After degree, buzzer sends alarm, reminds patient to reach the training angle of setting, prevents over training from causing secondary damage.
Further, the forearm supports supporting plate and postbrachium to support supporting plate inner surface setting to have air bag liner, for making patient
Limbs support supporting plate and postbrachium to support supporting plate to be in close contact with forearm, reduce secondary injury.
Further, supporting plate and postbrachium is supported to support deck internal to be provided with pressure sensor in forearm, pressure sensor connects
Display or alarm device are connected to, when the pressure that patient applies is excessive, the display is used to point out patient pressure excessive, needs
Reducing pressure prevents secondary injury；The alarm device is used to send alarm when pressure is excessive, prevents patient from applying pressure mistake
Secondary injury is caused greatly.
During the device use, limbs are positioned over forearm and support supporting plate and postbrachium to support on supporting plate by patient, Ran Houshe
Put and train angle, and adjust forearm support supporting plate, postbrachium support supporting plate on forearm supporting guide and postbrachium supporting guide
Position, realize to limbs of patient optimum laminating.Another hand rotates driving handle, and by horizontal drive shaft vertically cone is driven
Pinion rotation, vertical bevel gear driving horizontal bevel gear is rotated, and horizontal bevel gear drives vertical ball screw to rotate, rotation it is perpendicular
Straight ball screw drives the ball screw nut on vertical ball screw to move upwards.The ball screw nut for moving upwards drives
The forearm pushing mechanism and postbrachium pushing mechanism of ball screw nut both sides is moved upwards, so that arm-supporting splint support beam is with after
Arm blaster support beam is relatively rotated, so as to drive arm before and after supporting guide and arm before and after supporting bracket on arm before and after pallet support beam
Plate is relatively rotated, so as to realize that arm before and after supports the limbs of patient stretching on supporting plate.When limbs are stretched to the training angle of setting
When, buzzer warning, patient rotates backward driving handle, realizes the bending training of limbs, when limbs of patient is bent to setting
During training angle, buzzer warning, patient carries out again stretching training, constantly repeatedly aforesaid operations, realizes the rehabilitation instruction in joint
Practice.
The respective embodiments described above are to realize the specific embodiment of the present invention, it will be understood by those skilled in the art that
And in actual applications, can in the form and details to it, various changes can be made, without departing from the spirit and scope of the present invention.
