Abstract: A protective covering for a lesion comprises a frame for adhering to the skin of a patient and for surrounding a lesion. The frame has a central opening and a generally L-shaped cross section including a wall, and a base that surrounds the lesion and attaches to the patient's skin with an adhesive. One end of the wall extends perpendicularly from the base, extending around the central opening. The free end of the wall includes a peripheral recess wherein a rim of a cover is received. The cover aligns with the opening and the rim extends fully around the cover so that when the frame base is attached to the patient's skin surrounding a lesion, and the rim of the cover is sealingly received in the recess of the wall, a sealed space is provided enclosing the lesion to protect it from the water. The cover may be put on and taken off the frame many times while the adhesive connection between the frame and skin remains intact.

Abstract: A shoe, boot, sneaker, etc. incorporates a foot-actuated pump which is connected to one or more expandable air bladders located in portions of the footware where contour fitting is desirable. Walking or running actuates the pump. An adjustable relief valve connected to the bladder releases air when a preselected pressure is exceeded. The relief valve is accessible externally for easy adjustment by the wearer. Regardless of the external ambient temperature or degree of user activity, the pump, in conjunction with the relief valve, maintains a preselected pressure and assures that the selected fit between the user's foot and footware is maintained at all times.
