Limb joint functional position keeping device

Abstract

The invention discloses a limb joint functional position keeping device which is formed based on novel ventilating materials, can effectively keep limbs in whole body to functional positions, effectively prevents joint deformity and is beneficial to functional recovery. The limb joint functional position keeping device is widely suitable for keeping functional positions of various joints of coma patients and paralysis limbs, and is beneficial to the recovery of the joint and limb motion functions of the patients, such as hemiplegia, cerebral palsy, infantile cerebral palsy, paraplegia and the like caused by central nervous system and bone joint muscle injuries. The limb joint functional position keeping device is made of a polymer fiber orthopedic instrument material; and a positive plaster model comprising a main body, a fixing belt and a sponge sheet is made according to shapes of limb joint parts of average persons with different age groups and postures. A series of keeping devices are formed according to the figure in accordance with functional positions of various joints in whole body, including shoulders, elbows, wrists, hips, knees and ankle joints, and a limb joint functional position keeping device for a special body can be singly made. The limb joint functional position keeping device has the advantages of ventilation and sweat absorption, X-ray transmission, fragrant smell, light mass, easiness in formation, convenience for wearing, and capability of being used for inpatient areas and individuals.

Description

technical field [0001] The invention relates to a holding device, in particular to a medical joint holding device. Background technique [0002] Clinically, limbs after coma, central nervous injury, hemiplegia, quadriplegia and paraplegia, due to loss of autonomic innervation, inability to move voluntarily, muscle paralysis and lack of tension, often lead to abnormal posture of limbs, such as foot drop inversion, knee joint hyperextension, Elbow, wrist flexion, etc. If the limbs are slightly longer in the above positions, it will lead to adhesion and contracture of the corresponding muscles (antagonist muscles) and tendons, which will lead to joint deformities. Studies have shown that if the shoulder joint of a normal person is fixed with plaster for 1 day, it takes 7 days to loosen the adhesion caused by the static muscles and soft tissues. If it is fixed for 3 weeks, it takes about 300 days to loosen the resulting adhesion. If the fixation time is longer, it will be diff...

AI Technical Summary

Problems solved by technology

In addition to the insufficient effect of these items on preventing joint deformities, bedridden patients need to turn over frequently (at least once every 2 hours), and the patient's position needs to be repositioned, which is more cumbersome and is not used.

Therefore, the awareness of maintaining the functional position of joints is still very indifferent clinically, and there are no special appliances, equipment and devices, and it is basically in a blank state.
