Systems, devices, and methods of the present application can accelerate and reduce medical complications associated with healing of amputation wounds. The devices and methods utilize a compression structure and negative pressure to cause the amputation wound to preferentially close from the deepest portion of the wound to the shallowest portion.

A protective cover for the protection against contamination from body and/or irrigation fluid during treatment of wounds/ulcers includes a first opening to be placed on a patient and a second opening for inserting a handpiece. The protective cover includes a fluid-tight and flexible hollow body that defines a treatment chamber having a shape that adapts to motion of a handpiece. The hollow body may include a stiffening element for keeping the first opening in an open state during treatment. Additionally, a device for the irrigation of wounds or ulcers, such as for debriding dead body tissue by way of a micro water jet, may include a hand-operated lance with a nozzle for producing an irrigation fluid jet, such as a micro water jet. The lance may be inserted through the second opening of the protective cover so that the nozzle is located within the treatment chamber of the protective cover.

A bandage for applying to and protecting a wound or the like comprises generally of a central cone piece with a plurality of attached legs. In a second embodiment of the present invention, the bandage comprises generally a substantially circular mid-piece with a center region; a proximal first flexible strip end; and a distal second flexible strip end. The substantially circular mid-piece with a center region is perforated along a radius from about the center region to a circumference of the substantially circular mid-piece and the proximal first flexible strip end is perforated longitudinally along a midline from about an end of the proximal first flexible strip to the circumference of the substantially circular mid-piece.

A device for protecting an umbilical stump-catheter interface, includes: a shield having a wall that defines a cavity for accommodating an umbilical stump, wherein the shield further includes a base for attachment to a patient; and an opening at the shield for allowing an umbilical catheter to extend therethrough. A method for protecting an umbilical stump-catheter interface, includes: providing a device having a shield with a wall that defines a cavity for accommodating an umbilical stump, wherein the shield further includes a base for attachment to a patient, and wherein the device further includes an opening at the shield; shielding the umbilical stump from an environment using the shield; and accommodating an umbilical catheter using the opening at the shield.

A wound dressing has a base bandage and a top bandage. The base bandage may include a top surface and a bottom surface. The base bandage may be configured to adhere to a user's skin via the bottom surface. The top bandage may also include a top surface and a bottom surface. The bottom surface of the top bandage is configured to adhere to the top surface of the base bandage.
