Description

TECHNICAL FIELD Embodiments of the present disclosure relate to an upper limb stabilizing apparatus. BACKGROUND ART 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. DISCLOSURE Technical Problem 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. Technical Solution 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. In the upper limb stabilizing apparatus according to an embodiment of the present disclosure, attached positions of the arm fixing portion and the arm resting portion, and the hand fixing portion and the hand resting portion may be adjusted through the Velcro portion. In the upper limb stabilizing apparatus according to an embodiment of the present disclosure, the arm fixing portion and the hand fixing portion may be formed as a net. In the upper limb stabilizing apparatus according to an embodiment of the present disclosure, the arm resting portion and the hand resting portion may be arranged to have a first angle. In the upper limb stabilizing apparatus according to an embodiment of the present disclosure, the hand resting portion may be formed in a triangular prism shape and an angle between a ground surface and a triangular slope of the hand resting portion may form a second angle. In the upper limb stabilizing apparatus according to an embodiment of the present disclosure, the hand fixing portion may include a protruding first fixing portion and a second fixing portion, wherein the first fixing portion and the second angle may be arranged to have a third angle therebetween. In the upper limb stabilizing apparatus according to an embodiment of the present disclosure, the hand fixing portion may include a hole portion into which a thumb is inserted. In the upper limb stabilizing apparatus according to an embodiment of the present disclosure, a double-sided adhesive tape may be attached to a rear portion of the arm resting portion. Other aspects, features, and advantages other than those described above will become apparent from the detailed descriptions, claims and drawings for carrying out the following disclosure. Advantageous Effects An upper limb stabilizing apparatus according to an embodiment of the present disclosure maintains a supination posture of a forearm of an upper limb paralysis patient on a lab board, thereby preventing possibilities of occurrence of negative deformation and contracture of the forearm, which may occur when the forearm maintains a pronation posture. Also, an upper limb stabilizing apparatus according to an embodiment of the present disclosure deforms a wrist and fingers to a flexion posture instead of an extended posture, thereby preventing possibilities of occurrence of negative deformation and contracture of the wrist and fingers, which may occur when the wri
