Definitions
- the present invention relates to medical devices, in particular an accessory for intubation devices to aid in the positioning and evaluation of the intubation devices.
- an artificial airway for example an endotracheal tube
- This placement can be particularly difficult in irregular circumstances such as with local injury, unusual patient physicality and emergency situations in general.
- Being able to accurately visualize and identify the tracheal opening is a critical step in proper artificial airway placement. In many situations, if the artificial airway is not both accurately and quickly positioned, an undesirable outcome may occur.
- intubation tools such as video laryngoscopes and video stylets are known and used, their expense limits their availability and they are not commonly a part of intubation kits. It is not uncommon, even in hospital settings that such tools are not readily available at the point of care rather such tools must be requested from another part of the hospital where stored or last in use.
- Intubation tools commonly found in an intubation kit include: a laryngoscope handle with sized blades; endotracheal tubes (ETT); supra-glottal artificial breathing devices such as a laryngeal mask, laryngeal tube (e.g. King LT as it is known in the U.S.); stylets; tracheal introducers; an inflation syringe; and other common items such as face masks, catheters, etc.
- ETT endotracheal tubes
- supra-glottal artificial breathing devices such as a laryngeal mask, laryngeal tube (e.g. King LT as it is known in the U.S.); stylets; tracheal introducers; an inflation syringe; and other common items such as face masks, catheters, etc.
- the present invention relates to an accessory for intubation devices to aid in the positioning and continued evaluation thereof.
- the continued evaluation can refer to cases where patients have long-term artificial breathing care and it is thus important to determine that the intubation tube remains in its proper location and in proper condition.
- POC point of care
- an intubation tube accessory for use in combination with an intubation tool.
- the intubation accessory includes: an illumination member; an imaging device with which the illumination member is associated; a communication mechanism operably connected to the imaging device and configured to convey images from the imaging device to a display screen; and an intubation tool fixing mechanism configured for removable fixing of the intubation accessory to the tool.
- the intubation tool fixing mechanism includes a generally cylindrical shape. In some embodiments, the intubation tool fixing mechanism includes at least one outwardly extending projection. In some embodiments, the intubation tool fixing mechanism includes a threaded portion. In some embodiments, the intubation tool fixing mechanism includes at least one spring. In some embodiments, the intubation tool fixing mechanism includes a foam sleeve. In some embodiments, the intubation tool fixing mechanism includes a set (kit) of tool fixing members.
- the accessory further includes a carbon dioxide sensor to assist intubation.
- the imaging device includes a video camera.
- the image is communicated via a fiber optic tube or the like to the imaging device, which can thereby be positioned outside the patient's body.
- the communication mechanism includes a cable. In some embodiments, the communication mechanism includes a wireless communication system.
- tools and “intubation tool” and their derivatives will be used to include all appropriate intubation related medical devices, including for example various artificial airways (e.g. ETTs (endotracheal tubes) and super-glottic airways as well as positioning devices therefor such as standard laryngoscopes, video and optical laryngoscopes, stylets, optical and video stylets and introducers.
- ETTs endotracheal tubes
- super-glottic airways as well as positioning devices therefor such as standard laryngoscopes, video and optical laryngoscopes, stylets, optical and video stylets and introducers.
- Advantages of the present intubation accessory include:
- FIG. 1 shows an embodiment of an intubation accessory in accordance with the present invention, illustrated in use in conjunction with an intubation tube orally introduced into a patient, and aided by an intubation stylet and a display screen;
- Fig. 3 is a perspective view of the present intubation accessory of
- FIG. 4 is a side view of another embodiment of the intubation accessory in accordance with the present invention, particularly useful for nasal introduction intubation procedures; and [028] Fig. 5 is a side view of another embodiment of the intubation accessory in accordance with the present invention, also particularly useful for nasal introduction intubation procedures.
- the intubation accessory of the present invention will be mainly described in conjunction with an ETT, it should be understood that the present intubation accessory can also be used in conjunction with other artificial airways, for example supra-glottic airway devices that facilitate ventilation without entering the trachea, such as laryngeal masks, laryngeal tubes (known as a King LT in the U.S.) and the like.
- the terms "endotracheal tube", “ETT” and their derivatives will be used herein the description and claims to include other such intubation tubes, including those listed above.
- FIG. 1 shows an embodiment of an intubation accessory 50 in accordance with the present invention in use during oro-tracheal intubation in conjunction with an intubation tube, specifically an endotracheal tube ETT.
- laryngoscopy is commonly performed with a laryngoscope L first placed in a patient's upper airway to mobilize the tongue to assist in exposing the tracheal opening.
- Endotracheal tube ETT is then inserted into the patient's airway and placed so as to provide air/oxygen to the patient, with the aid of a display screen C that is operably attached to intubation accessory.
- a malleable stylet S to pre-form the inherently flexible endotracheal tube ETT to a desired shape for the procedure, as illustrated, or a tracheal introducer N, which is a flexible rod, typically made of plastic having a profile or cross-section similar to a stylet with an optional coude tip that is used to intubate the trachea and serve as a guide over which the ETT is then introduced into position.
- Stylet S can be additionally utilized either as a mount for intubation accessory 50 within the endotracheal tube or to position the intubation accessory at the distal end of the ETT itself for optimal visualization. Following successful intubation, stylet S (or introducer N) is then removed, along with intubation accessory 50, or, the intubation accessory is removed shortly thereafter.
- FIG. 2 shows a detailed view of the present intubation accessory
- Illumination member 12 can be configured as a combination of an illumination source and image capturing/camera lens.
- Image capturing device 10 (including illumination member 12 where applicable) and communication mechanism 14 can be collectively considered as components of a data acquisition unit of intubation accessory 50.
- a fiber optic tube, or the like is configured to be attachable to an intubation tool and communicates with imaging capture device 10, which can thereby be positioned external of the patient.
- fixing mechanism 16 has a generally cylindrical shape defining a tubular cavity 18 configured to receive the distal end of stylet S in order to place intubation accessory 50 onto the end of the stylet (or introducer N), for example.
- fixing mechanism 16 is made of a relatively soft or flexible plastic, or the like, thereby providing some flexible quality to help provide ease and range of fit.
- fixing mechanism 16 of intubation accessory 50 may have a range of sizes to thereby suit ETT's and other artificial airways such as super-glottic airways as well as intubation tools/positioning devices such as stylet S and introducer N of different sizes.
- the outer diameter "D" of fixing mechanism 16 may be dimensioned to facilitate a somewhat snug fit within the ETT, while being reasonably easily removable therefrom; and/or (b) the inner diameter "d" of cavity 18 may be dimensioned to facilitate a similar fit over stylet S or introducer N.
- intubation accessory 50 comes with a kit or set of variously sized and/or type fixing mechanisms 16 to facilitate the above- mentioned fit, as will be understood with respect to embodiments described below.
- FIG. 3 shows another embodiment of intubation accessory 50 in accordance with the present invention, particularly useful for nasal introduction intubation procedures.
- Stylets such as stylet S
- introducers such as introducer N
- intubation accessory 50 must be fixed to the inner wall of the ETT.
- fixing mechanism 16 includes an externally facing ETT interface mechanism, in the present embodiment including at least one and typically a plurality of bendable wings or protrusions 20 protruding from the outside of the fixing mechanism.
- Protrusions 20 are configured to interface with the inner wall of the ETT to thereby help removably fix intubation accessory 50 to thereto.
- Protrusions 20 are illustrated as protruding generally radially outward from fixing mechanism 16, which is a typical embodiment, and as having a nub-like shape, which is a typical configuration; however, should not be considered as limiting as various shapes and angles of protrusion can be used.
- FIG. 4 shows another embodiment of intubation accessory 50 wherein fixing mechanism 16 includes a threaded portion 22 to which an ETT interface component can be attached, such as one or more adjustable leaf-like springs 24.
- Spring 24 can be generally cylindrically shaped and screwed onto threaded portion 22, either already assembled or threaded shortly prior to intubation. Again, such a design is particularly useful for nasal introduction intubation procedures, although threaded portion 22 can also be formed in a cylindrical shape with a cavity, such as cavity 18 so that stylet S or introducer N can be inserted therein. It should be understood that other components having similar function to spring(s) 24 can be used.
- One example of another such component is a foam sleeve 26 (Fig.
- intubation accessory further includes a carbon dioxide sensor 28, which can be useful for helping detect carbon dioxide exiting the trachea and thereby helping identify an altered tracheal opening to assist in the proper placement of the ETT.
- fixing mechanism 16 is preferably configured to be both removably fixed to an ETT as well as mountable on the distal end of a stylet or introducer, and for such purpose the fixing member may have both a cavity as well as protrusions 20 (or threaded portion 22 and/or spring 24 or foam sleeve 26, or the like).
- the intubation accessory 50 will be implemented as a disposable one-time use device.
- the intubation accessory 50 is configured and designed to be sterilized after use so that the accessory is a multi-use device.
