Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, specifically to a tracheal tube with a dental pad. Background Technology

[0002] Endotracheal intubation is a crucial procedure for treating patients under general anesthesia, experiencing respiratory distress, undergoing cardiopulmonary resuscitation, and with accompanying respiratory dysfunction. Inserting an endotracheal tube through the mouth and glottis into the trachea provides optimal conditions for airway patency, ventilation, oxygenation, airway suction, and prevention of aspiration, making it a widely used treatment method in airway management. Because endotracheal tubes are soft, in clinical nursing care, to prevent patients from biting down on the tube upon initial anesthesia recovery or due to agitation or discomfort, a firm bite block should be placed between the patient's upper and lower teeth after insertion.

[0003] Currently, the catheter and bite block are attached to the patient's skin using tape or cloth strips. Using tape easily damages the mucous membranes at the corners of the mouth and the roof of the mouth. Each time the tape is removed and changed, it pulls on the airway, increasing patient pain and airway mucosal damage, posing a significant safety hazard. Furthermore, the tape needs to be wrapped many times, making the process cumbersome, time-consuming, and labor-intensive, hindering timely treatment. Slight mishaps can cause the catheter and bite block to detach, leading to catheter displacement or being bitten by the patient, causing considerable inconvenience in clinical practice. Therefore, improvements and developments are needed to address these issues. Utility Model Content

[0004] This invention provides a tracheal tube with a bite block, solving the problem of harm caused to patients by traditional adhesive tape directly adhering to their skin. The specific implementation method is as follows:

[0005] A tracheal tube with a bite block includes a tube body and a bite block body movably disposed on the tube body. The bite block body has a perforation, through which the tube body passes and is fitted onto the bite block body. The bite block body includes a threaded cap, a retaining ring, and a compression member sequentially fitted onto the tube body. The bite block body has a threaded connector axially disposed corresponding to the perforation position. The threaded cap is threadedly connected to the threaded connector. The compression member is disposed between the threaded cap and the threaded connector. The retaining ring abuts against the threaded connector and the compression member respectively. The retaining ring is a non-closed annular structure with a slit. The inner ring of the retaining ring has retaining teeth. During the relative tightening of the threaded cap and the threaded connector, the compression member deforms and presses against the retaining ring, causing the slit of the retaining ring to contract so that the retaining teeth abut against the tube body, thereby locking the bite block body onto the tube body.

[0006] As a further embodiment of this utility model, the retaining teeth are formed with a contact surface, which is inclined in the axial direction of the retaining ring.

[0007] As a further embodiment of this utility model, multiple locking teeth are provided, and the multiple locking teeth are arranged at intervals along the circumference of the locking ring.

[0008] As a further embodiment of this utility model, the threaded connector is stepped to form a groove, and the extrusion member and the retaining ring are sequentially fitted into the groove, with the retaining ring abutting against the bottom of the groove.

[0009] As a further embodiment of this utility model, the threaded connector is provided with a guide groove, the guide groove being adjacent to the top surface of the threaded connector, and the extrusion member is provided with a slider corresponding to the guide groove, the slider being slidably disposed in the guide groove.

[0010] As a further embodiment of this utility model, the extrusion member is formed with a rigid connection portion, and the slider is disposed on the outer wall of the rigid connection portion.

[0011] As a further embodiment of this utility model, at least two sliders are provided, and the two sliders are arranged at intervals along the circumferential direction of the extruder.

[0012] As a further embodiment of this utility model, the main body of the dental pad includes a pad plate and a dental pad portion disposed on the pad plate, wherein the perforation passes through the pad plate and the dental pad portion in sequence.

[0013] As a further embodiment of this utility model, the pad has an arc-shaped contact surface, and the dental pad portion is disposed on the arc-shaped contact surface.

[0014] As a further embodiment of this utility model, the main body of the dental pad also includes two fixing straps that can be bonded to or separated from each other, and the fixing straps are detachably connected to the pad plate.

[0015] Due to the adoption of the above technical solutions, the beneficial technical effects of this utility model are:

[0016] This invention is safer than traditional tape fixation methods. It can solve the problem of damage to the mucosa at the corner of the patient's mouth and the palate caused by the tape tearing and pulling the main body of the catheter, thereby effectively avoiding the harm to the patient caused by tape replacement.

[0017] This invention uses locking components on the main body of the dental pad to firmly fix it to the main body of the catheter, ensuring a tight connection between the main body of the dental pad and the main body of the catheter, avoiding the risk of the main body of the catheter shifting or being bitten by the patient, and also simplifying the operation process and improving work efficiency.

[0018] The main body of this invention is fitted onto the main body of the catheter. The main body of the dental pad can move along the direction of the catheter and be locked in the desired position. The position can be adjusted according to the condition of different patients, thereby enhancing its adaptability and flexibility. Attached Figure Description

[0031] The specific embodiments of this utility model are described below with reference to the accompanying drawings and examples:

[0032] It should be noted that the structures, proportions, sizes, etc. shown in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which the present invention can be implemented. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0033] Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0034] Example 1, combined with Figures 1 to 5 As shown, this embodiment provides a tracheal tube with a bite block, including a tube body 1 and a bite block body 5 movably disposed on the tube body 1. The bite block body 5 has a perforation 514, through which the tube body 1 passes and is fitted onto the bite block body 5. Since the distance from the occlusal position to the trachea varies among different patients, the design of the bite block body 5 being movable along the tube direction of the tube body 1 helps adjust the position of the bite block body 5 on the tube body 1 according to the insertion depth of the tube body 1. This ensures that the insertion port 12 of the tube body 1 is in the optimal position for the most effective gas exchange.

[0035] In this embodiment, a cuff 2 is provided near the insertion port 12 of the catheter body 1. The cuff 2 fits tightly against the tracheal wall, thereby ensuring the airway seal of the patient and effectively preventing gas leakage. The catheter body 1 has a chamber for accommodating various tubing, including an inflation tube 4 and a suction tube 3. The first end of the inflation tube 4 is connected to the cuff 2 and gas is injected into the cuff 2 to inflate it. The end of the inflation tube 4 passes through the chamber and extends to the outside of the catheter body 1. The inflation tube 4 can be connected to an external inflation device to inject gas into the cuff 2. The first end of the suction tube 3 is connected to the insertion port 12. The end of the suction tube 3 passes through the chamber and extends to the outside of the catheter body 1. The suction tube 3 can be connected to an external suction device to effectively clear secretions from the airway and maintain airway patency. The catheter body 1 is also provided with a connector 13 at the end of the catheter body 1, which can be connected to a standard anesthesia machine interface for connecting a ventilator, resuscitation bag, or other ventilation equipment. The catheter body 1 has scale markings 11 on its tube to help medical staff determine the depth of insertion of the catheter body 1 and ensure that its insertion port 12 is in the correct tracheal position.

[0036] Specifically, such as Figure 3 As shown, the dental pad body 5 includes a pad plate 51 and a dental pad portion 513 disposed on the pad plate 51. The perforation 514 passes through the pad plate 51 and the dental pad portion 513 in sequence. The pad plate 51 has a thin rectangular structure that fits the patient's perioral area. The dental pad portion 513 is placed inside the patient's oral cavity to help the patient bite. The dental pad portion 513 can be made of medical silicone. Medical silicone is relatively soft and can provide a certain cushioning effect, reducing potential damage to teeth and oral tissues. This effectively avoids the problem of the patient unconsciously biting down on the catheter body 1, which could lead to damage to the catheter body 1 and airway obstruction. In this way, it helps to protect the catheter body 1 from damage and maintain airway patency.

[0037] For example, the pad 51 has an arc-shaped contact surface, and the dental pad portion 513 is disposed on the arc-shaped contact surface. The cross-section of the pad 51 is arc-shaped. The arc-shaped design is more conducive to conforming to the patient's facial contours, providing more stable support, and reducing the problem of displacement of the dental pad body 5 due to patient movement or changes in head position, thereby helping to maintain the stability of the endotracheal tube position. The pad 51 and the dental pad portion 513 are also provided with a channel hole 511 penetrating both, through which the patient's oral secretions can be discharged, thereby ensuring oral hygiene.

[0038] Specifically, to fix the dental pad body 5 to the patient's head, the dental pad body 5 also includes two fixation straps 6 that can be bonded to or separated from each other. The fixation straps 6 are detachably connected to the pad plate 51. The fixation straps 6 are disposed on the pad plate 51, one of which has a rough surface at its tail and the other has a hook surface at its tail. The rough surface and the hook surface are bonded together to achieve the connection between the two fixation straps 6. Connection holes are provided at both ends of the pad plate 51. The heads of the two fixation straps 6 are respectively connected to the connection holes of the pad plate 51. The two fixation straps 6 are connected by bonding the rough surface and the hook surface, thereby fixing the dental pad body 5 and improving the stability of the catheter body 1.

[0039] Specifically, such as Figure 4 As shown, after the position of the dental pad body 5 is adjusted, it needs to be fixed onto the catheter body 1. Therefore, the dental pad body 5 includes a threaded cap 54, a retaining ring 52, and a pressing member that are sequentially fitted onto the catheter body 1. The dental pad body 5 has a threaded connector 512 axially provided at the position corresponding to the through hole 514. The threaded cap 54 is threadedly connected to the threaded connector 512. The pressing member is located between the threaded cap 54 and the threaded connector 512. The retaining ring 52 abuts against the threaded connector 512 and the pressing member respectively. The retaining ring 52 is a non-closed annular structure with a slit 521. The inner ring of the retaining ring 52 has retaining teeth 522. During the relative tightening of the threaded cap 54 and the threaded connector 512, the pressing member deforms and abuts against the retaining ring 52, causing the slit 521 of the retaining ring 52 to shrink so that the retaining teeth 522 abut against the catheter body 1, thereby locking the dental pad body 5 onto the catheter body 1.

[0040] For example, the threaded connector 512 is stepped to form a groove, and the extrusion member and retaining ring 52 are sequentially fitted into the groove, with the retaining ring 52 abutting against the bottom of the groove. The extrusion member and retaining ring 52 are disposed in the groove and screwed to the threaded connector 512 by a threaded sleeve 54, pressing the extrusion member and retaining ring 52 between the bottom of the groove and the threaded sleeve 54, so that the retaining ring 52 can grip the guide tube body 1 after being extruded.

[0041] For example, the extrusion component is set as an annular sealing ring 53. During the screwing process of the threaded sleeve 54 and the threaded connector 512, the threaded sleeve 54 extrudes the sealing ring 53, and the sealing ring 53 is compressed and deformed, which increases the radial pressure on the retaining ring 52, causing the opening 521 of the retaining ring 52 to shrink, and causing the retaining teeth 522 of the inner ring of the retaining ring 52 to abut more tightly against the outer wall of the conduit body 1, thereby improving the connection stability between the tooth pad body 5 and the conduit body 1.

[0042] For example, the retaining tooth 522 has an abutting surface that is inclined towards the axial direction of the retaining ring 52. When the retaining ring 52 is compressed, the bottom end of the abutting surface of the retaining tooth 522 gradually moves towards the catheter body 1, causing the retaining tooth 522 to deform and more firmly grasp the catheter body 1, thereby ensuring the stability of the dental pad body 5 and reducing the risk of airway injury or other complications that may be caused by accidental movement.

[0043] Preferably, multiple retaining teeth 522 are provided, and the multiple retaining teeth 522 are spaced apart along the circumference of the retaining ring 52. The multiple retaining teeth 522 can form multiple contact points with the catheter body 1, increasing the friction between the two, thereby helping to enhance the connection stability between the dental pad body 5 and the catheter body 1.

[0044] For example, combined Figure 4 , Figure 5 As shown, the threaded connector 512 has a guide groove 515, which is adjacent to the top surface of the threaded connector 512. The extrusion member has a slider 531 corresponding to the guide groove 515, and the slider 531 is slidably disposed in the guide groove 515. The slider 531 is disposed on the sealing ring 53, which has a rigid connection portion. The slider 531 is disposed on the outer wall of the rigid connection portion, which surrounds the outer wall of the sealing ring 53. The rigid connection portion can be made of rigid plastic, which helps to ensure the connection stability between the slider 531 and the sealing ring 53. The slider 531 is slidably disposed in the guide groove 515 to prevent the sealing ring 53 and the threaded sleeve 7 from rotating synchronously. The slider 531 is disposed on the outer wall of the rigid connection portion of the sealing ring 53 to prevent the sealing ring 53 from being damaged due to rotation, thereby maintaining its sealing performance.

[0045] Preferably, at least two sliders 531 are provided, and the two sliders 531 are arranged at intervals along the circumference of the extruder. In this embodiment, four sliders 531 are provided, and the four sliders 531 are arranged at equal intervals along the circumference of the hard connection part of the sealing ring 53, thereby further preventing the sealing ring 53 and the threaded sleeve 7 from rotating synchronously.

[0046] The working principle of this utility model is as follows: In specific operation, first determine the required insertion depth, insert the catheter body 1 into the patient's trachea, at which time the bite pad body 5 is in an unclamped state, allowing it to slide relative to the catheter body 1. After the catheter body 1 is inserted into the appropriate position, fix the bite pad body 5 according to the occlusal position. Specifically, the two fixing straps 6 are connected by bonding the rough and hook surfaces. During the screwing process between the threaded sleeve 54 and the threaded connector 512, the threaded sleeve 54 squeezes the sealing ring 53. The sealing ring 53 is compressed and deformed, which increases the radial pressure on the retaining ring 52, causing the opening 521 of the retaining ring 52 to shrink, and causing the retaining teeth 522 of the inner ring of the retaining ring 52 to more tightly abut against the outer wall of the catheter body 1, thereby fixing the bite pad body 5 to the catheter body 1. The connector 13 is connected to the external device, and the tracheal catheter works normally. The catheter body 1 is connected to the dental pad body 5, which can replace the method of fixing with tape, thereby effectively avoiding the harm to the patient caused by changing tape and improving safety and comfort.

[0047] Many other changes and modifications can be made without departing from the concept and scope of this utility model. It should be understood that this utility model is not limited to the specific embodiments, and the scope of this utility model is defined by the appended claims.
