Description

Restroom posture assistance and emergency alarm system to prevent falls for the elderly

The present invention relates to toilet posture assistance and emergency alarm technology, and more particularly, toilet posture assistance and It is about an emergency alarm system.

Healthy old age, expressed by the number of healthy lifespan, should set the goal of medical practice not only for the treatment of diseases, but also for the quality of happy old age, while the elderly can lead independent and happy lives. To this end, it is necessary to identify in advance the risks of various life functions that interfere with independent living in old age and to devise preventive efforts.

On the other hand, in the case of the elderly, even in an indoor space, a situation in which they have to be treated in a hospital due to an accident such as a fall occurs very frequently. Statistically, safety accidents occur at the highest rate of 24.7% in the living room among indoor spaces, 22.4% in the bedroom, and 17.3% in the bathroom including the toilet.

Safety accidents occur at a rate of about 47.1% in the living room and bedroom, but in fact, if you are with your family, it is possible to minimize the aggravation of the disease caused by the accident by taking prompt follow-up measures. However, in the case of bathrooms including toilets, despite the third rate of 17.3%, there is a high risk of worsening into a major disease because prompt follow-up is not performed.

Therefore, it may be necessary to develop a technology that can contribute to maintaining a healthy lifespan by preventing the elderly from falling in a private space and making quick contact with the outside after an accident.

In other words, the input values of the sensors with high weight in estimating the posture become upper nodes in order and form a tree-structured model while descending sequentially.

For example, a specific time in each situation (e.g., the user entering the bathroom, the user trying to get up from the toilet, the user falling down from the toilet, etc.) The sensor values acquired during the period can be tabulated as shown in FIG. 13 .

Then, when the relationship between the input values of the sensors and the estimated motion (eg, if the distance (measurement) sensor value is greater than 50 and the value of the first force sensor (pressure sensor) is less than 400, the estimated motion is the motion to stand up). After probabilistic calculations for all data, a decision tree as shown in FIG. 14 may be constructed.

That is, the toilet posture assistance and emergency alarm system 100 may predict the user's motion using the motion prediction model constructed as described above (step S350). Therefore, the toilet posture assistance and emergency alarm system 100 may control the system to assist the user's posture by predicting what action the user will take next based on the measured sensing value (step S370).

In addition, the toilet posture assistance and emergency alarm system 100 determines that an emergency has occurred to the user when an abnormal signal is detected from the sensed values collected in the process of assisting the user's posture, and sends an emergency to an external system such as a rescue organization. A rescue may be requested (step S390). In this case, the request for emergency rescue may be implemented and provided in various ways, such as sending an email, generating an alarm sound, and generating a notification message.
