Wrist rest support

摘要

An apparatus for supporting the wrist of a keyboard operator during repetitive keyboard operations is disclosed. The apparatus comprises a bladder having an elongated length and an arcuate cross-section, and enclosed sealed ends. The bladder contains a viscous fluid for supporting the wrist of the keyboard operator when the operator is engaged in repetitive keyboard operations. An outer shell completely surrounds the bladder and contacts the wrist of the operator. The outer shell has an aperture adapted to receive the bladder and remove the bladder when it is desired to wash the outer shell. The outer shell is fabricated from a material that will withstand repeated machine washings and will maintain a fresh odor-free aroma and a pleasant-to-the-touch, itch-free feeling. The viscous fluid contains about between 0.5% to 5.5% hydroxy propyl methylcellulose with the balance being water. The viscous fluid supports the wrist of the operator and allows unimpeded flow of blood through the wrist of the keyboard operator. The bladder is fabricated from an elastomeric material, preferably frosted vinyl plastic. The ends of the bladder are sealed to hold the viscous fluid in the bladder without any possibility of leakage.
