• Safe swallowing to enjoy eating together


    GOKURI is currently available for non-medical devices, medical device version is under development

  • GOKURI vision

    A wearable device to monitor swallowing and a monitoring/analysis service, "GOKURI" watches over and supports your loved ones together so that they can enjoy eating for as long as possible

    Reduce the risk of aspiration

    Opportunities for appropriate medical intervention for poor oral function are frequently missed. By monitoring early signs of aspiration risk and taking proactive measures, the danger of future aspiration and post-febrile pneumonia is reduced.

    Aspiration pneumonia can be a preventable disease.

    Every year, approximately 40,000 lives are lost due to aspiration pneumonia without appropriate intervention. Early detection of signs of aspiration pneumonia and management of the condition before it gets critical is vital.

    Neckband 4

    Neckband 4, which is fully interlocked with the GOKURI system in the cloud, uses artificial intelligence (AI) to quantify swallowing. It monitors vital data by means of contact-type sensors (Patent No. 6903368). They are: swallowing and breathing sounds, the number of swallows and coughs, neck angle, pulse rate, temperature measurement function, and blood oxygen level. Both wireless (Bluetooth connection) and wired connections are supported and can be used according to the hospital environment.

  • GOKURI Cloud

    The GOKURI Cloud, a cloud system provided to medical professionals together with the Neckband 4, allows various data collected by the neckband to be managed and viewed on a dashboard.
    The dashboard facilitates information sharing among multiple professionals engaged in swallowing and care activities in the hospital wards, especially clinicians at different times of the day.

  • What GOKURI can do

    GOKURI presents the following features

    Measure swallowing sounds from the neck

    To monitor swallowing and eating, the Neckband 4 measures swallowing sounds, posture and vital data. In addition to swallowing sounds, the system can also capture aspiration risk signs such as coughs and resting breath sounds.

    The LED on the neckband turns green when a swallowing sound is detected. When a sound other than swallowing is detected, the LED lights up red.


    The Neckband 4 senses the neck angle in three degrees of freedom to measure posture data. At the beginning of a meal, the examiner can visually check on the app whether the examinee is in an appropriate posture or not.

    Protocols for swallowing screening tests

    Assessment of the eating patterns and rehabilitation progress of hospitalized patients by means of bedside swallowing function tests, such as Repeated Saliva Swallowing Test (RSST), Water Drinking Test, and Food Test, are fully supported by GOKURI app.

    Manage and monitor measurement data via cloud services

    With GOKURI's cloud dashboard system, GOKURI Portal, the results of each measurement for each person can be instantly recorded in the cloud database in a network environment. With GOKURI Portal, the number of swallows, the swallowing pace, the number of coughs, and other parameters are displayed along with vital data. It also allows the user to see who, when, and how the measurements were taken by the team as a whole.
