Abstract

The utility model relates to an automatic lower limb recovery chair. The utility model is used for paralytic limbs of patients with paralytic lower feet caused by cerebrovascular disease and trauma to early do arc movement, and is used for preventing muscular atrophy and joint ankylosis and recovering traveling functions of lower limbs. The upper part of a chair base is provided with an electric motor, a driving belt, a belt wheel, a speed variator, an eccentric wheel, a connecting rod, etc. The front edge of a chair seat plate is provided with swinging foot frames, etc. The utility model uses the electric motor as power, utilizes the driving belt, the belt wheel, the speed variator, the eccentric wheel and the connecting rod to automatically control the foot frames to swing, and drives the paralytic limbs to do arc reciprocating motion. Thus, the utility model prevents muscular atrophy and joint ankylosis and recovers the traveling function of the lower limbs.

Description

Automatic lower limb restoration chair

This utility model belongs to a kind of medical rehabilitation apparatus, and particularly a kind of lower extremity paralysis patient who is used for due to cerebrovascular, the wound forces the paralysis limb to make the automatic lower limb rehabilitation chair of 45 ° of arcuate movement.

At present, the medical apparatus and instruments that is used for the treatment of rehabilitation paralysis limb is very few, has that electronic rollover body is functional nursing bed, a multi-functional paralysis therapy apparatus of YL-I type etc.Prove the principle of " moving back " with advancing to give up according to upright walking physiological function of the mankind and clinical practice.If paralysis limb inertia half a year, then amyotrophy, ankylosis are lost the function that walks upright, if can adhere to motion, just can prevent amyotrophy, ankylosis, just can recover the lower limb walking function.The above apparatus though be suitable for the heavy patient that lies in bed, is made the lower limb passive activity, effect is better in early days, for can sit, upright convalescent, help paralysis limb movement effects relatively poor.And its complex structure, cost an arm and a leg, be not suitable for patient in family and use, be difficult to promote.

The purpose of this utility model just provides automatic lower limb rehabilitation chair a kind of simple in structure, cheap, satisfactory for result.

Task of the present utility model is finished in the following way: in chair base one side motor is housed, another side is equipped with variator, in the variator inboard eccentric, connecting rod etc. is housed, and in chair seat forward position the swing foot rest is housed.With the motor is power.By driving-belt and belt wheel, be transferred to variator, drive eccentric, promote the swing foot rest through connecting rod, drive 45 ° of arcs of paralysis limb work and move back and forth, to prevent amyotrophy, ankylosis, recover the lower limb walking function.

Below in conjunction with accompanying drawing this utility model is described in further detail.

Accompanying drawing is this utility model structural representation.

Automatically the lower limb rehabilitation chair mainly is by chair (8), motor (5), variator (3), eccentric (4), connecting rod (2), swing foot rest formations such as (1).

Side at the base (7) of chair (8) is equipped with motor (5).Opposite side at base (7) is equipped with variator (3), is equipped with on eccentric (4), the eccentric (4) in the inboard of variator (8) connecting rod (2) is housed, on chair (8) seat forward position, swing foot rest (1) is housed, and swing foot rest (1) links to each other with eccentric (4) by connecting rod (2).Variator (3) links to each other with motor (5) by drive pulley (6).

During use, energized at first, motor (5) rotates, by driving-belt and belt wheel (6).Power is transferred to variator (3), drives eccentric (4) by variator (3) again and rotate,, promote 45 ° of arcs of swing foot rest (1) work and move back and forth through connecting rod (2).Like this, patient is sitting on the chair (8), and the paralysis limb is fixed on the swing foot rest (1), is forced to do 45 ° of arcs and moves back and forth, thereby prevent amyotrophy, ankylosis, recovers paralysis limb walking function.

This utility model be suitable for family, hospital can sit, upright and paralytic that can not independent ambulation is used to help the continuous motion lower limb of patient, recover walking function, so that the heavy nursing work of liberation.

Claims

1, a kind of automatic lower limb rehabilitation chair, it is characterized in that motor (5) being housed in a side of the base (7) of chair (8), opposite side at base (7) is equipped with variator (3), eccentric (4) is equipped with in variator (3) inboard, swing foot rest (1) is housed in chair (8) seat forward position, and swing foot rest (1) connects by the connecting rod (2) that is fixed on the eccentric (4).
