Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an inflatable dental pad. Background Technology

[0002] A dental splint is a medical device used to protect the mouth and teeth. During oral surgery or examinations, a dental splint is used to keep the patient's mouth open, preventing unintended biting and facilitating the insertion of surgical instruments or examination equipment. However, currently used dental splints are relatively hard and large, making insertion difficult, especially for the elderly, young children, or those with impaired consciousness, who may not be able to actively cooperate by opening their mouths to the predetermined extent, thus making it difficult to place the dental splint inside. Utility Model Content

[0003] The purpose of this invention is to provide an inflatable dental pad to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: an inflatable mouthguard, comprising: a first airbag with an inner hole structure formed in the middle with both ends penetrating through it, making the cross-section of the first airbag annular; the first airbag is connected to an inflation hose for deflating and inflating; two support plates, respectively installed inside the first airbag, and the two support plates are respectively located on two opposite sidewalls of the inner hole structure; a plurality of support rings, arranged side by side in the inner hole structure, the two sides of the support rings being movably connected to two opposite sidewalls of the inner hole structure; when the first airbag is deflated, the first airbag is in a flat state, causing the two support plates to move closer to each other, causing the plurality of support plates to swing and be in a collapsed state; when the first airbag is inflated, the first airbag is in an inflated state, causing the two support plates to move away from each other, causing the plurality of support plates to swing and be in an upright state to support the two support plates.

[0005] The technical solution has at least the following beneficial effects: when the first airbag is deflated, the two support plates move closer to each other and flatten the whole, so that the inflatable mouthpiece can be easily and conveniently inserted into the mouth of a patient who has difficulty opening his mouth. After the first airbag is inflated through the inflation tube, the first airbag separates the two support plates and expands the whole into a three-dimensional shape, so that the inner hole structure of the first airbag forms a channel in the patient's mouth that is easy for the instrument to be inserted.

[0006] As a further improvement to the above technical solution, the support ring is an elliptical ring.

[0007] As a further improvement to the above technical solution, the cross-section of the support ring is elliptical, which makes the support ring provide more stable support for the support plate.

[0008] As a further improvement to the above technical solution, the ends of both support pieces and the first airbag are bent in the same direction, allowing the bent portions to reach the pharynx.

[0009] As a further improvement to the above technical solution, an inner tube is installed on the outer wall of the inner hole structure, and both ends of the inner tube extend to the two ends of the first airbag. Oxygen delivery or suctioning can be performed through the inner tube.

[0010] As a further improvement to the above technical solution, the cross-sectional area of ​​the front section of the first airbag is larger than that of the rear section. This makes the front section of the first airbag more stably confined in the patient's mouth.

[0011] As a further improvement to the above technical solution, protruding second air bladders are provided on both sides of the first air bladder at the end with the smaller cross-sectional area, and the second air bladders are connected to the first air bladder. The second air bladders further restrict movement inside the patient, improving the stability of the inflatable dental splint.

[0012] As a further improvement to the above technical solution, the opposite sides of the two second airbags are arc surfaces.

[0013] As a further improvement to the above technical solution, the cross-section of the first airbag is square.

[0014] As a further improvement to the above technical solution, the cross-section of the inner hole structure is square. Attached Figure Description

[0027] Reference Figure 1-6The inflatable mouthguard includes a first airbag 100, two support plates 200, and multiple support rings 300. The first airbag 100 has an inner hole structure 110 in its center, with both ends of the inner hole structure 110 penetrating through it. Both the cross-section of the first airbag 100 and the cross-section of the inner hole structure 110 are square, resulting in a ring-shaped cross-section of the first airbag 100. The first airbag 100 is divided into a front section and a rear section, with the length and width of the front section's cross-section being larger than those of the rear section. An inflation hose 120 is connected to the front section of the first airbag 100, and the inflation hose 120 has a valve, allowing for inflation or deflation of the first airbag 100.

[0028] A second airbag 500 is provided on both sides of the first airbag 100, and the second airbags 500 are connected to the first airbag 100. The two second airbags 500 protrude in opposite directions, and the opposite side of the two second airbags 500 forms an arc surface 510. The second airbags 500 can be confined to the sides of the patient's mouth, thereby improving the overall stability of the inflatable mouthpiece.

[0029] The support piece 200 is made of rigid silicone. Both support pieces 200 are installed inside the first airbag 100, and both support pieces 200 are fixed to the two opposite inner sidewalls of the inner hole structure 110 by adhesive.

[0030] In this embodiment, six support rings 300 are provided. The support rings 300 are generally elliptical ring structures, and their cross-sections are also elliptical. The six support rings 300 are arranged side-by-side in the inner hole structure 110, with their two sides along the minor axis respectively movably disposed on two opposite outer walls of the inner hole structure 110. It can be understood that the support rings 300 are positioned between two support pieces 200, and the support rings 300 provide support for the two support pieces 200.

[0031] When the air in the first airbag 100 is completely or almost completely removed through the inflation hose 120, the first airbag 100 is in a flattened state. The strong pressure presses the two support plates 200 close together and makes them stick together. The multiple support rings 300 swing in the same direction and are in a folded-down state (see reference). Figure 4This design allows the inflatable mouthguard to be inserted into the mouth of a patient who has difficulty opening their mouth wide, as the entire structure is thin. The first air bladder 100 is then slowly inflated via the air hose 120, restoring its three-dimensional structure. Simultaneously, multiple support rings 300 swing in the opposite direction, rising from a folded position to an upright position, thus supporting the two support plates 200. This enhances the overall support capacity of the inflatable mouthguard, ensuring that surgical or diagnostic instruments can be smoothly and safely inserted through the inner hole structure 110.

[0032] In addition, because the two support pieces 200 are relatively misaligned, the end of the inflatable dental pad is shaped like an eagle's beak when the air is deflated, which makes it easier to insert it into the patient's mouth.

[0033] The support ring 300 is flexibly connected to the inner hole structure 110, allowing the support ring 300 to swing relative to the outer wall of the inner hole structure 110 at a predetermined angle. (Refer to...) Figure 5-6 Specifically, a connecting fabric is bonded to the inner wall of the inner hole structure 110, and the support ring 300 is fixed to the connecting fabric. An elastic segment, not connected to the inner wall of the inner hole structure 110, is formed on the side of the connecting fabric opposite to the direction in which the support ring 300 needs to swing. When the support ring 300 is lowered, the elastic segment is stretched; when the support ring 300 is upright, the elastic force of the elastic segment can keep the support ring 300 upright, thereby improving the support stability of the support ring 300.

[0034] In other embodiments, the support ring 300 can also be directly bonded and fixed to the inner wall of the first airbag 100, utilizing the flexible material properties of the first airbag 100 to achieve the swinging process of the support ring 300. In other embodiments, the support ring 300 can also be rotatably connected to the outer wall of the inner hole structure 110 via a shaft.

[0035] Reference Figure 1-4 Furthermore, the ends of the inflatable mouthguard are bent, meaning the ends of the two support plates 200 and the end of the first air bladder 100 are all bent in the same direction, allowing the bent portion of the inflatable mouthguard to enter the patient's pharynx. An inner tube 400 is installed on the side wall of the inner bore structure 110, with both ends of the inner tube 400 flush with the corresponding ends of the first air bladder 100. A connection port 410 communicating with the inner tube 400 is installed on the outside of the first air bladder 100. The connection port 410 can be used to connect an oxygen delivery tube or a suction tube, allowing oxygen delivery or suctioning operations to be performed through the connection port 410 and the inner tube 400.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
