[0026] Before introducing the technical solutions of the present utility model, it is necessary to elaborate on the creation background of the invention of the present utility model. As is commonly known, tracheal intubation is often used in combination with a dental pad. Currently, the dental pads used clinically are made of hard materials and come in different sizes. Small-sized dental pads are not easy to fix and are easily spat out, and there is a relatively high risk of biting the tube and blocking the airway; large-sized dental pads even fill the entire oral cavity, affecting the patient's comfort and easily causing pressure injuries to the lips. The comfort and safety of patients are facing challenges. In order to overcome the above technical problems of the prior art, the present utility model aims to provide a dental pad for tracheal intubation.

[0027] An exemplary embodiment of the present utility model provides a dental pad for tracheal intubation, which is used in cooperation with a tracheal intubation tube and a suction tube. Please refer to Figure 1 and Figure 2, which includes a dental pad body 1. Inside the dental pad body 1, there is a first through groove 11 for fixing an endotracheal tube and a second through groove 12 for inserting a suction tube. It should be noted that traditional endotracheal tubes are fixed to the dental pad with medical tape. However, due to the oral and pharyngeal secretions, the medical tape is likely to lose its adhesiveness. Therefore, the dental pad body 1 of the present utility model is provided with a first through groove 11 inside to enable the endotracheal tube to pass through and be fixed. At the same time, the design of the second through groove 12 is to reserve a suction channel for the suction tube to aspirate the oral and pharyngeal secretions, reducing the discomfort of the patient. On the side of the dental pad body 1, there is a lip baffle 2. The lip baffle 2 is configured with two groups of elastic bands 21 (only one side is shown in the figure) that can be pasted together. Below the lip baffle 2 on the side of the dental pad body 1, there is an airbag 3 whose size can be adjusted. There is a gap between the lip baffle 2 and the airbag 3 for the patient's teeth to bite. Among them, the bottom end of the dental pad body 1 is provided with an arc portion 14 that provides a fitting position for the patient's tongue.

[0028] It should be understood that when in use, first put the main body of the dental pad into the patient's oral cavity. The patient's teeth bite at the gap between the lip baffle 2 and the airbag 3, and the two groups of elastic bands 21 are passed around the patient's head from the left and right sides and pasted together to fix the position of the main body of the dental pad and prevent the main body of the dental pad from shifting during use. Further, start inflating the airbag 3 and control the inflation degree of the airbag 3 according to the patient's oral physiological structure to fit the inside of the patient's oral cavity. While effectively preventing the main body of the dental pad from falling off, it can also reduce the discomfort caused by biting without the patient's subjective biting. As a preferred technical solution, the value of the designed gap is 1 cm - 2 cm to adapt to the oral physiological structures of different patients.

[0029] Further, please refer to Figure 1 and Figure 2 , the end of the elastic band 21 is configured with a magic tape 211. After the two groups of elastic bands 21 are stretched, they can surround the patient's head for one week and be fixed by the magic tape 211. With the design of configuring the magic tape 211, there is no need to use a binding band for fixation, which is convenient for medical staff to fix and remove this dental pad.

[0030] Further, at least the surface of the lip baffle 2 is made of medical silicone material. The lip baffle 2 made of silicone material has a soft surface, which can improve the wearing comfort.

[0031] In some embodiments, the lip baffle 2 is arranged in a circular ring shape around the side of the dental pad body 1. The circular lip baffle 2 effectively increases the fitting area between the lip baffle 2 and the patient's lips compared with the traditional left and right independent baffles, avoiding the lip baffle 2 falling off due to displacement when fixing the dental pad body 1. As shown in Figure 1 and Figure 2 , two groups of through holes 22 are provided at opposite ends of the lip baffle 2. These through holes 22 are used for the elastic bands 21 to pass through and be fixed.

[0032] As a preferred technical solution, please refer to Figure 1 and Figure 2 , a gas charging pipe 31 and a gas charging valve 32 connected to the gas charging pipe 31 are arranged at the top end of the airbag 3. Specifically, the airbag 3 is communicated with the gas charging pipe 31, and one end of the gas charging pipe 31 is provided with a gas charging valve 32 for externally connecting a gas supply device. During operation, the gas charging valve 32 conveys gas into the airbag 3 through the gas charging pipe 31, and the airbag 3 expands as needed; when it is necessary to take out the dental pad body 1, the airbag 3 is deflated through the gas charging valve 32, and the operation is simple. It should be noted that, as a preferred technical solution, the airbag can cover the area between the gap 13 and the arc-shaped part 14 to reduce the discomfort caused by the contact between the inside of the patient's oral cavity and the dental pad body 1 to a greater extent. In addition, a reserved groove for inserting the gas charging pipe 31 is also formed on the lip baffle 2 so that each structure does not interfere with each other.

[0033] As a preferred technical solution, after being inflated, the airbag 3 is in a gradually reduced diameter shape to conform to the physiological structure of the human oral cavity. Specifically, as Figure 2 shown, Figure 2 is a schematic structural diagram of a dental pad for tracheal intubation with an inflated airbag 3 provided by some embodiments. The end of the inflated airbag 3 gradually reduces in diameter, presenting an inverted pear shape as a whole, so as to conform to the physiological structure of the human oral cavity and reduce the extrusion of the pharynx by the inflated airbag 3.

[0034] As a preferred technical solution, the airbag is made of a skin-friendly and bite-proof material to reduce the discomfort of the patient.

[0035] In summary, the dental pad of the present utility model has the following technical advantages: 1. It can clamp the tracheal intubation to improve the stability of the tracheal intubation and the dental pad, and at the same time can also clamp the suction tube to aspirate the secretions in the oropharynx; 2. By providing an oral airbag, the size of this airbag can be adjusted according to the size of the patient's oral cavity, so that the dental pad fits better with the patient's oral dental bed, making the patient's wearing experience more comfortable; 3. This dental pad is fixed as a whole through an elastic band, avoiding the defect that the traditional fixation by medical tape is easily contaminated and invalidated by the patient's oral secretions. Therefore, compared with the existing dental pad technology, the dental pad for tracheal intubation provided by the present utility model has obvious technical advantages.

[0036] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model.
