryngoscope to capture a video image of the entire ongoing procedure (e.g., beginning at a power on state of the video laryngoscope). The captured media may be stored locally in memory of the video laryngoscope in one or more folders (e.g., a main folder and / or a backup folder). Other interactions with the menu are further described at least with respect to FIGS. 6A-6C.

[0103] At operation 814, the menu is hidden. The menu may be closed or hidden manually or automatically. The menu may be manually closed based on receiving a touch interaction (which may be received withing or near the menu portion of the display screen). In examples, touch interactions to manually hide the menu may include a swipe down, a swipe from right to left, a tap, a double-tap, or any other gesture inside, near, or outside the menu region. The menu may be automatically closed (or may be automatically hidden) after a menu timeout period (e.g., after 5 seconds), when no touch interaction is received during the menu timeout period.

[0104] At operation 816, a second set of indicators is displayed (e.g., after the menu is closed or hidden). The second set of indicators may include all or some of the indicators of the first set of indicators. If no media is captured at operation 812, the second set of indicators may be the same as the first set of indicators. If, alternatively, media is captured at operation 812, the second set of indicators may be different than the first set of indicators. For example, if still-shot images are captured, the second set of indicators may also include an indicator of stillshot image count (e.g., such as still-shot image indicator 419A, 419B). In another example, if a video image is captured, the second set of indicators may also include an upload indicator (e.g., such as upload indicator 421A, 421B). If a battery state of the video laryngoscope changed between displaying the first set of indicators and the second set of indicators, then the battery life indicator may appear different (e.g., as discussed in reference to FIG. 9). Similar to the first set of indicators, each indicator of the first set of indicators is positioned along a bottom edge of the display screen. Each indicator may be partially transparent to not completely obscure a portion of the displayed, acquired images over which the indicators overlay.

[0105] At operation 818, the captured media (if any media is captured at operation 812) is transferred. Some or all of the captured media may be transferred to one or more connected devices (e.g., connected via a wired or wireless connection). Transfer may be automatic, prior to shutting down the video laryngoscope (e.g., as described in FIG. 7). Additionally or alternatively, media file transfer may be accessed at a later time (e.g., as described in FIGS. 11,13). For example, locally stored media files may be presented in a media list (e.g., as shown in media listing display 708). One or more media files in the media list may be selected (e.g., via a touch input) and then transferred (e.g., by receiving a transfer input at the display screen). A list of available, connected devices (e.g., for transfer), may then be displayed in a device list (e.g., as shown in device list display 716). A user of the video laryngoscope may select one or more connected devices on the device list to transfer the selected media files to the selected device (s).

[0106] FIGS. 16A-16C show example display screens 900 of an extemal / remote device connected to a video laryngoscope (e.g., streaming the display of the video laryngoscope). Each of the example display screens 900 (e.g., displays 902-914, 920, 922) may include a streaming portion 916 and an information portion 918. When a video laryngoscope is connected (e.g., via wired or wireless connection) to the extemal / remote device, the streaming portion 916 may include a real-time streaming feed of the display of the video laryngoscope. When the video laryngoscope is not connected to the extemal / remote device, the streaming portion 916 may include information associated with troubleshooting connectivity and / or status of the video laryngoscope. The information portion 918 may include information associated with identification of the connected video laryngoscope (e.g., brand information, product information, serial number, other identification information, etc.) and / or information specific to the current use session (e.g., amount of time elapsed streaming, amount of time elapsed since the video laryngoscope was powered on, etc.).

[0107] The example display screens 900 shown in FIG. 16A (e.g., displays 902-914) show the streaming portion 916 above the information portion 918 (e.g., portrait orientation). Depending on dimensions and / or orientation of the extemal / remote device display, the streaming portion 916 may appear side-by-side with the information portion 918 (e.g., landscape orientation) or in a different relative orientation. Examples of landscape orientations of display screens 900 are shown in FIGS. 16B-16C (e.g., displays 920, 922). For instance, idle display 920 shows an alternative orientation for idle display 904 (further described below). In another instance, insufficient power display 922 shows an alternative design for the streaming portion 916 and an alternative orientation for insufficient power display 906 (further described below). In some examples, the streaming portion 916 may be sized to fill at least one dimension of the display of the extemal / remote device (e.g., enlarged such that a width of the streaming portion 916 is the width of the display and / or a height of the streaming portion 916 is the height of the display, whichever dimension is maximized first). In another example, the streaming portion may be enlarged to a maximum size and / or image quality at the display. The some orall of the information displayed in the information portion 918 may change in relative size compared to the streaming portion 916, depending on the orientation of the display screens 900. For example, a timer and / or identification information may be enlarged relative to the streaming portion 916 in a landscape orientation as compared to a portrait orientation.

[0108] At connectivity troubleshoot display 902, information may be shown at the streaming portion 916 to indicate a detected connectivity problem. For example, a code (e.g., a series of numbers for identification or diagnostics, a QR code or other scannable code, or any other code for troubleshooting the connectivity of the video laryngoscope with the extemal / remote device) may be displayed to facilitate troubleshooting connectivity. A nonconnectivity status indicator may also be displayed at the streaming portion 916 of the connectivity troubleshoot display 902 to indicate non-connectivity and / or a wireless connection issue. Because a video laryngoscope is not yet connected at connectivity troubleshoot display 902, the information portion 918 may be inactive (e.g., blank and / or lightened or greyed out, such as a timer showing 0:00 and a serial number being blank or empty). If no connectivity issues are detected, idle display 904 may be shown.

[0109] At idle display 904, the extemal / remote device may not yet be connected to a video laryngoscope (e.g., the extemal / remote device is awaiting connection with a video laryngoscope). Because a video laryngoscope is not yet connected at idle display 904, the information portion 918 may be inactive.

[0110] When a connection is forming between the extemal / remote device and a video laryngoscope (e.g., a data transfer connection and a power connection, such as connection via an HDMI and USB port), connecting display 910 may be shown. A connection indicator may be shown at the streaming portion 916 of the connecting display 910 to indicate a connection with a video laryngoscope is in progress (e.g., a progress bar, progress loop, or other indicator associated with connection progress). Because a video laryngoscope is not yet connected at connecting display 910, the information portion 918 may be inactive. When a connection is formed, flow proceeds to streaming display 912.

[0111] If a partial or incomplete connection is formed between the extemal / remote device and a video laryngoscope, flow may proceed to either insufficient power display 906 or dark idle display 908. If a data transfer connection is established (e.g., via an HDMI port) without detecting an accompanying power connection (e.g., via a USB port), insufficient power display 906 may be shown. Additionally, a threshold time period (e.g., 5 seconds, 10 seconds, or more) may be met or exceeded prior to display of insufficient power display 906. At insufficient power display 906, information may be provided at the streaming portion 916 to indicate thatthe connection is not sufficiently powered. The information displayed at the streaming portion 916 of insufficient power display 906 may include a plugging indicator or animation, a code to facilitate finding more information, and / or a power symbol / icon. Because a video laryngoscope is not yet connected at insufficient power display 906, the information portion 918 may be inactive. Establishment of a power connection may result in display of idle display 904 (e.g., if the connection is not yet forming, such as a video laryngoscope that is idle or powered off) and / or connecting display 910 (e.g., if the connection is forming).

[0112] If a data transfer connection and power connection are established, but the associated video laryngoscope is not powered on for at least a period of time (e.g., 2 minutes, 3 minutes, 4 minutes, 5 minutes, or more), dark idle display 908 may be shown. Dark idle display 908 may be similar to idle display 904, but may be darker or dimmed. Because a video laryngoscope is not yet connected at dark idle display 908, the information portion 918 may be inactive. If a connection is initiated (e.g., the video laryngoscope is moved, interacted with, and / or powered on) flow may proceed to connecting display 910 (e.g., a connection is forming).

[0113] At streaming display 912, a real-time display of the video laryngoscope is streamed for display at the streaming portion 916 of the streaming display 912. The information portion 918 may be active and include a serial number and / or other identification information for the connected video laryngoscope and / or a dynamic timer. If the video laryngoscope is powered off, flow proceeds to idle display 904.

[0114] If the video laryngoscope is idle (e.g., no motion and / or no user interaction at the video laryngoscope) for at least a first idle threshold period of time (e.g., 10 seconds, 15 seconds, 20 seconds, etc.), flow proceeds to dim mode display 914. At dim mode display 914, both the streaming portion 916 (e.g., displaying the video stream of the video laryngoscope) and / or the information portion 918 may be darker, dimmed, and / or inactive. For example, the streaming video may dim and the timer may pause. If the video laryngoscope powers off or is idle for at least a second idle threshold period of time (e.g., 2 minutes, 3 minutes, 5 minutes, etc.), flow proceeds to idle display 904. If the video laryngoscope is awakened from its idle state (e.g., detects motion and / or any other indication of user interaction), flow proceeds to streaming display 912. In such an instance (e.g., restarting the streaming display 912 after displaying dim mode display 914), the timer may restart from 0:00 at the streaming display 912.

[0115] FIG. 17 shows an example display screen 1000 of a video laryngoscope (e.g., video laryngoscope 102) during battery de-passivation. If the video laryngoscope detects that a passivated battery is coupled with the body, a display screen 1000 may inform a user of batteryde-passivation. During the de-passivation process, the display screen 1000 may include a passivated battery indicator 1002. Additionally, the display screen 1000 may include information about video laryngoscope (e.g., brand, product, product type, identification information, etc.). The passivated battery indicator 1002 may be static or may change overtime (e.g., an animation). In an instance where the passivated battery indicator 1002 is an animation, a fill pattern inside of a battery outline may change over time to show activity on a battery symbol. The passivated battery indicator 1002 may inform an operator of the video laryngoscope that the coupled battery is de-passivating and that other functionality (e.g., operational and non-operational modes) may be available and / or displayed soon (e.g., after the battery is de-passivated).

[0116] FIG. 18 shows an example file 1100 captured during a use session of a video laryngoscope (e.g., video laryngoscope 102). A file 1100 captured by a video laryngoscope may include a captured portion 1102 and a watermark portion 1104. The captured portion 1102 may include the original file captured at the video laryngoscope (e.g., the camera feed shown at the time of a still-shot image capture, the screen displayed on the video laryngoscope at the time of a still-shot image capture, the video saved on the video laryngoscope during a use session, etc.). The watermark portion 1104 may include a border around, about, partially overlapping, or adjacent to the captured portion 1102. In an example, the watermark portion 1104 may include a border around the capture portion 1102 that may be similar in size and / or appearance of a border around a screen of the video laryngoscope. The watermark portion 1104 may include information about video laryngoscope that captured the file 1100 (e.g., brand, product, product type, identification information, etc.). Information included in the watermark portion 1104 may allow a viewer of the file 1100 to determine if the file 1100 is original, which device and / or product captured the file 1100, other unique identifying information about the file 1100 and / or the capturing device, etc. The watermark portion 1104 may be combined with the captured portion 1102 (e.g., to create the file 1100) at the video laryngoscope (e.g., prior to transfer of the file from the video laryngoscope to a relay and / or remote device). Alternatively, the file may be created after transfer of the captured video data or captured still-shot data to a remote device and / or relay from the video laryngoscope. For example, once received by the relay and / or remote device, the captured video data or captured still-shot data may be combined with the watermark portion 1104 to create the file 1100 (e.g., video file or still-shot image file).
