Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a device for supporting and fixing endotracheal tubes. Background Technology

[0002] In existing technologies, endotracheal intubation refers to an emergency rescue technique that inserts a specially designed endotracheal tube through the mouth or nose and into the trachea via the glottis. This technique provides effective conditions for ventilation and oxygenation, airway suction to prevent aspiration, maintaining airway patency, and providing effective assisted breathing. Endotracheal intubation is commonly used in situations such as general anesthesia, respiratory failure, airway protection, airway obstruction, neuromuscular diseases, cardiopulmonary resuscitation, and intensive care. After intubation, a relatively long tube remains outside the body. In these situations, ensuring the stability and safety of the endotracheal tube is crucial to avoid potential risks caused by tube displacement or dislodgement.

[0003] Currently, the standard clinical method for fixation and support involves wrapping a strap around the dental splint, from behind the ear to the back of the head. This method cannot be adjusted for tightness; too loose and the tube may dislodge, too tight and it may leave marks on the patient's ear and cheek. Prolonged neglect can lead to medical device-related pressure injuries and adverse events. Another method is to use adhesive tape in a butterfly shape to fix the tube around the patient's mouth. While simple and easy to use, this method lacks stability and is prone to dislodgement. There is also a risk of discomfort or even allergic reactions around the patient's lips due to the tape.

[0004] Currently, the endotracheal intubation fixation devices routinely used in clinical practice still have the following drawbacks:

[0005] 1. Insufficient comfort: Currently, commonly used fixation devices in clinical practice often come with a mouthguard, which may cause discomfort to the patient's mouth during long-term use, especially in cases where long-term intubation is required, particularly in the face, oral cavity, or cheek area.

[0006] 2. Skin damage: The straps used to fix the tubes may cause skin pressure, and long-term use may cause skin ulcers or pressure sores, especially in elderly patients or patients with sensitive skin.

[0007] 3. Insecure fixation: When the patient is agitated, an insecure device may cause the endotracheal tube to shift, which is very dangerous for the patient, especially for critically ill patients.

[0008] 4. Different patients have different facial and oral anatomy, and some fixation devices may not be well adapted to all patients, resulting in poor fixation effect.

[0009] CN205215893U discloses a headgear-type endotracheal tube fixing device, mainly composed of a headgear and an endotracheal tube fixing device. Two fixing straps first pass through the rolled edge of the headgear, and then through the perforations of the endotracheal tube fixing device to connect the headgear and the endotracheal tube fixing device. The endotracheal tube fixing device consists of a panel body 1, an endotracheal tube protection tube 2, and an endotracheal tube fixing clip 3. The two fixing straps fix the panel body 1 three-dimensionally from the top of the person's head and the back of the neck, i.e., the horizontal plane and the vertical plane, respectively, to ensure the stability of the endotracheal tube.

[0010] However, this headgear-style endotracheal tube fixation device is relatively complex, making it inconvenient for patients to wear, as it requires two parts to be perforated and assembled. The back of the headgear has a hairnet, which is prone to slipping and is not conducive to securing the endotracheal tube. Utility Model Content

[0011] The present invention aims to solve the above-mentioned technical problems to at least a certain extent.

[0012] The purpose of this invention is to provide a device with a simple and reasonable structure and stable and reliable use for supporting and fixing endotracheal tubes.

[0013] The technical solution adopted by this utility model to solve its technical problem is: a device for supporting and fixing an endotracheal tube, comprising:

[0014] The headgear body includes multiple fixing straps, which are respectively wrapped around the patient's head and neck, and the fixing straps are provided with elastic buckles;

[0015] The intubation support is mask-shaped, with both sides of the intubation support fixed to and detachable from the headgear body. A head opening is formed between the intubation support and the headgear body, and the intubation support is provided with a support groove.

[0016] The cannula fixing part includes a first fixing block, which is fixed to and detachable from the cannula support part. The first fixing block is provided with a fixing groove, which together with the support groove forms a cannula fixing hole.

[0017] Before use, the endotracheal tube is inserted into the patient's mouth. After insertion, this invention can be used to support and fix the endotracheal tube. During use, the patient's head enters through the head opening, and the fixing straps are wrapped around the patient's head and neck. The fixing straps are adjusted using the elastic buckles to ensure a secure fit and patient comfort. The tube support is positioned against the patient's mouth, and the portion of the endotracheal tube outside the mouth is inserted into the support groove of the tube support. Then, both sides of the tube support are fixed to the head cover. The first fixing block is installed from below the endotracheal tube, fixing it to the tube support. The fixing groove and the support groove together form a tube fixing hole, securing the endotracheal tube, which then extends out from the fixing hole.

[0018] The headgear of this invention is adjustable via a snap-lock mechanism, making it suitable for different patient head shapes and ensuring a secure fit. Compared to existing adhesive tape and bite blocks, the headgear and endotracheal tube support provide greater patient comfort, preventing prolonged pressure on the face, ears, mouth, or cheeks, thus avoiding skin ulcers or medical device-related pressure injuries. The endotracheal tube is supported and secured by both the endotracheal tube support and fixation components, ensuring greater stability and preventing displacement that could lead to medical accidents.

[0019] In a preferred embodiment, the endotracheal tube fixing part includes a second fixing block, which is fixed to and detachable from the endotracheal tube support part, and is located above the first fixing block. The second fixing block, positioned above the first fixing block, further secures the endotracheal tube. Furthermore, the fixing of the second fixing block to the endotracheal tube support part increases the support force of the endotracheal tube support part, ensuring that the endotracheal tube is supported both above and below, preventing the endotracheal tube support part from collapsing, and thus effectively preventing the endotracheal tube from collapsing and dislodging, keeping it in the correct position.

[0020] More preferably, the intubation tube fixing part includes a limiting block, the first fixing block is provided with a slider, the limiting block is provided with a sliding groove, the slider is engaged in the sliding groove and can slide relative to it, the limiting block is provided with a first limiting groove, and the second fixing block is provided with a second limiting groove. The first limiting groove and the second limiting groove together form an intubation tube limiting hole. Since the diameter of the endotracheal tube may vary slightly among different patients, for adult patients, a diameter of 7-8 mm is usually appropriate. The fixing hole cannot match all sizes of endotracheal tubes, resulting in a certain gap between the endotracheal tube and the fixing hole, which leads to insufficient tightness of the endotracheal tube and possible displacement under external force. Therefore, a limiting block is added, and the size of the limiting hole is controlled by sliding the slider, so that the limiting hole can better match the size of the endotracheal tube. In other words, the limiting hole further fixes the endotracheal tube on the basis of the fixing hole, making it more stable.

[0021] More preferably, the limiting block is provided with a threaded hole and a fastening screw, and the threaded hole and the fastening screw are threadedly fixed together. The fastening screw engages with the threaded hole, and the rotation of the thread causes the limiting block to rise or fall slightly, thereby controlling the tightness between the slider and the slide groove, so that the limiting block can be positioned at the desired location and stop sliding. When needed, the fastening screw can also be loosened, allowing the limiting block to slide to the desired position.

[0022] In a preferred embodiment, the cannula support and the headgear body, the first fixing block and the cannula support, and the second fixing block and the cannula support are all fixed and detachable by snap fasteners. The snap fasteners include a button head and a button hole, featuring a simple structure, secure fixing, and convenient assembly and disassembly.

[0023] In a preferred embodiment, the intubation support is provided with multiple ventilation holes. These ventilation holes ensure that the intubation support does not impede the patient's breathing, facilitate carbon dioxide expulsion, and increase breathability and comfort.

[0024] In a preferred embodiment, a support block is provided on the outer side of the intersection of the fixing straps. The support block is preferably made of plastic material to increase the structural strength and support force between the fixing straps, while providing a support point for easy adjustment of the fixing straps.

[0025] In a preferred embodiment, flexible padding layers are provided on the inner side of the intersection of the fixation straps and on the inner side of the cannula support. These flexible padding layers increase comfort for the patient's head, face, and mouth, and prevent imprints.

[0026] The beneficial effects of this utility model are:

[0027] 1. The headgear body can be adjusted using elastic buckles to fit different patient head shapes and ensure a secure fit;

[0028] 2. Compared with adhesive tape and bite block, the headgear body and intubation support can make patients more comfortable and avoid prolonged pressure on the face, mouth or cheek area, thereby avoiding skin ulcers or medical device-related pressure injuries.

[0029] 3. The endotracheal tube is supported and fixed by both the tube support and the tube fixation part, which makes the endotracheal tube more stable and avoids displacement that could lead to medical accidents.

[0030] 4. The second fixing block is fixed to the intubation support part, which can increase the support force of the intubation support part on the endotracheal tube, ensure that the endotracheal tube can be supported from above and below, prevent the intubation support part from collapsing, and thus effectively prevent the endotracheal tube from collapsing and dislodging, keeping it in the correct position.

[0031] 5. Add a limiting block and control the size of the limiting hole by sliding the slider so that the limiting hole can better match the size of the endotracheal tube. In other words, the limiting hole further fixes the endotracheal tube on the basis of the fixed hole, making it more stable.

[0032] 6. The ventilation holes ensure that the intubation support does not affect the patient's breathing, which helps the patient expel carbon dioxide and increases breathability and comfort.

[0033] 7. The support blocks increase the structural strength and support force between the fixing straps, while also providing support points to facilitate the adjustment of the fixing straps;

[0034] 8. The flexible padding layer can increase the comfort of the patient's head, face and mouth, and prevent imprints. Attached Figure Description

[0045] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the present invention. To better illustrate the embodiments, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0046] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] like Figures 1 to 10 As shown, the present invention provides a device 100 for supporting and fixing an endotracheal tube, comprising a headgear body, a tube support part, and a tube fixing part.

[0048] The headgear includes multiple securing straps 101, which are respectively wrapped around the patient's head and neck. Each strap 101 has an elastic buckle 102. The headgear itself is a lightweight frame structure that does not impose additional burden on the patient. Its design conforms to the shape of the human head, fitting the curves of the patient's head and neck to reduce discomfort and pressure, thus improving comfort. The securing straps 101 are made of soft and elastic materials, such as medical-grade silicone or nylon, ensuring a close fit to the skin and reducing friction. The securing straps 101 are adjustable via the elastic buckles 102, allowing them to wrap around the patient's head and neck and be adjusted according to the size of the patient's head and neck, ensuring the device is stable and fits the head without being too tight.

[0049] The elastic buckle 102 allows medical staff to quickly fix and loosen the strap, saving time and simplifying the operation. The elastic buckle 102 is preferably positioned in the middle of the fixing strap 101 for easy operation by medical staff. The elastic buckle 102 should not be positioned at the bottom of the head to avoid causing discomfort to the patient.

[0050] In this embodiment, a support block 103 is provided on the outer side of the intersection of the fixing straps 101. The support block 103 is preferably made of plastic material to increase the structural strength and support force between the fixing straps 101, while providing a support point to facilitate the adjustment of the fixing straps 101.

[0051] The endotracheal tube support is mask-shaped, with both sides fixed to and detachable from the headgear body. A head opening 104 is formed between the endotracheal tube support and the headgear body, and the endotracheal tube support has a support groove 105. The endotracheal tube support is preferably made of transparent plastic and is mask-shaped, providing support for the endotracheal tube 106 (which is actually quite long; only a small section is shown in the figure) and leaving a certain gap between it and the mouth to avoid putting pressure on the patient's face.

[0052] In this embodiment, the intubation support is provided with multiple ventilation holes 107. The ventilation holes 107 ensure that the intubation support does not affect the patient's breathing, facilitate the patient's expulsion of carbon dioxide, and increase breathability and comfort.

[0053] In this embodiment, flexible padding layers (not shown) are provided on the inner side of the intersection of the fixation straps 101 and the inner side of the cannula support. These flexible padding layers increase the comfort of the patient's head, face, and mouth, and prevent imprints. The flexible padding layers are made of soft materials such as sponge or silicone.

[0054] The cannula fixing part includes a first fixing block 108, which is fixed to the cannula support part and can be disassembled. The first fixing block 108 is provided with a fixing groove 109, which together with the support groove 105 forms a cannula fixing hole.

[0055] Before use, the endotracheal tube 106 is inserted into the patient's mouth. After insertion, the present invention can be used to support and fix the endotracheal tube 106. During use, the patient's head enters through the head opening 104, and the fixing straps 101 are wrapped around the patient's head and neck. The fixing straps 101 are adjusted using the elastic buckles 102 to ensure the headgear body is securely fixed to the patient and keeps the patient comfortable. The tube support is positioned against the patient's mouth, and the portion of the endotracheal tube outside the mouth is inserted into the support groove 105 of the tube support. Then, both sides of the tube support are fixed to the headgear body. The first fixing block 108 is installed from below the endotracheal tube 106, fixing it to the tube support. The fixing groove 109 and the support groove 105 together form a tube fixing hole, securing the endotracheal tube 106, meaning the endotracheal tube 106 extends from the tube fixing hole.

[0056] The headgear body of this invention can be adjusted via the elastic buckle 102, thus adapting to different patient head shapes and providing a secure hold. Compared to adhesive tape and bite blocks, the headgear body and intubation support provide greater patient comfort, avoiding prolonged pressure on the face, mouth, or cheek areas, thereby preventing skin ulcers or medical device-related pressure injuries. The endotracheal tube 106 is supported and secured by both the intubation support and fixation parts, ensuring greater stability and preventing displacement that could lead to medical accidents.

[0057] In this embodiment, the endotracheal tube fixing part includes a second fixing block 110. The second fixing block 110 is fixed to the endotracheal tube support part and can be detached. The second fixing block 110 is located above the first fixing block 108. The second fixing block 110, located above the first fixing block 108, can further fix the endotracheal tube 106. Furthermore, the fixing of the second fixing block 110 to the endotracheal tube support part can increase the supporting force of the endotracheal tube support part on the endotracheal tube 106, ensuring that the endotracheal tube 106 is supported both above and below, preventing the endotracheal tube support part from collapsing, and thus effectively preventing the endotracheal tube 106 from collapsing and dislodging, keeping it in the correct position.

[0058] In this embodiment, the endotracheal tube fixing part includes a limiting block 111. The first fixing block 108 is provided with a slider 112, and the limiting block 111 is provided with a sliding groove 113. The slider 112 is engaged in the sliding groove 113 and can slide relative to it. The limiting block 111 is provided with a first limiting groove 114, and the second fixing block 110 is provided with a second limiting groove 115. The first limiting groove 114 and the second limiting groove 115 together form an endotracheal tube limiting hole. Since the diameter of the endotracheal tube 106 may vary slightly among different patients, a diameter of 7-8 mm is usually preferable. The fixing hole cannot match all sizes of endotracheal tubes 106, resulting in a certain gap between the endotracheal tube 106 and the fixing hole. This can cause the endotracheal tube 106 to be insufficiently secure and may shift under external force. Therefore, a limiting block 111 is added, and the size of the limiting hole is controlled by sliding slider 112, so that the limiting hole can better match the size of the endotracheal tube 106. In other words, the limiting hole further fixes the endotracheal tube 106 on the basis of the fixed hole, making it more stable.

[0059] In this embodiment, the limiting block 111 is provided with a threaded hole 116 and a fastening screw 117, and the threaded hole 116 and the fastening screw 117 are threadedly fixed together. The fastening screw 117 is threadedly engaged with the threaded hole 116, and the threaded rotation causes the limiting block 111 to rise or fall slightly, thereby controlling the tightness between the slider 112 and the slide groove 113, so that the limiting block 111 can be positioned at the required position and no longer slide. When needed, the fastening screw 117 can also be loosened, allowing the limiting block 111 to slide to the desired position.

[0060] In this embodiment, the cannula support and the headgear body, the first fixing block 108 and the cannula support, and the second fixing block 110 and the cannula support are all fixed and detachable by snap fasteners. The snap fasteners include a button head and a button hole, featuring a simple structure, stable fixation, and convenient assembly and disassembly.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
