Abstract
Provided herein is a system and method for coupling a wearable therapy system to a dressing and detaching the wearable therapy system from the dressing. One aspect provides a system including a drape with a switchable adhesive layer and a therapy system adhered to the drape via the switchable adhesive layer. The therapy system includes one or more radiation sources that can emit radiation wavelengths (e.g., light or electromagnetic waves) to impinge upon the adhesive and deactivate the adhesive when it is desired to remove the therapy system from the drape.
Claims19
A radiation deactivated adhesive drape having an inner surface configured to be coupled to tissue and an outer, non-tissue facing surface, the radiation deactivated adhesive drape comprising:
- a switchable adhesive disposed on the outer, non-tissue facing surface of the radiation deactivated adhesive drape the switchable adhesive being configured to adhere the radiation deactivated adhesive drape to a medical therapy unit, the switchable adhesive including:
- a radiation-sensitive adhesive layer having at least one release agent disposed within the radiation-sensitive adhesive layer, wherein the at least one release agent is configured to weaken a bond of the radiation-sensitive adhesive layer to a surface upon exposure to at least one of a plurality of radiation wavelengths;
- and
- a removable blocking layer having at least one blocking agent disposed within the removable blocking layer, wherein the removable blocking layer blocks the at least one of the plurality of radiation wavelengths from exposing the radiation-sensitive adhesive layer.
A medical therapy unit for medical fluid collection for attachment to a radiation deactivated adhesive drape, the medical therapy unit comprising:
- an adhesive layer receiving area disposed on an outside surface of the medical therapy unit configured to allow a passage of at least one of a plurality of radiation wavelengths through the adhesive layer receiving area;
- a radiation source disposed within the medical therapy unit adjacent to the adhesive layer receiving area and configured to emit the at least one of a plurality of radiation wavelengths;
- and
- a radiation source controller having at least one processor configured to control an ON/OFF state of the radiation source;
- wherein the adhesive layer receiving area is configured to receive a switchable adhesive including a radiation-sensitive adhesive layer having at least one release agent disposed within the radiation-sensitive adhesive layer, wherein the at least one release agent is configured to weaken a bond of the radiation-sensitive adhesive layer to a surface upon exposure to the at least one of the plurality of radiation wavelengths, and further comprising:
- a negative pressure generation unit configured to transmit one or more gasses within the medical therapy unit;
- a flexible pouch having a first end coupled to the negative pressure generation unit and a second end coupled to the adhesive layer receiving area, wherein the flexible pouch is configured to enable passage of the one or more gasses and absorb and/or wick wound fluids;
- and
- a filter disposed at the second end of the flexible pouch.
A method of operating a medical fluid collection system, the method comprising:
- adhering a medical therapy unit to a drape having an inner surface configured to be coupled to tissue and an outer non-tissue facing surface, the adhering including:
- removing a removable blocking layer from a radiation-sensitive adhesive layer disposed on the outer, non-tissue facing surface of the drape;
- and
- attaching the radiation-sensitive adhesive layer to an adhesive layer receiving area disposed on an outside surface of the medical therapy unit;
- and
- detaching the medical therapy unit from the drape, the detaching including:
- activating a radiation source disposed within the medical therapy unit adjacent to the adhesive layer receiving area and configured to emit at least one of a plurality of radiation wavelengths;
- exposing the radiation-sensitive adhesive layer to at least one of the plurality of radiation wavelengths, wherein the radiation-sensitive adhesive layer is deactivated upon exposure to the at least one of a plurality of radiation wavelengths;
- and
- removing the medical therapy unit from the drape.
