Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an integrated fixation device for endotracheal tube and dental pad. Background Technology

[0002] In modern medicine, endotracheal intubation is a crucial procedure widely used in anesthesia, emergency care, and intensive care to establish an effective artificial airway and ensure the patient's respiratory function. During intubation, a bite block is essential to prevent unconscious biting down on the endotracheal tube, which could impair ventilation or even endanger the patient's life. Traditionally, the endotracheal tube and bite block are separate, requiring medical staff to manually position and secure them after intubation—a relatively complex and precise procedure. With continuous advancements and innovations in medical technology, the need to improve the efficiency of endotracheal intubation, reduce risks, and enhance patient comfort has become increasingly urgent. An integrated endotracheal tube and bite block fixation device has emerged to optimize the overall process and effectiveness of endotracheal intubation.

[0003] In existing technology, the endotracheal tube and bite block exist separately. During endotracheal intubation, the endotracheal tube is first inserted into the patient's trachea to a suitable position, and then the laryngoscope is removed. Afterwards, medical staff need to pick up the bite block separately, place it between the patient's teeth in a suitable position, and then use adhesive tape or other tools to fix the bite block and endotracheal tube to the patient's mouth. This fixation method relies on the adhesiveness of the tape to maintain the relative position of the bite block and endotracheal tube. The tape needs to be wrapped around the patient's face in an appropriate position and adhere tightly to the skin to ensure a secure fixation. During the fixation process, medical staff need to rely on experience and visual observation to judge whether the wrapping force and position of the tape are appropriate, while also being careful to avoid excessive pressure or irritation to the patient's skin, especially for patients who require endotracheal tube support for a long time. The reliability and stability of the tape fixation can be affected over time and with patient activity, and the adhesiveness of the tape can weaken due to factors such as oral secretions, increasing the risk of bite block displacement or endotracheal tube dislodgement.

[0004] The traditional method of separately fixing the endotracheal tube and bite block has significant drawbacks. Because separate procedures and fixation are required, this greatly increases the time needed to install the bite block, potentially delaying optimal treatment in critical emergency situations. Furthermore, during the period between laryngoscope removal and complete bite block fixation, patients are highly susceptible to trismus and biting the tube. This can rapidly lead to airway obstruction, potentially causing suffocation and posing a serious threat to the patient's life. Additionally, the traditional method suffers from poor fixation stability; adhesive tape fixation is easily affected by various factors, making it difficult to ensure the bite block and endotracheal tube remain in the ideal position, thus impacting the overall effectiveness and safety of the endotracheal intubation. Therefore, an integrated endotracheal tube and bite block fixation device is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an integrated fixation device for endotracheal tube and mouthguard, which aims to improve the problem that the existing technology cannot quickly and easily fix the mouthguard in the appropriate position.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated endotracheal tube and bite block fixation device includes an endotracheal tube, an occlusal component on the outer wall of the endotracheal tube, the occlusal component acting on the patient's bite to protect the endotracheal tube, and a fixation component on the outer wall of the occlusal component, the fixation component acting to fix the occlusal component.

[0008] The occlusal assembly includes a dental pad, which is slidably connected to the outer wall of the endotracheal tube. An occlusal portion is provided inside the dental pad, and a fixing ring is fixedly connected to the outer wall of the dental pad. A through surface is provided inside the fixing ring.

[0009] As a further description of the above technical solution:

[0010] The fixing component includes a fixing strap, which is disposed on the outside of the fixing ring;

[0011] As a further description of the above technical solution:

[0012] One end of the fixing strap is fixedly connected to a connecting surface, and the outer wall of the connecting surface is fixedly connected to the outer wall of the fixing ring.

[0013] As a further description of the above technical solution:

[0014] The inner wall of the connecting surface is attached to the outer wall of the endotracheal tube, and the fixing strap and the connecting surface form a wrap around the endotracheal tube.

[0015] As a further description of the above technical solution:

[0016] The inner wall of the fixing strap is fixedly connected with a hook and loop fastener, and the outer wall of the connecting surface is provided with a hook and loop fleece. The hook and loop fleece is adhered to the hook and loop fastener.

[0017] As a further description of the above technical solution:

[0018] A fixed column is fixedly connected inside the connecting surface, and a pin is rotatably connected to the outer wall of the fixed column;

[0019] As a further description of the above technical solution:

[0020] The fixing band has multiple slots inside, and the outer wall of the pin is slidably connected to the inside of the slots.

[0021] This utility model has the following beneficial effects:

[0022] In this invention, when the endotracheal tube is inserted to the appropriate position, after the laryngoscope is removed, the bite block can be directly pushed from the top of the device to the appropriate position. Then, the fixing strap on the bite block is used to tighten it to the outer wall of the endotracheal tube. After that, the pin is inserted into the corresponding slot to prevent the tube from becoming too narrow due to excessive tightness. Finally, the bite block is connected to the tube by the Velcro hook side and the felt side, which is convenient and quick, reduces the time for installing the bite block, and prevents the patient from biting the tube after the laryngoscope is removed.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 - Figure 3 An embodiment of this utility model provides: an integrated fixation device for endotracheal tube and bite block, including an endotracheal tube 1, an occlusal component provided on the outer wall of the endotracheal tube 1, the occlusal component acting on the patient's bite to protect the endotracheal tube 1, and a fixation component provided on the outer wall of the occlusal component, the fixation component acting to fix the occlusal component.

[0030] The occlusal component includes a dental pad 2, made of medical-grade rubber material with a certain degree of hardness and elasticity. This material can withstand the patient's biting pressure without causing excessive damage to the teeth and oral mucosa. The dental pad 2 is slidably connected to the outer wall of the endotracheal tube 1. An occlusal portion 5 is provided inside the dental pad 2, and the surface of the occlusal portion 5 has an uneven texture. This texture significantly increases the friction with the teeth, preventing slippage during biting, thus better fixing the position of the dental pad 2 and distributing the biting force. A fixing ring 6 is fixedly connected to the outer wall of the dental pad 2. The fixing ring 6 is made of rigid plastic material with sufficient strength to support subsequent fixation operations. The fixing ring 6 has a passage surface 7 inside. The fixation component includes a fixation strap 3, made of breathable, soft, and elastic medical-grade non-woven fabric material. This material can withstand the patient's biting pressure without causing excessive damage to the teeth and oral mucosa. It ensures a secure fixation while providing comfort for patients during prolonged wear, reducing pressure and friction on the skin. The fixation strap 3 is located on the outside of the fixation ring 6, with a connecting surface 9 fixedly connected to one end. The outer wall of the connecting surface 9 is fixedly connected to the outer wall of the fixation ring 6, and the inner wall of the connecting surface 9 is attached to the outer wall of the endotracheal tube 1. The fixation strap 3 and the connecting surface 9 form a wrap around the endotracheal tube 1. A Velcro hook surface 12 is fixedly connected to the inner wall of the fixation strap 3, and a Velcro fleece surface 11 is provided on the outer wall of the connecting surface 9. The Velcro fleece surface 11 is adhered to the Velcro hook surface 12. A fixing post 10 is fixedly connected inside the connecting surface 9. The fixing post 10 is made of stainless steel, which has good corrosion resistance and mechanical strength. A pin 8 is rotatably connected to the outer wall of the fixing post 10. Multiple slots 4 are opened inside the fixation strap 3, and the outer wall of the pin 8 is slidably connected inside the slots 4.

[0031] Specifically, after the endotracheal tube is accurately intubated to the appropriate position, the crucial step is to remove the laryngoscope. During this process, the fixing ring 6 plays a vital role. It provides a leverage point and guide path for pushing the bite block 2, allowing medical staff to smoothly and efficiently push the bite block 2 along the outer wall of the endotracheal tube 1 to the predetermined suitable position. Simultaneously, the smooth surface of the surface 7 reduces frictional resistance between the bite block 2 and the laryngoscope and endotracheal tube 1, facilitating the smooth removal of the laryngoscope and effectively reducing obstacles during the removal process. The bite block 2 is then fixed. First, the soft yet strong fixing band 3 is carefully wrapped around the outer wall of the endotracheal tube 1 and moderately tightened. Then, the pin 8 is precisely passed through the slot 4 to achieve initial accurate fixation, effectively preventing the bite block 2 from sliding due to excessive looseness or the internal diameter of the endotracheal tube 1 from narrowing due to excessive tightness, thus affecting ventilation. Finally, the secure and convenient adhesion between the hook side 12 and the loop side 11 further enhances the fixation effect, firmly fixing the bite block 2 to the outer wall of the endotracheal tube 1. This reduces the time required to install the bite block 2 and prevents the risk of the patient biting the tube after the laryngoscope is removed.

[0032] Working principle: After the trachea is intubated to the appropriate position, the laryngoscope needs to be removed. During removal, the bite block 2 can be pushed to the appropriate position by fixing the ring 6 to prevent the patient from biting the tube when the laryngoscope is removed by clenching their jaw. The through surface 7 facilitates the removal of the laryngoscope and reduces obstruction. Then, the fixing strap 3 is wrapped and tightened around the outer wall of the tracheal tube 1, and the pin 8 is passed through the inside of the slot 4 for accurate fixation to prevent slippage due to being too loose or narrowing of the tube due to being too tight. Finally, the hook side 12 is connected to the Velcro velvet side 11 to conveniently fix the bite block 2 to the outer wall of the tracheal tube 1, reducing the time for installing the bite block 2 and preventing the patient from biting the tube after the laryngoscope is removed.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
