Definitions
- the present invention relates to endotracheal tubes and, in particular to an
- the invention has been developed primarily for use by anaesthetists in clinical or surgical environments and will be described hereinafter with reference to this application. However, it will be appreciated that the invention is not limited to this particular field of use and can be used outside of clinical or surgical environments.
- ETT endotracheal tube
- intubation an endotracheal tube
- the anaesthetists intubate the airways of a patient to provide air which the patient would not otherwise be able to breathe on their own whilst under the anaesthetic. It is typical foi the surgical patient to be in a supine position when anaesthetised.
- the ETT has a relatively large diameter so that it can be practically difficult and dangerous to insert without assistance.
- This is performed with an introducer which essentially is a flexible shaft or rod that can be bent to an approximate desired shape and over which the ETT 'can be slid.
- introducers are often known as "bougies".
- the shaft is able flex to accommodate the shape of the anatomy during insertion, this being especially important in patients having an anatomy making intubation difficult, or in obese and other patients where the path may be narrowed or deformed.
- the diameter of the introducer is relatively significantly smaller than the ETT diameter and provides the anaesthetist with some field of vision thereabouts.
- a laryngoscope is a well-known device for assisting in the process of intubation.
- a laryngoscope includes a handle and a blade, one common type being a "Mackintosh blade".
- An eye piece is disposed in the laryngoscope blade which allows the anaesthetist to look in a substantially straight line direction at the epiglottis or trachea entrance when the laryngoscope is in place. This allows the anaesthetist to more accurately know when the tracheal tube can be inserted.
- the laryngoscopes were improved by including a light source at or adjacent to the blade tip to provide lighting and improve the view through the eye-piece. More recently, cameras have been fitted at or adjacent the end of the blades to provide real time images of the position of the end of the blade.
- the first has a flexible scope shaft with a light source and camera/lens disposed at the tip of the shaft. This is attached to a handle with a monitor for viewing by the anaesthetist.
- An ETT is disposed over the scope shaft prior to it being inserted into the patients oral cavity. The tongue is moved by the blade and the epiglottis moved clear of the trachea.
- the tip of the scope shaft is disposed over the trachea in this arrangement and the ETT about the scope shaft is slid off into the trachea while the scope is removed.
- the second type of laryngoscope is the Pentax airways scope (AWS-S100).
- the Pentax laryngoscope is similar to the first type of laryngoscope except that the shaft and tip of the scope are fed into a Mackintosh blade with a scope window at a handle end.
- the one side of the blade includes a groove to retain a tracheal tube or introducer. Once in place and visual confirmation of the glottis is achieved after moving the epiglottis the tracheal tube or the introducer are slid down the retaining groove in the Macintosh blade.
- the disclosure also makes reference to there being some form of switch which is preferably sealed within the device.
- the device needs to be discarded in the event the switch malfunctions, the batteries fail or some damage occurs to the outer surface thinned to fit the components and not exceed the existing introducer diameter which is fixed by human anatomy, for example.
- the genesis of the invention is a desire to overcome or substantially ameliorate one or more of the disadvantages of the prior art, or to.provide a useful alternative.
- an endotracheal tube introducer comprising:
- a flexible elongate tubular bodj' extending between an insertion end terminating at an insertion tip and a manipulation end;
- a camera disposed at or adjacent said insertion tip and positioned to receive images in a field of view from an area in front of said insertion tip;
- a light source disposed at or adjacent said insertion tip and positioned to emit light to illuminate said field of view;
- introducer connector mounted at said manipulation end of said introducer, said introducer connector having electrical contacts accessible from said manipulation end and connected to camera and light electrical wiring extending within said body;

- monitor controller configured to be connected to said monitor connector to control said camera and said light source and to receive images from said camera and wherein an endotracheal tube is slidable from said manipulation end over said introducer connector towards said insertion tip end when said monitor connector is disconnected from said introducer connector and
- a display monitor associated with the monitor controller and configured to display images from said camera field of view.
- the introducer includes a conduit disposed within said introducer body and extending from said manipulation end and accessible therefrom to said insertion end and accessible therefrom, said conduit configured to pass air or other materials therealong from the manipulation end to the insertion end.

- an endotracheal tube introducer 1 is in the form of a solid tube or rod formed from PVC plastics material.
- the introducer 1 is extruded to a predetermined length preferably between 600mm and 900mm long.
- the diameter of the introducer 1 is approximately 5mm and this can be selected as desired. It will be appreciated that the introducer 1 is longer than a desired endotracheal tube that is to be slid thereover once positioned in place.
- the introducer 1 can be made of any preferred material provided it is flexible and cylindrical. Further, the introducer 1 need not be solid.
- the introducer 1 extends between the insertion end 3 and a manipulation end 4.
- the introducer 1 terminates at the insertion end 3 at an insertion tip 5.
- the introducer 1 is able to be handled by a practitioner at the manipulation end 4.
- the introducer 1 may be bent off axis by a predetermined amount on or about the manipulation end to assist with handling and use by the practitioner.
- a camera 6 at the insertion tip 5 of the introducer 1.
- the camera 6 is positioned to receive images in the field of view that extends in an area in front of the insertion tip 5.
- a light source 7. This is also disposed at the insertion tip 5.
- the light source 7 is an LED positioned to emit light from the insertion tip 5. This light is intended to illuminate a direction ahead of the introducer 1 as it is moved toward the glottis. This light is detected by the camera 6 and provides vision for the practitioner or other people.
- the light source 7 and the camera 6 are hermetically sealed within the introducer 1 and sit right at the insertion tip 5.
- a window may be formed from the front of the camera 6 and the light source 7 disposed at the insertion tip 5 to minimise image distortion.
- the camera 6 and the light source 7 are integrally formed on a single circuit board.
- the camera 6 is preferably a high resolution video camera and this can be provided as desired.
- Electrical wires are disposed within the introducer body 2. These are connected to the camera 6 and the light source 7 and extend within the body 2 from the camera 6 and light 7 substantially to the manipulation end 4.
- the electrical wiring provides power to the light source 7 and a camera 6 and also receives signals from the camera 6 and provides control signals thereto.
- An introducer connector 8 is disposed at the manipulation end 4 of the introducer 1.
- the introducer connector 8 includes electrical contacts 9 accessible from the outside of the introducer body 1 at the manipulation end 4.
- Internal contacts 10 are connected to the electrical wiring and those contacts 10 are also hermetically sealed within the introducer body 2.
- the internal contacts 10 are integrally formed through the body of the introducer connector 8 and terminate at the external electrical contacts 9.
- the external electrical contacts 9 are accessible from outside the introducer body 2 at the manipulation end 4.
- a monitor connector 12 is configured to releasably attach to the introducer connector 8.
- the monitor connector 12 includes electrical contacts (not illustrated) to electrically connect with corresponding external contacts 9 of the introducer connector 8. That is, the monitor connector 12 connects to the electrical wiring extending to the camera 6 and the light source 7 for communication therewith.
- monitor controller 13 electrical wiring extends from the monitor connector 12 to a monitor controller 13, shown in a schematic view of a system 20 employing introducer 1 in Fig. 2.
- the monitor controller 13 is configured to operate the camera 6 and the light source 7.
- the monitor controller 13 in the preferred embodiment also receives and displays the images provided by the camera 6 on a video display 14.
- the monitor connector 12 and the introducer connector 8 releasably engage with each other in a mechanical arrangement that most preferably is able to be disconnected by the practitioner with one hand.
- the patient to receive the endotracheal tube (not illustrated) is laid in a supine position and positioned to receive the introducer 1 through the oral cavity and into the glottis.
- the monitor connector 12 is connected to the introducer connector 8. This provides power to the camera 6 and the light 7 and allows images from the camera 6 to be displayed on the video display 14.
- the insertion end 3 is inserted through the oral cavity down the throat into the glottis, and it will be appreciated that a Macintosh blade or the like can be used to assist in clearing the tongue and epi-glottis.
- the monitor connector 12 is disconnected and an endotracheal tube slid over the introducer 1 from the manipulation end 4.
- the introducer connector 8 has substantially the same diameter as the introducer body 2 so as not to impede movement of the endotracheal tube thereover.
- the introducer connector 8 at the manipulation end 4 can be shaped on an outer circumference to act as a handle when connected to the monitor connector 12.
- the monitor connector 12 may be reconnected to the introducer connector 8 once the endotracheal tube has been received past the manipulation end 4 of the introducer body 2.
- the introducer 1 is then withdrawn leaving the endotracheal tube in place.
- the endotracheal tube is then connected to an oxygen or air source for the patient.
- the introducer 1 may be a single use device which is disposed of after use. In the alternative, it may be able to be cleaned and sterilised or autoclaved for reuse in a subsequent patient. It can be seen that the introducer 1 is relatively cheaply produced when compared to prior art wireless introducers whilst offering substantially all the same benefits.
- the introducer I of the preferred embodiment is particularly advantageous over the Pentax airway scope, for example, of the prior art.
- the introducer 1 lacks the physical dimension or bulk that the Pentax scope possesses which allows improved access when a patient's mouth cannot be opened beyond a limited amount.
- the intubation process is simplified over that art since the total bulk is lessened so as not to add to the bulk of the endotracheal tube as it is passed over the introduce! 1.
- the wires in the monitor connector 12 extend a predetermined distance and terminate at a USB or other type of connector to be plugged in to the monitor controller 13 as desired to operate the camera 6 and the light source 7 to display images.
- a wired connection between the monitor connector 12 and the monitor controller 13 can be replaced with a wireless link.
- a wireless transceiver is disposed within the monitor connector 12 or is connected to it. Once connected, power and control signals are provided to the camera 6 and the light source 7 by the wireless connector 12 and the wireless transceiver sends signals indicative to the camera images to the monitor controller 13 having a corresponding wireless transceiver which also communicates with the wireless transceiver disposed in the monitor connector 12.
- monitor controller 13 can be computing device.
- a computing device may be a dedicated device such as shown in the preferred embodiment or alternatively may be a personal computer, a laptop or portable computer, a tablet computer or a modern cellular telephone with smartphone capabilities. So far as the introducer 1 is only used for a relatively short period of time to navigate a path through the glottis, significant computing device power supplies are not required.
- the light source 7 may be longitudinally off-set away from the insertion tip 5 to prevent directly emitted light being received by the camera 6.
- the camera 6 may be physically shielded from the light source 7 within the introducer body 2.
- the introducer connector 8 and the monitor connector 12 Whilst a mechanical arrangement is provided to releasably connect the introducer connector 8 and the monitor connector 12, it will be appreciated that these may connect in an interference fit or a magnetic arrangement. Most preferably, the connectors are self-aligning so that they can only be connected in one configuration which is encouraged through movement of the monitor connector 12 relative to the introducer connector 8.
- the light source 7 may be replaced with one or more optical fibres if desired.
- the camera 6 can be replace by an optical fibre camera which extends from the insertion tip 5 to the introducer connector 8 and which couples optically to corresponding connections in the monitor connector 12.
- the use of optical fibres may further simplify the introducer 1 and may also reduce the cost of production.
- the introducer body 2 can include a conduit extending from the manipulation end 4 to the insertion tip 5 to provide a channel therethrough.
- a conduit extending from the manipulation end 4 to the insertion tip 5 to provide a channel therethrough.
- weights may be placed at one or more points on the outside of the introducer body 2. These weights allow the introducer body 2 to behave more as desired by a practitioner.
- a stiffening wire may be longitudinally disposed within the introducer body 2 and extending along part or all of the introducer body 2.
- a wire or fibre 16 is embedded in the body 2.
- the wire or fibre 16 is anchored at one end 17 at or adjacent the insertion tip 5 within the body 2.
- the wire 16 extends within the body 2 substantially parallel to a body longitudinal axis 18 and is radially off-set therefrom.
- the wire or fibre 16 extends through the body 2 at the manipulation end 4 to allow it to be placed under tension by a user of the introducer 1.
- the anchored end 17 is caused to bend way from the body longitudinal axis towards the wire or fibre 16.
- the wire or fibre 16 is formed from an inert metal or alloy, or is formed from a plastics material. Of course, any natural or synthetic fibre may be used as desired.
- Fig. 3 shows one wire or fibre 16, it will be appreciated any number of spaced apart wires or fibres 16 can be used.
- a pair of wires or fibres 16 can be disposed on opposing sides of the body 2. In this way, the insertion end 3 can be bent about the body longitudinal axis 18 towards one of the wires or fibres 16 when one of the wires or fibres 16 is tensioned.
- a third, fourth or subsequent spaced apart wires or fibres 16 can be disposed in the body 2 off-set from the body longitudinal axis 18. These wires or fibres 16 need not be symmetrically disposed about the body longitudinal axis 18.
- the wire or fibre 16 extends from the body 2 at the manipulation end 4.
- the wire or fibre 16 extends a predetermined distance from the end 4 and terminates at a handle or arrangement 19 (eg loop, etc) to allow the practitioner to clasp a wire or fibre 16 and tension it whilst holding the body 2 about the
- Fig. 4 there is shown a schematic cut-away side view of part of a system 20 incorporating an introducer 1 according to a third preferred embodiment.
- the monitor connector 12 used in the form of a cap that is received over the manipulation end 4 of the introducer 1.
- the monitor connector 12 includes a plurality of electrical wires 15 configured to power and control both the camera 6 and light source 7.
- the monitor connector electrical wires 15 terminate within the monitor connector 12 at electrical contacts 22 and 23.
- the contacts from the lower group of wires 15 are denoted numeral 23 and the wires from the upper group of monitor connector electrical wires 15 terminate at contacts 22.
- the contacts 22 and 23 are in the form of circumferentially disposed strips or bands that are longitudinally spaced apart. This can be best seen in Fig. 5A which shows a cut-away view through the monitor connector 12 of the system 20.
- Fig. 6 there is shown a close up cut-away side view of the manipulation end 4 of the introducer 1 in the system 20.
- the wires 11 extending from the camera 6 and light source 7 terminate at contacts 9 in the form of circumferentially disposed strips or bands that are longitudinally spaced apart.
- Figs 4-6 shows the monitor contacts 22 and 23 corresponding to wiring for the camera 6 and light source 7 respectively being longitudinally spaced apart. This is best shown in Figs 5B & C schematically showing the contact 22 & 23 layout within the monitor connector 12. However, it will be appreciated that any arrangement of monitor contacts 22 and 23 can be provided for electrical engagement with introducer contacts 9.
- any earth or ground contacts may be placed towards an opening (not illustrated clearly) of the monitor connector 12 so that only live contacts are formed once the monitor connector 12 is substantially received the introducer manipulation end 4 and corresponding contacts 9 are substantially in position.
- the opening of the monitor connector 12 may have a slight taper for receiving the manipulation end 4 of the introducer 1 in a light interference fit.
- the opening of the monitor connector 12 may include an electrical switch 27 triggered by the manipulation end 4. The switch 27 is actuated upon insertion of the manipulation in 4 into the monitor connected 12 a sufficient distance. In this way, the contacts 22 and 23 can be configured not to be electrically active unless properly connected to the manipulation end 4 of the introducer 1. Of course, such a switch may only be needed to actuate contacts 22 or 23 that provide electrical power to the camera 6 and light source 7.
- the light source 7 is in the form of one or more optical fibres or waveguides.
- the optic fibre light source 7 in this embodiment extends from the insertion tip 5 at the insertion end 3 within the introducer 1.
- the optic fibre light source 7 terminates at or adjacent the manipulation end 4.
- the monitor connector 12 does not include electrical wires 15 for powering the light source 7 but instead includes a coupling 24 to an optical light source (not illustrated). In this way, the monitor connector 12 attaching to the manipulation end 4 causes optical coupling between a light source or light guide providing light via the monitor connector 12 and the light source 7 at the manipulation end 4.
- the camera 6 has been replaced by a bundle of optical fibres extending from the insertion tip 5 within the introducer I to the manipulation end 4.
- the optic fibre bundle 6 is coupled with a camera and wire 25 or waveguide device 25 (leading to a camera, not illustrated) disposed within the monitor connector 12 in place of electrical wires 1 1.
- the introducer 1 may be able to be created more economically and possibly as a disposable device since the optical coupling for the light source 7 and the optical fibre bundle 6 can be disposed within the monitor connector 12.
- Fig. 7 shows an optical fibre bundle 6 and optic fibre light 7
- the introducer 1 may have either or both bundle 6 and light 7 formed from optic fibres.
- an optically transparent prophylactic may be used to receive the introducer 1 and provide a sealed environment.
- the prophylactic need not be optically clear except at a tip end to which the insertion tip 5 of the introducer 1 is disposed adjacent to or contiguous with in use.
- the prophylactic can be formed from any preferred material such as latex or vinyl.
