Background Art

[0003] The present disclosure generally relates to medical tube devices that can be used, for example, in intubation, and more specifically, to devices for holding an endotracheal tube or other intubation devices in a patient.

[0004] Intubation tubes such as endotracheal tubes are inserted into patients for various reasons. In the case of an endotracheal tube, the tube is inserted to secure and maintain the patient's airway during resuscitation, anesthesia, and other critical care procedures. The endotracheal tube helps deliver air to patients who are unable to breathe on their own. The endotracheal tube is installed before surgery or used for critically ill patients who require long - term respiratory assistance. After intubation, the endotracheal tube must be fixed in place to prevent it from moving for up to several days.

[0005] To properly fix an intubation tube to a patient, known designs disclose various fixing components. However, these fixing components have various drawbacks. Therefore, an improved intubation tube holder system is required.

[Figure 19] For example, Figure 1 shows isometric views of the top, front, and right side of the holder system used to hold an intubation tube, etc. [Modes for carrying out the invention]

[0029] The following description and accompanying drawings disclose various embodiments or configurations of a holder system comprising a retaining assembly, a head strap, and several additional components. While embodiments of the holder system are disclosed in the case of fixing or holding an endotracheal tube, the concepts related to embodiments of the holder system can be applied to a wide range of products. For example, the holder system can be used to fix or hold various types of tubes, medical devices, and products, and is not limited to fixing or holding endotracheal tubes, including endotracheal tubes.

[0030] Referring to the drawings, Figures 1-8 show an intubation tube holder system 100 for fixing or holding a tube 102 and other components (see Figure 19). As described below, the holder system 100 can be used to fix an endotracheal tube to a patient as a non-limiting example. Thus, although the holder system 100 is sometimes referred to as an endotracheal tube holder system, the use of the system as such is not limited to fixing only endotracheal tubes, but also applies to fixing other tubes, devices, or components that need to be fixed to the patient's head or near an opening such as the mouth or nose. Therefore, the terms "tube holder," "tube," or "endotracheal tube" are not limited to the system 100 or other configurations described in this application.

[0031] Specifically referring to Figures 1 and 2, the system 100 comprises a retaining assembly 104 and a head strap 106. The retaining assembly 104 is configured to be fixed to the tube 102 (see Figure 19), and the head strap 106 is configured to be positioned around the patient's head. As will be described in detail below, the head strap 106 can be a four-point head strap fixed at four points to the retaining assembly 104 to reinforce the fixation of the component (tube, etc.) and prevent displacement of the component (see Figure 19).

[0032] Referring to Figures 1 and 2, the retaining assembly 104 comprises a retainer 110, a face support 112, a first pad 114, a second pad 116, a tube holder 118, and a tube strap 120. The retainer 110 may include a bar 130 extending from a first cheek bracket 132 to a second cheek bracket 134. The retainer 110 may be transparent or translucent and may be made from plastic or polymer material. In some non-limiting examples, the retainer 110 may be opaque rather than transparent or translucent. The bar 130 is connected to the first cheek bracket 132 and the second cheek bracket 134 at a hinge 136 as shown in Figures 1 and 2, and the overall shape of the retainer 110 when viewed from above is arched (see Figure 7). As will be described in detail below, the bar 130, hinge 136, and cheek brackets 132, 134 can be bent, slightly deformed, and / or contoured to be fixed to the patient's face. Thus, the material of the retainer 110 can be flexible and bent or formed into several different configurations to fit the patient.

[0033] Continuing to refer to Figures 1 and 2, the bar 130 is arch-shaped and includes a track 140 extending from the front side 142 of the bar 130. The track 140 can be provided with a number of recesses 144 extending from the first end 146 to the second end 148 of the track 140. A track wall 150 is positioned adjacent to the first end 146 of the track 140, and a track hinge 152 is positioned at the second end 148 of the track 140. A contact portion 154 extends outward from the front side 142 of the bar 130 adjacent to the track hinge 152 (see Figure 7). As will be described in detail below, the track 140 is configured to fix a tube holder 118 to the holder 110 between the track wall 150 and the track hinge 152. As shown in Figures 1 and 2, the track 140 extends outward from the bar 130, forming an upper track cavity 156 and a lower track cavity 158 between the track 140 and the bar 130. The upper track cavity 156 and the lower track cavity 158 extend between the track wall 150 and the track hinge 152.

[0034] Continuing to refer to Figures 1 and 2, the first cheek bracket 132 and the second cheek bracket 134 are positioned at opposite ends of the bar 130 and are mirror images of each other. Each of the first and second cheek brackets 132 and 134 comprises a bracket body 170 with a recess, a frame 172, a first strap loop 174, and a second strap loop 176. The bracket body 170 of the first cheek bracket 132 is fixed to the first pad 114, and the bracket body 170 of the second cheek bracket 134 is fixed to the second pad 116. The frame 172 provides additional support for the first cheek bracket 132 and the second cheek bracket 134, and the first strap loop 174 and the second strap loop 176 are configured to be fixed to the head strap 106. As described below, the first strap loop 174 and the second strap loop 176 are fixed to the head strap 106 and are positioned to reduce the drag applied to the tube 102, which could cause tube displacement, accidental extubation, or increased care costs. Therefore, it is advantageous to position the first strap loop 174 and the second strap loop 176 so that the head strap 106 can properly secure the retention assembly 104 to the patient's face. The first and second strap loops 174 and 176 form a racetrack shape. However, in some non-limiting examples, the first strap loop 174 and the second strap loop 176 can be any shape, such as elliptical, circular, rectangular, square, triangular, or polygonal. Also, in some non-limiting examples, more than two strap loops 174 and 176 can be provided on each of the first and second cheek brackets 132 and 134. For example, in some non-limiting examples, the first and second cheek brackets 132, 134 may be provided with three, four, or five strap loops 174, 176. Furthermore, in some non-limiting examples, the first and second cheek brackets 132, 134 may have just one strap loop.

[0035] Continuing to refer to Figures 1 and 2, the first pad 114 and the second pad 116 are mirror images of each other, and release tabs 182 are fixed to the rear side 184 of each of the first and second pads 114 and 116. The first pad 114 and the second pad 116 are made of hydrocolloid dressing material, and an adhesive (not shown) is provided on the rear side 184 of each of the pads 114 and 116. This adhesive is configured to fix the first pad 114 and the second pad 116 to the patient's face or cheek when in use. The first pad 114 and the second pad 116 can be flat or can be contoured to match the shape of the patient's face and / or cheek. As described below, the first pad 114 and the second pad 116 are transparent or translucent. Therefore, the patient's face or cheek can be seen, or partially seen, through the first pad 114 and the second pad 116. This allows healthcare professionals to see the patient's face or cheeks beneath the first pad 114 and the second pad 116. If the user's skin becomes irritated or red during use, healthcare professionals can see through the first pad 114 and the second pad 116 and adjust the system 100 accordingly or provide a new system 100, thereby providing further care to the patient using transparent or translucent pads 114, 116. In some non-limiting cases, the first pad 114 and the second pad 116 can be opaque. During use, healthcare professionals can peel off the release tabs 182 from the first and second pads 114, 116 to expose the adhesive attached to the pads 114, 116. The first pad 114 and the second pad 116 can then be attached to the patient's face or cheeks to secure the retaining assembly 104 to the patient's face.

[0036] Continuing to refer to Figures 1 and 2, the face support 112 extends from the rear side 190 of the bar 130. The face support 112 can be formed from foam material. However, in some non-limiting examples, the face support 112 can be formed from plastic or fabric material. The overall shape of the face support 112 is U-shaped and is configured to be positioned directly above the patient's mouth when in use. Ideally, the face support 112 is formed from a flexible or gentle material to minimize any discomfort to the patient.

[0037] Continuing to refer to Figures 1 and 2, the tube holder 118 comprises a tube holder body 202 fixed to a bite block 204. In some non-limiting examples, the tube holder 118 may not include the bite block 204. The tube holder 118, like the retainer 110, can be transparent or translucent and can be formed from the same or different plastic or polymer material. As shown in Figures 1 and 2, the tube strap 120 extends outward from the tube holder 118 and is fixed within a slot 206 of the tube holder 118. The tube strap 120 has a first end 210 and a second end 212. The first end 210 of the tube strap 120 is a free end, and the second end 212 is fixed within the slot 206. Specifically, the second end 212 of the tube strap 120 is thicker than the first end 210 of the tube strap 120, and the second end 212 of the tube strap 120 is press-fitted into the slot 206 of the tube holder 118, so that the thicker second end 212 of the tube strap 120 does not slide through the slot 206 of the tube holder 118. The tube strap 120 is equipped with a plurality of ribs 214 that help a healthcare professional or person / user to grasp and hold the tube strap 120 and apply the system 100 to a patient. In particular, each of the plurality of ribs 214 is formed in an arch shape. By making the plurality of ribs 214 arched, the grip of the tube strap 120 is improved compared to straight ribs. This is because, with straight ribs, the fingertips of the user or healthcare professional tend to slip on the ribs, whereas the arched curve prevents the fingertips from slipping and allows the fingertips to fit into the arched curve, improving grip in various hand positions and improving ease of use. The radius of each of the multiple ribs 214 is approximately equal to the diameter of a fingertip. In some non-limiting examples, the multiple ribs 214 may be small bumps, small circular ribs and / or other protrusions. Furthermore, in some non-limiting examples, the multiple ribs 214 may be perforations formed in the tube strap 120 rather than ribs protruding from the tube strap 120.As shown in Figure 2, the tube strap 120 also includes a tube strap release tab 216 covered with an adhesive (not shown). As will be described in detail below, the tube strap 120 is configured to wrap around the tube 102 to secure the tube 102 to the system 100 (see Figure 19).

[0038] Continuing to refer to Figures 1 and 2, the head strap 106 is fixed to the retaining assembly 104 at four points. Specifically, it is fixed at the first strap loop portion 174 and the second strap loop portion 176 of the first and second cheek brackets 132 and 134, respectively. The head strap 106 comprises an upper strap 220 and a lower strap 222. The upper strap 220 is configured to be fixed to the second strap loop portion 176 of the first and second cheek brackets 132 and 134, respectively, and the lower strap 222 is configured to be fixed to the first strap loop portion 174 of the first and second cheek brackets 132 and 134, respectively. The upper strap 220 is connected to the lower strap 222 by a support strap 224. The upper strap 220, the lower strap 222, and the support strap 224 constitute the head strap 106 and also form a plurality of openings 226 of the head strap 106. The head strap 106 is configured to help secure the system 100 to the patient's head more effectively by preventing the tube 102 from sagging during use. The upper strap 220 helps to position the tube 102 better than in a single-strap configuration and can be very useful for patients with facial hair. Thus, the head strap 106 increases the number of strap connection points to the retaining assembly 104, reducing the resistance on the tube 102 and preventing tube slippage, accidental extubation, and increased care costs. In some non-limiting examples, the system 100 may have a two-point connection configuration. In other words, in some non-limiting examples, the head strap 106 may be secured to only two of the four strap loops 174, 176, rather than all four.

[0039] Referring now to Figure 3, the front view of system 100 is shown. As shown in Figure 3, the first strap loop 174 of the first cheek bracket 132 has axis A1, the second strap loop 176 of the first cheek bracket 132 has axis A2, the second strap loop 176 of the second cheek bracket 134 has axis A3, and the first strap loop 174 of the second cheek bracket 134 has axis A4. Axes A1, A2, A3, and A4 extend longitudinally through the centers of the first and second strap loops 174 and 176, respectively. As shown in Figure 3, axes A1 and A4 are substantially perpendicular to the bar 130. By convention, axes A2 and A3 in Figure 3 are inclined or at an angle with respect to the bar 130 and axes A1 and A4.

[0040] Continuing to refer to Figure 3, the first axis A1 and the second axis A2 form an angle B1. In some non-restrictive examples, angle B1 is approximately 1° to approximately 179°, or approximately 20° to approximately 160°, or approximately 90° to approximately 180°, or approximately 91° to approximately 179°, or approximately 95° to approximately 170°, or approximately 100° to approximately 170°, or approximately 100° to approximately 130°, or approximately 100° to approximately 120°, or approximately 105° to approximately 115°, or approximately 110°, or at least approximately 91°, or at least approximately 95°, or at least approximately 100°, or at least approximately 105°, or at least approximately 110°. In some non-restrictive examples, angle B1 is not 90°, i.e., the first axis A1 and the second axis A2 are not perpendicular to each other.

[0041] Continuing to refer to Figure 3, the third axis A3 and the fourth axis A4 form an angle B2. In some non-restrictive examples, angle B2 is approximately 1° to approximately 179°, or approximately 20° to approximately 160°, or approximately 90° to approximately 180°, or approximately 91° to approximately 179°, or approximately 95° to approximately 170°, or approximately 100° to approximately 170°, or approximately 100° to approximately 130°, or approximately 100° to approximately 120°, or approximately 105° to approximately 115°, or approximately 110°, or at least approximately 91°, or at least approximately 95°, or at least approximately 100°, or at least approximately 105°, or at least approximately 110°. In some non-restrictive examples, angle B2 is not 90°, i.e., the third axis A3 and the fourth axis A4 are not perpendicular to each other.

[0042] Next, referring to Figure 4, which is a rear view of system 100 and shows the head strap 106 in more detail. As shown in Figure 4, the upper strap 220 has a first upper strap end 230 and a second upper strap end 232, and the lower strap 222 has a first lower strap end 234 and a second lower strap end 236. Each strap end 230, 232, 234, and 236 is provided with a strap tab 238 and a fixing part 240 positioned on the strap tab 238 (see Figure 8). As shown in Figures 3 and 4, the fixing part 240 is configured to fix each strap end 230, 232, 234, and 236 (and the strap tab 238) to the corresponding straps 220 and 222, respectively. In other words, when in use, the first upper strap end 230 of the upper strap 220 is passed through the second strap loop 176 of the first cheek bracket 132 and fixed to a part of the upper strap 220. Similarly, the second upper strap end 232 of the upper strap 220 is passed through the second strap loop 176 of the second cheek bracket 134 and fixed to a part of the upper strap 220. The first lower strap end 234 of the lower strap 222 is passed through the first strap loop 174 of the first cheek bracket 132 and fixed to a part of the lower strap 222, and the second lower strap end 236 of the lower strap 222 is passed through the first strap loop 174 of the second cheek bracket 134 and fixed to a part of the lower strap 222. Therefore, the fixing portion 240 of each upper strap end 230, 232 is configured to fix the upper strap end 230, 232 when it returns to the upper strap 220, and the fixing portion 240 of each lower strap end 234, 236 is configured to fix the lower strap end 234, 236 when it returns to the lower strap 222. In this way, the user or healthcare professional can adjust the head strap 106 at the four contact points with the retaining assembly using the upper and lower strap ends 230, 232, 234, 236 to fit and secure the system 100 to the patient's head.In some non-limiting examples, the fastening portion 240 may be Velcro® or a similar fastening member that is fixed to a portion of the upper strap 220 and the lower strap 222. Thus, in such embodiments, the head strap 106 or a portion of the head strap 106 may be made from a material that is fixed to the fastening portion 240 of each strap tab 238. Furthermore, in some non-limiting examples, the fastening portion 240 may be a buckle (Cinchlock®, Ladderlock, and / or Triglide), adhesive, and slide-release buckle that fastens the upper and lower strap ends 230, 232, 234, 236 to the head strap 106.

[0043] As described below, Figures 1-8 show how the upper and lower strap ends 230, 232, 234, and 236 are fixed to the outer / outer end of the head strap 106. However, in some non-limiting examples, the head strap 106 can be reversed and the upper and lower strap ends 230, 232, 234, and 236 can be fixed to the inner / inner end of the head strap 106. Furthermore, the outer / outer end of the head strap 106 and / or the inner / inner end of the head strap # can be provided with a material that is fixed to a fixing part 240, such as a Velcro® connector.

[0044] Next, referring to Figures 5 and 6, these are the right and left side views of the system, respectively. In Figures 5 and 6, the contours of the first and second cheek brackets 132, 134 and the contours of the first and second pads 114, 116 can be seen in more detail. As described below, the first strap loop 174 and the second strap loop 176 of the second cheek bracket 134 are offset from each other in all three dimensions (see Figure 5), and the first strap loop 174 and the second strap loop 176 of the first cheek bracket 132 are offset from each other in all three dimensions (see Figure 5).

[0045] Next, referring to Figures 7 and 8, these are top and bottom views, respectively, illustrating the system 100 in detail. As shown in Figures 7 and 8, the retaining assembly 104 is wing-shaped and, when viewed from the front, is generally concave. As described above, the shape of the retaining assembly 104 is arch-shaped or wing-shaped, allowing it to fit the contour of the patient's face. Furthermore, as also described above, the retaining assembly 104 is flexible so that it can be fixed to the patient's face.

[0046] Referring to Figures 1-8, the method for securing the system 100 to the patient is described below. Specifically, first, the head strap 106 of the system 100 is placed over the patient's head. After the head strap 106 is placed over the patient's head, the user or healthcare professional can adjust the head strap 106 to peel off the release tabs 182 of the first pad 114 and the second pad 116 and attach the pads 114 and 116 to the patient's face. The retaining assembly 104 can be bent to bring the adhesive on the first pad 114 and the second pad 116 into contact with the patient's cheek or face. The adhesive on the first pad 114 and the second pad 116 secures the pads 114 and 116 to the patient's cheek or face. After the system is secured to the patient, the face support 112 should be positioned between the patient's nose and mouth. After the first pad 114 and the second pad 116 are attached to the patient's cheek or face, the head strap 106 can be further adjusted as needed to ensure the best fit to the patient. The upper strap 220 and lower strap 222 can be adjusted by releasing the fastening portion 240 of each strap tab 238 or by tightening or loosening the upper strap 220 and / or lower strap 222 until they are in the desired position. The fastening portion 240 of each strap tab 238 is then secured to the corresponding upper strap 220 and lower strap 222, respectively, to fix the straps 220 and 222 in place. In some non-limiting embodiments, the retaining assembly 104 can be secured to the patient's face without attaching the head strap 106 to the retaining assembly 104. After the retaining assembly 104 is secured to the patient's face by the first and second pads 114 and 116, the head strap 106 can be secured to the retaining assembly 104 and then secured to the patient.

[0047] Next, referring to Figures 9-14, the tube holder 118 is shown in detail. As shown in Figure 9, the tube holder body 202 includes a shuttle 250, through which a shuttle chamber 252 passes. The shuttle 250 includes a first arm 254 and a second arm 256, both arms 254 and 256 partially enclose and define the shuttle chamber 252. As will be described in detail below, the shuttle 250 is configured to partially wrap around the track 140 of the bar 130 to secure the tube holder 118 to the holder 110. As shown in Figures 9 and 12, the tube holder body 202 also includes a latch 258 positioned forward of the shuttle 250. The latch 258 includes a first wing portion 260 connected to a first prong portion (projection portion) 262 and a second wing portion 264 connected to a second prong portion 266. The first and second prongs 262, 266 extend alongside the sides of the shuttle 250. In other words, a portion of the shuttle 250 is positioned between the first prong 262 and the second prongs 266. As will be described in detail below, the first and second prongs 262, 266 extend into a number of recesses 144 of the track 140, thereby securing the tube holder 118 in place.

[0048] Continuing to refer to Figures 9 and 12, a fixing flange 270 is provided extending from the tube holder body 202. The fixing flange 270 is equipped with a fixing rib 272 and is positioned above the passage 274. The fixing flange 270 is configured to interact with the nose portion 276 of the tube holder body 202. Specifically, the nose portion 276 of the tube holder body 202 is equipped with a projection 278 configured to fix the free end 280 of the fixing flange 270 in a downward position (see Figure 19). Figures 9 and 12 show the fixing flange 270 in an upward or open position. When the fixing flange 270 is in the downward position during use (Figure 19), the fixing flange 270 is configured to fix the tube strap 120 within the passage 274 between the tube holder body 202 and the fixing rib 272.

[0049] Referring to Figures 10 and 12, the bite block 204 extends rearward from the lower end 290 of the tube holder body 202, i.e., away from the nose portion 276. The bite block 204 is cylindrical and has side walls 292 that define the bite block passage 294. The bite block passage 294 penetrates the bite block 204. As shown in Figures 10 and 11, the side walls 292 of the bite block 204 only partially enclose the bite block passage 294, and the bite block 204 has a plurality of tusk-like portions 296. As shown in Figure 11, the first tusk-like portion 296a and the second tusk-like portion 296b of the plurality of tusk-like portions 296 extend from both ends of the bite block 204 toward the bite block passage 294. The first tusk-like portion 296a and the second tusk-like portion 296b form a side wall opening 298 of the bite block passage 294. The bite block 204 further comprises a third dentan portion 296c, which extends into the bite block passage 294 near the upper end of the bite block 204. The third dentan portion 296c is separated from the first dentan portions 296a and the second dentan portions 296b and extends along the entire bite block side wall 292. When in use, the bite block 204 is configured to extend between the teeth in the patient's mouth, and the tube 102 is configured to pass through the bite block passage 294. In some non-limiting examples, the bite block 204 can be molded integrally with the tube holder 118 to form a single, integral, indivisible part. Furthermore, in some non-limiting examples, the bite block 204 can be a separate component from the tube holder 118 and can be fixed to or attached to the tube holder 118. As described herein, the multiple dentan portions 296 described above are configured to fix the tube 102 into the bite block passage 294.

[0050] Referring to Figures 10, 12, and 14, multiple teeth 310 extend from the bottom surface 312 of the tube holder body 202. The multiple teeth 310 are conical in shape and are arranged in four rows C1, C2, C3, C4 and seven rows R1, R2, R3, R4, R5, R6, R7 (see Figure 14). The multiple teeth 310 include multiple first teeth 314 and multiple second teeth 316. The multiple first teeth 314 are larger than the multiple second teeth 316. Specifically, as shown in Figures 10 and 12, the multiple first teeth 314 extend from the bottom surface 312 of the tube holder body 202 at a greater distance than the multiple second teeth 316, and the diameter of the root portion of each of the multiple first teeth 314, i.e., the portion fixed to the bottom surface 312 of the tube holder body 202, is larger than the diameter of the root portion of each of the multiple second teeth 316. As shown in Figure 14, the multiple first teeth 314 are arranged on the outer portion of the bottom surface 312 of the tube holder body 202 (rows C1 and C4), and the multiple second teeth are arranged between the multiple first teeth 314 (rows C2 and C3). The multiple teeth 310 are arranged in pairs along rows R1, R2, R3, R4, R5, R6, and R7. In other words, of the multiple second teeth 316, two teeth in row R1 form a pair, and of the multiple first teeth 314, two teeth in row R2 form a pair, and so on. Each pair of the multiple first teeth 314 is positioned at a distance D1 from each other, and each pair of the multiple second teeth 316 is positioned at a distance D2 from each other. As shown in Figure 14, D1 is greater than D2. In some non-limiting examples, the distance D1 is approximately 1.0 mm to approximately 10.0 mm, or approximately 2.0 mm to approximately 6.0 mm, or approximately 3.0 mm to approximately 5.0 mm, or approximately 4.0 mm to approximately 5.0 mm, or approximately 4.0 mm, or at least approximately 3.0 mm, or at least approximately 4.0 mm. In some non-limiting cases, the distance D2 is approximately 0.5 mm to 4 mm, or approximately 1.0 mm to 2.0 mm, or approximately 1.0 mm, or approximately 1.2 mm, or at least approximately 1.0 mm.

[0051] Referring to Figure 14, each pair of multiple teeth 310 is offset from one another when extending along the anterior-posterior direction (see the direction of the arrows in columns C1, C2, C3, and C4). In other words, the pair in row R1, which includes two of the multiple second teeth 316 (one tooth in column C2 and one tooth in column C3) of the multiple teeth 310, is separated along the anterior-posterior direction from the pair in row R2, which includes two of the multiple first teeth 314 (one tooth in column C1 and one tooth in column C4) of the multiple teeth 310. As shown in Figure 14, all pairs of multiple teeth 310 are offset from or separated from other pairs along the anterior-posterior direction.

[0052] Next, referring to Figure 15, a cross-sectional view of the retaining assembly 104 is shown. As shown in Figure 15, the track 140 is located within the shuttle chamber 252 of the shuttle 250, and the tube holder 118 is fixed to the retainer 110. The first arm 254 of the shuttle 250 is located within the upper cavity 156 of the track, and the second arm 256 of the shuttle 250 is located within the lower cavity 158 of the track. As shown in Figures 1, 5, 6, 7 and 15, the first prong portion 262 of the latch 258 is located in one of the multiple recesses 144 on the surface of the track 140, and the second prong portion 266 of the latch 258 is located in one of the multiple recesses 144 on the surface of the track 140. Therefore, the combination of inserting the track 140 into the shuttle chamber 252 and engaging the prongs 262 and 266 with the multiple recesses 144 secures the tube holder 118 to the retainer 110. During use, the first and second wings 260 and 264 of the latch 258 act as hinges, and when the wings 260 and 264 move in the direction of arrow J (see Figure 7), the first prong 262 and the second prong 266 move outward and are released from the multiple recesses 144. When the prongs 262 and 266 are not secured to the multiple recesses 144, the tube holder 118 can slide along the track 140 between the track wall 150 and the track hinge 152. This allows the tube holder 118 to move and adjust relative to the retainer 110. As described here, the folding of the track hinge 152 allows the tube holder 118 to slide along the track 140 (see Figure 7). When placed on track 140, the contact portion 154 blocks the track hinge 152 from opening (see Figure 7), thereby preventing the shuttle 250 of the tube holder 118 from sliding off track 140.

[0053] Next, referring to Figure 16, the multiple teeth 310 are shown in more detail. As will be explained in detail below, the angles of the multiple teeth 310 are set differently depending on which row C1, C2, C3, C4 they belong to. The angles of the multiple teeth 310 are set so that when the tube 102 is fixed to the system 100, the axis of each tooth is substantially perpendicular to the tube 102 (see Figure 18). In this way, when the tube 102 is attached to the system 100, all of the multiple teeth 310 are in contact with the tube 102. This improves the grip between the system 100 and the tube 102.

[0054] Next, referring to Figure 17, isoangled top views of the retainer 110, face support 112, first pad 114, and second pad 116 are shown, and a track 140 with multiple recesses 144 is shown in detail. In some non-limiting examples, the number of recesses 144 on the track 140 may be more or less than those shown. Furthermore, in some non-limiting examples, the face support 112 may be integrated with the retainer 110 and not be a separate part.

[0055] Next, referring to Figure 18, an enlarged partial cross-sectional view of the tube holder 118 is shown, with the tube 102 indicated by a dashed line. As described above, each row C1, C2, C3, C4 of the multiple teeth 310 is set at a different angle from the other rows C1, C2, C3, C4. Specifically, each of the multiple first teeth 310 in row C1 has an axis A5, each of the multiple second teeth 316 in row C2 has an axis A6, each of the multiple second teeth 316 in row C3 has an axis A7, and each of the multiple first teeth 314 in row C4 has an axis A8. As shown in Figure 18, within each row R1, R2, R3, R4, R5, R6, R7, the axes A5, A6, A7, A8 form an angle with each other. In other words, in the same row R1, R2, R3, R4, R5, R6, R7 of multiple tooth portions 310, each axis A5, A6, A7, A8 is not parallel to the other axes A5, A6, A7, A8. As described here, each axis A5, A6, A7, A8 passes through the center of the root and the tip of each tooth portion 310 (see Figure 18).

[0056] Continuing to refer to Figure 18, when in use, the multiple teeth 310 are configured to contact the tube 102. As described above, the angles of the multiple teeth 310 are set so that axes A5, A6, A7, and A8 are substantially perpendicular to the outer surface 340 of the tube 102, and the multiple teeth 310 are positioned so that all of the multiple teeth 310 contact the tube 102 when the tube 102 is fixed to the system 100. This contact between the tube 102 and the multiple teeth 310 improves the grip between the system 100 and the tube 102.

[0057] Continuing to refer to Figure 18, axis A5 and the longitudinal center plane AC (which is perpendicular to the bottom surface 312 of the tube holder 118 and passes through the center of the bottom surface 312 of the tube holder 118, as shown in Figure 18) form angle B3, axis A8 and the longitudinal center plane AC form angle B4, axis A6 and the longitudinal center plane AC form angle B5, and axis A7 and the longitudinal center plane AC form angle B6. In some non-limiting examples, angles B3 and B4 are in the range of approximately 0° to approximately 60°, or approximately 5° to approximately 30°, or approximately 10° to approximately 25°, or approximately 15° to approximately 20°, or approximately 18°, or at least approximately 10°, at least approximately 15°, and at least approximately 18°, respectively. In some non-limiting examples, angles B5 and B6 are in the range of approximately 1° to approximately 60°, or approximately 3° to approximately 30°, or approximately 5° to approximately 15°, or approximately 5° to approximately 10°, or approximately 8°, or at least approximately 5°, or at least approximately 8°, respectively. The configuration of the multiple teeth 310 as described above allows each of the multiple teeth 310 to penetrate the tube 102 with approximately the same force and depth. Furthermore, by angling or tilting the centerlines / axes of the multiple teeth 310 as described above, the multiple teeth 310 become substantially perpendicular to the tube 102. Thus, the multiple teeth 310 provide maximum resistance in both rotational and lateral movements.

[0058] As described here, axes A5, A6, A7, and A8 correspond to multiple teeth 310 located in the first two rows R1 and R2 (see Figure 14). However, as shown in Figures 10, 11, 12, 14, and 18, the axes of the multiple teeth 310 in each column C1, C2, C3, and C4 are parallel. In other words, the multiple teeth 310 in each column C1, C2, C3, and C4 are identical, and are only separated from each other along the columns C1, C2, C3, and C4. For example, the first tooth 314 in column C1 and row R2 is identical to the first tooth 314 in column C1 and row R4, and is also identical to the first tooth 314 in column C1 and row R6. In some non-restrictive cases, multiple teeth 310 within each row C1, C2, C3, C4 can be different or non-identical across all rows C1, C2, C3, C4. In other words, each of the multiple teeth 310 within a single row is different from one another.

[0059] Continuing to refer to Figure 18, the axes A5, A6, A7, A8 of each of the multiple teeth 310 are not parallel to the longitudinal center plane AC. As shown in Figure 18, the axes A5, A6, A7, A8 of the multiple teeth 310 converge toward the longitudinal center plane AC below the base 312. In fact, the axes A5, A6, A7, A8 within a single row R1, R2, R3, R4, R5, R6, R7 converge toward each other below the base 312.

[0060] Continuing to refer to Figure 18, the multiple first teeth 314 have a distance D3 between the bottom surface 312 of the tube holder body 202 and the tips of the multiple first teeth 314. The multiple second teeth 316 have a distance D4 between the bottom surface 312 of the tube holder body 202 and the tips of the multiple second teeth 316. As described above, distance D3 is greater than distance D4. In some non-limiting examples, distance D3 is in the range of approximately 0.5 mm to approximately 5 mm, or approximately 0.8 mm to approximately 3.0 mm, or approximately 1.0 mm to approximately 1.5 mm, or approximately 1.3 mm, or approximately 1.4 mm, or at least approximately 0.5 mm, or at least approximately 1.0 mm, or at least approximately 1.3 mm. In some non-limiting cases, distance D4 is in the range of approximately 0.1 mm to approximately 5 mm, or approximately 0.5 mm to approximately 3 mm, or approximately 0.8 mm to approximately 1.3 mm, or approximately 1.0 mm, or approximately 1.1 mm, or at least approximately 0.5 mm, or at least approximately 1.0 mm. In some non-limiting cases, distance D3 is approximately 10% to approximately 50% greater than distance D4, or distance D3 is approximately 28% greater than distance D4.

[0061] Referring here to Figure 19, the system 100 is shown attached to the tube 102. As shown in Figure 19, the tube strap 120 is positioned around the tube 102 and secured within the passage 274 and below the fixing flange 270. Referring to Figures 1, 9, 12, 15, and 19, the method of attaching the tube 102 to the tube holder 118 of the system 100 is described below. Specifically, once the system 100 is fixed to the patient, the user or medical professional can intubate the tube 102 into the patient and pass it through the bite block passage 294. The tube 102 can be inserted into the bite block passage 294 through the side wall opening 298 of the bite block 204. Once the tube 102 is inserted into the bite block passage 294, the tube 102 aligns with the tube holder 118 and the multiple teeth 310. Next, the user or medical professional can wrap the tube strap 120 around the tube 102 to secure the tube 102 to the tube holder 118. Before wrapping the tube strap 120 around the tube 102, the user or healthcare professional can remove the tube strap release tab 216 to expose the adhesive. The adhesive can then be used to secure the tube strap 120 to the tube 102 when wrapping it around the tube 102. The adhesive helps to secure the tube strap 120 to the endotracheal tube 102. After being wrapped around the tube 102, the tube strap 120 will be positioned above the passage 274 and below the fixing flange 270. Once the tube strap 120 is positioned below the fixing flange 270, the user or healthcare professional can lower the fixing flange 270 to a downward position and clamp it. In this downward position, the projection 278 pushes a portion of the tube strap 120 into the passage 274, locking the tube strap 120 in place. To lower and fix the fixing flange 270 in a downward position, the user or medical professional can urge away the nose portion 276 of the tube holder 118 from the tube strap 120, thereby retracting the projection 278 and making the fixing flange 270 rotatable to a downward position.After the fixed flange 270 is in the downward position, the user or medical professional can release their hand from the nose portion 276 of the tube holder 118, and the projection 278 will lock the free end 280 of the fixed flange 270 in the downward position.

[0062] Referring to Figures 18 and 19, when the tube strap 120 secures the tube 102 to the tube holder 118, the tube 102 contacts and is secured to the multiple teeth 310. As described above, the angle of the multiple teeth 310 allows the tube 102 to be secured to the tube holder 118 more effectively. As stated here, if the system 100 is not provided with a bite block 2004, after the system 100 is placed on the patient and the tube 102 is placed in the user, the user or healthcare worker can immediately begin wrapping the tube strap 120 around the tube 102, i.e., the step of placing the tube 102 in the bite block 204 can be omitted. In some non-limiting examples, the tube 102 can be intubated into the patient before the system 100 is secured to the patient.

[0063] After the tube 102 is fixed to the tube holder 118, the tube holder 118 can be adjusted by moving it along the track 140 of the holder 110. Specifically, as described above, the first prongs 262 and 266 of the latch 258 can be moved by moving the wings 260 and 264 to remove them from the recess 144 on the surface of the track 140. Once the wings 260 and 264 are clamped in the direction of arrow J (see Figure 7), the tube holder 118 can be slid along the track 140 until it reaches the appropriate position. Since the tube 102 is fixed to the tube holder 118, the tube 102 can slide along the track 140 together with the tube holder 118. Once the appropriate position is reached, the user or medical professional can release their hands from the wings 260, 264 to return the first prongs 262 and the second prongs 266 to the recesses 144 and snap them into place, thereby fixing the tube holder 118 in a stationary position on the track 140.

[0064] As described here, system 100 prevents the endotracheal tube from moving while reinforcing its fixation. System 100 also helps minimize pressure on the patient's upper lip and reduce the risk of skin irritation. Thus, system 100, with its four-point fixation by the head strap 106 and retaining assembly 104, can improve fixation, enhance comfort, and reduce the risk of unplanned extubation, pressure ulcers, and skin damage. Furthermore, system 100 does not obstruct the tube 102. Therefore, system 100 improves the fixation of the tube 102.

[0065] This disclosure describes one or more public, non-limiting examples, and many equivalents, alternatives, modifications, and improvements are possible and should be understood to be within the scope of the present invention, in addition to those expressly described.

[0066] This disclosure should be understood as not being limited to its application to the configuration details and arrangement of components described in the appended specification or shown in the accompanying drawings. This disclosure may include other non-limiting examples and may be implemented or performed in various forms. Furthermore, the wording and terminology used in this application are for illustrative purposes only and should not be considered as limiting the invention. The words “include,” “equip,” or “have” and their variations in this specification are intended to include what is described as its object, as well as its equivalents and others. Unless otherwise specified or limited, the terms “attachment,” “connection,” “support,” and “linking,” and their variations, are used in a broad sense and include both direct and indirect attachment, connection, support, and linking. Furthermore, “connection” and “linking” are not limited to physical or mechanical connection or linking.

[0067] In this application, unless otherwise specified or defined, descriptions of specific directions are merely illustrative in relation to non-limiting specific examples or related explanations. For example, descriptions of "up," "front," and "back" configurations are generally intended to be merely descriptions of the direction of the configuration relative to the reference system of the specific example or explanation. Correspondingly, for example, the "upper" configuration may be positioned below the "lower" configuration in some arrangements or non-limiting examples. Furthermore, descriptions of specific rotations or other movements (e.g., counterclockwise rotation) are generally intended to be merely descriptions of the movement relative to the reference system of the specific example of the explanation.

[0068] Specific operations of the methods disclosed herein, or systems that perform those operations, may be briefly shown in the drawings or otherwise described. Unless otherwise specified or limited, the depiction in the drawings of specific operations in a particular spatial order does not necessarily require that such operations be performed in a specific order corresponding to that particular spatial order. Accordingly, specific operations shown in the drawings or otherwise disclosed may be performed in an order different from the order explicitly shown or described, as appropriate for certain non-limiting examples of the disclosure. Furthermore, in some non-limiting examples, specific operations may be performed in parallel, including by dedicated parallel processing units or separate computers interacting as part of a larger system.

[0069] In some embodiments, the equipment or system disclosed herein may be used or installed in a manner that embodies aspects of the disclosure herein. Accordingly, descriptions of specific configurations, capabilities, or intended purposes of equipment or systems herein are generally intended to essentially include disclosures of how such configurations are used for such intended purposes, how such capabilities are embodied, and how disclosed (or otherwise known) components are introduced to support such purposes or capabilities. Similarly, descriptions herein of methods of manufacturing or using equipment or systems, including the introduction of such equipment or systems, are also intended to essentially include, unless otherwise stated or limited, disclosures of configurations in which such equipment or systems are used and capabilities embodied, as non-limiting examples of the disclosure herein.

[0070] Unless otherwise defined or limited, the ordinal numbers used in this application are, for convenience of description, generally used to indicate the order in which specific components are described in the relevant sections of the disclosure. In this regard, for example, designations such as "First," "Second," etc., generally only indicate the order in which the components appear for illustrative purposes and do not indicate or require any specific spatial arrangement, functional or structural order, or priority.

[0071] In this application, unless otherwise defined or limited, terms relating to direction are used for the convenience of description to illustrate specific figures or examples. For example, descriptions of downward direction (or other directions) or upper position (or other positions) are used to describe specific examples or aspects of specific figures, but it is not necessarily the case that the same direction or geometric configuration is required for all installations or configurations.

[0072] This description is provided to enable a person skilled in the art to produce or use non-limiting examples of the disclosure. A person skilled in the art can easily derive various improvements to the illustrated examples, and their general principles can be applied to other cases and uses without departing from the principles disclosed herein. Therefore, the non-limiting examples of the disclosure are not intended to be limited to those shown in the figures, but should be considered to have the broadest scope consistent with the principles and configurations disclosed in the specification and claims. The accompanying detailed description should be read with reference to the drawings, where similar elements are denoted by the same reference numerals in different figures. The drawings are not necessarily to scale and illustrate selected examples, and are not intended to limit the scope of the disclosure. A person skilled in the art will recognize that numerous useful alternative embodiments exist for the examples presented herein and fall within the scope of the disclosure.

[0073] Furthermore, in this application, unless otherwise specified or defined, "or" and "or" mean a non-restrictive enumeration of configurations or operations that can exist in any various combinations, rather than a restrictive enumeration of configurations that can only exist as alternatives to each other. For example, when written as "A, B, or C," this means the following options: A, B, C, A and B, A and C, B and C, A, B, and C. Furthermore, the terms "or" and "or else" in this application are intended to mean exclusive alternatives only when preceded by an exclusive term, such as "either," "one of," "only one of," or "exactly one of." Moreover, when preceded by "one or more" (and variations thereof) and containing "or" or "or else" to distinguish between the listed elements, this means one or more choices from any or all of the listed elements. For example, both "one or more of A, B, or C" and "at least one of A, B, or C" mean the following choices: One or more A's, One or more B's, One or more Cs, One or more A's and one or more B's, One or more B and one or more C, One or more A's and one or more C's, Each of elements A, B, and C must be present, either one or more. Similarly, when an enumeration includes "or" or "or" to distinguish between the listed elements, it means that there are multiple options among any or all of the listed elements. For example, the statement "A, B, or C" means the following options: A and B, B and C, A and C, A, B, and C. In general, in this application, the terms "or" and "or else" mean exclusive alternatives only when preceded by an exclusive term, such as "either," "one of," "only one of," or "exactly one of."

[0074] Furthermore, in this application, numerical descriptions accompanied by terms such as "about" or "approximately" ("about," "approximately," etc.) mean a range of variation of ±5% or less from the given numerical value (e.g., ±3%, ±1%, etc.), unless otherwise specified or limited, provided that this range includes boundary values. Similarly, in this application, the phrase "substantially equal" means a range of variation of ±30% or less from a given numerical value, including boundary values ​​(e.g., ±20%, ±10%, ±5%). Where specified, "substantially" may particularly mean variation in one numerical direction relative to a given numerical value. For example, "substantially below" (or similar descriptions) a given numerical value means a value that is 30% or more smaller than that value, and "substantially above" (or similar descriptions) a given numerical value means a value that is 30% or more larger than that value.

[0075] Furthermore, in this application, "integral" and its derivatives (e.g., "integrally") refer to an element manufactured as a single piece without using fasteners or adhesives to secure multiple separate parts to each other. For example, an element punched out, cast, or otherwise formed as a single piece using a single sheet of metal or a single mold without using rivets, screws, or adhesives to connect separately formed parts is an integral part (and a part formed integrally). In contrast, a single part formed by connecting multiple parts that were initially formed separately is not an integral part (nor is it a part formed integrally).
