DETAILED DESCRIPTION

[0019] Hereinafter, the concept of the utility model will be further described according to specific embodiments. However, the specific embodiments listed are only for illustrative purposes and are not intended to limit the scope of the utility model. Those skilled in the art will recognize that the specific features in any of the following embodiments can be used in any other embodiment as long as it does not deviate from the utility model concept described herein.

[0020] refer to Figure 1 and Figure 2 The utility model provides a medical toothbrush. The bristles 6 are mounted on the first surface 11 of the brush head 1. A sponge layer 3 is wrapped on at least one surface of the brush head other than the first surface 11 where the bristles 6 are located (for example, only on the back surface or all surfaces except the first surface 11). The sponge layer 3 can play the role of wiping the oral cavity and absorbing the secretion liquid of the oral affected area. On at least one surface other than the first surface 11 of the brush head 1, the sponge layer 3 (for example, patterned) is a concave-convex structure 31 arranged in an array. The contact friction between the sponge layer 3 and the inner surface of the oral cavity or the affected area is increased by the concave-convex structure 31 arranged in an array, and the depression 312 in the sponge layer 3 can accommodate foreign matter in the oral cavity, thereby effectively taking out the foreign matter in the oral cavity.

[0021] Continue to refer Figure 1 and Figure 2 The brush head 1 is hollow, and the medical toothbrush also includes a hollow brush handle 2 connected to the brush head 1, and an injection tube 4 and a negative pressure suction tube 5 arranged in the inner cavity of the brush head 1 and the brush handle 2. In order to meet the needs of oral drug flushing, especially Chinese medicine flushing treatment, the brush head 1 is also provided with an injection hole 12 and a suction hole 13. The injection hole 12 passes through the first surface 11 of the brush head 1 where the bristles 6 are located. The injection hole 12 can be opened between the bristles 6, or hollow bristles can be arranged to be connected to the injection hole 12. The injection hole 12 is connected to the injection tube 4. The injection tube 4 can be connected to the injection tube 4 through a syringe to manually control the injection intermittently; or the injection tube 4 can be connected to the infusion set for continuous injection. The injection tube 4 can also be provided with an additional flow regulating device. The suction hole 13 passes through the depression 312 of the concave-convex structure 31. The suction hole 13 is connected to the negative pressure suction tube 5. The negative pressure suction tube 5 can be connected to a negative pressure connector or a negative pressure source to suck out the liquid in the oral cavity.

[0022] Under the condition of oral closure, the injection tube 4, the injection hole 12, the oral cavity, the suction hole 13 and the negative pressure suction tube 5 form a negative pressure circuit, and the liquid and foreign matter in the oral cavity can be sucked out through the suction hole 13 by drawing negative pressure, while fresh liquid medicine can be sucked in through the injection hole 12, and no additional injection thrust is required at one end of the injection tube 4. In addition, in order to facilitate the control of negative pressure suction, a negative pressure switch 7 for controlling the conduction of the negative pressure suction tube 5 is provided on the brush handle 2. In this way, a single person is allowed to operate the medical toothbrush, and the drug flushing and extraction can be achieved by operating the negative pressure switch 7 on the toothbrush with one hand.

[0023] In this article, Figure 1 and Figure 2 As shown, the depression 312 of the concavo-convex structure 31 refers to a gap in the sponge layer extending from the outer surface of the sponge layer 3 toward the surface of the brush head 1 .

[0024] refer to Figure 3a and Figure 3b In some embodiments, the concave-convex structure 31 of the sponge layer 3 includes multiple rows of protrusions 311 spaced apart along the first direction A1, each row of protrusions 311 includes multiple protrusions 311 spaced apart along the second direction A2, and there are depressions 312 between adjacent protrusions 311, and the first direction A1 intersects with the second direction A2.

[0025] In some embodiments, the first direction A1 is perpendicular to the second direction A2.

[0026] In some embodiments, there is a first spacing d1 between two adjacent rows of protrusions 311 in the first direction A1, and the first spacing d1 is 1-1.5 mm. There is a second spacing d2 between two adjacent protrusions 311 in the second direction A2, and the second spacing d2 is 1-1.5 mm. The first width w1 of the protrusion 311 in the first direction A1 is 2.4-2.8 mm, and the second width w2 of the protrusion 311 in the second direction A2 is 2.4-2.8 mm. The first spacing d1 and the second spacing d2 may be the same or different. The first width w1 and the second width w2 may be the same or different.

[0027] In some embodiments, in the concavo-convex structure 31 of the sponge layer 3, there may be sponge or no sponge at the bottom of the concave 312. When there is no sponge at the bottom of the concave 312, the concave 312 runs through the entire thickness of the sponge layer 3, and the depth of the concave 312 is equal to the thickness of the sponge layer 3; when there is sponge at the bottom of the concave 312, the concave 312 does not run through the entire thickness of the sponge layer 3, and the depth of the concave 312 is less than the thickness of the sponge layer 3.

[0028] In some embodiments, the thickness T of the sponge layer 3 is 2.4-2.8 mm, for example, 2.6 mm.

[0029] In some embodiments, the sponge layer 3 is white. The white sponge is easy to observe and allows timely detection of bleeding or abnormal secretions when wiping the oral cavity.

[0030] In some embodiments, the brush handle 2, the injection tube 4 and the negative pressure suction tube 5 are all transparent. In this way, the color of the fluid in the injection tube 4 and the negative pressure suction tube 5 can be observed to judge the situation in the oral cavity.

[0031] In some embodiments, one end of the brush handle 2 connected to the brush head 1 is bendable to adjust the curvature between the brush head 1 and the brush handle 2. For example, one end of the brush handle 2 connected to the brush head 1 is made of a flexible material. In this way, the curvature of the brush head can be adjusted to effectively clean different parts of the oral cavity.

[0032] In some embodiments, anti-skid stripes 21, such as anti-skid horizontal stripes, are provided on the outer side of the brush handle 2 to achieve an anti-skid effect.

[0033] In some embodiments, the brush head 1 and the brush handle 2 are integrally formed.

[0034] In some embodiments, the diameter of the injection hole 12 is 0.7-0.8 mm. The number of the injection holes 12 can be adjusted according to factors such as the size of the brush head 1, and is not limited here.

[0035] In some embodiments, the concavo-convex structure 31 is provided on all surfaces of the brush head 1 except the first surface 11 , and the concavo-convex structures on each surface may be the same or different.

[0036] In some embodiments, the diameter of the suction hole 13 is 0.9-1.1 mm. The number of the suction holes 13 can be adjusted according to factors such as the size of the brush head 1, and is not limited here.

[0037] In some embodiments, the negative pressure switch can be a ball valve structure (not shown), which is connected to the negative pressure suction tube. When the ball valve is opened, a passage connecting the suction hole 13 and the negative pressure source is formed in the negative pressure suction tube 5. When the ball valve is closed, the suction hole 13 and the negative pressure source are disconnected. Other valve structures that can be set on the brush handle 2 to control the conduction of the negative pressure suction tube 5 can also be imagined, which is not limited here.

[0038] Through the above technical solution provided by the utility model, through the combined design of the sponge layer 3 and the negative pressure switch 7, a single person can operate the toothbrush to provide oral injection and drug suction for the patient, and can effectively remove foreign matter cleaned from the oral affected area. In addition, the anti-slip stripes and the bendable brush handle further provide the medical toothbrush with operational reliability.

[0039] Although the embodiments described herein are described with reference to specific embodiments, it should be understood that those skilled in the art will make various adjustments and changes thereto without departing from the scope and spirit of the present invention.
