The near field cover (1) is made of material impervious to liquid and humidity, especially a rubbery plastic sheeting. The hole (6) in the middle is roughly shaped like a cuff. The peripheral edge (7) of the near field cover covers the hole through a washable surrounding cover (2) larger in size than the near field cover. The surrounding cover has an absorbent surface and extends beyond the peripheral part of the near field cover. The near field cover is joined by a detachable adhesive connection to the surrounding cover so as to be germ proof, around the peripheral edge. |
