BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates, in general, to intubation devices and methods. Description of the Related Art

Intubation is the operation of inserting a tube into an animal's hollow organ or body passage to keep the organ or body passage open. One common example of intubation is endotracheal intubation, wherein a breathing tube is placed within the trachea of an animal. While endotracheal intubation will be described herein for sake of clarity, it is to be understood that the teachings herein are not limited to endotracheal intubation, but may instead be extended to other types of intubation.

The operation of endotracheal intubation may be described as follows. First, a patient's head is positioned, and mouth is opened, to allow a straight line of access from the mouth to the vocal cords (e.g., by placing a pillow under the head and neck of the patient). Second, the blade of a laryngoscope (a device which typically consists of a blade, a light source, and a handle) is introduced into the right-hand side of the patient's mouth, and the blade is used to sweep the tongue to the left. Third, the blade is advanced until the right tonsil is reached, at which point the health care provider sweeps the blade toward the midline of the patient's body ~ this brings the patient's epiglottis into view. Fourth, the health care provider advances the laryngoscope blade until it reaches the base of the epiglottis. Fifth, the health care provider levers the laryngoscope such that the epiglottis is moved toward the top of the patient's head such that the vocal cords of the patient come into view. Sixth, the health care provider advances the endotracheal tube through the vocal cords, until the inflatable cuff of the endotracheal tube has traversed the patient's vocal cords. Seventh, the health care provider inflates the inflatable cuff of the endotracheal tube which holds the endotracheal tube in the patient's trachea. Eighth, the health care provider secures the endotracheal tube somewhere inside the patient's mouth (typically, to the patient's upper jaw), and the operation of endotracheal intubation is considered completed.

DETAILED DESCRIPTION OF THE INVENTION

With reference to the figures and with reference now to Figure 1 A, shown is a side-plan view of an intubation-tube placement device 100 secured to an intubation tube 116. In one implementation, the intubation-tube placement device 100 is secured to the intubation tube 116 by a retaining device in contact with the intubation tube 116. Illustrated is that, in one implementation, the retaining device in contact with the intubation tube 1 16 is characterized by a rubber stopper (or grommet) 118, where the rubber stopper 118 has a hole through which the intubation-tube placement device 100 has been inserte . Shown is that, in one implementation, the rubber stopper 118 is affixed to the intubation tube 116 via mechanical friction, which allows rubber stopper 118 to be severed from the intubation tube 116 via either a simple twisting or pulling motion. That is, in one implementation, the health care provider grasps the intubation tube 116 with one hand, grasps the rubber stopper 118 and intubation-tube placement device 100 with the other hand, and pulls the intubation tube 116 and the rubber stopper 118 in opposite directions such that the rubber stopper 118 breaks away from the intubation tube 116 so that the rubber stopper 118 and the intubation-tube placement device 100 may be removed from the intubation tube 116. Referring now to Figure IB, shown is that another implementation of an intubation-tube placement device 100 secured to an intubation tube 116 is characterized by an intubation-placement-device guide 120 integral with the intubation tube 116, where the intubation-placement-device guide 120 has a hole through which the intubation-tube placement device 100 has been inserted. Illustrated is that, in one implementation, the intubation-placement-device guide 120 is affixed to the intubation tube 116 via a breakaway perforated border 122, which allows the intubation-placement-device guide 120 to be severed from the intubation tube 116 via either a simple twisting or pulling motion. That is, in one implementation, the health care provider grasps the intubation tube 116 with one hand, grasps the intubation-placement-device guide 120 and the intubation-tube placement device 100 with the other hand, and twists the intubation tube 116 and the intubation-placement-device guide 120 in opposite directions such that the intubation- placement-device guide 120 breaks away from the intubation tube 116 so that the intubation-placement-device guide 120 and the intubation-tube placement device 100 may be removed from the intubation tube 116.

In various implementations, an intubation-tube placement device (e.g., intubation-tube placement device 100) is a semi-rigid structure constructed from a material having a relatively low coefficient of friction, so that the intubation-tube placement device 100 may be relatively easily slid back and forth through the hole of a retaining device (e.g., rubber stopper 1 18 or intubation-placement-device guide 120). In one implementation, this is achieved by forming the intubation-tube placement device from a medical-grade polymeric material, such as medical-grade polyvinyl chloride (PVC) or medical-grade nylon.

In various implementations, an intubation-tube placement device (e.g., intubation-tube placement device 100) is a semi-rigid structure constructed from a material which is malleable and which has a memory quality sufficient to permit a health care provider to manipulate the intubation-tube placement device into a shape or form according to the health care provider's preference. The material is malleable enough to allow the health care provider to relatively easily bend the intubation-tube placement device, and the memory quality is such that, subsequent to the health care provider's bending the intubation tube placement device into any particular shape, the intubation-tube placement device will tend to maintain both itself and an intubation tube (e.g., intubation tube 116), to which the intubation-tube placement device is secured, during use of the intubation- tube- placement device secured to the intubation tube. The inventor believes that health care providers will find such construction particularly attractive in that such health care providers can easily personalize the device to their use preferences. In one implementation, this is achieved by forming the intubation-tube placement device from a medical-grade, reinforced, polymeric material, such as medical-grade reinforced polyvinyl chloride (PVC) or medical-grade reinforced nylon. However, those skilled in the art will appreciate that other materials may be found suitable via a reasonable amount of experimentation in light of the teachings herein.

In various implementations, an intubation-tube placement device (e.g., intubation-tube placement device 100) is a semi-rigid structure having either a cross section appropriate to an adult or a cross section appropriate to a child. In one implementation, the cross section appropriate to a neonatal premature infant is a cross section whose widest point is no greater than .05 ("point zero five") mm. In another implementation, the cross section appropriate to a child is a cross section whose widest point is no greater than .5 ("point five") mm. In another implementation, the cross section appropriate to an adult is a cross section whose widest point is no greater than 6.0 ("six point zero") mm. In another implementation, the intubation-tube placement device (e.g., intubation-tube placement device 100) is a semi-rigid structure having a cross section appropriate to a veterinary animal (e.g., a horse, a cow, a monkey, a dog, a guinea pig, a mouse, a rat, etc.). In one implementation, the cross section appropriate to a veterinary animal is a cross section whose widest point is no greater than 10.0 ("ten point zerd' ) mm. Those skilled in the art will recognize that the cross sections listed herein are merely exemplary and that many other cross sections can be used dependent upon the patient undergoing intubation and health care provider preference.

As shown herein, the intubation-tube placement device is depicted as a cylindrically-shaped rod. Those having ordinary skill in the art will appreciate that the intubation tube placement device can have many other shapes such as an octagonal shape, an ellipsoid shape, or a square shape. With reference now again to Figures 1A and IB, illustrated is that an anti- perforation device 102 is coupled to an intubation-tube placement device 100. In one implementation, the anti-perforation device 102 is characterized by an internal light source, which aids the health care provider in placing the intubation-tube placement device 100 (e.g., by illuminating the vocal cords of a patient); in one implementation, the internal light source contains its power source, while in another implementation it is powered via an externalized battery pack via wires (not shown) running through the length of the intubation-tube placement device 100. In another implementation, the anti-perforation device 102 is characterized by a channel which articulates with a channel of the intubation- tube placement device 100 whereby suction can be applied via the anti-perforation device 102. For example, in one implementation, the anti-perforation device 102 has a hole drilled all the way through it, and the intubation-tube placement device 100 is a hollow tube; the anti -perforation device 102 is affixed to the intubation-tube placement device 100 such that the hole aligns with the hollow tube, thereby forming one continuous channel which will support a vacuum and thus allow the health care provider to apply suction through the anti-perforation device 102. With respect to the aspect of suctioning, in another implementation, the intubation-tube placement device 100 forms a hollow tube, and there is no anti -perforation device 102 is coupled to the intubation tube placement device, in which case suction is directly applied via an open end of the hollow tube formed by the intubation-tube placement device 100.

Continuing to refer to Figures 1A and IB, shown is that, in one implementation, tactile-accentuator flaps 114 are coupled to intubation-tube placement device 100. Illustrated is that, in one implementation, each of the tactile-accentuator flaps 114 forms a non-zero angle with an axis of the intubation-tube placement device 100 (e.g., a 90 degree angle such as is shown in Figures 1 A and 1 B). In one embodiment, the tactile- accentuator flaps 114 are affixed to a ring-like structure encompassing the intubation-tube placement device 100. In another embodiment, the tactile-accentuator flaps 114 are directly affixed to the anti-perforation device 102. The inventor points out that while tactile-accentuator flaps 1 14 are illustrated herein as extending from the body of the intubation-tube placement device 100 and beyond the outermost portions of the anti- perforation device 102, in other contemplated embodiments the tactile-accentuator flaps 114 extend no further from the body of the intubation-tube placement device (100) than the outermost portions of the anti-perforation device 100, thereby allowing the health care provider a more clear line of sight to the patient's vocal cords.

The inventor has found that the retaining device (e.g. rubber stopper 118 or intubation-placement-device guide 120) serves as a "handle" for the intubation-tube placement device 100. That is, the inventor has found that the retaining device "amplifies" the physical motion of the proximate end (e.g., the end to which the anti-perforation device 102 is affixed) of the intubation-tube placement device 100, making it easier to intubate a patient in the absence of the handle. In addition, while the retaining device is treated as the handle for the sake of illustration herein, in another contemplated embodiment, a handle is actually affixed to the intubation-tube placement device 100, while in another contemplated embodiment the handle is actually affixed to the intubation tube 116.

Referring now to Figure 2, depicted is a side-plan isolation view of an anti- perforation device 102 coupled to an intubation-tube placement device 100. Illustrated is that, in one implementation, the anti -perforation device 102 is characterized by the light source internal to the anti-perforation device 102 (illustrated in Figure 2 via light rays emanating from the anti-perforation device 102). Shown is that the anti-perforation device 102 has a trailing portion 104 and an exploratory portion 106. Depicted is that, in one implementation, the exploratory portion 106 of the anti -perforation device 102 has a spheroid shape, where lines drawn tangent to the spheroid shape would typically form an oblique angle with the axis of the intubation-tube placement device 100. Further depicted is that, in one implementation, a portion of the spheroid shape extends beyond the outer diameter of the intubation-tube placement device 100, which the inventor has found particularly advantageous in preventing perforation of internal body structures. In one implementation, the spheroid shape proves particularly advantageous in that it serves to protect the internal structures of a patient undergoing intubation.

With reference now to Figure 3A, shown is a side-plan isolation view of an alternate embodiment of an anti-perforation device 102 coupled to an intubation-tube placement device 100. Depicted is an open channel 300 between the trailing portion 104 and the exploratory portion 106 of the anti-perforation device 102. Illustrated is that, in one implementation, the intubation-tube placement device 100 forms a hollow tube. Shown is that the trailing portion 104 of the anti -perforation device 102 is coupled to the intubation-tube placement device 100 such that the channel 300 of the anti-perforation device 102 substantially aligns with the hollow tube formed by the intubation-tube placement device 100, thereby forming a suctioning tube. Depicted is that, in one implementation, the exploratory portion 106 of the anti-perforation device 102 has a ellipsoid shape, where lines drawn tangent to the ellipsoid shape would typically form an oblique angle with the axis of the intubation-tube placement device 100. Further depicted is that, in one implementation, a portion of the ellipsoid shape extends beyond the outer diameter of the intubation-tube placement device 100, which the inventor has found particularly advantageous in preventing perforation of internal body structures.

Referring now to Figure 3B, depicted is a side-plan isolation view of an alternate embodiment of an anti -perforation device 102 coupled to an intubation-tube placement device 100. Illustrated is an open channel 300 between the trailing portion 104 and the exploratory portion 106 of the anti-perforation device 102. Shown is that, in one implementation, the intubation-tube placement device 100 forms a hollow tube. Depicted is that the trailing portion 104 of the anti-perforation device 102 is coupled to the intubation-tube placement device 100 such that the channel 300 of the anti -perforation device 102 substantially aligns with the hollow tube formed by the intubation-tube placement device 100, thereby forming a suctioning tube. Depicted is that, in one implementation, the exploratory portion 106 of the anti-perforation device 102 has a spheroid shape, where lines drawn tangent to the spheroid shape would typically form an oblique angle with the axis of the intubation-tube placement device 100. Further depicted is that, in one implementation, a portion of the spheroid shape extends beyond the outer diameter of the intubation-tube placement device 100, which the inventor has found particularly advantageous in preventing perforation of internal body structures.

With reference now to Figure 3C, illustrated is a side-plan isolation view of an alternate embodiment of an anti-perforation device 102 coupled to an intubation-tube placement device 100. Shown is that, in one implementation, the anti-perforation device 102 has a spheroid shape formed from solid surfaces arranged in various angles. Depicted is that, in one implementation, the exploratory portion 106 of the anti -perforation device 102 has an angled shape, where lines drawn tangent to the angled shape would typically form an oblique angle with the axis of the intubation-tube placement device 100. Further depicted is that, in one implementation, a portion of the angled shape extends beyond the outer diameter of the intubation-tube placement device 100, which the inventor has found particularly advantageous in preventing perforation of internal body structures. While the exploratory portion 106 of the anti-perforation device 102 has been shown in Figures 2-3 C as having a fixed structure, in one contemplated embodiment the exploratory portion 106 of the anti-perforation device 102 is formed from a medical- grade room-temperature malleable material (e.g., a medical-grade polymer or wax) which can be manipulated into a shape chosen by the health care provider performing intubation. For example, the anti -perforation device 102 could come prepackaged in a spherical shape, which the health care provider could then manipulate as he sees fit. In addition, in one contemplated embodiment the anti-perforation device 102 comes prepackaged with a lubricant coating the anti-perforation device 102.

Referring now to Figure 4A, shown is a front-plan view of an anti- perforation device 102 coupled to an intubation-tube placement device 100. Depicted is that, in one implementation, the intubation-tube placement device 100 has a cylindrical shape. In one implementation, the intubation-tube placement device 100 forms a hollow tube, while in another implementation, the intubation-tube placement device 100 forms a solid rod. With reference now to Figure 4B, depicted is a front-plan view of an anti- perforation device 102 coupled to an intubation-tube placement device 100. Illustrated is that, in one implementation, the intubation-tube placement device 100 has an octagonal shape. In one implementation, the intubation-tube placement device 100 forms a hollow tube, while in another implementation, the intubation-tube placement device 100 forms a solid rod.

Referring now to Figure 5, shown is a side-plan view of tactile-accentuator flaps 114 coupled to an intubation-tube placement device 100. Illustrated is that, in one implementation, each of the tactile-accentuator flaps 114 forms a non-zero angle with an axis of the intubation-tube placement device 100. Shown is that, in one implementation, the tactile-accentuator flaps 114 are affixed to a ring-like structure 116 encompassing the intubation-tube placement device 100. Depicted is that, in one implementation, the tactile- accentuator flaps 114 are proximate to the anti-perforation device 102, which is itself coupled to the intubation-tube placement device 100. In another implementation, not shown, the tactile-accentuator flaps 114 are directly coupled to the anti -perforation device 102. With reference now to Figure 6A, depicted is a side-plan isolation view of an alternate implementation of tactile-accentuator flaps 114 coupled to an intubation-tube placement device 100. Illustrated is that, in one implementation, each of the tactile- accentuator flaps 114 forms a non-zero angle with an axis of the intubation-tube placement device 100. Shown is that, in one implementation, the tactile-accentuator flaps 114 are affixed to a ring-like structure 116 encompassing the intubation-tube placement device 100. Depicted is that, in one implementation, the tactile-accentuator flaps 114 are proximate to the anti-perforation device 102 coupled to the intubation-tube placement device 100. In another implementation, not shown, the tactile-accentuator flaps 114 are directly coupled to the anti-perforation device 102. Referring now to Figure 6B, illustrated is a side-plan isolation view of an alternate implementation of tactile-accentuator flaps 114 coupled to an intubation-tube placement device 100. Shown is that, in one implementation, each of the tactile- accentuator flaps 114 forms a non-zero angle with an axis of the intubation-tube placement device 100. Depicted is that, in one implementation, the tactile-accentuator flaps 114 are directly affixed to the anti-perforation device 102. Illustrated is that, in one implementation, the tactile-accentuator flaps 114 are proximate to the anti-perforation device 102 coupled to the intubation-tube placement device 100. In another implementation, not shown, the tactile-accentuator flaps 114 are directly coupled to the intubation-tube placement device 100. With reference data Figure 6C, shown is a side-plan isolation view of an alternate implementation of tactile-accentuator flaps 114 coupled to an intubation-tube placement device 100. Shown is that, in one implementation, each of the tactile- accentuator flaps 114 forms a non-zero angle with an axis of the intubation-tube placement device 100. Depicted is that, in one implementation, the tactile-accentuator flaps 114 are directly affixed to the anti-perforation device 102. Illustrated is that, in one implementation, the tactile-accentuator flaps 114 are proximate to the anti-perforation device 102 coupled to the intubation-tube placement device 100. In another implementation, not shown, the tactile-accentuator flaps 114 are directly coupled to the intubation-tube placement device 100.

In various implementations, a tactile-accentuator flap (e.g., one of the tactile-accentuator flaps 114) is a semi-rigid structure constructed from a material having a relatively low coefficient of friction, so that the tactile-accentuator flaps may be relatively easily slid back and forth across the internal structures of the body (e.g., the cartilaginous rings lining the trachea of an animal). In one implementation, this is achieved by forming the tactile-accentuator flap from a medical-grade polymeric material, such as medical- grade polyvinyl chloride (PVC) or medical-grade nylon. The inventor has discovered that the tactile accentuator flaps are particularly useful in performing intubations in that the tactile accentuator flaps allow the intubating health-care provider to detect the cartilaginous rings lining the trachea, by amplifying the tactile impressions generated by such cartilaginous rings. The inventor has discovered that such tactile amplification increases the likelihood that an intubation tube will be placed in the trachea of a patient rather than the esophagus of the patient.

Referring now to Figures 7A and 7B, shown are structures substantially analogous to those depicted in Figures 4A and 4B, to which have been affixed tactile- accentuator flaps 114. Depicted is that, in one implementation, each of the tactile- accentuator flaps 114 presents in front-plan view as having a 1 mm by 1 mm facial profile. The inventor has found that it is advantageous that the tactile-accentuator flaps 114 be thin enough to permit flexing and bending in their profiles; exactly how thin the tactile- accentuator flaps 114 will be will vary in application dependent upon the materials used and can be determined empirically via a reasonable amount of experimentation. However, while various sizes and shapes of the tactile-accentuator flaps 114 have been illustrated and described herein, those skilled in the art will appreciate that other sizes and shapes of facial profiles can be utilized in light of the teachings herein via a minimal amount of experimentation.

Those skilled in the art will appreciate that while Figures 5-7B depict only two tactile-accentuator flaps 114, the teachings herein are not limited to only two flaps and that other numbers of tactile-accentuator flaps 114 are possible (e.g., one, three, four, five, etc.).

With reference now to Figure 8, depicted is an isolated perspective view of an intubation-tube placement device 100 secured to an intubation tube 116. Illustrated is the intubation-tube placement device 100 held internal to the intubation tube 116 via a retaining device in contact with the intubation tube 116. Shown is that, in one implementation, the retaining device is a rubber stopper 118 having a hole 140, which runs the length of the rubber stopper 1 18, through which intubation-tube placement device 100 has been inserted. Depicted is that, in one implementation, the rubber stopper 118 holds the intubation-tube placement device 100 internal to the intubation tube 116 via mechanical friction.

Referring now to Figure 9, shown is a perspective view of an intubation tube 116, an intubation-tube placement device 100, and a rubber stopper 118 in disassembled form. With reference now to Figure 10, depicted is a top-plan view of three different-sized implementations of a rubber stopper 118, and an intubation-tube placement device 100. As has been described, varying sizes of the intubation-tube placement device 100 can be used depending upon the needs of the patient undergoing intubation and/or preferences of the health-care provider performing intubation. Referring now to Figure 11 , illustrated is a side-plan view of an intubation- tube placement device 100 internal to intubation tube 116. Shown is that the intubation- tube placement device 100 has coupled to it an implementation of the anti-perforation device 120.

With reference now to Figure 13, shown is a perspective view of an intubation-tube placement device 100 internal to a modified intubation tube 1300. Shown is the modified intubation tube 1300 has a rounded tip 1302, which is different from the beveled tip of intubation tube 1 16. The inventor has empirically determined that the rounded tip 1302 of the intubation tube 1300 is particularly advantageous.

Referring now to Figure 14, depicted is a perspective isolation view of the rounded tip 1302 of the intubation tube 1300. With reference now to Figure 15, illustrated is a perspective view of an intubation-tube placement device 100 internal to a modified intubation tube 1300. Shown coupled to intubation-tube placement device 100 is an implementation of an anti- perforation device 102. Referring now to Figure 16, shown is a perspective isolation view of an alternate implementation of the modified intubation tube 1300. Depicted is a rounded and tapered tip 1600 having open slots, or ports, 1306 which allow for ventilation of an intubated patient.

Although not explicitly shown, it is to be understood that in most implementations the modified intubation tube 1300 will have inflatable cuffs on them to allow proper oxygenation and ventilation of intubated patients.

Those having ordinary skill in the art will recognize that national hospital accreditation standards have recently prohibited intubation (e.g., endotracheal) tubes from being opened before use. The practical effect of such standards is that now that all health care providers performing intubation must first open a medical-grade sterile package, insert a metal stylet into the endotracheal tube, and bend both to the desired shape before intubating. Accordingly, in one implementation an intubation-tube placement device 100 secured to an intubation tube 116 comes pre-packaged, as a unit, in a medical-grade sterile package. This is particularly attractive over the related art in that that when the intubation- tube placement device 100 secured to an intubation tube 116 is removed from its packaging it is substantially immediately ready to be used. That is, the intubation-tube placement device 100 secured to an intubation tube 116, prepackaged as a unit in medical-grade sterile packaging, has the advantage of saving time from having to load it.

The foregoing has described various devices. Following is a description of one method implementation which illustrates how several of the foregoing-described various devices may be used.

With reference now to Figure 12, shown is a high-level logic flowchart depicting a process which illustrates how various of the foregoing-described devices may be used. Those skilled in the art will recognize that the uses depicted and/or described are merely illustrative, and are not exhaustive. Referring now to Figures 12A, 12B, and Figure 1A, method step 1200 depicts the start of the process. Method step 1202 illustrates positioning a patient's head and opening the patient's mouth to allow a straight line of access from the mouth to the vocal cords as in the related art (typically with the aid of a lighted laryngoscope). Method step 1204 shows the health-care provider positioning the intubation-tube placement device 100, relative to the intubation tube 116, in a location appropriate to the patient undergoing intubation and/or in accordance with the health-care provider's preference; in one implementation, this is achieved via the health-care provider grasping the intubation tube 116 and/or the rubber stopper 118 with one hand and manipulating the intubation-tube placement device with the other hand until the anti-perforation device 102 extends from the intubation tube 116 at a distance which the health-care provider deems appropriate (e.g., extending 5 cm from the intubation tube for neonates or extending 20 cm from the intubation tube for average-sized adults).

Method step 1206 depicts the health-care provider grasping the intubation tube 116 and/or the rubber stopper 118, and thereafter inserting the intubation-tube placement device 100, secured to the intubation tube 116, into the patient's oral cavity. Method step 1208 illustrates the health-care provider manipulating the intubation-tube placement device 100, secured to the intubation tube 116, such that the anti-perforation device 102 may be used to manipulate the epiglottis out of the line of sight so that the patient's vocal cords may be visualized where standard laryngoscope manipulation fails to reveal the cords. Additionally, when the vocal cords are not otherwise able to be visualized through laryngoscope or the device described herein' s manipulation, the exploratory portion of the device can be gently advanced as anterior as possible to the posterior aspect of the visualized epiglottis or where the health-care provider best believes the epiglottis to be to facilitate insertion within the trachea. The device's design allows for endotracheal placement interpretation by allowing the health-care provider to appreciate either the cartilaginous rings lining the trachea through tactile stimulus or until hang-up of the device (usually at the bifurcation of the trachea) is experienced strongly suggesting endotracheal intubation; in one implementation, the light source internal to the anti-perforation device 102 aids the health-care provider in this process. One advantage to this one implementation of the light source is the ability of the health-care provider to otherwise dispense with the necessary reliance upon an expensive lighted laryngoscope and the accompanying supportive costs to maintain laryngoscopes (sterilization, changing light bulbs, incompatible blades, bulbs, etc). This implementation allows for as many intubations as there are devices for without reliance upon sterilizing procedures or other costly supportive maintenance. In addition to the foregoing, the inventor has found that one particularly advantageous use of the structures described herein is that the intubation- tube placement device 100 having anti -perforation device 102 and/or tactile-accentuator rings 114 allows for blind placement without any light source, or use of even a laryngoscope blade, by simply using the health-care provider's fingers to first identify the position of the epiglottis and then to slide the exploratory portion of the device as anterior as possible again to the posterior aspect of the epiglottis to facilitate endotracheal intubation until tactile confirmation suggests endotracheal intubation. In one use, the endotracheal intubation is confirmed through bagging and other standard confirmatory techniques. The inventor points out that the foregoing-described blind intubation may be very attractive where a health-care provider may want to otherwise intubate a patient under low lighting or unfavorable conditions such as out in the pre-hospital setting or in a combat area.

Method step 1210 depicts the optional step of suctioning materials from the vicinity of the patient's vocal cords; in one implementation, the foregoing is achieved via the trailing portion 104 of the anti-perforation device 102 coupled to the intubation-tube placement device 100 such that the channel 300 of the anti-perforation device 102 substantially aligns with the hollow tube formed by the intubation-tube placement device 100, thereby forming a suctioning tube (e.g., see Figures 3 A and 3B).

Method step 1212 shows the step of the health-care provider positioning the exploratory portion 106 of the anti-perforation device 102 in a position such that the anti- perforation device 102 can traverse the patient's vocal cords; in one implementation, the health-care provider is aided in this task of positioning in that the intubation-tube placement device 100 secured to the intubation tube 116 serves as a "handle" for the intubation-tube placement device 100, where the "handle" tends to "amplify" the movements of the health-care provider's fingers to allow for very accurate positioning of the intubation-tube placement device 100 (and hence the anti-perforation device 102) within the patient's oral cavity.

Method step 1214 depicts the step of the health-care provider forcing the intubation-tube placement device 100 (and hence the anti -perforation device 102) through the patient's vocal cords; in one implementation, the foregoing is achieved via the healthcare provider grasping the intubation-tube placement device 100 near the rubber stopper 118, and applying pressure along the axis of the intubation-tube placement device 100 such that the intubation-tube placement device 100 slides axially within the hole of the rubber stopper 118 such that the exploratory surface 106 of the anti-perforation device 102 pushes aside the patient's vocal cords.

Method step 1216 illustrates the step of the health-care provider continuing to apply axial pressure along the intubation-tube placement device 100 such that the intubation-tube placement device 100 (and hence the anti-perforation device 102) moves further into the confines of the patient's body, making sure that the intubation-tube placement device 100 enters the patient's trachea rather than the patient's esophagus; in one implementation, the health-care provider is aided in the foregoing-described endeavor by the tactile-accentuator flaps 114, in that various of the tactile-accentuator flaps 114 impact upon the cartilaginous rings lining the trachea, and mechanically transmit such impact, back through the intubation-tube placement device 100, such that the health-care provider performing the intubation can be substantially assured that he has placed the intubation- tube placement device 100 in the trachea rather than in the esophagus.

Method step 1218 shows the step of the health-care provider axially sliding the intubation tube 116 along the intubation-tube placement device 100 such that the intubation tube 116 follows the intubation-tube placement device 100 through the patient's vocal cords; in one implementation, this is achieved via the health-care provider grasping the intubation-tube placement device 100 and sliding the rubber stopper 118 axially along the intubation-tube placement device 100 such that the intubation tube 116 clears the patient's vocal cords.

Method step 1220 depicts the step of the health-care provider inflating an inflatable cuff of the intubation tube 116, as in the related art. Thereafter, method step 1222 illustrates the step of the health-care provider removing the intubation-tube placement device 100 and the rubber stopper 118 from the intubation tube 116; in one implementation, this is achieved via the health-care provider simultaneously grasping the intubation-tube placement device 100 and the rubber stopper 118, and pulling the intubation-tube placement device 100 and the rubber stopper 118 from the intubation tube 116. Method step 1224 shows the end of the process.

As noted in the above-referenced provisional patent application, filed 05 Mar. 2001, and hereby incorporated by reference, in its entirety, in the present detailed description, the methods and devices described herein differ from the related-art use of the Eschmann stylet in several ways. For example, the related-art Eschmann stylet does not have an anti-perforation device, such as has been described herein, and, in fact, the present inventor has observed the Eschmann stylet perforating body tissues (e.g., a tumor) during use. The anti-perforation device described herein decreases the likelihood that such perforation will occur and hence provides an advantage over the related-art Eschmann stylet. In addition, in use, a health-care provider first passes the related-art Eschmann stylet through a patient's vocal cords, and thereafter the health-care provider introduces the endotracheal tube over the Eschmann stylet, in through the patient's vocal cords into the patient's trachea. The inventor points out that, according to the Eschmann stylet's manufacturer's recommendation it is intended as a rescue device and only for use only after failed conventional laryngoscopy, whereas the herein described one unit assembly design (i.e., the intubation-tube placement device 100 secured to the intubation tube 116) permits attempted intubation during all scenarios ~ a characteristic feature not known to any other device. In contrast, the intubation-tube placement device secured to an intubation tube, such as has been described herein, is used differently in that it allows the intubation-tube placement device secured to the intubation tube to be placed as a unit, thereby increasing the speed and ease of intubation over the related-art use of the Eschmann stylet. The inventor has found empirically that the one unit assembly character of the intubation-tube placement device 100 secured to the intubation tube 116, described herein, provides a much larger surface area to be held by the health-care provider thereby greatly improving their ability to control the device and improve the success rate of intubations. The inventor has found empirically that the Eschmann stylet's surface area held by the health-care provider is considerably smaller and therefore more difficult to grasp and more importantly control with control being a critical feature during any attempted life saving procedure. Additionally, the inventor has found empirically that the Eschmann stylet's resin-coated exterior is very susceptible to cracking and flaking which can lead to foreign objects being aspirated into the bronchial airway system and to be a site for foreign debris to be retained. The inventor also points out that the Eschmann stylet is not intended to be a disposable item (as are most implementations described herein), and that the Eschmann stylet is costly to produce whereas the devices described herein is, in most implementations, entirely disposable and therefore not reliant upon a sterilizing process before use. In addition, the methods and devices described herein differ from the related-art lighted wand technique in several ways. For example, the related-art lighted wand technique uses an intense light to trans-illuminate a patient's laryngeal structures internally which can be seen from the exterior of a patient's body to place an endotracheal tube. In contrast, the methods and devices described herein allow for placement of the endotracheal tube either blindly or by direct visual inspection of the interior of the patient's mouth and vocal cords, and light source described herein facilitates such placement by direct visual inspection.

In addition, the methods and devices described herein differ from the related-art devices and techniques in that none of the related-art devices and techniques used tactile-accentuator flaps to detect the cartilaginous rings of the patient's trachea, nor do the related-art devices and techniques provide for suction via the use of an intubation- tube placement device such as has been described herein.

From the foregoing it will be appreciated that, although specific embodiments of the invention have been described herein for purposes of illustration, various modifications may be made without deviating from the spirit and scope of the invention. Accordingly, the invention is not limited except as by the appended claims.

The foregoing described embodiments depict different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively "associated" such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as "associated with" each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being "operably connected", or "operably coupled", to each other to achieve the desired functionality.

While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from this invention and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of this invention.

For example, although the tactile-accentuator flaps have been described herein in the context of a specifically-crafted intubation-tube placement device, it is to be understood that such tactile-accentuator flaps would also have utility when used with other devices utilized to place intubation tubes (e.g., the Eschmann stylet, fiber optic scopes, bronchoscopes, etc.). As another example, although the specifically-crafted intubation- tube placement device secured to an intubation tube has been described herein, it is to be understood that the foregoing-described structure would also have utility when used with other devices utilized to place intubation tubes (e.g. the Eschmann stylet, the lightwand, fiber optic intubating scopes, etc.).

As another example, although the intubation-tube placement device has been shown and described herein as having a relatively constant diameter, it is to be understood that, insofar as the intubation-tube placement device will likely be compression molded, the intubation tube placement device could have several equally-functional diameters and/or shapes. For example, in other contemplated implementations, the intubation-tube placement device is formed to be tapered at an exploratory end (e.g., the end to be inserted into a patient, and to which an anti-perforation device could be affixed), and flared wider where the intubation-tube placement device accommodates an intubation tube (e.g., the portion of the intubation-tube placement device upon which the intubation tube would be secured could be of significantly wider cross section than the exploratory end, thereby rendering the intubation-tube placement device secured to the intubation tube that much more stable).

As another example, in another contemplated implementation, it is to be understood that since the drawings set forth herein are not limited in scale, encompassed in such drawings and description is a modified intubation tube, as described above, which has a tip on its exploratory end that is sufficiently open so that a suction catheter may be introduced down in and through the modified intubation tube in order to access the deep trachea. The foregoing-referenced tip allows the health care provider to suction out secretions which accumulate and can't be cleared by a patient, who, for example, might be intubated and on a respirator. The inventor points out that this implementation of the modified intubation tube yields attractive benefits.

Furthermore, it is to be understood that the invention is solely defined by the appended claims. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted to mean "at least one" or "one or more" ); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically means at least two recitations, or two or more recitations).
