[0002] For patients who are bedridden for a long time, have inconvenient movement after surgery or have a stroke, the oral cavity cannot be well cleaned, which is easy to breed bacteria and produce odor. In severe cases, it will even lead to oral erosion. Traditional toothbrushes only have the function of brushing teeth, which is not conducive to discharging the cleaning liquid in the oral cavity. Moreover, for patients who are bedridden for a long time, due to inconvenient postures, sputum is not easy to discharge, which causes discomfort to the patients for a long time. The sputum remains in the oral cavity, between the teeth and on the tongue coating. Traditional toothbrushes can only simply clean the oral cavity of the human body, but cannot clean the sputum and other liquids in time. Content of the Utility Model
[0003] The purpose of the utility model is to provide a cleaning toothbrush for patients, which can solve the above technical problems.
[0004] The utility model provides a cleaning toothbrush for patients, which comprises a toothbrush head, a toothbrush rod and a toothbrush handle connected in sequence. A cleaning component is arranged on the toothbrush head. A water injection pipe is arranged at the tail end of the toothbrush handle. A plurality of water overflow ports are arranged on the toothbrush head. The water injection pipe is connected with a water inlet channel, and the water inlet channel penetrates through the toothbrush handle and the toothbrush rod and is communicated with the water overflow ports. A negative pressure channel is arranged in parallel on one side of the water inlet channel. Two ends of the negative pressure channel are respectively connected with a negative pressure pipe located at the tail end of the toothbrush handle and a negative pressure suction port located at the toothbrush head. The negative pressure channel penetrates through the outer wall of the toothbrush handle to form a negative pressure pressing port.
[0005] The water injection pipe is connected with a water inlet device, and the negative pressure pipe is connected with a negative pressure device.

[0027] Embodiment 1
[0028] A cleaning toothbrush for patients, as Figure 1-2 shown, includes a toothbrush head 1, a toothbrush rod 2, and a toothbrush handle 3 that are connected in sequence. A cleaning assembly is provided on the toothbrush head 1. The cleaning assembly includes bristles 11 and a sponge block 12. The bristles 11 and the sponge block 12 are located on opposite sides of the toothbrush head 1. Water overflow ports 5 are evenly distributed among the bristles 11. The surface of the sponge block 12 is wavy, which fits the surfaces of teeth and gums, achieving thorough cleaning. It is made of polyurethane sponge and does not harm the oral cavity and gums. In addition, the bristles 11 mainly sweep and clean the residues, phlegm crusts, and secretions retained (i.e., attached) in the patient's tooth gaps and the inner side of the oral cavity. The sponge block 12 is more suitable for cleaning the oral mucosa, the upper palate, and the tongue surface than the bristles 11. The sizes of the bristles 11 and the sponge block 12 can be variously set according to the oral opening degree and size of different patients.
[0029] A water injection pipe 4 is provided at the tail end of the toothbrush handle 3. A plurality of water overflow ports 5 are provided on the toothbrush head 1. The water injection pipe 4 is connected to a water inlet channel 6. The water inlet channel 6 penetrates through the toothbrush handle 3 and the toothbrush rod 2 and is communicated with the water overflow ports 5. A negative pressure channel 7 is arranged in parallel on one side of the water inlet channel 6. Both ends of the negative pressure channel 7 are respectively connected to a negative pressure pipe 8 located at the tail end of the toothbrush handle 3 and a negative pressure suction port 9 located on the toothbrush head 1. There are a plurality of negative pressure suction ports 9 and they are evenly distributed on the side wall of the toothbrush head 1. The negative pressure channel 7 penetrates through the outer wall of the toothbrush handle 3 to form a negative pressure pressing port 10. Specifically, the above-mentioned water injection pipe 4 is connected to a water inlet device, and the negative pressure pipe 8 is connected to a negative pressure device. Both the water inlet device and the negative pressure device are existing devices, and usually the two are integrated on one device; such as the equipment with high-pressure flushing and negative pressure suction used in the existing oral treatment process. Its specific structure and working principle are well-known to those skilled in the art and will not be elaborated in detail here. When performing negative pressure extraction, the operator presses the negative pressure pressing port with a finger to achieve the work of negative pressure extraction.
[0030] Flow regulators 3 are provided on both the water injection pipe 4 and the negative pressure pipe 8. The flow regulator 3 is the roller type flow regulator used on the existing infusion pipe. By adjusting the degree of extrusion of the rollers of the flow regulator on the water injection pipe 4 and the negative pressure pipe 8, the flow rates of the water injection pipe 4 and the negative pressure pipe 8 can be adjusted. The outer surface of the brush handle 3 is provided with anti-slip protrusions 14. The anti-slip protrusions 14 are of annular structure and are evenly distributed along the axial direction of the brush handle 3.
[0031] Embodiment 2
[0032] As Figure 3 shown, the basic structure is the same as that of Embodiment 1, except that there is an angle between the horizontal line where the brush head 1 and the brush rod 2 are located, and the angle is 15 degrees.
[0033] Embodiment 3
[0034] As Figure 1-2 shown in and 4-5, the basic structure is the same as that of Embodiment 1, except that a sealing plug 15 is provided at the negative pressure port 10. The cross-sectional size and shape of the sealing plug 15 are the same as those of the negative pressure port 10. Support bars 16 and a spring 17 are provided inside the negative pressure port 10. One end of the spring 17 is fixedly connected to the support bar 16, and the other end of the spring 17 is fixedly connected to the sealing plug 15. On both sides of the side of the sealing plug 15 close to the negative pressure port 10, guide rods 18 are fixedly connected. The guide rods 18 are attached to the inner wall of the negative pressure port 10 and the ends are located inside the negative pressure port 10. The guide rods 18 enable the sealing plug 15 to move in the vertical direction. When in use, by pressing the sealing plug 15 with the thumb, it moves downward to block the negative pressure port 10. At this time, under the suction action of the negative pressure device, a negative pressure is formed in the negative pressure channel 7, and the cleaned waste liquid in the oral cavity can be sucked out of the oral cavity through the negative pressure channel 7 and the negative pressure pipe 8. When the sealing plug 15 is released, under the action of the spring 17, the sealing plug 15 leaves the negative pressure port 10, and the negative pressure in the negative pressure channel 7 disappears, and the liquid in the oral cavity cannot be sucked out. The generation and disappearance of the negative pressure can be conveniently controlled by pressing the sealing plug 15. In addition, with the presence of the sealing plug 15, the operator's thumb can be prevented from directly contacting the liquid in the negative pressure channel 7, preventing cross-infection.
[0035] Working and using process:
[0036] The operator inserts the brush head 1 part into the patient's oral cavity, starts the water inlet device, and the cleaning liquid is discharged through the overflow port 5. The oral cavity is comprehensively cleaned using the bristles 11 and the sponge block 12 for different parts respectively. When there is more liquid in the oral cavity, seal the negative pressure port 10, and a negative pressure is formed in the negative pressure channel 7. The liquid in the oral cavity can be sucked out of the oral cavity through the negative pressure channel 7 and the negative pressure pipe 8. This device can not only perform oral care and cleaning, but also carry out negative pressure suction work on the liquid in the oral cavity, achieving the effect of quickly cleaning the oral cavity and ensuring the cleanliness and hygiene of the oral cavity.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
