DETAILED DESCRIPTION OF THE INVENTION

[0032] The present invention describes an Endotracheal Tube Barrier Kit with sealing cap attached to clamp for use in advanced airway management procedures consisting of two devices, one for sealing and one for “clamping” the tube, coupled together. The kit consists of the following components: sealing device (1) and occluder clamp (2). Illustratively, to understand more clearly the use of the Barrier Kit, the tube devices (3) are also shown, connector (4) and guide wire (5), which are components to which the barrier kit is applied.

[0033] The first device in the barrier kit is the device for sealing (1) gases, aerosols, droplets, and secretions from the endotracheal tube. Such a sealing device is composed of flexible material, preferably selected from the group containing flexible elastomer material, latex, rubber, or flexible polyurethane, ensuring elastic properties that are fundamental to sealing. With a circumferential shape of about 20 mm in diameter and approximately 10 mm high in the central part, it has a virtual central hole (A) for the passage of the guide wire (5) identified with a relief different from the main body to facilitate its identification, and a flap, called the removal ear, made of the same material, to facilitate the removal, extraction, of the device during intubation.

[0034] The sealing device (1) is used attached to the larger hole in the connector for the mechanical ventilation circuit present on the tubes and/or probes and/or endotracheal catheters, and a second device for “clamping” or occluding the tubes and/or probes and/or endotracheal catheters for gases, aerosols, droplets and patient secretions, which may be used on the body of the tubes and/or probes and/or endotracheal catheters attached near the connector for the mechanical ventilation circuit or away from it.

[0035] FIG. 1 shows the first device, sealing device (1) attached to the second device, occluder clamp device (2).

[0036] FIG. 2 shows a perspective image of the sealing device (1).

[0037] FIG. 3 shows a sectional view of the sealing device (1). Its elastic composition allows its body to be deformed in such a way as to allow the guide wire, of greater thickness, to penetrate through the central virtual orifice (A) (Detail A), sealing the exit of gases, aerosols, droplets, and secretions by the elastic pressure that the material makes against the wall of the guide wire. Its elastic composition is also used to promote the sealing of the connector by deformation of the inner walls (B) (Detail B). When the sealing device (1) is fitted to the connector, the inner walls (B) deform and press against the connector wall, thus sealing takes place.

[0038] The second device, called the endotracheal tube occluder clamp (2) (FIG. 4), is confectioned in a single body with resistant plastic material, preferably selected from the group containing poly lactic acid plastic (PLA) and high density polyethylene (HDPE), presenting central holes through which the endotracheal tube passes, and having a fin (C) with a cylindrical shape on one of its sides, in order to be fitted into a gap formed by two other fins (C), also cylindrical, on the opposite side. This structuring allows atraumatic “clamping” of the tube, with a greater deformation angle than that of the tube, with the possibility of sealing up to 100% of its lumen when in use, as shown in FIG. 4.

[0039] FIG. 5 shows the side view of the occluder clamp device (2), highlighting the fins (C) (Detail C) used to press the tube and cause obstruction to the passage of gases, aerosols, droplets, and secretions inside the tube. After actuating the device, the force is directed through the upper fin (C) by pressing the tube into the two fins (C) at the bottom, promoting a larger area of obstruction within the tube, the arrows in Detail C indicate the direction of the forces on the fins (C).

[0040] FIG. 6 shows the occluder clamp device (2) in a new perspective, highlighting the support for fitting (D) of the sealing device (1) (detail D) to allow the two devices to connect and form the endotracheal tube barrier kit with sealing cap attached to the clamp for use in advanced airway management procedures.

[0041] FIG. 7 shows a new side view of the occluder clamp device, and highlights the various stages for adjusting the degree of occlusion (E) (detail E), which allows its more adequate and precise use in the various existing pipe diameters, and enables its correct adjustment until the complete occlusion of the pipe when necessary.

[0042] FIG. 8, from a posterior view of the occluder clamp, highlights the finger fitting (F) (detail F), This makes the device more ergonomic and allows for more comfort, and improves the mechanics of its use.

[0043] FIGS. 9, 10 and 11 show how the Barrier Kit for gases, aerosols, droplets and secretions on the endotracheal tube for advanced airway management should be assembled.

[0044] FIG. 9 demonstrates the assembly of the kit on the endotracheal tube. With the tube assembly (3) and endotracheal tube connector (4) disassembled and the devices in the kit disconnected, use the two center holes at the ends of the occluder clamp (2) to pass the tube (3) through its body, positioning the tube between the fins (C) of the device. The connector (4) is normally made of plastic material and has a diameter of approximately 15 mm as standard.

[0045] Then the smallest hole of the connector (4) is pressed against the tube (3), and the parts are joined together. Finally the sealing device (1) is placed in the larger hole of the connector (4). The arrows indicate the direction of placement of the parts.

[0046] FIG. 10 shows the correct direction of flow of the guide wire (5) through the system: tube (3), connector (4), sealing device (1) and occluder clamp device (2).

[0047] The sealing device (1) contains a recess that highlights the central part where it contains the virtual hole for the guide wire (5) to pass through, as shown in FIGS. 2 and 3. The guide wire is used to help obtain a better positioning of the tube in the patient's airway, even facilitating its identification; it is about 5 mm in diameter and may be composed of several materials.

[0048] FIG. 11 shows all the device parts—(1) and (2)—fixed in their positions, demonstrating the complete system assembled and prepared for the intubation procedure—including the tube devices (3), connector (4) and guide wire (5), not belonging to the set of the proposed invention.
