Description

Technical Field

[0001] This utility model relates to medical devices and equipment, and more specifically, to a dental pad for fixing insertion tubes. Background Technology

[0002] In clinical nursing, especially in the resuscitation and treatment of critically ill patients, endotracheal intubation is frequently required. Endotracheal intubation refers to the technique of inserting a specially designed endotracheal tube through the glottis into the trachea. It plays a crucial role in the resuscitation of critically ill patients, providing favorable conditions for treating respiratory arrest, airway obstruction, hypoxia, or insufficient ventilation.

[0003] In existing techniques, a bite block is typically placed between the patient's upper and lower incisors after successful intubation to prevent unconscious biting movements from abrading or even blocking the endotracheal tube, thus preventing gas exchange and potentially life-threatening situations. However, since the bite block and endotracheal tube cannot be directly connected, the bite block is usually secured to the patient's face with adhesive tape for support. However, after prolonged use, the tape can loosen, leading to relative movement between the bite block and the endotracheal tube, compromising the effectiveness of the endotracheal tube's fixation. Utility Model Content

[0004] To overcome the problem of poor fixation between the bite pad and the endotracheal tube in the prior art, this utility model provides a bite pad that can fix the endotracheal tube on the bite pad.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a dental pad for fixing a cannula, including an occlusal portion, a bent handle portion connected to the occlusal portion, and an mounting component installed on the bent handle portion; the bent handle portion is provided with a straight segment connected to the occlusal portion and a curved segment connected to the straight segment, the straight segment is provided with a first engaging portion and an annular fixing strap for wrapping around the patient's neck; the first engaging portion is located on the side opposite to the bending direction of the curved segment, the mounting component is provided with a claw portion that engages with the first engaging portion; the mounting component is provided with a slot for the cannula to pass through and a locking component for fixing the cannula within the slot; the annular fixing strap is located between the first engaging portion and the occlusal portion.

[0006] In the above technical solution, the occlusal part is placed into the patient's mouth, keeping the patient's mouth open. The bent handle is located outside the patient's mouth, with the curved section positioned above the patient's cheek. This allows it to not obstruct the endotracheal tube while simultaneously hooking the patient's lips when swallowing, preventing accidental swallowing. There are two ways to use the mounting component. One method is to fix the mounting component to the first engaging part using the locking mechanism. Since the first engaging part is located on the side opposite to the curvature of the curved section, the through-hole is located above the patient's mouth. Then, the tube, such as the endotracheal tube, is inserted through the through-hole into the patient's body. Once the endotracheal tube is in place, it is secured using the locking assembly, thus fixing the endotracheal tube to the bite block. The other method is to pre-fix the mounting component to the endotracheal tube using the locking assembly, then insert the endotracheal tube into the patient's body. Once the endotracheal tube is in place, the locking mechanism of the mounting component engages with the first engaging part. Under normal circumstances, with a skilled doctor, the depth of endotracheal tube insertion can be determined. Therefore, pre-installing the mounting device on the endotracheal tube will not significantly affect the fixation of the mounting device on the first locking part. After use, the bite block can be removed by bending the handle.

[0007] The ring-shaped fixation strap can be placed around the patient's neck to further secure the dental splint. To avoid the ring-shaped fixation strap interfering with the installation of the fitting, the ring-shaped fixation strap needs to be placed between the first occlusal part and the occlusal part.

[0008] Preferably, the claw portion is a protrusion, and the axis of the protrusion is perpendicular to the axis of the latch portion; the first engaging portion is provided with a groove that conforms to the shape of the protrusion. The protrusion can be T-shaped, dovetail-shaped, or arc-shaped. Since the axis of the protrusion is perpendicular to the axis of the latch portion, the mounting component is inserted into the groove in a horizontal direction. Compared to inserting it vertically, this avoids the mounting component from moving downwards under gravity and detaching from the bent handle.

[0009] Preferably, the protrusion and the groove are in a transitional fit. This transitional fit allows for a tighter connection between the two while minimizing resistance during installation.

[0010] Preferably, the cross-section of the groove is arc-shaped. The arc-shaped groove and the raised strip have no sharp edges, making installation easier. At the same time, the arc-shaped groove can cover a larger area of ​​the raised strip, preventing it from falling out of the groove.

[0011] Preferably, the mounting component has a second engaging portion on the side away from the claw portion. The structure of the second engaging portion is identical to that of the first engaging portion. Different mounting components are connected through the claw portion and the second engaging portion. Multiple mounting components can be installed as needed, and they can be spliced ​​together. For example, if it is necessary to aspirate oral secretions or blood, one or two mounting components can be added, and the aspiration tube can also pass through the claw portion and be fixed by the locking assembly. This allows the dental splint to simultaneously fix multiple different tubes.

[0012] Preferably, the radial cross-section of the bayonet portion is arc-shaped; the locking assembly includes a connecting strap located on one side of the opening of the bayonet portion and having a first ratchet portion, and a connecting hole located on the other side of the opening of the bayonet portion and having a second ratchet portion. The connecting strap is inserted into the connecting hole, and the first and second ratchet portions engage. After a tubing, such as an endotracheal tube, is inserted into the bayonet portion, the connecting strap is inserted into the connecting hole. Depending on the diameter of the tubing, the length through which the connecting strap can pass varies. When the connecting strap tightens the tubing, the first and second ratchet portions engage, preventing the connecting strap from coming out and maintaining the tubing locked within the bayonet portion.

[0013] Preferably, the straight segment is provided with a sliding hole, and the engaging part is slidably connected to the straight segment. The end of the engaging part is provided with a limiting part to prevent the engaging part from dislodging from the sliding hole. The engaging part can slide along the sliding hole to adjust its extension length, thereby changing the position of the installer. The position of the installer relative to the oral cavity can be adjusted according to actual needs, facilitating the insertion of the tube.

[0014] Preferably, both the top and bottom ends of the occlusal portion are provided with occlusal grooves, and a silicone layer is disposed within the occlusal grooves. The silicone layer is made of a soft material that can wrap around the patient's teeth. Even if the patient makes an unconscious biting motion and their teeth collide with the dental pad, it can still provide a cushioning effect, reducing the risk of the patient's teeth becoming loose, falling out, or bleeding.

[0015] Preferably, the two ends of the annular fixing strap are welded to the bent handle to form an annular shape. Since the dental pad is a disposable item, connecting the annular fixing strap by welding provides high connection strength, and the process is simple and low-cost.

[0016] Compared to existing technologies, the advantages are: the bite block, with the addition of an installation component, can fix the endotracheal tube, achieving a secure connection. Therefore, the endotracheal tube remains fixed throughout the bite block's use, preventing relative movement. The bite block can also be worn around the patient's neck with a loop fastener to further prevent it from falling off. Attached Figure Description

[0021] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0022] Example 1

[0023] like Figure 1-2 The image shows a dental splint for securing a cannula, comprising an occlusal portion 1, a bent handle portion 2 connected to the occlusal portion 1, and a mounting member 3 mounted on the bent handle portion 2. The bent handle portion 2 has a straight segment 201 connected to the occlusal portion 1 and a curved segment 202 connected to the straight segment 201. The straight segment 201 has a first engaging portion 203 and an annular fixing strap 204 for encircling the patient's neck. The first engaging portion 203 is located on the side opposite to the bending direction of the curved segment 202. The mounting member 3 has a locking claw portion 301 that engages with the first engaging portion 203. The mounting member 3 has a slot portion 302 through which the cannula passes and a locking component 303 for fixing the cannula within the slot portion 302. The annular fixing strap 204 is located between the first engaging portion 203 and the occlusal portion 1. The two ends of the annular fixing strap 204 are fused to the bent handle portion 2 to form an annulus. Since dental pads are disposable, the circular fixing bands 204 are connected by welding, resulting in high connection strength and a simple and low-cost process.

[0024] Specifically, the claw portion 301 is a protruding strip, and the axis of the protruding strip is perpendicular to the axis of the latch portion 302; the first engaging portion 203 is provided with a groove 2031 that fits the shape of the protruding strip. The protruding strip can be T-shaped, dovetail-shaped, or arc-shaped. The axis of the protruding strip is perpendicular to the axis of the latch portion 302. The mounting member 3 is inserted into the groove 2031 by moving horizontally. Compared with inserting it into the groove 2031 vertically, this avoids the mounting member 3 from moving downwards and detaching from the bent handle portion 2 due to gravity.

[0025] In this embodiment, the protrusion and the groove 2031 are in a transitional fit. This transitional fit allows for a tighter connection between the two, while minimizing resistance during installation. The groove 2031 has a curved cross-section. The curved groove 2031 and the protrusion have no sharp edges, making installation easier. Simultaneously, the curved groove 2031 can cover a larger area of ​​the protrusion, preventing it from falling out of the groove 2031.

[0026] The locking component 303 is slidably connected to the side wall of the mounting part 3, and the sliding direction is perpendicular to the axis of the bayonet portion 302. One end of the locking component 303 is located inside the bayonet portion 302, and the other end extends to the outside of the side wall of the mounting part 3. Several locking components 303 are provided and are equidistantly distributed along the axis of the bayonet portion 302. When the mounting part 3 and the pipe can be fixed, the locking component 303 is pressed externally to slide into the bayonet portion 302, so that the locking component 303 squeezes the pipe, thereby fixing the pipe in the bayonet portion 302. Without the action of external force, the pipe is restricted by the locking component 303 and cannot move relative to the mounting part 3.

[0027] In this embodiment, a second engaging portion 304 is provided on the side of the mounting member 3 away from the claw portion 301. The structure of the second engaging portion 304 is consistent with the structure of the first engaging portion 203. Different mounting members 3 are connected to each other through the claw portion 301 and the second engaging portion 304. Multiple mounting members 3 can be installed as needed, and the mounting members 3 can be spliced ​​together. If it is necessary to aspirate oral secretions or blood from the patient, one or two mounting members 3 can be added, and the aspiration tube can also pass through the jaw portion 302 and be fixed by the locking component 303. This realizes the function of simultaneously fixing multiple different tubes in the dental splint.

[0028] The radial cross-section of the bayonet portion 302 is arc-shaped. The locking assembly includes a connecting strap 3031 located on one side of the opening of the bayonet portion 302 and provided with a first ratchet portion 3311, and a connecting hole 3032 located on the other side of the opening of the bayonet portion 302 and provided with a second ratchet portion 3321. The connecting strap 3031 is inserted into the connecting hole 3032, and the first ratchet portion 3311 and the second ratchet portion 3321 are engaged. After a tubing, such as an endotracheal tube, is inserted into the bayonet portion 302, the connecting strap 3031 is inserted into the connecting hole 3032. The length through which the connecting strap 3031 can pass varies depending on the diameter of the tubing. When the connecting strap 3031 tightens the tubing, the first ratchet portion 3311 and the second ratchet portion 3321 are engaged, preventing the connecting strap 3031 from coming out and maintaining the state in which the tubing is locked within the bayonet portion 302.

[0029] In this embodiment, the straight segment 201 is provided with a sliding hole, and the engaging portion 203 is slidably connected to the straight segment 201. The end of the engaging portion 203 is provided with a limiting portion 2032 for preventing the engaging portion 203 from dislodging from the sliding hole. The engaging portion 203 can slide along the sliding hole to adjust its extended length, thereby changing the position of the installer. The position of the installer relative to the oral cavity can be adjusted according to actual needs, facilitating the insertion of the tube.

[0030] The working principle of this embodiment is as follows: The biting part 1 is placed into the patient's mouth, keeping the patient's mouth open. The bent handle 2 is located outside the patient's mouth, with the curved section 202 positioned above the patient's cheek. This allows the endotracheal tube to remain in place while hooking the patient's lips when the biting part 1 is swallowed, preventing accidental swallowing. The mounting part 3 is fixed to the first engaging part 203 via the claw part 301. Since the first engaging part 203 is located on the side opposite to the bending direction of the curved section 202, the locking part is positioned above the patient's mouth. Then, a tube, such as an endotracheal tube, is inserted into the patient's body through the through-hole. Once the endotracheal tube is in place, it is locked into the locking part and secured by the locking component 303, thus fixing the endotracheal tube to the bite block. After use, the bite block can be removed via the bent handle 2.

[0031] The ring-shaped fixing band 204 can be placed around the patient's neck to further secure the dental splint. In order to avoid the ring-shaped fixing band 204 affecting the installation of the mounting part 3, the ring-shaped fixing band 204 needs to be placed between the first engaging part 203 and the occlusal part 1.

[0032] The beneficial effects of this embodiment are as follows: By adding the mounting component 3, the endotracheal tube can be fixed in place, achieving a fixed connection of the endotracheal tube. Therefore, the endotracheal tube remains fixed throughout the entire use of the bite pad and will not move relative to the bite pad. The bite pad can be worn around the patient's neck with a ring-shaped fixing strap to further prevent it from falling off.

[0033] Example 2

[0034] Embodiment 3 of a dental pad for fixing a cannula differs from Embodiment 1 or Embodiment 2 in that both the top and bottom ends of the occlusal portion 1 are provided with occlusal grooves 101, and a silicone layer 1011 is disposed within the occlusal grooves 101. The silicone layer 1011 is made of a soft material that can wrap around the patient's teeth. Even if the patient makes an unconscious biting motion and their teeth collide with the dental pad, it can still provide a cushioning effect, reducing the risk of the patient's teeth becoming loose, falling out, or bleeding.
