Description

Foot fixing support for preventing foot drop and heel pressure sore of bedridden patient

Technical Field

The utility model relates to a foot fixer, in particular to a foot fixing support for preventing foot drop and heel pressure sore of a bedridden patient, and belongs to the technical field of medical auxiliary appliances.

Background

The lower limb of a patient who needs to lie in bed for a long time due to spinal cord injury, stroke, hemiplegia, craniocerebral injury, late poliomyelitis and other diseases leads to long-term compression of parts such as common peroneal nerve, plantar nerve, sciatic nerve, lumbosacral nerve root and the like, easily leads to foot drop complications and seriously influences the later standing and walking functions of the patient. In addition, the patients are bedridden for a long time to cause the heel to be pressed intensively due to the feeble lower limb paralysis, and heel pressure sores are easy to occur. Therefore, when the bedridden patient is rehabilitated and nursed, the lower limbs of the patient need to be lifted, the blood circulation of the lower limbs is promoted, meanwhile, the feet and the lower legs of the patient are kept at 90-degree functional positions, and the pressure at the heels of the feet is relieved, so that the foot drop and the heel pressure sores are prevented from happening. At present, the general clinical practice is to place soft pillows or bedding for padding at the positions of feet, lower legs and the like of patients, and because the soft pillows or bedding have poor shaping force and are easy to deform, the soft pillows or bedding need to be checked and adjusted frequently, and therefore, special foot drop prevention protectors are worn on the lower limbs of the patients in some hospitals. However, the existing foot drop prevention protector often has the following defects:

(1) and the design structure of part of the protective tool is complex, the use steps are complex, and the operation and the regulation are inconvenient.

(2) Partial protective equipment can't adjust to different patient's foot size, needs customize according to patient's foot size, therefore the waiting period is long, economic cost is higher.

(3) The heel can be wrapped after the use of partial protective equipment, the original buffering to the heel pillow is invalid, and protective equipment itself lacks sufficient prevention heel and presses sore function again, leads to losing one another.
