[Design of an upper limb elevation cushion for hand surgery]

Area of Science:

• Orthopedic surgery
• Rehabilitation devices
• Biomedical engineering

Background:

• Upper limb injuries are common in hand surgery, necessitating arm elevation for recovery.
• Current methods using pillows or clothing offer inadequate support and fixation, leading to suboptimal results.
• Effective post-operative arm elevation is crucial for reducing swelling and promoting healing.

Purpose of the Study:

• To introduce a specially designed upper limb raising pad for improved post-operative arm support.
• To address the limitations of conventional methods in stabilizing and elevating the affected limb.
• To enhance patient recovery by providing adjustable and secure arm positioning.

Main Methods:

• The device features a shell, mounting plate, strut, elastic band, and spring mechanism.
• Adjustable strut position via spring allows for variable inclination angles of the mounting plate.
• The elastic band secures the limb once the desired height and angle are set.

Main Results:

• The device enables free adjustment of the affected limb's raising height.
• Effective fixation of the upper limb is achieved, minimizing slippage.
• Demonstrates potential for significant reduction in limb swelling and improved recovery.

Conclusions:

• The designed upper limb raising pad offers a superior solution for post-operative arm elevation compared to traditional methods.
• Its adjustable height and effective fixation promote faster recovery by reducing swelling.
• The device is recommended for widespread clinical adoption in hand surgery and rehabilitation.
