Abstract

PURPOSE: A portable, fracture preventing system is provided to protect elderly people or the handicapped from fracture when they accidently fall or collapse on the ground, by absorbing shock. CONSTITUTION: The portable, fracture preventing system includes a sensor(1), a controller(4), an air bag module(5), and a battery(6). The sensor(1) includes an acceleration sensor(2) and an angle sensor(3). The controller(4) includes a microprocessor for analyzing detected signals and performing appropriate processes. The angle sensor(3) detects limit of stability on both sides of a user and transmits it to the controller(4). When the user is about to fall, the controller(4) sends a signal to the air bag module(5), and the air bag instantly inflates for buffing the body from the ground.

Description

Portable Bone Fracture Prevention System

The present invention relates to a portable fracture prevention system, in order to prevent fractures of the cuff bones and hip bones that commonly occur when the body loses balance due to a fall in the balance function or an obstacle of an elderly person or a disabled person. It is a technology that prevents fractures by attaching an electronic portable fracture prevention system. Conventionally, there is no electronic method for preventing fractures, and there is a degree of inserting a shock absorbing material into the clothes just around the hips, which is inconvenient to wear, and especially in summer, such clothes cannot be worn. It is also thought that there is no special system for preventing cuffs.

As described above, in order to prevent fractures that occur when the elderly or the disabled fall down, the angle and the momentary acceleration of the portable fracture prevention system having the angle and acceleration sensor and the airbag module built into the body of the elderly or the disabled It is to provide a portable fracture prevention system that prevents fracture by sensing and calculating the moment, by inflating the airbag in the fracture possible area and buffering between the ground and the body.

In order to achieve the above object, the portable fracture prevention system provided in the present invention includes an angle sensor and an acceleration sensor for detecting a fall of an elderly person or a disabled person, a control unit for analyzing and processing signals detected from the angle and acceleration sensor, and the control unit. Air bag module that is instantaneously inflated by the signal from the hand wraps around the cuffs or hips, the power supply for supplying power to each of the parts, the portable unit, characterized in that the built-in each part can be attached to the waist or cuff A fracture prevention system.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a portable fracture prevention system of the present invention, Figure 2 is a block diagram of a portable fracture prevention system for attachment to the wrist of the present invention, Figure 3 is an illustration of an embodiment of the present invention.

The portable fracture prevention system provided by the present invention shown in FIG. 1 includes a detection unit 1 including an acceleration sensor 2 and an angle sensor 3 for detecting a fall of the elderly, and a detection unit detected by the detection unit. The controller 4 includes a microprocessor for analyzing and processing signals, an airbag module 5 which is inflated instantaneously by a signal processed by the controller, and a power supply unit for supplying power to each part. The portable fracture prevention system detects the front and rear left and right LOS (Limit of Stability) value of the elderly by the angle sensor (3) when the elderly person falls, and at the same time by detecting the acceleration value in the front, rear, left and right directions by the acceleration sensor (2) When passed to the control unit 4, the microprocessor in the control unit 4 gives a signal to the airbag module (5) informing the phenomenon of falling compared to the normal life behavior pattern, the airbag is instantaneously inflated and between the body and the ground It acts as a buffer to prevent fractures.

In the wrist-type portable fracture prevention system of the present invention shown in FIG. 2, the method of inflating the airbag by detecting the fall is the same as the above method. However, when the angle sensor (3) and the acceleration sensor (2) is placed on the wrist, it is difficult to accurately detect the falling phenomenon because the wrist moves in various directions, and it is inconvenient to wear because the weight becomes heavy and bulky. Therefore, the part including the sensing unit 1 and the control unit 4 and the wireless transmitter 7 for transmitting the value determined by the control unit to the airbag module 5 attached to the cuff are separated and attached to the waist. The receiver 8 and the airbag module 5 which receive the value transmitted from the radio transmitter 7 are attached to the wrist part.

On the other hand, Figure 3 is an exemplary view of such an embodiment of the present invention, Figure 3 (a) shows an example inflated to wrap the airbag around the hips when the elderly fall down, Figure 3 (b) is an airbag It is inflated to wrap around this cuff.

The present invention can eliminate the cause of the cuff bones and hip bones fall down and fall down when the balance falls due to the deterioration of the balance function or obstacles that occur most often to the elderly or the disabled, and every year in national fractures of the elderly This will greatly reduce the cost of treatment. In addition, the portable form is attached to other parts of the body, there is an effect that can protect a part of the body in inadvertent fall accident or traffic accident in mountain climbing. In addition, it can contribute greatly to the development of the underdeveloped silver industry and securing international competitiveness in this field.
