Description

Technical Field

[0001] This utility model relates to the field of endotracheal tube fixation technology, specifically to an endotracheal tube fixator. Background Technology

[0002] Endotracheal intubation is a method of inserting a specially designed endotracheal tube through the mouth or nose and through the glottis into the trachea or bronchus. It provides optimal conditions for airway patency, ventilation and oxygen supply, and airway suction, and is an important measure for rescuing patients with respiratory dysfunction.

[0003] In a prior art endotracheal intubation fixation device disclosed in CN116510146A, the clamp for fixing the endotracheal tube is designed to slide on the fixation device to adapt to different patients' anatomical structures and clinical needs. However, these designs share a common drawback: after the clamp slides to the desired position, there is a lack of an effective stopping mechanism to ensure its position is fixed. This may lead to the clamp shifting during clinical use due to patient movement or other external forces, thereby affecting the stability and safety of endotracheal intubation. Summary of the Invention

[0004] This invention proposes a convenient sliding positioning endotracheal tube fixation device, which solves the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows:

[0006] An endotracheal tube fixation device includes a clamp, an endotracheal tube, and a connecting mechanism connecting the two. The clamp is connected to fixation members at both ends, and the connecting mechanism includes guide members that are slidably disposed on the fixation members.

[0007] The fastener has multiple openings, and the guide has a plug-in structure that engages with the openings.

[0008] Furthermore, the inner side of the guide member has guide ribs, which are slidably adapted to the guide groove provided in the fixing member.

[0009] Furthermore, the connecting mechanism further includes a connector, and a retainer connected to the connector is fitted over the outside of the air tube.

[0010] Furthermore, the connector has a fixed plate on the side away from the ferrule, and a movable plate is hinged to the fixed plate. The movable plate flips to clamp the limiting band surrounding the fixed plate and the air tube.

[0011] Furthermore, locking blocks are provided at the edges of both sides of the fixed plate, and the two sides of the moving plate are respectively engaged with the locking blocks on both sides.

[0012] Furthermore, multiple ribs are provided on the adjacent sides of both the fixed plate and the moving plate.

[0013] The beneficial effects of the technical solution provided in this application are as follows:

[0014] This endotracheal tube fixator provides a mechanical locking mechanism through multiple openings on the fixator and engaging inserts on the guide. This ensures the endotracheal tube is stably fixed after being adjusted to the appropriate position, preventing displacement due to patient movement.

Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Reference Figure 1-2 A endotracheal tube fixation device includes a clamp 100, an endotracheal tube 300, and a connecting mechanism 200 connecting the two. The clamp 100 is connected to two fixing members 110 at both ends. The connecting mechanism 200 includes a guide member 210 slidably disposed on the fixing member 110. The fixing member 110 has multiple opening structures 111, and the guide member 210 is provided with a plug-in structure 211, wherein the plug-in structure 211 engages with the opening structure 111.

[0021] The clamp 100 is used to clamp the patient's head, and its two ends are connected to the fixation members 110. The clamp's design allows the fixator to adapt to different patient head sizes, ensuring that the fixator can be securely fixed to the patient's head. The fixation members 110 connect the two ends of the clamp 100, are strip-shaped and flexible, and can bend, allowing the fixation member to better conform to the shape of the patient's head and provide stable support. The flexibility of the fixation members 110 allows them to be adjusted according to the specific shape of the patient's head, improving the fixator's adaptability and patient comfort.

[0022] The connecting mechanism 200 connects the clamp 100 and the trachea 300. Its core component is the guide 210, which slides on the fixing member 110, allowing the trachea 300 to be adjusted in position relative to the fixing member 110. The guide 210 slides on the fixing member 110, allowing the trachea 300 to move along the length of the fixing member 110 to accommodate different patient needs. Multiple opening structures 111 on the fixing member 110 receive the insertion structure 211 on the guide 210, providing a mechanical locking mechanism to fix the position of the trachea 300. The insertion structure 211 on the guide 210 is a resilient insert that engages with the opening structure 111 on the fixing member 110, providing both fixation and stabilization. The resilient design of the insertion structure 211 allows it to adapt to different fixation force requirements while providing the necessary elastic deformation during engagement to ensure secure fixation. The guide 210 has hand-held blocks on both sides of the plug-in structure 211, which provides medical staff with better grip points, making it easier for them to operate the guide 210 to position and fix the trachea 300.

[0023] In some embodiments, the guide member 210 has a guide rib 212 on its inner side, and the guide rib 212 is slidably adapted to the guide groove 112 provided in the fixing member 110.

[0024] The guide rib 212 on the inner side of the guide member 210 is a key structure. It matches the guide groove 112 in the fixing member 110, ensuring that the guide member 210 slides along a predetermined path, thus improving the guiding and stability of the sliding. The guide groove 112 in the fixing member 110 cooperates with the guide rib 212 to provide a sliding channel, allowing the guide member 210 to move smoothly along the length of the fixing member 110.

[0025] The cooperation between the guide rib 212 and the guide groove 112 ensures that the guide member 210 does not deviate from the predetermined path during sliding, thus guaranteeing the accurate positioning of the trachea 300. This cooperation also helps reduce the friction of the guide member 210 when sliding on the fixation member 110, allowing medical staff to more easily adjust the position of the trachea 300. The cooperation between the guide rib 212 and the guide groove 112, combined with the flexibility of the fixation member 110, allows the entire fixation device to better conform to the contour of the patient's head, improving the fixation effect and patient comfort.

[0026] In some embodiments, the connecting mechanism 200 further includes a connector 220, and the outside of the air tube 300 is fitted with a retainer 310 connected to the connector 220.

[0027] The connector 220 is a component of the connecting mechanism 200 and is a block-shaped part. It is connected to the retaining sleeve 310 on the outside of the trachea 300, serving to connect and fix the trachea 300. The retaining sleeve 310 is fitted on the outside of the trachea 300 and connected to the connector 220. It is a ring or semi-ring structure used to fix the trachea 300 and allow it to slide along the fixing member 110.

[0028] The cooperation of connector 220 and ferrule 310 provides a stable connection between the endotracheal tube 300 and the other parts of the fixator, ensuring that the endotracheal tube 300 will not shift under external force. The design of ferrule 310 allows the endotracheal tube 300 to slide within a certain range to accommodate the needs of different patients while maintaining the stability of the endotracheal tube. The connection between connector 220 and ferrule 310 may include a slotted engagement, screw fastening, or other mechanical locking mechanisms to ensure the stable fixation of the endotracheal tube 300 on the fixator. The design of connector 220 needs to cooperate with the sliding mechanism of guide 210 to ensure that the endotracheal tube 300 can slide smoothly on fixator 110 while maintaining a stable connection with connection mechanism 200.

[0029] In some embodiments, the connector 220 has a fixed plate 221 on the side away from the sleeve 310, and a movable plate 222 is hinged to the fixed plate 221. The movable plate 222 is flipped to clamp the limiting band 224 surrounding the fixed plate 221 and the air tube 300.

[0030] The fixed plate 221 is a component of the connector 220 and is located on the side away from the ferrule 310. The fixed plate 221 has a fixed shape and size for supporting and positioning the subsequent components. The movable plate 222 is connected to the fixed plate 221 via a hinge structure, meaning that the movable plate 222 can rotate or flip about the hinge point. The movable plate 222 is designed to clamp the limiting band 224 when needed. The limiting band 224 wraps around the fixed plate 221 and the air tube 300 and is designed to provide an adjustable anchor point to limit the range of movement of the air tube 300.

[0031] The fixed plate 221 provides a stable platform, allowing the movable plate 222 to be reliably hinged and flipped when needed. The flipping function of the movable plate 222 effectively clamps the limiting band 224, thus fixing the position of the air tube 300 and preventing it from moving unnecessarily. The design of the fixed plate 221 and the movable plate 222 works in conjunction with the function of the connector 220 to ensure a stable connection between the air tube 300 and the retainer. The way the movable plate 222 clamps the limiting band 224, combined with the sliding locking mechanism of the guide 210 and the insert structure 211, provides precise adjustment and fixation of the air tube 300's position.

[0032] In some embodiments, locking blocks 223 are provided at the edges of both sides of the fixed plate 221, and the two sides of the moving plate 222 are respectively engaged with the locking blocks 223.

[0033] The locking blocks 223 are located on both sides of the fixed plate 221 and serve to engage with the movable plate 222. They are key components for fixing and locking the movable plate 222. The movable plate 222 can be rotated around the hinge point. Its sides are designed with structures that match the locking blocks 223 so that they can engage with the locking blocks 223 when rotated to a specific position.

[0034] The locking block 223 provides a physical locking mechanism. When the movable plate 222 is flipped to the appropriate position, the locking block 223 engages with the movable plate 222, thereby fixing the position of the movable plate 222 and preventing it from accidentally opening or shifting. This design allows medical personnel to reliably lock the current setting after adjusting the endotracheal tube fixator, ensuring stability and safety during patient use. The engaging design of the locking block 223 and the movable plate 222 ensures that the movable plate 222 can be stably held in the desired position after being flipped, providing a simple and effective locking method. The fixed plate 221 acts as a support for the locking block 223, ensuring the stability and durability of the locking block 223, and also providing a reliable connection point for the movable plate 222. The combined use of the locking block 223 and the movable plate 222, along with the clamping function of the limiting band 224, jointly ensures the fixation and stability of the endotracheal tube 300. This locking mechanism, in conjunction with the sliding locking mechanism of the guide 210 and the plug structure 211, provides flexibility in the use of the endotracheal tube fixator and stability after locking.

[0035] In some embodiments, the fixed plate 221 and the moving plate 222 are provided with multiple protruding ribs 225 on their adjacent sides.

[0036] Ribs 225 are multiple raised structures provided on the adjacent sides of the fixed plate 221 and the moving plate 222. They function when the moving plate 222 is pressed against the limiting band 224. Ribs 225 increase the frictional force when the fixed plate 221 and the moving plate 222 contact the limiting band 224, thereby improving the stability and reliability of clamping. The design of ribs 225 helps to provide a more uniform pressure distribution when the moving plate 222 clamps the limiting band 224, reducing local stress concentration and improving the overall structural durability.

[0037] The rib 225, in conjunction with the moving plate 222 and the fixed plate 221, improves the clamping effect when holding the limiting band 224, ensuring the stable fixation of the air tube 300. When the moving plate 222 flips and presses against the limiting band 224, the protruding part of the rib 225 helps to grip the limiting band 224, preventing it from sliding or shifting. The design of the rib 225 needs to cooperate with the engaging connection mechanism of the locking block 223 and the moving plate 222 to ensure that the rib 225 can function effectively in the locked state, increasing stability. The combination of the rib 225 with the sliding mechanism of the guide 210 and the engaging mechanism of the plug-in structure 211 provides stability and flexibility for the air tube 300 during adjustment and fixation.
