Description

Technical Field

[0001] This utility model relates to the field of oral CT technology, specifically to an oral CT imaging auxiliary device. Background Technology

[0002] During oral CT scans, a bite block needs to be placed between the upper and lower teeth to separate them. However, traditional bite blocks cause inconvenience because they cannot adjust the spacing between teeth. Chinese patent CN216724593U discloses an oral CT imaging auxiliary device for oral medicine, including a lower dental plate with an adjustable upper dental plate rotatably connected to it. Both the upper and lower dental plates have arc-shaped grooves on their outer surfaces, with pads fixedly connected within these grooves. Two sets of relatively movable expansion plates are symmetrically distributed on the front sides of the upper and lower dental plates, moving synchronously with the upper dental plate. However, although this prior art can adjust the spacing between the upper and lower teeth during oral CT scans, its complex structure may create cleaning blind spots, making thorough cleaning and disinfection difficult and increasing the risk of cross-infection. Therefore, we propose a novel oral CT imaging auxiliary device that aims to simplify the structure and improve hygiene and safety while maintaining the adjustable function. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0021] In view of the problems existing in the prior art, the present invention provides an auxiliary device for oral CT imaging. The present invention will be described in detail below with reference to the accompanying drawings.

[0022] See Figures 1-4 As shown, the technical solution adopted in this specific embodiment is: an oral CT imaging auxiliary device, including an occlusal component 1, an air volume adjustment component 2, and a quick docking mechanism 3. The entire device is made of non-metallic material to avoid interference with CT imaging. The occlusal component 1 includes a base 11 and an air bladder 12 disposed on its upper and lower occlusal surfaces. The base 11 is integrally molded from medical-grade silicone. The cross-sectional thickness of the air bladder 12 has a biomimetic curved surface structure, with the greatest thickness in the middle and gradually thinning towards the edge along the center line of the occlusal surface, thus evenly distributing the occlusal pressure. The base 11 has an airway interface 13 communicating with the air bladder 12 on the side away from the occlusal end. The airway interface 13 is connected to the air volume adjustment component 2 through the quick docking mechanism 3.

[0023] It should be specifically noted that the gas volume regulating component 2 includes an air pump 21, an air guide pipe 22, and an air valve 221. One end of the air guide pipe 22 is connected to the air pump 21, and the other end is connected to the airway interface 13 via a quick-connect mechanism 3. The air valve 221 is located on the air guide pipe 22 and is used to regulate the gas flow rate and pressure. The air pump 21 is a hand-operated inflatable ball.

[0024] It should be specifically noted that the quick docking mechanism 3 includes a first connecting part 31 and a second connecting part 32. The first connecting part 31 is fixed to the end of the air duct 22 away from the air pump 21, and the second connecting part 32 is fixed to the airway interface 13. The first connecting part 31 includes an axially extending insertion cavity 311, and at least two circumferentially distributed elastic expansion grooves 312 are formed on its side wall. The elastic expansion grooves 312 extend from the opening end of the insertion cavity 311 to the inner wall to form an elastic snap-fit ​​structure 3112. After the first connecting part 31 and the second connecting part 32 are docked, a fluid channel 33 is formed that connects the air duct 22 and the airbag 12.

[0025] A sliding sleeve 313 is fitted around the outer periphery of the insertion cavity 311. A limiting ring 3131 is provided on the inner wall of the sliding sleeve 313. A buffer structure is provided between the insertion cavity 311 and the sliding sleeve 313. The buffer structure includes an annular receiving groove 3111 and a built-in elastic element 314. The annular receiving groove 3111 is opened on the outer wall of the insertion cavity 311. The elastic element 314 is a helical spring. The two ends of the helical spring abut against the bottom of the annular receiving groove 3111 and the limiting ring 3131, respectively.

[0026] The second connecting part 32 has a tapered guide part 322 at the insertion end and an annular locking groove 321 on the outer wall. The two side walls of the annular locking groove 321 are provided with outwardly expanding guide slopes 3211. The inclination angle of the guide slopes 3211 is 15°-30°.

[0027] The inner wall of the insertion cavity 311 is provided with an arc-shaped protrusion buckle 3112. When the second connecting part 32 is inserted into the first connecting part 31, the conical guide part 322 guides the insertion, and the elastic expansion groove 312 is compressed and deformed until the buckle 3112 is embedded in the annular locking groove 321, achieving quick locking. An annular seal 34 is provided at the joint. The annular seal 34 is made of medical-grade silicone to ensure airtightness.

[0028] When both the upper and lower interlocking surfaces of the substrate 11 are provided with airbags 12, the second connecting part 32 is a Y-shaped diversion component, with its main channel 323 connected to the air guide tube 22 and two branch channels 324 respectively connected to the upper and lower airbags 12 to achieve synchronous inflation.

[0029] Working principle: After the patient bites onto the matrix 11, the air pump 21 is activated. Gas enters the air bladder 12 through the air tube 22 and the quick-connect mechanism 3. The inflation volume is adjusted by the air valve 221 to control the inflation height of the air bladder 12, thereby adjusting the distance between the upper and lower teeth to meet the needs of different patients. After inflation, the air valve 221 is closed to maintain pressure. After the examination, pressing the sliding sleeve 313 releases the buckle 3112, quickly separating the first connecting part 31 from the second connecting part 32, allowing the occlusal component 1 to be detached from the air volume adjustment component 2 for separate disinfection. This utility model has a simple structure, reduces cleaning dead spots, achieves adaptive adjustment of occlusal force through the air bladder 12, and achieves reliable connection and rapid separation of the air path with the quick-connect mechanism 3, facilitating local cleaning and disinfection and reducing the risk of cross-infection.
