DETAILED DESCRIPTION OF THE INVENTION

[0027] In accordance with the objectives presented through the brief description, the present patent application shows an ENDOTRACHEAL TUBE FASTENING APPARATUS (1), as showed in the plan views of FIG. 1, FIG. 2 and FIG. 3, comprising an adhesive layer (2) and a hole (3) for the passage of an endotracheal tube (4), wherein the adhesive layer (2) is divided into two portions, one smaller upper (8) and one larger lower (8′) part and has enough dimension to allow its fastening, in a simultaneous manner, on the upper part of the lip and on the mental region of a patient;

[0028] wherein at the end (2a), facing the upper lip, of the apparatus (1) there is a cutout (7) extending to the hole (3), and an opening (3a) is formed in it, also facing the upper lip, and divides the smaller upper (8) portion of the apparatus (1) into two upper attachments (8a, 8b);

[0029] wherein there is also a cutout (7′) in the larger lower (8′) portion of the adhesive layer (2), starting at the end (2b), facing the mental region of the apparatus (1) and is large enough to enable the adhesion of layer (2) on the skin and keep intact the contour (3b) also facing the mental region of the hole (3), so that the cutout (7′) also divides the larger lower portion (8′) into two lower attachments (8′a, 8′b);

[0030] said hole (3) has, on its sides, two flaps (5a, 5b), one on each side, the said flaps (5a, 5b) having each a first free end (6) and a second end (6′) adjacent to the hole (3), attached to the adhesive layer (2); the said flaps (5a, 5b) can be folded upwards, forming a channel (5c) and are also formed by an adhesive layer (5).

[0031] Referring also to FIGS. 1, 2, and 3, in an embodiment of the apparatus of the present invention, the adhesive layer (2) has a beveled rectangular shape, with the bevels of the layer (2) located at the end (2b) of the larger lower portion (8′), facing the region to be fixed on the mental region and, therefore, opposite to the end (2a) of the apparatus (1). The adhesive layer (2) also has a hole (3) applied in such a way that, when applying the apparatus (1) to a patient, the hole (3) is positioned at the center of the mouth.

[0032] In another embodiment of the apparatus (1), as it can also be seen in FIGS. 1, 2, and 3, the cutout (7, 7′) is positioned in the middle region of the upper (2a) and lower (2b) extremities of the apparatus (1) and towards the center of the hole (3).

[0033] The size of the adhesive layer (2), as mentioned, must be such that it can be simultaneously attached above the patient's upper lip, and on his/her mental region (chin), considering previously that several sizes must be predicted taking into account the possibility of intubation of premature babies or adults, having the most diverse body and facial structures. In this way, the apparatus (1) of the present invention can be made in different sizes in order to allow the application in a great diversity of patients needing intubation for any surgical procedure that requires advanced life support.

[0034] The size of the hole (3), in the same way as the size of the adhesive layer (2), must be considered according to the different diameters of existing endotracheal tubes, which must be chosen taking into account the patient's height, physiological condition and age. In this way, the apparatus (1) can be made with endotracheal tube passage holes of different diameters, also allowing its use in surgeries of premature babies, newborns, children and adults with the most diverse body structures.

[0035] Thus, the same size of the layer (2) can be made with different sizes of hole (3), made to house the diameters of endotracheal tubes available in the market.

[0036] Due to its innovative shape, and different from fastener apparatuses comprising an adhesive layer of the state of the art, the method of application of the apparatus (1) of the present invention is different and equally advantageous, enabling the endotracheal tube to be securely and easily fasten, in addition to ensuring its withdrawn without causing injuries patient's extubation.

[0037] The application comprises the following steps, which are illustrated in FIG. 4:

[0038] to pass the endotracheal tube (4) through the hole (3) of the apparatus (1), as shown in FIG. 4(a). FIG. 6 illustrates an endotracheal tube (4) wrapped by the apparatus (1) without being applied to a patient's face for a better understanding of how the tube (4) passes through the hole (3). Still with respect to FIG. 6, it can be seen how the opening (3a), not shown in the figure, but shown in FIG. 3, facing the lower lip, of the hole (3) opens, this opening being formed by the cutout (7) for fitting the tube while the contour (3b), below the tube and also not referenced in this figure, keeps intact and supports the tube (4);

[0039] to position the two upper attachments (8a, 8b) of the apparatus (1) towards the sides of the nose and above the upper lip of the patient, as shown in FIGS. 4(a) and 4(b);

[0040] to remove partially the second layer (2′) from each upper attachments (8a, 8b) and attach them to the skin, as can be seen in FIG. 4(b);

[0041] after attaching the smaller upper (8) portion of the apparatus (1) to the skin, to remove the remainder of the second layer (2′) and gradually attach the adhesive layer (2) on both sides of the mouth and on the mental region, as can be seen in FIG. 4(c); and

[0042] after the adhesive layer (2) of the apparatus (1) is completely attached to the patient's skin, to remove the protective layer (5′) from the flaps (5a, 5b) and attach them to the endotracheal tube (4), as can be seen in FIG. 4(d). In FIG. 4(d), it can also be seen the lower attachment (8′b) already attached to the patient's skin. FIG. 4(e) shows the apparatus (1) fully installed, with the two flaps (5a, 5b) fixed to the tube (4) and the upper attachment (8b) completely fastened to the skin.

[0043] The withdraw of the endotracheal tube, illustrated in FIG. 5, is also facilitated by the shape of the apparatus (1), made by first detaching the flaps (5a, 5b) from the tube (4), undoing, thus, the channel (5c); then, the two upper attachments (8a, 8b) of the apparatus (1) while the two lower attachments (8′a, 8′b) still keep attached to the patient's mental region, ensuring the stability of the tube during the handling, since it is not necessary to handle it to withdraw the apparatus (1).

[0044] According to the aforementioned and in line with an embodiment of the apparatus (1) of the present invention, the apparatus (1) when applied to the face of a patient submitted to a surgery that requires advances life support, completely covers the oral cavity, isolating it and reducing the risk of contamination during the procedure, with the hole (3) positioned at the center of the mouth.

[0045] In another embodiment of the apparatus (1), as shown in FIG. 7, the flaps (5a, 5b) are attached to the endotracheal tube (4). For the flaps (5a, 5b) to be attached to the tube (4), the second ends (6′) of the flaps (5a, 5b) are folded upwards, forming an adhesive channel (5c), causing said flaps (5a, 5b), and consequently the channel (5c), to be perpendicular to the adhesive layer (2), as shown in FIG. 8(a, b and c).

[0046] In another embodiment of the apparatus (1), also illustrated in FIG. 7, the flaps (5a, 5b) are attached to the endotracheal tube (4) in the longitudinal direction of said tube (4) and are parallel to each other.

[0047] In a last but one embodiment of the apparatus (1), the adhesive layer (2, 5) has a second protection layer (2′, 5′) in the same shape and size as the protected adhesive layer (2, 5). In a last embodiment of the apparatus (1), the second protection layer (2′) is divided into two parts, in the longitudinal direction, to facilitate the handling of the apparatus (1) during application, as can be seen in FIG. 9.

[0048] The present patent application also shows the use of an apparatus (1), as defined herein, for fastening an endotracheal tube (4) during surgical procedures that make it necessary to provide the patient with advanced life support.

[0049] It should be understood the present specification does not limit the application to the details described herein and the invention is capable of other embodiments and to be practiced or performed in a variety of ways within the scope of the claims. Although specific terms have been used, these terms should be construed in a generic and descriptive sense, and not for the purpose of limitation.
