US 10,568,785 B2 · Protective cover

Abstract

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.

Dependent claims

A protective cover for protection against contamination from body and/or irrigation fluid during treatment of wounds or ulcers, said protective cover comprising:

a first opening to be placed on a body part of a patient;
and a second opening adapted for insertion of a handpiece for wound or ulcer treatment, wherein said protective cover comprises a hollow body that is fluid-tight and flexible, and which in an interior defines a treatment chamber having a shape that adapts to a motion of said handpiece;
said hollow body is provided with at least one stiffening element for keeping said first opening in an open state during treatment;
and said stiffening element extends around a longitudinal axis of said hollow body in a helical shape over at least part of a length of its shell;
wherein said hollow body is formed having a funnel shape, where its larger opening forms said first opening and its smaller opening is covered with a transparent plate for visually monitoring a treatment area;
and wherein said stiffening element is composed of elastically resilient material, in particular of elastically resilient plastic, the elasticity of which during the treatment allows compression and expansion of said funnel-shaped hollow body in the direction of its longitudinal axis.

a second opening adapted for insertion of a handpiece for wound or ulcer treatment, wherein said protective cover comprises a hollow body that is fluid-tight and flexible, and which in an interior defines a treatment chamber having a shape that adapts to a motion of said handpiece;
the hollow body is formed from a web of material that is composed of one or more layers, ends of which are connected to each other by a seam;
and said hollow body is provided with at least one stiffening element for keeping said first opening in an open state during treatment wherein said hollow body is formed having a funnel shape, where its larger opening forms said first opening and its smaller opening is covered with a transparent plate for visually monitoring a treatment area;
and wherein said stiffening element is composed of elastically resilient material, in particular of elastically resilient plastic, the elasticity of which during the treatment allows the compression and expansion of said funnel-shaped hollow body in the direction of its longitudinal axis.
