Old people falling detection and protection device based on an acceleration sensor

Abstract

The invention discloses old people falling detection and protection device based on an acceleration sensor and relates to the field of old people falling protection equipment. The falling protection device comprises a detection assembly and a protection assembly, wherein the protection assembly comprises a shoulder protection assembly, an elbow protection assembly, a wrist protection assembly, a waist and crotch protection assembly, a knee protection assembly, a tendon protection assembly and protection air bags installed on the protection assemblies, wherein the protection air bags are inflated by an air generation mechanism, the detection assembly comprises pressure sensors installed in the protection assemblies, an alarm and a control box installed on the waist and crotch protection assembly, and a single-chip microcomputer and an acceleration sensor are installed in the control box. The device is advantaged in that protective assemblies are arranged on portions, prone to fracture,of the old people and are bonded and fixed through hook-and-loop fasteners, wearing is convenient, the contact area with the skin is small, the protective assemblies can be worn in four seasons, falling is detected through the acceleration sensor, a gas generation mechanism is controlled to be started through a Bluetooth module, a protective air bag is inflated, and protection is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the field of fall protection equipment for the elderly, and in particular to an acceleration sensor-based fall detection and protection equipment for the elderly. Background technique [0002] Due to severe decline in muscle strength, lower limb weakness, unsteady gait, osteoporosis, and unresponsiveness, the elderly are prone to fractures. The most prone to fractures after a fall in the elderly are: [0003] 1. Vertebral compression fractures Vertebral compression fractures caused by osteoporosis tend to occur at the junction of the thoracic and lumbar vertebrae, and when they occur frequently, they will cause severe hunchback deformation. The subsequent consequences of vertebral compression fractures include increased chances of future fractures in other parts, chronic back pain, poor quality of life, and even death. Severe or multi-segment vertebral compression fractures require surgery depending on...
