Description

NOTIFICATION SYSTEM OF RISK ON WHEELCHAIR USER

The present invention relates to a risk notification system for wheelchair users, and more specifically, to a risk notification system for wheelchair users that enables wheelchair users, such as disabled people or patients suffering from temporary accidents, to quickly notify those around them of an accident situation that may occur when using a wheelchair.

People with disabilities or patients suffering from temporary accidents may use wheelchairs.

Wheelchairs are divided into two types: the common manual wheelchair, which operates the wheels with the arms, and the electric wheelchair, which operates the wheels with a motor.

In the case of electric wheelchairs, the discomfort for the user is reduced compared to manual wheelchairs, but there is still a risk of accidents in which the wheelchair may collide with other objects or fall sideways.

In addition, conventional wheelchairs have the problem that it is difficult for wheelchair users to notify others of emergency situations such as shortness of breath, and if a wheelchair user experiences cardiac arrest, it is difficult for them to effectively notify others of the dangerous situation.

The prior art is technical information that the inventor possessed for the purpose of deriving the present invention or acquired in the process of deriving the present invention, and cannot necessarily be said to be a publicly known technology disclosed to the general public prior to the application for the present invention.

Republic of Korea Patent Publication No. 10-1574076 (Registered on November 27, 2015)

The cover part (20) can be installed on the body part (10) with a structure that rotates around a hinge axis, and a locking function can be provided by various means (e.g., a magnet).

The cover part (20) may have a window part (22) in the central opening, and may have a mounting part (21) adjacent to the window part (22) on a surface facing the inside of the body part (10) when closed. The mounting part (21) forms a structure in which the display part (180) is fitted in a sliding manner. The window part (22) allows the display part (180) to be visually recognized from the outside even in the closed state of the cover part (20) when the display part (180) is fitted into the mounting part (21) and used.

As described above, the risk notification system for wheelchair users according to the present invention enables wheelchair users, such as disabled people or patients suffering from temporary accidents, to quickly notify those around them of an accident situation that may occur when using a wheelchair, and at the same time significantly reduces the possibility of malfunction of the device.
