Description

Technical Field

[0001] The utility model relates to a dental pad, in particular to a protective dental pad for tracheal intubation. Background Art

[0002] Tracheal intubation is a common, rapid and effective way to establish an artificial airway specifically for treating critically ill patients, and a dental pad is an essential accessory for tracheal intubation, which is used to ensure the fixation of the intubation and the patency of the airway.

[0003] At present, many types of dental pads have emerged. Figure 1 Fig. shows the structure of a common existing dental pad, which includes a tube body 51 as the main body of the dental pad. The tube body 51 has a through hole 510 for inserting an intubation tube. One end of the tube body 51 is provided with a retaining piece 52, and the retaining piece 52 is provided with a perforation for tying and fixing an inch belt 53. This existing dental pad can well assist the smooth progress of tracheal intubation, but there are still the following disadvantages: First, the size of the dental pad tube body 51 is fixed, and the difference in the size of the patient's oral cavity is not considered, resulting in low comfort. For patients with a larger oral cavity, the dental pad is likely to fall off during use. For patients with a smaller oral cavity, the operation of inserting the dental pad into the oral cavity is very difficult. Especially for patients with blurred consciousness after anesthesia, it is even more difficult to insert the dental pad. Second, the cylindrical structure of the tube body 51 cannot ensure the stable fixation of the dental pad in the oral cavity. Third, when the patient is in the prone position for intubation and ventilation, the use of the dental pad is likely to cause the patient's tongue body to protrude, which not only increases the risk of tongue body injury but also hinders other oral operations.

[0004] Therefore, it can be seen that designing a dental pad that can overcome the above disadvantages is an urgent problem to be solved at present. Content of the Utility Model

[0005] The purpose of the utility model is to provide a protective dental pad for tracheal intubation, which can be stably fixed in the oral cavity, has high comfort, effectively prevents the patient's tongue body from protruding, is convenient for placing the intubation tube, is easy to replace, and is suitable for popularization.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A protective dental pad for tracheal intubation includes a cylindrical handle portion. On both sides of the top of the handle portion, a sheet-shaped head is respectively extended. The head and the handle portion form a T shape. The head is provided with a perforation. On both sides of the lower part of the handle portion, an elastically deformable occlusal pad is respectively provided. On both sides of the middle part of the handle portion, a sheet-shaped lip guard pad is respectively provided. Each lip guard pad is located between the head and the occlusal pad on the same side of the handle portion as it. Among them, the handle portion is provided with a through-opening along its own length direction.

[0008] The advantages of the utility model are:

[0009] The dental pad of the present utility model can meet the needs of patients with different oral sizes through the design of an elastic occlusal pad, has high comfort, is not easily detached from the oral cavity, ensures the stable fixation of the dental pad in the oral cavity, and is convenient to insert. In addition, the dental pad of the present utility model can better prevent the patient's tongue from protruding through the design of the lip guard pad. Especially when the patient is in the prone position for endotracheal intubation and ventilation, the risk of tongue injury is reduced, and the obstruction during other oral operations is reduced. Moreover, through the design of the through-opening, the convenience of endotracheal intubation placement is improved, and the quick replacement of the dental pad can be realized. Description of the Drawings

[0010] Figure 1 is a schematic structural view of an existing dental pad.

[0011] Figure 2 is a schematic structural view of the protective dental pad for endotracheal intubation of the present utility model. Detailed Description of the Invention

[0012] As Figure 2 shown, the protective dental pad for endotracheal intubation of the present utility model includes a cylindrical handle portion 11. The handle portion 11 has a through-hole for inserting an endotracheal tube. On both sides of the top of the handle portion 11, a sheet-like head portion 12 is respectively extended. The head portion 12 and the handle portion 11 form a T shape. A perforation 13 is provided on the head portion 12. On both sides of the lower part of the handle portion 11, an elastically deformable occlusal pad 20 is respectively provided. On both sides of the middle part of the handle portion 11, a sheet-like lip guard pad 30 is respectively provided. Each lip guard pad 30 is located between the head portion 12 and the occlusal pad 20 on the same side of the handle portion 11. That is, on both sides of the handle portion 11, a set of components is respectively provided. In each set of components, the head portion 12, the lip guard pad 30, and the occlusal pad 20 are arranged in sequence from top to bottom on the handle portion 11. Among them, the handle portion 11 is provided with a through-opening 110 along its own length direction.

[0013] As Figure 2 shown, the occlusal pad 20 is in a U shape and is bent in a direction perpendicular to the length direction of the handle portion 11. The protruding part of the occlusal pad 20 is fixed to the outer surface of the handle portion 11.

[0014] As Figure 2 shown, the lip guard pad 30 is parallel or substantially parallel to the head portion 12.

[0015] In actual design, anti-slip lines (not shown in the figure) are uniformly distributed on the inner wall of the through-hole of the handle portion 11. The anti-slip lines are used to prevent the endotracheal tube placed in the through-hole of the handle portion 11 from slipping.

[0016] As Figure 2, the perforation 13 includes a semi-circular hole 131 and a strip-shaped hole 132 that communicate with each other. The strip-shaped hole 132 is arranged near the suspended end of the head 12. The semi-circular hole 131 is used for the insertion of medical 3M adhesive tapes and inch tapes, and the strip-shaped hole 132 is used to keep them flat after the medical 3M adhesive tapes and inch tapes are inserted.

[0017] In actual design, such as Figure 2 , the opening 110 is located between two occlusal pads 20 on both sides of the handle 11. Among them, the opening 110 is one-eighth of the circumferential length of the handle 11. As long as it meets the requirements of allowing the intubation tube to be inserted smoothly and preventing the intubation tube from slipping out by itself, usually, the size of the opening 110 is slightly smaller than the diameter of the intubation tube.

[0018] In actual design, a plurality of small holes are evenly distributed on the occlusal pad 20, which are used to absorb the secretions in the patient's oral cavity and prevent the breeding of bacteria caused by oral fluid accumulation. And, the occlusal pad 20 should be treated with antibacterial agents to inhibit the reproduction of surface bacteria and reduce the risk of oral infection.

[0019] In actual design, the surface of the lip guard 30 facing the occlusal pad 20 is a concave surface matching the shape of the lips and is provided with irregular concave and convex stripes, which are used to closely fit the patient's lips. In addition, the lip guard 30 usually should extend beyond the occlusal pad 20, and the edge of the lip guard 30 should be smoothed to greatly protect the patient's lips from excessive squeezing and abrasion.

[0020] In actual production, the handle 11 and the head 12 can be integrally formed.

[0021] Furthermore, the handle 11 and the head 12 are made of amorphous medical plastics, which have the characteristics of high ductility, strong compressive and tensile strength, and good wear and corrosion resistance. They can cooperate with the anti-slip pattern and medical 3M adhesive tape to fix the intubation tube without falling off.

[0022] Furthermore, the occlusal pad 20 is made of intelligent gel material, which has absorbency and slow-release properties, and can adapt to different oral structures of different patients, that is, it can adapt to the situations of different patients with different tooth shapes biting with different forces, improving the comfort of the patients and the adaptability of the dental pad. When in use, the arched concave area of the occlusal pad 20 can naturally fit with the patient's dental structure.

[0023] Furthermore, the lip guard 30 is made of silicone sponge or polyurethane sponge, which has high resilience, can adapt to lips of different sizes and shapes, and has good antibacterial and water absorption properties, can keep the lip part dry and inhibit the growth of bacteria.

[0024] During use, first check and clean the patient's oral cavity and cheek area, and place the tracheal intubation in the center of the patient's oral cavity. Then align the intubation, align the opening 110 of the handle 11 with the intubation and press it, so that the entire dental pad of the present utility model is completely sleeved outside the intubation. Next, make the two side occlusal pads 20 face the patient's upper and lower lips directly, and then move the dental pad of the present utility model along the intubation, so that the two side occlusal pads 20 are moved to the occlusal surfaces of the patient's upper and lower front teeth and canine teeth. After the occlusal pad 20 is moved in place, pinch the handle 11 with fingers to squeeze, so that the anti-slip lines on the inner wall of the hole of the handle 11 are in full contact with the intubation, and the frictional force between the two can prevent the relative displacement between the intubation and the dental pad of the present utility model. Then let the patient fully bite the dental pad of the present utility model, that is, make the occlusal pad 20 face the occlusal surfaces of the patient's upper and lower front teeth and canine teeth directly, and make the lips closely adhere to the lip guard pad 30. Thus, the positioning of the dental pad of the present utility model is completed. Then apply the medical hydrocolloid dressing to both sides of the patient's cheeks, pass the medical 3M adhesive tape through the perforation 13 of the head 12 and wind it around the intubation for fixation, and then stick the medical 3M adhesive tape on the dressing for fixation, so as to complete the fixation of the intubation and the dental pad of the present utility model. Finally, pass the inch belt through the perforation 13 of the head 12 and tie a knot around the back of the neck for fixation.

[0025] The present utility model has the following beneficial effects:

[0026] The dental pad of the present utility model can be seamlessly joined with the front teeth and canine teeth of the oral cavity by means of the occlusal pad. Due to the elastic deformation of the occlusal pad, the dental pad of the present utility model can adapt to different oral environments. The design of the occlusal pad plus the anti-slip lines further ensures the stable fixation of the dental pad in the oral cavity, reduces the discomfort caused to the patient by the relative displacement of the intubation, realizes the closure of the oral cavity, and prevents external bacteria from invading the patient's oral cavity.

[0027] The dental pad of the present utility model is made of a material with little irritation to the patient's lips, can be used for a long time, and has a strong absorption and inhibition effect on the growth of bacteria in the oral cavity, reducing the risk of oral infection of the patient.

[0028] The above is the preferred embodiment of the present utility model and the technical principles applied. For those skilled in the art, any obvious changes such as equivalent transformation and simple replacement based on the technical solution of the present utility model without departing from the spirit and scope of the present utility model shall fall within the protection scope of the present utility model.
