Description

TECHNICAL FIELD

The present disclosure generally relates to devices, and related methods of treatment using the same, for securing an endotracheal tube (commonly abbreviated as “ETT”) or other medical line to a patient, and more particularly to infants, babies in a neonatal unit, small children, etc.). The disclosure also relates to techniques and devices which prevent unplanned extubations. In an exemplary embodiment, as taught in the present disclosure, a device may be used to secure an endotracheal tube to a small child or newborn infant such that the device may be configured to adjust the grip of the endotracheal tube to achieve optimal securement and stabilization of the endotracheal tube.

BACKGROUND

Endotracheal tubes are commonly used on medical patients, for example, to mechanically ventilated patients. Placement of an endotracheal tube into the throat of a patient is referred to as intubation. Failing to secure the endotracheal tube properly, however, can result in the migration of the tube within the throat of the patient. This may be referred to as an unplanned or unintended extubation. Such motion is undesirable since outward motion of the tube can result in the tube moving entirely out of the airway of the patient, eliminating its effectiveness, and potentially ventilating the patient's gastro-intestinal tract instead of their lungs. Inward motion of the tube is undesirable because it may eventually result in the tube moving down one of the patient's bronchi, preventing air from being ventilated to the other lung. This may quickly lead to the collapse of the unventilated lung. Even slight back and forth motion of the tube within the throat can result in tracheomalacia and ultimately in the weakening or collapse of the trachea, which may require permanent stenting to maintain an open airway. Migration may further result in a form of nosocomial pneumonia. This undesirable removal or movement of the endotracheal tube, alluded to above, may result in an unintended or accidental extubation. Unintended or accidental extubation is a serious medical emergency, which can have a dire outcome such as morbidity, permanent medical damage, or death.

With some patients, such as young children or neonates (e.g., newborn babies), the securement and stabilization of an endotracheal tube is critical, especially in the immediate days after birth to ensure that proper breathing and oxygen delivery is met. With such patients, current devices for gripping or securing the endotracheal tube to the baby's face or mouth may be sub-optimal due to a poorly designed or manufactured gripping device and/or owing to the baby's newborn physiology (i.e., newborn baby's skin composition and sensitivity to certain adhesives). In present endotracheal tube gripping devices commercially available, tabs and/or “lollipops” may become loose and lift from the young patient's face (e.g., the newborn baby's face). With some devices that utilize hook and loop fasteners (i.e., Velcro), the fasteners securing the endotracheal tube, if too loose, may cause the endotracheal tub to slip, and, if too tight, may not permit the suction catheter to pass. In such presently available tube gripping devices, if the endotracheal tube moves even slightly, it may cause an unplanned extubation, which may lead to the newborn baby losing critical oxygen supply or the delivery of other medical treatment through the tube. Certain existing devices may also block access to the oral cavity of the patient, resulting in difficulty in oral care which may lead to infection. Said infection may become particularly serious if it travels down the tube and into the lungs of the patient.

In order to avoid these undesirable consequences, it is common to secure the endotracheal tube in position upon the patient by means of adhesive tape. For instance, a medical practitioner may, after positioning the tube within the throat of the patient, wrap adhesive tape around the tube and tape it to the patient. Various devices are often used as adaptors for endotracheal tubes, and sometimes these devices are taped to the patient instead of directly taping the endotracheal tube to the patient. However, such devices do not allow for re-positioning or adjustment of the endotracheal tube within the device, and if tape or adhesives are used on the endotracheal tube, they are difficult to remove. With such devices or tape, adjustments of the endotracheal tube difficult and potentially dangerous for the patient.

Therefore, there is great need for an improved device, and related methods of treatment, to secure an endotracheal tube to a young patient (e.g., small children, newborn babies, etc.) to assist in the delivery of critical medical treatment, and for a device that maintains access to a young patient's mouth (e.g., a newborn baby's mouth). The present devices and methods meet these needs, and further provide for adjustable positioning of an endotracheal tube for secure placement in a patient.

Overview

The present disclosure relates to devices for securement of an endotracheal tube to a young patient's face or mouth (e.g., small child, newborn baby, etc.) that is adjustable, and methods for treatment using the same. In FIG. 1, and according to an exemplary embodiment, a clamping device system 100 is shown, wherein the system 100 includes a clamping device 101 with an endotracheal tube 210 installed through an aperture 120 of the clamping device 101. FIG. 2 displays the clamping device 101 of FIG. 1 in a closed position, without an endotracheal tube installed. The clamping device 101 may be formed from a single piece of plastic, or similar material and may be disposable. The clamping device 101 may be manufactured using additive manufacturing (e.g., 3D printing) or similar methods. In an exemplary embodiment, the clamping device 101 is about 6 cm long×5 mm wide. In some embodiments, the clamping device 101 may be curved or substantially non-planar, such that the clamping device is configured to be seated or located over a mouth of a patient (e.g., neonate baby).

In FIG. 1, the endotracheal tube 210 is shown in an installed configuration within the clamping device 101. The endotracheal tube 210 may be sold separately from the clamping device 101 or together with the clamping device 101. The endotracheal tube 210 may include a base section 201 having a top face 204, as shown in FIG. 1. From the top face 204 of the base section 201, a tube-shaped member 208 may extend from a center of the top face 204. An endotracheal tube 210 may be fluidly connected to the tube-shaped member 208 such that when oxygen (or other medical supplement used when intubating a patient for medical care) is pumped through a fluidly connected endotracheal tube adaptor 206, the oxygen may flow from adaptor section 206, into tube-shaped section 208, and into the endotracheal tube 210. The endotracheal tube 210 may be formed from medical grade plastic or similar material. The endotracheal tube 210 may be configured and dimensioned in a plurality of cross-sectional dimensions (e.g., diameters) such that the tube 210 may be inserted within the aperture 120 of the clamping device 101. It can be appreciated that the clamping device 101 may be used with the endotracheal tube 210 shown and described herein or alternatively the clamping device 101 may be used by any suitable commercially available endotracheal tube in the market. The clamping device 101 may, for example, be used with endotracheal tubes designed specifically for neonates or young adolescents. As will be described in greater detail, one or more passages or openings (e.g. passage 130) may generally provide for securing the device using an adhesive means 140 such as tape.

In FIG. 2, the clamping device 101 is shown in the closed, clamped position, and without the endotracheal tube 210. The clamping device 101 may be formed as an integral piece, unitary piece, from one or more materials (e.g., medical-grade plastic). The clamping device 101 may include two, opposed clamping arms 102 and 104 that may be clamped shut to hold or secure an endotracheal tube 210 within the aperture 120. The opposed clamping arms may be generally described as separate arms, portions, or halves split along an axis of elongation of the device 101, where the axis of elongation is oriented in the major or longest dimension of the device.

As shown in FIG. 2, a plurality of serrations 114 may be formed on an inner surface of the two, opposed clamping arms 102 and 104, such that when the two clamping arms 102 and 104 of the clamping device 101 are brought together, the serrations 114 close together to create a toothed-like grip. The serrations 114, if present, may assist in preventing movement of the arms in a closed state. In an alternative embodiment, the device does not have serrations 114. Engagement features 115 may also be formed within the aperture 120, in an exemplary embodiment, so as to secure or grip an endotracheal tube, as shown in FIG. 1. Engagement features 115 may include serrations, ridges, or other raised features that grip the endotracheal tube in a closed configuration. Ridges and serrations may be aligned in a concentric direction surrounding the aperture, in a direction parallel with the axis of the inserted endotracheal tube, diagonally, or in any other direction. Engagement features 115 may also include patterned or random raised features (for example, bumps), or alternatively a non-slip coating such as a rubberized coating. In an exemplary embodiment, the engagement features 115 may be substantially the size and shape at the plurality of serrations 114. In another exemplary embodiment, the engagement features 115 within the aperture may be different in size and shape from the serrations 114. The engagement features 115 may be formed such that they are not sharp enough to tear, rupture, or displace or otherwise disturb an installed endotracheal tube within the clamping device 101; however, they would be formed to optimally hold or secure the tube to prevent any slippage of the endotracheal tube upon installation in a young patient (e.g., neonate, small child, etc.).

In some exemplary embodiments, the clamping device 101 may include the serrations 114 and/or 115 along both arms and within the aperture. In an exemplary embodiment of the device 101, there may be six serrations per cm throughout the device (e.g., density of serrations).

A first end 106 of the clamping device 101 may include a closed, integrally formed hinge member 124. In an embodiment, the end 106 may be formed as substantially an “O-shaped” member, such that hinge member 124 is flexible to allow the first and second halves or arms of the device to open and close relative to one another. The end 106 may be formed integrally with the rest of the clamping device 101 such that the clamping arms 102 and 104 meet together at the end 106.

While an “O-shaped” end 106 is exemplary, the end 106 and hinge member 124 may take any shape or form so long as the end 106 functions as a hinge, and in some embodiments generally provides for a passage 130, alternatively referred to as an opening for an adhesive means 140. In an embodiment, the hinge member 124 defines passage 130. In an alternative embodiment, a passage 130 is provided or disposed on an exterior portion of the end 106 such that the hinge member 124 does not define the passage 130. In an alternative embodiment, end 106 includes an adaptor or other means for coupling with an adhesive means 140.

The clamping device 101 may also include an opposed second end 108, as shown in FIGS. 2 and 3, that may be releasably opened (see FIG. 3) and closed (see FIG. 2) using a locking mechanism 109, alternatively referred to as a releasable securement mechanism. In an exemplary embodiment, the locking mechanism 109 may include locking members 110 and 112. The locking member 110 is disposed on clamping arm 102 and the locking member 112 is disposed on clamping arm 104. The locking members 110 and 112 are integrally formed within their respective clamping arms 102 and 104, respectively. During operation of the clamping device 101, when a user (e.g., nurse, doctor, or individual charged with the management and/or installation of the endotracheal tube on a patient) closes or brings the two clamping arms 102 and 104 together, the clamping device 101 may be locked or fastened using the locking mechanism 109 at the end 108. That is, the arms may be retained in one or more positions relative to one another such that they will not move unless tightened further or released.

Exemplary locking mechanisms 109 are depicted in FIGS. 4A and 4B. In an embodiment, as depicted in FIG. 4A, each of the locking members 110 and 112 include teeth 113 which may be evenly spaced and which may engage when they are moved past one another during closure of locking member 110 with locking member 112. In an alternative embodiment, as depicted in FIG. 4B, one locking member (110 or 112) includes teeth 113a and the other locking member includes corresponding grooves which are configured and spaced to engage with the teeth. Generally, when an endotracheal tube 210 is inserted into aperture 120 of the device, some pressure will need to be applied to secure locking members 110 and 112 by teeth 113 or by teeth/grooves 113a/113b, and the teeth or teeth/grooves will generally remain engaged until the mechanism is released. The locking mechanism 109 is releasable and generally includes a means for disengaging the locking members 110 and 112 to separate the arms 102 and 104 of the device. In an embodiment, the means for disengaging is a pull tab 119 which allows locking member 112 to be pulled away from locking member 110 until their teeth 113 or teeth/grooves 113a/113b disengage to allow the arms 102 and 104 of the device to separate.

In an embodiment, the teeth 113 or teeth/grooves 113a/113b may take any shape or form so long as they hold the device 101 in a closed position to secure the endotracheal tube 210. In an embodiment, there are a plurality of teeth 113 or teeth/grooves 113a/113b so that the locking members 110 and 112 may be closed in a plurality of different positions so as to apply various gripping pressure on the endotracheal tube. In an embodiment, the locking members 110 and 112 each contain between 2 to 8 teeth, or 2 to 8 teeth and 2 to 8 corresponding grooves. In various alternative embodiments, teeth and/or grooves may be disposed on either or both sides of the locking members 110 and 112 provided that the device is configured and dimensioned such that the teeth 113 or teeth/grooves 113a/113b of the locking members 110 and 112 will interfere so as to releasably lock the device in a closed position to secure an endotracheal tube 210. In a closed position, the locking mechanism may provide a passage 131 for an adhesive means 140, such that each end of the device contains such a passage for securing the device to the face of a patient. It can be appreciated that the locking mechanisms of FIG. 4A and FIG. 4B are exemplary and any suitable, releasable locking mechanism is contemplated.

In some exemplary embodiments, the clamping device 101 may be formed with alternative locking mechanisms other than the locking mechanism 109 alluded to above. For example, in an exemplary embodiment the “closure” or locking mechanism to secure the clamping arms 102 and 104 may be formed with an “O” closure with a “button” that may be depressed in order to have opposing “O” click in place over it, as shown in FIG. 5. The button 300 generally may be inserted into overlapping or eclipsed button closures 301 when the ends 332 and 334 of the device are closed together. In a closed position, the arms 302 and 304 will be pulled together so as to secure the endotracheal tube in the aperture of the device as described herein. The button may be a plain button closure 300, or may alternatively be a button 310 with a loop 315 on the back, or may alternatively be a button 320 with a loop 325 located at a side. A loop 315 or 325 is generally useful for providing a passage for a securement means as described herein, such as a cloth tape. The button closure is releasable if the button is removed from the eclipsed closures 301.

In yet another exemplary embodiment, the “O” shapes, described above, may be sized in a compatible manner in order to slide together and click in place with or without a flexible tooth/groove closure to hold both “O” shapes together. In yet another exemplary embodiment, the ends may have notches or holes for using wire or an adhesive means to secure the ends in a closed position. In yet another exemplary embodiment, the ends may interfere or be closed together in any manner.

In an exemplary embodiment, the device may have a curved profile, of the device may be generally arcuate. Alternatively, at least one outer surface may be generally arcuate or curved, meaning that in addition to the required curved outer surface, any other portion of the device, including the entire device, may be curved. The at least one outer surface is generally curved so as to conform with a shape of a mouth region of a patient's face for comfort and improved stability of the device in a secured state.

An exemplary arcuate or curved device is show in in FIG. 6. The curvature of the at least one face, or in this case of the entire device, is generally along an axis 121 of the aperture 120/inserted endotracheal tube 210. That is, if the endotracheal tube 210 is inserted from the top of FIG. 6 into the top of the aperture, the ends 106 and 108 will generally curve away from the top of the aperture. The curvature may be alternatively described as generally parallel with the axis of elongation of the device, because the longest axis (i.e. axis of elongation) of the device will become longer when the device is curved compared to a straight or linear device. It is intended that the axis of elongation can be a curved axis when the device is arcuate or curved.

The curvature of the device may be defined in various manners. For example, as shown in FIG. 6, the device may be placed on a vertical axis 121 which passes through the center of the aperture with the ends 106 and 108 being generally horizontal. An x-axis may be placed at a vertical center of the aperture and a diagonal axis may be placed to bisect an end (end 106 in this case). An angle α may then be defined as the angle between the x-axis and the diagonal axis to provide an “angular curvature”. In an embodiment, the angular curvature of the device (i.e. angle α) is about 1 degree to about 30 degrees. In an embodiment, angle α is about 5 degrees to about 20 degrees. In an embodiment, angle α is about 5 degrees to about 15 degrees.

In alternative embodiments, the curvature may also be defined by approximation of the at least one arcuate surface (or entire device in some cases) to a circle. For a circle, the curvature may be defined by the inverse of the radius (e.g. in mm) with units of rad/mm. In an embodiment, the curvature is from about 0.04 rad/mm to about 0.001 rad/mm. In an alternative embodiment, the curvature is from about 0.02 rad/mm to about 0.005 rad/mm. In some alternative embodiments where the curvature is approximated by a circle, the dimensions may be alternatively or additionally defined by a chord of the circle. In an embodiment, the chord is from about 2 cm to about 8 cm, or from about 4 cm to about 7 cm. Per the standard geometric definition, a “chord” is a straight line segment whose endpoints both lie on a circular arc.

In alternative embodiments, the locking mechanism 109 may include any features useful for retaining locking members 110 and 112 in a closed state for device 101 to secure an endotracheal tube. For example, in an embodiment, a tongue-and-groove type of retaining feature 113c may be included. The tongue may be retained in the groove by friction or by one or more other features in the tongue or groove which releasably lock the locking members 110 and 112 in a closed state. In another embodiment, an overlapping type of retaining feature 113d may be included. The overlapping features may be retained by tension from, for example, locking member 110 being stretched outward for its overlapping feature to overlap with the corresponding feature on locking member 112. Alternatively, the overlapping retaining feature(s) 113d may include one or more additional features which releasably lock the locking members 110 and 112 in a closed state. In an alternative embodiment, overlapping feature 113d may be alternatively or additionally secured in a closed state with an adhesive means such as tape. It can be appreciated that various adaptations of the locking mechanisms 109 are within the scope of the present disclosure.

In an exemplary embodiment, the endotracheal tube that is to be secured or held by the clamping device 101, taught herein, may vary in size (e.g., diameter of the endotracheal tube may change) depending on the weight and/or body mass index of the patient (e.g., larger or smaller newborn babies). The diameter of the aperture 120, for example, may correspond with the following patient body weights:

• • 4.0 mm for >3 kg;
  • 3.5 mm for 2-3 kg;
  • 3.0 mm for 1-2 kg; or
  • 2.5 mm for <1 kg.

In an exemplary embodiment, each size of the clamping device 101 may be formed using a different color, and each size may be slightly bigger to accommodate a larger infant.

In some exemplary embodiments, the clamping device 101 may be manufactured in four (4) different sizes to accommodate four (4) different neonatal size groups. The table below is an example of the four different neonatal size groups:

Sizes	Length	Color	ETT Hole Size
