Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an oral care brush. Background Technology
[0002] In oral care, especially for patients who cannot perform effective oral cleaning independently, such as comatose patients or postoperative patients, traditional oral care methods typically involve using oral brushes. This cleaning process generates a large amount of oral secretions and rinsing solutions. If these liquids are not removed promptly, they can easily cause choking, aspiration, and serious complications such as aspiration pneumonia, increasing patient suffering and treatment costs.
[0003] Traditional oral care brushes generally consist of two main parts: a brush head and a handle. The brush head is made entirely of sponge, which poses a risk of choking if a patient suddenly closes their mouth and bites off the sponge. Furthermore, the sponge becomes too soft when wet, weakening its cleaning power and resulting in incomplete cleaning. Another type of oral care brush uses a toothbrush head with a sponge on the back. This head is harder and can easily cause mucosal damage during use.
[0004] Therefore, there is an urgent need to design a stable, safe, and thorough cleaning brush to solve the above problems. Utility Model Content

[0030] Example
[0031] An oral care brush, such as Figure 1 and Figure 5 As shown, it includes a brush head 1 and a brush handle 2. The brush head 1 has multiple protruding bristles 101. A cleaning sponge 3 is fixedly connected to the center of the front of the brush head 1. The brush handle 2 is inserted into the brush head 1 along the center line of the brush head 1. The brush handle 2 has a drainage cavity inside. The brush head 1 has a suction hole through it, and the suction hole communicates with the drainage cavity.
[0032] like Figure 2 and Figure 6As shown, the brush head 1 is oval in shape, with a length of 2.8-3.2cm, a width of 1.8-2.2cm, and a thickness of 0.8-1.2cm, preferably 3cm in length, 2cm in width, and 1cm in thickness. The cleaning sponge 3 is also oval in shape, with its center coinciding with the center of the brush head 1. The cleaning sponge 3 is made of polyurethane sponge. Mouthwash can be applied to the cleaning sponge 3 during use to moisten the mouth. The brush head 1 is made of silicone, and has multiple bristles 101 on its front and sides. The bristles 101 are also made of silicone and are integrally molded with the brush head 1. The silicone brush head 1 and bristles 101 are soft and elastic, allowing them to reach deep into the gaps between teeth and the gingival sulcus for thorough cleaning of the oral cavity while maximizing the protection of the oral mucosa. The side of the cleaning sponge 3 furthest from the brush head 1 is at least as high as the ends of the bristles 101 furthest from the brush head 1.
[0033] like Figure 3 and Figure 7 As shown, a tongue brush 4 is integrally formed on the back of the brush head 1. The tongue brush 4 includes a first protrusion component 401 and two second protrusion components 402. The first protrusion component 401 is located in the center of the back of the brush head 1, and the two second protrusion components 402 are symmetrically arranged at both ends of the first protrusion component 401. The first protrusion component 401 is composed of two symmetrical arc-shaped strips connected at both ends, and the two ends of the first protrusion component 401 in the short axis direction of the brush head 1 are pointed. The second protrusion component 402 is a long strip forming three arrow-shaped structures of increasing size connected end to end. The two ends of the long strip are not connected, and the two smaller arrows are located at both ends of the brush head 1.
[0034] The tongue brush 4 provided by this utility model has a first protrusion component 401 and a second protrusion component 402 that can thoroughly clean all areas of the tongue and increase the friction between the tongue brush 4 and the tongue, thereby improving the cleaning effect.
[0035] The suction holes include a first suction hole 102 and a second suction hole 103. A first suction hole 102 is provided at each end of the front of the brush head 1 along its long axis. Four second suction holes 103 are provided on the side of the brush head 1, arranged in pairs at each end of the short axis of the brush head 1. Two first inlets 201 communicating with the first suction holes 102 are provided on the side wall of the brush handle 2. Four hollow side rods 202 are provided on the upper side wall of the brush handle 2. Figure 4As shown, each of the four side rods 202 has a second inlet 203 at its end furthest from the brush handle 2. Each of the four second inlets 203 communicates with one of the four second suction holes 103 on the side of the brush head 1. The brush handle 2 has a drainage cavity inside, and both the first inlet 201 and the second inlet 203 communicate with this drainage cavity. The side rods 202 are integrally formed with the brush handle 2, ensuring unobstructed flow between the second suction holes 103 and the drainage cavity, preventing obstruction of sputum suction when the patient bites down on the brush head 1.
[0036] The brush head 1 is a solid structure with an internal groove for holding the brush handle 2 and the side rod 202. The brush handle 2 and the side rod 202 are fixedly connected to the inside of the brush head 1. Alternatively, the side rod 202 can be directly fixed inside the brush head 1. A second inlet 203 is provided on the side wall of the brush handle 2. During installation, the second inlet 203 on the brush handle 2 is aligned and fixed with the side rod 202.
[0037] The brush handle 2 is made of ABS plastic, which is not easily bitten off. A connecting tube 5 is fixed to the end of the brush handle 2 furthest from the brush head 1. The connecting tube 5 is connected to the negative pressure device, and a side hole 501 is provided on the side wall of the connecting tube 5. The connecting tube 5 is a conventional component in this field. In use, the connecting tube 5 is connected to the negative pressure device, and the operator uses their thumb to block the side hole 501 to achieve a negative pressure suction effect. Sputum, excess saliva, or rinsing fluid in the patient's mouth is suctioned out through the first suction hole 102 and the second suction hole 103, and then flows through the drainage cavity of the brush handle 2 into the negative pressure suction device. The number and position of the first suction hole 102 and the second suction hole 103 can also be set as needed.
[0038] Meanwhile, superhydrophobic materials or anti-stick coatings are sprayed on the inner walls of the first suction hole 102, the second suction hole 103, the first inlet 201, the second inlet 203, the side rod 202, and the drainage cavity of the brush handle 2, so that the sputum inside the patient's mouth can smoothly enter the negative pressure device.
[0039] The oral care brush provided by this utility model is a disposable medical product. The brush head is made of silicone, which ensures effective cleaning while protecting the integrity of the oral mucosa to the greatest extent. The cleaning sponge is placed on the brush head to prevent patients from biting it off and accidentally sucking it out. At the same time, a tongue brush is provided to thoroughly clean the patient's mouth. The brush handle is made of ABS material, which is not easy to bite off. When used with the suction hole and negative pressure device on the brush head, it can effectively clean the oral cavity.
