Description

Technical Field

[0001] The utility model belongs to the technical field of oral drainage, and in particular relates to a dental pad for continuous drainage of oral secretions. Background Art

[0002] Negative pressure drainage equipment is a medical device that guides pus, blood, and liquid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. At present, in the process of oral treatment for patients by dental medical staff, medical staff usually use cleaning fluid and medicine to clean the patient's oral area. The patient keeps his mouth open for a long time, and his mouth will secrete a large amount of saliva. If these mixed liquids are not handled in time, they will flow out from the corners of the patient's mouth, making the patient need to get up repeatedly to spit out the waste liquid. This process greatly reduces work efficiency. Therefore, in the dental department, negative pressure drainage equipment will be combined with drainage dental pads to continuously drain the patient's oral secretions. However, the existing drainage dental pads are relatively simple in function, and it is not convenient for medical staff to observe the patient's mouth through the drainage dental pads. Therefore, in response to this problem, we proposed a dental pad for continuous drainage of oral secretions. Utility Model Content

DETAILED DESCRIPTION

[0025] The utility model will be further described below in conjunction with the accompanying drawings.

[0026] Reference Figure 1-Figure 6 As shown, a dental pad for continuous drainage of oral secretions in this embodiment includes a tube 1, a drainage head 2, a sealing member 3 and a bite pad 4.

[0027] In this embodiment, the pipe fitting 1 includes a pipe body 11 and a connecting pipe 13. The connecting pipe 13 is fixedly connected to the rear end of the pipe body 11, and is used to connect with the drainage tube of the negative pressure drainage device. The pipe body 11 is in the shape of a rectangular parallelepiped, which is convenient for patients to hold and for medical staff to hold. The upper and lower sides of the front end of the pipe body 11 also extend forward to form a rotating seat 12. Both rotating seats 12 are provided with an axial hole 122. The axial hole 122 is provided for rotating and assembling the drainage head 2. A first assembly groove 111 is also provided at the front end of the pipe body 11. In addition, a second assembly groove 121 connected to the first assembly groove 111 is provided on the opposite side of the two rotating seats 12. The first assembly groove 111 cooperates with the two second assembly grooves 121 for assembling the seal 3.

[0028] It is worth mentioning that the tube body 11, the connecting tube 13 and the rotating seat 12 of the present embodiment are an integrated structure, which has good connection strength and can be formed by injection molding.

[0029] In this embodiment, the drainage head 2 includes a circular plate 21, a lens 22 and an axial protrusion 23. The number of the axial protrusions 23 is two. The two axial protrusions 23 are respectively fixed to the two axial ends of the circular plate 21 and are coaxial with the circular plate 21. The two axial protrusions 23 are respectively rotatably assembled in the two axial holes 122, so that the circular plate 21 is rotatably connected between the two rotating seats 12. In addition, lens assembly grooves 212 are provided at both axial ends of the circular plate 21. Accordingly, the number of the lenses 22 is two, and the two lenses 22 are respectively fixed in the two lens assembly grooves 212. Ten drainage holes 211 are provided on the side of the circular plate 21, and the ten drainage holes 211 are connected to each other near one end of the axis of the circular plate 21.

[0030] In this embodiment, the seal 3 is arranged between the circular plate 21 and the tube body 11 to seal the gap between the circular plate 21 and the tube body 11. The seal 3 is provided with a connecting groove 31, the rear end of which is used to connect to the inner cavity of the tube body 11 and the front end of which is used to connect to the drainage hole 211 opposite to the inner cavity of the tube body 11. Specifically, the seal 3 includes an annular rubber pad 32 assembled in the first assembly groove 111, the front end of the annular rubber pad 32 is sealed against the side wall of the circular plate 21, the rear end of the annular rubber pad 32 is abutted against the bottom of the first assembly groove 111, and the connecting groove 31 is arranged in the middle of the annular rubber pad 32, so that the gap between the circular plate 21 and the seal 3 can be sealed, so that the fluid can flow efficiently between the tube body 11 and the drainage hole 211, and the drainage negative pressure can be effectively formed in the drainage hole 211.

[0031] It is worth mentioning that among the 10 drainage holes 211 of this embodiment, the distance between any two adjacent drainage holes 211 is smaller than the width of the connecting groove 31, so that the drainage holes 211 can be connected to the inner cavity of the tube body 11 when the circular plate 21 rotates to any angle.

[0032] In this embodiment, the seal 3 further includes two rubber strips 33, which are respectively assembled in the two first assembly grooves 111 and connected to the annular rubber pad 32. The opposite sides of the two rubber strips 33 are respectively elastically abutted against the two lenses 22. The rubber strips 33 are arranged in this way to wipe the lenses 22 when the circular plate 21 rotates, so as to wipe off the liquid on the surface of the lenses 22, so that the lenses 22 are rotated out of the two rotating seats 12 and are in a clean state, so that medical staff can use the lenses 22.

[0033] It is worth mentioning that the rubber strip 33 can also form resistance for the rotation of the circular plate 21, so that the circular plate 21 is not easy to rotate at will.

[0034] In this embodiment, the annular rubber pad 32 and the two rubber strips 33 are an integrally formed structure, and the sealing member 3 is made of medical silica gel or medical rubber.

[0035] In this embodiment, the bite pad 4 is a cylindrical structure, which is sleeved on the outside of the tube body 11 and fixedly connected to the tube body 11. The bite pad 4 is made of medical silicone or medical rubber. Such a configuration can enhance the touch of the outside of the tube body 11 and increase the friction coefficient to facilitate the patient's bite.

[0036] When in use, the connecting tube 13 of the pipe fitting 1 is connected to the negative pressure drainage tube of the negative pressure drainage device. After starting the negative pressure drainage device, the medical staff can hold the pipe fitting 1 and place the drainage head 2 in the patient's mouth to drain the saliva and other liquids in the patient's mouth through the drainage hole 211. In addition, the patient can bite the pipe fitting 1 with his teeth, so that the drainage tooth pad is in the patient's mouth for continuous drainage.

[0037] When observing the affected part or wound in the patient's oral cavity, if the affected part is located on the upper wall of the oral cavity, the medical staff can hold the tube 1 to control the movement of the lens 22, so that the upper wall of the patient's oral cavity can be observed through the reflection of the lens 22, so that the medical staff can timely understand the status of the patient's affected part. It is worth mentioning that when using the lens 22, the medical staff can control the side of the circular plate 21 to abut against the patient's teeth, and then push the tube 1 to control the circular plate 21 to roll to clean the lens 22 on the end face of the circular plate 21, so as to remove the liquid on the lens 22 and keep the lens 22 clear, so that the medical staff can clearly observe the affected part.

[0038] In summary, the utility model discloses a dental pad for continuous drainage of oral secretions. The dental pad can be held by medical staff to drain the liquid in the patient's mouth, or the patient can bite it in the mouth to continuously drain the liquid in the mouth. In addition, the dental pad also has a lens, which can facilitate medical staff to observe the upper wall of the patient's mouth.
