Orabubble Co., Ltd. (Headquarters: Kanda-machi, Miyako-gun, Fukuoka; Representative Director: Satoru Ogawara) aims to realize a society where all elderly people are freed from the threat of aspiration pneumonia and can lead healthy lives every day through "Orabubble," a mouthpiece-type oral irrigator utilizing fine bubble technology.
■ The crisis of "oral frailty," the gateway to aspiration pneumonia
For the elderly, daily "meals" are one of their great pleasures. However, as the ability to swallow (swallowing function) declines with age, food and saliva are more likely to enter the trachea by mistake, increasing the risk of causing "aspiration pneumonia." This pneumonia does not just happen suddenly one day. As a preceding stage, signs of "oral frailty" (weakness of oral functions) are hidden, indicating minor declines in oral function such as "increased food spillage," "choking on tea or soup," and "poor articulation." Noticing this at this stage and performing appropriate "maintenance of oral hygiene" and "oral function training" is the biggest key to halting functional decline and preventing aspiration pneumonia.
■ Cost containment for medical and nursing care and contribution to society brought about by "zero aspiration pneumonia"
Preventing aspiration pneumonia goes beyond just protecting the individual's life and health. It directly connects to preventing sudden hospital admissions due to pneumonia and stopping muscle weakness and the deterioration of the care level (required nursing care level) caused by long-term bed rest. Extending the period during which elderly people can live energetically in the places they are accustomed to (healthy life expectancy) greatly reduces the physical and mental burden on their families and care workers. At the same time, we are convinced that this will curb the ever-expanding increase in medical and nursing care costs, ultimately leading to a reduction in the country's social security expenses. Daily "oral care" is a social action that will save the future of Japan.
■ Protecting oral health with daily "water-only" care
The first step to making our dream come true is "Orabubble," a mouthpiece-type oral irrigator utilizing fine bubble technology.
- Can be cleaned with "only water" without using electricity: A Venturi structure generates microbubbles and assists in cleaning the oral cavity using water flow. It is possible to clean the oral cavity using only water, without using toothpaste or mouthwash conventionally used.
- Safety-conscious design: Adopts a structure equipped with an exhaust path for the cleaning water, and is designed in consideration of the retention of water in the mouth during use.
- A trigger to move the mouth: By holding the mouthpiece in the mouth, it is structured to circulate the water flow throughout the entire oral cavity, and can be utilized as one of the options for performing oral care.
*Caution: This product is intended for those who have become unable to brush their teeth well, and it cannot remove objects caught between teeth or tartar. Please continue to have professional oral care as before. Also, it is not suitable for those who cause aspiration every time they eat.
■ A challenge born from knowing the realities of medical and welfare settings
Representative Satoru Ogawara concurrently serves as an internal medicine doctor, chairman of a social welfare corporation, and a visiting professor at a university's faculty of engineering, and conducts product development utilizing his specialized knowledge and network in medicine, nursing care, and engineering. While interacting with many elderly people on site, the strong desire of "Isn't there a way to keep the inside of the mouth clean more easily and effectively?" became the origin of Orabubble's development. We will continue to work so that all elderly people can enjoy delicious meals with their own mouths until the very end, preventing aspiration pneumonia.
