Endotracheal tubes (ETT) are known in the art—one non-limiting example (copied from US published patent application 20120097168 incorporated herein by reference) is illustrated in
The following issued patents and patent publications provide potentially relevant background material, and are all incorporated by reference in their entirety: U.S. Pat. No. 7,866,477 entitled “Oral care Q2 kits”; U.S. Pat. No. 4,984,984 entitled “Dental tool and nozzle therefor”; and WO 2005/070324 entitled “Droplet Jet System For Cleaning”, WO 1995/006492 entitled “Cuffed Oro-Pharyngeal Airway and U.S. Pat. No. 2,099,127 entitled ““Pharyngeal Bulb Gasway.”
It is now disclosed a reversibly/side mountable system for oral care of patients ventilated with an endotracheal tube (ETT), the system comprising: a deformable fluid blocking element reversibly mountable and side-mountable around the ETT, the fluid blocking element having: (i) a midsection channel sized to fit snugly and reversibly around the ETT when the fluid blocking element is mounted thereto; and (ii) an outer surface configured, when the fluid blocking element is mounted, to fit snugly and reversibly into the back of the mouth of an adult human patient so as to span both lateral left-to-right tonsils and tongue-soft palate dimensions thereof, wherein the fluid blocking element is configured so that when mounted to the ETT, (A) the fluid blocking element is reversibly inflatable to simultaneously press against the soft palate and the tongue and/or (B) the fluid blocking element is collapsible and outwardly biased so that when placed in the back of the human mouth, the fluid blocking element expands so as to simultaneously press against the soft palate and the tongue.

The invention is herein described, by way of example only, with reference to the accompanying drawings. With specific reference now to the drawings in detail, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of the preferred embodiments of the exemplary system only and are presented in the cause of providing what is believed to be a useful and readily understood description of the principles and conceptual aspects of the invention. In this regard, no attempt is made to show structural details of the invention in more detail than is necessary for a fundamental understanding of the invention, the description taken with the drawings making apparent to those skilled in the art how several forms of the invention may be embodied in practice and how to make and use the embodiments.
For brevity, some explicit combinations of various features are not explicitly illustrated in the figures and/or described. It is now disclosed that any combination of the method or device features disclosed herein can be combined in any manner —including any combination of features—any combination of features can be included in any embodiment and/or omitted from any embodiments.
In relation to the figures the following numbers indicate:
In the non-limiting example of
In order to clean the subject's gums and/or teeth, is possible to deliver a pressurized fluid (e.g. a spray or mist or jet of fluid) into the subject's mouth at a time when the fluid blocking element 200 is deployed within the back of the subject's mouth so as to substantially fill the entirety of the annular region outside of ETT 120 within the back of the subject's mouth. The presence of fluid-blocking element substantially blocks fluids associated with the gums/teeth cleaning process (i.e. ‘cleaning fluids’) from penetrating deeper into the patient's oral cavity. Because the cleaning fluids may include oral-cavity microbes (e.g. derived from plaque or oral biofilm which may mix with the cleaning fluids after introduction into the oral cavity), blocking of these microbes-containing fluids by fluid blocking element 200 may reduce or eliminate collateral contamination of the trachea associated with the cleaning of the teeth or gums.
Some embodiments relate to kits including both the fluid-blocking element 200 and a spray-head device for delivering a pressurized stream of fluid into the subject's mouth. Other embodiments relate to systems including fluid-blocking element 200 which may or may not include the spray-head device. A more detailed discussion about example spray-head devices with reference to
In order to further protect the trachea from microbes mixed into the cleaning fluid, and in order to further reduce the rate at which contaminating cleaning fluid leaks into locations below fluid-blocking element 200, it is possible to suction the contaminated or ‘used’ cleaning fluids from a location above the fluid-blocking element 200. In the non-limiting example of
In some embodiments, one or more tubes of tube assembly 220 is attached to the fluid-blocking element 200 so that a distal end thereof (e.g. 222 or 224 as illustrated in
As noted above, fluid-blocking element 200 may snugly fit within the subject's mouth so as to substantially fill the entire annular region outside of the ETT 120 and within the back of the subject's mouth. Although fluid-blocking element 200 is not required to be shaped as a rectangular prism, roughly speaking, fluid-blocking element 200 may include six ‘outer’ surfaces: (i) a soft-palate facing surface 630 facing and in contact with (or nearly in contact with) soft palate 740; (ii) a tongue-facing surface 620 facing and in contact with (or nearly in contact with) tongue 710; (iv) left-tonsil and right-tonsil facing surfaces (not numbered in the figures); (v) proximate surface 640 and (vi) distal surface 650.
The term ‘outer surface’ of the fluid blocking element refers to the union of all of the six aforementioned surfaces. This is in contrast to the ‘inner surface’ discussed below which is the surface of the midsection channel 205 faces the ETT. In order for the ‘outer surface’ to fit snugly into the back of the mouth, the following two activities must occur simultaneously (i) the soft-palate facing surface 630 must press onto the soft palate and (ii) the tongue-facing surface 620 must press onto the tongue.
In some embodiments, the fluid blocking element permanently has an annular shape and is top-mounted onto the ETT (e.g. by sliding onto the ETT at the top/proximal end). In preferably embodiments, the fluid blocking element has a ‘clip on’ or is otherwise side-mountable to the ETT. This allows for mounting the fluid blocking element to the ETT and removing the fluid blocking therefrom to clean the patient's teeth with no need to even briefly interrupt ventilation of the patient.
Fluid-blocking element 200 may also include an inner surface—i.e. a surface of the midsection channel 205 through which ETT 120 passes. This inner surface is referred to as ETT-facing surface 210 and is typically shaped like a side of a cylinder or a portion thereof. When ETT 120 passes through the midsection channel 205, there is a snug fit between an outer surface of ETT 120 and ETT-facing surface 210.
In the example of
Also illustrated in
Alternatively, as illustrated in
In some embodiments, employing a fluid blocking element 200 that is not annular in shape allows for one to ‘clip on’ blocking element onto ETT 120 and ‘clip off’ blocking element from ETT 120 without an need to slide into place the fluid blocking element from an end (e.g. proximal end) of ETT 120. The “open arc” fluid channels 205 illustrated in
One advantage of the ‘open arc’ configuration is that the fluid blocking element can be side-mountable to the ETT. In another example, the fluid blocking element is sometimes annular in shape and sometimes has an open arc and is also side-mountable.
Fluid-blocking element 200 may be compressible and/or expandable to snugly fit within the human oral cavity, particularly at the back of the mouth behind the back teeth 110 and near the soft palate 740, spanning the width between the left 115 and right 114 tonsils. For that purpose, blocking element 200 may, in different embodiments, be primarily constructed from foam, and/or sponge, and/or diaphragm, and/or inflatable balloon.
In some embodiments, ETT-facing surface 210 of midsection channel 205 may be made of a relatively stiff non-compressible material. In such case, where the stiff surface 210 is an arc of more than 180 degrees, the stiff surface 210 can clip-on with stronger attachment on the ETT 120.
Because ETT 120 passes through blocking element 200 (i.e. through mid-section channel 205 thereof), a diameter of channel 205 is sized to enable an outer surface ETT 120 to go through blocking element 200. Typical outer diameters of ETT (e.g. ETT tubes) are in the range of 6 mm-13 mm.
As noted above, fluid blocking element 200 is not required to be shaped as a rectangular prism.
In embodiments, the liquid delivery tube 531 and gas delivery tube 533 are detachable/re-connectable from/to the elongated body 510. Thereby, the elongated body 510 may be disposable while the delivery tubes can be re-used with other main body 510 devices.
In operation, the spray device is to be connected with a pressurized gas source 543, and to a liquid reservoir 541. The liquid reservoir may or may not be pressurized relative to atmospheric pressure. In embodiments, the gas source is pressure is between 2-8 atm, in order to create spray 590 suitable for cleaning of dental biofilm and/or plaque.
In embodiments, the lumens 521 and 523 are simultaneously extruded.
In operation of the spray device 500, the gas streams (flows) intercept the liquid flow at an angle, preferably approximately perpendicularly. The velocity of the gas flows is sufficient to break up the liquid stream into a spray of droplets of desired size and velocity, optionally accelerating them through an acceleration duct and out of the orifice 520 at a desired high velocity effective for removal of biofilm and/or plaque from teeth and/or gums.
For convenience, in the context of the description herein, various terms are presented here. To the extent that definitions are provided, explicitly or implicitly, here or elsewhere in this application, such definitions are understood to be consistent with the usage of the defined terms by those of skill in the pertinent art(s). Furthermore, such definitions are to be construed in the broadest possible sense consistent with such usage.
Some embodiments relate to a ‘width’ of an objection—for example, a ‘width’ of an elongate flexible main body 210 or a width of an orifice(s) or a width of a lumen. A ‘width’ is defined as the square root of the cross section.
Additional Discussion
Embodiments of the present invention relate to a system for oral care of patients ventilated with an ETT, the system comprising a deformable fluid blocking element that is reversibly mountable around the ETT—e.g. slidable along the ETT when mounted thereon. The ‘reversibly mountable’ feature of the fluid blocking element means it can be mounted to and detached from the ETT, in contrast to any permanent attachment such as one based on gluing the fluid blocking element to the ETT.
The fluid blocking element has (i) a midsection channel 205 sized to fit snugly and reversibly around the ETT 120 when the fluid blocking element is mounted thereto; and (ii) an outer surface configured, when the fluid blocking element is mounted, to fit snugly and reversibly into the back of the mouth of an adult human patient so as to span both lateral left-to-right tonsils and tongue-soft palate dimensions thereof.
For the present disclosure, when the fluid blocking element fits “snugly” into the back of the mouth outer pressure is applied, by the fluid blocking element, simultaneously on both the tongue (e.g. the back of the tongue) and the soft palate. There is no requirement that outward pressure is applied upon any surface other than the on the tongue and the soft palate, although such pressure may, in fact, be applied.
In some embodiments, the fluid blocking element 200 is reversibly inflatable (e.g. including a balloon) to simultaneously press against the soft pallet and the tongue and/or the fluid blocking element 200 is collapsible and outwardly biased so that when placed in the back of the human mouth, the fluid blocking element expands so as to simultaneously press against the soft pallet and the tongue.
In exemplary embodiments, the fluid blocking element may be provided as a balloon and/or foam and/or sponge and/or diaphragm.
In some embodiments, the fluid blocking element permanently has an annular shape and is top-mounted onto the ETT (e.g. by sliding onto the ETT at the top/proximal end). Alternatively, the fluid blocking element has a ‘clip on’ or is otherwise side-mountable to the ETT. This allows for mounting the fluid blocking element to the ETT and removing the fluid blocking therefrom to clean the patient's teeth with no need to even briefly interrupt ventilation of the patient.
Some embodiments relate to an oral cleaning kit comprising: (i) the aforementioned reversibly mountable deformable fluid blocking element and (ii) a spray device for spraying a fluid into the oral cavity to clean the teeth. When fluid is sprayed into the intubated oral cavity, the presence of the fluid blocking element blocks fluids from penetrating into the airway below the blocking element.
In patients intubated with an endo tracheal tube (ETT), the ETT inhibits the swallowing ability. Hence cleaning the oral cavity with streams of liquid containing fluids is problematic, since oral biofilm and/or plaque contaminated fluids may descend into the trachea and the lungs. By combining the use of a fluids blocking element 200, the oral care kit facilitates safe use of fluids spray device 500 for cleaning of the teeth and/or gums of patients intubated with an endo tracheal tube (ETT).
Preferably, suctioning means are connected to the fluids blocking element 200, such that the contaminated cleaning fluids are not only blocked from descending into the trachea but are also suctioned out of the patient oral cavity.
In use of preferred embodiments, the fluids blocking element 200 is first fitted over the ETT at the back of the oral cavity of the intubated patient. Suctioning is operated to suction fluids proximally to the blocking element 200. The fluids spray device 500 is then operated to cleaning the patient oral cavity while suctioning.
