Description

A negative pressure suction toothbrush Technical Field

[0001] This utility model relates to the field of toothbrush technology, specifically to a negative pressure suction toothbrush. Background Technology

[0002] In the field of critical care medicine, endotracheal intubation via the mouth is a common and crucial life support method for establishing an artificial airway and ensuring respiratory support for critically ill patients. However, the long-term placement of endotracheal tubes (especially via the oral route), coupled with factors such as the patient's critical condition, weakened immunity, and loss of oral self-cleaning ability, poses a significant challenge to oral care. Failure to clean the patient's mouth will lead to a large accumulation of oral secretions, food debris (if small amounts of liquids are allowed to be consumed orally), microorganisms (bacteria and fungi), and sloughed mucosal cells.

[0003] Currently used clinical oral care methods, such as wiping with cotton balls or sponge swabs soaked in saline or mouthwash, have obvious drawbacks in terms of low efficiency and incomplete cleaning in patients with endotracheal intubation. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a negative pressure suction toothbrush to solve the technical problems of low efficiency and incomplete cleaning in the existing oral care methods.

[0005] To solve the above-mentioned technical problems, this utility model provides a negative pressure suction toothbrush, comprising:

[0006] The toothbrush body includes a brush head and a handle. The upper surface of the brush head is provided with a bristle area and a notch in the bristle area. The notch extends towards the handle to the edge of the bristle area. Both the brush head and the handle are provided with interconnected negative pressure channels. The end of the handle away from the brush head is provided with a connector that communicates with the negative pressure channels and is used to connect with a negative pressure device. The bottom end of the brush head is provided with several negative pressure holes that communicate with the negative pressure channels.

[0007] The rinsing tube is connected to the brush handle, with its front end located inside the notch. The height of the rinsing tube is lower than the height of the bristle area.

[0008] A fixing component is located on the upper end face of the brush handle and is used to fix the rinsing tube.

[0009] With the above structure, the negative pressure suction toothbrush of this utility model has the following advantages: the brush head enters the patient's mouth for cleaning, the rinsing tube can inject cleaning water into the mouth for rinsing, and during and after cleaning, the cleaning water and oral secretions in the mouth can be sucked out through the negative pressure hole, ensuring basic cleaning of the patient's mouth. Compared with cotton balls or sponge sticks dipped in saline or mouthwash, the toothbrush cleaning method is more efficient and has a better cleaning effect.

[0010] As an improvement, the bottom of the brush head is provided with several hemispherical protrusions, and each protrusion has an opening for a negative pressure hole formed at its bottom. With this structure, the opening of the negative pressure hole is set on the protruding protrusion, so that the opening of the negative pressure hole protrudes outside the bottom of the brush head, which is conducive to the negative pressure hole absorbing clean water and secretions in the mouth.

[0011] As an improvement, the brush head includes a bristle section and a transition section located at the rear end of the bristle section. The bristle area is located on the upper surface of the bristle section, and the rear end of the transition section is detachably connected to the brush handle. With this structure, the brush head needs to enter the patient's mouth for cleaning. Its detachable connection to the brush handle allows the cleaning effect to be maintained by replacing the brush head. The transition section frequently enters and exits the oral cavity during the cleaning process and is replaced together with the brush head.

[0012] As an improvement, the rear end of the transition section is provided with an insertion part, and the front end of the brush handle is provided with a socket for the insertion part to be inserted; this structure has the advantages of easy connection and disassembly.

[0013] As an improvement, the negative pressure channel includes a first channel inside the brush head and a second channel inside the brush handle. The rear end of the insertion part has a plug with an outer diameter smaller than that of the insertion part. The first channel extends to the plug and passes through the rear end face of the plug. A suction tube is connected inside the brush handle. The second channel is located inside the suction tube. The front end of the suction tube is flush with the rear end face of the plug and allows the plug to be inserted. The diameter of the second channel matches the outer diameter of the plug. The rear end of the suction tube protrudes from the rear end of the brush handle and forms a connector. With this structure, when the insertion part is inserted into the plug, the plug is also inserted into the second channel of the suction tube, completing the connection between the first channel and the second channel, which is convenient for installation.

[0014] As an improvement, the brush handle includes a detachably connected upper housing and a lower housing. Both the upper and lower housings have slots at their front ends. The slots of the upper housing and the lower housing are joined together to form an insertion port. Both the upper and lower housings have mounting grooves located at the rear end of the slots and communicating with the slots. The mounting grooves of the upper housing and the lower housing are joined together to accommodate the suction tube. With this structure, the upper and lower housings are detachably connected, which facilitates cleaning and disinfection of the upper and lower housings and also makes it easy to replace the suction tube.

[0015] As an improvement, a ring protrusion is provided on the outer peripheral wall of the plug; with this structure, the ring protrusion is inserted into the second channel along with the plug, which can play a certain sealing role.

[0016] As an improvement, a protrusion is provided at the bottom of the front end of the rinsing tube, and a limiting groove is provided on the upper surface of the brush head. The protrusion is interference-fitted into the limiting groove. This structure improves the stability of the connection between the brush head and the rinsing tube.

[0017] As an improvement, the fixing component includes an arc-shaped groove on the upper end face of the brush handle, which extends along the length of the brush handle; this structure has the advantages of simple structure and stable connection. Attached Figure Description

[0025] The following is a detailed description of a negative pressure suction toothbrush according to the present invention, with reference to the accompanying drawings.

[0026] As shown in Figures 1 to 6, a negative pressure suction toothbrush includes a toothbrush body, a rinsing tube 7, and a fixing component. The toothbrush body includes a brush head 1 and a handle 2. As shown in Figure 4, the upper surface of the brush head 1 is provided with a bristle area 3, and the bristle area 3 is provided with a notch 4. The notch 4 extends towards the handle 2 to the edge of the bristle area 3. The rinsing tube 7 is connected to the handle 2 and the front end of the rinsing tube 7 is located inside the notch 4. The height of the rinsing tube 7 is lower than the height of the bristle area 3. The fixing component is provided on the upper surface of the handle 2 and is used to fix the rinsing tube 7.

[0027] As shown in Figures 1 and 4, the brush head 1 includes a bristle section 101 and a transition section 102 located at the rear end of the bristle section 101. A bristle area 3 is located on the upper surface of the bristle section 101. The rear end of the transition section 102 is detachably connected to the brush handle 2. The bristle section 101 enters the patient's mouth for cleaning. During the cleaning process, the transition section 102 continuously enters and exits the oral cavity. This means that only the brush head 1 enters the patient's mouth during the entire cleaning process, while the brush handle 2 does not. After basic disinfection, the brush handle 2 can be reused. Because a tube is inserted into the patient's mouth, the brush head 1 is sized according to the size of a children's toothbrush for easy cleaning. To further prevent the brush handle 2 from entering the patient's mouth, the length of the transition section 102 can be appropriately increased.

[0028] As shown in Figure 1, the bottom of the front end of the rinsing tube 7 has a protrusion 18, and the upper end face of the brush head 1 has a limiting groove 19. The protrusion 18 is interference-fitted into the limiting groove 19. As shown in Figure 6, the fixing component includes an arc-shaped groove 20 on the upper end face of the brush handle 2, which extends along the length of the brush handle 2. The rinsing tube 7 is made of medical rubber tubing, thus it is flexible. The opening of the arc-shaped groove 20 is smaller than the outer diameter of the rinsing tube 7. Therefore, by causing the rinsing tube 7 to undergo elastic deformation, it is snapped into the arc-shaped groove 20. The connection between the rinsing tube 7 and the brush handle 2 is stable and easy to disassemble. The rinsing tube 7 is not detachable from the brush head 1. When replacing the brush head 1, the rinsing tube 7 is replaced together with it.

[0029] As shown in Figure 1, the rear end of the transition section 102 is provided with an insertion section 9, and the front end of the brush handle 2 is provided with a socket 10 for the insertion section 9 to be inserted.

[0030] As shown in Figure 1, both the brush head 1 and the brush handle 2 are provided with interconnected negative pressure channels. The brush handle 2, at the end away from the brush head 1, is provided with a connector 5 that communicates with the negative pressure channels and is used to connect with a negative pressure device. The bottom end of the brush head 1 is provided with several negative pressure holes 6 that communicate with the negative pressure channels. As shown in Figure 2, the bottom end of the brush head 1 is provided with several hemispherical protrusions 8, and each protrusion 8 has an opening of a negative pressure hole 6 formed at its bottom end.

[0031] As shown in Figures 1 and 3, the negative pressure channel includes a first channel 11 located inside the brush head 1 and a second channel 12 located inside the brush handle 2. The rear end of the insertion part 9 has a plug 13 with an outer diameter smaller than that of the insertion part 9. The first channel 11 extends to the plug 13 and penetrates its rear end face. A suction tube 14 is connected inside the brush handle 2. The second channel 12 is located inside the suction tube 14. The front end of the suction tube 14 is flush with the rear end face of the insertion port 10 and allows the plug 13 to be inserted. The diameter of the second channel 12 matches the outer diameter of the plug 13. The rear end of the suction tube 14 protrudes from the rear end of the brush handle 2, forming a connector 5. An annular protrusion 17 is provided on the outer peripheral wall of the plug 13.

[0032] As shown in Figures 5 and 6, the brush handle 2 includes a detachably connected upper housing 201 and a lower housing 202. Both the upper housing 201 and the lower housing 202 have slots 15 at their front ends. The slots 15 of the upper housing 201 and the lower housing 202 are combined to form an insertion port 10. Both the upper housing 201 and the lower housing 202 have mounting grooves 16 located at the rear end of the slots 15 and communicating with them. The mounting grooves 16 of the upper housing 201 and the lower housing 202, when combined, are used to accommodate the suction tube 14. The detachable connection between the upper housing 201 and the lower housing 202 facilitates cleaning and disinfection of both housings and also makes it easy to replace the suction tube 14. The upper housing 201 and the lower housing 202 employ a snap-fit ​​connection method common in the prior art.

[0033] The brush head 1 enters the patient's mouth for cleaning, and the rinsing tube 7 can inject cleaning water into the mouth for rinsing. During and after cleaning, the cleaning water and oral secretions in the mouth can be sucked out through the negative pressure hole 6 to ensure basic cleaning of the patient's mouth. Compared with cotton balls or sponge sticks dipped in saline or mouthwash, the toothbrush method of cleaning the mouth is more efficient and has a better cleaning effect.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiment. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
