Abstract
Description
Technical Field
[0001] This utility model relates to the field of oral care devices, and in particular to an oral care device for acute and critical illnesses. Background Technology
[0002] Critically ill patients require oral care devices primarily based on the following aspects: Critically ill patients typically refer to those with severe, urgent illnesses whose lives are threatened and who require immediate treatment. These patients are often comatose, unconscious, or unable to move independently, thus unable to perform oral cleaning and care themselves. However, good oral hygiene is crucial for preventing infection and promoting recovery. Traditional oral care methods, such as using cotton swabs moistened with water, while simple and easy to perform, are inefficient and may increase the risk of infection due to improper operation. Furthermore, these methods cannot meet the specific oral cleaning needs of critically ill patients. To improve the effectiveness of oral care for critically ill patients and reduce the occurrence of complications, healthcare professionals have begun to seek more efficient and safer oral care devices. These devices typically combine modern medical technology and design concepts to achieve automated and intelligent oral cleaning and care. One critically ill patient oral care device includes a water-filled plastic bottle, a cap, and a replacement mechanism. The replacement mechanism allows healthcare professionals to quickly change the sponge used to moisten the patient's lips, thereby improving care efficiency and reducing the risk of cross-infection. It combines modern medical technology and design concepts, aiming to provide more efficient, safe, and convenient oral care services for critically ill patients.
[0003] Critically ill patients are often unable to perform effective oral hygiene due to the severity of their condition, leading to bacterial growth in the mouth and increasing the risk of infection. Traditional oral care methods are inefficient and may cause discomfort to patients or even lead to more serious complications if not performed properly. Therefore, we propose an oral care device for critically ill patients to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide an oral care device for critically ill patients to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The nebulized liquid can be inhaled by the patient through the outer baffle and the mouth plug, thereby achieving the purpose of oral care.
[0015] This utility model has a reasonable structural design. Through the cooperation of multiple structures, the filter cloth can be quickly disassembled for replacement and cleaning, which helps to keep the device clean and hygienic. It is easy to operate and can effectively provide oral care for critically ill patients, while ensuring the purity and suitability of the nursing fluid. Attached Figure Description
