Description

Technical Field

[0001] The utility model relates to the technical field of medical care equipment, in particular to an oral care device. Background Art

[0002] Oral care for bedridden patients can help keep the oral cavity clean and moist, prevent oral infections, prevent or reduce bad breath, and remove dental plaque.

[0003] In the prior art, when performing oral care on bedridden patients, tweezers are usually used to hold a wet gauze ball to scrub the teeth. During the care, the lingual side, buccal side, and alveolar side of the teeth need to be fully scrubbed, so the efficiency is low, and the lingual side and buccal side of the teeth are not easy to scrub clean. At the same time, the scrubbing water overflowed from the gauze ball during the scrubbing process cannot be discharged from the oral cavity.

[0004] In addition, negative pressure toothbrushes have also appeared in the prior art. For example, the utility model patent with application number 202320846705X discloses a visual negative pressure toothbrush for oral cleaning of comatose patients. The negative pressure toothbrush has only one brush head, and both the flushing liquid hole and the negative pressure hole are set on the brush head. This will cause part of the cleaning liquid to be sucked away by the negative pressure hole of the attachment without sufficient contact with the teeth after flowing out, resulting in poor flushing effect. In addition, since some cleaning liquid is far away from the negative pressure hole, it will remain in the mouth after brushing and cannot be sucked by the negative pressure hole. If the residual cleaning liquid enters the patient's trachea, it may cause choking and coughing problems. And because the negative pressure toothbrush cannot generate negative pressure by itself, the hospital's negative pressure system is required to provide negative pressure, resulting in the existing negative pressure toothbrush needing to be used under hospital conditions, and cannot meet the requirements of patients for use at home.
