Description

[0001] This invention application is a divisional application of the invention application filed on July 22, 2024, with application number 202410979207.1 and invention title "A biting and opening lip device, oral care device and system". Technical Field

[0002] This invention relates to the field of oral care technology, and in particular to an occlusal lip opening device, an oral care device and system. Background Technology

[0003] Oral care for comatose and long-term bedridden patients is an indispensable part of intensive care and emergency medical care. However, traditional oral care methods for these patients have some limitations. Comatose patients, lacking consciousness and mobility, cannot actively cooperate with oral care, and bedridden patients cannot perform oral care independently, which easily leads to problems such as oral bacterial infections, saliva retention, and bad breath. Long-term lack of effective oral care can disrupt oral microbial homeostasis, ultimately turning the oral cavity into a bacterial reservoir and becoming an inherent risk factor for systemic microbial infections.

[0004] Because patients are unable to clean their mouths independently, food debris and bacteria accumulate. Traditional oral care tools, such as oral suction devices and moistened cotton balls, suffer from drawbacks including inconvenience in operation, poor cleaning effectiveness, inability to fully cover all areas of the mouth, and potential damage to the oral mucosa. Some oral care devices have rinsing functions, but the rinse water requires an additional suction device to extract, which may be delayed or fail to reach deep into the mouth, leading to choking. Oral care for comatose patients typically relies on caregivers. During cleaning, patients may cover their mouths with their lips or have their jaws clenched, making effective oral care impossible. Existing care devices often lack angle adjustment, making it difficult to control the force and direction. Caregivers operate at the bedside in a face-to-face position, frequently needing to switch positions to care for the patient's mouth, adding difficulty and creating blind spots, increasing the risk of damaging oral soft tissues. In addition, traditional oral care devices can only clean the residue on relatively superficial areas such as bad breath and teeth, and cannot clean and care for plaque and food debris in hard-to-reach areas such as the occlusal surfaces of teeth and the distal surfaces of distal teeth. Moreover, during the care process, caregivers cannot see the patient's oral condition, which may lead to repeated cleaning or omissions, or even accidental damage to the patient's oral mucosa.

[0005] There are no effective solutions to the problems existing in the relevant technologies, such as the inability to adjust the angle of passive oral care devices, poor cleaning effect, incomplete suction of mouthwash, inability to effectively clean dental plaque on the patient's occipital surface, and incomplete cleaning due to the caregiver's inability to see the patient's oral cavity. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a biting and lip-opening device, an oral care device, and a system to solve problems such as the inability to adjust the angle of passive oral care devices, poor cleaning effect, incomplete suction of mouthwash, inability to effectively clean dental plaque on the patient's occlusal surface, and incomplete cleaning due to caregivers not being able to see the patient's oral cavity clearly.
