Patient is using left and right two while turning frame, with left and right axillary fossa, clamp respectively left and right axillary fossa holder, by left hand and right hand, hold left and right handle, patient should be supported on body wt on handle by hands as best one can, axillary fossa is clipped in axillary fossa holder as supplemental support, crutches are shifted to suitable distance before health simultaneously, under the condition supporting at crutches, step forward Ipsilateral lower limb, the heel of Ipsilateral lower limb first lands, and then whole sole lands, then steps forward strong side lower limb, and surpass the suitable distance of Ipsilateral lower limb, complete street one step.

In prior art, the frame foot that turns of the lower end of vertical rod is the rubber antiskid cover that is enclosed within the lower end of vertical rod.To turn frame be independently to left and right two of this crutches, when walking, the both feet that turn frame foot and patient of the crutches floor-type support of alternately taking a step successively, needing patient to have a side lower limb is healthy lower limb, to the patient of some two lower limb weakness and upper limb also weak patient, special upper limb and lower limb are weaker gerontal patient all, and above-mentioned crutches are not well suited for.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes a kind of be applicable to two patients of lower limb weakness and the patient of upper limb weakness, special upper limb and the lower limb capable crutches chair of wheel that all weaker gerontal patient uses.

This utility model is realized with the following method.

Wheel row crutches chair has a left side, right two are turned frame, turn frame and have vertical rod, there is axillary fossa holder the upper end of vertical rod, vertical rod has parallel upper pright stanchion and lower vertical rod, lower vertical rod is expansion link, expansion link has inner and outer tubes, upper pright stanchion is hinged on the upper end of inner tube with screw rod securing member, axillary fossa holder is in the upper end of upper pright stanchion, there is hands handle the lower end of upper pright stanchion, there is radially nut frame the side of outer tube, the fastening bolt that has inner tube on nut frame, between fastening bolt and inner tube, there is rubber blanket, the outer tube lower end of lower vertical rod is connected with the longeron vertical with vertical rod, before the below of longeron has, rear travelling wheel, left, the rear end of right two longerons is connected with sill, a left side for crossbeam, between the lower vertical rod of right both sides and corresponding side, be connected with pull bar, between lower vertical rod and its longeron, be connected with chair frame, there is pin chair frame top, the rear side of the outer tube upper end of lower vertical rod is connected with radial arm, there is the jack parallel with lower vertical rod radial arm back, in jack, be inserted with inserted link, there is pin in the place ahead of inserted link, left, between the rear of right inserted link, be connected with two parallel back crossbeams, left, on the pin in right inserted link the place ahead, be connected with the horizontal backup plate with pin-and-hole.

While using this utility model, with left and right axillary fossa, clamp respectively left and right axillary fossa holder, by left hand and right hand, hold left and right handle, both feet fall on the ground, patient should be supported on body wt on handle by hands as best one can, axillary fossa is clipped in axillary fossa holder as supplemental support, with foot, steps backward ground, can drive this utility model travelling wheel to rotate walking forward.When walking, though two lower limb of patient all softer a little less than, within the short time of the whole built on stilts of both feet, can not fall with this utility model body support yet; For the upper limb also patient of weakness, special upper limb and lower limb are weaker gerontal patient all, in use, backup plate can be taken off from the pin in left and right inserted link the place ahead, backup plate is placed in the chair frame between left and right lower vertical rod and its longeron, the pin-and-hole of backup plate is enclosed within on the pin of chair frame top, become seat, patient can be sitting on seat, steps backward ground and drives this utility model to walk forward, or promote walking with others with foot.

It is the parallel upper pright stanchion being hinged and connected and lower vertical rod that this utility model turns frame vertical rod, lower vertical rod is expansion link, can be applicable to the patient that height is different uses, there is travelling wheel the lower end that this utility model turns frame, on the left and right inserted link that lower vertical rod rear is connected with, be connected with horizontal backup plate, can take off in the chair frame being placed between left and right lower vertical rod and its longeron, become seat.This utility model is applicable to two patients of lower limb weakness and the patient of upper limb weakness, and special upper limb and lower limb all weaker gerontal patient are used.

Below in conjunction with accompanying drawing, the utility model is further described.
