Description

Orthopedic nursing walking aid

Technical Field

The invention belongs to the technical field of walking aids, and particularly relates to an orthopedic nursing walking aid.

Background

Fracture healing is a relatively long process, after lower limb fracture, even if the lower limb fracture can heal smoothly, long-term rehabilitation training is needed, the early-stage rehabilitation training generally starts from adapting to load, and at present, the early-stage rehabilitation training of lower limb fracture generally uses a walking aid to carry out walking training, so that a patient with lower limb muscle weakness supports the weight of the body by arms, thus standing and walking can be avoided, improper load of the patient with legs can be avoided, the mobility of the patient is increased, and muscle atrophy is avoided.

The conventional walking aids are a hand-push type walking aid and a crutch respectively, the hand-push type walking aid is generally classified according to the presence or absence of rollers, a patient is required to lift the walking aid by the aid without the wheel type walking aid, then the walking aid is moved forwards, the burden on the patient is large, secondary injury can be possibly caused in rehabilitation training, the wheel type walking aid only needs to be pushed forwards by the patient, the patient does not need to lift the walking aid, the burden of the patient is lightened, but the burden carried by the lower limb of the walking aid is small, the exercise effect can be influenced at the later stage of rehabilitation training, meanwhile, the hand-push type walking aid is generally large in size and difficult to pass through places with large people flow and narrow places; the walking stick has poor walking aid effect, and the risk of using in rehabilitation training is larger, but the walking stick has small volume and light weight, is more flexible to use, can be used as a support after the muscle is tired for a patient with higher recovery degree, and avoids the problem that the patient cannot find a rest position and loads the leg for a long time, so the walking stick can be used as the walking stick, and can be used as an orthopedic nursing walker for a hand-push type walker.
