Description

A kind of upper limb pronation deformity orthosis

technical field

The invention belongs to the field of medical devices, in particular to an orthosis for upper limb pronation.

Background technique

The forearm has pronation deformity, and the inability to supinate is the clinical manifestation of radial nerve injury in sports. The radial nerve is close to the bone in the middle and lower third of the humerus, where the radial nerve is vulnerable to injury when the humerus is fractured. Excessive callus growth and anterior dislocation of the radial head can compress the radial nerve. Inadvertent surgery can also injure this nerve. When the radial nerve of the upper arm is injured, the extensor muscles are extensively paralyzed. Both were paralyzed. Therefore, the wrist sags, the thumb and fingers sag, and the metacarpophalangeal joints cannot be extended. These conditions limit the range of motion of the joint.

Often this condition can be treated with range of motion (ROM) orthoses for relief. ROM orthoses are devices commonly used during physical rehabilitation therapy to increase the range of motion of the wearer's movable joints. However, most of the existing ROM orthoses have the problems of complex operation and many control joints, so that they affect daily life.

Contents of the invention

One of the purposes of the present invention is to address the deficiencies in the prior art, to design an upper limb pronation orthosis, which can keep the patient's upper limbs at the normal position in front of the chest, effectively improve the patient's upper limb deformity and have Easy to operate and control the characteristics of less joints.

The invention provides an orthosis for upper limb pronation, comprising a belt body made of elastic fiber, a forearm correction sleeve, a hand correction sleeve and elbow connectors; the belt body made of elastic fiber includes a waist elastic belt , shoulder elastic band and fixed elastic band, described for fixing the elbow connector of forearm correction sleeve and hand correction sleeve is positioned between waist elastic band; Described shoulder elastic band one end is fixed on the forearm correction sleeve, another One end fastens to the waist elastic band.

Further, the hand correction set includes a palm correction set and a thumb correction set.

Further, the forearm correction sleeve, palm correction sleeve and thumb correction sleeve are respectively positioned and fixed by fixing elastic bands.

Further, the waist elastic belt and the shoulder elastic belt are provided with a plurality of hoops, Velcro belts and fixing fasteners for connecting the belt bodies.

Further, the fixed elastic band is provided with a Velcro for fixing.

Further, the forearm correction sleeve is provided with an iron ring, a Velcro belt and a fixing fastener for connecting with the shoulder elastic band toward the elbow.

Further, there are two waist elastic bands, one shoulder elastic band, and at least three fixed elastic bands.

Further, the forearm correction sleeve, palm correction sleeve and thumb correction sleeve can be used as a whole or can be split and combined for use.

The invention is mainly used for internal rotation and extension of the shoulder joint, straightening of the elbow joint, pronation of the forearm, flexion of the wrist joint, adduction of the thumb, fist clenching and the like after brain injury. The purpose of using the present invention is to keep the upper limb of the affected side externally rotating the shoulder joint, flexing the elbow joint, supinating the forearm, dorsiflexing the wrist joint, abducting the thumb, straightening the five fingers, relieving muscle tension, increasing the range of motion of the joint, preventing Joint contractures.

The beneficial effect of the present invention is that: the present invention connects the forearm orthotic sleeve and the hand orthotic sleeve with the belt made of elastic fiber, which can achieve two effects: one is to keep the patient’s upper limbs in the supinated position of the chest, effectively improving the patient’s upper limbs. The second is that it is easy to use, easy to put on and take off, has few joints to control, and has no hindrance to daily life.
