Description

A tracheal intubation guide
The present invention relates to a tracheal intubation guide for guiding, positioning and insertion of e.g. an endotracheal tube in a patients trachea, and where the intubation guide comprises a relatively flexible guide element being attached to the distal end of a relatively stiff, elongated and curved positioning handle, so that it is possible, by manipulating the proximal end of the positioning handle, to insert the guide scoop in the mouth of a patient, and to push the guide scoop down the throat of a patient, and place it in a position under the patients epiglottis and larynx.
Description of related art
Intubation guides of the above mentioned type are well known in many differ- ent embodiments. A common use for such intubation guides is to provide a guide for insertion of e.g. an endotracheal tube into the patient's trachea. In most patients insertion of an endotracheal tube may be readily performed under direct laryngoscopy of the patients vocal cords using a conventional rigid laryngoscope to create e direct line of vision for the person performing the intubation procedure. However, it is not always easy and some times impossible to obtain full vision of the patient's vocal cords with the result that correct insertion of the endotracheal tube is difficult and unreliable.
US patent no. 5287848 discloses one example of an intubation guide an eyepiece arranged for visualization of the vocal cords. The structure of this intubation guide is made from a one piece, hard plastic, structure being difficult to pass gently behind the tongue and underneath the tip of the patient's epiglottis. US patent no. 5038766 discloses another example of such an intubation guide mentioned above, where the positioning handle is made of curved blade member and the guide element is formed as a plug shaped element made from a relatively soft material, and having a central channel, so that the curved blade member can slide the guide element down the throat of the patient until the guide element engages e.g. with the patients epiglottis and thereby resists further insertion of the guide element, when the correct position of the guide element is reached.
A recurring problem when inserting such intubation guides in a patient is that it is difficult, due to either the size of the guide element or to the hard material used for the guide tip, to insert the intubation guide without the risk of causing trauma to the patient.
Summary of the invention The main object of the present invention is therefore to provide a an intubation guide being easy to insert without risk of trauma to the patient
This is obtained according to the present invention as defined in claim 1 , and especially by having the guide element forming a scoop shaped structure as an extension of the positioning handle, and in that the positioning handle comprises an intubation channel extending along the positioning handle, and having a first end near the proximal end of the positioning handle, and the other end at the distal end near the guide scoop. Thereby the flexible guide scoop is easier to slide along the palate, below the root of the tongue of the patient, and below the tip of the epiglottis without the risk of causing trauma to the patient, and when the guide scoop is placed correctly, then the relatively rigid positioning handle provides the possibility of easy manipulation of the distal end of the positioning handle, so that e.g. an endotracheal tube can be slid into the channel and correctly directed to the patients trachea. In a preferred embodiment the intubation channel is open along its entire length on one side, and at the concave side of the curved section of the positioning handle facing the patients tongue and epiglottis when the intubation guide is inserted correctly in a patient. Thereby it is easy to remove the intubation guide after having inserted e.g. the endotracheal tube correctly.
In a preferred embodiment the flexible guide scoop forms an extension of the distal end of the positioning handle and extends at least from the convex side of the intubation channel facing away from the patients epiglottis when the intubation guide is inserted correctly in a patient, and so that the channel end at the distal end of the positioning handle is placed on one side of the scoop facing the epiglottis when the intubation guide is inserted correctly in a patient.
In this relation the flexible scoop may preferably comprise a substantially flat and flexible plate or sheet having an outer periphery, and in that the outer periphery comprises a flexible flange, a flexible inflated or inflatable tube or another flexible means arranged and adapted for stabilizing the flexible plate or sheet.
Furthermore in a preferred embodiment the flexible scoop or the positioning handle comprises at least one wedge portion that forms an extension of the distal end of the positioning handle, and where the wedge portion has its wedge point pointing away from the positioning handle. Thereby it is easy to pass the flexible guide scoop under the patients epiglottis, as the wedge portion engages the epiglottis and lifts the epiglottis upwardly in the throat of the patient, so that a free view of the vocal cords and an unrestricted passageway for e.g. an endotracheal tube is provided. The intubation guide according to the invention is very suitable for video assisted guiding of e.g. an endotracheal tube. In this relation a preferred embodiment comprises a second channel extending at least partly along the positioning handle and having one end being placed close to the end of the intubation channel placed at the distal end of the positioning handle.
In this relation the second channel may preferably form a tube at least at its end closest to the distal end of the positioning handle, and having an optical window arranged for closing the end of the tube at the distal end of the posi- tioning handle, and where the tube and the optical window be arranged such that it allows an imaging device like an endoscopic video device to be inserted into the tube, and be positioned so that it can provide images of the area on the side of the flexible scoop facing a patients epiglottis, when the intubation guide is correctly inserted in a patient.
The positioning handle may further comprise a third channel extending at least partly along the positioning handle and having an open end being placed close to the end of the intubation channel placed at the distal end of the positioning handle. This facilitates the use of other instruments, such as e.g. a surgical instrument without obstruction of the other channels.
In a preferred embodiment the positioning handle comprises an extension from the proximal end of the positioning handle, so that easy manipulation of the positioning handle is obtained.
Due to its structural simplicity the intubation guide according to the invention is especially advantageous as a disposable unit. In this relation it is especially advantageous when the handle is made from a relatively hard plastic material, and the scoop is made from a relatively soft plastic material, and where the scoop is attached to the positioning handle by gluing , welding or moulding. Brief description of the drawings
In the following, the invention will be described in greater detail with refer- ence to embodiments shown by the enclosed figures. It should be emphasized that the embodiments shown are used for example purposes only and should not be used to limit the scope of the invention.
Figure 1 shows an intubation guide according the invention fitted with an en- doscopic video device.
Figure 2 is an enlarged view of the guide scoop on the intubation guide shown in fig. 1. Figure 3 shows the intubation guide shown in fig. 1 seen from one side, and with an unflexed guide scoop.
Figure 4 shows the intubation guide shown in fig. 1 seen from one side, and with a flexed guide scoop.
Figure 5 shows a cross section of one embodiment of the intubation guide according to the invention seen at along the line A - A on fig. 3.
Figure 6 shows an alternative cross section of a second embodiment of the intubation guide according to the invention.
Figure 7 shows an alternative embodiment of the flexible guide scoop.
Detailed description of the embodiments Figure 1 shows one embodiment of an intubation guide 1 according to the present invention being equipped with an endoscopic video device comprising a display unit 2, and a video camera being placed in the intubation guide 1 and connected to the display unit 2 via the wiring 3.
Although an intubation guide according to the invention is especially advantageous for use with endoscopic video systems it may, however, also be used without such a device. The figures 2 to 5 shows different details of the intubation guide according to figure 1. The Intubation guide 1 has a guide scoop 4 arranged on the distal end 5 on the positioning handle 6. This guide scoop is in this embodiment a flat plate or sheet 7 that is made form a flexible material, and along its periphery it is stabilized by means of an inflated tube 8, so that it forms a flexi- ble scoop shaped structure having a size and flexibility that facilitates that the guide scoop can be inserted into the throat of a patient by flexing the guide scoop so that it easily slides e.g. along the patients palate 16, below the root of the tongue and below the tip of epiglottis with a minimum of risk of creating trauma to the patient. As an example fig. 4 shows the guide scoop being flexed against the patient's palate but it is evident that the flexible guide scoop is flexible in many other directions, but is able to return to its original shape due to the inflated tube 8.
For the purpose of providing easy manipulation of the intubation guide, then the proximal end 19 of the intubation guide is provided with an extension 20.
On the upper side of the guide scoop 4 is arranged a ramp 9 forming a wedge portion 9 extending from the distal end 5 of the positioning handle 6 and forward in extension of the distal end 5. This wedge portion 9 has the function of pushing the epiglottis aside when the guide scoop 4 is slid behind or under the patient's epiglottis, so that an unrestricted passage to the patient's trachea is obtained.
The positioning handle 6 is made of a relatively hard plastic material and comprises an intubation channel 11 that serves as a conduit for insertion of e.g. an endotracheal tube (not shown), and thereby it is possible to use the positioning handle to manipulate the tracheal tube into the patients trachea when the intubation guide is correctly inserted in a patient, by pushing the endotracheal tube in the channel to extend from the distal end 5 of the positioning handle 6, and steering the endotracheal tube into the trachea of the patient.
The intubation channel 11 is open on one side namely the convex side 2 of the curved positioning handle 6, and this convex side will, when the intubation guide rest against the tongue, so that the tongue closes the intubation channel 11 and thereby ensures that the endotracheal tube stays in the intubation channel 11 when it is slid down via the channel 11.
After having inserted the endotracheal tube into the patient, then the open side of the intubation channel 11 allows that the intubation guide 1 can be removed from the patient without substantial manipulation of the endotracheal tube.
Fur the purpose of avoiding that the tongue closes the channel a flange 12 is arranged on each side of the opening in the intubation channel 11.
Next to the intubation channel 11 is arranged a second channel 13 as seen especially on fig. 5 for the insertion of a endoscopic video camera, and at the distal end of the positioning handle 6 is arranged a window for closing the end at the second channel. As shown in fig. 6 a third channel may also be provided in an alternative embodiment, where this channel may provide the possibility of inserting other instruments into the patient via the intubation guide. It will be evident to the skilled person that the present invention may be realized in other embodiments than the one discloses in figures 1 to 4. As an example of this fig. 9 shows another embodiment of an intubation guide, where the plate or sheet 7 is stabilized by a flange 18 in stead of the inflated tube 8 according to figures 1 to 4. In this embodiment the wedge 9 shown on the figures 1 to 4 is integrated in the flange 18 on figure 7.
