FIELD OF THE INVENTION
The subject application relates to medical devices and, more particularly to endotracheal tubes, and a device for positioning and repositioning endotracheal tubes when used with a patient.
BACKGROUND OF THE INVENTION
Medical endotracheal tubes and holders have been successfully utilized on intubated patients since their commercial introduction. Once such product is the Model No. 270 Endotracheal Tube Holder, commercially available from Dale Medical Products, Inc. of Franklin, Mass. 02038. U.S. Pat. No. 8,096,300 titled “Endotracheal Tube Holder” issued Jan. 17, 2012, hereinafter referred to as the '300 patent or '300 holder, further describes such an endotracheal tube holder.
The '300 holder is intended to maintain the endotracheal tube securely within a patient's oral cavity and to prevent inward or outward movement of the endotracheal tube relative to patient's oral cavity. However, newer medical protocol requires positioning and repositioning of the endotracheal tube, typically left, center, or right, within a patient's oral cavity to prevent mouth, lip, and/or tongue pressure sores caused by leaving the endotracheal tube in one position longer than 8 hours. As such, side to side repositioning of the endotracheal tube within the patient's oral cavity is routinely and repeatedly required. Ideally, the endotracheal tube side to side repositioning procedure should be performed at least three times per day while still trying to maintain tube security and fixation. However, the '300 holder requires removal of the neckband from around the patient's neck and separation of the neckband from the facial anchoring device to accomplish side to side movement of the tube within the patient's oral cavity or to perform oral hygiene.
Accordingly, a need exists for a mechanism that permits easy side to side repositioning of the endotracheal tube within the patient's oral cavity.
In an additional need exists for a mechanism that permits rapid side to side repositioning of the endotracheal tube within the patient's oral cavity.
A further need exists for a mechanism that permits side to side movement of the endotracheal tube within the patient's oral cavity, without having to disengage the neckband.
SUMMARY OF THE INVENTION
An endotracheal tube positioning device for providing fixed positioning and slidable repositioning of a patient's endotracheal tube within a patient's oral cavity comprises a neckband, slide track member, a bracket for securement of the tube, and a flexible overlay strip. The slide track member, bracket, and overlay strip are affixed to the neckband. The device permits slidable side-to-side adjustment of the secured endotracheal tube within the patient's oral cavity without having to remove or detach the neckband from around the patient's neck. The bracket can be secured to the endotracheal tube by with an adhesive backed tape or a tube securement strap having engagement elements mating with an adhesive backed patch adhered to the endotracheal tube.

FIG. 1 illustrates conceptually an endotracheal tube assembly 10 according to embodiments fore use with an endotracheal tube holder system 11. Assembly 10 comprises a neckband 18, which can be extended over the patient's cheeks and secured behind a patient's head or neck region using hook securement tabs 19 and 20. A face anchoring device 21 anchors neckband 18 in place on the patient's upper lip 22. Neckband 18 extends about the patient's head and neck. A portion of neckband 18, neckband platform 15, defines a surface to which system 11 is attachable. System 11 comprises a slide track member 12, bracket 16 and retention strip 17, as illustrated. Slide track member 12, bracket 16, and overlay strip 17 form the basic components of system 11 and are discussed in greater detail in further drawings.
Slide track member 12 may be implemented with a substantially flat rectangular or ribbon-shaped piece of material having ends 13 and 14 thereof secured to neckband platform 15. Ends 13 and 14 may be secured to neckband platform 15 by sew, adhesive, or other process, such as sonic welding, depending on the nature and composition of the materials comprising member 12. Slideably mounted onto slide track member 12 is bracket 16. Overlaying both slide track member 12 and bracket 16 is flexible overlay retention strip 17.
FIG. 2 illustrates conceptually bracket 16 in greater detail. In embodiments, bracket 16 may have a generally L-shaped profile with a first leg extending along an axis 90 and securable to the endotracheal tube, the bracket further having a second leg retained relative to the platform 15 forward facing surface but slidably movable in directions normal to the axis. Bracket 16 has a loop defined by apertures 29 and 30 formed on the shorter leg thereof, and into which slide track member 12 can be threaded, and an arcuate bracket extension 27 formed on the longer leg thereof to accommodate the endotracheal tube. In embodiments, bracket 16 may have a molded-in rearward curve 33 which prevents any upper lip 22 contact to prevent any pressure sores from being caused by bracket 16. Bracket 16 can be injection molded from a semi flexible plastic, such as DEHP free Colorite PVC resin of about 80 Shore A durometer.
FIG. 3 is an exploded perspective view of the system 11 relative to neckband platform 15 and face anchoring device 21 prior to assembly on the neckband platform 15. Specifically, bracket 16 is slidably engaged with slide track member 12 through apertures 29 and 30. Slide track member 12 may be fabricated from a firm loop material having a frontal loop area 34. Bracket 16 is free to slide along member 12 in either direction 35 and 36. Slide track member 12 is sewn or sonic welded onto neckband platform 15 proximate ends 13 and 14. Flexible overlay retention strip 17 made from polypropylene low profile hook has a rearward hook surface area 37 which is engageable and disengageable with frontal loop surface area 34 on slide track member 12. Retention strip 17 is stitched on only one side 38 to side 14 on slide track member 12. Opposite side 39 of retention strip 17 is not sewn in place and forms a lift edge on strip 17 permitting engagement and disengagement with slide track member 12. Strip 17 may include a front facing printable surface 40 having legend 41 containing instructions or information useful to a clinician, such as “LIFT”, on strip 17. Printing may include a repeat pattern of information.
FIGS. 4 and 5 illustrate the functional components of system 11 and how engagement and disengagement of overlay strip 17 with the slide track member 12 permits fixed positioning, slidable repositioning along the slide track member 12 to another fixed position of the bracket 16 on the slide track member 12. FIG. 4 is a top view of assembled system 11 attached to the neckband platform 15. FIG. 5 illustrates from a frontal view all the assembled elements from FIG. 3. As can be seen from both FIGS. 4 and 5, overlay strip 17 can be adhered and engaged with both slide track member 12 and neckband 18. Such adherence and engagement prevents bracket 16 from pivoting downward and the bracket 16 securely affixed to neckband 18. In use, once the rearward hook surface 37 of strip 17 is engaged with the frontal loop area 34 on slide track member 12, bracket 16 remains in a fixed retained position and cannot be easily or slidably moved. Strip 17 can be manually disengaged from slide track member 12, by lifting up and disengaging strip 17 from slide track member 12. The clinician can then permit side to side repositioning of bracket 16. Re-engagement of retention strip 17 with slide track member 12 permits the bracket 16 to be fixed in the new position.
FIG. 6 is a side view of the system 11 attached to a patient's face using dual tapes 23 and 24 to fasten endotracheal tube 28 onto bracket extension 27. Non-adherent mylar polyester tips 25 and 26 permit a convenient graspable edge during wrapped adherence of the tapes as well as a convenient graspable edge to remove both tapes 23 and 24, if desired. Removable tapes 23 and 24 which are die cut on a back release liner 42 can be used to secure an endotracheal tube 28 in place by taping around bracket extension 27. Tape 24 can be wrapped around bracket extension 27 while the second tape 23 can be wrapped around frontal bracket tabs 31 and 32 to secure tube 28 in place and prevent inward or outward movement of the tube 28 within a patient's airway and/or oral cavity 43.
FIG. 7 is an exploded perspective view of an embodiment of system 11 wherein slide track member 44 comprises a low profile molded hook component having a frontal hook face surface 45 and overly strip 46 comprises a loop material having a rearward engagement surface 47. This embodiment of system 11 operates in similar manner as illustrated in FIGS. 3-5 such that bracket 16 is proximate to oral cavity 43. The version illustrated in FIG. 7 may be preferred by some clinicians since the slide track member 44 utilizes a non-absorbent molded plastic hook on the bracket platform 15 which may resist oral secretions over extended use.
FIG. 8 depicts how system 11 can be modified to utilize a non-tape securement device to secure endotracheal tube 28 in place in a patient's airway oral cavity 43 as illustrated in FIG. 6. Bracket 48 may also comprise plastic molded from semi-flexible DEHP free PVC but terminates in an end portion 49 of about 0.060 inches in thickness to permit sewable or sonic weld attachment of flexible strap 50 on top 51 of strap 50. Strap 50 can be made from a variety of laminated hook and loop materials sometimes called laminated hook and loop. Strap 50 can have a top hook surface 52 engageable with underside loop material surface 53 in a wrapped manner.
FIG. 9 illustrates in a cross sectional view how strap 50 will form an interlocking engagement with adhesive backed low profile hook patch 54 which can be adhesively applied to endotracheal tube 28. Patch 54 has a molded-in hook top surface 55 which engages with underside loop surface 53 on strap 50. This engagement to secure mechanism 11 in place on tube 28 is further illustrated in FIG. 9. Strap 50 can firmly attach mechanism 11 onto tube 28 while preserving the functional side to side adjustment of mechanism 11 within the oral cavity of a patient.
FIG. 10 depicts a commercial embodiment of the mechanism bracket assembly 56 having bracket portion 57 that incorporates a slide track member 58 utilizing a double sided knit loop. Both knit front side 59 and rear side 60 are laminated together to form a strong yet semi flexible slide track member 58 having both a soft loop front and rear side surface area permitting a smooth side to side slide action of slide track member 58 with a bracket portion 57. Slide track member 58 has die cut rounded ends 61 and 62 permitting ease of insertion during manufacturing assembly of slide track member 58 into and through bracket slot 63. Slide track member 58 is member tack stitched or sonic welded attached on both ends 64 and 65 onto cushioned neckband platform 66. Knit loop front side 59 on slide track member 58 will fully engage with the overlay strip 17 having rearward hook surface area 37 as previously shown, described, and depicted from FIGS. 4 and 5. Bracket portion 57 also incorporates bracket extension 67 which is about 1.750 inches long and terminates in shortened semi circular end tabs 68 and 69 which permit increased tube securement area to be tape in place. The bracket extension 67 is also referred to as a bracket extension channel or just a channel.
FIG. 11 illustrates a singular specially fabricated endotracheal tube securement tape 70. Tape 70 may be an adhesive backed fabric tape made from fabric adhesive backed material, approximately 1 inch wide by 6 inches long and die cut on a factory release liner 71. Tape 70 terminates at its very end with a non-adherent tip 72 having a 3 mil mylar plastic underside backing 73. Tape 70 can be supplied in kit form along with adhesive backed anchoring device 21 as shown and described in FIGS. 1 and 3. Tape 70 uses an aggressive high tack synthetic rubber adhesive 74 which forms a strong adhesive bond with the PVC plastic material used both in the bracket extension channel 67 shown in FIG. 10 and most PVC endotracheal tubes 28 as shown and described from FIG. 1. Alternately, a mini roll of medical cloth tape can be substituted, supplied and packaged as an alternate tape securement means to tape 70.
FIG. 12 illustrates the complete final commercial mechanism 75 incorporating the bracket assembly 56 from FIG. 10 and the adhesive backed tape 70 from FIG. 11. As can be seen from FIG. 12, there is illustrated a neckband platform portion 76 which is proximate to a patient's oral cavity wherein the mechanism assembly 77 is attached to the neckband portion 76. The mechanism assembly 77 incorporates a slide track member 78 having a frontal engagement surface 79. A bracket portion 80 is slideably moveable on the slide track member 78. A flexible overlay retention strip 81 has a rearward engagement surface 82 which matingly engages and disengages with the frontal surface 79 on slide track member 78. The rearward surface 82 on retention strip 81 overlays both the slide track member frontal surface 79 and the bracket portion 80.
As can be seen, the overlay retention strip 81 rearward surface 82 permits fixed positioning and slideable movement and repositioning of the bracket portion 80 when engaged or disengaged with the slide track member 78. Such slidable movement is in either direction, as illustrated by the arrow 35 and 36 of FIG. 3, normal to the axis 90 of the bracket extension 67 and endotracheal tube, as illustrated in FIG. 12. The mechanism assembly 77 permits fixed positioning when engaged and slideable repositioning when disengaged to another fixed position of the bracket portion 80. All of this takes place without the clinician having to remove the neckband platform portion 76 from the patient's face.
From FIG. 12, endotracheal tube 83 is secured in place within a patient's oral cavity utilizing bracket extension channel 67 and adhesive backed supplied tape 70. The instructions for the spiral motion application of the tape 70 to the bracket extension channel 67 and endotracheal tube 83 is clearly listed as part of FIG. 12.
Non-adherent tape tip 72 permits an easy finger grip tip to aid in application of the tape while 3 mil polyester plastic underside backing 73 on tape 70 offers a convenient lift off edge to permit removal of the tape from the bracket extension channel and tube when removal or replacement of the entire commercial mechanism 75 is required. Typically, this takes place once every three days or so.
