Embodiments of the present disclosure relate to an upper limb stabilizing apparatus.
When a patient with upper limb (arm) paralysis uses a wheelchair, a lab board is generally mounted on the wheelchair to be used. Here, the arm paralysis patient using the lab board lives with the paralyzed arm in a forearm pronation posture.
Muscle tension of the paralyzed arm is increased and over time, the paralyzed arm is deformed to the pronation posture and joint contracture occurs. The pronation posture on the lab board may be a posture that promotes such a negative deformation. Accordingly, it is necessary to encourage the arm paralysis patient to change a posture of placing the arm on the lab board from the pronation posture to a supination posture that is a posture opposite to the pronation posture.
Also, in an arm paralysis patient, deformation or contracture occurs in a flexion posture, and when the pronation posture of the arm paralysis patient is maintained, this induces deformation or contracture.
In order to solve above-described problems, the present disclosure provides an upper limb stabilizing apparatus assisting an upper limb paralysis patient to live with the forearm maintaining a supination posture on a lab board.
However, such problems are examples and problems to be solved in the present disclosure are not limited thereto.
An upper limb stabilizing apparatus according to an embodiment of the present disclosure includes: an arm resting portion where an arm is rested; an arm fixing portion where the rested arm is fixed; a hand resting portion connected to the arm resting portion and where a hand is rested; a hand fixing portion where the rested hand is fixed; and a Velcro portion arranged at the arm fixing portion and the hand fixing portion to attach or detach the arm fixing portion and the arm resting portion, and the hand fixing portion and the hand resting portion, respectively, to or from each other.
In the upper limb stabilizing apparatus according to an embodiment of the present disclosure, the arm resting portion may be formed of soft memory foam.
In the upper limb stabilizing apparatus according to an embodiment of the present disclosure, the arm resting portion may include a medial epicondyle resting portion and a styloid process resting portion, wherein sponginess of the medial epicondyle resting portion and the styloid process resting portion may be greater than sponginess of a remaining portion of the arm resting portion.

Referring to
An outer forearm part may be rested in the arm resting portion 100. The arm resting portion 100 may be formed in a cylindrical shape. When the arm resting portion 100 is formed in the cylindrical shape, the arm rested in the arm resting portion 100 having the cylindrical shape maintains a supination posture of being supinated only by 45° instead of by 180° by a cylindrical surface, and thus, a patient maintains the supination posture, in which a hand is turned at a certain angle, so as to feel comfortable when the arm is fixed.
Also, the arm resting portion 100 is a portion where the arm is rested, and thus may be formed of a soft memory foam material. When the arm resting portion 100 is formed of a soft memory foam material, a bedsore and a wound, which may occur when the arm is fixed for a long period of time, may be prevented.

Referring to
The protruding arm fixing portions 200 may fix the arm as the arm fixing portions 200 surround the arm rested in the arm resting portion 100 while Velcro portions 540 and 550 arranged at ends of the arm fixing portion 200 are attached and fixed to one surface portion of the arm resting portion 100.
Here, the Velcro portions 540 and 550 may adjust attached positions to the arm resting portion 100 thereby varying a fixing degree of the arm according to the condition of the arm, such as the size, fixing position, or the like of the patient's arm.
According to an embodiment of the present disclosure, the arm fixing portion 200 may be formed as a net. Accordingly, a breathable structure may be formed such that the patient's arm fixed through the arm fixing portion 200 is ventilated. Accordingly, a bedsore and a wound, which may occur in the patient's arm and hand due to long-term fixation, may be prevented.
Referring to
Here, the Velcro portions 560 and 570 may adjust attached positions to the hand resting portion 300 thereby varying a fixing degree of the hand according to a condition of the hand, such as the size, fixing position, or the like of the patient's hand.
The hand resting portion 300 is a portion where the hand is rested, and thus may be formed of a soft memory foam material. When the hand resting portion 300 is formed of a soft memory foam material, a bedsore and a wound, which may occur when the hand is fixed for a long period of time, may be prevented.
The hand fixing portion 400 may be attached to the hand resting portion 300 through a Velcro portion 530. Here, the Velcro portion 530 may adjust an attached position to the hand resting portion 300, thereby varying the fixing degree of the arm according to the condition of the patient's arm.
According to an embodiment of the present disclosure, the hand fixing portion 400 may be formed as a net. Accordingly, a breathable structure may be formed such that the patient's arm fixed through the hand fixing portion 400 is ventilated.
Referring to
Referring to
After the hand and the arm are rested on the upper limb stabilizing apparatus, the arm fixing portion 200 and the hand fixing portion 400 are rolled up to be attached to the lab board B and the hand resting portion perpendicular surface portion 300a, as shown in
Hereinafter, first, second and third angles according to an embodiment of the present disclosure will be described with reference to
Referring to
The first angle a1 formed by the arm resting portion 100 and the hand resting portion 300 may be adjusted. The first angle a1 formed by the arm resting portion 100 and the hand resting portion 300 may be adjusted according to angles at which a user's hand and arm are rested and shapes of the user's arm and hand. For example, an angle between the arm resting portion 100 and the hand resting portion 300 may be adjusted to 0 degree, to 15 degrees according to an embodiment, or up to 30 degrees according to circumstances. Here, the angle may be adjusted by adjusting an attached angle of the hand resting portion 300 to the arm resting portion 100.
The hand resting portion 300 may be detached from the arm resting portion 100. When the patient uses a wrist prosthesis, the hand resting portion 300 may be removed from the arm resting portion 100 and then the arm may be fixed by using only the arm resting portion 100.
In addition, the hand fixing portion 400 may be detached from the hand resting portion 300. Accordingly, the patient's arm may be fixed by using only the hand resting portion 300 and the arm resting portion 100.
Referring to
Accordingly, when the hand resting portion 300 is formed in the triangular prism shape, the hand rested on the hand resting portion 300 having the triangular prism shape is not completely supinated to the supination posture but maintains being supinated only by about 45 degrees by a triangular prism surface, and thus, the patient may feel comfortable with the fixed hand and arm compared to when the hand and arm are completely supinated.
The hand resting portion 300 is formed in the triangular prism shape and the arm resting portion 100 is formed in a cylindrical shape, and thus, a connecting portion of the hand resting portion 300 and the arm resting portion 100 may have a twisted shape.
