Description

Technical Field

[0001] This utility model relates to the field of toothbrush technology, specifically to a toothbrush with a replaceable sponge head that can be used after tooth extraction. Background Technology

[0002] Oral health is an important component of overall health, and tooth extraction is one of the most common treatments in oral surgery. Effective postoperative wound care is crucial for promoting healing, preventing infection (such as dry socket), and reducing pain and swelling. Maintaining oral hygiene in the area surrounding the extraction wound is the core aspect of postoperative care. Traditional toothbrushes have three main problems when cleaning the mouth: first, physical irritation, as the bristles can easily touch the surgical wound, causing pain, bleeding, or even wound tearing; second, blind spots, as the brush head structure cannot adapt to postoperative swelling and makes it difficult to thoroughly clean the area surrounding the wound; and third, the risk of cross-infection, as blood and bacteria residue on the bristles can lead to secondary infections with repeated use.

[0003] Currently, patients mostly rely on cotton swabs or mouthwash to clean, but cotton swabs are not strong enough, and mouthwash cannot physically remove food residue. Although there are postoperative silicone toothbrushes available, their one-piece brush heads still pose a risk of rubbing against the wound and cannot adjust the cleaning intensity according to the healing stage. Therefore, there is an urgent need to develop a special toothbrush that allows for flexible contact, zoned cleaning, and replaceable consumables to achieve effective cleaning while ensuring wound safety. Utility Model Content

[0004] The purpose of this invention is to provide a replaceable sponge-headed toothbrush after tooth extraction, to solve the following three problems with traditional toothbrushes used for oral cleaning mentioned in the background art: first, physical irritation, as the bristles can easily touch the surgical wound, causing pain, bleeding, or even wound tearing; second, blind spots, as the brush head structure cannot adapt to the postoperative swelling, making it difficult to thoroughly clean the area near the wound; and third, the risk of cross-infection, as bloodstains and bacteria remain on the bristles, and repeated use may cause secondary infection.

[0005] Currently, patients mostly rely on cotton swabs or mouthwash to clean, but cotton swabs are not strong enough, and mouthwash cannot physically remove food residue. Although there are now silicone toothbrushes specifically designed for postoperative patients, their one-piece brush heads still pose a risk of rubbing against the wound and cannot adjust the cleaning intensity according to the healing stage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a replaceable sponge-headed toothbrush after tooth extraction, comprising a handle, a brush head, and bristles. The brush head is provided with bristles, and a U-shaped groove is provided at the end of the brush head away from the handle. A replaceable sponge cleaning pad is installed in the U-shaped groove. The replaceable sponge cleaning pad is a U-shaped structure that is interference-fitted with the U-shaped groove. Side limit blocks are provided on both sides of the brush head, and front limit strips are provided at the top and bottom of the front end of the brush head.

[0007] Preferably, the replaceable sponge cleaning pad includes a sponge cleaning pad stabilizer and a sponge cleaning pad, the sponge cleaning pad stabilizer and the sponge cleaning pad are an integral structure, and the cross-section of the sponge cleaning pad stabilizer is higher than the cross-section of the sponge cleaning pad, while the length of the sponge cleaning pad stabilizer is longer than the length of the sponge cleaning pad.

[0008] Preferably, the side stop limiting block and the brush head are integrally formed, and the side stop limiting block has several openings.

[0009] Preferably, the brush bristles are provided with a concave arc.

[0010] Preferably, the brush handle and brush head are integrally formed.

[0011] Preferably, the sponge cleaning pad stabilizer is made of silicone material.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the toothbrush with a replaceable sponge head can be used after tooth extraction.

[0013] (1) By adding a replaceable sponge cleaning pad to the brush head, the brush can be prevented from directly contacting the wound. The flexibility of the replaceable sponge cleaning pad can reduce the patient's fear.

[0014] (2) The sponge cleaning pad uses medical-grade hemostatic sponge, which can effectively maintain oral hygiene of the wound and adjacent areas while avoiding bleeding and tearing caused by secondary contact of the toothbrush with the wound.

[0015] (3) The “replaceable” design ensures that the sponge pad is replaced after use or periodically to keep the toothbrush hygienic, prevent bacterial growth, and avoid secondary infection that may be caused by repeated use.

[0016] (4) Green, environmentally friendly and low-cost, the sponge cleaning pad can be replaced separately, the toothbrush body can be reused, reducing long-term use costs, saving resources and reducing environmental pollution. The sponge cleaning pad can clean blind spots, and when combined with the brush head structure, it can adapt to the postoperative swelling shape and solve the problem of difficulty in thoroughly cleaning the area near the wound.

[0017] (5) Easy to clean after use. The side guard limit block has an opening that makes it easier to shake off the water in the stable part by swinging the toothbrush. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7 This utility model provides a technical solution: a replaceable sponge-tipped toothbrush after tooth extraction, including a handle 1, a brush head 2, and bristles 3. The brush head 2 is provided with bristles 3, and a U-shaped groove is provided at the end of the brush head 2 away from the handle 1 to facilitate the installation of a replaceable sponge cleaning pad 4. The replaceable sponge cleaning pad 4 is installed in the U-shaped groove, which can prevent the brush from directly contacting the wound and effectively maintain oral hygiene in the wound and adjacent areas. At the same time, the replaceable sponge cleaning pad 4 is a U-shaped structure that is interference-fitted with the U-shaped groove. Side limit blocks 5 are provided on both sides of the brush head 2 to limit the displacement of the replaceable sponge cleaning pad 4 in the X direction, and front limit strips 6 are provided at the top and bottom of the front end of the brush head 2 to limit the displacement of the replaceable sponge cleaning pad 4 in the Y and Z directions.

[0028] The replaceable sponge cleaning pad 4 in this example includes a sponge cleaning pad stabilizer 401 and a sponge cleaning pad 402. The sponge cleaning pad stabilizer 401 and the sponge cleaning pad 402 are an integral structure. The sponge cleaning pad and the sponge cleaning pad stabilizer are tightly connected. The cross-section of the sponge cleaning pad stabilizer 401 is higher than the cross-section of the sponge cleaning pad 402. At the same time, the length of the sponge cleaning pad stabilizer 401 is longer than the length of the sponge cleaning pad 402. This allows the sponge cleaning pad stabilizer 401 to be engaged in the U-shaped groove on the brush head 2, while the sponge cleaning pad 402 can also protrude from the brush head 2 for easy use.

[0029] In this example, the side guard limiting block 5 and the brush head 2 are integrally formed, and the side guard limiting block 5 has several openings 501. The openings 501 not only facilitate the installation of the replaceable sponge cleaning pad, but also allow the water accumulated in the stabilizing part to be shaken off by swinging the toothbrush, reducing the growth of bacteria. There is a gap between the side guard limiting block 5 and the U-shaped groove on the brush head 2, which facilitates the insertion of the sponge cleaning pad stabilizing part 401.

[0030] In this example, the bristles 3 are designed with a concave arc, which makes it easy to clean the oral cavity and other areas except for wounds.

[0031] In this example, the brush handle 1 and brush head 2 are integrally molded, which improves hygiene.

[0032] In this example, the sponge cleaning pad stabilizer 401 is made of silicone material, and the sponge cleaning pad 402 is made of medical sponge material. The silicone material sponge cleaning pad stabilizer 401 has a certain degree of flexibility, is easy to disassemble, and is safe and hygienic. The medical sponge material sponge cleaning pad 402 has flexibility and is not likely to cause secondary damage to the cavity.

[0033] Working principle: Before use, install the replaceable sponge cleaning pad 4 into the U-shaped groove on the brush head 2. During installation, insert both sides of the sponge cleaning pad stabilizer 401 into the side stop limit block 5 of the brush head 2 through the U-shaped groove, and then insert the semi-circular part of the sponge cleaning pad stabilizer 401 into the front stop limit strip 6 of the brush head 2. The installation is now complete.

[0034] When using, clean the wound and surrounding oral cavity with the sponge cleaning pad 402, and clean other areas of the mouth except the wound with the bristles of the toothbrush body.

[0035] After use, the replaceable sponge cleaning pad 402 can be dragged off by first pulling out one side of the sponge cleaning pad retainer 401 from the side stop block 5 of the brush head 2, and then pulling out the semi-circular part of the sponge cleaning pad retainer 401 from the front stop stop strip 6 of the brush head 2. In this way, the replaceable sponge cleaning pad 4 can be easily removed. After removing the replaceable sponge cleaning pad 4, the water accumulated in the brush head 2 can be shaken off by shaking the toothbrush to reduce the growth of bacteria. This completes the whole work. The contents not described in detail in this manual are existing technologies known to those skilled in the art.
