Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to a disposable dental pad. Background Art

[0002] Some patients require endotracheal intubation to establish an artificial airway for mechanical ventilation due to severe hypoxemia or hypercapnia, or other reasons. Fixing the endotracheal tube is the first step after establishing the artificial airway. Because the endotracheal tube is in direct contact with the airway mucosa, the material of the endotracheal tube must be relatively soft. However, to prevent the patient's teeth from blocking the artificial airway, a bite block with a certain hardness is required to fix the teeth and maintain a certain distance between the upper and lower teeth. The bite block is also used to ensure the patient's normal breathing after general anesthesia and for gastroscopy intubation.

[0003] After searching, a Chinese patent with publication number CN213048834U mentioned a disposable dental pad, including a dental pad main body, a first limit block, a second limit block, a pipe socket and a protective component. A pipe socket is opened at the center of the end face of the dental pad main body, and the first limit block and the second limit block are connected to both sides of the dental pad main body. The protective component includes a first ring mounted on the outer end face of the dental pad main body, and second rings are connected and fixed on both sides of the first ring. The second rings are respectively mounted on the outer end faces of the first limit block and the second limit block and are movably connected to the first limit block and the second limit block. Floating pads are also provided at the upper and lower ends of the second ring; the teeth are placed between the two limit blocks and the roots of the teeth are protected by silicone rings to improve the comfort when wearing. In addition, when the upper and lower jaws are in contact with the floating pads, the floating pads elastically support the jaws, thereby avoiding prolonged squeezing of the jaws and reducing the occurrence of pressure sores.

[0004] However, the existing dental pad structures are mostly simple and are directly placed in the patient's mouth for use. With the development of social technology, the functionality of the trachea has become more and more, and the relative tube diameter has also increased. In addition, the size of the intubation tube reserved for some dental pads is limited and can only be used for the insertion of ventilation hoses. In addition, the tube diameter of the gastroscope is thicker, and the dental pad suitable for gastroscopy needs to be replaced. When the dental pad is engaged in the patient's mouth, the patient's tongue will block a certain line of sight, affecting the intubation work. The dental pad is not comprehensive enough in applicability, has a single structure, and has low work efficiency.

[0005] Therefore, those skilled in the art have proposed disposable dental pads to solve the problems raised in the background art. Utility Model Content

[0022] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] As attached Figure 1 To the attached Figure 4 As shown:

[0024] Embodiment 1: The present invention provides a disposable dental pad, comprising a first dental pad 1 , with an adjustment mechanism 2 for adjusting the dental pad expansion angle connected to the top of the first dental pad 1 , and a tongue depressing mechanism 3 for improving the intubation effect provided on the inner side of the first dental pad 1 .

[0025] The adjustment mechanism 2 greatly improves the working performance of the bite pad and improves the device structure. The telescopic column 4 and the screw adjuster 5 provided in the adjustment mechanism 2 can effectively adjust the expansion distance between the first bite pad 1 and the second bite pad 6, so that it is not only suitable for tracheal insertion, but also for gastroscopic intubation, laryngoscope and other tasks. The scope of application of the bite pad has been greatly improved, and the operation is simple and convenient, which is convenient for staff to use.

[0026] The tongue depressor mechanism 3 further improves the working performance of the dental pad and improves the efficiency of intubation to a certain extent. When the dental pad is engaged in the patient's mouth, the tongue depressor 10 provided in the tongue depressor mechanism 3 performs tongue depressing work through the movable shaft 9, thereby reducing the obstruction of vision and facilitating the staff to perform intubation work.

[0027] The adjustment mechanism 2 includes a telescopic column 4 , the outer side of the telescopic column 4 is connected to a screw adjuster 5 for adjusting the telescopic length of the telescopic column 4 , and one end of the telescopic column 4 is slidably connected to the inner side of the screw adjuster 5 .

[0028] The other end of the telescopic column 4 is fixedly connected to a second bite pad 6 that cooperates with the first bite pad 1 for occlusion.

[0029] A movable column 7 for cooperating with expansion adjustment is also provided above the first bite pad 1. The other end of the movable column 7 is fixedly connected to the bottom of the second bite pad 6. An elastic frame 8 is provided on the inner side of the first bite pad 1 and the second bite pad 6 to improve the intubation fixation effect.

[0030] The tongue depressor mechanism 3 includes a movable shaft 9 and a tongue depressor 10 . The movable shaft 9 is fixedly connected to the inner side of the first bite pad 1 .

[0031] The tongue depressor 10 is connected to the outer side of the movable shaft 9.

[0032] As can be seen from the above, the adjustment mechanism 2 includes a telescopic column 4 , the outer side of the telescopic column 4 is connected to a screw adjuster 5 for adjusting the telescopic length of the telescopic column 4 , and one end of the telescopic column 4 is slidably connected to the inner side of the screw adjuster 5 .

[0033] The other end of the telescopic column 4 is fixedly connected to a second bite pad 6 that cooperates with the first bite pad 1 for occlusion.

[0034] The telescopic column 4 and the screw adjuster 5 provided in the adjustment mechanism 2 can effectively adjust the expansion distance between the first bite pad 1 and the second bite pad 6, so that it is not only suitable for tracheal insertion, but also for gastroscopic intubation, laryngoscope and other tasks, and the scope of application of the bite pad is greatly improved.

[0035] One end of the telescopic column 4 is slidably connected to the inner side of the screw adjuster 5, and the other end of the telescopic column 4 is fixedly connected to the second bite pad 6 that engages with the first bite pad 1. The screw adjuster 5 is connected to the outer side of the telescopic column 4. When the screw adjuster 5 is twisted forward, the telescopic column 4 extends outward along the inner side of the screw adjuster 5, and one end of the telescopic column 4 is fixedly connected to the surface of the first bite pad 1 and the second bite pad 6, thereby driving the first bite pad 1 and the second bite pad 6 to expand outward away from the screw adjuster 5 until the pipe to be inserted can pass through the elastic frame 8 normally. When the expansion distance of the bite pads is reduced, the screw adjuster 5 is twisted in the opposite direction. At this time, the telescopic column 4 drives the first bite pad 1 and the second bite pad 6 to move closer to the screw adjuster 5 to reduce the expansion distance.

[0036] A movable column 7 for cooperating with expansion adjustment is also provided above the first bite pad 1. The other end of the movable column 7 is fixedly connected to the bottom of the second bite pad 6. An elastic frame 8 is provided on the inner side of the first bite pad 1 and the second bite pad 6 to improve the intubation fixation effect.

[0037] The upper and lower ends of the movable column 7 are fixedly connected to the upper and lower surfaces of the first bite pad 1 and the second bite pad 6 respectively, providing auxiliary support when the first bite pad 1 and the second bite pad 6 are expanding, thereby improving the occlusal stability and preventing the bite pads from breaking.

[0038] The elastic frame 8 has a certain opening and closing effect, and can cooperate with the expansion work of the first tooth pad 1 and the second tooth pad 6 to change the size spacing, so that the staff can better perform the intubation work, and the intubation can also provide a certain limiting effect when inserting the tube to prevent movement or the pipe from falling off.

[0039] Embodiment 2: The tongue depressor mechanism 3 includes a movable shaft 9 and a tongue depressor 10 , and the movable shaft 9 is fixedly connected to the inner side of the first bite block 1 .

[0040] The tongue depressor 10 is connected to the outer side of the movable shaft 9.

[0041] As can be seen from the above, the tongue depressor 10 provided in the tongue depressor mechanism 3 performs the tongue depressing work through the movable shaft 9, thereby reducing the obstruction of vision and facilitating the staff to perform intubation work.

[0042] In the initial state of the dental pad, the tongue depressor 10 is covered on the inner side of the first dental pad 1 and the second dental pad 6 in the vertical direction through the movable shaft 9. When the dental pad is in use, the expansion distance between the first dental pad 1 and the second dental pad 6 is adjusted to a certain degree through the cooperation of the telescopic column 4 and the screw adjuster 5 provided in the adjustment mechanism 2. Then the pipe to be inserted is inserted along the inner side of the elastic frame 8. The tongue depressor 10 is pushed and pressed on the patient's tongue through the movable shaft 9, thereby avoiding the intubation work being blocked by the patient's tongue and the line of sight being blocked to a certain extent, so that the staff can better perform the intubation work.
