Description

[0001] The present invention relates to a system for managing patients and senior citizens using a pressure sensor,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a patient and a geriatric care system using a pressure sensor, and more particularly, to a patient and a geriatric care system using a pressure sensor, The present invention relates to a management system for a patient and an elderly person using a sensor.

The problem of the elderly in modern society has many problems due to rapid change of society. It is common to go to a hospital for nursing care, and even though a nursing hospital is called modern-day hospital, it has become a irrevocable social phenomenon in the social phenomenon that is driven by the nuclear family.

In this hospital management system, patients or guardians should be able to safely care for the fall accidents of the elderly people.

The reason for the frequent fall of the patient or elderly people in the hospital is that they can not move to the bathroom by themselves because of the inconvenience, but they do not call the night watchdog after sleep and fall down when they go down the bed. Patients and elderly people with low energy are often exposed to death.

In other words, in the case of the elderly, there are many cases in which they do not press a separate call-up call to call a nurse or a nurse, and accidents are frequent. This may result from the fact that the education effect is insignificant for an aged old person.

Conventional techniques for solving such problems include installing a call bell on a bed of a subject so that the subjects can call the manager and prevent the elderly who do not have energy from falling into a struggle at bedtime, There is a device that fixes hands and feet with a fixed gear and a railing on the bed.

However, since the conventional techniques are based on the active call of the patient or the elderly, the method of making the judgment disadvantageous becomes useless and the method of arbitrarily making the behavior uncomfortable, even when the movement is necessary, There are limitations that can be caused.
