WHEELCHAIR SAFETY MELODY APPARATUS

Abstract

The invention is related to a wheelchair safety melody apparatus, which comprising: a wheelchair, including a seat pad; at least one handrail, fixed to the wheelchair; a pressure-sensitive seat pad, placed above the seat pad; and a safety melody generator, electrically connected with the pressure-sensitive seat pad, and being removably fixed at one side of the at least one handrail via a fastening element, wherein as a user leaves the seat of the wheelchair, the pressure-sensitive seat pad generates an initiating signal due to release of the pressure of the pressure-sensitive seat pad, thereby to allow the safety melody generator to generate an alarm signal for notifying a medical care person for assistance.

Claims

EMBODIMENTS OF THE INVENTION

[0014] As shown in FIG. 1, a wheelchair safety melody apparatus 100 according to the invention comprises:

a wheelchair 110, including a seat pad 111;
at least one handrail 120, fixed to the wheelchair 110;
a pressure-sensitive seat pad 130, placed above the seat pad 111 of the wheelchair 110;
and
a safety melody generator 140, electrically connected with the pressure-sensitive seat pad 130, and being removably fixed at one side of the at least one handrail 120 via a fastening element 150,
wherein as a user leaves the seat of the wheelchair, the pressure-sensitive seat pad generates an initiating signal due to release of the pressure of the pressure-sensitive seat pad, thereby to allow the safety melody generator to generate an alarm signal for notifying a medical care person.

[0015] It is noted that the leaving of the user from the seat of the wheelchair is that the user is standing or sliding off from the wheelchair.

[0016] In the wheelchair safety melody apparatus 100 of the invention, the alarm signal is a musical melody or other alarming sound.

[0017] According to the wheelchair safety melody apparatus of the invention 100, the safety melody generator 140 and the pressure-sensitive seat pad 130 are electrically connected through a connection wire 160, in which a middle part of the connection wire is mutually engaged via a male connector and a female connector of a telephone wire (not shown in the drawing) to facilitate free movement of the wheelchair.

[0018] As shown in FIG. 2, in the wheelchair safety melody apparatus100 of the invention, the safety melody generator 140 includes: an alarm signal exit 141 for emitting the alarm signal; an alarm signal stop button 142 for shutting down the alarm signal; an emergency button 143 for emitting the alarm signal upon pressing so as to inform the medical care person for assistance; a power indicator 144 for generating a light indicating after power-on, and a power switch 145.

[0019] In addition, the safety melody generator 140 further includes a volume control switch 146, and a power source (not shown in the drawing) which is a battery to facilitate movement of the wheelchair.

[0020] In the wheelchair safety melody apparatus 100, the fastening element 150 is a Velcro tape or a fastening component with male and female engaging function (not shown in the drawing).
