[0049] like Figure 1 As shown, this embodiment provides a tracheal tube holder, which is used to fix the tube 10 inserted into the patient's oral cavity during the process of tracheal intubation 10, to prevent the tube 10 from moving up and down and to facilitate disassembly. For the convenience of structural description, the left and right directions of the patient's body are used as the left and right directions of the structural description, and the direction of entering and exiting the patient's oral cavity is the up and down direction of the structural description, wherein one side of the oral cavity outlet is the top, and one side of the oral cavity inlet is the bottom, and the direction away from and toward the head is the front and back direction of the structural description, so in the above direction description, the patient's chin is located in front of the oral cavity.

[0050] like Figure 1 , Figure 2 As shown, the endotracheal tube holder of this embodiment mainly includes: a strap 100, a sliding connector 200, an anti-bite member 300 and a locking member 400. The strap 100 can be worn on the patient's head, and by being tied to the patient's head, the endotracheal tube holder can be retained in the patient's oral cavity. The strap 100 can adopt a belt structure with Velcro or an elastic ring structure, and a guide member 110 extending in the left and right directions is provided on the strap 100. The strap 100 is worn on the patient's head so that the guide member 110 is located between the nostrils and the oral cavity. The guide member 110 extends a predetermined length in the left and right directions, and the sliding connector 200 is slidably provided on the guide member 110 in the left and right directions; thereby, the left and right position of the sliding connector 200 on the guide member 110 is adjustable; the sliding connector 200 extends in the front-to-back direction, one end of which can be slidably connected to the guide member 110, and the other end is located above the patient's oral cavity. As shown in FIG. Figure 1 , Figure 3As shown, the bite-proof member 300 is detachably connected to the sliding connection member 200 and is used to be inserted into the patient's oral cavity. The bite-proof member 300 is provided with a first opening lock slot 311, and the opening of the first opening lock slot 311 can face one side in the left and right directions. The bite-proof member 300 is connected to the sliding connection member 200, so that the sliding connection member 200 can drive the bite-proof member 300 to move left and right, and the bite-proof member 300 is used to be inserted into the patient's oral cavity, which can protect the fixed cannula 10 and prevent the cannula 10 from being bitten by the patient's teeth. Figure 1 , Figure 3 , Figure 4 As shown, the locking member 400 and the anti-bite member 300 can be separated in the left and right directions, and the locking member 400 is provided with a second opening lock groove 421, and the opening of the second opening lock groove 421 faces the other side of the left and right directions; the locking member 400 is connected with the anti-bite member 300, so that the first opening lock groove 311 and the second opening lock groove 421 form an installation cavity 401, and the installation cavity 401 is used to fix the cannula 10 inserted into the patient's mouth.

[0051] like Figure 1 , Figure 2 As shown, a tracheal tube fixer of this embodiment is fixed to the patient's head by a strap 100, so that the sliding connector 200 can be slidably arranged on the guide member 110 of the strap 100 in the left-right direction, so that the sliding connector 200 can move in the left-right direction with the anti-bite member 300 and the locking member 400. The anti-bite member 300 and the locking member 400 are detachable and cooperate to form a mounting cavity 401 for fixing the cannula 10. When the cannula 10 is fixed, the sliding connector 200 is fixed on the guide member 110 and will not move in the left-right direction; the anti-bite member 300 and the locking member 400 lock the cannula 10 so that the cannula 10 will not move in the up-down direction, so that the cannula 10 can be stably fixed and the cannula 10 will not fall out of the patient's mouth. When the patient's oral cavity needs to be cleaned, the sliding connector 200 can be slid in the left and right directions, and the anti-bite piece 300 and the locking piece 400 can be moved in the left and right directions to move the intubation tube 10 to one side of the patient's oral cavity (the trachea does not move in the inside and outside directions of the oral cavity), leaving the other side of the patient's oral cavity free, so that there is space to clean the patient's oral cavity, making the cleaning process more convenient. When the anti-bite piece 300 and the locking piece 400 need to be cleaned, the anti-bite piece 300 and the locking piece 400 can be disassembled for easy replacement or cleaning. This ensures that the medical care process of the tracheal intubation 10 patient is more clean and hygienic.

[0052] like Figure 1 , Figure 2 , Figure 3As shown, further, the guide member 110 includes an arc plate 111, which can be made of a hard rubber plate and extends in the left and right directions. The strap member 100 is connected to both ends of the arc plate 111 in the left and right directions. When the strap member 100 is worn in the patient's oral position, the arc plate 111 can be stably attached to the upper part of the upper lip to play a fixing role. The arc plate 111 is provided with a guide rail 112, which can be a dovetail guide rail, which is extended in the left and right directions and arranged on the upper surface of the arc plate 111.

[0053] like Figure 1 , Figure 3 , Figure 4 As shown, the sliding connection member 200 specifically includes: a movable connection part 210, an extension support plate 220 and a support seat 230. The movable connection part 210 can be slidably arranged on the guide rail 112; a dovetail groove 211 is provided on the movable connection part 210, and the dovetail groove 211 is sleeved on the dovetail guide rail so that the sliding connection member 200 can slide left and right along the guide rail 112. A locking screw 212 is screwed on the movable connection part 210, and the movable connection part 210 can be fixed at a predetermined position in the left and right direction of the arc plate 111 by turning the locking screw 212, and the movable connection part 210 can slide left and right on the arc plate 111 by loosening the locking screw 212. The extension support plate 220 is connected to the movable connection part 210, and the extension support plate 220 extends a predetermined length in the front-to-back direction. The support seat 230 is connected to the extension support plate 220; the extension support plate 220 also adopts a hard rubber plate, so that the extension support plate 220 is not easy to deform in the up-down direction, and the extension support plate 220 extends to the upper part of the patient's mouth, so that the support seat 230 is fixed above the mouth. The anti-bite piece 300 is detachably connected to the support seat 230, and the anti-bite piece 300 extends downward and is used to be inserted into the patient's mouth to below the teeth. The anti-bite piece 300 can be set on the left side of the support seat 230, and the opening of the first opening lock groove 311 faces the left side, so that the outer walls of the front and rear sides of the anti-bite piece 300 protect the cannula 10 in the installation cavity 401. When the patient's teeth bite, the front and rear teeth can only bite the outer wall of the anti-bite piece 300, and will not bite the cannula 10, so that the cannula 10 is effectively protected. When the cannula 10 is inserted into the mounting cavity 401, it is fixed by the cooperation of the anti-bite piece 300 and the locking piece 400. The anti-bite piece 300 and the locking piece 400 are supported and limited in the up and down directions by the support seat 230, so that the cannula 10 is not easy to move in the up and down directions.

[0054] like Figure 1 , Figure 3 , Figure 4As shown, further, a base 240 is provided on the sliding connection member 200. Specifically, the base 240 is fixedly provided on the support seat 230. The locking member 400 includes: a locking portion 410 and a locking plate 420; the locking portion 410 is detachably provided in the base 240, the locking plate 420 is provided on the locking portion 410, and the second opening lock groove 421 is provided on the locking plate 420. In the specific structure, the locking portion 410 is U-shaped when in use, at least one end of the locking portion 410 can be inserted into the base 240, the locking plate 420 is arc-shaped and can be located on the inner side wall of the middle position of the U-shaped locking portion 410, and the locking plate 420 and the locking portion 410 surround the second opening lock groove 421. By detachably connecting the locking portion 410 to the base platform 240, the first open locking groove 311 and the second open locking groove 421 can be engaged or separated, thereby realizing the disassembly of the locking member 400 and the anti-bite member 300. After being separated from the cannula 10, the cannula 10 can still be inserted in the patient's mouth without moving, so that the locking member 400 and the anti-bite member 300 can be separated and removed from the left and right sides for cleaning and replacement.

[0055] In another structure, the seat platform 240 can also be set on the anti-bite component 300, and can also be connected to the locking component 400 to achieve the technical effect.

[0056] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, further, the lock part 410 in this embodiment can adopt a lock belt, and a latch tooth 411 is provided on the inner wall of the lock belt. A lock hole 241 is provided on the base 240, and a one-way latching part 250 is provided in the lock hole 241. The one-way latching part 250 is used to cooperate with the latch tooth 411 so that the lock part 410 can be inserted into the lock hole 241 in one direction. In the specific structure, the base 240 is provided with two lock holes 241 on the two bases 240, respectively, and the two ends of the lock part 410 are respectively inserted into the lock hole 241. Due to the effect of the one-way latching part 250, when the lock part 410 is inserted from the left side to the right side, it can be smoothly inserted into the lock hole 241; and when the lock part 410 is pulled out from the right side to the left side, the one-way latching part 250 locks the latch tooth 411, so that the lock part 410 cannot be directly pulled out, thereby achieving a locking effect. When it is necessary to pull out, the one-way clamping portion 250 is unlocked, so that the locking portion 410 is withdrawn from the clamping base 240 to achieve a detachable connection.

[0057] like Figure 1 , Figure 3 , Figure 5As shown, further, the one-way clamping portion 250 of this embodiment specifically includes: an elastic plate 251, a clamping block 254 and a release pressure plate 257. The elastic plate 251 is arranged on the inner wall of the lock hole 241 and has a certain elasticity. Specifically, one end of the elastic plate 251 connected to the first inner wall of the lock hole 241 can adopt an arc-shaped end 252, and the arc-shaped end 252 can increase the elasticity of the elastic plate 251. The other end of the elastic plate 251 extends obliquely toward the second inner wall of the lock hole 241. The first inner wall and the second inner wall are two opposite inner walls of the lock hole 241. The clamping block 254 is arranged on the other end of the elastic plate 251, and the clamping block 254 and the second inner wall of the lock hole 241 are spaced apart to form an extrusion channel. When the locking part 410 is inserted, the locking block 254 is squeezed so that the locking block 254 gives way under the elastic force of the elastic plate 251, thereby increasing the squeezing channel and allowing the locking part 410 to be smoothly inserted. When it is to be withdrawn, the locking block 254 is squeezed toward the locking part 410 under the elastic force of the elastic plate 251, so that the locking block 254 abuts against the latch tooth 411, preventing the locking part 410 from being withdrawn. The release pressure plate 257 is arranged on the elastic plate 251 and protrudes from the locking hole 241. The locking block 254 is moved away from the locking portion 410 by squeezing the release pressure plate 257. In order to allow the locking portion 410 to be smoothly withdrawn, the release pressure plate 257 located on the outside of the locking hole 241 is pressed to deform the elastic plate 251 and disengage the locking block 254 from the locking tooth 411. At this time, the squeezing channel becomes larger, so that the locking portion 410 can be smoothly withdrawn from the locking hole 241, thereby realizing the separation of the locking member 400 and the base 240.

[0058] like Figure 3 , Figure 5As shown, in order to achieve the above functions, in a matching structure between the latch 411 and the latch block 254, the latch 411 has a first insertion surface 412 on the side facing the insertion direction, and the first insertion surface 412 is inclined; the side facing the withdrawal direction has a first stop surface 413, and the first stop surface 413 can be a vertical surface. Correspondingly, the latch block 254 has a second stop surface 255 on the side facing the insertion direction, and the latch block 254 has a second insertion surface 256 on the side facing the withdrawal direction, and the second insertion surface 256 is inclined. When the latch 411 on the lock part 410 is inserted, the first insertion surface 412 squeezes the second insertion surface 256. Since the first insertion surface 412 is inclined, the latch block 254 can be squeezed open smoothly during the insertion process. After the multiple latches 411 squeeze the latch block 254 in sequence, the locking plate 420 of the lock part 400 gradually approaches the anti-bite part 300 and presses the cannula 10. After the latch 411 passes through the locking block 254, the first stop surface 413 of the latch 411 reaches the second stop surface 255 of the locking block 254, and both are vertical surfaces, so that the second stop surface 255 on the locking block 254 blocks the latch 411, thereby preventing the latch 411 from moving in the withdrawal direction, thereby locking the cannula 10.

[0059] One end of the release plate 257 is connected to the side of the elastic plate 251 away from the second inner wall, and the other end extends obliquely toward the other card seat 240. In this way, the release plates 257 on both sides can be pressed by fingers to drive the elastic plate 251 to deform and make the positioning block 254 away from the second inner wall.

[0060] like Figure 5 As shown, in another structure of the release plate 257, a through slot 242 is provided on the first inner wall of the base 240, and the release plate 257 passes through the through slot 242. An elastic support plate 258 is provided on the outer wall of the release plate 257. The elastic support plate 258 is located in the lock hole 241 and forms a predetermined angle with the release plate 257. The elastic support plate 258 abuts against one or both sides of the through slot 242 and abuts against the first inner wall. Through the elastic support of the elastic support plate 258, the release plate 257 has a certain elastic force toward the second inner wall, so that a more stable elastic force support can be provided to the clamping block 254 on the elastic plate 251. When the release plates 257 on both sides can be pressed by fingers, the elastic support plate 258 is deformed, so that the end of the elastic plate 251 facing the second inner wall is deformed more, while the end facing the first inner wall is deformed less, so that the end of the elastic support plate 258 connected to the first inner wall is not easily broken during repeated withdrawal. The positioning block 254 is fixed to the end of the elastic plate 251 facing the second inner wall, so that when the deformation of this end is larger, the positioning block 254 can be made to give way.

[0061] like Figure 2 , Figure 3 , Figure 4 As shown, further, the bite-proof member 300 of this embodiment specifically includes: a locking portion 310, an anti-bite portion 330 and an inserting portion 320. The locking portion 310 is connected to the sliding connection member 200, and the first opening lock groove 311 is provided on the locking portion 310; the bite-proof portion 330 is provided on the locking portion 310 and is used to extend toward the patient's mouth, the bite-proof portion 330 protrudes toward the opening side of the first opening lock groove 311, and is provided with a U-shaped protection groove 332, and the U-shaped protection groove 332 is connected to the first opening lock groove 311. The inserting portion 320 is provided on the side of the locking portion 310 away from the first opening lock groove 311, and can be detachably inserted into the sliding connection member 200. Therefore, when the anti-bite component 300 is connected to the support seat 230 of the sliding connection component 200 through the plug-in portion 320, the locking portion 310 located above can cooperate with the locking portion 410 to fix the cannula 10. The anti-bite portion 330 is located below the locking portion 310 and extends downward to the bottom of the patient's teeth (tongue side). The cannula 10 is located in the U-shaped protective groove 332 to achieve a protective function.

[0062] like Figure 2 , Figure 3 , Figure 6 As shown, further, the anti-bite portion 330 in this embodiment includes an anti-bite support plate 331 protruding toward the opening direction of the first opening lock groove 311, and the anti-bite support plates 331 are respectively located on both sides of the U-shaped protection groove 332. Since the anti-bite support plates 331 on the front and rear sides are protruding, the patient's teeth are separated from the cannula 10 inside the U-shaped protection groove 332 on the front and rear sides.

[0063] like Figure 2 , Figure 4 , Figure 6As shown, further, an extrusion chamfer 333 is provided on the inner edge of the anti-bite support plate 331 on the side facing the locking portion 310, and the extrusion chamfer 333 is gradually inclined from top to bottom close to the center line of the U-shaped protection groove 332, so that the upward opening of the anti-bite support plate 331 is trumpet-shaped. A flexible extrusion edge 422 is provided on the side of the locking plate 420 facing the anti-bite portion 330, and the flexible extrusion edge 422 can be made of a silicone layer. The flexible extrusion edge 422 is compressed by the extrusion of the extrusion chamfer 333 to limit the downward movement of the cannula 10 accommodated in the installation cavity 401. When the locking portion 410 is inserted along the insertion direction, the locking plate 420 is moved closer to the locking portion 310, and the flexible extrusion edge 422 below the locking plate 420 gradually enters the extrusion chamfer 333. The flexible extrusion edge 422 is extruded by the extrusion chamfer 333, so that the flexible extrusion edge 422 is deformed and shrinks toward the inside of the inner mounting cavity 401, thereby squeezing and fixing the insert tube 10 inside the mounting cavity 401. When the insert tube 10 tends to move downward, due to the inclined action of the extrusion chamfer 333, the flexible extrusion edge 422 shrinks tighter and tighter downward, thereby preventing the insert tube 10 from moving downward.

[0064] like Figure 2 , Figure 3 , Figure 6 As shown, further, a negative Poisson's ratio support portion 423 is provided on the edge of the locking plate 420 away from the flexible extrusion edge 422, and the negative Poisson's ratio support portion 423 is used to limit the upward movement of the cannula 10 accommodated in the installation cavity 401. When the cannula 10 moves upward, the negative Poisson's ratio support portion 423 has the characteristic of expanding toward the inner side of the installation cavity 401, so when the cannula 10 is pulled upward, the negative Poisson's ratio support portion 423 is subjected to an upward pulling force, and the negative Poisson's ratio support portion 423 expands inwardly, thereby shrinking the upper opening of the installation cavity 401. After the shrinkage, the upper opening of the installation cavity 401 becomes smaller and tightly covers the cannula 10, so that the cannula 10 is not easy to slip out of the installation cavity 401 upward.

[0065] Furthermore, in this embodiment, a compression microstructure (not shown) is disposed inside the first open locking groove 311 and on the inner wall of the second open locking groove 421, and the compression microstructure is used to squeeze the cannula 10 located in the installation cavity 401. The compression microstructure can be a flexible protrusion and / or groove, and in the process of the locking portion 310 and the locking plate 420 compressing the cannula 10, these compression microstructures can effectively enhance the friction force of the tube wall of the cannula 10, and prevent the cannula 10 from loosening on the fixture.

[0066] like Figure 2 , Figure 4 , Figure 7As shown, further, the sliding connector 200 of this embodiment is provided with a plug-in assembly (not marked in the figure), which is disposed on the support seat 230 and is used to cooperate with the plug-in portion 320 for detachable connection.

[0067] like Figure 4 , Figure 7 As shown, the plug assembly specifically includes: a plug hole 231 and a pressing and clamping portion 260. The plug hole 231 is provided on the sliding connector 200, the pressing and clamping portion 260 is telescopically arranged in the plug hole 231, and the plug part 320 is inserted into the plug hole 231 and limited by the pressing and clamping portion 260.

[0068] like Figure 4 , Figure 7 As shown, in the specific structure, the plug hole 231 adopts a through hole. The plug part 320 includes an insert rod 321 and a cleaning ring 322 located at the lower end of the insert rod 321; the insert rod 321 is used to be inserted into the plug hole 231. During the insertion process, the cleaning ring 322 at the lower end contacts the inner wall of the plug hole 231, thereby scraping the inner wall of the plug hole 231 from top to bottom, so as to facilitate cleaning of impurities in the plug hole 231 and facilitate cleaning of the fixture.

[0069] like Figure 4 , Figure 7 As shown, a locking groove 323 is provided on the insertion rod 321. When the insertion rod 321 is inserted into the insertion hole 231, the pressing and clamping part 260 is clamped on the locking groove 323 for limiting the position. When the anti-bite component 300 is to be removed from the support seat 230, the pressing and clamping part 260 can be pressed to disengage the pressing and clamping part 260 from the locking groove 323 to release the limit.

[0070] like Figure 4 , Figure 7As shown, the pressing and clamping part 260 specifically includes: a lever 261, a clamping platform 262, a spring 263 and a pressing button 264. Pressing installation spaces 232 are respectively arranged on both sides of the plug hole 231 on the support seat 230. The pressing and mounting spaces 232 are connected with the plug hole 231 through the telescopic hole 233. The lever 261, the clamping platform 262 and the spring 263 are all arranged in the pressing and mounting spaces 232. The pressing button 264 penetrates the outer wall of the support seat 230 and extends to the pressing and mounting spaces 232. The lever 261 is hinged in the pressing and mounting spaces 232 through the hinge seat 265, and the lever 261 is divided into a first section and a second section by the hinge seat 265. The clamping platform 262 is fixedly arranged at the end of the first section and enters and exits the telescopic hole 233 through the rotation of the lever 261. The spring 263 is connected to the end of the second section and is used to pull it in a direction away from the plug hole 231. The push button 264 is movably connected to the second section of the lever 261 and is located between the spring 263 and the hinge seat 265. Therefore, when the insertion rod 321 is inserted downward into the insertion hole 231, the clamping platform 262 is retracted into the telescopic hole 233 under the downward pressure of the insertion rod 321, and the spring 263 is stretched to generate elastic force; when the locking groove 323 slides to the position of the clamping platform 262, the spring 263 returns to drive the lever 261 to rotate, and the clamping platform 262 is pushed out of the telescopic hole 233 and inserted into the locking groove 323, thereby locking the insertion rod 321. When unlocking is required, by pressing the push button 264, the push button 264 presses the lever 261 inward, and the lever 261 rotates to drive the clamping platform 262 to retract into the telescopic hole 233, thereby unlocking and smoothly pulling the insertion rod 321 out of the insertion hole 231. In this embodiment, the length of the first section is smaller than that of the second section; therefore, during the locking process, the card table 262 is inserted into the locking groove 323 only by the elastic force provided by the spring 263. According to the principle of the lever 261, the insertion rod 321 is not easily pulled out after being locked, and the locking effect is good.

[0071] In summary, the endotracheal tube holder provided by the present application can fix the tube so that the tube will not fall out of the patient's mouth. When the patient's mouth needs to be cleaned, the tube can be slid to one side of the patient's mouth so that the other side can be used to enter the tool and clean the patient's mouth. When the holder needs to be cleaned, the holder can be easily disassembled for replacement or cleaning. This makes the medical care process of patients with endotracheal tubes more convenient.
