Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an apparatus for preventing fractures such as a hip joint caused by a fall in an elderly person, and more particularly, , And an airbag is attached to the rear of the accelerometer. When the sensor of the accelerometer exceeds the standard set value, it is judged as a fall, and an explosion signal is sent to the detonator of the inflator to inflate the diaper type airbag protecting the hips of the human body.

Description

Portable air bag {Potable safety air bag}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing fracture of a hip joint caused by a fall in an elderly person, When the sensor of the accelerometer exceeds the standard set value, an explosion signal is sent to the detonator of the inflator to inflate the diaper type air bag protecting the hips of the human body.

Fractures and injuries of the hip joint caused by a fall caused by a patient suffering from a disease or an aftermath of illness or from an elderly person are not only difficult to heal the wounds due to the weakness of the body, It can lead to death.

A fall protection device having a buffer space filled with a fluid such as a shock absorbing pad or the like is being developed in order to prevent the injury of the body caused by a fall accident.

As shown in FIG. 1, the fall protection device includes various safety functions including a shock-absorbing function on backpacks carried by the user, so that the user can safely and conveniently use various functions of the backpack, . The safety backpack has a cushioning space filled with a fluid and is worn on the back of the user. The safety backpack is integrally connected to the neck protecting portion provided on the upper side in the longitudinal direction of the back plate and in the longitudinal direction lower portion of the back plate, The first opening and closing part is engaged with the opposite surfaces of the back plate and the hip protecting part to interlock the connection between the back plate and the hip protecting part, and the first opening and closing part is provided on the mutually facing surfaces of the back plate and the backpack detachably attached to the back plate. And a second opening / closing unit coupled to each other for interrupting the connection between the back plate and the backpack.

However, the products using these conventional techniques are not only inconvenient to wear, have a weak body protection function, and are often useless because they fail to properly detect actual fall. Accordingly, there is a demand for a portable air bag which can safely protect against the risk of fracture of the hip joint area and injury caused by a fall accident of a relatively elderly person suffering from a fall of motor nerve and a disease patient, and which is portable and easy to wear.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems of the prior art, and an object of the present invention is to prevent fracture accidents and injuries such as a hip joint caused by a fall accident, And an inflator for inflating a diaper-shaped airbag that protects the buttocks of the human body by an action of an accelerometer which is judged as a fall at the time of falling.

According to an aspect of the present invention, there is provided an acceleration sensor comprising: a belt to be worn on a waist; an accelerometer attached to a front surface of the belt; a sensor for sensing speed and tilt on an inner surface of the accelerometer; And an air bag which expands by an explosion device of the inflator and discharges air to left and right air outlets after occurrence of a fall accident.

The portable air bag including the belt, the accelerometer, the sensor, and the airbag according to the present invention senses the fall only when the human body falls, such as the elderly and the sick person, It can be more safely protected from the risk of fractures and injuries, and is easy to carry and wear.

Hereinafter, a portable air bag for preventing a fracture accident and injuries of a hip joint caused by a fall accident occurring in a patient suffering from the disease of the present invention or a patient suffering from a mobility disorder due to a sequela of a disease, or an elderly person, The following is an explanation.

1 is a view showing a state in which a safety backpack having a buffer space filled with a conventional fluid is worn.

2 is a view showing a front view of a portable airbag according to the present invention.

Fig. 3 is a rear view of the portable airbag according to the present invention.

4 is a view showing an operation of the portable airbag according to the present invention.

The portable airbag for preventing a hip joint fracture accident and injury caused by a fall accident occurring in a patient who is uncomfortable due to the aftermath of the disease of the preferred embodiment of the present invention or an elderly person is as shown in Figs. 2 and 3 An accelerometer 102 is attached to the front surface of the belt 101 worn on the waist based on the inflator technology of the accelerometer 102 and the airbag 104. An accelerometer 102 is attached to the front surface of the belt 101, (Not shown).

The accelerometer 102 is provided with a sensor 103 for sensing the speed and inclination of the body in front, back, up, down, left, right, and three axes (x, y, z) The sensor 103 incorporated in the airbag device 104 determines that the airbag 104 is falling when the airbag 104 exceeds the standard set value and sends an explosion signal to the detonator of the inflator through the electric wire 105 to protect the hip portion of the human body To expand.

It is possible to reuse the airbag 104 by discharging air through the left and right air outlets of the airbag 104 after the fall prevention. The inflator and detonator are configurations known and used in common airbags.

As a result, the portable airbag of the present invention can safely protect against the risk of fracture and injury of the human body, and can easily and conveniently be worn on the waist.
