Abstract
A sealing system that includes a switchable drape is presented. The drape provides enhanced sealing by using a high-strength adhesive. In one instance, the switchable drape has a plurality of perforations through which a switching solution may be delivered to the high-strength adhesive. The switching solution causes the high-strength adhesive to become less adhesive so that the switchable drape may be removed more easily. Other systems, methods, and drapes are presented.
Claims33
A sealing system for use in treating a tissue site on a patient with reduced pressure, the sealing system comprising:
- an outer layer formed from a drape material and having a first side and a second side, wherein the outer layer is formed with a plurality of perforations extending through the outer layer;
- a high-strength adhesive coupled to the second side of the outer layer, wherein the high-strength adhesive has a first side, a second side, and a tackiness;
- and
- a switching solution, wherein when the switching solution is applied to the high-strength adhesive, the tackiness of the high-strength adhesive decreases.
A method of manufacturing a switchable drape, the method comprising:
- supplying an outer layer formed from a flexible drape material having a first side and a second side;
- perforating the outer layer to form a plurality of perforations;
- applying a high-strength adhesive to the second side of the outer layer, wherein the high-strength adhesive has a first side and a second side and wherein the high-strength adhesive covers the plurality of perforations;
- applying a first release member to the first side of the outer layer;
- and
- applying a second release member to the second side of the high-strength adhesive.
A kit for forming a seal over a portion of a patient's body, the kit comprising:
- a switchable drape;
- a switching solution;
- wherein the switchable drape comprises:
- an outer layer formed from a drape material and having a first side and a second side, wherein the outer layer is formed with a plurality of perforations extending through the outer layer,
- a high-strength adhesive coupled to the second side of the outer layer, wherein the high-strength adhesive has a first side and a second side,
- a first release member releasably coupled to the first side of the outer layer, and
- a second release member releasably coupled to the second side of the high-strength adhesive;
- and
- wherein, once applied, the switching solution lessens the adhesive strength of the high-strength adhesive.
A method of treating a patient with reduced pressure, the method comprising:
- deploying a manifold adjacent to the tissue site;
- deploying a switchable drape over the manifold to create a sealed space, wherein the switchable drape comprises:
- an outer layer formed from a drape material and having a first side and a second side, wherein the outer layer is formed with a plurality of perforations extending through the outer layer, and
- a high-strength adhesive coupled to the second side of the outer layer, wherein the high-strength adhesive has a first side and a second side;
- supplying reduced pressure to the sealed space;
- disposing a switching solution on the first side of the outer layer of the switchable drape;
- and
- removing the switchable drape from the tissue site.
A method of treating a tissue site on a patient with reduced pressure, the method comprising:
- deploying a manifold proximate to the tissue site;
- deploying a medical drape over the manifold to create a sealed space;
- supplying reduced pressure to the sealed space;
- terminating the reduced pressure supplied to the sealed space;
- creating perforations through the medical drape;
- applying a switching solution onto the first side of the drape;
- and
- removing the drape.
A sealing system for use in treating a tissue site on a patient with reduced pressure, the system comprising:
- an outer layer formed from a drape material and having a first side and a second side, wherein the outer layer is formed with a plurality of perforations extending through the outer layer;
- a high-strength adhesive having a first side and a second side;
- a soluble layer coupled to the second side of the outer layer and the first side of the high-strength adhesive;
- and
- a switching solution, wherein the soluble layer is operable to substantially dissolve when wetted with the switching solution.
A method of treating a tissue site on a patient with reduced pressure, the method comprising:
- deploying a manifold proximate to the tissue site;
- deploying a sealing system over the manifold to create a sealed space containing the manifold, wherein the sealing system comprises:
- an outer layer formed from a drape material and having a first side and a second side, wherein the outer layer is formed with a plurality of perforations extending through the outer layer,
- a high-strength adhesive having a first side and a second side,
- a soluble layer coupled to the second side of the outer layer and the first side of the high-strength adhesive, and
- a switching solution, wherein the switching solution is operable to substantially dissolve and decrease the adhesive strength of the of the high-strength adhesive;
- supplying reduced pressure to the sealed space;
- applying the switching solution onto the first side of the outer layer until the soluble layer is substantially dissolved;
- and
- removing the sealing system.
A sealing system for use in treating a tissue site on a patient with reduced pressure, the system comprising:
- an outer layer formed from a drape material and having a first side and a second side;
- a high-strength adhesive having a first side and a second side;
- a wicking layer disposed adjacent to at least a portion of the high-strength adhesive and having a plurality of wicking-layer ends extending to at least a peripheral portion of the high-strength adhesive;
- a switching solution, wherein the switching solution is operable to lessen the adhesive strength of the of the high-strength adhesive;
- and
- wherein the wicking layer is operable to transport the switching solution from the wicking-layer ends to at least the peripheral portion of the adhesive.
A method of treating a tissue site on a patient, the method comprising:
- deploying a manifold proximate to the tissue site;
- deploying a sealing system over the manifold to create a sealed space containing the manifold, wherein the sealing system comprises:
- an outer layer formed from a drape material and having a first side and a second side,
- a high-strength adhesive having a first side and a second side,
- a wicking layer adjacent to at least a portion of the high-strength adhesive and having a plurality of wicking-layer ends extending to at least a peripheral portion of the high-strength adhesive,

- wherein the wicking layer is operable to transport the switching solution from the plurality of wicking-layer ends to at least the peripheral portion of the adhesive;
- supplying reduced pressure to the sealed space;
- applying the switching solution onto the wicking-layer ends until the adhesive strength of the high-strength adhesive is decreased at least at the peripheral portion;
- and
- removing the sealing system.
