Patent Name: Elevation Pad and Auxiliary Limb Device

Patent number：ZL  2017  3  0236630.3

Purpose: The product is intended to be used for breast cancer patients after operation. When the patients lie in supine position, the affected limbs are raised and cushioned on the shoulder and affected limbs of the affected side, so as to make the shoulder joint adduction and the affected limbs elevated, so as to prevent and reduce the occurrence of edema of the affected limbs of the patients after operation, and to facilitate the rehabilitation of the affected limbs.

Innovation point: Self-designed new type of limb edema elevation pad after breast cancer surgery, its innovation lies in: 1. Combining with ergonomics, using unique deep concave V shape and elbow function radian design, the arm is placed in the groove of the elevation pad, which makes the arm not easy to slide, and conforms to the body's physiological shape, effectively maintains the upper limb functional position of 15-20 cm, is conducive to venous blood reflux, and promotes blood flow. The inflow edema subsides; 2) Raise the elliptical finger grip ball outside the cushion, which is not easy to slip during exercise, and make all five fingers get exercise at the same time, which can enhance the afterload of upper arm muscle contraction, facilitate blood and lymphatic reflux and circulation of upper limbs, and promote functional rehabilitation of affected limbs. In addition, the ball grip is based on the effective lifting of the affected upper limb, and the joint action of the affected limb lifting and ball grip is aimed at promoting venous reflux better. Thirdly, the edema lifting pad of the affected limb can raise the shoulder and avoid the abduction of the affected shoulder joint, so that the wound surface of the axillary region can be attached well and the wound healing of the axillary region can be promoted. Fourthly, the self-made lifting pad is made of breathable high-elastic high-temperature resistant sponge. It is not easy to be flattened by the weight of the arm itself, which can ensure the effective elevation of the angle, and is comfortable and flexible, so that patients can easily accept it; The elevation cushion jacket is made of waterproof PU cloth material, and the jacket is made of functional fabrics, which has the functions of bacteriostasis, mite removal, odor prevention, air permeability, moisture absorption and convenient cleaning and disinfection.

Innovative solutions: consult the domestic and foreign literature and summarize, according to which self-designed breast cancer surgery limb elevation pad, refer to the average length of healthy female upper limb, design the length and width of the affected limb elevation pad, and consider the normal female upper limb physiological function radian. The design drawings will be sent to the professional manufacturers for consultation and production. The finished products should be tried by patients with different height, weight and difference (patients'informed consent to participate in this study). After repeated modification and trial, the patients will complain comfortably and the doctors and nurses will be satisfied to achieve the desired design purpose, and no defects of the product will be found. The effect of the product was evaluated by clinical trial.

Objective: To design and develop a limb elevation pad for breast cancer patients after operation, which is conducive to blood and lymphatic reflux and circulation of upper limbs. It can prevent and reduce the occurrence of limb edema after operation, promote edema subsidence, alleviate pain and help patients recover limb function as soon as possible. At the same time, the limb edema elevation pad can elevate the shoulder, avoid shoulder joint abduction, and make the axillary wound adhere well, promote axillary wound healing, and promote the rehabilitation of the affected limb.
