Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a tooth pad for endoscopic examination. Background Art

[0002] During endoscopic examination, patients need to wear a dental guard to prevent them from biting the endoscope. Figure 1-2 As shown, it is made of hard plastic and mainly includes a baffle 11 and a bite tube 12; the baffle 11 is used to prevent the bite pad from being swallowed, and another function is to connect the belt through the openings on both sides of the baffle 11 to fix the bite pad. The sleeve is used to prevent the teeth from contacting the outer wall of the endoscope to protect the endoscope.

[0003] In order to protect the endoscope from being bitten by the patient, the entire tooth pad needs to be made of a harder material. However, in actual application, the endoscope will move back and forth in the bite tube 12. Since the material of the bite tube 12 is harder, when the endoscope contacts the bite tube 12, hard friction will be formed on the endoscope, which can easily damage the endoscope, and in the long run, the service life of the endoscope will be greatly reduced. Therefore, in order to alleviate the above problems, we propose a tooth pad for endoscopic examination. Utility Model Content

[0029] The utility model will be further described below in conjunction with the accompanying drawings.

[0030] Reference Figure 1-Figure 7 As shown, a bite pad for endoscopic examination of the present embodiment comprises a bite pad body and a protective member, wherein the bite pad body comprises a baffle 11, a bite tube 12 and a ring body 13, wherein the front end of the bite tube 12 is fixedly connected to the rear side of the baffle 11, the barrel cavity of the bite tube 12 passes through the baffle 11, the cross section of the ring body 13 is circular, the ring body 13 is fixedly connected to the rear end of the bite tube 12, the outer diameter of the ring body 13 is larger than the outer diameter of the bite tube 12, and the inner diameter of the ring body 13 is consistent with the inner diameter of the bite tube 12. Openings are also provided on the left and right sides of the baffle 11, and the openings are used to assemble a strap, and the patient can fix the bite pad body to the head through the strap. In the present embodiment, the bite pad body is made of hard plastic.

[0031] In this embodiment, the protective member includes an inner tube 21, a front edge 22 and a rear edge 23. The inner tube 21 is assembled in the bite tube 12. The front edge 22 is fixed to the front end of the inner tube 21 and extends forward from the bite tube 12. The portion of the front edge 22 extending forward from the bite tube 12 extends to the surroundings to cover the connection between the bite tube 12 and the baffle 11. The rear edge 23 is fixed to the rear end of the inner tube 21 and extends backward from the bite tube 12. The portion of the rear edge 23 extending backward from the bite tube 12 extends to the surroundings to cover the ring body 13. In this embodiment, the protective member is made of a flexible material, specifically one of silicone or rubber.

[0032] During actual use, the bite tube 12 is placed in the patient's mouth, and the baffle 11 is placed outside the mouth. The inner cavity of the inner tube 21 will serve as an endoscope channel for the endoscope to pass through. The inner tube 21 made of flexible material is located between the endoscope and the bite tube 12 to avoid hard contact between the endoscope and the bite tube 12. In this way, the endoscope can be prevented from being hard rubbed, thereby protecting the endoscope and extending its service life.

[0033] It should be emphasized that the endoscope will not have hard contact with the front end of the bite tube 12 and the baffle 11 because the front edge 22 covers the connection between the front end of the bite tube 12 and the baffle 11. Similarly, the rear edge 23 covers the ring body 13 at the rear end of the bite tube 12, so the endoscope will not have hard contact with the rear end of the bite tube 12.

[0034] It is worth mentioning that after the rear edge 23 covers the ring body 13 at the rear end of the bite tube 12, when the bite tube 12 enters the patient's mouth backward, the ring body 13 at the rear end of the bite tube 12 will not have hard contact with the patient's oral tissue. This can also protect the patient's oral tissue and improve the comfort of the dental pad when used.

[0035] In this embodiment, a first connector 131 is fixed to the front side of the ring body 13, and a first plug hole 231 is provided at the rear edge 23. There are four first connectors 131 and four first plug holes 231. The four first connectors 131 are evenly distributed in a circular array around the axis of the ring body 13, and the four first plug holes 231 are evenly distributed in a circular array around the axis of the inner cylinder 21. In this way, after the four first connectors 131 are respectively plugged into the four first plug holes 231, the inner cylinder 21 can be restricted from moving forward axially relative to the bite cylinder 12, so as to prevent the protective member from moving backward and separating from the bite pad body.

[0036] It is worth mentioning that the first connector 131 is inclined toward the axis of the bite tube 12 from the end away from the ring body 13 to the end close to the ring body 13. Such inclination can stabilize the plugging relationship between the first connector 131 and the first plug hole 231 to prevent the two from being separated from each other.

[0037] In this embodiment, the front side of the baffle 11 is fixedly connected with a second plug-in component 111, and the front edge 22 is provided with a second plug-in hole 221. There are four second plug-in components 111 and four second plug-in holes 221. The four second plug-in components 111 are evenly distributed in a circular array around the axis of the bite tube 12, and the four second plug-in holes 221 are evenly distributed in a circular array around the axis of the inner tube 21. In this way, after the four second plug-in components 111 are respectively plugged into the four second plug-in holes 221, the inner tube 21 can be restricted from moving axially backward relative to the bite tube 12, so as to prevent the protective component from moving forward and separating from the bite pad body.

[0038] It is worth mentioning that the second connector 111 is inclined toward the axis of the bite tube 12 from the end away from the baffle 11 to the end close to the baffle 11. Such inclination can stabilize the plugging relationship between the second connector 111 and the second plug hole 221 to prevent the two from being separated from each other.

[0039] In addition, in this embodiment, the inner tube 21 is an integral structure with the front edge 22 and the rear edge 23. This structure has high strength and is strong and durable. It can be produced by mold processing.

[0040] In summary, the utility model discloses a tooth pad for endoscopic examination, the inner side of the bite tube of the tooth pad is provided with a flexible structure, which can avoid hard friction between the endoscope and the bite tube during use, so as to protect the endoscope, thereby extending the service life of the endoscope.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
