Detailed Description of the Invention

[0022] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Now, in conjunction with the drawings, the preferred embodiments of the present invention will be described in detail.

[0023] An embodiment of the present utility model provides a dental pad main body 11, as Figures 1 to 3 shown. The dental pad 1 includes a dental pad main body 11, which includes a sleeve pipe 111. The sleeve pipe 111 is a rigid pipe. The sleeve pipe 111 is provided with a through hole 1111 along the length direction. An opening 1112 communicating with the outer surface of the sleeve pipe 111 is provided on the hole wall of the through hole 1111. The opening 1112 extends along the length direction of the sleeve pipe 111. The opening 1112 is used for the air delivery pipe 2 to pass through the through hole 1111. A soft pad 112 is provided on the outer surface of the sleeve pipe 111.

[0024] Specifically, the dental pad main body 11 includes a sleeve pipe 111. The sleeve pipe 111 is provided with a through hole 1111 along the length direction. An opening 1112 communicating with the outer surface of the sleeve pipe 111 is provided on the hole wall of the through hole 1111. The opening 1112 extends along the length direction of the sleeve pipe 111. Through the opening 1112, the air delivery pipe 2 can pass through the through hole 1111 from the side wall of the sleeve pipe 111, so that the air delivery pipe 2 can be conveniently disassembled and assembled with the sleeve pipe 111, improving the convenience of using the dental pad 1. The opening 1112 also facilitates medical staff to adjust the position of the dental pad main body 11 on the air delivery pipe 2.

[0025] More specifically, to ensure the patency of the patient's airway, a structure for preventing airway blockage is often provided at the insertion end (the end inserted into the patient's airway) of the air delivery pipe 2. Therefore, the diameter of the insertion end of the air delivery pipe 2 is larger than the diameter of the middle part of the air delivery pipe 2. And the other end of the air delivery pipe 2 needs to be connected to a ventilator to deliver oxygen to the patient. Therefore, the insertion end of the air delivery pipe 2 cannot directly penetrate into the through hole 1111 of the sleeve pipe 111 from the orifice of the through hole 1111. The opening 1112 enables the air delivery pipe 2 to pass through the through hole 1111 from the side wall of the sleeve pipe 111, ensuring the smooth connection between the air delivery pipe 2 and the sleeve pipe 111, so that the dental pad 1 can be sleeved on the air delivery pipe 2, avoiding the patient biting the tongue or the air delivery pipe 2 when performing a biting action.

[0026] In addition, since the sleeve pipe 111 is a rigid pipe, and a soft pad 112 is sleeved on the outer surface of the sleeve pipe 111. Thus, when the patient's teeth bite the dental pad main body 11, the sleeve pipe 111 can ensure that the air delivery pipe 2 and the dental pad main body 11 will not deform when being bitten by the patient's teeth, thereby avoiding affecting the normal air delivery of the air delivery pipe 2. The soft pad 112 can increase the comfort when the teeth bite the dental pad main body 11, effectively reducing the risk of tooth loss or wear. Especially for the elderly with obvious tooth looseness, their teeth need more protection.

[0027] To enable those skilled in the art to better understand the solution of the present utility model, the following will combine the attached Figures 1 to 3 , and clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0028] Further, as a specific implementation manner in some embodiments of the present utility model, as Figure 3 shown, a hemmed portion 1121 is provided at the adjacent position of the soft pad 112 and the opening 1112. The air delivery pipe 2 includes an adjacent portion adjacent to the opening 1112, and the hemmed portion 1121 is snap-connected to the adjacent portion.

[0029] Specifically, a hemmed portion 1121 is provided at the adjacent position of the soft pad 112 and the opening 1112. The sleeve pipe 111 includes an adjacent portion adjacent to the opening 1112, and the hemmed portion 1121 is snap-connected to the adjacent portion. Thus, by snap-connecting the hemmed portion 1121 and the adjacent portion, the connection stability between the soft pad 112 and the sleeve pipe 111 can be increased, and when the teeth bite the soft pad 112 and the sleeve pipe 111, the soft pad 112 can be prevented from detaching from the sleeve pipe 111.

[0030] As a specific implementation manner in some embodiments of the present utility model, as Figure 3 shown, a retaining piece 12 is fixedly connected to the outer side wall of one end of the sleeve pipe 111. The retaining piece 12 includes two retaining portions 121 connected to the opposite sides of the outer side wall, and the two retaining portions 121 are used for abutting against both sides of the mouth.

[0031] Specifically, the outer side wall of one end of the sleeve pipe 111 is fixedly connected to the retaining piece 12. The retaining piece 12 includes two retaining portions 121 connected to the opposite sides of the outer side wall. Thus, during the use of the dental pad 1, the two retaining portions 121 can abut against both sides of the patient's mouth, and the dental pad 1 can be effectively prevented from slipping into the patient's oral cavity or airway, increasing the safety of the dental pad 1.

[0032] Preferably, the retaining piece 12 is approximately semicircular and is located on the side far from the opening 1112. The approximately semicircular retaining piece 12 can increase the abutting area between the retaining piece 12 and the patient's mouth and enhance the blocking effect of the retaining piece 12. Of course, the retaining piece 12 can also be a strip-shaped or column-shaped retaining strip located on the opposite sides of the outer side wall of the sleeve pipe 111. In addition, in order to ensure the comfort of the abutment between the retaining piece 12 and the patient's mouth, a soft cushion layer can be provided on the side of the retaining piece 12 that abuts against the patient's mouth to prevent burrs or small protrusions on the retaining piece 12 from stabbing the patient's mouth during abutment.

[0033] Further, as a specific implementation manner in some embodiments of the present utility model, as Figure 3 shown, the sleeve pipe 111 and the retaining piece 12 are integrally formed.

[0034] Specifically, integrally forming the sleeve 111 and the baffle 12 can ensure a more secure connection between the sleeve 111 and the baffle 12, reduce the possibility of loosening or detachment between the sleeve 111 and the baffle 12, enable the mouthguard 1 to provide more reliable performance during use, and also ensure the integrity and aesthetics of the appearance of the mouthguard 1. In addition, integrally forming the sleeve 111 and the baffle 12 can also simplify the manufacturing process and improve the production efficiency of the mouthguard 1.

[0035] Furthermore, as a specific implementation manner in some embodiments of the present utility model, as Figure 3 shown, the mouthguard 1 further includes a fixing band 13, and both ends of the fixing band 13 are respectively connected to the two stop portions 121.

[0036] Specifically, the mouthguard 1 further includes a fixing band 13, and both ends of the fixing band 13 are respectively connected to the two stop portions 121, and the fixing band 13 can be fixed at the back of the patient's head to cooperate with the two stop portions 121 that abut against both sides of the patient's mouth, so that the mouthguard 1 can be fixed in the patient's oral cavity to ensure that the mouthguard 1 does not come off the patient's oral cavity during use. It is worth mentioning that the fixing band 13 is an elastic band. Thus, the fixing band 13 can adapt to the head sizes of different patients.

[0037] Furthermore, as a specific implementation manner in some embodiments of the present utility model, as Figure 3 shown, threading holes 1211 are provided on both of the two stop portions 121, and both ends of the fixing band 13 are respectively fixed to the two threading holes 1211.

[0038] Specifically, threading holes 1211 are provided on both of the two stop portions 121, and both ends of the fixing band 13 can be conveniently connected to the stop portions 121 through the threading holes 1211. In addition, the length of the fixing band 13 can be adjusted through the threading holes 1211, or a new fixing band 13 can be replaced when the fixing band 13 is damaged.

[0039] As a specific implementation manner in some embodiments of the present utility model, as Figure 3 shown, the fixing band 13 is a flat band. Specifically, the fixing band 13 is a flat band, and the flat band can increase the contact area between the fixing band 13 and the patient's head, thereby reducing the pressure of the fixing band 13 on the patient's head to relieve the discomfort felt by the patient during wearing and improve the wearing comfort.

[0040] As Figure 1 shown, the present utility model also discloses a gas delivery assembly, and the gas delivery assembly includes a gas delivery pipe 2 and the mouthguard 1 as described above.

[0041] Specifically, the gas delivery assembly includes a gas delivery pipe 2 and the mouthguard 1 as described above. When treating symptoms such as respiratory arrest, airway obstruction, and hypoxia, the gas delivery pipe 2 can penetrate through the through hole 1111 of the mouthguard 1 from the opening 1112 of the mouthguard 1, so as to quickly assemble the gas delivery assembly to deliver gas to the patient.

[0042] Furthermore, as a specific implementation manner in some embodiments of the present invention, as Figure 3 shown, one end of the gas delivery pipe 2 is provided with a connection port 21 for connecting to a ventilator, and the other end of the gas delivery pipe 2 is provided with an air outlet 22, and an airbag 23 is provided on the side wall near the air outlet 22.

[0043] Specifically, one end of the gas delivery pipe 2 is provided with a connection port 21 which can be connected to a ventilator to deliver oxygen to the patient. The other end of the gas delivery pipe 2 is provided with an air outlet 22, and an airbag 23 is provided on the side wall near the air outlet 22. The airbag 23 can expand the patient's trachea to ensure unobstructed airway, ensure that the gas delivery pipe 2 can stably deliver oxygen, and ensure the safety of the patient.

[0044] Furthermore, as a specific implementation manner in some embodiments of the present invention, the diameter of the gas delivery pipe 2 is larger than the width of the opening 1112.

[0045] Specifically, the diameter of the gas delivery pipe 2 is larger than the width of the connection port 21, so that the gas delivery pipe 2 can be fixed in the through hole 1111 of the sleeve 111 to prevent the gas delivery pipe 2 from accidentally detaching. It can be understood that since the gas delivery pipe 2 is made of PVC material, the gas delivery pipe 2 has sufficient flexibility, so that the gas delivery pipe 2 can be inserted into the through hole 1111 from the opening 1112 and fixed in the through hole 1111 after being inserted.

[0046] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. For those skilled in the art, the technical solutions recorded in the above embodiments can be modified, or some of the technical features can be equivalently replaced; and all such modifications and replacements should fall within the protection scope of the appended claims of the present invention.
