Description

Technical Field

[0001] The present invention relates to a device for use in an intubation procedure. More particularly, the present invention relates to a video laryngoscope. Background Art

[0002] A laryngoscope is a device, typically comprising a handle and a blade, used by clinicians during endotracheal intubation. A laryngoscope assists in intubation by allowing the clinician to visualize the path of the endotracheal tube as the laryngoscope is passed through the glottis toward the trachea.

[0003] Intubation is the process of inserting a tube called an endotracheal tube through the mouth and then into the airway. Intubation is a necessary procedure before any surgery that requires the patient to be given general anesthesia. Intubation is also done for patients who need to use a ventilator to assist with breathing. The endotracheal tube is connected to the anesthesia system or ventilator and pushes air into the lungs, delivering breaths to the patient. A laryngoscope is a device used for intubation.

[0004] Currently, conventional video laryngoscopes come in two configurations. In the first configuration, the display is separated from the handle and attached to a cart. The display attached to the cart has limited mobility. In addition, the display is 7-11 inches in size, and the cart is bulky and difficult to move around. When performing an intubation procedure, the clinician needs to look away from the patient and toward the display attached to the cart, and not looking at the patient increases the risk of procedure failure. In addition, cart-based systems tend to be more expensive, with hospitals purchasing some units for sharing by multiple operating rooms. This results in video laryngoscopes not being suitable for every intubation procedure. In the second configuration, the display is attached to the handle, but the display is small, the image quality is poor, and it is not manipulable. Both configurations result in increased risk to the patient and lead to repeated intubations.

[0005] In addition, conventional video laryngoscopes include reusable blades that are used repeatedly for intubation procedures. The reuse of blades results in a higher risk of infection, increased operational burden on hospitals, and high cost of ownership.

[0006] Therefore, there is a need for a video laryngoscope that overcomes some or all of the disadvantages of the prior art. Summary of the invention

[0007] According to the present invention, a video laryngoscope is provided. The video laryngoscope may include a handle, a blade and an attachment mechanism. The handle may have an upper end and a lower end, and a camera channel extends from the lower end. The camera channel may have a camera receptacle with an image sensor to capture and transmit visual data of the patient's airway during intubation. The blade may be slidably attached to the handle to cover the entire surface of the handle in the attachment position. The blade may be securely attached using the attachment mechanism, which may be arranged at the upper end of the handle.

[0008] The attachment mechanism may include at least two spherical protrusions that are biased to extend radially outward from the central portion of the handle. The two spherical protrusions can engage corresponding openings in the blade during the cannulation process to securely fix the blade in place. The two spherical protrusions can be biased using a biasing member that pushes the two spherical protrusions outward from the central portion of the handle. The blade can be removed from the handle by pressing the spherical protrusions inwardly, overcoming the biasing force and disengaging the two spherical protrusions from the corresponding openings in the blade.

[0009] The blade may include an attachment portion, a grip portion, and a tongue portion. The attachment portion may be adapted to be connected to a handle using an attachment mechanism. The grip portion may include a surface recess to provide a grip for a clinician during an intubation procedure. The tongue portion may accommodate a camera channel, and the tongue portion includes a camera receptacle opening configured to receive a camera receptacle so that the camera can capture visual data of the airway, larynx, trachea, and endotracheal tube. The tongue portion may be adapted to facilitate smooth insertion into a patient's airway.

[0010] The handle may also include a tapered portion at the lower end from which the camera channel extends. The camera channel may include a camera receptacle at the distal end of the camera channel for capturing visual data in the airway, trachea, or endotracheal tube and transmitting the visual data to a connected display unit.

[0011] In addition, the handle may include a receiving port adapted to receive the display unit. The receiving port may accommodate an attachment assembly, thereby allowing the display unit to be securely attached to and detached from the handle. The handle may include terminals exposed within the receiving port, which allow electrical connections to be established between the camera channel and the display unit, thereby enabling real-time visual feedback during intubation.

[0012] In another aspect, the handle can include a controller disposed within the handle body. The controller can connect the camera channel to the display unit, thereby allowing the captured visual data to be transmitted to the display unit. The terminals in the receiving port can include a first terminal in the handle and a second terminal on the display unit, and the terminals can establish an electrical connection between the camera and the display unit to ensure that the visual data of the airway is properly displayed during the intubation procedure.

[0013] The blade can be designed to enclose the handle and camera channel within cavities formed in the attachment portion and the grip portion. These cavities can allow the blade to slide over the handle and completely enclose the handle in the attached position. The tongue portion of the blade can include a camera receiving portion opening near the tip through which the camera can capture visual data of the patient's airway to enable the clinician to guide the endotracheal tube into the trachea with real-time visual feedback.

[0014] In a second aspect, a handle for a video laryngoscope is provided, which may include a body having an upper end and a lower end, and a controller. The upper end of the handle may include a receiving port adapted to receive a display unit, and the upper end of the handle may facilitate attachment of a blade to the handle. The lower end may be configured to connect a camera channel to the handle. A controller disposed within the handle may connect the camera channel to the display unit, thereby enabling transmission of visual data from an image sensor to the display unit. Terminals within the receiving port and the display unit may allow electrical connections to be established, thereby facilitating display of captured visual data.

[0015] In another aspect, the blade can be configured for use with a video laryngoscope, preferably with a handle, and the blade can include an attachment portion, a grip portion, and a tongue portion. The blade can be adapted to slide over the handle and camera channel, securely housing the handle within a cavity formed in the attachment portion and the grip portion. The blade can include at least two openings that engage with two spherical protrusions of the handle to secure the blade in place during intubation. The tongue portion of the blade can have a camera housing opening near the tip, allowing the camera housing to capture visual data in the airway, larynx, or trachea.

[0016] In addition, the blade may include a first cavity in the attachment portion and the grip portion to accommodate a handle, and a second cavity in the tongue portion to accommodate a camera channel. The first cavity and the second cavity accommodate both the handle and the camera channel during the intubation process. In addition, the blade may include a surface recess on the grip portion to provide a grip for the clinician during the intubation process. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention provides a video laryngoscope. The video laryngoscope is adapted to seamlessly attach and detach a display unit and a blade from a handle. The video laryngoscope is adapted to avoid blurring and distortion of visual data of the path of an endotracheal tube. Furthermore, the video laryngoscope is adapted to control infection rates spread by conventional laryngoscopes. Furthermore, the video laryngoscope allows a clinician to perform an intubation procedure without sacrificing visibility of the display unit.

[0031] The terms "first", "second", etc. herein do not indicate any order, quantity, or importance, but are used to distinguish one element from another, and the terms "one" and "an" herein do not indicate a limitation of quantity, but indicate the presence of at least one of the referenced items. The disclosed embodiments are merely examples of the present invention, which may be embodied in various forms.

[0032] See also Figure 1 , Figure 2 and Figure 3 , a video laryngoscope (100) according to the present invention is shown. The video laryngoscope (100) comprises a handle (10), a blade (20) and an attachment mechanism (21) for attaching the blade (20) to the handle (10). The handle (10) is an elongated member having an ergonomic design that allows a clinician to easily hold the handle (10) during the intubation process. The handle (10) has an upper end (101) and a lower end (102). The upper end (101) of the handle (10) is provided with a receiving port (12) to receive a display unit (30).

[0033] The lower end portion (102) of the handle (10) is provided with a tapered portion (14). Specifically, the lower end portion (102) of the handle (10) is provided with a camera channel (15) extending from the tapered portion (14) of the handle (10). The camera channel (15) is a flexible connector extending from the tapered portion (14) of the handle (10), and the camera channel (15) includes a circuit to transmit visual data such as images and videos to the receiving port (12). The camera channel (15) has a first end connected to the tapered portion (14) of the handle (10) and a second end as the distal end of the camera channel, the second end including a camera housing (16). The camera housing (16) of the camera channel (15) is configured to capture visual data of the path of the endotracheal tube, larynx, trachea or airway.

[0034] refer to Figure 1 and Figure 2, the handle (10) is adapted to receive the blade (20) from the lower end (102) of the handle (10). The blade (20) is received around the outer surface of the handle (10) to completely cover the handle (10) and the camera channel (15). When performing the intubation process, the blade (20) is attached to the handle (10). The handle (10) is adapted to receive all types of blades, such as Macintosh type and Miller type, or adult blades and children blades. In addition, the camera channel (15) is adapted to receive all types of blades for both adults and children, such as Macintosh type and Miller type. The handle (10) does not require any other adjustment or installation to receive adult blades and children blades. The blade (20) can be slid on the camera channel (15) to be attached to the handle (10) to perform the intubation process. The blade (20) is attached to the handle (10) in a detachable manner, and the blade (20) can be detached from the handle (10) after the intubation process.

[0035] Reference now Figures 4a to 4c In the current embodiment of the present invention, the blade (20) can be attached to the handle (10) by an attachment mechanism (21) of the handle (10). The attachment mechanism (21) includes at least two spherical protrusions (211a, 211b) arranged opposite to each other to firmly attach the blade (20) to the handle (10) and remove it from the handle (10). The two spherical protrusions (211a, 211b) are biased to extend radially away from the central axis of the handle (10). The two spherical protrusions (211a, 211b) are configured to engage with the blade (20). Specifically, a biasing member (212) such as a spring is used to bias the two spherical protrusions (211a, 211b) to extend radially outward from the central portion of the handle (10). A biasing member (212) is located inside the handle (10), and the biasing member (212) applies a continuous force to the spherical protrusions (211a, 211b) to configure the extended position of the two spherical protrusions (211a, 211b) during the attachment of the blade (20). The two spherical protrusions (211a, 211b) have corresponding biasing members (212a, 212b) to bias the two spherical protrusions (211a, 211b) away from the handle (10), thereby engaging the blade (20) and maintaining the blade (20) in the attached position. When the blade (20) is attached, the spherical protrusions (211a, 211b) engage with corresponding openings (223a, 223b) in the blade (20), thereby maintaining the blade (20) around the handle (10).

[0036] In the present embodiment, the biasing member (212) is a compression spring. It will be obvious to those skilled in the art to use any other type of spring as the biasing member (212).

[0037] Reference now Figure 5 The blade (20) includes an attachment portion (251), a grip portion (252) and a tongue portion (253). The attachment portion (251) is located at the proximal end of the blade (20), and the attachment portion (251) is suitable for attaching the blade (20) to the handle (10). The attachment portion (251) includes at least two openings (223a, 223b) positioned to engage with two spherical protrusions (211a, 211b) of the handle (10). The two openings (223a, 223b) are arranged to engage with the corresponding two spherical protrusions (211a, 211b) during the intubation process. The attachment mechanism (21) allows the handle (10) to be disassembled by pressing the two spherical protrusions (211a, 211b) inwardly. The blade (20) has a first cavity (256) formed at the attachment portion (251) and the grip portion (252) of the blade (20). The first cavity (256) has a shape suitable for being mounted on and covering the handle (10) during the intubation process. The first cavity (256) allows the blade (20) to accommodate and remain securely in place with the handle (10) during the intubation process. The first cavity (256) is formed at the attachment portion (251) and extends through the grip portion (252).

[0038] The gripping portion (252) is the middle portion of the blade, and the gripping portion (252) is arranged between the attachment portion (251) and the tongue portion (253). The gripping portion (252) is configured to provide a grip for the clinician during the intubation process. The gripping portion (252) has a recess (not shown) or other surface texture on the outer surface of the gripping portion (252) to enhance the clinician's grip.

[0039] In addition, the tongue portion (253) is the distal end of the blade (20) located behind the grip portion (252). The tongue portion (253) is configured to interact with the patient's body structure, particularly during intubation. In this embodiment, the tongue portion (253) is an integral part of the blade (20), and the tongue portion (253) extends laterally from the grip portion (252). The tongue portion (253) is configured to receive the camera channel (15) and the camera receiving portion (16). The tongue portion (253) includes a camera receiving portion opening (165) to accommodate the camera receiving portion (16) facing the outside of the blade (20), thereby allowing the image sensor (161) arranged in the camera receiving portion (16) to capture visual data of the patient's airway including the endotracheal tube, larynx and trachea.

[0040] Specifically, the blade (20) has a second cavity (257) formed at the tongue portion (253) of the blade (20). The second cavity (257) is configured to accommodate a camera channel (15) and a camera receiving portion (16) therein. The second cavity (257) accommodates the camera channel (15), which extends along the length of the tongue portion (253). The second cavity (257) provides space for the camera channel (15) to be accommodated within the blade (20). In addition, the camera receiving portion (16) is exposed through a camera receiving portion opening (165) provided in the tongue portion (253) to allow the image sensor (161) to capture visual data of the patient's airway.

[0041] After the intubation process, the blade (20) can be removed from the handle (10) by pressing the two spherical protrusions (211a, 211b) against the biasing force applied by the biasing members (212a, 212b). When pressure is applied to the two spherical protrusions (211a, 211b), the two spherical protrusions (211a, 211b) are pushed inward, thereby overcoming the biasing force of the biasing members (212a, 212b) and moving toward the central portion of the handle (10) (e.g., Figure 4b The two spherical protrusions (211a, 211b) move toward the central portion of the handle (10) to disengage from the corresponding openings (211a, 211b) in the blade (20), thereby allowing the blade (20) to be removed from the handle (10). Specifically, when the two spherical protrusions (211a, 211b) are pressed, the blade (20) can slide on the handle (10) and the camera channel (15) in a downward direction (as shown). Figure 4c ), thereby completely removing the blade (20) from the handle (10) and discarding the blade (20) after the intubation process.

[0042] The blade (20) is discarded after being removed from the handle (10) to reduce the chance of infection and cross contamination. Discarding the blade (20) after a single use allows the video laryngoscope (100) to control the spread of infection that may be spread by repeated use of the same blade.

[0043] Reference now Figure 6 and Figure 7a to Figure 7b, shows a handle (10) for a video laryngoscope (100) according to a second embodiment of the present invention. The handle (10) includes a body (11) and a controller (19) disposed in the body (11). The body (11) has an upper end (101) and a lower end (102). The upper end (101) is adapted to receive a display unit (not shown) through a receiving port (12) and simultaneously connect a blade (20) to the handle (10). The upper end (101) of the handle (10) has an attachment mechanism (21) disposed in the receiving port (12) to attach the blade (20) to the handle (10). The attachment mechanism (21) includes at least two spherical protrusions (211a, 211b), and the spherical protrusions (211a, 211b) extend radially away from the central portion of the handle (10). The two spherical protrusions (211a, 211b) may engage with the blade (20) to securely hold the blade (20) in an attached position.

[0044] The lower end portion (102) is configured to connect the camera channel (15) to the handle (10). Specifically, the handle (10) has a tapered portion (14) disposed at the lower end portion (102) of the body (11) to guide the blade (20) while the blade (20) slides on the handle (10) for attaching the blade (20) to the handle (10). In addition, the camera channel (15) extends from the tapered portion (14) and is connected to the controller (19).

[0045] The controller (19) is arranged in the body (11). The controller (19) is adapted to be electrically connected to the display unit (30) and the camera channel (15). Specifically, when the display unit (30) is attached to the handle (10), the controller (19) is adapted to be connected to the display unit (30) through a terminal exposed in the receiving port (12). The terminal is configured to establish a connection between the display unit (30) and the camera channel (15) to send visual data of the path of the endotracheal tube, larynx, trachea or airway to the display unit (30).

[0046] Specifically, the handle (10) includes a first terminal (122) disposed in a receiving port (12) at an upper end (101) of the handle (10). The first terminal (122) is configured to be electrically connected to a corresponding second terminal (28) located on a display unit (30). The first terminal (122) and the second terminal (28) are configured to establish an electrical connection between the handle (10) and the display unit (30) when the display unit (30) is attached.

[0047] The first terminal (122) provides a connection interface for an image sensor (161) housed in the camera housing (16). When the display unit (30) is attached to the receiving port (12), the second terminal (28) on the display unit (30) aligns with the first terminal (122) on the handle (10), thereby establishing an electrical connection. The electrical connection enables the transmission of visual data captured by the image sensor (161), which is located in the camera housing (16) at the distal end of the camera channel (15).

[0048] When the display unit (30) is attached to the handle (10), the controller (19) receives an electrical signal from the image sensor (161) and transmits the electrical signal to the display unit (30). The controller (19) processes the visual data of the trachea, larynx or airway and displays it on the screen (34) of the display unit (30), thereby enabling the clinician to monitor the intubation process in real time. The electrical connection between the image sensor (161), the controller (19) and the display unit (30) facilitates visual feedback throughout the intubation process. The first terminal (122) and the second terminal (28) allow the display unit (30) to be quickly attached to or detached from the handle (10) without any additional wiring.

[0049] Reference now Figure 8 , the camera housing (16) includes an image sensor (161) and a light source (162). The image sensor (161) facilitates capturing visual data of the path of the endotracheal tube, larynx, trachea or airway. Specifically, an image sensor opening (1611) in the camera housing (16) allows the image sensor (161) to capture visual data of the path of the endotracheal tube, larynx, trachea or airway. In this aspect of the invention, the image sensor (161) is a 2 megapixel (MP) camera, but a person skilled in the art may use any other image sensor (161) with different specifications.

[0050] In addition, the camera housing (16) includes a light source opening (1621) to allow the light source (162) to illuminate the path of the endotracheal tube and the airway. In addition, the camera housing (16) has a baffle (18). Specifically, the baffle (18) is disposed on the outer surface of the camera housing (16) to separate the image sensor opening (1611) from the light source opening (1621). The baffle (18) prevents the light source (162) from being directly exposed to the image sensor (161).

[0051] In this aspect of the invention, the baffle (18) is a rectangular strip. The rectangular strip is made of silicone material. A person skilled in the art can construct the baffle (18) into any other material, shape or size according to the size and position of the image sensor (161) and the light source (162). The baffle (18) is horizontally arranged between the light source opening (1621) and the image sensor opening (1611) to prevent light from being scattered on the image sensor (161).

[0052] Reference now Figure 8 and Fig. 9 , the baffle (18) includes a rectangular portion (181) and two leg-shaped members (182a, 182b) extending from the ends of the rectangular portion (181). The two leg-shaped members (182a, 182b) are provided with respective locking elements (1821a, 1821b) to attach the baffle (18) to the camera accommodating portion (16). Specifically, the camera accommodating portion (16) has two openings (not shown) to receive the locking elements (1821a, 1821b) of the two leg-shaped members (182a, 182b), thereby retaining the baffle (18) on the outer surface of the camera accommodating portion (16). The baffle (18) is fixedly attached to the camera accommodating portion (16) using the locking elements (1821a, 1821b), but those skilled in the art may provide the baffle (18) to be detachable from the camera accommodating portion (16). Specifically, if the baffle (18) is damaged or needs to be replaced, the baffle (18) can be removed from the camera housing (16).

[0053] In another aspect of the present invention, the baffle (18) is a protrusion (not shown) extending from the outer surface of the camera housing (16). The protrusion is disposed between the image sensor opening (1611) and the light source opening (1621) to prevent light from being directly irradiated from the light source (162) to the image sensor (161). The scattering of light from the light source (162) distorts and blurs the image. The baffle (18) prevents the light source (162) from directly irradiating the image sensor (161), thereby preventing distortion and blurring of the image.

[0054] In another aspect of the present invention, the baffle (18) is a thin sheet disposed between the image sensor opening (1611) and the light source opening (1621). The thin sheet can be made of any material that absorbs light, thereby preventing the light source (162) from directly irradiating the image sensor (161).

[0055] Reference now Figure 1 and Fig.10A display unit (30) is provided, which can be attached to the handle (10) via an attachment assembly (25). The attachment assembly (25) includes a housing (27) and a second terminal (28) electrically connected to the display unit (30). The housing (27) is connected to the display unit (30) using a hinge (26). The hinge (26) is configured to allow the display unit (30) to pivot back and forth. The hinge (26) is connected to the display unit (30) and the housing (27). Specifically, the hinge (26) has a connecting element (not shown) suitable for attachment to the housing (27). The housing (27) receives the connecting element of the hinge (26) to allow the display unit (30) to rotate freely around the central axis of the handle (10). The hinge (26) allows the display unit (30) to rotate in all possible directions to configure the display unit (30) in a desired position, thereby providing better visibility for the clinician.

[0056] In addition, the housing (27) includes at least two spherical protrusions (271a, 271b) extending from the outer surface of the housing (27) and arranged opposite to each other to securely attach the housing (27) to and detach it from the handle (10). The two spherical protrusions (271a, 271b) are offset to extend radially away from the central axis of the housing (27). The housing (271a, 271b) is attached to the receiving port (12) of the handle (10) (such as Figure 7a ). Specifically, the receiving port (12) has two openings (121a, 121b) to receive the corresponding spherical protrusions (271a, 271b) of the housing (27), thereby firmly holding the housing (27) in the receiving port (12) of the handle (10). The two spherical protrusions (271a, 271b) ensure that the housing (27) is held in place until the two spherical protrusions (271a, 271b) are pressed to remove the housing (27) of the attachment assembly (25). Specifically, the two spherical protrusions (271a, 271b) are respectively provided with spherical pieces at the end portions, so that the two spherical protrusions (271a, 271b) can be easily pressed when the housing (27) is removed from the handle (10).
